  • Uhm, for those of you who may not know the Academy forum

  • is a program that is organized and funded by PAMKA. Uh, it is to bring

  • to campus outstanding speakers who will engage our students and our faculty

  • and our families and it is also our pleasure to be able to open it up to

  • the larger community. So we welcome you all. We're really delighted that you've

  • braved the elements to join us tonight

  • Before we get going, uh, with our program tonight there are just a couple people that i want to thank

  • for making it possible for us. Uh, first Amy South. Amy, where are you?

  • Amy's around somewhere. Amy is our community vice president

  • There she is, in the back

  • she is uh, ultimately, responsible for, uh, the entire event tonight

  • Next is Lucy [Botsick??]. Lucy is in the doorway up there. Lucy has

  • executed every single detail for tonight.

  • We have Trish Perlmutter

  • Trish has sheparded this program from the very beginning

  • And last but not least,

  • Judy Polonofsky and Debbie Kozak who make absolutely everything

  • happen for us here at MKA So thank you very much

  • So now, without further ado it's my pleasure to introduce

  • the headmaster of the Montclair Kimberly Academy, Tom Nammack

  • Good evening, and welcome. I'm delighted to welcome you to the Monclair Kimberly Academy

  • And I want to also thank again our parents' association.

  • They have made this evening possible for us

  • while the program

  • is free of charge

  • it's not clear expectations

  • for how we will conduct ourselves as an audience

  • I have a couple things I'd like to ask of you

  • Please, there's to be no

  • electronic recording

  • audio or video

  • please don't hold your phones up to take pictures

  • mostly because it distracts the people behind you

  • and we'd really like to focus on our very special guests this evening

  • it's my privilege to introduce our guests

  • i think they're well known to all of you

  • but I do want to say a couple things about them

  • Doctor Tyson

  • has been a frequent guest on the Colbert report

  • but, uh, or "Report" I guess is the proper

  • pronunciation

  • We're delighted that he's here

  • and we are also delighted and, uh

  • um... very grateful

  • that mr stephen colbert has agreed to interview him

  • for our benefit

  • Stephen Colbert

  • comedian, author

  • and host of the Colbert Report

  • is both one of the funniest

  • and possibly the bravest comedians of our time

  • I want you to consider his performance

  • at the national press club dinner in 2007

  • as he, uh, as he stood just a few feet from the President of the United States

  • known the rest of us as the most powerful man in the world

  • Dr. Neil deGrasse Tyson

  • astrophysicist, Director of the Hayden Planetarium

  • author of nine books, teacher, lecturer

  • host of Nova's four-part series "Origins"

  • and member of two presidential commissions

  • on United States aerospace industry

  • and the future of our country's space exploration

  • Dr. Tyson has a gift for working successfully

  • within the realms of research,

  • education, and policy formation

  • i owe you all an explanation about our theater tonight

  • what you see on stage

  • is the beginning of a set

  • for a seventh-grade production of "Romeo and Juliet"

  • this year's selection

  • for what is as i said an annual performance

  • and I think it's fitting that Dr tyson is going to warmup the stage

  • for the two most famous star-crossed lovers in all of American literature

  • it occurred to me that there are few things

  • that stephen colbert

  • and Neil Tyson have in common

  • and I wanted to comment on them

  • both of them

  • share

  • an over-arching purpose

  • to make sense of the world

  • They also share a common strategy

  • They often look to the stars

  • human or heavenly

  • for evidence of how things work

  • though Stephen Colbert is far tougher

  • on the objects caught in his gaze

  • Whereas Dr. Tyson is only known

  • to have obliterated Pluto.

  • they share methods in their respective fields, whether it is the search

  • for evidence that makes sense of the world and the universe

  • or the creative construction of questions and tests

  • by which the truth and significance of who

  • or what is before them are evaluated

  • Perhaps then,

  • they both have something in common with william shakespeare

  • the desire to provide their audience with a lens

  • to see the world

  • from the previously unconsidered

  • point of view

  • and not just as others would have us see it

  • So while the stars may be dazzling

  • training and instinct appear to have taught each of them

  • to look away from celestial bodies

  • i'm really sorry i had to get that bad cliche in there somewhere

  • and to consider the effects

  • that those celestial bodies have on everything

  • and everyone around them

  • In addition to the challenge of questions

  • that each of them

  • make us confront, their work

  • has given the world a little more of that very rare

  • and gem-like substance

  • known as the truth

  • Or in Stephen Colbert's case: "truthiness"

  • and we are very grateful. ladies and gentlemen

  • Mr. Stephen Colbert

  • and Doctor Neil deGrasse Tyson

  • "Romeo, Romeo, wherefore art thou Romeo"

  • Uh, I don't know

  • Neil, thanks so much for coming Yeah ... thank you.

  • Mr/Dr Neil deGrasse Tyson is

  • he's been on my show six times

  • and often when I come out

  • to brief the audience before I do my show

  • they ask me "who's your favorite guest of all time?"

  • and I say, not just for volume, but it's Neil DeGrasse Tyson

  • but because not only uh... do I love what neil knows

  • but uh, I love

  • that he loves what he doesn't know

  • always interested in the next thing to learn (Oh yeah) and always rolled to whatever

  • idiocy my character wants to throw on him

  • I think the only time i ever surprised you as you told me a

  • a little while ago

  • uh was i asked you should uh... should scientists go to Argentina or hike

  • the Appalachian trail

  • If they want people to talk about them

  • it's the universe talking there the universe [??]

  • Yeah that ... I missed that one Yeah you missed that news story

  • To go on his show

  • it's like the hardest interview ever

  • I have to, like, I'm laden with current events just

  • to mix with my science cause I don't know where he's gonna come at me

  • and I gotta be, like, ready with seven tennis rackets

  • to hit it back

  • And on set with that one news story remember with that guy, was it south carolina guy

  • who remembers

  • He goes to Argentina and becomes well-known for having done so and you ask me straight-out

  • should scientists

  • visit Argentina more often to become better known

  • and it just went.. I just

  • you aced me on that one (You're welcome)

  • Now, Neil, we've got a lot of talk about tonight (yeah) a lot of

  • subjects science is a big thing but i want to start off with

  • this is not a bribe (that's alright)

  • I want to start off with .. with these chairs I feel myself sliding

  • No, no

  • This stage is not level

  • oh welcome to the barn raising

  • Didn't realize we were speaking before the Omish tonight

  • That's gonna

  • make it tought to talk about science and technology

  • All right, Neil

  • i want to start uh...

  • i want to start, in a broad way

  • are you Tweeting now, or are you actually trying to interview me?

  • no, i'm just looking at ...

  • i'm just looking at photos of myself

  • get a little work done I need a little freshen up

  • let me ask you a very basic question: science

  • from

  • "scientia", Latin, meaning knowledge

  • I didn't take Latin but I'll take your word for it

  • is it better

  • to know

  • or not to know

  • i think

  • well my blunt answer is it's better to know (alright) but i think

  • that is debatable though

  • well I said "my" answer. Someone else might have a different answer

  • for instance, Oedipus might have a different answer

  • Yeah, I mean I think

  • is .. is knowledge always a good thing?

  • I have to say yes

  • why?

  • because it empowers you

  • to react

  • and possibly even to do something about it

  • if something about it needs to be done

  • ok, but who we are

  • is what we know, right?

  • Part of who we are is what we know

  • and our identity

  • is often based on how we see the world

  • yes, and uh... personality for sure

  • and if we learn something

  • that does not jive with how we think about the world

  • won't we have to reexamine who we are? Yeah, it could mess you up

  • Once again I'll go back to Oedipus

  • He plucked his eyes out rather than know any more

  • Yeah, well, you know people back then you know, they did stuff like that

  • Yeah, people back then

  • not people today

  • so i think

  • there are people who would not know

  • who would rather ... remember the old days

  • I don't know if it still happens where a doctor would find out you had cancer, they wouldn't tell you

  • They wouldn't tell you (give it to me straight doc) Yeah and

  • why would even have to say

  • give it to me straight unless there was a day when they didn't give it to you straight?

  • If I have five years left I wanna know I have five years left

  • Cause I wanna, like

  • do something different in those five years if (Neil?) yeah?

  • I have some terrible news

  • so there are some people who don't

  • there are some people who don't value science

  • and if they don't value science

  • are they valuing ignorance? Yes, and.. but I will not pass judgment on them

  • what I will say is

  • if they have are at maximal comfort in their ignorance.. fine

  • except that they will not be the participants on the frontier of

  • of cosmic discovery

  • they will be disenfranchised

  • Hello .. hello

  • I'm sorry I've got a phone call... hello?

  • I'm sorry I have to take .. I have to take this.. Hello?

  • My mic.. my mic isn't working?

  • Hello?

  • that's better Now who's in control?

  • So they won't be in control of the next.. they won't be participants in the next cosmic discovery

  • No they won't they won't

  • not only will they not

  • be on that frontier making any discoveries

  • they're not in a position to enhance their life for having access to those

  • discoveries themselves

  • Can knowledge

  • ever be a bad thing?

  • i don't think so

  • what about actions that

  • knowledge takes us to? You think that Oppenheimer

  • when the bomb went off and he said

  • "I am become death, destroyer of worlds"

  • do you think he perhaps questioned for a moment

  • whether the knowledge they achieved that led to the creation

  • of the bomb perhaps should have been left undiscovered?

  • Do you know what he said in response to those kinds of questions?

  • Yes?

  • he said

  • because people said "Have you ursurped the power of God?"

  • and he said

  • If God didn't want this power to be there he shouldn't have put it in the atom in the first place

  • kind of an interesting point, I think

  • What he was saying that the world is accessible to us

  • so would you say

  • "Don't smelt the ore and make iron

  • and make a sword out of it because you could cut yourself"?

  • back then that's what you would .. that's the counterpart

  • statement

  • from the Iron Age.

  • And if you were around back then you'd be sitting in this chair saying

  • "Don't make the sword,

  • because you will unleash evil on the world"

  • OK, I'll step back from don't make the sword how about

  • "don't lick flag pole in February"

  • Yeah, that

  • You will learn something

  • you will learn something but at a price, Neil

  • that'd be data.. it's a data cost

  • That is a data cost for that, isn't it? Yeah

  • Also: Adam and Eve...

  • They ate of the tree of knowledge (of knowledge)

  • of good and evil (Yeah) and they paid a price (yeah)

  • so god does put things into atoms he doesn't want us to know about

  • Yeah, I ..

  • However, I think

  • Yes?

  • I don't want to blame the knowledge

  • I want to blame

  • the behavior of people in the presence of the knowledge so maybe

  • we need better knowledge management

  • do you think that scientists .. you can applaud him.. he's the hero

  • Well how about this: do you think that scientists should be allowed to do with anything

  • they can

  • I heard a big "No" over here

  • someone just said "no"

  • you know, uh, people made fun of him for doing this but

  • uh... during one of President Bush's

  • State of the Union speeches .. Bush 1 or 2?

  • Bush 2

  • Uhm, he said

  • uh... we have to .. he spoke about ... he warned against man-animal hybrids

  • And a lot of people like me

  • made fun of that

  • by showing pictures of like senator alligator man going

  • "Boooo boooo"

  • "Yay man-animal hybrids"

  • but if scientists could make man-animal hybrids, wouldn't they?

  • there are scientists who want to make man-animal hybrids

  • should we make man-animal hybrids I ask you senator tyson

  • Or should there be any limits like that? i think there's some creepy things about

  • that and i've met some scientists who

  • who would think that would be an intriguing to do

  • yes okay

  • So i think

  • we as a society

  • as a .. as a

  • democracy

  • what we should do is

  • come to some

  • understanding of what the prevailing social mores are

  • and know science should not cross those barriers and not and by the way

  • scientists are often ones

  • to try to prevent that

  • Einstein among them for example he didn't want to make the bomb

  • after he first told Roosevelt he should make the bomb, he changed his mind

  • because his conscience, his moral conscious descended upon him

  • scientists are not without moral code here

  • so as a culture and as a society we decide what

  • should be the prevailing cultural mores and i think we should all be

  • beholden to those. What do you think of the portrayal of scientists

  • uh... in movies?

  • because often often

  • for instance the scientists who make, uh

  • the terminator

  • they're the bad guys

  • scientist leads to the terminator or they create the super bug that wipes out

  • the world

  • or or they enrage the monster at the bottom of the sea

  • When you part the curtains and

  • at the bottom of all that

  • there's a politician funding that research

  • Is this working again? It is? No..

  • He says yes, you say no

  • we're getting we're getting bad data

  • we're good .. That was good That's good? oooh yeah

  • So scientists don't

  • lead marching armies

  • scientists don't invade other nations

  • scientists

  • yes we have scientists who invented

  • the bomb

  • yes but somebody had to pay for the bomb and that was taxpayers

  • that was war bonds

  • there was a political action that called for it

  • so everyone blames the scientist. We are collectively part of the society

  • that is passing.. that is

  • that is

  • that is

  • using are not using

  • to it's benefit or to it's detriment

  • the discoveries made by science

  • and at the end of the day

  • a discovery

  • itself is not moral, it's our application of it

  • the takes that .. that has to pass that test

  • would you agree that there's a .. there's a distrust of science on a certain level

  • in our country

  • I mean unless it's, you know

  • can they grow my hair back? Yeah right

  • science.. or do other things to your anatomy yes, exactly .. exactly

  • science.. I've gotten those emails

  • science

  • science is sometimes distrusted because it is it is more complex than the average

  • person can understand. I think that is the core of it

  • the distrust is not because of what it can do but because of what it

  • because people don't understand how it does what it can do. And that .. that

  • absence of understanding or misunderstanding

  • of the power of science

  • is what makes people afraid of it

  • and so

  • i remember back when they first split the atom you know "shouldn't split the atom" or

  • or shouldn't .. you hear this at every discovery that happens in science

  • there's a mystery to it

  • for example irradiated foods in France they call it "frakenfood", alright

  • which is kind of a cute word when you think about but it makes food last longer and your

  • healthier for it, you don't get sick from it

  • and so.. from it turning bad, in fact

  • Nasa does it all the time.

  • Nasa can make a slab of meat you wouldn't necessarily

  • put this in your refrigerator but Nasa can make a slab of meat that will last thirty years

  • I tasted it and? delicious?

  • you know there's some rest.. it reminded some restaurants food reminds me of what

  • that tasted like but i'm just saying that

  • just because you don't understand it doesn't mean it's bad for you

  • go figure out how it works.

  • That's why we need a scientifically literate electorate so that when we go to the polls

  • you can make an informed judgement

  • and you can draw your own conclusions, rather than turning to a particular TV station

  • to have your conclusions handed to you.

  • Now you know Arthur C. Clarke .. Comedy Central excepted (exactly)

  • Arthur C. Clarke's famous dictum about sufficiently advanced technology.

  • Yes, it is .. Arthur C. Clarke had several, uhm

  • uh, laws of

  • culture and the world one of which was

  • any sufficiently advanced technology

  • is indistinguishable from magic.

  • So..

  • if something gets too complex for the average person to understand

  • it's magic .. and you have powers that i don't trust

  • because I don't know what you're going to do with it next

  • whereas if you understood how it worked

  • you'd say "Hey, give me one of those" I mean, that's how that would work

  • That's how.. that's how that plays out

  • do you think that's where the debate over

  • i think that's where the debate over uh...

  • evolution and creation science comes

  • is that the

  • complexity of evolution

  • is so grand

  • that it is hard to conceive

  • of how the incremental changes come and once something becomes so complex

  • that I can't understand it

  • there's nothing between that

  • and God saying "Let it be"

  • Well one of the beauties of evolution is that

  • that complexity does not come about from complex ideas

  • the ideas are actually quite simple

  • and you can show on a computer how those simple forces

  • can generate complexity given enough time and enough variation in environment

  • which is just what the history of the Earth supplies

  • so so science literacy is an important part of what it is to be an informed

  • citizen of society

  • let's get away from our understanding of science, or lack thereof

  • and get to science itself ok ok I'm with you

  • here's a transition from talking about

  • us mixing science and religion

  • and getting back to science

  • "God is truth", people think

  • ok, some believe God is truth

  • Truth is beauty

  • is there anything in science

  • to you that is beautiful or rather what is the most beautiful thing

  • that you know of in science

  • E=mc squared

  • Really? Oh it's awesome, it is

  • so that equation doesn't just have a great publicist, it's actually..

  • because everybody knows it, everybody knows it but also, everybody knows Coke, you know

  • it's like the Coca-cola of science

  • You learn E=mc^2 before you even know what any of those symbols mean

  • you hear it in elementary school

  • oh, it's a gorgeous thing

  • it's .. what is beautiful about E=mc^2 first of all

  • tell everybody what all the pieces mean

  • Well "E" stands for "energy"

  • "m" is "mass"

  • "c"-squared is just the speed of light squared, that's just

  • ignore that for the moment. The thrust of that equation is that

  • energy and mass

  • are equivalent to each other

  • which means you can transmute one into the other

  • and back

  • would make's it extraordinary is that that hardly ever happens in our everyday lives

  • yet it's going on all the time in the rest of the universe

  • and so.. so

  • so we're in this little pocket where "E=mc^2"

  • never happens (is not visible) it's not visible it's not happening in our lives

  • no, no

  • but if it did the world would be really different

  • light coming from that bulb would all of a sudden pop into

  • a particle, and the particle would come by and it would pop back into light again

  • Would it hurt?

  • It can, yeah It can? Yeah it would sterlize you, yeah

  • The kinds of particles that would do that

  • they would sterilize you, yeah that'd be bad

  • I've had my kids

  • It goes on in the center of the sun it went on at the Big Bang

  • it goes on throughout the universe

  • wherever it's hot and heavy

  • But what is beautiful about it to you? It's simple

  • It's simple, yet it accounts

  • for hugely complex things and for me

  • that is where the beauty lies in the truth

  • Now if i had to give you a complex

  • theory to understand a complex phenomenon

  • You know, send me home

  • because what's the point?

  • Now there's no tablet in the sky that said

  • it had to be simple to end up being complex

  • it's just a remarkable fact about the universe

  • so why not celebrate it?

  • The fact that pi ...

  • pi ...

  • that ... pi right?

  • Let's say the numbers together

  • 3 point 1 4 1 5 9 2 6 5 3 ..

  • we got a few geeks over here looks like we got a geek thing going on over there

  • not bad, not bad

  • The fact that you take a circle of any size

  • a circle the size of the universe itself

  • and divide it by its own radius

  • and you get that number

  • that's beautiful

  • i have to pause, and I get misty

  • Thinking of [???]

  • I'm sorry that's just ..

  • another one

  • .. another one that the atoms and molecules in your body

  • are traceable to the crucibles in the centers of stars

  • that manufactured these elements

  • over its lifespan

  • went unstable

  • on death

  • exploding its enriched guts across the galaxy

  • scattering it into gas clouds that would ultimately collapse

  • and make a star

  • and have the right ingredients to make planets

  • and people

  • which means, we are part of this universe

  • as i've said many times and this goes back not only are we in the universe

  • the universe is in us

  • that is a profound concept

  • and it was ... i think it's the greatest gift that astrophysics gave culture

  • in the twentieth century

  • it was a research paper in 1957 and i say that because one of the

  • authors just died like two days ago

  • Geoff Burbidge.. Burbidge, Burbidge, Fowler, and Hoyle

  • one of the most famous research papers that no one ever heard of

  • you know why? i think

  • because it had 4 authors, not just one and it took a decade to figure out

  • and it wasn't just somebody burning the midnight oil so it doesn't

  • lend itself to poetry or screenplays because it's a collaboration so nobody wrote

  • about it

  • but we knew that we are star stuff

  • we knew that we are stardust at the middle of the twentieth century

  • that connects us to be universe like no other fact

  • that's beautiful

  • sounds like you have written poetry about it

  • Well, once it gets in you have you know

  • the only way it comes out is poetically .. no

  • You write poety, you write sonnets

  • I don't know if they're sonnets but occassionally a word rhymes in it

  • and I don't know what to call it

  • but sometimes if if you feel deeply

  • about something

  • i think the greatest poetry

  • not that I'm.. I'm an astrophysicist alright, that's my disclaimer

  • but some of the greatest poetry

  • is revealing to the reader

  • the beauty in something that was so simple you had taken it for granted

  • that i think is the job of the poet

  • and so

  • the simplicity of the universe which started this

  • part of our conversation

  • i think

  • if it doesn't drive you to poetry it drives you to

  • bask in

  • the majesty of the cosmos

  • so what drew you.. you said that ..

  • the beauty of astrophysics or the gift that astrophysics gave us in the twentieth century

  • what drew you

  • to astrophysics? Take us

  • to Neil deGrasse Tyson

  • before

  • he's an astrophysicist take us to who you are now

  • I'm living in the Bronx

  • which in the vernacular would be "da Bronx"

  • and I'm in a building ... not a lot of stars

  • no There's like a dozen or so in the night sky

  • so you do not have a relationship

  • with the night sky

  • as a city dweller

  • and

  • my parents .. I have a brother and a sister ... they would take us

  • to.. each weekend we'd go to visit museums and other sort-of cultural things in the city

  • and one of those weekends we went to the Hayden plantetarium

  • the local plantetarium the one right there in Manhattan

  • and I.. you sit in the chair, the lights dim, the stars come out

  • and I said "well that's a nice hoax"

  • you know

  • That can't be real, that's

  • i'll enjoy it while there, but they think there's that many stars up there

  • what kinda.. they're pulling my leg

  • and a couple years later i go out to pennsylvania

  • in another trip we took

  • and I look up at the night sky and what

  • persists to this day

  • and what is an embarrassingly

  • urban thought

  • i look up at the night sky from the finest mountaintops in the world

  • and i look up and I say

  • "it reminds me of the Hayden plantetarium" I mean,

  • it's embarassing

  • I beg forgiveness wow

  • So strong was that imprint

  • that i'm certain

  • that i had no choice in the matter that in fact

  • the universe called me

  • and i wondered that if I'd grown up on a farm

  • and the universe and the sky was just always there

  • i wonder if that would just have become wallpaper to me

  • and I wouldn't have then been struck by it as I was at age nine

  • i'd never known anything of it

  • and then it just slaps you in the face

  • and from then on I was hooked

  • it took two years for me to figure out you can do that as a career

  • but starting at age eleven you ask me

  • you know that annoying question that adults ask kids

  • "what do you want to be when you grow up?"

  • I heard a comedian say "You know why they ask?"

  • "because they're looking for ideas!"

  • Paula Poundstone said that

  • So, if you had asked me from age eleven

  • What do you want to be when you grow up

  • i would have told you a flat-out: astrophysics

  • astrophysicist

  • and my whole life aligned to that got a telescope, got a camera, photographed it

  • all my science fair projects .. one was getting the spectrum of the sun and analyzing

  • features in the spectra

  • I ...

  • built the spectroscope

  • so i was like Nerd Kid. card-carrying

  • But I was bigger than other kids so

  • I was insulated from a lot of what might otherwise happen to nerd kids

  • You wrestled, too. I was captain of my high-school wrestling team

  • I've seen you in that wrestling outfit

  • You can rock a singlet. well done. now..

  • "Singlet" is what you call the one-piece ...

  • they know

  • So, you became.. you wanted to become an astrophysicist

  • that leads me to another question which is

  • you know "Is it better to not know? it's better to know"

  • uhm

  • Can it be beautful? yes, it can be beautiful.

  • Is science

  • a thing

  • or is it a way to look at the world

  • Is it a verb, or is it a noun?

  • It is .. both.

  • the world is not just "is it this or that?"

  • "Is it a planet or not a planet?" It's sometimes

  • you must choose!

  • It's fuzzier than that

  • sometimes.. so if i know .. if I have a lot of facts in my head if i can absorb

  • a lot of facts, am I a scientist? Facts? no

  • No, you're a ... fact memorizer

  • In fact... I'll accept that as a compliment

  • our academic system rewards people who know a lot of stuff

  • and generally we call those people smart

  • but at the end of day

  • who do you want: the person who can figure stuff out that they've never seen before,

  • or the person who can rattle off a bunch of facts?

  • at the end of the day, I want the person that can figure stuff out.

  • and science say, if you were trapped on an island exactly

  • exactly

  • well you know the professor on gilligan's island

  • It's a not a matter of how many facts he can recite

  • like there's a coconut, and there's a thing and you have a ham radio

  • OK, you just (seawater) you're stirring the saltwater

  • you hook the wires up to Gilligan's fillings and you listen to his ears

  • so it's an understanding of the relationships

  • While we're on it: Ginger or Mary ann?

  • Totally Ginger

  • Ginger, completely

  • That was like .. she came around the wrong time in my life it was like

  • Ginger, all the way

  • for sure

  • so it is a way ... it is ..

  • it's a way of approaching the world

  • it's a way, not only of approaching the world

  • it's a way of equipping yourself

  • to interpret what happens in front of you

  • i think of science

  • the methods and tools that

  • enable it

  • as kinda like a utility belt that you walk around with

  • you know, and you come upon something .. Are you a superhero?

  • In your mind, are you Super Science?

  • Actually, when I was a kid, I wanted to be Mighty Mouse, when I was a kid

  • really?

  • And I wanted to sing opera as I went to save..

  • "Here I am to save the day!"

  • So it's a tool belt no, it's a .. utility belt

  • Utility belt, sorry.

  • because tools.. I'm picturing you in the singlet, with a utility belt

  • A tool belt .. the difference is a tool belt

  • you know if you have a hammer

  • as they say "you can hammer in the morning"

  • if i had a hammer, the problem is

  • If you start wielding a hammer, then all your problems look like nails

  • and maybe they're not

  • maybe it's more subtle than that

  • and so your tool kit has to be able to morph into what is necessary for

  • what it is that you confront at that moment

  • and so yes there .. you're equipped with

  • methods of mathematical analysis, methods of interpretation

  • you know some basic laws of physics so when someone says

  • "I have these two crystals if you rub them together you will get healthy"

  • So

  • rather than just discount it

  • because that's

  • that's as lazy as accepting it

  • both of those are just lazy-brain

  • what you should do is inquire?

  • So do you know how to inquire?

  • and every scientist would know how to start that conversation

  • start the conversation

  • they would say well "Where'd you get these?"

  • "what kinds of ailments does it cure?" "How does it work?" "What does it cost?"

  • "Can you demonstrate that it works"

  • And you go through this whole ... and at the end the person's in tears

  • because they weren't prepared

  • for that level of questioning

  • and, so, science literacy is ..

  • vaccine

  • against

  • charlatans of the world that would exploit your ignorance

  • of the forces of nature

  • Neil, if you don't like the crystals I gave you you can just say it.

  • and they're not working for you because you don't believe

  • Is there any science fiction you admire?

  • or that you enjoy?

  • or do you see the holes in science fiction and go "i can't enjoy that of course

  • he would know the effects of a neutron star! He doesn't know tidal forces?"

  • Do you have that problem?

  • I only have the problem

  • if the movie is

  • marketed for its accuracy

  • number one. Number two .. they gotta get some basic science right. after that, I'm OK

  • so for example in the latest star trek movie the had this like ..

  • this red

  • this liquid .. the red matter ... the red matter thank you

  • release the red matter, and you drop it into the core of a planet

  • and it turns the planet into a black hole?

  • I thought that's kinda cool

  • Now what was a little weird was Why didn't it turn the ship into a black hole?

  • Because they had this special apparatus that surrounded it

  • this special device And the apparatus did what?

  • It's the anti-black-hole apparatus. hold on.. I'm OK with that

  • See, I was not losing sleep ...

  • That didn't bug you?

  • ... over what held the black hole I didn't have an issue with that

  • Oddly, what I had an issue with was

  • they needed this drill, which is a very cool kinda .. that was the coolest thing I'd ever seen

  • (exactly) a drill that would drill to the center of your planet

  • and they drop the..

  • i'd say

  • If that would turn a planet into a black hole, from its center

  • it surely would turn into a black hole from its surface

  • but.. then what would Kirk and Sulu fight on?

  • I know, right, they had to fight on the platform

  • so, I'm OK

  • I got angry with Jim Cameron about "Titantic"

  • that's how i got angry

  • Did I ever tell you this story? You did not

  • I've never seen you this angry before

  • Hold me back

  • I can't wait to see what you have to say about "Avatar"

  • you might turn blue with rage go on.. so what was your problem with "Titantic"?

  • There's a colleague of mine who saw "Avatar" and he got home and he

  • he told his wife he wanted to paint her blue, and that didn't go over very well

  • is she ten feet tall?

  • So "Titantic", you may remember, was marketed as a film of "high accuracy" because

  • Cameron had funded this submersible to go down and

  • check out the state rooms

  • and the wall sconces and the china patterns and so they reproduced that

  • to detail

  • and so here they recreate the ship for the movie, can you double check that?

  • no because he had the submersible. You just have to trust him ok

  • You gotta trust him. So now

  • the ship sinks (yes) right?

  • Did I give away the plot to anybody here?

  • You see the movie yet? I'm sorry, ok

  • so the ship sinks I do, I remember you remember, ok

  • and there's Kate Winslet on the flow

  • remember that (yes)

  • and she's delirious This isn't the scene where she's naked

  • Oh sorry.. go on

  • No, she's on the flow.. on the.. whatever, the plank and

  • she's looking up

  • We know

  • the date, the day, the time,

  • the weather conditions, the longitude, the latitude

  • we know all of this about the sinking spot of the "Titanic"

  • There is only one sky she shoulda been looking at

  • and it was the wrong sky!

  • Worse,

  • worse than that, worse than that

  • the left side of the sky was a mirror reflection of the right side of the sky

  • So it's not only wrong, it was lazy! And I was ...

  • So halfway through they went, "Just flip it, just flip it"

  • No one'll know

  • and so, I was livid

  • I got out my finest stationary

  • and i wrote a letter to Jim Cameron

  • no reply

  • Five years later I bump into him he was on a NASA committee

  • and my sort-of presence with NASA was growing by then

  • and I bumped into him in a meeting

  • and I said Mr. Cameron, I just want to .. I just have to ask

  • you know the sky that .. is not the right.. what? what?

  • and he says "Well actually, that happened in post-production"

  • So .. so he's absolving himself of guilt

  • but I wanted him to grovel in front of my feet which he did not do

  • wait, wait .. so, I was angrier after that

  • later on

  • Wired magazine honors him

  • for "Discoverer of the year" or "Explorer of the year"

  • and they want to hold their party

  • at the Rose Center for Earth and Space

  • you don't come into MY house and get the sky wrong!

  • my microphone working?

  • you're loud enough, you don't need a microphone

  • Can you hear me now? ok

  • So,

  • he's in my house

  • and as a courtesy, they extended me an invitation to have dinner

  • with a small group of them after this award ceremony

  • So I said "yeah"

  • So, we go to dinner there's six of us at the table

  • the wine is pouring

  • So I said "Jim, I don't know if you remember but I brought this up some time ago

  • about the sky

  • and I wouldn't be so upset except that everything else you boasted was

  • so accurate

  • and we can't even check how accurate that is

  • but anybody can spend $50 for a planetarium sky program

  • and look at the sky and know that you got the wrong sky

  • What gives?"

  • And you know what he said?

  • he said "last i checked,

  • worldwide

  • Titanic has grossed

  • one point three billion dollars

  • imagine how much more it would have grossed had I gotten the sky right"

  • Oh

  • Oh, I'm so sorry

  • that ... if i had a tail, it would have been like between my legs, and I would've

  • oh I think you won that conversation

  • No actually I did

  • no he retreated into his bank account

  • Here's what happened

  • but you know that money will all eventually be gone

  • and he would still have gotten the sky wrong

  • Oh that's an interesting point that's right the sky will..

  • Outlived even James Cameron

  • However, however as dejected as I was

  • two weeks later i get a phone call

  • forgot the guy's name he calls me up and said "Is this Dr. Tyson?" I said "yeah"

  • He said, I forgot his name, "Johnny Smith"

  • I work

  • in post-production

  • for Jim Cameron

  • He is releasing a ten-year director's cut anniversary edition of the Titantic

  • and will be adding new footage

  • from the deck and he tells me you have a sky that he can use

  • Not bad (so) Not bad you got your taste, right?

  • You got a little taste of that, right?

  • Yeah, it was good.. oh no no I'm a public servant, I don't need it

  • Me too

  • So I don't, you know if you're gonna make

  • if you're gonna claim it's right then I'm gonna hold you to it

  • If you're not, then I'll just sit back and enjoy it

  • (what is) you know what I don't like? I gotta.. you know what I don't like?

  • Is the people you go see a movie with

  • who read the book first

  • Get rid of them!

  • They don't belong in the movie theater

  • Alright

  • It's like "Oh no the book was better"

  • Well get the hell outta oh excuse me

  • Get out of the movie theater

  • go back to your book

  • Leave me alone

  • Those people I can't stand

  • Stay home!

  • we should not go to the movies together

  • Now, ok, what is the what is

  • I got three different things What is the latest discovery

  • in astrophysics that we should all know about?

  • Ah, one of my favorite

  • i gotta go back maybe six months for that, eight months? may I?

  • Uhm, okay

  • well we discovered water on the Moon, that's kinda cool

  • because where you're going, you want there to be water.

  • alright that's a good thing for life

  • but what struck me the most

  • Earlier, in .. 2009

  • we discovered

  • methane

  • on mars

  • Methane

  • if you have a gas stove and you live in the city, chances are it's methane

  • it's a flammable gas, you say "well so what? who cares?" except that

  • methane

  • is the byproduct

  • it's part of the gaseous effluences

  • of anaerobic bacteria which on Earth

  • operates deep in the intestinal tract of farm animals

  • That's a very scientific way of saying

  • there are Mars farts

  • That's what you're saying, right?

  • I didn't want to say it

  • You got a "Dr" in front of your name

  • You can't say stuff like that I can't say stuff like that

  • but that means that

  • that is a possibility or is that or is that

  • "yeah there's life" and no one will come out and say it?

  • It means

  • while you can generate methane other ways

  • Such as?

  • well it's (sunlight?) it's

  • it's .. there

  • a combination of pressure, temperature, and energy source you can manufacture

  • methane (magic!)

  • so.. but

  • chemical magic, yes chemical magic

  • but it is a natural by-product of

  • bacteria that

  • thrive in the absence of oxygen.

  • And you don't have oxygen deep in your intestinal tract, neither do any farm animals

  • and and if you're down under the.. Mars doesn't have oxygen, so

  • it's tantalizing to think

  • that maybe there is

  • there are life reservoirs

  • in aquifers beneath the martian soils Speak.. as I was saying before about

  • is it better to know or not to know

  • and there are things about our own identity that we take from the knowledge

  • that we have, (yes we do) or the things that

  • or the things that we don't know

  • the assumptions of things that are not there to be known

  • And I .. instead of using the word "identity" I'd say: They have an impact on our ego

  • (yes) because the more we learn about the universe, the smaller we get

  • in time, and space, in size and so if you go .. except not the way you just described it

  • the way you described it

  • you're a supernova

  • (well I) that makes you bigger

  • well i think if you know about what's going on

  • then it's not mysterious and you're a participant in the

  • unfolding cosmos

  • otherwise

  • you are consumed by it

  • and you fear it and you shun it

  • and you say "I don't want to know that I live on a speck called Earth

  • orbiting an undistinguished star, in the corner of an ordinary galaxy

  • in an expanding void of the cosmos

  • There are some happy thoughts in there, like

  • like understanding how that worked

  • recognizing that the human brain figured that out that's kinda cool

  • There's a lot we still don't know

  • but what we do know, I think we can sit proudly

  • and celebrate

  • what we know about the universe

  • maybe not everyone of us figured.. it took a few key people like Newton and Einstein

  • but we learn what they taught us and each of them stands on the shoulders of giants

  • that came before them

  • just as the quote goes

  • but celebrate

  • not fear it

  • but if we found out

  • that there was life

  • someplace other than Earth

  • what do you think that would do

  • to our identity

  • or our ego

  • It may

  • signal a change in the human condition that we cannot foresee or imagine

  • i think it would

  • now, i think the issue would be not if we find bacterial life

  • which is kinda what we're looking for now

  • bacterial life there's no question about

  • whether in our minds eye we

  • reign supreme over bacteria although it can win

  • bacteria

  • do you know in one linear centimeter of your lower colon

  • lives and works

  • more bacteria

  • than the number of people who have ever been born in the history of the world?

  • so in fact we are just hosts

  • for bacteria to lead their lives so from the point of view of a bacteria

  • we're just a place to live

  • a dark, warm, place to live

  • but we're a planet

  • and they don't believe there's bacteria in any of the other planets

  • that'd be another that'd be interesting sci-fi

  • so the real issue is, if we find life on another planet

  • that's smarter than we are

  • that would totally mess with our ego

  • That'd be the last, like, nail in the coffin of our ego

  • that used to be, well, we're humans and we're on Earth and Earth is small

  • and the Sun, sun is insignificant

  • that'd be the last one and I don't know how we'd be able to handle that

  • do you think that there have been discoveries that have happened.. for instance

  • I have heard

  • discoveries that have changed our point of view about the universe that we are not aware of

  • that they've changed; in other words the change has been so gradual

  • we don't realize we see the world differently

  • Has E=mc^2, because

  • that's .. coming up on a hundred years

  • I'll tell you, yes it is actually well, no, we passed it

  • Last year was a hundred?

  • No, 1905, so, 2005 (OK)

  • So, I got one for you

  • in the 1920s,

  • which was a watershed decade in the history of science

  • in that decade

  • we discovered that

  • not only our galaxy, the milky way, is not the only

  • existence of anything in the universe that there are other

  • milky ways out there

  • that recently

  • 1920s ... Was it just the optics didn't exist for that?

  • We needed a big enough telescope and Edwin Hubble

  • wielded all the glass that was necessary to accomplish that

  • back in the 1920s. He's ..

  • Hubble, before the telescope, was a man and

  • had his own telescope, the biggest of its day

  • and he made that discovery

  • that there were these spiral fuzzy things in the night sky

  • we thought they were just local to us

  • They were whole other

  • systems of stars

  • hundred billion stars unto itself

  • outside of our system

  • not only was that discovered in 1926 1929 he discovers that the

  • universe is expanding

  • which means

  • it may have had a (back then) it may have had a beginning

  • if it's expanding that meant it was little-er in the past

  • well there must have been a day when it was all together in the same place

  • thus was born

  • the Big Bang

  • okay so now

  • also in that decade

  • quantum

  • quantum mechanics quantum physics

  • was discovered that is the science of the small

  • the science of electrons, protons,

  • neutrons, particles, nuclei

  • at the time you'd say

  • this is just the this is just physicists

  • burning tax money

  • cause who cares about the atom

  • I got my horse to feed, I got

  • kids, I got.. you know you got issues in society

  • yet it's quantum mechanics

  • that is the entire foundation of our technological revolution

  • there would be no computers , there would be no

  • there would be none of what you take for granted

  • your iPod, your iPhone, cell phones

  • the space program ... without our understanding of the laws of physics as

  • they operate on that atomic and molecular and nuclear level

  • and so

  • the chemist has no understanding

  • of the periodic table of elements

  • without quantum mechanics

  • to them it's just a list of elements

  • quantum mechanics tells you why this column is there

  • and that's there, why this mates with that and why that makes a molecule with that

  • that's quantum mechanics and it's unheralded

  • you asked me if there is any discovery that has changed how we live

  • It is quantum mechanics

  • and I make.. I make this point because

  • I'm ready to

  • today you hear people saying

  • "why are we spending money up there when we got problems on Earth"

  • And people don't connect

  • the time delay between the frontier of scientific research

  • and how that's going to transform your life later down the line

  • all they want is a quarterly report that shows the product that comes out of it

  • that is so shortsighted and that's the beginning of the end of your culture

  • So it's

  • so it's better to know

  • That's a really long answer to my first question. My second question

  • Let's take some questions do we have time to do that?

  • Q and A?

  • you gonna hit me in the head with a rubbed band?

  • Ok, very quickly before we get to questions here

  • How many can I ask?

  • [???] Do we have microphones or are we going around the room?

  • We can repeat the question if there aren't enough microphones to go around

  • Uh, let's start right here with just one please, sir.

  • Is there a brown dwarf star approaching?

  • okay uh...

  • dare I suggest that i think i know much more deeply

  • about what's behind that question

  • he's asking about

  • "Planet X" (do share[???])

  • that would swing by Earth in the year 2012 and tip us on our axis

  • and have it be the end of civilization as we know it. Is that right sir?

  • I heard about that.

  • Yeah, yeah.

  • I'm digging a subterranean chamber

  • (yeah) me and my kids are gonna be fine.

  • Go on, when's it get here?

  • Uh, it doesn't exist

  • moving on, next question

  • Yes no, there is no "Planet X"

  • All gravity.. all principal sources of gravity in the solar system

  • are present and accounted for

  • anything discovered now would be tiny and insignificant, like

  • Pluto's relatives

  • What do you have to say about Apophis?

  • Apophis

  • Apophis

  • an asteroid the size of the Rose Bowl

  • discovered december 2004

  • headed towards Earth

  • it's not alone, among asteroids headed towards Earth except that this one

  • is headed, excuse me

  • there's a whole set of asteroids that cross Earth's orbit

  • that alone is not a problem. You cross the street all the time

  • but at different times than trucks drive by, OK

  • so the issue is

  • are you crossing the street, when the truck is driving there at the same moment

  • that simultaneity is what matters

  • Apophis when you ran the calculations showed that there was a chance of it hitting us

  • in the year 2036

  • with a close approach in the year 2029 on april 13th

  • a Friday, by the way

  • but here's what's significant about that.

  • we've had close approaches before

  • but none this close

  • this is the size of the Rose Bowl and on April 13th, 2029

  • it'll come close enough to Earth to dip below our orbiting communications satellites

  • Do you think 2.5% is a big number, for that asteroid to come to Earth?

  • No, right now the best estimates are seven in a million that it will hit us

  • in 2036

  • and if it does, it will likely hit the Pacific Ocean

  • plunge into a depth of three miles

  • explode, cavitate the ocean send waves of tsunamis

  • the first one from the impact

  • the second one because the water splashing back into the cavity

  • goes high into the air, drops back down and sends another pulse

  • this will go on about forty times

  • there will be multiple tsunamis, I was just on the Santa Monica beach

  • two nights ago, because Santa Monica

  • is the first city to get hit

  • because it's

  • it's the bee-line right up from Santa Monica 600 km into the Pacific

  • five-story tall tsunami would take out the entire west coast of the United States

  • but nobody has to die

  • because we know this well in advance

  • but i think two people will die

  • the stupid surfer who wants to surf that tsunami

  • you know, we know people like this, right? you know, you see them!

  • And you know who else of course, the

  • weatherman who wants to bring the camera guy closer

  • "Can you see the waves hitting the shore?"

  • OK, take him out too. we don't need either one of them.

  • That would make a great James Cameron movie.

  • Ah, yes.

  • Tonight there's a wolf moon can you explain what that means?

  • "What's a wolf moon?" OK, each full moon of the year has a name

  • and there are regional variations among those names

  • and the wolf moon

  • it's when it's snowing

  • and the wolves howl

  • You can see the wolf

  • in the light of the moon because the whole landscape is white

  • and the wolf doesn't.. the wolves don't turn white

  • so you can see them against this and

  • so depending on where if you live in a region where there are wolves

  • that would be what you'd call it other full moon names you've heard of

  • the harvest moon is one of them

  • the honey moon is one

  • that's the moon that's in June. The honeymoon

  • because that moon actually never gets very high in the sky

  • and it's amber the entire time it takes on the color of honey

  • and it's call the honeymoon and you get married in june -- that's where we get the name "honeymoon"

  • Anyone over here? No?

  • Yes sir

  • Uhm, the I think, yeah, in astronomy probably dark energy was sort of a real game changer

  • about 10 years ago, the discovery that the expansion of the universe is speeding up

  • If there's a game changer in the next 20 years

  • What is it?

  • The question is dark energy

  • he said ten years ago was like a game changer -- can I foresee any game changers

  • on the horizon?

  • Well, turns out dark energy

  • was not as much of a game changer as you might think

  • because that .. we already had a slot for it in Einstein's equations

  • we already had a placeholder no one had ever measured

  • it before so we just assumed it was zero and got on with life

  • the moment it was discovered

  • we said, hey

  • now we can stick it in the equation it was like whoa,

  • its presence in the equation shows that there's this force

  • there's this pressure operating against the action of gravity making the universe

  • accelerate in its expansion

  • and that's extraordinary because it means the day will come

  • when these galaxies that Hubble discovered

  • will expand

  • will move away from us

  • with such speed

  • that they will disappear beyond our horizon

  • and the total known universe at that time

  • will only be the Milky Way

  • restoring the state of mind of our universe that existed before 1920

  • that's a spooky time, we'll have to hand down the annals of cosmology

  • from previous centuries

  • to hear about the galaxies that were once

  • in the night sky

  • so game changers going forward: if we discover

  • the dark matter particle

  • that'd be kinda cool

  • if we ... if dark energy, and dark matter, cause we don't know what's causing either one

  • of them but we measured them so

  • they are real in their action on the universe

  • we just don't know what it is

  • as distinct from the ether a hundred years ago we never measured it

  • we just assumed it was there there was no data, it was just

  • dark matter, dark energy, we could call it "Fred" and "Wilma"

  • don't think it's matter or energy we don't know what it is

  • don't let the name fool you

  • I'll for henceforth call it "Fred" and "Wilma"

  • So, "Fred" and "Wilma"

  • these two things

  • it may be

  • a game changer once we figure out what it is

  • it's a new particle

  • that then we can exploit to our benefit in the same way our

  • understanding of quantum physics

  • enabled us to exploit the behavior of atoms and nuclei

  • to our benefit so a new kind of physics would transform how we live

  • that's one way I think it might go

  • [???]

  • Will Pluto not only be humiliated by Neil deGrasse Tyson

  • That's not the word she said she didn't say that word

  • Excised from

  • from the family of planets

  • Neil was on the group

  • that gave the recommendation

  • that Pluto be demoted, correct?

  • We, uh, we..

  • we thought differently about

  • Pluto's identity than Pluto did

  • and other supporters of it.

  • we just grouped it with other icy bodies in the outer solar system

  • that at the time

  • were being discovered

  • you know, don't shoot the messenger

  • Pluto was alone for sixty-five years

  • and so you can't have a category of one

  • that doesn't work in science, you need a few things to make a category

  • it was in a category it was a planet

  • well yeah. My very elegant mother just sat upon nine porcupines

  • Now she just sits upon nine it doesn't make any sense

  • Yeah, it doesn't make any sense

  • Where's the porcupine?

  • If she's that elegant, she wouldn't have sat on a porcupine, I don't think

  • but, so once we found other icy bodies we .. what we did is group them together

  • we said

  • Pluto, we found family for you

  • in fact, we think you're happier there cause now you're one of the biggest icy bodies

  • Rather than a pipsqueak planet

  • You sent Pluto to a farm upstate to run and chase rabbits, is what you did

  • It's much happier there, kids

  • It's happier there and I didn't do this alone

  • is there a super-giant beyond pluto that that pulls comets in? is there

  • is there a chance there is something out there that's drawing

  • There was a hypothetical star

  • which is related a little bit to what led to this

  • invention of this 2012 , the 2012 brown dwarf (the brown dwarf that you won't talk about)

  • there was a come down to the bunker, too

  • There was a suggestion that there was a companion star to the sun

  • provisionally called "nemesis"

  • that had this elonged orbit that would

  • jostle comets in the outer solar system

  • and send them raining down on Earth

  • creating mass extinctions

  • accounting for the extinction

  • episodes in the fossil record

  • but.. it was an interesting hypothesis that was never supported by data

  • and so when you're not supported by data you discard the hypothesis

  • that's how science works

  • you don't believe something just because you want to

  • or think something's true just because it feels good. at some point

  • you've gotta confront the data so getting back to the point

  • You've never been in politics

  • so getting back to the point

  • the recognition that Pluto's made half-ice

  • and ice evaporates

  • so won't Pluto one day disappear? no, Pluto's too far away from the sun

  • for that to ever meaningfully evaporate and disappear completely

  • What was the point of the Large Hadron Collider?

  • "what was the plan", did you say? "The point?" "what was the point?" he speaks in past tense

  • as though we're done with it

  • well we just turned on the switch

  • the Large Hadron Collider in Switzerland

  • the point of the the Large Hadron Collider was to embarrass America

  • to make us feel bad that we didn't have our collider built

  • back in the 1980s when it was first funded

  • That's the whole point of the Large Hadron Collider

  • It's Europe saying "Ha! Gotcha this time!"

  • now apart from that ego bit,

  • uh, it's to probe nature

  • on levels of energy never before seen

  • and right now it's hard

  • practically impossible to discover a new law of physics on your tabletop

  • we've been there

  • we've done that

  • and almost

  • the entire history of physics

  • is: go to the edges,

  • of your points of exploration and then take a step beyond that

  • you're bound to discover something new

  • it's like one climbing the next mountain, crossing the next valley

  • so the large hadron collider the energy inside that particle accelerator

  • will exceed the energy of all the accelerators

  • that have ever been built before

  • probing nature as never previously imagined

  • What is the Higg's boson?

  • Higg's boson

  • that's a particle

  • proposed

  • that you can think of it as a kind of uh...

  • it's like a

  • think of it like

  • molasses

  • well, ok, not molasses, uhm

  • it's a field through which all particles move,

  • and the interaction of those particles with that field

  • endows them

  • with the mass

  • that we measure for them

  • it is granting them

  • the property of mass

  • we have yet to find this particle but if we do .. so mass is not explained presently

  • That's correct, we just measure.. we don't know why

  • we get fat

  • we don't know why something has mass right now (correct)

  • and so we

  • now, may I ask you something if you have.. if you build

  • let's say you build an equation this way you've got an equation over here, you've built it

  • and it's a house, ok?

  • and you've got another equation over here that works, it's another house

  • but in your mind you think

  • these two houses are actually probably shoudl be one house

  • you invent something that fits into the shape between the two houses, right?

  • (yes) [??]

  • Ok, there's something in universe that is the shape

  • of the space between these two houses (yes)

  • does that necessarily mean that thing is there

  • the history has shown that

  • almost every time

  • we propose something that connects one house to another .. if those two houses

  • themselves .. work

  • there's something in between them connecting the two

  • for example

  • for example

  • the 1930s, we had this experiment .. 1930s

  • quantum physics is in place

  • we start probing the atom

  • we find out there's an atomic reaction, a nuclear reaction

  • where there's some missing

  • energy

  • we account for all of it and there's something missing

  • there's this much energy here and then it's missing here

  • and we swear we've accounted for everything

  • Fermi comes up (a famous physicist) said

  • I bet there's a particle

  • that came out of that reaction

  • that escaped with the energy before you got a chance to measure it

  • E=mc^2

  • That would've endowded that particle with it's energy to do so.. the mass to do so

  • E=mc^2 is in every one of these

  • it's all over the place

  • it's writ with E=mc^2 the point is

  • he hypothesized a particle

  • gave it the properties that is would have to have

  • to account for what was seen

  • that's your conduit between the two houses

  • then he said, it's gotta have this much energy

  • and it's gotta be pretty hard to detect because we surrounded this in lead

  • and it went straight through the lead

  • I'm gonna propose a particle that's hard to detect

  • and it's gotta be little, cause there's not that much mass, and it has no charge

  • so it's neutral

  • so, he called them neutrinos "little neutral ones"

  • he hypothesized, he said let's look for them

  • twenty years later they were found, neutrinos

  • and now we [kept?] them coming out of these reactions

  • he built the porch

  • the walkway between the two houses

  • practically every time you have two working

  • understandings of the world

  • at they have to coexist in the same universe there's something that's going to connect them

  • it's like

  • electricity and magnetism

  • previously discovered as separate things

  • until Faraday and Maxwell said hey, wait a minute

  • this works, and that works

  • and they kinda smell like each other a little, maybe they're the same thing

  • so a whole theory came out

  • to put the two together, and it is the theory of electromagnetism

  • you know this word, you just take it as a single word, but those used to be separate concepts

  • so, we're going good with this

  • we're on a roll here

  • so why not continue

  • Yes, right there

  • Do parallel universes exist?

  • Do parallel universes exist? we don't know,

  • uhm

  • parallel universes are losing favor to the multiverse

  • we have some cogent theoretical

  • expectations

  • that our universe might be just one of many

  • spawned from this, sort of, this hyper-dimensional

  • medium which we'll call the multiverse there's no data to support it

  • but we have good theoretical

  • premise

  • to think that it's there and we have philosophical precedent

  • we used to think Earth was special and

  • unique. It wasn't, we got 8 .. 9 .. 8 planets

  • we thought the Sun was special

  • it's one of a hundred billion suns, the galaxy's special, no there's a hundred billion galaxies

  • we have one universe

  • or do we?

  • The track record said

  • why should there only be one?

  • be open to the possibility

  • that you don't live in the majority [looking?] universe that's out there

  • Would a separate universe .. when you say "different universe"

  • slightly different laws of physics which (that's what I'm asking)

  • oh this is the fun part

  • because if you find, if you manage to get a portal to another universe

  • don't be the first one to volunteer to go through

  • because your atoms are working in this universe

  • if a slightly different law of physics.. you could implode, explode

  • come out with three heads who knows?

  • There's a different exchange rate over there Yes

  • someone .. let's go in the back

  • in the middle of

  • and I think.. you have a white sweater on

  • Is it possible to tunnel through a black hole, like, quantum mechanically speaking?

  • Can a black hole be used to travel how about that, can we say that? No

  • no, it's a little different

  • Steve, get with the program tunnel through a black hole

  • (yes, quantum mechanically ) as if it creates a tunnel, in space or time?

  • quantum mechanically is what she said

  • quantum mechanically, can you tunnel through a black hole?

  • I'm not gonna try to interpret this one

  • Well I have to ask, did you want to land someplace else when you're done

  • or are you content with being dead when it's over?

  • I need to know before I answer

  • I guess it's ok if I die

  • It's ok if you die

  • For science Stephen Hawking showed just recently

  • that, and for me this is kinda spooky/amazing

  • that black holes

  • remember everything that they have ever eaten

  • which means, it's not a tunnel to anywhere

  • everything that it ate is sitting there at the singularity at its center

  • now the spooky part, that's not the spooky part

  • the spooky part is

  • Stephen Hawking showed forty years ago

  • that black holes can actually evaporate

  • the matter that's within a black hole

  • can

  • rise up out of the gravitational field that surrounds it

  • and spontaneously birth a pair of particles

  • that's just E=mc^2 doing it's thing

  • E=mc^2

  • the gravity field has high energy density

  • out of that pops particles

  • and those particles escape

  • taking

  • matter away from the black hole

  • from the

  • from the gravity field of the black hole

  • doesn't that fly in the face of.. how we think of a black hole

  • in a black hole, gone forever

  • because nothing escapes, because nothing has

  • nothing can surpass the energy needed to go faster than the speed of light

  • except quantum mechanics

  • quantum physics from the 1920s gets you out of that problem

  • that's a classical understanding of black holes you layer quantum mechanics on it

  • weird stuff happens

  • completely legitimately weird stuff happens

  • so you birth these particles outside the thing now here's what happens

  • That sounds like

  • science is making magical exceptions for itself

  • quantum physics

  • is kind of magic

  • because none of it issues forth from your common sense

  • particles pop in and out of existence

  • one time it's a wave, the next time it's a particle, and it interacts with itself

  • and you measure here but it shows up there

  • if we were forged in that world

  • then all that would be common sense

  • And E=mc^2 would be a daily phenomenon

  • you wouldn't need Einstein to figure it out

  • You'd be learning it in elementary school

  • but that is a foreign universe to us

  • as to what goes on there, you are prone to say: that doesn't make sense

  • you know something -- it's of

  • no obligation to make sense to you because your senses

  • didn't come out of that universe

  • out of that universe of tiny particles we don't live there

  • if you let something go and it drops you say "that makes sense"

  • if you let something go and it goes up you say "that doesn't make sense"

  • in quantum world, that happens all the time

  • it would make sense in the quantum world

  • so I submit to you

  • that if I take your body and dump it into a black hole, what Stephen Hawking showed

  • is that

  • all the particles that went into the black hole let's say

  • it's Stephen Colbert black hole ok, no other contaminating bodies

  • but your atoms in the center of this black hole

  • and i wait around and out here

  • in the gravity field

  • particles pop into existence

  • and I check, make a check, how many protons

  • how many neutrons

  • how many electrons, how many neutrinos

  • by the time this black hole has evaporated

  • it would have been every single particle that you were

  • having fallen in in the first place

  • extracted out of the energy field of the black hole so it remembers who you

  • were, even out in the gravitational field

  • that's spooky to me

  • Is the black hole now gone? gone

  • disa .. pops out of existence

  • evaporated. it takes .. by the way

  • it takes several trillion years for that

  • so don't wait around for it

  • that young man right there

  • How do you figure all this out?

  • it's an excellent question yeah, it's a good one

  • Isaac Newton

  • did it all by himself

  • he was like, really, really

  • really smart

  • a quick Isaac Newton story

  • he discovered the laws of motion, the laws of gravity

  • shows that planets don't orbit in circles as Copernicus had thought

  • but in slightly flattened circles we call ellipses

  • and

  • and some friend of his said, "Ike, why ...",

  • [ thought maybe he'd be called Ike ??]

  • "why that shape, and not some other shape?"

  • he couldn't answer that question, he said "I'll get back to you"

  • goes home for two months, comes back, here's why it's that shape

  • the conic section that cuts through the thing

  • and said well how did you figure that out he said, well

  • i had to invent integral and differential calculus to figure it out

  • so some people invent their own

  • tools and methods

  • to discover the world

  • most people

  • learn the tools from someone else

  • and then apply them to make incremental changes some people make huge changes

  • like Isaac Newton and

  • and and and

  • Einstein and others

  • Isaac Newton once said, "if i can see farther than others

  • it's because I've stood on the shoulders of giants

  • who have come before me"

  • But I've read Issac Newton

  • and his stuff makes the hair .. if I had hair there

  • rise up on the back of my neck how plugged-in he was to the universe

  • and i'm saying to myself that quote cannot have possibly have been honest

  • what it really meant if [i could re-give] that quote to him

  • If I can see farther than others it's because i'm standing

  • among midgets, that's why he could see farther than everybody else

  • in the case of Isaac Newton

  • I'm afraid we only have time for one more question, yes sir

  • Actually that was a great segue to my question

  • we organized this all for your question

  • earlier in the evening you brought up

  • the ideas of scientific literacy and technology [???] management

  • I'd like to hear your opinions of where the policy needs to go to make a positive impact in that area

  • alright Neil could you repeat that for everybody

  • the question is

  • we were talking earlier about scientific literacy and our approach toward science

  • as a nation

  • in your opinion and you you serve on science advisory panels

  • where do you think

  • we need to go as a nation what do we need to do to increase of scientific literacy

  • I'll answer it two-pronged

  • one is: what do you do with your kids?

  • and kids

  • need to be able to explore freely

  • and if you look at most households

  • they're not designed for that

  • they're designed to have the kid not explore

  • the kid come into your kitchen and pulls out the pots and pans

  • and starts banging on them, what's the first thing you do as a parent?

  • stop that, you're getting the dishes dirty

  • yet these are experiments in acoustics

  • that's what that is

  • okay

  • whatever the kid is doing, if it has the chance of breaking something

  • you're gonna to tell them to not do it

  • without thinking that that's the consequence of an experiment

  • that they are conducting

  • and every time the kid wants to do something provided it doesn't kill them

  • it's an experiment

  • let it run its course

  • even if it makes something messy

  • you agreed to have a kid in the first place, fine, clean up after them

  • when they're old enough

  • Because it's those seeds of curiosity

  • that is the foundation

  • of what it is to become a scientist

  • i don't want everybody to be a scientist that'd be a boring world. i want the poets

  • and i want

  • musicians

  • we need that and I don't have a ...

  • but I'm talking about promoting science literacy

  • and so the first step

  • for the parents is to get out of the way

  • allow the child to explore

  • they start playing in the mud "don't do that in the mud I just cleaned those pants"

  • you're getting in the way of another experiment

  • they start plucking the petals off the flowers you just bought

  • from the florist

  • and you say "stop that I just paid $10 for the flowers"?

  • had you let that continue they'd find in the middle the stamen, and the pistil

  • and they'd learn something about the flower

  • for 10 bucks that's cheap

  • Derek Bok, one-time president of Harvard once said

  • if you think

  • education is expensive, try the cost of ignorance

  • and so

  • that's so.. that's gotta start at home. in the schools,

  • I don't have a problem with the fact memorizing

  • but don't equate that with what it is to be wise

  • or

  • what it is to be smart

  • smart should be some combination

  • of that yes, but also

  • what is your lens on the world? how do you figure things out?

  • and you promote that by stimulating curiosity

  • and I don't see enough stimulated curiosity

  • in this world. this is a famous school right here, I saw the banner in the opening

  • corridors, so you probably don't have that problem here

  • all right, but the whole world is not educated in this building

  • so a lot of change would need to happen in that regard

  • now getting back to policy

  • I've tried

  • you do a simple Google like "youtube and tyson" well, put "Neil" so you don't get "Mike", all right

  • dining on someone's ear

  • half of what ends up thrown onto youtube

  • are talks I've given

  • where I am trying to convince people

  • not only the public

  • but lawmakers

  • and people in power that

  • investing in the frontier of science

  • however remote it may seem in

  • its relevance to what you're doing today is

  • a way of stockpiling the seed corns of future harvests of this nation

  • and those seed corns what they do is

  • whether or not you know it today

  • advancing a frontier history has shown has advanced the culture

  • ever since the industrial revolution got underway

  • and we can speak more

  • hegemonistically about it that anyone who has embraced

  • the powers of technology has enjoyed economic wealth the likes of which the

  • world has never seen attendant with

  • strength strength of security

  • and so people say today

  • they'll say suppose the next attack

  • terrorist attack is like a chemical attack

  • do you call out the marines, or do you get your best chemists

  • to figure out what to do about that

  • there's a point where your weapons are not as useful

  • as the brain of the scientist who you could bring to bear on the problem

  • and so

  • i see science and technology and creative investments in it

  • as the most significant

  • infusion

  • to our economy that could possibly be conceived

  • the problem is, it's not going to boost the economy next quarter

  • it's got a time horizon longer than most people have the patience for, and most

  • politicians have the re-election cycle to be tolerant of

  • so what we need is a longer view

  • on those investments

  • I don't want to have to have NASA going hat-in-hand trying to get money to stimulate

  • the frontier of cosmic discovery

  • and that frontier now involves biologists in the search for life

  • chemists, in understanding the soils of Mars

  • uh, aerospace engineers. you know what I don't want to do, I don't want to

  • stand in front of eighth-graders and say "who wants to be an aerospace engineer

  • so you can design an airplane that's

  • fifteen percent more fuel efficient than the one your father flew?"

  • That's not going to get them but if I say

  • who wants to be an engineer

  • and design an airfoil that will fly in the rarified atmosphere of Mars

  • I'm going to get the best students in the class and you know it

  • because that's an exciting project for smart people work on motivated people to work on

  • and when you have them, they invent stuff they discover things, they transform the

  • culture in which we live, on a time horizon that is not be easy to just

  • tell someone

  • in a one-sentence sound bite

  • and what i want is a level of science and cultural literacy

  • that will allow the public

  • to be able to think beyond the election cycle

  • to think for themselves and say this is a good investment

  • how many times have you heard people say if you're not among us here

  • why are we spending money up there when we have the problems down here.

  • Have you ever asked how much money were spending up there?

  • ask that question

  • you know what the answer is?

  • I've asked people how much money do you think we're spending there

  • here's your tax dollar

  • how much is it? ten percent? fifteen percent? those are the kinds of answers I get

  • you know how much is getting spent the rovers, the space station, the

  • the space shuttles, all the launch vehicles all the NASA centers, is 6-10ths

  • of one penny

  • on your tax dollar

  • 6-10ths of one penny pays for it all

  • and you're telling me, why are we spending there [not] down here

  • if you need that money to solve these problems, you got some other problems going on OK?

  • That's a whole other problem with society

  • so

  • I'm sorry, I'm spitting I'm getting all ...

  • so my point is I think the greatest

  • the greatest

  • need

  • is to be able to have the foresight necessary

  • to make investments on the frontier of science

  • even if at the time you make those investments

  • you cannot figure out how that might

  • make you rich tomorrow

  • Michael Faraday in 1840s was the first one to pass a wire

  • through a magnetic field

  • and it made a little meter

  • tick on .. it moved uh, a meter

  • he hooked up to it

  • [now this guy?] you do this, and this happens. That's kinda cool

  • if you're nerdy .. to a nerd that's a cool thing right you do this and this happens

  • and so what was happening is

  • it induced a current through the wire

  • he showed his colleagues, it looked like just kind of a curiosity, a toy

  • showed it to Parliment, they say why? this is what we're funding?

  • we're funding this toy?

  • this may be apocryphal but it is said of Faraday

  • in response to this inquiry said

  • because they asked, what value is this to the british empire

  • and to the King he said i don't know

  • without value it is today

  • but I know, one day, you're going to tax it

  • and in fact that is the foundation of how all electricity is made today

  • and it would take another sixty years before electricity would come to homes

  • but who could've known it at the time?

  • I don't want to be left behind

  • I will not leave you behind

  • last thing I'll say

  • the biggest news story last year to me

  • was not the methane, uh, flatulence

  • the biggest news story

  • happened december 22nd, something like that

  • I forgot what day

  • a press release comes out

  • Russia says

  • they want to send a mission to deflect Apophis

  • the killer asteroid (oh yeah)

  • by the way, I said if that hits it's gonna hit the Pacific

  • which affects us

  • ok, Russia says

  • we're gonna launch a mission

  • we're gonna start designing it now and we're gonna fund it. oh by the way

  • the United States is welcome to join us and people say oh that's nice

  • a little international thing, I'm saying wait a minute

  • something's wrong here

  • aren't we the ones

  • who are supposed to be starting missions and then advising other people to join us?

  • isn't that how it's been?

  • so that was a sign

  • one of many

  • that our significance and meaning on the world stage

  • is fading

  • and it's fading fast

  • and it's not a cliff

  • it's just a fade

  • and the day will come, where the rest of the world just makes their own decisions

  • about the future of their own space exploration and technologies

  • and we're sitting back saying

  • Hi fellas, can we join along

  • Neil

  • we already proved

  • we can deflect asteroids in the movie "Armageddon"

  • so there's our fantasy: we don't do it in the real [world], we do it on the silver screen

  • and we're happy about that

  • maybe we gotta fix that disconnect. last question

  • why is there something

  • instead of nothing?

  • ten words or less

  • just because

  • So, I gotta do this in haiku then

  • ok, five seven five

  • words that make questions

  • may not be questions

  • at all

  • I am well-rebuked

  • Neil deGrasse Tyson, it is an honor to have you here and an honor always to talk to you

  • please, come on get up for Neil deGrasse Tyson

  • Uhm, Dr. Tyson is going to be down here he will signing books until 9:30 so

  • if you'd like to come down and have then signed, feel free

  • For the rest of you, thank you all for coming and get home safe

Uhm, for those of you who may not know the Academy forum
