And quite appropriately, I'm being driven by Henry from minute physics. I'm sure most of you already watches videos, but Henry's gonna drive me there, drop me off, and then I'm gonna have a look around and show you some really cool stuff with the settlement. I see these signs here, here, Berkeley. They have parking spaces reserved just for Nobel Laureates. So how do you prove your Nobel laureate you have to Do you have to put your medal on the dashboard? What's it? What's it called you? Don't you put your metal to the pedal to the metal? What do you think, Daddy? Go. I'm gonna put you on the spot here. Should science buildings look like this, Or should they be the modern glass ones? I like him like this. It's not, isn't it? That's why, but it's not efficient. Probably these days. Let's go and have a look at it. Let's go have a look like that. Look actually says 23 24 and Seaboard claims, then it was a dark and stormy night of February 21 when they did the chemistry. I'm out of breath, so they still probably had to do some further experiments to substantiate it. A nice suppose. That's why they put the 23rd 4th on here. But he clearly says it was a dark and stormy night, February 21st late at night. All good experiments happen later. Light when you're ready to quit. Is that just bad luck? Do you think there's a reason for that? There's a reason for that. It's when you think you just can't go on and you do the little extra experiment, a little extra thing that's necessary to pin it down. And I found that many times. Professor, this lab is obviously a historic site. We can see from what's on the wall here. Is it still used for science, or is it like a museum? Now? I think this answers a question that says Newman Lab research on Micro Chemical Systems. What do you think about its Berkeley? Don't rest on past florals. I had always wanted to look for heavier elements because when I was a little Salma LS with big us Thermo nuclear test was had just been tested in the South Pacific. I had been a toll bridge sooner and came to Los Alamos following my husband. And they lost my clearance between old bridge and low Salome ALS. So I missed being a co discoverer of Einstein, Ayman Fermi. Um, and I've never, ever gotten over it. So you'd be stepped on bigger co discoverer of those elements because of an administrative mistake. Exactly in those days, they didn't track those things with computers. And one thing and another well, way would irradiate samples in the cyclotron down there and then take the sample out, take the from radiation area, put it in a lead, pig, put it in the car, and then drive all the way up here, help it for breakfast and bring it into our laboratories in the building right behind you. What was the hurry? Why not just do it leisurely after lunch? Because we wanted to look at things that had minute, half lives are multiple minutes. That was about as good as we could do with that method. Why didn't you just put the chemistry lab closer to the cyclotron? Well, later on, we did. That's a much better idea. You should have employed May. I would have been brilliant. Well, we had to get him to let us do that to have the space. And I think maybe I told you when we were down there, we put a little mezzanine right there above cyclotron. And then way could run a helium jet transfer to take things into our little mezzanine hood. What's a lead pig lead? Pig is a container made of lead with the hole in the middle of it that you dropped the sample in and then put a lid on it and tell you the truth, I've asked person after person. I have no idea why they were called pigs. So this'll is like one of the most sophisticated, important laboratories in the world. And you were making new elements, and then you're putting them in a car and rushing them up the hill like a like a car chase. Well, I was not a party to the discover any new elements, but these were isotope new isotopes. We were looking for same idea, and they also did the same thing for some of the elements who used to drive the car. Who was the getaway driver? I was trying to remember? I think maybe algae or so sometimes on. And maybe sometimes Greg Show pity who was a graduate student? What's this? You've come to show me where we standing on the hill above and opposite the U. S. University of California campus. This is the Lawrence Hall of Science. It's part of, you know, Ghostie. It's, ah, sort of museum science reason for Children. They come in here with special, but this is not just something you look at, but its hands on you play with it. This is a facsimile of the first iron Secretary built by Ernest all under Lawrence. He got the Nobel Prize for that, and it's this acceleration of irons by alternating magnetic fields. Makes it possible to get fast irons to do these nuclear bombardments and through that mechanism, creating new elements on that's something that's, uh, Glen. Seaborg was deeply involved in Professor as a as a modern scientist that now is still working in an age where we have Large Hadron Collider is and some really large accelerators. How do you feel about objects like this? Does it still excite you and inspire your Does this seem small to you? No. On the contrary, I always go back to the origins. Always go back to the original. If you understand relativity, You read Einstein's paper relativity, Of course. The things that come out of the critical but going back to see how this arose from nothing as opposed to the sort of growth of the enormously powerful things today that really probe nature does extreme this'll. CE is exciting, scientifically creative, wise and just as an emotional thing. It's absolutely wonderful. Seaborg in later days didn't like to drive all that well because he had arthritis so badly. And so he would ask if I'd drive him to campus. Yeah, because you got to have a Nobel Prize.
