I want to thank the organizers for inviting me to this.

I'm a mathematician, and the closest I get would be CIDCOM,

And I have this incredibly pretentious title.

So sort of think of this as a quick preview of the videos.

not enough time to give them all the credit they deserve.

So what I'm interested in is these sort of major transitions

But they're also changes in architecture,

and you see increases in complexity and elaboration

Unfortunately, those are the four most confused subjects

And engineers know a lot about these things,

So I'm going to focus on two parts of this.

Of course, you're interested at this stuff at the top.

But I'm going to kind of use bipedalism, that transition,

If we hadn't done that, none of the rest would have happened,

they're all crucial, but that one's particularly crucial.

Well, my main way of doing it is with math.

We'll focus on trying to look at some diverse domains, so not

just networking, but like I said, bipedalism and our brains

And so one of the objectives of my research

is to try to get this to be not a whole nine

And that's the framework to try to do this,

And again, lots of details in the videos.

So now, I'm very different from this community.

Maybe only one letter different, but that

have different priorities but the same interests.

And by deterministic I just mean in the way

I focus on not average behavior, but kind of what

And so in bipedalism, one of the most important things

is a trade-off between robustness and efficiency.

We'd like to be in the lower left hand corner.

And if you compare us with chimps, for example,

at distance running we're about four times

as efficient as they are, and that's really substantial.

And if you've got a bicycle, you get another factor

and so that's the trade-off we see in adopting bipedalism.

And so what I want to do is think about these kinds

We'd like to be cheap, we'd like to be robust.

Now the cardiovascular physiology part of it

We have a very upgraded cardiovascular system

If you want to read about that, that's a recent paper.

And I have some, again, videos online on this physiology.

We're going to worry about the balance part of it,

and not worry about efficiency, but really robustness.

And ideally, again, we'd be cheap, fast, flexible,

Again, I'm going to ignore the cheap dimension.

PowerPoint only lets you really draw things in two dimensions,

So again, we'd like to be fast, flexible, and accurate,

So what I want to talk about is the trade-off

on a very simplified view of what our brains do,
