Elasticity

It's waterproof.

You can use this stored elastic energy to move blood. You can use this for movement energy.

A rubber ball bounces because it is elastic.

Beyond drag, lift and stretch there are many other properties we could simulate.

I would even throw up some numbers. Lets say this is 100 and maybe up here its 80. Its got to be a little bit lower.

This material has no give.

Today it's less than 50 cents a day.

So lets draw that in here. There is a little bit of elastic energy left.

These are things we never could have imagined a few years ago.

But I wouldn't have you think that I don't like the place on the right, which I quite do.

Modulus

Where did you learn to count?

And those little gray lines are the connections that connect them together.

And that's true of any sample statistic.

All the oppression of the poor and the powerless... of women.

He said bombs.

Correlation

Extinction

Cooling factor

Example Benjamin Robins's extraordinary application of Newtonian physics to ballistics.

So I can just rewrite that as A so now A is not a function anymore, it's just a number A times the second derivative of y, with respect to x, plus B times the first derivative, plus C times y.

That elastic energy would be something like that. It would actually take up a chunk of that pressure energy.

Next I want to focus for a little while on the notion of a clustering coefficient.

So now my pressure is on top and the volume is down below. And if you have it like this, pressure over volume, we actually call that elastance .

What are the emotions that can be measured?

Five.

This is supposed to be a constant

So there's a fair amount of interconnection between a node's neighbors.

So just getting it correct to a couple of digits is probably sufficient.

2nd derivative r squared.

What's the connection?

Erika and you, and your little sexual indiscretions.

So instead of reporting just the point estimate, what is the mean, what is the correlation, what is the regression coefficient.

High explosive incendiary.

Now it's about eighteen.

So we'd like to have a way of getting a pretty good answer in time a lot less than this.

We'll come back to that again in multiple regression, and in lecture nine in R. And then, the importance of this distinction between unstandardi zed and standardized regression coefficients.
