What is it called? |
I've heard of some materials that when you squeeze them in one
direction, they are squeezed in all directions. I'm wondering if and of
you know what that's called.

Yes. It is called money. ;-)

I'm serious. :P
These exotic materials are supposed to have a negative index of some
sort, but I forgot the word for that too!

Let me rephrase the question.
Easticity deals with how much X shrinks when Y grows and vice versa. It
has a negative elasticity index. Some materials have X grow when Y
grows and likewise for shrinking. It has a positive elasticity index.
What are the latter materials called? I think there's also a word for
the former material, so what's that called?

Poisson's Ratio perhaps?
Is this the kind of thing you are thinking of. . .
