What is the big thing in Math

Hi,

I am in biochemistry and I am wondering what people are studying in math these days.  Everything I learned in math class was proven hundreds of years ago.

Okay, if you could leave some examples in layman's terms that would be good.

Thanks.

Lol I'm not sure if there's any current research that could bedescribed at all to someone who only knows calculus, at least that I know of.

It's different from other sciences in that since nothing really gets discarded, you almost have to know everything that's happened in the past to be able understand what's being done in the present. :/
