Has anyone else heard of this website? One of the students in the class for which I'm the GTA found it a few weeks ago, and was showing it to us in class yesterday. It was made by the same guy behind Mathematica:

The professors in the Chemical/Bio Engineering department seemed pretty excited about it.

Some examples of calculations you can do/information you can look up/equations you can graph:

(population of India + population of China)/world population

Viscosity of water at 16 celcius.

Prandtl number of ethanol.

Gravitational pull of Sun.

e^x^x (not only will it graph it, but it'll give you the derivative and other such information).

It's not just math. Type in 'Scrabble' and you get a bunch of anagramming tools. Type in 'poker' and you get tools for probabilities of card draws.

I've used Mathematica a lot in college, and having a lot of the power of Mathematica unleashed to the 'normal' person is amazing, in my opinion.

there already is a thread about this :p

Yup, and guess who started THAT thread [looks at anna-banana]
