Hilbert - Enjoy mathematics with Keyboard.
Hilbert makes it possible to enjoy mathematics on PC without losing the feeling that you can get from using Pen and Paper. TeX provides us high-quality mathematical formulae, but sometimes we want to execute them. Hilbert will allow you to compile codes into TeX. You can execute and get awesome formulae using Hilbert. You will be able to use Hilbert within any widely used languages like Ruby, Hask

The SciRuby Manifesto Ruby is a great choice for scientific computing and data visualization. Even though other languages have more libraries - and we can not do without them - Ruby has its own place in Science and it is always a pleasure to write software in Ruby. But there is only one way to find out and that is by writing code! Sometimes when a solution of sugar and water becomes super-saturate
