To many, geek = math && nerd = math. To others school = math && math = calculator. During my stint as a computer science major, the very idea of differential had me running scared back to my calculator. It was a must, and for many a symbol of intellect and power.

At its heart, predicting the supply of water is a math problem—an extremely complicated math problem. The USDA's team chose a platform consisting of open-source development tools from Sun Microsystems, Intland Software and Collab_Net.

If you’re a command line freak, you’ve probably use expr for common math calculations but did you know that the bc command allows you to do similar math calculations and is more powerful when it comes to bigger calculations?

Turning plain data into shiny graphs similar to Visual Thesaurus and Visuwords doesn't only make them look good: it also allows you to visualize connections between different data bits and makes it more fun to explore them. The problem is that creating such graphs can often require three things not all of us have: programming knowledge, time, and money.

Visualize is a jQuery plugin which converts tables to charts & graphs using the HTML 5 canvas tag.

The usage of tables is very important the data is already formatted in a way that is accessible to users browsing the web with a screen reader

I've written quite a bit about using Linux to help educate people. Kig allows you to use various tools to diagram and demonstrate different mathematical concepts.

This opinion piece (PDF) in Notices of the American Mathematical Society, argues that since mathematicians increasingly rely on software in generating their results, we should be increasingly concerned about the use of proprietary math software, since (a) not everyone has access to that software and (b) the code used by that software is usually closed-source, so the algorithms used can’t general

Flickr isn't just for photo sharing and social networking; it's a legitimate business tool. Learn how Perl programmers can use the CPAN Chart modules to create charts and graphs, and the Flickr::Upload module to upload the charts to Flickr.

Whether you're a high school student or just starting out with your college coursework, the free software community has provided a wide range of solutions to make life easier.
