In my last blog post, we looked at various examples of electrostatic potentials and magnetostatic fields. We ended with a rectangular current loop. Electrostatic and magnetostatic potentials for squares, cubes, and cuboids typically contain only elementary functions, but the expressions themselves are often quite large compared with simple systems with radial symmetry. In the following, we will discuss some 3D charge configurations that have sharp edges. More »

Step-by-step solutions, one of the most popular features for mathematics in Wolfram|Alpha, has just received a dramatic expansion in its functionality! With our new interface, you now have the ability to walk through all of our Step-by-step solutions at your own pace, revealing only one step at a time. Some of our programs will offer to guide you with hints when walking through solutions. And for common math problems, we can even show multiple ways to find the solutions. More »

If you’re a chemist, a student, a mad scientist bent on destroying the earth for irrational reasons, an enlightened scientist bent on saving the population from the mad one, or as understandably enthused about isotopes and radiation as we are at Wolfram, then you’ll love the new Wolfram Isotopes Reference App and Wolfram Radiation Protection Reference App. Released for $4.99 and $9.99, respectively, for the iPod touch, iPhone, iPad, and PC, the apps are arguably the most comprehensive set of tools for the topics so far.

Recently we released the new Wolfram Geography Course Assistant App for iPhone, iPod touch, iPad, and PCs. Whether you’re studying for an exam or merely a geography nerd like me, there’s no better way to get either a general overview of the planet we all share or a really in-depth analysis of specific datasets. You can study Earth’s physical geography, geology and climate,  political boundaries, demographics, economics, and social statistics. It might be the best $4.99 you’ve ever spent, and to prove it, allow me to attempt a persuasive argument. More »

Most of the new features we announce on this blog are large-scale projects where we add a huge chunk of data to Wolfram|Alpha all at once. But there are always dozens of background projects going on at any given time—including a seemingly never-ending effort to expand our database of information on private companies.
