The greatest thing since sliced bread.

Enjoy! We’re starting with this post a brand new column “Handy Math” – it’s dedicated to Professor Feynman of course.

PS Yes dear readers, watch for another new column later in the week.

We promised this week we’d post a multiple pendulums app. Sorry, I’m not sure we can keep our promise. We have many more. A quick search on one of our iDevices listed the following. Enjoy! Feel free to use the comments to suggest more.

We all have heard about how important is qualitative analysis of, e.g., differential equations, lest the numerical solution leads us astray. But have we heard any lecture on situations which defy calculus, and yet can be tackled by a modern computer? Of course, the Monte Carlo method. Anything else? If you can’t come up with anything else, read the book by Paul Nahin for a lot more.

This software is not free, in fact it’s quite expensive. However, it’s simply the best when it comes to polyhedra and polytopes. Amazing.

We are sorry to say that the Geometry Center is now closed, and has been for a few years. Pester your congressperson.
