Ian Stewart has a new book out.

- Professor Stewart's Cabinet of Mathematical Curiosities By Ian Stewart. amazon

Read 1/3 of his Flatterland amazon in ≈2002.

See also: FLATLAND: A Romance of Many Dimensions, and Flatland: A Introduction (by Xah Lee) for many subsequent books and films on Flatland. It is one of my favorite book, say, in top 5, of all books in my life.

Thanks to R Michael Underwood for the tip.

Mathematicians Richard Palais and Hermann Karcher, have released a new version of their math visualization software, the 3DXM. The main change is that it now has button-like interface in place of menus, where each button is a icon of the surface or math subject. This makes it much more attractive, and easier to use. Check it out.

Download at 3DXM.

Note: the new version is for Mac only. For Windows or Linux users, there's always the Java version at the same download location. Though, the Java version has only some 50% of surfaces or other math objects.

A fantastic java applet to draw Voronoi diagram interactively. Very nice.

Math Prizes and Nobel Ignobility. (commentary)

My friend, Richard Palais, co-authored with his son Robert Palais a new book Differential Equations, Mechanics, and Computation. I've been hired to help them update the site. The result is this: ode-math.com. Half of the book is free in PDF files. Also, lots of java applets and animation files are coming.

You can buy the book at Amazon: amazon. However, for some reason, Amazon doesn't have extra copies.

Discovered that there are quite a lot articles in remembrance of Martin Gardner. See bottom of: Martin Gardner (1914 – 2010).
