Lots of good stuff in +Plus Magazine #50

As usual, much good math to read about in this issue of Plus. My favorites:

Music from sine waves

A new approach to solving fluid dynamics problems.

Sundaram's sieve for prime numbers.

And just for you, Queen Anne, way too much geometry.

New Dumas novel (mostly) discovered

This old Guardian article from May 2008 talks with Claude Schopp, a Dumas scholar who turned up most of an unknown Dumas novel.

"Imagine that a previously unknown Dickens novel suddenly turned up after gathering dust for more than 130 years. The mere suggestion seems ridiculous. How could a book by one of Britain's best-known 19th-century writers possibly have slipped through the net for so long? Or even at all? Yet that is precisely what happened to Alexandre Dumas's final epic, Le Chevalier de Sainte-Hermine, which was published for the first time in France three years ago and is being published in English this week as The Last Cavalier."
