I would recommend you purchase that book. They are not really my algorithms and I don't want to be accused of copyright infringement. The reason it can't easily be put in a spreadsheet is it is really numerical calculus and the program runs multiple loops (finite steps whereas in calculus the step size is taken to the limit of zero) to develop the performance of a complete blade.

Perry, I tried to do just that this evening but neither Amazon nor B&N stock it, and Bookfinder.com says:

The Books in Print database claims that the book with ISBN "1893639053" is in print. Unfortunately, none of the 60,000+ booksellers whose inventories we search appear to have any copies for sale.

It's a shame, this looks like an interesting book. Does it contain any contact information for the author? I could create a server-hosted version of the code that wouldn't be downloadable but would allow people to fill out a Web form and get the basics out, if the author was willing to allow this.

Regards,
Chad
