We Love You, Edward

Edward passed away in Alaska while crossing the Jago River after an attempt on Mt. Isto, the most prominent point in the Brooks Range. This website is a copy of Edward's website. ( don't go there, it doesn't work anymore )

We will continue to use this website to release items such as scans of Edward's last mathematical works, photos of his polyhedra, or links to his WinProm software releases.

Last Math Works

On entering Edward's condo in Redmond after his death, there were several stacks of papers filled with mathematical calculations ... probably the items he was working on and thinking about at the time in the months or years before his death. It may have to do with trying to optimize winprom, or almost anything else. There are few notes and little documentation. Each sheet is a separate scanned pdf. I tried to preserve the order and grouping of the sheets as much as possible, and collect each group into a pdf.

I would encourage anyone interested in the mathematics and programming of worldwide mountain geographies to download and investigate these works. I have an undergraduate degree in Mathematics, and I can only understand 20% of it.

Earl's Laws of Mathematical Ethics:

Any unit of angle other than the radian is mathematically ugly.
Any continuous logarithm or exponential to any base other than e is mathematically ugly.
The absolute value function is mathematically ugly.

I am often known to call myself "7.389056099", which is (to the number of significant digits shown) a transcendental number that can be obtained in only two or three keystrokes on a typical scientific calculator. Can you figure out what this number means? Hint: see Earl's Second Law of Mathematical Ethics.
