II. Interactive Web Application
Version #1: Research, how far you can fly on direct flights out of a given city (i.e. without changing planes).
Version #2: Research, how far you can fly out of a given city (possibly changing planes) while stopping at up to a certain number of intermediate cities.
|
This interactive Web application is a visualization of the international
passenger air traffic network. You can select one or more cities from a list of
approx. 3800 cities in the world, and the application will then show you
all flights originating from those cities on a zoomable world map. [More...]

Constructing Regular Polygons — Primitive Roots of Unity (created 1/08, somewhat ongoing)
|
||||||||||||||||||||||
Load my Primitive Roots of Unity page | I have been working for quite a while on finding closed, simple expressions for primitive roots of unity, that is finding solutions of cyclotomic polynomials by radical expressions in the case of constructible regular polygons. The goal is to find solutions for the 5th, 17th, 257th, and 65537th root of unity. This is an ongoing project. | |||||||||||||||||||||
