'A sequence related to a conjecture of Schinzel' A paper of mine related to the "p+1" problem. In the Journal of Integer Sequences.		Dictionary of Numbers A Java-based "dictionary of numbers" in which to look up characteristics of positive integers.
More on the p+1 problem Results of some calculations, and maybe a conjecture or two.		Gallery of Ulam Spirals Gallery of images made by coloring spirals of the positive integers, as suggested by Ulam's prime spiral.
Some statistics connected to the Grand Tours How well does a rider's prologue ranking predict his final GC ranking in a Tour? An on-going project.		Dice Problems A (slowly) growing collection of dice-related mathematical problems (currently 23) of varying difficulty, with solutions plus helpful appendices (in PDF).
A problem of probability in a game of darts A short paper illustrating the application of Markov chains to a problem arising in a dart game. In PDF, requires Adobe Acrobat Reader.		Animated Eigenvalues A small animation showing the relationship between eigenvalues of a matrix and an entry of that matrix.
Integer Sequence Noise MP3s of noise from integer sequences.		Paris-Roubaix plots Some plots of historical data related to the Paris-Roubaix bicyle classic.
A silly digits problem Some bits and pieces on a silly old digit problem. Worst proof ever And the end of a twenty year old question. Several pieces of my mathematics-related artwork are at SITO (external link). Mathematical graphics here.
