I'm Leo Izen, a student interested in mathematics, science, and computers. Check out my stuff on this page.
- Digital Clock - I built a working digital 24-hour clock using 7490A counter ICs, 7447 BCD to 7-segment ICs, and common anode 7-segment displays.
- Quads Rating Estimator - This estimates post-event US Chess Federation ratings for a 4-player round-robin event (often known as Quads). It requires all players' scores, rather than just your own, but it's dead accurate as long as certain assumptions hold.
- Rating Estimator - This estimates post-event US Chess Federation ratings for any regular USCF tournament. It only requires your rating, opponents' ratings and your score, and is not perfectly accurate. It's different from the USCF Estimator because it calculates expectancies and expected norms.
I've written a few standalone programs in Flash and Java.
- Tanks - This is a preliminary version that utilizes Perlin Noise to generate a landscape, then employs a Runge-Kutta method to trace projectiles with various forces acting on them.
- Electromagnetic Field Hockey - This is a preliminary version named after Electric Field Hockey on The University of Colorado's PhET website, but allows multiple moving charges and includes a constant into-the-screen magnetic field. It uses a Runge-Kutta method to track the moving objects.
- Conway's Game of Life - This simulates Conway's Game of Life. If you're not thoroughly bored with the game of life (unlike John Conway) or don't know what this is, see this Wikipedia article.
- Tic Tac Toe - Play Tic Tac Toe against a human or a computer at varying difficulties on either a traditional board, a flat torus or a klein bottle. After playing around with this for a bit, try to lose on difficulty level 0. It's harder than you think!
I write mods for the popular game Minecraft, under the pseudonym thebombzen.
The mods comprise AutoSwitch, EnchantView, MobAura, and WorldAndGenerationTweaks.
