Paul Trow  
Trow's interactive web pages and perl software let you graph the LotkaVoltera equations and see interconnected predator and prey populations plotted over time; model the trajectory of a cannonball for different muzzle velocities and angles of elevation, and see the projectile's flight path plotted over time; draw graphs of ellipses with different parameters; convert angles between radians and degrees; perform arithmetic and find square roots modulo an integer; and create bar graphs of pro basketball statistics (points per game, rebounds per game, assists per game, steals per game, blocks per game, turnovers per game, field goal percentage, free throw percentage, and 3point percentage) by searching for player names or selecting NBA or ABA teams. See also Trow's articles "Dynamical Systems on the Torus," "Chaos and the Solar System," "The Normal Curve and Galton's Board," and "A Famous Infinite Series"; and research into symbolic dynamics.
