Investigating the Astronomical Clock of Prague
For use on Mathematica 4.0 promotional materials, Wolfram Research
created a sample notebook briefly sketching the geometry behind the Orloj,
an astronomical clock, which since the year 1410, has tracked the motion of the
sun and moon in the sky over Prague. This article will describe the clock in
more detail, including a description of the mathematical model behind it.
