Some of my Interests
Ancient Hindu Astronomy:
I have put together a few pages on my interests in Selected Topics in Hindu Astronomy and Related Ancient Astronomy.
Maya Calendar Converter:
Convert from Julian/Gregorian Calendar to the Maya Calendars (Long Count, Tzolkin, Haab and Lord of the Night) including pictures showing of how the Maya wrote the dates. Another Java applet.
Egyptian Pyramids:
My contribution to the subject is A Simple Model to Explain the Shapes of the Pyramids of Egypt.
Lunar Calculations:
Ancient astronomers were able to keep track of the phases of the moon with some very interesting algorithms. Here is a Javascript modern calculation of the date of the New Moon?
(O.K. The picture is of the Full Moon--not the New Moon! I know!)
Music from the 50s & 60s:
Gary Stevens, Professor of Mathematics, and I are the disk jockeys on "Blasts from the Past", the longest running "oldies but goodies" radio show in upstate New York. We are heard on Hartwick's own radio station WRHO. We've been spinning the oldies for nearly a quarter of a century!!
Genealogy:
Olde folks from long ago: Hartley ancestors.

 
Cool JAVA Physics (& other) Animations 

Animations of Some Interesting Physics etc.:
I have spent several months teaching myself JAVA so that I could create physics related animations on my WEB pages:

Some artificial insects with fully articulated legs, functioning eyes, and a sense of smell. And a course that I would like to teach.

A 3D graphic representation of the1/r gravitational potential with an object orbiting in an elliptical orbit.

The motion of the Moon and Sun to demonstrate when eclipses occur. You can use this to predict the next lunar or solar eclipse.

For my Astronomy and Light & Relativity students a hyperbolic surface viewable from various angles.

Fourier synthesis of a series of narrow pulses moving in a dispersive medium displaying wave packet spreading; whatever all that means.

For my Classical Mechanics course I present Chaos in a Pendulum. (See section 4.6 of Classical Dynamics of Particles and Systems, 4th ed. by J.B. Marion and S. T. Thornton, Saunders, New York, 1995, )

For my Classical Mechanics people you can Connect Masses by Springs and watch them oscillate. I stole the idea from Dennis C Rapaport

Some simple demonstrations of animal kinesiology: The action of a leg walking and a cat walking for a mini-course I taught on animal physics. Swing those hips and legs!!!

Keep track of the Sun with a vertical gnomon analemma sundial (and learn about gnomon, analemma and shadows produced by the Sun.)
A few courses I have taught recently, just for fun
