PHYS 224, Winter 2003
Thermal Physics


This page will contain links to resources, reference material, and java applets. I am organizing and adding to it as we go along.  Your suggestions for useful links are most welcome.

Here is the course web page from the last quarter, Autumn 2002.  The syllabus for that term was very different from ours, but there are some useful resources there.

Wolfram Reseach web resource - thermodynamics  New!

Hyperphysics - thermodynamics

Fluid mechanics
Special challenging questions for your diversion:
(1) (buoyancy) Quicksand (or mud) is much denser than the human body.  So why do people sink in it?!  Why do their eyes bulge before they disappear?  [Flying Circus of Physics, Q 4.130]
(2) (pressure) If you try to pour water into a coiled up hosepipe (wound around a horizontal axis and open at both ends) it often just won't go through, even if you're holding the end you're pouring into way up.  Why?  [Flying Circus, Q 4.8]
(3) Why do bugs explode over the windshield of a fast-moving car?  [Flying Circus, Q 4.28]

Aerodynamics of bicycles - a crash course in fluid dynamics.  Why do golf balls have dimples?
