For more information about Professor Shankar's book based on the lectures from this course, Fundamentals of Physics: Mechanics, Relativity, and Thermodynamics, visit http://bit.ly/1jFIqNu.Uploaded 22-09-08Fundamentals of Physics (PHYS 200)This is the first of a series of lectures on thermodynamics. The discussion begins with understanding "temperature." Zeroth's law is introduced and explained. Concepts such as "absolute zero" and "triple point of water" are defined. Measuring temperature through a number of instruments is addressed as well as the different scales of measurement. The second half of the lecture is devoted to heat and heat transfer. Concepts such as "convection" and "conduction" are explained thoroughly.00:00 - Chapter 1. Temperature as a Macroscopic Thermodynamic Property06:45 - Chapter 2.

Frontiers/Controversies in Astrophysics (ASTR 160)Uploaded 29-09-08The lecture begins with the development of post-Newtonian approximations from Newtonian terms. Several problems are worked out in calculating mass, force and energy. A discussion follows about how concepts like mass and velocity are approached differently in Newtonian physics and Relativity. Attention then turns to the discovery that space and time change near the speed of light, and how this realization affected Einstein's theories. Finally, the possibility of traveling faster than the speed of light is addressed, including how physicists might predict from laboratory conditions how this might occur. Muons, unstable particles that form at the top of the Earth's atmosphere, are used as an example.00:00 - Chapter 1. Velocity and Mass in Special Relativity08:34 - Chapter 2.

France Since 1871 (HIST 276)Uploaded 21-11-08The sacred union that united France's political parties during World War I contributed to a resilient morale on the home front. Germany's invasion of France, and the conflict over Alsace-Lorraine in particular, contributed to French concern over atrocities and the national investment in the war effort. New weapons and other fighting technologies, coupled with the widespread use of trenches, made fighting tremendously difficult and gruesome on all fronts.00:00 - Chapter 1.
