Fundamentals 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.

Fundamentals of Physics, II (PHYS 201) Waves on a string are reviewed and the general solution to the wave equation is described. Maxwell's equations in their final form are written down and then considered in free space, away from charges and currents. It is shown how to verify that a given set of fields obeys Maxwell's equations by considering them on infinitesimal cubes and loops. A simple form of the solutions is assumed and the parameters therein fitted using Maxwell's equations. The wave equation follows, along with the wave speed equal to that of light (3 x 10^8), suggesting (correctly) that light is an electromagnetic wave. The vector relationship between the electric field, the magnetic field and the direction of wave propagation is described. 00:00 - Chapter 1. Background 04:43 - Chapter 2.

Fundamentals of Physics, II (PHYS 201) The electric field is discussed in greater detail and field due an infinite line charge is computed. The concepts of charge density and electric flux are introduced and Gauss's Law, which relates the two, is derived.
