We know that some stars exist because we can see them with our own eyes. In this lecture Walter Lewin provides illuminating evidence of stars we cannot see. He describes the birth of stars, in the arms of a nebula, to their explosive or implosive ends. There are super hot white dwarves, detectible o ...

An alternate title for this talk might be “Walter’s World of Waves.” First, Lewin methodically explores how water and sound move in traveling waves. With a pan of water and a tuning fork, Lewin demonstrates concepts of oscillation, amplitude and velocity. He deploys equations for determining wavelen ...

**1. SHO of a Physical Pendulum:**
The SHO equation of motion (small angle approximation) for a rigid body pendulum is derived from the torque equation about the point of suspension. The periods of oscillation are worked out for four different shapes (rod, hoop, disk and for a billiard ball hanging ...

**1. Intro to Ideal-Gas Law and Avogadro's Number:**
Liquids are near incompressible, but gases are not; the density of gases can be increased with relative ease by increasing the pressure, but that is not the case for liquids. The ideal-gas law is introduced and explained; it is a good approximati ...

**1. Discrete Energy Levels:**
Electrons orbit their atomic nucleus in well defined orbits corresponding to discrete energy levels. The electrons can jump from one energy level to a vacant energy level, but they cannot exist in between. Transitions between these energy levels gives rise to absorpti ...
