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 ...

In this lecture taped before a live audience of elementary and middle school students and their families, MIT Physics Professor Walter Lewin explains polarization, and demonstrates properties of light in rainbows, smoke and the sky. He answers the perennial question, "why is the sky blue?" and creat ...

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 ...

Have you ever wondered about the annoying hum your car makes at a certain speed on a particular stretch of highway? Or why a flute’s notes are higher than a trombone’s? Walter Lewin uses rubber hose, wooden boxes with holes, metal plates and an assortment of other home-made instruments to demonstrat ...

The inimitable Walter Lewin gives a literally hair-raising performance in this MIT Museum lecture/demonstration for learners young and old. He unveils the real meaning behind words and things most of us use everyday without reflecting on what marvels they really represent.
Here are some of the myst ...

**1. Shape of the Projectile Trajectory:**
Professor Lewin reviews the equations for projectile motion, showing that the trajectory is a parabola. He derives formulas for the highest point (maximum height), the time to reach the highest point, the time of flight (until impact), and the horizontal d ...

**1. 1D Work and Kinetic Energy:**
The equation for work, and its units are introduced. The work-energy theorem is derived showing that the change in kinetic energy equals the work done on a particle by the sum of all forces (thus the net force). Gravity does negative work on an object thrown upwar ...
