The Department of Physics at MIT pushes back the frontiers of human understanding of space and time and of matter and energy in all its forms, from the subatomic to the cosmological and from the elementary to the complex.
A DC current is sent around a wire loop that is free to rotate. The current causes the loop to feel a torque in the presence of a magnetic field. Switching the current when the loop flips over allows it to continue accelerating, demonstrating the principle of a DC motor and the Lorentz force ...
Leyden Jars, an early style of capacitor, can be connected to the two electrodes of the Wimshurst Machine. They will store charge as it is generated, giving a much stronger spark across the gap. Next we have a three-piece dissectible Leyden Jar consisting of two metal cups separated by a ...
A double jointed pendulum hangs from a rod. Swinging the pendulum with high energy results in motion that cycles chaotically between normal modes. Swinging it with low energy results in more predictable motion. When viewed under black lights, it is easy to see that the first joint of the ...
Just how orderly is everything around us, from a set of three dice to all of the stars above us?

The researchers needed to be able to change a cat's lapping speed in order to test their theory. So they developed a robotic version of a cat's tongue -- a mechanical column with a 1-inch glass disk at the tip. This device allowed the researchers to study the liquid column for different ...
MIT alum and physicist Ronald E. McNair, who was the second African American to enter space, was first a kid with big dreams in Lake City, S.C.
In the electric field of a Van de Graaff generator, an unprotected Ben Franklin feels electrostatic forces. However, when a metal cage surrounds him, he is completely shielded against any electricity or electrostatic force. This is due to the fact that all charges in a conductor reside on the ...
The free fall of a coin and feather are compared, first in a tube full of air and then in a vacuum. With air resistance, the feathers fall more slowly. In a vacuum, the objects fall at the same rate independent of their respective masses.
