TED-Ed: What is the Heisenberg Uncertainty Principle? - Chad Orzel
The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time....

Quantum Tunneling Takes a Surprisingly Long Time
Quantum tunneling happens when a particle seemingly teleports across a barrier. But despite how instantaneous this event sounds, recent research suggests that it doesn’t happen nearly as fast as you might think.

Dennis Hong: Making a car for blind drivers
Using robotics, laser rangefinders, GPS and smart feedback tools, Dennis Hong is building a car for drivers who are blind. It's not a "self-driving" car, he's careful to note, but a car in which a non-sighted driver can determine speed,...

Position vs. Time Graph - Part 1
Mr. Andersen shows you how to interpret a position vs. time graph for an object with constant velocity. The slope of the line is used to find the velocity. A phet simulation is also included.
