Elements of a Feedback Loop
Paul Andersen defines the major elements of feedback loops. The receptors and effectors both sense and respond to changes in their environment. The following examples are used to illustrate the importance of feedback loops in...

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.

Nuclear Reactions
Mr. Andersen contrasts nuclear reactions to chemical reactions. He explains the four main forces of nature; including gravity, electromagnetism, strong, and weak nuclear forces. He also explains how fusion differs from fission.

TED-ED: How fast are you moving right now? - Tucker Hiatt
"How fast are you moving?" seems like an easy question, but it's actually quite complicated -- and perhaps best answered by another question: "Relative to what?" Even when you think you're standing still, the Earth is moving relative to...

What Do You Learn When You Touch the Sun?
Though our Sun is something we can count on to rise and set each day, it also comes with some phenomena that can catch us by surprise: solar winds. To better predict when these winds will travel all the way to Earth, we sent the Parker...
