Newton's Law of Universal Gravitation has a constant in it called, predictably, the Universal Gravitation Constant, or Big G. This is the story of the first experiment to measure G with reasonable accuracy. The story...of the Torsion Balance.

In this video, I explore how the Hall Effect works and why it's incredibly useful. Spoiler alert: the Hall Effect can be used to measure magnetic field. AND, the Hall Effect can be used to measure current! AND, the Hall Effect can embarrass a dead man...

In this stupid miniseries, I do the calculus for you so you can just sit around and pretend to learn.
Perhaps there's a better way? Watch this afterwards to check your work or get a hint if you're stuck? Try to replicate my result without peeking after...

My Breakthrough Junior Challenge topic this year was the Fourier Transform. I wanted to explain it because many people have heard of it, but they just don't understand how it works or what it actually does. Watch the video to learn about the Fourier Trans...

This is more of a sociologically interesting video. I filmed about fifty people who stayed right on the border of totality to watch the eclipse. Most were high-school students. Because of the slightly larger-than-average size of the Sun, we were not su...

I'll solve the classic slipping ladder statics problem, but where the angle of the ladder is not known. We do know the coefficients of friction and the masses of the ladder and the zombie, though, so that's awesome. And we know how far up the zombie has...

Here we discuss the technique of four-terminal sensing, which can be used to measure resistance very accurately. In particular, it can be useful for measuring the resistivity of a material.
Hint - don't use your multimeter (DMM) to directly measure the ...

Since I was little, I've puzzled to varying degrees over how the tops of clouds become positive and the bottoms become negative. The best explanation I'd extracted from anyone had been, "Maybe the bits that become negative are heavier since they have ext...

This is a discussion of why the quantum mechanical odds of finding an electron at the nucleus are vanishingly small. Wonderfully, this would not be the case in a universe with fewer spatial dimensions. Since we can simulate lower dimensions easily with ...

This student is in his first year of physics - get excited!
I wasn't there to ask mean questions, but if I had been, I would have asked him whether the two r's in his derivation were the same (they weren't). But he did a great job otherwise....

Indeed, he measured 1.67 hp for the stock configuration and 2.06 hp when all three modifications were in place. Don't worry - he didn't get full credit because he forgot to show any data. But ...
