The Physics of Caramel: How To Make a Caramelized Sugar Cube

Watch the original video in Spanish here: https://www.youtube.com/watch?v=J2Vkv5GQXww This video is about how the physics and chemistry of sugar (in particular, how it melts, and how it caramelizes) is more complicated than you might think. It involves fructose, sucrose, glucose, and a sticky mess.

Feynman's Lost Lecture (ft. 3Blue1Brown)

Check out Grant’s channel: 3blue1brown: https://www.youtube.com/3blue1brown This video recounts a lecture by Richard Feynman giving an elementary demonstration of why planets orbit in ellipses. See the excellent book by Judith and David Goodstein, "Feynman's lost lecture”, for the full story behind this lecture, and a deeper dive into its content.

Spacetime Intervals: Not EVERYTHING is Relative | Special Relativity Ch. 7

Go to http://brilliant.org/MinutePhysics for 20% off a premium subscription to Brilliant! Mark Rober's youtube channel: https://www.youtube.com/markrober This video is chapter 7 in my series on special relativity, and it covers the idea that some things AREN'T relative: there IS a sense of absolute length and absolute time, which can be agreed upon from all moving perspectives (as long as they're inertial reference frames). In particular, pr...

Extraterrestrial Cycloids - Why Are They on Europa?

Thanks to the James Webb Space Telescope (JWST) and Space Telescope Science Institute for supporting this video. This video is about the cycloid curves on Jupiter's moon Europa - they're ridges or valleys in the icy surface that formed due to some sort of geological or tectonic-esque phenomenon. The answer involves ping pong balls, the pacific ring of fire, subduction, tidal bulges, and tailcracking, REFERENCES Europa image: https://upload....
