Description

Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetime Today I’m going to explain why you’re not falling through your chair right now using one simple fact, and one object. The fact is that all electrons are the same as each other, and the object is a structurally critical item of my clothing. There’s a chance this episode could get very weird.

Does any of this explain why USB plugs need to be turned 540° to return to the correct orientation?

This makes me feel like I've accidentally sat in on the wrong lecture, but I'm now too interested to leave. Thanks for the mental stimulation.

Matt: "don't worry, it's just addition and subtraction" Also Matt: *literally derives Slater determinants on-screen*

"Of course before you want to watch this you should familiarize yourself with the subjects we touched upon in the previous 30 episodes of Space Time..." Love this channel.

I've been confused for years about what "half integer spin" meant, and here Matt clarifies it in a few words.

Most textbooks or online lectures gloss over the deep meaning of the spin leaving one unsatisfied with the description. This is the first time i have seen someone explain the concept in a way makes it more satisfying an explanation. Kudos to Dr Matt O'Dowd for possessing such an ability!

Great explanation! Richard Feynman said that if he really understood some aspect of physics, he could explain it to a freshman. But the Spin Statistics Theorem stumped him. He was unable to come up with a simple explanation, which you have done. Bravo!

Bold of you to assume I'm not falling through my chair right now.
