Planck's constant is a thing we all hear about in high school physics classes, but no one really talks about why it's cool.

Textbooks will talk dryly about "blah blah theories of quantum gravity" and teachers will repeat that "something something a photon's energy to its frequency. And sure, these things are true. But when people say stuff like that, they're really burying the lede.

Planck's constant is about the limits of what's physically possible in the Universe!

Bonus: an article about Fans and AC from lowtech magazine lowtechmagazine.com/2014/09/ci

TL;DR AC sucks and are an ecological disaster while fan works well.

Isolation and trees around the building to produce massive shadows are also an effective way to prevent heat, but often overlooked because installing an AC is a lot easier.

Libro.fm is an amazing alternative to Amazon's Audible: an independent audiobook platform that sells books from every major publisher at the same price as Audible - but without DRM, and with a share of every sale going to an indie bookseller of your choosing.

Virtually every audiobook title is available through Libro.fm - except for those titles that Audible demands be sold as "Audible exclusives."

Semi-regular reminder that the word musk in English comes from the Latin word muscus. This, in turn comes from the Persian word mušk, which originated as the Sanskrit word muṣka, meaning scrotum.

So it's etymologically accurate to say Elon Ballbag.

The Cheddar Man was a Neolithic human found in England. He lived around 9100 years ago. Researchers analysed his DNA, which was fairly typical of Western Europeans at the time, and found that he was lactose intolerant, had green eyes, dark curly hair, and he was Black.

This made a lot of racists very upset, and I still find that pretty funny.

Bronze disease is caused by a combination of water, atmospheric oxygen, and chloride. These three things make an environment which will ultimately wreck any copper objects.

It works in a cyclic process:
• Oxygen oxidises the copper
• Copper forms copper (I) chloride CuCl
• That CuCl reacts with water, making a mixture of copper (II) chloride CuCl2, copper hydroxide Cu(OH)2, and hydrochloric acid

In air, the copper continues to oxidise, and form more hydrochloric acid, and so the process continues.
