To understand torque-induced precession, we must start by looking at the relationship between angular momentum and torque. Angular momentum is a vector quantity dependent on an object’s moment of inertia and angular velocity. Torque is also a vector quantity that represents the amount of force necessary to rotate an object along a given axis. These two quantities are directionally perpendicular to one another. The torque causes a change in direction of the angular momentum, but the magnitude remains unchanged. Thus, the bicycle wheel is able to spin gyroscopically, or precess, along its horizontal rotational axis in opposition to its vertical rotational axis.

“There was one time when we were children, he transformed himself into a snake, and he knows that I love snakes. So, I went to pick up the snake to admire it and he transformed back into himself and he was like, ‘Blaah, it's me!’ And he stabbed me. We were eight at the time…” – Thor recalling growing up with Loki in Thor: Ragnarok 🐍
The "Uncanny Valley" is an effect in which a computer generated character looks too human to accept as a cartoon, but too cartoony to accept as a real human.
The effect is named after the Uncanny Valley near Silicon Valley in California. In the early days of computer animation, Silicon Valley programmers would wander the Uncanny Valley between work shifts, discussing their projects and looking for inspiration in nature.
It was on such a walk that the programmers encountered Wally Urundak. Wally was a hermit who lived in the valley and he often invited programmers in for tea or lemonade, depending on the temperature outside. Wally was a friend to many, though many also recognized something was awry. Wally seemed normal, perhaps even too normal. He was always happy, he was always polite, he always spoke clearly and enunciated well, and his expressions were always crystal clear.
One day, a programmer named Vig Ruskin noticed what appeared to be a wire running out of Wally's left pant leg. He didn't want to be rude so he didn't ask about it, but he mentioned it to other programmers and word slowly traveled about the suspicion that the seemingly perfect Wally was a robot. It would make sense, they were in the computer capital of the world and many suspected that this strange fellow was an experiment, perhaps of Bill Gates or another famed computer wizard. So on a cold Tuesday afternoon as Vig and his friends ventured to the Uncanny Valley to visit Wally, they brought a pair of wire cutters.
They met Wally and sat down and had a chat, speaking in ad hoc Turing tests to see if they could trick Wally into admitting he was run by a computer mind. He passed them all. Then, Vig had his friend Martin trick Wally into looking out the window while Vig himself jumped down and cut the wire. Wally fell over immediately. They thought it was proven.
But then- The wire started bleeding.
Wally began to smell bad, rotten almost immediately. He deflated and decomposed as they watched. And a horrible groaning sound emerged from deep within the house's basement.
It turned out that Wally was like the bait at the end of an anglerfish's lure, and was only part of the house itself, which was a massive underground life-form that had been eating the brains of several missing Silicon Valley programmers. The police and animal control were called and eventually for the safety of the neighborhood they had to kill the creature with poison. It decomposed quickly and deflated leaving little but an organic slime that contained no viable DNA to study.
The Uncanny Valley effect is named for this strange beast and the human lure it presented, almost human but not quite. You can see the Uncanny Valley in such films as Tron: Legacy, The Adventures of Tintin, and anything starring Timothée Chalamet, who is suspected of being such a biological lure himself.
Aja: “Humans think that they are the center of the universe.”
Krel: “They’re several million light years away from that, actually.”
Confirmation in 3Below S1E3, Mind Over Matter, that Earth is not the geographic center of the universe in Tales of Arcadia (unless Akiridion astronomers are wrong, I guess), and therefore the magical center of the universe described in the movie is different; like how ‘magnetic north’ doesn’t perfectly match up with ‘true north’.
Steller's Sea Cow, a member of the group Sirenia, was the first historical marine mammal to go extinct at the hands of humans. Just 27 years after it was properly described in 1741, it had been wiped out. This was because they were killed for their meat on fur trade expeditions, and could feed many people. Adults could reach up to 10 metres in length while weighing up to 11 tons, bigger than many modern whales can reach.
The first Westerner to document tofu was a Spanish missionary in China in the 1660s that described it as “insipid cheese” and thought it was super crazy that the rich and the poor would both eat it
In the 1770s Ben Franklin read Father Naverrete’s book and wanted to try it out himself, so while he was in London he managed to get some “Chinese caravances” (an old word for garbonzo beans) and sent them to Philadelphia along with the Japanese ambassador’s account of how to make it, although since we don’t have an account of how it went I’m guessing it wasn’t a success
Anyway, alternate history: Franklin successfully recreates tofu and introduces it as a cheap base food during the Revolution, altering American food history
