According to Yoshida’s calculations, the proportion of Japanese named Sato increased 1.0083 times from 2022 to 2023. Assuming the rate remains constant and there is no change to the law on surnames, around half of the Japanese population will have that name in 2446, rising to 100% in 2531.

the fact that the universe has expanded from, say, a Planckian size to 10⁻⁵m in a very short time, invites the suggestion that this expansion was caused by a collision with a larger universe, i.e. that it was really our Universe which was absorbed in another "parent" universe.

While a continuous absorption of microscopic baby universes probably can be accommodated in a non-disruptive way in our Universe, it is less clear what happens if the "baby" universe is not small, since we have not suggested an actual mechanism for such absorption.

to protect themselves against swarms of sexually aroused male frogs, the female frogs stiffly extend their arms and legs away from the body, keeping incredibly still until the male releases them from its grasp.

The Yerkes Laboratories eventually developed a device known as a Chimpomat. This Chimpomat would receive either metal or plastic disks and would dispense some form of food reward in return for the insertion of a disk. Animals were eventually taught to pull the box of weights up to the cage in return for plastic or metal disks which they could then take and put in the Chimpomat to get their reward.

By the process of lengthening the time between which they could earn the reward and when they could actually receive it by using the Chimpomat (by making the Chimpomat available only certain times of the day), the animals could be trained to collect plastic disks, in other words, to work for money. They would store up this money until the time came for them to spend it. Eventually they were trained to earn the money one day and spend it in the Chimpomat the following day.

On these occasions the animals used to walk around clutching their earnings to their breasts, sleeping on them at night so they would not be stolen, and getting very hysterical if any other animal came near their earnings or tried to take any of them away—a very human side of their actuvity and the dawn of ownership of private property and capitalism, a thought that has intriguing implications.
