Henry T. Brown’s 1868 mechanical encyclopedia Five Hundred and Seven Mechanical Movements is being animated on this fascinating site — see working demonstrations of hundreds of mechanical linkages from the age of steam.
Note that it’s a work in progress — the movements that have been animated are indicated with colored thumbnails. Owner Matt Keveney plans eventually to animate all 507 movements in Brown’s original text.

In 1830 Joseph Palmer created an odd controversy in Fitchburg, Massachusetts: He wore a beard when beards were out of fashion. For this social sin he was shunned, attacked, and ultimately jailed. In this week’s episode of the Futility Closet podcast we’ll tell the story of a bizarre battle against irrational prejudice.
We’ll also see whether a computer can understand knitting and puzzle over an unrewarded long jump.

Margaret Isabel Dicksee’s 1893 painting The Child Handel is based on a story about the composer’s childhood:
Handel’s father strongly opposed the child’s passionate love for music, and the more his great gifts developed the more severely was he forbidden to occupy himself with music. The little boy was obliged to have recourse to subterfuge, and when his elders believed him snug in bed he used to steal on tip-toe to the lumber-room, where he had discovered an old spinet, on which he played softly to his heart’s content, alone and fancy-free. In one of these moments of enjoyment, when the divine genius spoke to the child, he forgot himself and played louder and louder — all the sound of the old spinet streamed through the silent night, waking the sleepers in the house, who believed that the angels were keeping vigil over the old town of Halle. But little George’s father bethought himself of the musical propensities of the boy, and, as the latter was not to be found in his bed, the lantern was lit and a search-party followed where the music led them. Alas! Poor George was found, severely reprimanded, and dismissed to bed.
This telling is from the Strand, April 1904. The story is disputed, but Handel did display enough skill as a child to induce Duke Johann Adolf I to recommend him for musical instruction.

Tokyo has the world’s busiest train stations, handling 13 billion passenger trips a year. To keep things running smoothly it relies on some subtle features to manipulate passenger behavior.
Blue lights mounted discreetly at either end of a platform, the points at which prospective suicides contemplate leaping into the path of oncoming trains, have been associated with an 84 percent decline in such attempts.
Rail operator JR East commissioned composer Hiroaki Ide to replace the grating buzzer that used to signal a train’s departure with short, pleasant jingles known as hassha melodies. These have produced a 25 percent reduction in passenger injuries due to rushing.
Stations also disperse young people by playing 17-kilohertz tones that can generally only be heard by those under 25. And rail employees are trained to use the “point and call” method, shisa kanko, in executing tasks. Physically pointing at an object and verbalizing one’s intentions has been shown to reduce human error by as much as 85 percent.

Lewis Carroll’s 1885 puzzle book A Tangled Tale bears an anonymous dedication:
Beloved Pupil! Tamed by thee, Addish-, Subtrac-, Multiplica-tion, Division, Fractions, Rule of Three, Attest thy deft manipulation! Then onward! Let the voice of Fame From Age to Age repeat thy story, Till thou has won thyself a name Exceeding even Euclid's glory!
He was thinking of Edith Rix, a child-friend who went on to study mathematics at Cambridge. She might have divined without asking that the dedication was intended for her. How?

In 1976 psychologist Harry McGurk discovered that seeing a person speak affects our impression of the sound we hear. Faced with conflicting information, the brain seems to make its “best guess” as to what it’s perceiving. In some cases a third sound is produced: When the syllables /ba-ba/ are spoken over the lip movements /ga-ga/, the perception is /da-da/.
This casts doubt on the assumption that the senses operate separately and can be studied in isolation. Psychologists and philosophers are still considering the implications.

Felix Alston, the baseball-obsessed warden of the Wyoming State Penitentiary, wanted his prison’s team to be the best possible. So in 1911 he told his players that so long as they kept winning they would receive stays of execution.
The All Stars were murderers and rapists sentenced to death; they entered and left the field chained together in irons. But in 1911 death sentences were usually carried out within a few months, and the warden’s offer apparently had a strong effect: Between March 1911 and May 1912, the team won 39 of their 45 games.
It couldn’t last. The state supreme court justice who helped arrange the stays (and profited by his bets) came under increasing pressure to carry out the sentences, and when star shortstop Joseph Seng was hanged on May 24, 1912, the team’s winning streak came to an end. In the months that followed, one player escaped, five were hanged, and five were gassed to death. By 1916 the team was a memory.
We ought to apologize for what our ancestors did to other people. This requires that we sincerely regret those deeds. But that means that we would prefer that the deeds had not been done, and if this were the case then world history would be significantly different and we ourselves would probably not exist. Yet most of us are glad to be alive. Can we sincerely regret deeds that are necessary to our own existence?
(That’s from La Trobe University philosopher Janna Thompson. She says the best solution is to interpret the apology as regret for this state of affairs. “[T]he regret expressed is that we owe our existence and other things we enjoy to the injustices of our ancestors. Our preference is for a possible world in which our existence did not depend on these deeds.”)
