The Hungarian American physicist Leo Szilard first conceived of the nuclear chain reaction—a crucial milestone in the development of the atomic bomb—on a gray London morning in September 1933 while waiting for a traffic light to change from red to green. “It suddenly occurred to me that if we could find an element…which would emit two neutrons when it absorbed one neutron,” he wrote, this element could “liberate energy on an industrial scale, and construct atomic bombs.” In his book on the history of the bomb, historian Richard Rhodes writes that “as he crossed the street time cracked open before him and he saw a way to the future, death into the world.”

A longtime practice of European peasants was to bring cows and sheep inside for the night. If one could ignore “the nastiness of their excrements,” a late seventeenth-century visitor to Ireland opined, “the sweetness of their breath” and “the pleasing noise they made in ruminating or chewing the cud” might lull a person to sleep. A visitor to the Hebrides noted, however, that while urine was regularly collected and discarded, the dung was removed only once a year.
“Not one cent for scenery,” Republican House Speaker Joseph Gurney Cannon said in opposition to President Theodore Roosevelt’s conservation agenda. In 1965 President Lyndon Johnson, at the signing of a conservation bill, said, “Today we are repealing Cannon’s law.”
In 2014 the Federal Trade Commission charged the operator of Jerk.com with improperly obtaining personal information from Facebook to create 73 million profiles that identified people as “jerk” or “not a jerk” and then offered them the option to change their profiles for $30. According to the FTC, consumers who paid the fee often got nothing in return.
Yemen’s parliament passed a law setting the minimum age for marriage at seventeen in 2009, having been spurred by the national attention given to the story of ten-year-old Nujood Ali, who was granted a divorce from a thirty-year-old man. The child-marriage legislation passed in parliament but was put on hold by conservative members, citing potential inconsistencies with Sharia law.
Euripidean drama requires “the sudden jolt of the machine” to clarify the characters’ “peculiar sense of the political,” writes classicist John Snyder. “The deus ex machina breaks in because that is what history does…outside forces, irrational, nonhuman in origin and agency, yet utterly human at the same time, make people do what they do.”
One in four thousand people are said to suffer from photosensitive epilepsy, in which flashing computer screens can induce seizures. In 2008 the World Wide Web Consortium determined that online content should not flash more than three times in a one-second period. Federal government websites must design pages that avoid screen flickering within the range of 2 to 55 hertz.
During a battle with Scythians in Macedonia on April 29, 1091, Byzantine emperor Alexius I Comnenus noted the midday sun “shedding its rays,” reported his daughter Anna Comnena in the Alexiad. He dispatched local peasants to bring water in skins or jars to his troops, who “sipped a drop of water, then returned to the fray.” The newly hydrated Byzantines wiped out their enemies, and a chant began: “All because of one day the Scythians never saw May.”
In 1938 Guy Stewart Callendar published a paper titled “The Artificial Production of Carbon Dioxide and Its Influence on Temperature.” “It may be said that the combustion of fossil fuel…is likely to prove beneficial to mankind in several ways,” concluded Callendar. “The small increases of mean temperature would be important on the northern margin of cultivation, and the growth of favorably situated plants is directly proportional to the carbon dioxide pressure. In any case, the return of the deadly glaciers should be delayed indefinitely.”
In his catalogue of the world’s people in his Natural History, Pliny the Elder mentioned Scythians who feed on human flesh, Africans who “are frequently seen to all appearance and then vanish in an instant,” the Arimaspi who have only one eye, the Adrogyni who possess male and female parts, and the Monocoli who are born with “only one leg, but are able to leap with surprising agility.”
Forty-five years ago, cosmologist Brandon Carter postulated that no observer should expect to find that he or she had come into existence exceptionally early in the history of his or her species. “Suppose you know that your name is in a lottery urn,” writes philosopher John Leslie, “but not how many other names the urn contains. You estimate, however, that there’s a half chance it contains a thousand names, and a half chance of its containing only ten. Your name then appears among the first three drawn from the urn. Don’t you have rather strong grounds for revising your estimate? Shouldn’t you now think it very improbable that there are another 997 names waiting to be drawn?”
British historian Orlando Figes admitted in 2010 to posting scathing reviews on Amazon for books by other Russian-history specialists. Using the name Historian, he called one work “dense and pretentious” and complained another was not “worth the bother of ploughing through its dreadful prose.” Of Figes’ own The Whisperers, Historian posted that it “leaves the reader awed, humbled, yet uplifted” and wrote of its author, “I hope he writes forever.”
Archaeologists in France discovered in 1865 a Stone Age human skull with a hole sawed in it. They believed it had served as a drinking vessel; one wrote the hole was “expressly made for the application of the lips.” But later study by an anatomist proved this to be incorrect: the skull was actually evidence of ancient brain surgery.
Thomas Jefferson never wrote or said, “I’m a great believer in luck. The harder I work the more I seem to have.” The quip was crafted by San Francisco humorist Coleman Cox for a 1922 collection titled Listen to This.
Plutarch related that news of the Athenians’ brutal defeat at Syracuse during the Peloponnesian Wars first came from a stranger who told the story at a barbershop “as if the Athenians already knew all about it.” When the barber spread the news, city leaders branded him a liar and an agitator. He was “fastened to the wheel and racked a long time.” Official messengers later came with the “actual facts of the whole disaster,” and the barber was released.
