About 40 percent of employers peer at the social-media profiles of prospective candidates, and 40 percent of party guests admit to snooping through a host’s medicine cabinet or drawers. The percent of women who admit to having looked through a partner’s phone without permission is 34 percent; of men, 62.

Fairy wren nestlings learn “passwords,” or unique single notes, from their mothers while still in their eggs; after birth they must use the passwords when calling for food, or the mothers will abandon the nest. In a 2012 study, scientists in Australia experimented with switching eggs and mothers, and found that passwords were not genetically inherited; the chicks assumed the passwords of their adopted mothers.
A 2013 study involving American college students found that participants were more likely to deem a face more attractive if it was presented amid a group of faces than if it was displayed alone. This “cheerleader effect,” scientists ventured, was “due to the averaging out of unattractive idiosyncrasies.” Two years later a similar study conducted with Japanese participants failed to replicate the results of the initial study.
Before the entire palette of modern mathematical notation existed, Johannes Kepler relied on musical notation to describe the planets’ rotation around the sun in his Harmonies of the World, published in 1619. The plus and minus signs were introduced in print in 1489 by Johann Widman, and the equal sign in 1557 by Robert Recorde, but the multiplication sign (×) was not introduced until 1631, by William Oughtred; modern exponential notation in 1637, by René Descartes; and the obelus (÷) to indicate division in 1659, by Johann Rahn.
Though described by Suetonius as having a “fat neck” and “potbelly,” Nero competed at the Olympics in 67, in the chariot race. He fell out of his vehicle and failed to finish but paid hefty bribes to the judges and secured first place.
In 1890 Russian botanist Dmitri Ivanovsky was commissioned to study a disease destroying tobacco plants in Crimea. Filtering the sap from affected plants, Ivanovsky discovered in 1892 the presence of a small parasitic microorganism invisible under great magnification—a virus—which he thought was a minuscule bacterium. In 1898 Dutch microbiologist Martinus W. Beijerinck became the first person to recognize viruses as reproducing entities distinct from other organisms.
At a Johns Hopkins campus hospital in 1920, behavioral psychologists conducted an experiment with a nine-month-old boy known as Little Albert, who was given a white rat to play with. The scientists then made loud noises behind Albert’s head while he played, conditioning in him a fear of other furry animals and objects, previously sources of joy. Albert’s mother, a wet nurse at a nearby hospital, was paid one dollar for her son’s participation.
Charles Mackenzie, a fur trader in Missouri in 1805, noted that the local American Indians with whom he traded held a low opinion of Meriwether Lewis and William Clark’s party when it came through. “The Indians admired the air gun, as it could discharge forty shots out of one load,” Mackenzie reflected, “but they dreaded the magic of the owners. ‘Had I these white warriors in the upper plains,’ said the Gros Ventres chief, ‘my young men on horseback would soon do for them as they would do for so many wolves, for, there are only two sensible men among them, the worker of iron and the mender of guns.’” The “sensible men” in question included neither Lewis nor Clark.
During the rule of Charlemagne in the late eighth and early ninth centuries, the Carolingian Renaissance saw the revival of Latin studies, the creation of a royal scriptorium, Alcuin’s revision of the Vulgate Bible, and the advent of a minuscule (lowercase) writing system, which eased the labor of copying. Charlemagne himself, however, could barely write a word in any language.
According to philosopher Alfred North Whitehead, “Writing was an invention which took about two thousand years to make its effect felt. Do you recall, even in Plato’s dialogues, the discussions are seldom if ever about what the participants have ‘read’ but almost invariably about what they ‘remember’?”
Wikipedia editing guidelines ask that page authors avoid including mission statements in entries. “These usually focus on platitudes rather than specifics,” the site warns. “In short, they rarely tell us anything useful.”
Malingering amnesia, in which a person fakes symptoms of memory loss, is often associated with attempted financial gain, typically among personal-injury claimants. According to a 2003 study, 29 percent of criminals sentenced to life imprisonment claimed at their trials that they suffered from amnesia. A visual recognition test, such as the Test of Memory Malingering, can be used to detect fraud of this kind.
Looking at the records of 35,000 Union Army veterans who had served between 1861 and 1865, a 2010 study found that soldiers whose military units lacked a sense of camaraderie were six times more likely to have had heart attacks or strokes by their late fifties or early sixties than counterparts from units with strong esprit de corps. “Somehow being armed with close social bonds in the extremely stressful situation of battlefield combat,” said one of the researchers, “has a protective effect that continues long after the fighting has ended.”
In July 1990, one year before the collapse of the USSR, scholar Nicholas Eberstadt testified before a Senate committee about a CIA study of the Soviet economy, which showed high Soviet meat production and per-capita milk output—exceeding U.S. levels—though shortages were widely reported by tourists and Soviet citizens. “The Soviet government routinely hides many of its efforts from outside views,” Eberstadt granted. “But where, one wonders, are the hidden stockpiles and reserves of Soviet meat?”
“I went sailing up to Great Point, which is fourteen miles. It was fine and rough so we went out in the open ocean and shipped water grandly. I have bought a large swordfish sword for the agassiz of an old salt by the name of Judas,” Ernest Hemingway wrote to his brother Marcelline in one of his earliest known letters, shortly after his eleventh birthday, in 1910.
