Members inducted into the U.S. National Inventors Hall of Fame in 2010 included Yvonne Brill, whose electrothermal hydrazine thruster keeps satellites in space orbit, as well as Arthur Fry and Steven Silver, who created sticky notes (Fry, the concept; Silver, the glue). “Note: It took one woman to invent a rocket thruster,” wrote a Washington Post reporter about the induction ceremony, “and two men to invent Post-its.”

Muscle Shoals, Alabama, site of a huge munitions plant during World War II, had a surplus of ammonium nitrate in 1946. The U.S. Department of Agriculture suggested that the chemical, a primary ingredient in explosives, be used as fertilizer. Industrial production of the resulting synthetic fertilizer led to an explosion in corn yields in the 1950s. A Tennessee Valley Authority representative recounted that “as soon as the need for nitrate explosives fell off, we were ready to convert that to agricultural nitrate.” “We are eating the leftovers of the Second World War,” the environmental activist Vandana Shiva said in a 2005 speech.
One of the earliest known instances of wild carnivores being held in captivity in Mesoamerica dates to around the second century in Teotihuacán; excavations starting in the late 1990s uncovered the remains of almost two hundred animals—including wolves, eagles, and jaguars—in the Pyramids of the Sun and the Moon. The skeletons showed bone breaks, bone fusion, and abnormal growths, as well as indications of a human-controlled diet.
After the suicide of one of his former patients, Zimbabwe-based psychiatrist Dixon Chibanda began training local grandmothers in evidence-based talk therapy. Since 2006 over four hundred grandmothers have been trained to deliver free services in more than seventy communities across the country while sitting on a “friendship bench” next to a local clinic. Friendship-bench patients were found after six months to have improved more significantly than patients receiving standard care. “I value human beings so much,” said one grandmother in the program. “I introduce myself and I say, ‘What is your problem? Tell me everything, and let me help you with my words.’ ”
Southern women during the Civil War chewed on newspapers, believing an ingredient in the ink whitened their faces.
In 1864, responding to his friend Victor Hugo’s invitation to visit Guernsey, where the writer was living in exile, the French painter Gustave Courbet wrote, “In your sympathetic retreat I will contemplate the spectacle of your sea. The viewpoints of our mountains also offer us the limitless spectacle of immensity. The unfillable void has a calming effect. I confess, poet, I love terra firma and the orchestration of the countless herds that inhabit our mountains. The sea! The sea with its charms saddens me. In its joyful moods, it makes me think of a laughing tiger; in its sad moods, it recalls the crocodile’s tears and, in its roaring fury, the caged monster that cannot swallow me up.”
Accounts varied of the Great Famine of 1315–22, during which more than 10 percent of Europe’s population died. In Flanders: “Parents killed their children and children killed parents, and the bodies of executed criminals were eagerly snatched from the gallows.” In France: “There was no wine in the whole kingdom.”
According to the iron hypothesis, sprinkling iron into low-chlorophyll regions of the ocean would create large algal blooms. Oceanographer John Martin argued that large-scale iron enrichment could grow enough algae in the oceans to absorb carbon from the atmosphere and reverse the greenhouse effect. “Give me half a tanker of iron,” he famously said in 1988, “and I will give you an ice age.”
Joseph Conrad recalled, “It was in 1868, when nine years old or thereabouts, that while looking at a map of Africa of the time and putting my finger on the blank space then representing the unsolved mystery of that continent, I said to myself, with absolute assurance and an amazing audacity which are no longer in my character now, ‘When I grow up I shall go there.’”
“There is a story, repeated by a number of Roman writers,” explained the classicist Moses Finley, “that a man—characteristically unnamed—invented unbreakable glass and demonstrated it to Tiberius in anticipation of a great reward. The emperor asked the inventor whether anyone else shared his secret and was assured that there was no one else; whereupon his head was promptly removed, lest gold be reduced to the value of mud.”
In the summer of 1867, Chinese laborers working on the Central Pacific Railroad in the Sierra Nevada went on strike, demanding a pay increase and a ten-hour workday. Desperate to resume the railroad’s progress, executives considered asking the Freedmen’s Bureau to send African American laborers to take over. “A Negro labor force would keep the Chinese steady,” one executive wrote, “as the Chinese have kept the Irishmen quiet.”
Poet Edward Fairfax kept a 1621 account of his daughter Helen’s terrible nightmares, describing an incident in which she complained about a demonic white cat that “has been long upon me and drawn my breath.” The cat, she said, “has left in my mouth and throat so filthy a smell that it does poison me.”
At thirty-one ounces, the Trenta, a new drink size introduced by Starbucks in 2011, holds the same volume as the average capacity of the human stomach.
A 2018 study run at Buttercups Sanctuary in Kent, England, found that goats are sensitive to human emotions and strongly prefer to sniff smiling, happy faces rather than frowning ones.
According to a biographer, Honoré de Balzac called out on his deathbed for Dr. Horace Bianchon, a fictional creation that appeared in thirty-one of his stories. “Send for Bianchon,” the novelist said to his attending physician.
