In 1986 a Greek professor encountered a previously unknown word while deciphering a fifth-century lexicon olisbokollix, meaning “loaf-of-bread dildo.” Later discovery of vase paintings showing women carrying baskets of phallus-shaped loaves confirmed the word had been understood correctly.

The earliest reliable account of human flight concerns a Benedictine monk named Eilmer, who in 1066 fastened wings to his hands and feet, jumped from a tower, and glided more than six hundred feet before falling from the sky and breaking both his legs. He blamed the failure on not having fitted himself with a tail.

Before Sally Ride spent a week aboard the Challenger shuttle in 1983 and became the first American woman in space, NASA engineers asked her if she wanted a hundred tampons in her flight kit. “No,” she later recalled responding, “that would not be the right number.” They said they wanted to be safe. “Well,” she assured them, “you can cut that in half with no problem at all.”

In the 1860s editor William Bullock invented a printing press that used continuous-roll paper; it made double-sided copies in mass quantities and transformed publishing. Two years later Bullock got his leg stuck in the press’ belt mechanism while installing one at a Philadelphia newspaper, developed gangrene, underwent an amputation, and died during the operation.

“Utter damned rot!” is what William Berryman Scott, a former president of the American Philosophical Society, said in response to Alfred Wegener’s theory of continental drift, first proposed in 1912. “Wegener is not seeking the truth,” said a doubtful geologist, “he is advocating a cause and is blind to every argument and fact that tells against it.”

In the Arabian Nights, Shahrazad tells of a merman who guides a fisherman around the ocean floor, where underwater societies shun clothing, commerce, and religious restrictions. “I have seen enough,” the fisherman says after eighty days, “for I am getting tired of eating fish.”

Color film in the 1950s barely registered dark skin tones; Kodak had developed the product to measure images against the white skin of a model known as Shirley. The company eventually modified its film emulsion, responding to complaints from advertisers promoting wood furniture and chocolate.

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.”

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.

Thirteenth-century professor Thaddeus of Bologna once claimed anyone who ate eggplant for nine days would go insane. A student decided to test the theory and after nine days returned to report he was not mad. Thaddeus asked him to turn around; on observing the student’s behind he announced, “All this about the eggplant has been proved.” It is said the student subsequently wrote a learned treatise on the subject.

Students at the Federal Polytechnic Institute in Zurich wrote to Carl Jung in 1949 to ask what effect he thought technology had on the human psyche. “The danger lies not in technology,” Jung responded, “but in the possibilities awaiting discovery.” The question regarding new discoveries was “whether man is sufficiently equipped with reason to be able to resist the temptation to use them for destructive purposes.” This, Jung concluded, “experience alone can answer.”

In his autobiographical novel Boyhood, Leo Tolstoy describes his youthful joy in philosophical abstraction: “I frequently imagined myself a great man, who was discovering new truths for the good of mankind, and I looked on all other mortals with a proud consciousness of my dignity.” His euphoria didn’t last. “Strange to say,” he wrote, “whenever I came in contact with these mortals, I grew timid.” Soon he was “ashamed of every simplest word and motion.”

Hero of Alexandria invented the aeolipile, a primitive steam engine, in the first century. A hollow sphere with elbow-shaped tubes mounted on an axle and suspended over a cauldron of boiling water, the engine likely could not have powered anything. “It should probably be remembered,” wrote historian William Rosen, “as the first in a line of engineering dead ends.”

Statistician Stephen Stigler wrote in 1980, “No scientific discovery is named after its original discoverer.” He identified this as a basic law of eponymy, admitted he was an “outsider to the sociology of science” acting in “flagrant violation of the institutional norms of humility,” and named the law after himself.

A 52-million-year-old fossilized tomatillo found in January 2017 revealed the fruit to be five times older than scientists had previously thought. “The initial discovery was a very big OMG moment,” said paleobotanist Peter Wilf. “I was like, ‘Wait a minute, wait a minute, wait a minute. Could it be? Could it be? Could it be? Really? Really? Really?’ Then I just went nuts.”
