On July 23, 1995, in New Mexico, the astronomer Alan Hale saw an unidentified fuzzy object in the sky. He emailed the Central Bureau for Astronomical Telegrams. In Arizona, Tom Bopp saw the same thing. He telegrammed the bureau. The comet was named Hale-Bopp the following day. Believing that a UFO was traveling behind it, thirty-eight members of The Heaven’s Gate cult committed suicide on March 26, 1997, six days before the comet reached its perihelion.

Mark Twain was born on November 30, 1835—two weeks after the perihelion of Halley’s Comet. “I came in with Halley’s Comet,” Mark Twain commented in 1909. “It is coming again next year. The Almighty has said, no doubt, ‘Now there are these two unaccountable freaks; they came in together, they must go out together.’” He died on April 21, 1910—one day after the comet had once again reached its perihelion.

Questions asked in TV commercials aired in 1993: “Have you ever borrowed a book thousands of miles away? Or sent someone a fax from the beach? Have you ever paid a toll without slowing down? Have you ever watched a movie you wanted to, the minute you wanted to?” The answer: “You will. And the company that will bring it to you? AT&T.”

By the end of the century, a report by the National Science Foundation in 1982 predicted, 40 percent of American homes will have “two videotex service”—a term describing the emergent conjunction of communications and computing. A U.S. Census report found in 2000 that 42 percent of American homes used the Internet. The first year the census started tracking U.S. computer usage was 1984.

“The splendors of this age outshine all other recorded ages,” wrote Ralph Waldo Emerson in 1871. “I have seen wrought five miracles—namely, the steamboat, the railroad, the electric telegraph, the application of the spectroscope to astronomy, the photograph.” He died in 1882, missing the invention of the machine gun by three years, the gramophone and radar by five years, and the diesel-fueled internal combustion engine by ten years.

At a meeting of the British Association for the Advancement of Science in 1860, Bishop Samuel Wilberforce asked T.H. Huxley, who came to be known as “Darwin’s Bulldog,” if it was on his grandmother’s or his grandfather’s side that he was descended from a monkey. To which Huxley reportedly replied, “I should feel it no shame to have risen from such an origin; but I should feel it a shame to have sprung from one who prostituted the gifts of culture and eloquence to the service of prejudice and of falsehood.”

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.

After his death in 1665, Pierre de Fermat’s son Clement-Samuel discovered a copy of Arithmetic, a third-century math book by Diophantus, in which Fermat had written on one page, “It is impossible…for any number which is a power greater than the second to be written as the sum of two like powers [xn + yn = zn for n > 2]. I have a truly marvelous demonstration of this proposition which this margin is too narrow to contain.” His son published the note, and “Fermat’s Last Theorem” beguiled mathematicians for over 350 years, until it was proved by Andrew Wiles, with Richard Taylor, in 1995.
