Deposition of Elizabeth Brett, a Hertfordshire farmer’s servant, regarding an alarming experience on Sept. 15, 1784:

This deponent, on her oath, saith, that on Wednesday the 15th day of September instant, between four and five o’clock in the afternoon, she, this deponent, being then at work in her master’s brewhouse, heard an uncommon and loud noise, which, on attending to it, she conceived to be the sound of men singing as they returned from harvest-home. That upon going to the door of the house she perceived a strange large body in the air, and, on approaching it in a meadow-field near the house, called Long Mead, she perceived a man in it; that the person in the machine, which she knew not what to make of, but which the person in it called an air-balloon, called to her to take hold of the rope, which she did accordingly; that John Mills and George Philips, labourers with said Mr. Thomas Read, came up soon after, and, being likewise requested to assist in holding the rope, both made their excuses, one of them, George Philips, saying he was too short, and John Mills saying that he did not like it; that this deponent continued to hold the rope till some other harvest-men of Mr. Benjamin Robinson, of High Cross, came up, by whose assistance the machine was held down till the person got out of the machine. And this deponent further, on her oath, saith, that the person now present and shown to her by William Baker, Esq., the justice of peace before whom this deposition is taken, as Mr. Vincent Lunardi, and in her presence declares himself to be Mr. Vincent Lunardi, was the person who called to me from the machine, as above stated, and who descended therefrom in the said field called Long Meadow.

Other witnesses acknowledged that Lunardi had told them “that he had set out from the Artillery Ground in London, a little before two o’clock in the afternoon of the said day, in the machine, and had travelled through the air to the place where they found him.” He later described his view of the city from this new perspective.

The Mindset List

In 1998, Tom McBride and Ron Nief of Wisconsin’s Beloit College began compiling lists of what had “always” or “never” been true in the lives of each incoming class of students, to remind faculty to be mindful of the references they made in class.

For example, that first class, born in 1980, had been 11 years old when the Soviet Union broke up and did not remember the Cold War. They had never had a polio shot and never owned a record player. Their popcorn had always been cooked in a microwave, and they’d always had cable television. Here are some details of the worldview of the class of 2022:

  • Outer space has never been without human habitation.
  • They will never fly TWA, Swissair, or Sabena airlines.
  • The Prius has always been on the road in the U.S.
  • They never used a spit bowl in a dentist’s office.
  • “You’ve got mail” would sound as ancient to them as “number, please” would have sounded to their parents.
  • Mass market books have always been available exclusively as Ebooks.
  • There have always been more than a billion people in India.
  • Films have always been distributed on the Internet.
  • The detachable computer mouse is almost extinct.
  • The Mir space station has always been at the bottom of the South Pacific.

Other recent lists are here.

Gödel’s Loophole

At Princeton in the 1940s, Albert Einstein became a close friend of logician Kurt Gödel, whose incompleteness theorems lie at the heart of modern mathematics. Toward the end of his life Einstein said that his “own work no longer meant much, that he came to the Institute merely … to have the privilege of walking home with Gödel.”

In 1947 Einstein and economist Oskar Morgenstern accompanied Gödel to his U.S. citizenship exam because they were concerned about his unpredictable behavior: During his voluminous preparation for the exam, Gödel said, he had uncovered a flaw in the U.S. constitution that could lead to a dictatorship. Einstein and Morgenstern told him that the exam would really be quite simple and urged him not to prepare so extensively.

At the hearing, judge Phillip Forman asked Gödel:

“Now, Mr. Gödel, where do you come from?”

“Where I come from? Austria.”

“What kind of government did you have in Austria?”

“It was a republic, but the constitution was such that it finally was changed into a dictatorship.”

“Oh! That is very bad. This could not happen in this country.”

“Oh, yes,” Gödel said. “I can prove it.”

“So of all the possible questions, just that critical one was asked by the Examinor,” Morgenstern wrote later. “Einstein and I were horrified during this exchange; the Examinor was intelligent enough to quickly quieten Gödel and say, ‘Oh, God, let’s not go into this.'”

The logician got his citizenship and the friends returned to Princeton. What was the flaw that Gödel had found? There’s no record of it in Morgenstern’s account, so we don’t know. Stephen Hawking suggests that it involved the president’s power to fill vacancies during Senate recesses, and Barry University law professor F.E. Guerra-Pujol conjectures that it might involve the constitution’s power to amend itself. Maybe it’s best if we never discover it.

Deep Thinking

Natural philosopher John Wilkins’ Mathematical Magick of 1648 contains a startling passage in which he foretells the advantages of a long-range submarine, or “ship, wherein men may safely swim underwater”:

  1. ‘Tis private; a man may thus go to any coast of the world invisibly, without being discovered or prevented in his journey;
  2. ‘Tis safe; from the uncertainty of Tides, and the violence of Tempests, which do never move the sea above five or six paces deep. From Pirates and Robbers which do so infest other voyages; from ice and great frosts, which do so much endanger the passages toward the Poles.
  3. It may be of very great advantage against a Navy of enemies, who by this means may be undermined in the water, and blown up.
  4. It may be of a special use for the relief of any place that is besieged by water, to convey unto them invisible supplies: and so likewise for the surprisal of any place that is accessible by water.
  5. It may be of unspeakable benefit from submarine experiments and discoveries.

Wilkins was aware of Cornelius Drebbel’s primitive sub of 1620, but he looks much farther ahead, seeming to foresee combat submarines and deep-sea exploration vessels.

“I am not able to judge what other advantages there may be suggested, or whether experiment would fully answer to these notional conjectures,” he concluded. “But however, because the invention did unto me seem ingenious and new, being not impertinent to the present enquiry, therefore I thought it might be worth the mentioning.”

Face to Face

https://commons.wikimedia.org/wiki/File:Kaname_Harada_0.jpg

Japanese pilot Kaname Harada recalls air combat in World War II:

The initial feeling after shooting down someone was relief, because it was not me who was shot down. My next thought was that I was a better pilot, so I felt superior to the enemy aviator who was shot down. These feelings lasted only for a short time. When we shot at each other, we were at very close range, and during this time I could see my opponent’s face very well. When I saw the enemy’s face, it looked terrible because he was going down. Soon after this I felt very bad, because I could imagine that my opponent had a family of his own, and I killed him. Therefore, to this day I feel very bad about shooting down pilots during the war.

Afterward, when these faces haunted his dreams, Harada became an antiwar activist and even traveled to the United States and Britain to meet some of the pilots he’d fought against. “In general, I have a bad feeling about being involved in the war, and I feel guilty about killing other people in combat,” he said. “I also feel that the war should not have happened in the first place. This is because the governments of countries around the world don’t make an effort to resolve their differences. Instead, they order their armed forces to kill each other. I believe World War II veterans know this best, because we were used as ‘pawns’ by our government to fight a war.”

Missive

In May 1936 a publisher invited Albert Einstein to contribute a message to be sealed in a metal box in the cornerstone of a new library wing in his country home, to be opened a thousand years hence. He sent this:

Dear Posterity,

If you have not become more just, more peaceful, and generally more rational than we are (or were) — why then, the Devil take you.

(From Helen Dukas and Banesh Hoffmann, eds., Albert Einstein, the Human Side, 1979.)

Sea Rules

https://commons.wikimedia.org/wiki/File:General_History_of_the_Pyrates_-_Captain_Bartholomew_Roberts_with_two_Ships.jpg

Articles observed by the crew of Welsh pirate Bartholomew Roberts (1682-1722):

  1. Every man has a vote in affairs of moment; has equal title to the fresh provisions, or strong liquors, at any time seized, and may use them at pleasure, unless a scarcity makes it necessary, for the good of all, to vote a retrenchment.
  2. Every man to be called fairly in turn, by list, on board of prizes because, (over and above their proper share) they were on these occasions allowed a shift of clothes: but if they defrauded the company to the value of a dollar in plate, jewels, or money, marooning was their punishment.
  3. No person to game at cards or dice for money.
  4. The lights and candles to be put out at eight o’clock at night: if any of the crew, after that hour still remained inclined for drinking, they were to do it on the open deck.
  5. To keep their piece, pistols, and cutlass clean and fit for service.
  6. No boy or woman to be allowed amongst them. If any man were to be found seducing any of the latter sex, and carried her to sea, disguised, he was to suffer death.
  7. To desert the ship or their quarters in battle, was punished with death or marooning.
  8. No striking one another on board, but every man’s quarrels to be ended on shore, at sword and pistol.
  9. No man to talk of breaking up their way of living, till each had shared £1,000. If in order to do this, any man should lose a limb, or become a cripple in their service, he was to have 800 dollars, out of the public stock, and for lesser hurts, proportionately.
  10. The captain and quartermaster to receive two shares of a prize: the master, boatswain, and gunner, one share and a half, and other officers one and a quarter.
  11. The musicians to have rest on the Sabbath Day, but the other six days and nights, none without special favour.

That’s from Charles Johnson’s A General History of the Pyrates (1724), via naval historian David Cordingly’s Under the Black Flag (1995). In the early years of the 18th century, Cordingly writes, a pirate captain “had absolute power in battle and when ‘fighting, chasing, or being chased,’ but in all other matters he was governed by the majority wishes of the crew.”

Bullseye

During World War I, British physicist G.I. Taylor was asked to design a dart to be dropped onto enemy troops from the air. He and a colleague dropped a bundle of darts as a trial and then “went over the field and pushed a square of paper over every dart we could find sticking out of the ground.”

When we had gone over the field in this way and were looking at the distribution, a cavalry officer came up and asked us what we were doing. When we explained that the darts had been dropped from an airplane, he looked at them and, seeing a dart piercing every sheet remarked: ‘If I had not seen it with my own eyes I would never have believed it possible to make such good shooting from the air.’

(The darts were never used — “we were told they were regarded as inhuman weapons and could not be used by gentlemen.”)

(From T.W. Körner, The Pleasures of Counting, 1996.)

The Martians

In the first half of the 20th century, a considerable number of famous scientists emigrated from Hungary to the United States, including physicists Eugene Wigner, Edward Teller, and Dennis Gabor and mathematicians Theodore von Kármán, John von Neumann, Paul Halmos, George Pólya, and Paul Erdős. Most were Jewish refugees from Nazi Germany, but they had surprising further similarities — many had been born near Budapest, had shown an early interest in chemistry, and had studied physics at German universities before emigrating to America.

One of their number, Leo Szilard, joked that he knew the reason: They were all descended from a Martian scout force that had landed on Earth in that period. The Martians had left eventually, but not before impregnating some Earth women.

The “Martians” adopted Szilard’s name because in many ways they felt themselves to be outsiders in America: All were brilliant, spoke English with a strong accent, and came from a small little-known country.

When Enrico Fermi posed his famous paradox — if intelligent aliens are as common as we believe, why haven’t we encountered one? — Szilard answered, “They are among us — but they call themselves Hungarians.”
