Uninspiring land speed records:

  • 39.24 mph, Dec. 18, 1898, Gaston de Chasseloup-Laubat (France)
  • 41.42 mph, Jan. 17, 1899 Camille Jenatzy (Belgium)
  • 43.69 mph, Jan. 17, 1899 Gaston de Chasseloup-Laubat (France)

Interestingly, these were all set with electric vehicles.

The Turk

People were willing to believe in a chess-playing automaton as early as 1769. That’s when Wolfgang von Kempelen unveiled “The Turk,” a cloaked and turbaned robot that played over a maplewood cabinet full of clockwork. The contraption toured the courts of Europe, where it beat Benjamin Franklin and Charles Babbage, among many others.

The machine’s secret emerged only in 1854, after the automaton was destroyed in the great Philadelphia fire. The cabinet had contained a human player who followed the game by watching magnets on the board’s underside. He made his moves on a secondary board that transmitted them to the Turk.

Still, it played some good games. Here it beats the crap out of Napoleon Bonaparte, who has White:

A Spaceborne Time Capsule

You can write a message to future generations at the KEO project. It’ll be launched on a satellite that won’t return to Earth for 50,000 years.

Even more ambitious is the LAGEOS satellite, which will re-enter our atmosphere in 8.4 million years bearing a plaque that shows the arrangement of the continents. Let’s hope our descendants still have catcher’s mitts.

Luddite by Degrees

Douglas Adams’ “rules that describe our reactions to technologies”:

  1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.
  2. Anything that’s invented between when you’re 15 and 35 is new and exciting and revolutionary and you can probably get a career in it.
  3. Anything invented after you’re 35 is against the natural order of things.

Watch Your Step

Vaucanson’s Shitting Duck was one of the more unsavory products of the French Enlightenment.

When it was unveiled by Jacques de Vaucanson in 1739, thousands watched the “canard digérateur” stretch its neck to eat grain from a hand. The food then dissolved, “the matter digested in the stomach being conducted by tubes, as in an animal by its bowels, into the anus, where there is a sphincter which permits it to be released.” These inner workings were all proudly displayed, “though some ladies preferred to see them decently covered.”

Why make fake duck shit when the world is so well supplied with the real thing? It was part of the Enlightenment’s transition from a naturalistic to a mechanical worldview. Suddenly a duck was not a God-given miracle but a machine made of meat, and complex automatons carried the promise of mechanized labor, stirring a cultural revolution.

Goethe mentioned Vaucanson’s automata in his diary, and Sir David Brewster called the duck “perhaps the most wonderful piece of mechanism ever made.” Sadly, the whole thing was a fake: The droppings were prefabricated and hidden in a separate compartment. Back to the drawing board.

Why Is a Manhole Cover Round?

Actual questions asked in Microsoft job interviews:

  • How are M&Ms made?
  • Suppose you had eight billiard balls, and one of them was slightly heavier, but the only way to tell was by putting it on a scale against another. What’s the fewest number of times you’d have to use the scale to find the heavier ball?
  • Why do you want to work at Microsoft?
  • One train leaves Los Angeles at 15 mph heading for New York. Another train leaves from New York at 20 mph heading for Los Angeles on the same track. If a bird, flying at 25 mph, leaves from Los Angeles at the same time as the train and flies back and forth between the two trains until they collide, how far will the bird have traveled?
  • How many gas stations are there in the USA?
  • You’ve got someone working for you for seven days and a gold bar to pay them. The gold bar is segmented into seven connected pieces. You must give them a piece of gold at the end of every day. If you are only allowed to make two breaks in the gold bar, how do you pay your worker?
  • The interviewer hands you a black pen and says nothing but “This pen is red.”
  • Pairs of primes separated by a single number are called prime pairs. Examples are 17 and 19. Prove that the number between a prime pair is always divisible by 6 (assuming both numbers in the pair are greater than 6). Now prove that there are no “prime triples.”

At the end they ask, “What was the hardest question asked of you today?” My answer: “Why do you want to work at Microsoft?”
