The Fermi Paradox

Purported UFO, Passoria, N.J., 1952. Enthusiasts point out that with 250 billion stars in the Milky Way and 70 sextillion in the visible universe, it’s overwhelmingly likely that there are other intelligent, communicating beings out there.

But over a lunch discussion in 1950, physicist Enrico Fermi asked a telling question: “Where are they?” The universe is 13 billion years old, and it’s been estimated that an advanced civilization could colonize our whole galaxy in 5 million years. That’s a flash, as cosmologists reckon time — even if the aliens themselves couldn’t survive an interstellar journey, surely they could design a self-replicating spacecraft that could.

So how come we haven’t met our galactic neighbors? Opinions vary. Maybe we’re in a zoo. Maybe they’re so alien that even detecting them is impossible. Or maybe they don’t believe in us.

Ahem

How to address your betters:

  • Kings: “Your Majesty”
  • Popes: “Your Holiness”
  • Emperors: “Your Imperial Majesty”
  • Presidents: “Your Excellency” (“Mr. President” in the United States)
  • Dukes: “Your Grace”
  • Magistrates: “Your Worship”
  • Judges: “Your Honor”

In 1732, Alexander Pope gave a greyhound to George II. He engraved a couplet on its collar: “I am his Highness’ dog at Kew; Pray tell me, sir, whose dog are you?”

A Clever Landlord

At an humble inn where there were only six rooms, seven travellers applied for lodging, each insisting on having a room to himself. The landlord put the first man in room No. 1 and asked one of the other men to stay there also for a few minutes. He then put the third man in room number two, the fourth man in room No. 3, the fifth man in room No. 4, and the sixth man in room No. 5. Then returning to room No. 1 he took the seventh man and put him in room No. 6. Thus each man had his own room!

La Fornarina

When Raphael died in 1520, a portrait was found in his studio of a local baker’s daughter named Margherita. She is thought to have been his lover — on his deathbead he had bid her farewell and arranged for her care.

The portrait might reveal something else as well. Writing in The Lancet in 2002, Georgetown University medical professor Carlos Hugo Espinel suggests that “La Fornarina” might have had breast cancer:

There is a bulge in the [left] breast that, beginning inward from the axilla and curving horizontally to the right, slopes gently toward the nipple. This bulge seems to be a mass, oval in shape, puckering just above the tip of La Fornarina’s index finger.

After studying other artworks, Espinel has also concluded that Michelangelo had gout, that Rembrandt died of temporal arteritis, and that the Mona Lisa’s smile may have resulted from the partial paralysis of a facial muscle. Independent research has supported some of these diagnoses.

The Steps Experiment

In 1977, Los Angeles freelance writer Chuck Ross submitted a typed manuscript to 14 publishers and 13 literary agents. Ross claimed it was an original work, but in fact it was a freshly typed copy of Jerzy Kosinski’s novel Steps, which had won the National Book Award in 1969.

All 27 recipients failed to recognize Kosinski’s work, and all 27 rejected the manuscript.

Sadly, this is nothing new. From Lippincott’s Monthly Magazine, September 1888:

A disappointed literary aspirant, weary of having his articles declined with thanks, and doubtful of his critics’ infallibility, copied out ‘Samson Agonistes,’ which he rechristened ‘Like a Giant Refreshed,’ and the manuscript, as an original work of his own, went the rounds of publishers and editors. It was declined on various pleas, and the letters he received afforded him so much amusement that he published them in the St. James’s Gazette. None of the critics discovered that the work was Milton’s. One, who had evidently not even looked at it, deemed it a sensational novel; another recognized a certain amount of merit, but thought it was disfigured by ‘Scotticisms;’ a third was sufficiently pleased to offer to publish it, provided the author contributed forty pounds towards expenses.’

The Balloon-Hoax

On April 13, 1844, a curious headline appeared in the New York Sun:

ASTOUNDING NEWS!
BY EXPRESS VIA NORFOLK:
* * * * * * *
THE ATLANTIC CROSSED
IN THREE DAYS!
* * * * * * *
SIGNAL TRIUMPH OF
MR. MONCK MASON’S
FLYING MACHINE!!!

The story told of an amazing 75-hour crossing of the Atlantic by European balloonist Monck Mason, giving extensive details and including a diagram of the craft.

Two days later the Sun printed a retraction, saying that “we are inclined to believe that the intelligence is erroneous” but “we by no means think such a project impossible.”

That compliment would have pleased the hoax writer. His name was Edgar Allan Poe.

Loopy

You can measure a circle’s circumference by “unrolling” it along a line, like this:

circumference fallacy

But note that the smaller circle unrolls at the same time … and it gives the same length. Clearly we could do the same thing with circles of any size. Do all circles have the same circumference?
