Easy as Pi

Isaac Asimov proposed this mnemonic for a famous constant:

How I want a drink, alcoholic, of course, after the heavy lectures involving quantum mechanics!

Count the letters in each word and you’ll get 3.14159265358979.

The bitterest thing in the world is denatonium, a compound discovered by Scottish researchers in 1958. Most people find its taste unbearable even in dilutions of 10 parts per million.

A New York chemist once went home with a trace of denatonium saccharide on his lip. He kissed his wife and she almost threw up.

The Eye of Sauron

The Eye was rimmed with fire, but was itself glazed, yellow as a cat’s, watchful and intent, and the black slit of its pupil opened on a pit, a window into nothing.

That’s a quote from The Fellowship of the Ring, but this image is actually a star. Fomalhaut, 25 light-years away, is one of the brightest stars in the night sky.

Draw your own conclusions.

Hexakosioihexekontahexaphobia is fear of the number 666, which is linked to Satan and the Antichrist in the Book of Revelation.

Unfortunately, it’s rather hard to avoid. 666 is the sum of the squares of the first seven primes:

666 = 22 + 32 + 52 + 72 + 112 + 132 + 172

Also:

666 = 1 + 2 + 3 + 4 + 567 + 89

= 123 + 456 + 78 + 9

= 9 + 87 + 6 + 543 + 21

= 13 + 23 + 33 + 43 + 53 + 63 + 53 + 43 + 33 + 23 + 13

In 1989, after his second term as president, Ronald and Nancy Reagan moved to a new home in the Bel-Air section of Los Angeles. They had the address, 666 St. Cloud Road, changed to 668 St. Cloud Road.
