Uh, Right

Decimal arithmetic is a contrivance of man for computing numbers, and not a property of time, space, or matter. It belongs essentially to the keeping of accounts, but is merely an incident to the transactions of trade. Nature has no partiality for the number 10; and the attempt to shackle her freedom with them [decimal gradations], will for ever prove abortive.

— John Quincy Adams, recommending against the metric system in 1821, as reported in Chambers’ Edinburgh Journal, May 15, 1852

All Right, Already

Warring governments can be kind of blunt. James Montgomery Flagg’s famous 1917 “I Want You” recruiting poster (left) echoed an earlier English poster featuring Lord Kitchener, and the Red Army wasn’t any subtler in the 1920s (“Did you volunteer?”).

In the long run, time and patience resolve everything. “When armies are mobilized and issues are joined,” wrote Lao-tzu, “the man who is sorry over the fact will win.”

Never Too Late

If you ever invent a time machine, be sure to head back to the Time Traveler Convention held at MIT on May 7, 2005. (If you’re coming from the far future, MIT was at 42.360007° N, 71.087870° W.)

The convention was covered on the front page of the New York Times, so presumably it’ll be well attended … eventually.

The Quick Brown Fox …

In 1984, British engineer Lee Sallows built a dedicated computer to compose a self-enumerating pangram — a sentence that inventories its own letters. It succeeded:

This pangram contains four a’s, one b, two c’s, one d, thirty e’s, six f’s, five g’s, seven h’s, eleven i’s, one j, one k, two l’s, two m’s, eighteen n’s, fifteen o’s, two p’s, one q, five r’s, twenty-seven s’s, eighteen t’s, two u’s, seven v’s, eight w’s, two x’s, three y’s, & one z.
