You’re in a dark room. The only light comes from an old LED digital alarm clock with four seven-segment displays. The time is displayed in 24-hour format, HH:MM (no seconds), and the leading digit is blank if not used. How much time passes between the room’s darkest state and its lightest?

Obstacle Course
In Aldiborontiphoskyphorniostikos, a Christmas party game from 1824, players had to take turns reading tongue-twisting passages as quickly as possible from a prepared list. Each passage represents a letter of the alphabet, and each builds on its forerunners. The worst is this:
TOBY PHILPOT sat tippling with UMPO, VUMPO, and WILLY WIDEMOUTH of Wolverhampton, when X and Y, two officers, brought in the culprit, while Saccharum Sweet Tooth said nothing, while Ramo Samee really swollowed a sword, while Sly Kia cried Quack! quack! quack! And turned into a duck, to escape from Poniatowsky, who said, To jail with the Juggler and Jade, as Mother Bunch on her broomstick cried, here’s a to-do! as Nicholas Hotch-potch said, Never were such times, as Muley Hassan, Mufti of Moldavia, put on his Barnacles, to see little Tweedle gobble them up, when Kia Khan Kreuse transmogrofied them into Pippins, because Snip’s wife cried, Illikipilliky! lass a-day! ’tis too bad to titter at a body, when Hamet el Mammet, the bottlenosed Barber of Balasora, laughed ha! ha! ha! on beholding the elephant spout mud over the ‘Prentice, who pricked his trunk with a needle, as Dicky Snip, the tailor, read the proclamation of Chrononhotonthologos, offering a thousand sequins for taking Bombardinian, Bashaw of three tails, who killed Aldiborontiphoskyphorniostikos.
A player who couldn’t pronounce a passage perfectly had to pay a penalty for each mistake. Here’s the whole list.

Bells tolled,

Small Talk
“A Brief and Somewhat Ungracious Exchange Between the British Ambassador’s Wife, Who Speaks No Spanish, and the Spanish Ambassador’s Wife, Who Speaks No English, During a Courtesy Call by the Latter Upon the Former: Written on the Assumption That My Readers Know the Sound of the Spanish Word for ‘Yes'”

Letters and Numbers
ONE + TWO – THREE – FOUR + FIVE = 1
That’s true if we replace each word either with the number it denotes or with the quantity of its letters: Either way we’re left with 1. Another:
ONE + TWO – THREE – FOUR + FIVE – SIX + SEVEN + EIGHT + NINE – TEN + ELEVEN + TWELVE – THIRTEEN – FOURTEEN = 5
These are the only two such sequences using 20 or fewer consecutive number names, found Leonard Gordon, although other sequences of plus and minus signs are possible.
In a separate but related project, Gordon assigned the number names ONE through FIFTEEN, ONE through NINETEEN, and ONE through TWENTY to either side of an equals sign so that the denoted equation is mathematically correct and each equation “balances,” with the same number of letters on each side:
ONE + FOUR + SEVEN + TEN + ELEVEN + THIRTEEN + FOURTEEN = TWO + THREE + FIVE + SIX + EIGHT + NINE + TWELVE + FIFTEEN
ONE + THREE + FIVE + SEVEN + NINE + SIXTEEN + SEVENTEEN + EIGHTEEN + NINETEEN = TWO + FOUR + SIX + EIGHT + TEN + ELEVEN + TWELVE + THIRTEEN + FOURTEEN + FIFTEEN
ONE + THREE + SIX + NINE + TEN + TWELVE + THIRTEEN + FIFTEEN + SEVENTEEN + NINETEEN = TWO + FOUR + FIVE + SEVEN + EIGHT + ELEVEN + FOURTEEN + SIXTEEN + EIGHTEEN + TWENTY

Nowheresville

In September 2008, Mike Nolan, head of web services at Edge Hill University in Ormskirk, England, noticed something strange on Google Maps. “I grew up in the area and spotted on the map one day that it said ‘Argleton’,” he told the Guardian. “But it’s just a farmer’s field close to the village hall and playing fields. I think a footpath goes across the field, but that’s all.”
Bloggers began to discuss the nonexistent town, which found its way into other services that used Google’s data: Employment agencies, weather services, and letting agents began to cite Argleton in their listings, reassigning real people and businesses to the phantom settlement because of its claimed location.
Was it a joke? A placeholder? A misspelling? Whatever it was, it had disappeared again by May 2010. Google would say only that it experiences “occasional errors” and that it gets its mapping information from a Dutch company called Tele Atlas (whose spokesperson would add only, “I really can’t explain why these anomalies get into our database”).
Danny Dorling, president of the Society of Cartographers, said, “I would bet that this is an innocent mistake. In other words, it was not intentionally inserted to catch out anyone infringing the map’s copyright, as some are saying. But the bottom line is that we don’t know what mapping companies do to protect their maps or to hide secret locations, as some are obligated to do.”
