OnThisDay

On this day in history. One true story a day. Never boring.

On this day in 1910, Titanic's big sister was launched in Belfast, and she'd go on to sink a U-boat. Olympic sailed for 24 years, earned the nickname "Old Reliable" as a WWI troopship, and in 1918 rammed and sank the German sub U-103 in the English Channel. #OnThisDay

Did you know there's a black hole stuck on one note? The one in the Perseus galaxy cluster sends pressure waves through the hot gas around it, and they work out to a B-flat 57 octaves below middle C. A whole piano only covers about 7 octaves.

On this day in 1906, a Brazilian pilot stood in a wicker basket and flew a plane made of bamboo and Japanese silk over a Paris park. Alberto Santos-Dumont's 14-bis went over 50 metres, 3 to 5 metres up, as a crowd watched. #OnThisDay

#OnThisDay in 42 BC, Marcus Junius Brutus, a key conspirator in the assassination of Julius Caesar, took his own life. After losing in battle, Brutus asked his old friends to help him. Supposedly, Strato held Brutus’s sword, upon which he “fell with such force".

Did you know "octopi" isn't really the right plural? Octopus comes from Greek, not Latin, so the -i ending doesn't fit. The Greek-style plural would be octopodes. In English, plain old octopuses wins.

Did you know Uranus basically rolls around the Sun on its side? It's tipped nearly 90 degrees, so instead of spinning like a top it goes round like a rolling ball. No other planet in our solar system is tilted like that.

Ten years later to the day, on 22 Oct 1948, the Haloid Company (later Xerox) announced xerography to the public.

On this day in 1938, the world's first photocopy was made in a rented room in Queens, and all it said was "10.-22.-38 ASTORIA." Chester Carlson's lab used a sulfur-coated zinc plate, a handkerchief and some powder. Over 20 companies, IBM included, turned him down. #OnThisDay

Did you know a sugar cube of neutron star would weigh about a billion tons on Earth? That's roughly a mountain. A neutron star packs about a Sun's worth of mass into a ball about 20 km wide, the size of a city.

On this day in 1959, the Guggenheim opened in New York, and Frank Lloyd Wright wasn't there to see it. He'd died six months earlier. Beforehand, 21 artists signed a letter protesting their work hanging on his spiral ramp. Visitors didn't care: 600 an hour poured in. #OnThisDay

The Library's Liljenquist collection of Civil War photographs contains several images, like these, of veterans who fought for the Union posing with family members (likely their grandsons) who served in World War I.
