A friendly reminder to USians: if you are planning to vote on Election Day, your mantra is "Nothing I see today convinces me not to go vote."

Exit polls suggest DT cannot be caught? YOU STILL GO VOTE.

Exit polls suggest KH has it in the bag? YOU STILL GO VOTE.

Pundits are saying the country is swinging overwhelmingly red? YOU STILL GO VOTE.

Pundits are saying the country is swinging overwhelmingly blue? YOU STILL GO VOTE.

Polls can be misleading (intentionally or not). The methodology can be biased (or simply poor). Early results may not reflect what the full count will show. There may be a red mirage. NOTHING YOU SEE CONVINCES YOU NOT TO VOTE.

The biggest Democratic win in swing states means nothing if democrats don't turn out everywhere to keep the reliably blue states blue.

VOTE. Wear appropriate weather gear if you think you may have to stand in a line outside (coat, hat, gloves, umbrella, sunhat, whatever, you know where you live). Bring water and a snack and something to do (book, game on your phone, podcast and headphones, whatever, you know what you like). GO VOTE.

NOTHING YOU SEE ON ELECTION DAY CONVINCES YOU NOT TO VOTE.

“NAFTER NOON!”

whitebear-ofthe-watertribe

Every. Time. Every single time. I always get so delighted by this picture set. And I always forget what it’s followed up by. And then I see the “NAFTER NOON!” and absolutely lose it. I’m so glad this post exists.

Ok so this is cool but I always wondered how they knew the shadows were different at the same instant. I mean it is not like they had phones. How did they sync up that instant. I feel like that would be interesting to know but no one ever says.

^^^Does anybody know this one? How, that far apart, the time at which the shadows were observed was synced up? I am genuinely curious, not a goddamn moron asking a gotcha question. High/Low tide? (I live in the middle of the country I do not know for the precise habits of tidal activity.) The appearance of a star (or planet) in the sky? Something as utterly mundane as sunrise?

Well, first of all, it wasn’t actually pillars! Eratosthenes was told about a well in Syene that, in the summer solstice every year (June 21st) would be illuminated at the bottom entirely and without any cast shadows. This indicated that the sun was directly overhead. Going off that well known curiosity and an intelligent hunch, our dude Eratosthenes waited until high noon of the summer solstice to measure the angle of a shadow cast by a stick in Alexandria. (Sidenote: Eratosthenes was a librarian of the infamous Library of Alexandria.)

His next course of action was to hire bematists, surveyors of the time whose professional specialty was to measure distance by walking with equal length steps. They measured a distance between Alexandria and Syene of about 5000 stadia. (Guess where the word stadium comes from.) Once he had that measurement, Eratosthenes did his math-y thing, and there you have it.

ANSWER EVEN COOLER THAN I HOPED!!

Eratosthenes’ work was thorough enough that by the time he finished revising his calculations, he ended up only 66 km off of the actual polar circumference of the Earth, or an error margin of 0.16%. [wiki]
