Zoom Club Meeting

Description

Welcome to June. June is the month of the Summer Solstice! No sacrifices necessary (best time for that is Winter). This is the time to celebrate (sorry flat earthers) that the earth is a globe and what better way to do that than to walk in the footsteps of Eratosthenes, who as everyone knows, calculated, quite accurately, the circumference of the earth. He was the third head librarian of the library and a real thinker, just like all of you. Now, since the library was destroyed a few years ago (a lot of few years ago), let's just call Alexandria good enough for our meeting.

From American Physical Society News June 2006: (Hey, they say it better than I could.) "Eratosthenes had heard from travelers about a well in Syene (now Aswan, Egypt) with an interesting property: at noon on the summer solstice, which occurs about June 21 every year, the sun illuminated the entire bottom of this well, without casting any shadows, indicating that the sun was directly overhead. Eratosthenes then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle.

He realized that if he knew the distance from Alexandria to Syene, he could easily calculate the circumference of Earth. "

"Easily", did you catch that? That's how good he was!

Now back to our regular programming.
