📅 October 9, 1874 — The Founding of the Universal Postal Union

A mailman in Berne said, “Let’s try
To send letters ‘cross borders — and why
Should each country’s own rate
Make the postman wait?
One union means mail can now fly!”

1911-1913: The Hertzsprung-Russell diagram, a log-log plot of luminosity as a function of temperature for stars
Not so beautiful as a plot, but those red giants catch the eye.
💥Revolutionized stellar physics

The original Hertzsprung-Russell diagram, a log-log plot of luminosity as a function of temperature. A cluster of points is circled in the upper right which violated the otherwise linear relationship of the main sequence ; these proved to be the Red Giants

Modern rendition of the H-R diagram, with named clusters identified

📅 October 8, 1871 — The Great Chicago Fire

A cow town called Chicago one night,
On October the eighth caught alight,
Mrs. O'Leary's old barn
Sparked a fiery yarn—
Three days burned till the city lost sight!
