Beautiful physics

Another great find from Brain Pickings, the French mathematician and journalist Amédée Guillemin and his 1868 physics textbook Les phénomènes de la physique.

How nature works, in stunning psychedelic illustrations of scientific processes and phenomena from a 19th-Century French physics textbook
In consonance with the pioneering 19th-century information designer Emma Willard’s conviction that knowledge is most readily received when “addressed to the eye,” Guillemin understood that the fundamental laws of nature appear too remote and slippery to the human mind. To make them comprehensible, he had to make their elegant abstract mathematics tangible and captivating for the eye.

He had to make physics beautiful.

I’d say he succeeded, wouldn’t you?

Don’t mess with golf balls

Have you ever wondered what would happen if you had a golf ball that doubled in density every hour?

How long would you have before you ran into trouble if you were given a golf ball that doubled in density once an hour?
3PM: It took nearly 4 full days, but we’ve finally arrived: The golf ball actually weighs just a bit more than the Earth does, now. Almost everyone is incapable of moving. Trees are falling down, as are buildings. There are massive earthquakes, tsunamis, and volcanic eruptions.

4PM: Gravity is 3g. Humans that are left alive are gasping for breath on the surface. That is, if they haven’t been engulfed by lava. Earth is starting to shrink. Air pressure is going up, and the Moon is coming for us.

Needless to say, it doesn’t end well.
