How Julia Robinson helped define the limits of mathematical knowledge:

Inspiring story.

Robinson never thought of herself as a brilliant person. In reflecting on her life, she focused instead on the patience that served her so well as a mathematician, which she attributed in part to a period of intense isolation as a child. At age 9, while living with her family in San Diego, she contracted scarlet fever, followed by rheumatic fever.

Penicillin had just been discovered and was not yet available as a treatment. Instead, she lived at the home of a nurse for a year, missing two years of school.

First Photo of the Lunar Farside


The far side of the Moon is surprisingly different. The most striking difference evident in the Luna 3 pictures is the absence of the large, dark seas of cooled lava, called maria, that cover a substantial fraction of the Earth-facing near side. The far side is instead densely peppered with impact craters of every size and age.

Remembering Murray Gell-Mann (1929–2019), Inventor of Quarks—Stephen Wolfram Blog:

A nice weekend-reading. Murray Gell-Mann as seen by Stephen Wolfram (guest stars: Richard Feynman, George Zweig, Steve Jobs and S. Wolfram himself of course). A very interesting essay at several levels, much more than a typical obituary.

On this day a century ago, General Relativity was experimentally confirmed for the first time.

Today, the treadmill is one of the most common ways to get in your weekly workout, but did you know that in the 1800s, treadmills were created to punish English prisoners?

The original version was invented in 1818 by English engineer Sir William Cubitt. While the prisoners stepped on 24 spokes of a large paddle wheel, the rotation made gears pump out water,  crush grain, or power mills, which is where the name “treadmill” originated.
