I asked ChatGPT to determine the physical distance from the event horizon of a Schwarzschild black hole in term of standard coords and the answer it gave had only one silly calculational error (on a senior undergrad quiz would have earned an A-). Impressive.

Love this, even though I disagree: "Either mathematics is too big for the human mind, or the human mind is more than a machine."--Kurt Gödel, among the greatest logicians of all time, died OTD 1978.

Here's one shocking thing about quantum mechanics: As a particle travels, it explores every possible path, and what we observe is a particular melding of them all.

To my mind, the biggest unsettled question in Quantum Mechanics is: How does the wavy probabilistic haze central to the mathematical formulation of the theory transform into the single definite reality of experience?

If you could travel to the past, you would not change anything. You would have always been part of that time. There are not two versions of a moment in time, one without you and one with you. Moments in time just ARE. They don't change.

The sun is not just a source of energy. It's a source of low entropy--highly ordered--energy. That’s what's essential in making the sun's energy useful.

This week in 1915: Albert Einstein completes the general theory of relativity, giving us one of the most beautiful equations ever conceived (LHS describes the curvature of spacetime, RHS describes the matter and energy in spacetime).
