More of the ongoing weirdness of modern physics: "In some versions of quantum gravity, time itself condenses into existence."
"To help support everyone during Covid-19, Springer has released a ton of free textbooks."
Obviously not the most recent books, but may well be worth a minute or two to look. I downloaded a couple.
"But along with this new, counterintuitive picture of reality, many myths and misconceptions have arisen. Here's the true science behind 10 of them."
Apparently, even some of Big Al's unpublished work was amazing.
A nice concise statement from Dr. Hossenfelder of what she thinks has gone wrong in the last several decades of theoretical physics and how physicists might fix the problem.
Still more extreme weirdness from modern physics.
"The Physics Travel Guide is an expository wiki which explains concepts in three levels of difficulty. We call these levels: intuitive, concrete and abstract."
Sabine Hossenfelder presents an interesting problem in inference that I hadn't heard before.
Yeah, it seems like the odds are really lousy. But a few other inventors have faced very long odds, too.
The Hubble Deep Field. It's quite simply astonishing--there's no other word for it.
