Why philosophy of physics?
Some physicists reject philosophy as a distraction from ‘real’ science but it is in fact both useful and beautiful

Epic Effort to Ground Physics in Math Opens Up the Secrets of Time
By mathematically proving how individual molecules create the complex motion of fluids, three mathematicians have illuminated why time can’t flow in reverse.

If you haven't muted me yet, here's a debunking of John Bell's "Heart attacks in Lille and Lyon".
Bell tells us the same logic applies to heart attack rates in Lille and Lyon as does to EPR-B, so he can ignore the rules of probability theory. Because, he says, neither city's causal influences can AFFECT the other's.
Note we are writing PROBABILITY THEORY. What can AFFECT does not matter—it is what is CORRELATED that matters!
So a counterexample is trivial to make...

Cosmic ceilidh
Hundreds of scientists are set to perform a new Scottish country dance inspired by the ripples in spacetime whose existence was first theorised by Albert Einstein.
Researchers from the University of Glasgow teamed up with the culture and research organisation Science Ceilidh to develop a dance to mark the 10th anniversary of the historic first detection of gravitational waves.

Imaginary numbers are real
These odd values were long dismissed as bookkeeping. Now physicists are proving that they describe the hidden shape of nature

"Games are not physics engines. They are experiences. And racing games, more than many others, deliberately manipulate reality to deliver those experiences."
A quote from this great article by @wassimulator, dealing on core building blocks of vehicle physics simulation in video games.

Awesome overview on the subject, even for folks not working physics code but on car games. Love it! 😍
Happy birthday to #physicist Harriet Brooks (1876 - 1933) who discovered atomic recoil, Radon & recognized radioactive elements could undergo chains of transmutations into a series of new elements. #nuclear #physics
She was Rutherford’s 1st grad student at McGill. After publishing her results in 1899 she completed her MSc in 1901 on “Damping of Electrical Oscillations,” before embarking on #radioactivity research. 🧵

This month's Distributed Proofreaders blog delves into the newly uploaded "Newton's Principia."
"In it, Newton expounds, with mathematical proof, what is now the bedrock of modern physics: his groundbreaking laws of motion and universal gravitation, and his explanations of the motion of planets, moons, comets, tides, fluids, and other physical phenomena."
