Isaac Newton’s beer mug resurfaces after 160 years

The secrets of a genius! 😊 I toast to that! Drink more beer!

Isaac Newton’s beer mug resurfaces after 160 years | Royal Society "A scientist and a historian have teamed up to uncork the history of a centuries-old beer mug - or flagon - once owned by Sir Isaac Newton. They also suggest his great work Philosophiæ Naturalis Principia Mathematica (1687) may have been written with his home-made ink in which beer was a key ingredient."

The Secret Side of Sir Isaac Newton

Recommendable! The video gets a few things quite wrong!
E.g. the Lucasian Chair of Mathematics at Cambridge University was not famous because of Stephen Hawking, but because of Newton!

Rediscovering Newton's law with machine learning purely from observational data

Interesting and promising approach! This is only the beginning!

From the abstract:
"... We train a "graph neural network" to simulate the dynamics of our solar system's Sun, planets, and large moons from 30 years of trajectory data. We then use symbolic regression to discover an analytical expression for the force law implicitly learned by the neural network, which our results showed is equivalent to Newton's law of gravitation. The key assumptions that were required were translational and rotational equivariance, and Newton's second and third laws of motion. Our approach correctly discovered the form of the symbolic force law. Furthermore, our approach did not require any assumptions about the masses of planets and moons or physical constants. They, too, were accurately inferred through our methods. Though, of course, the classical law of gravitation has been known since Isaac Newton, our result serves as a validation that our method can discover unknown laws and hidden properties from observed data. More broadly this work represents a key step toward realizing the potential of machine learning for accelerating scientific discovery."

Newton’s Principia may have been more popular than previously thought

Amazing stuff!

Were they really reading and understanding this famous magnus opus or were they just book collectors trying to impress contemporaries? Apparently, the former happened.

"... A 1950s search found only 189 copies of the first edition, published in 1687 under the full title Philosophiae Naturalis Principia Mathematica (SN: 7/4/87). .. [recently] ... unearthed 386 copies, suggesting a more substantial readership. ... By tracking down original owners and studying the annotations that readers made, the researchers conclude that, in addition to scientists, well-educated laypeople were reading the book too. ..."
