Leonardo da Vinci & Albert Einstein: Could the Renaissance Genius Have Grasped the Foundational Concepts of General Relativity?

The article “Leonardo da Vinci’s Visualization of Gravity as a Form of Acceleration,” published in the aptly named journal Leonardo (peer-reviewed, MIT Press Direct), has gained some fame, as it has appeared in many news articles. The authors claim that Leonardo understood gravity almost as well as Newton, and even suggest that he anticipated Einstein’s equivalence principle. José María González Ondina presents a more likely interpretation, based on Leonardo’s own manuscripts, that negates these incredible claims.

Suzie Sheehy — The Matter of Everything: How Curiosity, Physics, and Improbable Experiments Changed the World

Shermer and Sheehy discuss: what it’s like being a female physicist in a mostly male field • Does science progress through falsification, confirmation, consensus, or Bayesian reasoning? • atoms, light, Higgs Boson, time, gravity, dark energy, dark matter, string theory, radioactivity • Gold Foil Experiment • cloud chambers • particle accelerators • splitting the atom • Is there a place for God in scientific epistemology? • Is math all there is? Is math universal? • other universes, dimensions, and the multiverse.

Black Holes Sing: Black Holes, Their Orbits & Gravitational Waves

Black Holes are the ultimate death state of very massive stars. Collapsing under their own weight, the dead cores will curve spacetime so strongly that not even light can escape. Black holes emit no light and reflect no light. They are dark against a dark sky and effectively invisible. When two black holes move in orbit around each other, they churn up the spacetime around them, emanating waves in the fabric of space itself…
