Newton, Galileo and Kepler: What Each Got Right...
Kepler found that planets follow ellipses with the Sun at a focus. Galileo built the kinematics of free fall and projectile motion. Newton’s Principia united them under universal gravitation and...

Vera Rubin and W. Kent Ford’s 1970 Andromeda survey mapped how orbital speed changes with radius. Outer stars move too fast for the visible mass alone. Whether that means dark...

Faraday, Maxwell and Tesla: Who Did What in Ele...
Electromagnetism was not one inventor’s story. Faraday made induction a laboratory fact, Maxwell turned fields into equations that predicted light, and Tesla patented a practical AC motor. Here is who...

Stephen Hawking: What Did He Predict, and What ...
Hawking’s 1974 prediction that black holes radiate is central theoretical physics — and still unobserved in astrophysical black holes. Analogue experiments are not detections. The information paradox is open. Penrose’s...

Who Started Quantum Mechanics? Planck, Bohr and...
Quantum theory did not begin with one paper. Planck quantized energy in 1900, Bohr quantized the atom in 1913, and Heisenberg’s 1925 matrix mechanics plus the 1927 uncertainty relation made...

Did Cecilia Payne Discover What Stars Are Made Of?
Cecilia Payne’s 1925 thesis showed that stars differ mainly in temperature, not composition, and that hydrogen and helium vastly outnumber everything else. She then called that result “almost certainly not...
