He did not begin with answers. He began by refusing to accept that the obvious description of the world was complete — riding a beam of light in his head, falling in an elevator, asking what a clock would say if you ran beside it. Every card in this league is one of his questions, handed on.
What he got right
Photoelectric effect, 1905. Light arrives in quanta — the work that won the 1921 Nobel, not relativity.
Special relativity, 1905. Time and length depend on the observer; the speed of light does not.
General relativity, 1915. Gravity is the shape of spacetime, confirmed by the 1919 eclipse.
E = mc², 1905. Mass is energy; the most quoted equation in physics.
Brownian motion. Gave atomic theory a measurable proof.
What he got wrong
Entanglement. He called it spooky action at a distance and spent years arguing it could not be real. Bell's theorem (1964) and the loophole-free tests (2015) settled it against him.
The cosmological constant. Added to hold the universe still, then reportedly called his greatest blunder. It turned out to be real — dark energy.
Quantum indeterminacy. "God does not play dice" — the evidence says otherwise.
“Spooky action at a distance.”
Letter to Max Born, 1947 — the objection he lost
“I rarely think in words at all.”
Reply to Hadamard's questionnaire, 1945
“Imagination is more important than knowledge.”
Interview with G. S. Viereck, 1929
