To understand how quantum theory emerged, one must first appreciate the towering elegance and eventual fragility of classical physics. For two centuries, scientists had lived under the comforting dome of Newton’s laws, which described the heavens and Earth with the same mechanical precision. Maxwell...

From Quantum: Einstein, Bohr and the Great Debate About the Nature of Reality

Einstein’s pursuit was always one of clarity, coherence, and realism. For him, the world existed independently of our observation. Physics, he insisted, must describe that world, not the limits of our perception of it. Bohr, by contrast, saw in quantum theory a profound lesson about those very limit...

From Quantum: Einstein, Bohr and the Great Debate About the Nature of Reality

At the close of the nineteenth century, classical physics seemed invincible. Everything — from planetary motion to heat radiation — could be explained by the known laws. Yet one stubborn anomaly remained: the spectrum of light emitted from heated bodies. The so‑called blackbody radiation problem def...

From The Quantum Story: A History in 40 Moments

If Planck cracked open the door, Einstein stormed through it. In 1905, while employed at the Swiss Patent Office, he published four papers that would change physics forever. One of those papers tackled a puzzling phenomenon: when light shines on certain metals, electrons are ejected from the surface...
