Bell’s Theorem Explained: How We Know Quantum W...
Einstein suspected quantum mechanics was missing hidden instructions. In 1964 John Bell found a way to test that idea, and experiments from 1972 to 2015 settled it against local hidden...

What Is Zero-Point Energy? Why Nothing Is Ever ...
Cool anything to absolute zero and quantum physics still will not let it stop moving. The leftover energy, ħω/2 for every oscillator, is called zero-point energy. Here is where it...

Berry Phase: The Phase a Quantum State Picks Up...
Carry a quantum state slowly around a closed loop and it comes back with an extra phase that depends only on the shape of the loop, not on how long...

The Hanbury Brown–Twiss Effect: Why Photons Bunch
Light from a star arrives in clumps: photons are more likely to show up together than a random stream would allow. Here is how two radio astronomers found the effect,...

The Bohr Model: How Hydrogen's Light Was Decoded
In 1913 Niels Bohr explained hydrogen's spectral lines with two bold rules. Here is how the Bohr model works, the numbers it gets exactly right, and the places where it...

Bose Statistics: How a 1924 Paper Changed Counting
In 1924 a physicist in Dhaka rederived Planck's radiation law by counting light quanta in a new way. Einstein translated the paper, extended it to atoms, and predicted a new...
