A white dwarf has no fusion left to hold it up. What stops it collapsing is electron degeneracy pressure: the Pauli exclusion principle forces electrons into ever-higher momentum states as...

Decoherence is what happens when a quantum system becomes entangled with its surroundings: interference between its alternatives becomes practically invisible. It explains why we never see a pointer in two...

A Bose–Einstein condensate is a dilute gas of bosons cooled until a macroscopic number share the same quantum ground state. Bose’s 1924 photon statistics and Einstein’s extension set the idea;...

What Is the Spin–Statistics Theorem?
The spin–statistics theorem ties a particle’s spin to the symmetry of its quantum state. Integer spin → bosons (symmetric); half-integer spin → fermions (antisymmetric). Fierz (1939) and Pauli (1940) made...

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...

Why Do Electrons Have Spin ½? What Spin Is, and...
Electrons carry an intrinsic angular momentum of ½ in units of ħ. It splits beams of atoms in two, makes electrons need two full turns to come back to themselves,...
