Planck's 1900 Quantum Hypothesis, Step by Step
In late 1900 Max Planck found the formula for black-body radiation and then, to justify it, split energy into chunks of size hν. Here is the sequence of events, the...

Fermions vs Bosons: What Is the Difference?
Every particle in nature is either a fermion or a boson. Fermions, like electrons and quarks, have half-integer spin and obey the Pauli exclusion principle. Bosons, like photons, have integer...

What Is the Born Rule, and Why Is Probability |...
Quantum mechanics describes a particle with a wavefunction ψ, but experiments record definite clicks. The Born rule is the bridge: the probability of finding the particle is the squared magnitude...

Why Does the Periodic Table Have the Shape It D...
The periodic table is not a random grid. Its rows hold 2, 8, 8, 18, 18, 32 and 32 elements because electrons fill shells and subshells, and the Pauli exclusion...

A Feynman diagram is not a photo of particles bouncing around. Each little drawing stands for one term in a calculation of how likely a process is. Here is how...

What Is a Superfluid, and Why Does Helium Climb...
Cool liquid helium below 2.17 kelvin and it turns into a superfluid: it pours through gaps too fine for ordinary liquids, creeps up the walls of its container and can...
