The Pauli matrices are used to study the angular momentum of spin-1/2 particles. I won't merely tell you what they are: I'll work them out from scratch, and in…
Standard Model - Part 6: Pauli Matrices

The physics and math of spin-1/2 particles: how states of a spin-1/2 correspond to points on a sphere. The images of the Stern-Gerlach experiment from Wikicommons are…
Standard Model - Part 5: Spin-1/2 particles

What holds the protons and neutrons together in the nucleus? Early work on this question combined Heisenberg's idea that the proton and neutron are two states of…
Standard Model - Part 7: Pions

A crash course in quantum physics. I explain states and transition probabilities between states in quantum physics, and the basic rule for computing transition…
Standard Model - Part 4: Quantum Physics

A first tour of quantum mechanics and how the 3 forces in the Standard Model are connected to quunits, qubits and qutrits. How qubits differ from classical bits and…
Standard Model - Part 3: Qubits

The physics leading up to the Standard Model - starting from the three pillars of physics in the 1800s and the paradoxes they led to.
Standard Model - Part 2: The Big Ideas

A white hole is a purely hypothetical time-reversed black hole. What does general relativity say about them? Would they repel you? Could you fall into a white hole -…
