## Overview
**Physics** is the natural [[Science|science]] that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of [[Energy|energy]] and [[Force|force]]. It is one of the most fundamental scientific disciplines; its goal is to understand how the universe behaves, and its discoveries underpin the other natural sciences and most modern technology.
The seven PHYSICS branches span the whole ladder of scales and methods: Particle physics (the smallest constituents), Hydrodynamics (fluids in motion), Yang–Mills theory (the gauge fields behind the forces), Statistical mechanics (micro → macro), Interferometry ([[Wave|wave]]-based precision measurement), Classical mechanics (deterministic motion), and Solid-state physics (matter in the solid phase). Each is a "room" with its own worklist below.

| Hydrodynamics | H | 582 | ✅ 164 selected |

## P — Particle physics
Particle physics (high-energy physics) studies the fundamental constituents of matter and radiation and the interactions between them. Its framework, the **Standard Model**, classifies the fermions (quarks and leptons) that make up matter and the gauge bosons (photon, gluons, W and Z) that carry the electromagnetic, strong, and weak forces, plus the Higgs boson that gives particles mass. Experiments collide particles at high energy in accelerators such as the Large Hadron Collider and reconstruct the short-lived particles produced.
It is an unusually microsimmable branch: the particle zoo is a catalog to browse, scattering and decay are agent-based processes to animate, symmetries are transformations to toggle, and the relativistic wave equations and running couplings are parameter surfaces to explore. **83 articles** selected from the 388 validated candidates, grouped by MicroSim pattern.

## H — Hydrodynamics
Hydrodynamics — broadly **[[Fluid_dynamics|fluid dynamics]]** — describes how liquids and gases flow, governed by the Navier–Stokes equations and organized by dimensionless numbers (above all the Reynolds number) that mark the boundaries between flow regimes. (*Hydrodynamics* redirects to *Fluid dynamics* on Wikipedia.) It is the most target-rich branch in the sheet — **582 validated candidates** — and almost every core concept is a flow field, a tracer cloud, a streamline plot, or a single-slider regime transition.
**164 articles** selected by the quality bar *"can this be shown as an effective interactive MicroSim?"*, grouped by pattern. The dimensionless-number group alone is a near-complete series of parameter sims.

## Y — Yang–Mills theory
Yang–Mills theory is the non-abelian **gauge theory** (built on Lie groups such as SU(2) and SU(3)) that underpins the strong and electroweak forces of the Standard Model; proving it has a mass gap is a Millennium Prize Problem. It is the most abstract branch in the sheet, so the quality bar bites hardest here — people (Yang, Weyl, Faddeev…), journals, and the deep supergravity/superstring tail are omitted. What remains is genuinely microsimmable: **gauge fields on a lattice**, **Lie-group rotations**, **instanton and soliton field configurations**, **symmetry-breaking potentials**, and **running-[[Coupling|coupling]]** curves.

## S — Statistical mechanics
Statistical mechanics derives the macroscopic behavior of matter — temperature, pressure, [[Entropy|entropy]], phase transitions — from the probabilistic motion of its microscopic constituents, via ensembles, the partition function, and the Boltzmann distribution. It is one of the most microsimmable branches in all of physics: an ensemble is a box of agents, a distribution is a live [[Histogram|histogram]], a lattice model is a grid of flipping spins, and a phase transition is an order parameter crossing a threshold.
**111 articles** selected from the 187 candidates (people, textbooks, and off-theme AI/ML pages omitted), grouped by MicroSim pattern. The Ising/Potts lattices and the ensemble/distribution sims are near-automatic series.

## I — Interferometry
Interferometry extracts [[Information|information]] from the **superposition of waves** split along different paths: an interferometer divides a wave, recombines it, and reads the fringe pattern to measure path-length, refractive-index, or timing differences to a fraction of a wavelength. It is the natural home of wave/oscillation MicroSims — two coherent sources and a live fringe field — and the interferometer-type zoo is one schematic engine re-geometried a dozen ways.

## C — Classical mechanics
Classical mechanics describes the deterministic motion of macroscopic bodies under forces — Newton's laws, codified later in the Lagrangian and Hamiltonian formalisms. It is the original home of the dynamical-[[System|system]] MicroSim: a [[Pendulum|pendulum]] swinging, a projectile arcing, planets orbiting, an oscillator tracing its phase portrait. The pool is enormous (**318 candidates**) but heavily padded with Newton biography, his telescopes and estates, and his *numerical-analysis* legacy (Newton's method, Newton [[Fractal|fractal]], Newton–Cotes) — all omitted as people/places or off-theme math.

## S — Solid-state physics
Solid-state physics — the largest branch of condensed-matter physics — explains how the macroscopic properties of solids emerge from atoms in a periodic crystal lattice and the electronic band [[Structure|structure]] that periodicity produces. The MicroSim angle is concrete: a lattice of atoms to build, a band diagram to tune, Bragg diffraction off crystal planes, electrons drifting under a field, bonds as potential wells. The pool is the smallest in the sheet (**77 candidates**) and materials-[[Engineering|engineering]]-heavy, so the set is tighter.

## Microsims
*This section is specific to Wikitube.* [[Physics]] is one of the four flagships of the Matter & Energy Cluster (`_registry/plans/MATTER_ENERGY_CLUSTER_SECTIONS.md`): the sections below follow the Wikipedia pair's skeleton in the pair's order and each carries one three.js microsim from the shared `/matter/` set — built once by its owner flagship, placed wherever the concept recurs. Every sim is pending until the set deploys; the live cards replace these rows through the set generator, never by hand.
