Skills: Techniques and Methods for Physics

Purpose

The skills namespace contains practical how-to knowledge for doing physics. Calculations, simulations, data analysis, lab techniques, and the methods that enable research.

Why This Namespace Exists

Knowing physics concepts isn't enough — you need to know how to do physics. This namespace captures the practical skills that enable research and understanding.

Mathematical Techniques

• Series expansions and asymptotic analysis
• Perturbation methods (regular and singular)
• Green's functions and integral equations
• Complex analysis in physics (contour integration, residues)
• Special functions (Bessel, Legendre, Hermite, Laguerre)
• Fourier analysis and transform methods
• Tensor calculus and differential geometry
• Group theory applications (SU(2), SU(3), Lorentz group)

Numerical Methods

• Monte Carlo integration and sampling
• Molecular dynamics simulations
• Density functional theory basics
• Lattice gauge theory methods
• Solving PDEs numerically (finite difference, finite element)
• Optimization and root-finding algorithms
• Eigenvalue problems and diagonalization

Data Analysis

• Statistical fitting (least squares, maximum likelihood)
• Hypothesis testing and confidence intervals
• Principal component analysis
