Textbook chapters: An introduction to modern physics

The aim of these chapters is to provide a mathematically honest derivation of core principles and results, but to depend on figures and diagrams for most definitions and arguments, with minimal algebraic formalism. Math is less likely to prove a barrier than the sometimes inexperienced and ungraceful writing.
