**Blue Physics** is a free textbook (PDF), released under a Creative Commons license.

It is intended to be a "teach yourself" text for adults, covering first year college physics.

Knowledge of high school algebra is a prerequisite; calculus is taught as needed.

*No* prior knowledge of physics is presumed.

The book has many historical notes and worked examples. Internal references are hyperlinked.

This is a work in progress. The book is projected to cover the following broad topics:

- Mechanics
- Thermodynamics
- Electricity & Magnetism
- Light
- Early Quantum Theory
- Relativity

The current version of 24 June 2014 is 385 pages and 6.46 MB.

(update 14 Oct 2015) I apologize for no updates for a year. I am putting Blue Physics aside until roughly June 2016 to complete, with several colleagues, the typesetting of Sidney Coleman's Lectures on Quantum Field Theory, to appear from World Scientific next summer.
