The first free comprehensive textbook on quantum (and classical) field theory. The approach is pragmatic, rather than traditional or artistic: It includes practical techniques, such as the 1/N expansion (color ordering) and spacecone (spinor helicity), and diverse topics, such as supersymmetry and general relativity, as well as introductions to supergravity and strings.

Superspace, or One thousand and one lessons in supersymmetry is available in pdf format. We beg our readers’ indulgence. We have tried to present a subject that we like, that we think is important. We have tried to present our insights, our tools and our knowledge. Along the way, some errors and misconceptions have without doubt slipped in.
A companion book with exercises (electrodynamics problems with solutions) is available for The Electromagnetic Field Theory Textbook.
Written with the advanced undergraduate or graduate student in mind, Electromagnetic Field Theory is a textbook on the theory of electrodynamics, at roughly the same level as the well-known textbooks by Jackson and Panofsky&Phillips.
Event-Symmetric Space-Time presents a startlingly integrated world view from the forefront of physics. In a style which mixes technical notes with clear expositions, Event-Symmetric Space-Time will be of interest to researchers in physics and interested non-professionals alike.
“Introduction to String Field Theory” by Warren Siegel is available in several formats without charge.
Physics Study Guide is a free online physics book from Wikibooks, the open-content textbooks collection. This guide is meant as a supplement to a year long freshman level physics course with a trigonometry prerequisite. Some ideas from calculus are included in the book but are not necessary to understand the content.
“A Heat Transfer Textbook”, by 4th edition John H. Lienhard IV, Professor, University of Houston and John H. Lienhard V, Professor, Massachusetts Institute of TechnologyThis textbook is an introduction to heat and mass transfer oriented toward engineering students.
“A 21st Century Frontier of Discovery: The Physics of the Universe” is a free pdf ebook from NASA. The Interagency Working Group on the Physics of the Universe (IWG) presents its conclusions on the actions necessary to implement the recommendations of Connecting Quarks with the Cosmos: Eleven Science Questions for the New Century, a 2002 report of the National Research Council.
While usual presentations of physical theories emphasize the notion of physical quantity, this book shows that there is much to gain when introducing the notion of physical quality. Download it free of charge in pdf format.
