Physics (also known as "natural philosophy") is the analysis of nature that is conducted in order to __ model__ phenomena to describe how the universe behaves and gain partial understanding of it. One must keep in mind that physical laws and theories are never

*proven*nor

*refuted*but examined on how well they are in agreement to observations and in what domain of physical parameters (speed, temperature, pressure, field strength, etc) they remain in acceptable agreement with experimental observations. While it may be very tempting to assume our equations are the unbreakable rules or source code of the universe, we must realize that such absolute knowledge is fundamentally and hopelessly unknowable.

## High School[]

High school/Freshman physics is a broad survey of the fundamentals of physics: Kinematics and Mechanics, Waves and Acoustics, Thermodynamics, Electricity and Magnetism, Optics and Light, Special Relativity, and Quantum Mechanics which may or may not be done in that order and may have a brief superficial discussion of further topics like Solid-State, Nuclear, or Particle Physics. The mathematical prerequisite is just Precalculus/Trigonometry but with the assumption you are at least taking the Calculus sequence at the same time as a co-requisite and topics from calculus will steadily appear as you progress. Of course, already knowing some calculus ahead of time will be an added benefit.

- Young and Freedman - University Physics with Modern Physics

The following are "honors" level alternatives to the above tome but they don't quite cover everything (such as fluids and other small topics) so be aware to supplement them if you insist on studying out of them. Alternatively, you can use them for additional practice and insight with the above text (but don't feel obligated to read them before moving on to undergraduate level books). The level of required math is a bit higher and assumes you already know calculus.

- Kleppner & Kolenkow - An Introduction to Mechanics
- Purcell & Morin - Electricity and Magnetism
- Georgi - The Physics of Waves
- Fermi - Thermodynamics (Dover Books on Physics)
- Eisberg & Resnick - Quantum Physics of Atoms, Molecules, Solids, Nuclei, and Particles

## Undergraduate[]

The essential mathematical prerequisites are Vector Calculus, Matrix Algebra, and Ordinary Differential Equations. You're also assumed to be concurrently learning Partial Differential Equations, Probability, Fourier Transforms, Complex Variables, Special Functions, and Calculus of Variations as you progress. Most books will tend to have some brief introductory remarks on them when needed but it will only cover just enough material to solve the chapter's problems and are really designed to serve as motivation to go out and fully learn them. The more math you know in advance, the clearer the material will be.

Beyond these topics, physics majors are expected to take a number of labs and seminar courses covering Error Analysis, Electronics and Instrumentation, Scientific Integrity (You might think it's unlikely but fraud in physics research does happen. The most famous example being Jan Hendrik Schön who was once thought to be on his way to the Nobel Prize in Physics with completely fraudulent fabricated research), and Experimental Modern Physics.

Sooner or later, physics majors pick up a computer algebra system like Maple, MuPAD (Matlab's Symbolic Math Toolbox), Mathematica, or Python + SymPy to help symbolically solve tricky problems. Similarly, depending on what field and research they pursue, they also learn programming in C++, Fortran, Matlab, Python, IDL and/or LabVIEW as well as others. If you're aiming to get familiar with programming before you need it, it's recommended to start with C++ and learning data structures. While data structures aren't often used for computational physics work, they make excellent subject matter for practice material.

__Supplemental Reading__[]

- Feynman - Lectures on Physics (Supplement for insight into physics)
- Joos - Theoretical Physics (Dover Books on Physics)

__Classical Mechanics__[]

- Taylor - Classical Mechanics (Great for self study and contains a nice chapter on SR)
- Gregory - Classical Mechanics (More to the point than Taylor)
- Woodhouse - Introduction to Analytical Dynamics (Mathematical oriented complement to the above)
- Sussman and Wisdom - Structure and Interpretation of Classical Mechanics
- Sussman has also authored the classical computer science text, Structure and Interpretation of Computer Programs. The book takes an idiosyncratic approach to classical mechanics that uses the functional programming language Scheme to program various equations, and asks students to do the same, as a conceptual aid to eliminate ambiguity from traditional mathematical notation. The book is freely available here in HTML format. Related materials may be found here.

__Special Relativity__[]

- Taylor and Wheeler - Spacetime Physics: Introduction to Special Relativity (Low level but good for conceptual understanding)
- Woodhouse - Special Relativity (Nice brisk mathematical treatment of SR. See also Woodhouse's General Relativity book for a continuation)
- Wolfgang Rindler - Introduction to Special Relativity

__Electrodynamics__[]

- Griffiths - Introduction to Electrodynamics
^{[Errata]}(The standard at most universities) - Wangsness - Electromagnetic Fields (an alternative to Griffiths and a good transition to Jackson)
- Shadowitz - The Electromagnetic Field (Dover Books on Physics) (A cheap alternative and/or supplement to Griffiths, it does electricity and magnetism side by side rather than segregating them)
- Schwartz - Principles of Electrodynamics (Dover Books on Physics) (Another cheap supplement to Griffiths, it's a tad more advanced and mathematical and with an emphasis on SR.)

For more on applications when you're done, see EEE's Electromagnetics recommendations.

__Thermal Physics__[]

The books on Thermal Physics aren't as great as you would hope they be. If you have the time, try to work through an Engineering Thermodynamics textbook to build up your familiarity with the subject matter before attempting to dive into the theory.

- Schroeder - An Introduction to Thermal Physics
^{[Site]} - Kittel and Kroemer - Thermal Physics
- Reif - Fundamentals of Statistical and Thermal Physics

A short and insightful supplement or second pass on thermodynamics is Pippard's "Elements of Classical Thermodynamics". For deeper historical and conceptual understanding, check out some the writings of the creators of the subject like Maxwell, Botzmann, Ehrenfest, and Planck on the History page.

__Quantum Mechanics__[]

- Griffiths - Introduction to Quantum Mechanics
^{[Errata]}(better for students with little exposure to QM) - Townsend - A Modern Approach to Quantum Mechanics (undergrad version of Sakurai)
- Shankar - Principles of Quantum Mechanics (better for students with stronger preparation)

Additionally, the following books take a more conceptual and foundational approach rather than problem solving focus the above have.

- Schumacher and Westmoreland - Quantum Processes, Systems, and Information
- David Bohm - Quantum Theory (Dover Books on Physics) (Sadly no Bohmian Mechanics, does a great job linking the development of quantum mechanics from classical mechanics)
- Peres - Quantum Theory: Concepts and Methods

And for philosophy of QM (by physicists who know what the fuck they're talking about):

- Bell - Speakable and Unspeakable in Quantum Mechanics: Collected Papers on Quantum Philosophy
- Max Jammer - The Philosophy of Quantum Mechanics: The Interpretations of Quantum Mechanics in Historical Perspective

Unfortunately this is pretty much the only good book on Optics at this level, the standard books at most universities are Hecht's "Optics" and Pedrotti, Pedrotti & Pedrotti's "Introduction to Optics", both of these books are severely flawed and would be impossible to use for self-study.
