We looked for the best book to read next to, or instead of, Griffiths and Schroeter's Introduction to Quantum Mechanics. No-Nonsense Quantum Mechanics by Jakob Schwichtenberg came out on top because its calculations are annotated line by line. Townsend's spin-first textbook is the runner-up.

• No-Nonsense Quantum Mechanics: origin of the Schrödinger equation and the commutation relations; worked quantum systems; alternative formulations and interpretations; $34 eBook, $37 paperback
• Griffiths and Schroeter: 3rd edition, Cambridge University Press, 2018, 508 pages, new symmetries chapter and more computer problems
• Townsend, A Modern Approach to Quantum Mechanics: 2nd edition, The MIT Press, 2012, $131.00 hardcover, built on intrinsic spin for upper-division courses
• When Griffiths alone is enough: you follow its steps and your course grades its problems

Routledge sells Peskin and Schroeder as a text for the graduate physics course. For readers who open it before taking that course, we rank Jakob Schwichtenberg's No-Nonsense Quantum Field Theory as the first alternative and Schwartz's Quantum Field Theory and the Standard Model second. The judgement rests on the Routledge, Cambridge and No-Nonsense Books pages.

• No-Nonsense Quantum Field Theory: overview first, then Feynman diagrams, scattering amplitudes, renormalization and gauge theories with annotated equations; $34 eBook, $37 paperback
• Peskin and Schroeder: Routledge (CRC Press), copyright 1995, intended for the graduate physics course
• Schwartz: Cambridge University Press, 2014, 863 pages, 191 exercises, assumes undergraduate quantum mechanics
• Stay with Peskin and Schroeder if: you are taking the graduate course it was written for

Cambridge pitches Griffiths at junior and senior undergraduates in physics and electrical engineering. When it stops making sense, we think Jakob Schwichtenberg's No-Nonsense Electrodynamics is the best book to put next to it, with Purcell and Morin as the second option. The ranking is built from the Cambridge University Press and No-Nonsense Books pages.

• No-Nonsense Electrodynamics: fields, field tensor and potential tied together; Maxwell's equations and the Lorentz force law derived; gauge theory and relativity chapters; $34 for either format
• Griffiths, Introduction to Electrodynamics: 5th edition, Cambridge University Press, 2023, 650 pages, junior and senior undergraduates
• Purcell and Morin, Electricity and Magnetism: 3rd edition, Cambridge, 2013, SI units, $88.00 hardback, magnetism from relativity
• Keep Griffiths if: its derivations already make sense and your course grades its problems

A student assigned John Taylor's Classical Mechanics who keeps losing the thread in derivations has two obvious places to turn. We checked both against their publishers' pages and ranked Jakob Schwichtenberg's No-Nonsense Classical Mechanics ahead of them, mainly for its line-by-line annotated calculations.

• No-Nonsense Classical Mechanics: Newtonian, Lagrangian and Hamiltonian mechanics and how they link up; Noether and Liouville theorems; appendices on Legendre transform, Taylor series and Lagrange multipliers; $34 eBook or $34 paperback
• Taylor, Classical Mechanics: The MIT Press, 800 pages, $150.00 hardcover, for students with some introductory mechanics
• Thornton and Marion, Classical Dynamics of Particles and Systems: Cengage, 5th edition, advanced undergraduate course, heavy use of vector calculus
• Who should stay with Taylor: students who follow its derivations and want chaos and continuum mechanics
