Mathematical Derivation for the Vol. III of Feynman Lectures on Physics: Line by line accurate quantum mechanics mathematical derivation to accompany the … of Feynman Lectures on Physics 4)

Ever become frustrated when the textbook skip and jump steps in formulas derivation in the teaching of important assumption and approximation? If you are like countless students being stuck at, a particular mathematical calculus-working step or steps while reading a simple undergraduate physics text, then this manuscript may help out in your journey.

For the completeness to accompany the undergraduate introduction text of Feynman’s Lectures on Physics, Volume III on Quantum Mechanics study, this text provides a detail line-by-line symbolical derivation workouts that are omitted or incomplete in between every physics definitions. All the mathematical derivations and expansions involve the trigonometry functions and identities, first and second order time dependent and time independent partial differential equations, calculus as well as simultaneous equations solving via matrix or direct substitution method. Readers with/without fundamental handle on Quantum Mechanics and/or undergraduate level mathematics proficiency but wish to study the physics and/or the applied mathematics, can now use this text as a step-by-step systematical fill-in-the-blank reference and derivation counter-checking resource. Readers can follow and learn the essence of Quantum Mechanics from a non-traditional presentation by the late Prof. Richard Feynman.

There are 20 chapters of undergraduate Quantum Mechanical theories examined and derived accordingly as discussed inside the Feynman’s Volume III text. They include, The Quantum Behavior, Identical Particles, Spin One Particle, Spin One-half Particle, The Dependence Of Amplitude On Time, The Hamiltonian, Ammonia maser, Other Two-state Systems, The Hyperfine Splitting In Hydrogen, Propagation In A Crystal Lattice, Semiconductor, The Independent Particle Approximation, The Dependence Of Amplitude On Position, Symmetry And Conservation Laws, Angular Momentum, The Hydrogen Atom And The Periodic Table, Operators, and last but not the least the Schrödinger Equation In A Classical Context.
