The bookshelf

A shared companion. Short, focused chapters on the mathematical machinery the other books invoke — calculus, vector calculus, complex exponentials, ODEs, PDEs, Fourier, linear algebra, dimensional analysis. Link in from anywhere, scan, return.

A second shared companion, alongside Math Foundations. Short, focused chapters on the physical machinery — mechanics, kinetic theory, thermodynamics, fluid mechanics, elasticity, surface tension, waves as physical objects. Link in from anywhere, scan, return.

A first-principles tour of the signal — molecules, the wave equation, Fourier — before any ear gets involved. Built to stand on its own and to set the stage for the hearing volume.

The flagship volume. We follow one sound — "Hey Dr. Miles!" — from the pinna into the cochlea, up the auditory pathway, into the cortex, and out the other side as meaning.

The applied volume. We take the math and acoustics from the other books and walk through the clinical tools an audiologist uses: audiometers, tympanometers, OAE probes, evoked-potential systems, hearing aids, cochlear implants, bone-conduction devices, real-ear verification. Each chapter ties one instrument to the physics it probes.

The bubble-physics volume. Picks up from the bridge lesson at the end of the sound book and develops the field on its own terms: nucleation, the Rayleigh–Plesset equation, collapse and microjets, sonoluminescence, the Blake threshold, bubbly and cavitating flows.
