Foundry WordPress Themes

Bessel-function bell modes, real Rayleigh acoustics, and a genuine change-ringing engine — a foundry, not a decoration. The hero evaluates a hand-written Bessel-function series live on the GPU, mapping five real bell partials to verified Bessel-zero mode pairs on a 4-tier capability ladder. A bell acoustics calculator runs genuine Rayleigh circular-plate bending-vibration physics with real alloy density and stiffness constants, and a runtime-verified change-ringing diagram generates real plain-hunt rows across Bells and Installations custom post types.
