|Kirill Tolpygo electromagnetism
Kirill Tolpygo developed a quantum-mechanical theory of optical and elastic properties of crystals. Crystals in a lattice deform under stress. Kirill Tolpygo predicted when they bend nonuniformly then they generate an electric field.
Shells of ions in a dielectric crystal lattice can bend. Ionic crystals, homopolar crystals, cryocrystals, molecular crystals. Deformations can introduce Coulomb interactions.
A long rubber band powers my balsa glider. I wind it until the band knots front to back. Released, the glider soars through invisible air. I am released from earth like a bird. Its balsa, plastic propeller, and metal hooks maintain static integrity until they hit the barn. Everything’s dynamic, bending in space and time, undergoing stresses while electrons are careening.
