Experiments with Vibrating Plates,oblem. She had to build especial plates to carry out her own experiments. Her memoir of 1825 begins with a review of the relevant literature, citing papers by Euler, Bernoulli, Lagrange, Chladni, Poisson, Navier, Savart, and Italian physicist Giordano Riccati.剥皮 发表于 2025-3-29 12:11:16
Elasticity Theory After Germain,e first fourth-order partial differential equation now known as the Germain-Lagrange equation. Much more work had yet to be done, of course. The governing equation for the equilibrium of thin elastic plates was derived from that basic formulation.chronology 发表于 2025-3-29 19:08:48
,Germain and Fermat’s Last Theorem, (last) theorem of Fermat as the topic for the 1818 contest of mathematics. A happy coincidence? Germain kept her feelings secret, or at least there are no written words to shed light on her intellectual delight, as the new competition would carry her back to her first love—number theory.
