Effect On Physics
Configurations of classical charged particles orbiting one another are unstable due to losses of energy by electromagnetic radiation. Even without those losses, Earnshaw’s theorem means that dynamic systems of charges are unstable over long periods. For quite some time, this led to the puzzling question of why matter stays together as much evidence was found that matter was held together electromagnetically.
These questions eventually pointed the way to quantum mechanical explanations of the structure of the atom, and it turns out that the Pauli exclusion principle and the existence of discrete electron orbitals is responsible for making bulk matter rigid.

Famous quotes containing the words effect on, effect and/or physics:
“Living more lives than one, knowing people of all classes, all shades of opinion, monarchists, republicans, socialists, anarchists, has had a salutary effect on my mind. If every year of my life, every month of the year, I had lived with reformers and crusaders I should be, by this time, a fanatic. As it is I have had such varied things to do, I have had so many different contacts that I am not even very much of a crank.”
—Rheta Childe Dorr (1866–1948)
“To get time for civic work, for exercise, for neighborhood projects, reading or meditation, or just plain time to themselves, mothers need to hold out against the fairly recent but surprisingly entrenched myth that “good mothers” are constantly with their children. They will have to speak out at last about the demoralizing effect of spending day after day with small children, no matter how much they love them.”
—Wendy Coppedge Sanford. Ourselves and Our Children, by Boston Women’s Health Book Collective, introduction (1978)
“The fundamental laws of physics do not describe true facts about reality. Rendered as descriptions of facts, they are false; amended to be true, they lose their explanatory force.”
—Nancy Cartwright (b. 1945)
