Hace 3 días · La vida y obra de Sir Joseph John Thomson, más conocido como J.J. Thomson, abarca una vasta gama de contribuciones a la ciencia y la educación que continúan resonando en el tejido de la sociedad moderna. Aunque su descubrimiento del electrón es indudablemente su logro más famoso, ...
Hace 3 días · In 1897, the British physicist J. J. Thomson, with his colleagues John S. Townsend and H. A. Wilson, performed experiments indicating that cathode rays really were unique particles, rather than waves, atoms or molecules as was believed earlier.
Hace 5 días · The trolley problem, as it came to be known, was first identified as such by the American philosopher Judith Jarvis Thomson, whose essay “Killing, Letting Die, and the Trolley Problem” (1976) spawned a vast academic literature on the topic.

Hace 5 días · J.J. Thomson's model proposed the "plum pudding" model, where electrons were embedded in a positively charged sphere. The current model of the atom, based on Niels Bohr's work, describes...
28 de may. de 2024 · JJ Thomson and Ernst Rutherford proved that the atom is divisible by their discovery of the electron and the nucleus. So, how did Rutherford discover the nucleus? By alpha scattering experiment, popularly known as the gold foil experiment.
Hace 2 días · Thomson — Discovery of electrons Determined the charge to mass ratio of electrons (e/m = -1.76 x 108C/g) by measuring the deflection of cathode rays in the presence of electric and magnetic fields Robert Millikan —Oil drop experiment Determined charge of electron (-1.602 x 10-19C) and mass of electron (9.10 x 10 -28g) Nuclear Model Ernest ...
