Planck found a way to avoid this problem. He cut up the radiation, mathematically, into chunks, or quanta. At a particular frequencyf, each quantum of radiation has an energyE, given by the equationE=hf, where h is a constant in nature, now known asPlanck's constant. Let's see how ...
Niels Bohr developed the theoretical model of the atom that most of us are familiar with. This model has electrons orbiting around the nucleus like planets orbiting around the Sun. He also promoted the Copenhagen interpretation of quantum mechanics. Louis de Broglie proposed that all material partic...
Albert Einstein, whose theories on space time and matter helped unravel(解开) the secrets of the atom and of the universe, was chosen as "Person of the Century" by Time Magazine on Sunday. A man whose very name is synonymous with scientific genius, Einstein has come to represent more than...
C. Bradford stated: “The great objection to Langmuir’s theory of atomic structure is the difficulty of accepting his hypothesis of stationary eletrons.” The cases cited are all discussed in G. N. Lewis’s paper, “The Atom and the Molecule” (Journ. Amer. Chem. Soc, xxxviii., p....

Pluralism of TheoriesDear All! I know that the mainstream in Physics supports a mono culture of physical theories only, the mono culture of energetic considerations. This mono culture is described with three fundamental principles: The weak equivalence principle, that means the equality of the ...
and rebirth recycling. As for whether you would do the same thing again, I could not possibly say. As the Universe is imperfect, all it takes is one atom to be out of place, and things could cause a different future on the bounce back out. Your atoms might not end up on Earth next...
