Max Planck
Max Planck discovered the quantum physics/theory. He showed hat light must be emitted and absorbed in discrete amounts if it was to correctly describe observed phenomena. Quantum theory deals with the the particles that atoms are made of. He originated "Quantum Theory". He is known by the "Planck Constant" which is 6.626x10^-34 kg/s -
Einstein
His general theory of relativity lead to further discoveries about the atom. Since he proved that E=mc^2, which means that mass is merely just an incredibly condensed amount of energy, then physicist researched on how to unlock matter into enormous energy, which led to the discovery of the atom bomb shortly after Einstein published General Relativity, by a German scientist Lise Meitner. -
Niels Bohr
Niels Bohr discovered the Bohr model which proves that the atom has a small positively charged nucleus. Electrons surrounds the nucleus and they travel around it in a circular orbit. Instead of gravity, these electrons are charged with electrostatic forces. -
Erwin Schrodinger
Eerwin Schrodinger was famed for his contributions to quantum mechanics, especially the Schrodinger equation. He devised the schrodinger's cat experiment. (Paradox) -
Louis de Broglie
Louis De Brogile is known for a lot of things but he is most known for discovering the process of electron diffraction by crystals. In 1952, he won a Nobel prize in physics for discovering the wave nature of electrons. He also was awarded a gold medal from the French National Scientific Research Centre. -
Werner Heisenberg
Werner Heisenberg was a German theoretical physicist and one of the key creators of quantum mechanics. He proposed his Uncertainty Principle. You cannot know the position and momentum of a moving object simultaneously. -
Photoelectric Effect
In the photoelectric effect, electrons are emitted from solids, liquids or gases when they absorb energy from light. Electrons emitted in this manner may be called photoelectrons. For example – red light cannot release electrons from Na metal even if the light is extremely intense whereas violet light, even if relatively faint, easily releases electrons from violet light. -
Compton Scattering
Compton scattering is an inelastic scattering of a photon by a free charged particle, usually an electron. It results in a decrease in energy of the photon. called the Compton effect. Part of the energy of the photon is transferred to the scattering electron. -
Bohr Model
In 1913 Niels Bohr came to work in the laboratory of Ernest Rutherford. Rutherford, who had a few years earlier, discovered the planetary model of the atom asked Bohr to work on it. The Bohr model of the hydrogen atom. A negatively charged electron, confined to an atomic orbital, orbits a small, positively charged nucleus; a quantum jump between orbits is accompanied by an emitted or absorbed amount of electromagnetic radiation. -
Arthur Compton
Arthur Holly Compton, was foremost a physicist.Compton believed that a photon was special and that it would always travel at the speed of light and therefore it had an associated wavelength and frequency. Compton’s experiments involved an X-ray colliding with an electron. The Compton effect was observed by Arthur Holly Compton in 1923. -
Schrodinger's cat
A cat, a flask of poison, and a radioactive source are placed in a box. If an monitor detects radioactivity, the flask is shattered, releasing the poison. The Copenhagen interpretation of quantum mechanics implies that after a while, the cat is simultaneously alive and dead. Yet, when one looks in the box, one sees the cat either alive or dead, not both alive and dead. This poses the question of when exactly quantum superposition ends and reality collapses into one possibility or the other.
