-
He burnt phosphorus and sulfur, and proved that the products had the same mass. Thus he established the Law of Conservation of Mass.
-
iDsproved Berthollet with the law of definite proportions, which is sometimes also known as Prousts Law.
-
He discovered that when a beam of light is seperated into two beams and then reunited, it created a pattern of light and dark.
-
the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space. This principle officially came to be known as Dalton's Law of Partial Pressures n 1803. Dalton also introduced the belief that atoms of different elements could be distinguished by their atomic weights.
-
He developed the Quantum theory. He tried to make conclusions from the heat radiation to the radiating atom. The discovery of quanta changed the idea of physics, because it showed that ideas about the nature of radiation and energy were wrong. The Nobel Prize in Physics 1918 was awarded to Max Planck "in recognition of the services he rendered to the advancement of Physics by his discovery of energy quanta".
-
Discovered the photoelectric effect.In the photoelectric effect, electrons are emitted from matter in short wavelenghtd. These are called photoelectrons.
-
Ernest Marsden worked on the structure of the atom. Marsden did this by observing that a tiny fraction of alpha particles fired at a thin gold foil were deflected straight back.
-
he discovered electron and how much they weighed using the CRT. He Nobel Prize of physics for it in 1906.
-
Isolated a new element that came to be called “radium.” They won a Nobel Prize in Chemistry in 1903.
-
Mathematically proved the existence of atoms.Einstein also in 1905 proposed that light energy can be absorbed or emitted only in discrete packets called quantaand this led to Einstein’s winning of the Nobel Prize. Einstein in 1905 also explained the equivalency of mass and energy (e=mc^2)
-
Developed an electrical device to click when hit with alpha particles.
-
He presented the atomic model with a dense neucleous and outside electrons.
-
he completed his theory of atomic structure. This atomic theory was a combination of Rutherford’s work and ideas of the atom, with Planck’s Quantum Theory. He also made a simple ( though innacurate) model of hydrogen. Won the Nobel Prize inChemistry in 1922
-
To his discovery of the increase of wavelength of X-rays due to scattering of the incident radiation by free electrons, which implies that the scattered quanta have less energy than the quanta of the original beam. This effect is now known as the Compton effect,
-
French quantum physicist Louis de Broglie introduced his theory of particle-wave duality. He won the Nobel for Physics in !929.
-
Mostly known for his Pauli Exclusion Principle which states that no two electrons in an atom can have the same four quantum numbers. This allows scientist to give electrons an address to further distinguish themselves from others in the same atom. Won the Nobel Prize in 1945.
-
He developed a way to both mathematicall and visually display wave patterns in electrons. Surpassed Bohr's model.
-
The Uncertainty Principle states the more precisely the position of a particle is determined, the less precisely the momentum is known in this instant, and vice versa. Won the Nobel Prize for Physics in 1932
-
He created a relativistic equation of motion for the wave function of the electron. He shared the 1933 Nobel Prize in Physics for 1933 with Erwin Schrödinger
-
proofs the existence of the neutron which accelerated the research in nuclear physics inmensely. He won the Nobel Prize in 1935 for physics.
-
Took a picture that clearly displayed a positron crossing a lead plate placed in the cloud chamber. Won a Nobel Prize in 1936.
-
He discovered that a newly-discovered neutron decaying to a proton emits an electron and a particle which he called a neutrino. Enrico Fermi received the Nobel Prize in 1938 for "his discovery of new radioactive elements produced by neutron irradiation.
-
researched the action of neutrons. Won the nobel prize in 1935
-
Works on discovering nuclear fission with his aunt.
-
produced Uranium nuclear fission. Otto Hahn won a Nobel Prize in 1944.
-
They developed the theory called quantum electrodynamics.
-
theorized that the differences between protons, neutrons, and newly discovered particles could be explained by the existence of these still smaller particles. The Nobel Prize in Physics 1965 was awarded jointly to Julian Schwinger and Richard P. Feynman "for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles".
