From this work follows one of the most fundamental principles of physics, the conservation of mass. " Also, he found that water was made up of hydrogen and oxygen.

His theory was much more advanced and elaborate than the previous wave light theory. This year he also discovered that the cause of an astigmatism is a misshapened eye cone.

-
Wrote in his books that to "calculate atomic weights from percentage compositions of compounds, using an arbitrary system to determine the likely atomic structure of each compound. If there are two elements that can combine, their combinations will occur in a set sequence."
-
His theory was that atoms were made up of smalle particles, hence the elctron. To prove his theory he he used a cathode ray tube and saw that the little glowing particles were the same, thus he named them electrons.
-
Max Planck discovered the "explanation of the energy attributed to the light is explained by subsequent theories of which the Max Planck quantum theory is one important theory." Finally created a correct way to measure light and other thing.

During this time they discovered that some atoms are much more radioactive than others which led to furhter studies.
-
Them and another scientist, won a nobel prize in physics for their work in the radioactivity of atoms.

This established the law of mass- energy equvalance, e=mc^2. This became the foundation of the development of atomic energy.
-
He proposed a measure for the relative rate of decay uranium atoms that would accurately date minerals. He also discovered several different elements.
-
He won this because of his theoretical experiments on the conduction of electricity by gases.
-
He won the Nobel Prize in Chemistry "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances".
-
With the help of his peers he helped discover the atomic theory and the theory of the atomic structure of an atom. They found that atoms have a small, dense, positively charge nucleus.
-
She recieved her second nobel prize in Physics because of her discovery of the discovery of polonium and radium atoms. She was the first women to get this award.
-
Was a redone version of Rutherfords model. He concluded that electrons orbit around the nucleus without loosing energy and electrons with low energy orbit closer to the nucleas.
-
"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'".
-
Shwowed that when a quanta of light energy stikes metal atoms, the quanta forces the atoms to releace electrons
-
"The Nobel Prize in Physics 1921 was awarded to Albert Einstein 'for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect'".
-
In 1922 Niels Bohr was awarded the nobel prize of physics "for his services in the investigation of the structure of atoms and of the radiation emanating from them".
-
He discovered the Compton effect which explains the when wave lenghts and x rays collide, their electrons are altered.
-
Disproved the theory of that time and proved "that particles can behave like waves, and waves (radiation) can behave like particles."
-
Set forth the matrix formulation of quantum mechanics.
-
"The principle states that no two identitcal fermions may occupy the same quantum state simultaneously"
-
He "used mathematical equations to describe the likelihood of finding an electron in a certain position. This is known as the quantum mechanical model of the atom. Unlike the Bohr model, the quantum mechanical model does not define the exact path of an electron, instead, it predicts the odds of the location of the electron." (abcte.org)
-
In 1927, he won the Nobel Prize in Physics for his wirk in the Compton effect.
-
A much more portable machine that would count alpha particles
-
These excepts of his writing gave hinted toward the idea of a particle with the same mass and charge as the known negative electron. This positron was later founded by Carl Anderson.
-
the dirac equation described the behavior fermions, and predicted the existance of antmatter.
-
He won the Nobel Prize of Physics in 1929, for his work in discovering hte nature of waves in electrons.
-
After preforming a expriment on cosmic rays,“carrying a positive charge but having a mass of the same order of magnitude as that normally possessed by a free negative electron."
-
While working with Rutherford to research the attom's nucleus. They discovered a particle that has no charge and named it the neutron.
-
He won the Nobel Prise in Physics for his work and creation of quantum mechanics and the creation of allotropic forms of hydrogen.
-
In 1933, Paul Dirac and friend Erwin Schrödinger won the nobel prize for their work in finding new and productive forms of atomic theory.
-
For his efforts and discovery of new productive forms of atomic theory.
-
Demonstrated that nuclear transformation occurs in every element subject to neutron bombardment. Resulthed in the discovery of slow neutrons
-
She was known for her synthesizing of radioactive elememts. They successfully transformed boron into radioactive nitrogen.
-
In 1935, James Chadwick was awarded the Nobel Prize for physics for his work in discovering the neutron.
-
She was awarded a Nobel Prize in Chemistry for her work in synthesizing radioactive elements.
-
He rescieved a Nobel Prize fin Physics for his work in discovering the positron/positive electron.
-
Him and other scientist worked together and worked with the nuclear fission of atoms such as uranium to create nuclear power and weapons.
-
"The Nobel Prize in Physics 1938 was awarded to Enrico Fermi 'for his demonstrations of the existence of new radioactive elements produced by neutron irradiation, and for his related discovery of nuclear reactions brought about by slow neutrons'".
-
In their research they found that when uranium is bombarded with neutrons it splits and then split with other uranium atoms causeing a very powerful bomb.
-
After the discovery of a neutron and a uranium nucleus collision formed barium as a byproduct. Frisch "explained the process in terms of excessive electrical charge, estimated the energy released and coined the term "fission" to describe it.d that".
-
He recieved his award for his work in the discovery of the fission of heavy nuclei.
-
He recieved a nobel prize for his work in discovering the exclusion principle/ Pauli's principle
-
"1964 Murray Gell-Mann and George Zweig tentatively put forth the idea of quarks. They suggested that mesons and baryons are composites of three quarks or antiquarks, called up, down, or strange (u, d, s) with spin 0.5 and electric charges 2/3, -1/3, -1/3, respectively (it turns out that this theory is not completely accurate). " Later discoveries allow us to think of quarks as physical objects, but cannot be isolate.
-
discovered that the reaction of an electrons field alters the properties of a particle including the mass.
-
"The Nobel Prize in Physics 1965 was awarded jointly to Sin-Itiro Tomonaga, Julian Schwinger and Richard P. Feynman 'for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles'".
