John Dalton
John Dalton came to the conclusion of atomic theory. He first came across the theory while working with atmospheric pressures. While working with different gasses he came to the conclusion that it was individual particles that had pressured applied to it by gas. This theory was soon known as Dalton’s Law of partial pressure. -
Marie Curie
Marie Curie worked alongside her husband Pierre Curie. They were both devoted scientist and dedicated to working with radio activity. Marie Curie discovered that radio waves were always constant and the never stopped. Her and her husband also the discovered 2 different types of radio active elements one being polonium and the other radium. The pair won a nobel prize for this in 1902. -
J.J. Thomson
Joseph John Thomson was first renowned for his work on the motion of vortex rings contributed to science in 1884. Later on he soon discovered how to separate different kinds of atoms by exposing them to positive rays. -
Ernst Rutherford
Ernst Rutherford’s contribution the science was so great he was named the “Father of the nuclear age”. He was named this because of his discovery of ‘alpha’ and ‘beta’ uranium using foil. One type of radiation is easily absorbed by the foil and the other type of radiation penetrated the same foil. Through more experimenting he discovered that the mass of an atom is in nucleus this lead to the invention of the nuclear model the the atomic bomb. -
Niels Bohr
Niels Bohr contributed many theories to the science world but his most outstanding one was the theory that atoms give off electromagnetic radiation. This theory would soon be a basic understanding of all physicians. Through more exploration in this theory he came up with atomic structures which won him the nobel prize in 1922. -
Henry Mosely
Henry Moseley developed the idea of the x-ray to study anatomy of the human body. From there he also figured out the length of the wavelengths that x-rays use. His main contribution to science was helping to make the periodic table more accurate based on finding a closer figure to the exact number of an elements atomic number. He helped make the periodic table more accurate based on the weight of each element. -
Francis Aston
Francis Aston contributed to chemistry by the invention of the mass spectrograph. This is a device that is used separate particles that are electrically charged using their masses. Using his invention he discovered 212 naturally occurring isotopes. For this discovery in the world of chemistry he won the noble prize in 1921. -
Erwin Schrodinger
Erwin Schrödinger made a big contributing making his own wave equation. He wrote a revolutionary paper on equation stating that electrons in an atom would move as a wave not in particle leaps. Now we know this equation as the “Schrödinger wave equation”. This is now an important aspect of quantum theory. -
James Chadwick
James Chadwick had one of the biggest discoveries in the physics world for his finding of the neutron. He found this by studying Joliot-Curies work to find that if beryllium is exposed to alpha particles it becomes radio active. For this he was awarded the nobel prize in 1935. -
Murray Gell-Mann
Murray Gell-Mann’s biggest contribution to science was the quark system. This system helped classify particles and gave the basic structure of matter. He also developed the strangeness theory that explained meson decay patterns.
