Sir Issac NewtownBorn in Lincolnshire, England on the 25th of December 1642. He invented the Reflecting telescope, it is a telescope with mirrors that reflect light and form an image. Sir Isaac Newton was a great mathematician but he made a few mistakes One day Isaac darkened his room and put a hole in his blind allowing one beam into his room. The sunlight in his room created colour spectrum. Isaac Newtown was the first person to prove that a white light is every colour we can see.
Sir Isaac NewtownIsaac died in Kensington, England on the 20th of March Isaac was interested in light and colours. Isaac proved the world was oval not round, also the planets revolve around the sun. He proved that gravity is a force that makes things drop instead of floating away.
John DaltonJohn was born on September 6th, 1766, in Cockermouth.
All matter is composed of atoms.
Atoms cannot be made or destroyed.
All atoms of the same element are identical.
Different elements have different types of atoms.
Chemical reactions occur when atoms are rearranged. Compounds are formed from atoms of the constituent elements.
James Clerk Maxwell• James was born on 13, 1831, in Edinburgh.
• He was a Scottish physicist.• He invented the first Coloured photograph.
• His most noticeable achievement was formulating a set of equations and experiments.
John DaltonJohn died on the 27th of July 1844, in Manchester. Dalton discovered that evaporation, and evaporated water exist in the air we breath.
John thought evaporation might be the mixing of water particles with air particles. He did multiple tests on this theory. John made the hypothesis that the sizes of the particles making up different gases, so everyone of them must be different.

James Clerk Maxwell• James Died on November 5, 1879, Cambridge.
• He also did equations of electricity, magnetism, and optics into a theory.
• Maxwell's achievements in electromagnetism have been called the "second great unification in physics", since sir Isaac Newtown’s discoveries.
Niels Bohr• Niels Bohr was born on October 7,1885.
• Neils based his work on the quantum theory – electrons that travel around the atom in a motionless orbit.
Erwin Rudolf Josef Alexander Schrödinger• Erwin was born on the 12 Aug 1887 in Erdberg, Vienna, Austria.
• He achieved fame for his contributions to quantum mechanics.
• This was why he received the Nobel Prize in 1933.
James Chadwick• James was born on the 20th of October 1891, in Bollington.
• The neutron was not discovered until 1932 when James Chadwick used data to calculate the mass of the neutral particle.

• He died in March 19, 1987, Louveciennes.
Enrico Fermi• Enrico was born on September 29, 1901, in Rome.
• He was known for his contributions to the nuclear and particle physics, and statistical mechanics.
• Fermi was awarded the Nobel Prize in Physics for his work on induced radioactivity.
• He went to the University of Pisa from 1918 to 1922 and later at the universities of Leyden and Gottingen.
• He became a professor of theoretical physics at the University of Rome.
Werner Heisenberg• Werner was born in December 5, 1901, Würzburg.
• He attended the University of Munich, in Germany.
Paul Dirac• Paul was born in August 8, 1902, Bristol.
• He was an English mathematician and theoretical physicist.
• His first major contribution t o the atom theory was simple form of quantum mechanics.
Ernest Walton• Ernest Walton was born on the 6 October 1903.
• He split the atom (atomic nucleus). It took place in Cambridge, UK, in the Cavendish Laboratory.
• This was a world famous laboratory run by run by Lord Ernest Rutherford.
Glenn Seaborg• Glenn was born in April on 19, 1912, Ishpeming.
• Glenn went to the University of California at Berkeley.• His best-known work is involved with the isolation and identification of transuranium elements.
• He shared a 1951 Nobel Prize with Edwin Mattison McMillan.
Ernest Rutherford• He died on the 19th of October 1937, in Cambridge.
• Ernest discovered that this model suggested that most of the mass of the atom mostly empty space and had a small nucleolus.
• Rutherford found out that there was 1 in 8000 chance of bouncing back through the atom. His theory was that most of the atom was made up of 'empty space'.
Enrico FermiDied November 28, 1954, in Chicago.
• He received the Nobel Prize for "his discovery of new radioactive elements produced by neutron irradiation, and for the discovery of nuclear reactions brought about by slow neutrons."
• Fermi moved to the University of Chicago to be in charge of the making feasible the of the atomic bomb.
• There is a plaque that reads: On December 2, 1942, man achieved here the first self-sustaining chain reaction, thereby initiated the controlled release of nueclar energy.
Albert Einstein• Albert died on the 18th of April 1955, in Princeton.
• In 1905 he published a number of scientific works, which included the Theory of Relativity, the nature of light and did a crucial test on atoms.
• The outcome of this complex system is what helps science today, it will always be a remarkable discovery.
Erwin Rudolf Josef Alexander Schrödinger• Erwin died on the 4 Jan 1961 in Vienna, Austria.
• After working with his friend Albert Einstein, he proposed the Schrödinger's cat thought experiment.
• He had a thought, “Why not go all the way with particle waves and try to form a model of the atom on that basis?”
• His theory was like a violin string vibrating except that the vibrations traveled in circles.
• The "psi" symbol of Erwin's wave came from the Greek lettering system.
Niels BohrHe died on November 18 1962. His work also lead to the theory of energy levels inside an atom – which is like an electron that drops from a high orbit to the low orbit, if it does this it is lowering the energy levels to get there.
Lise Meitner• Lise Died in October 27, 1968, Cambridge.
• She developed new ways of investigating radioactive decay by recoil methods and the death/decay of many other elements.
• The process was named after Pierre Auger who took Meitner work and proved it.
James Chadwick• James died on July 24, 1974, in Cambridge.
• As of about 1930 it was thought that the fundamental particles were protons and electrons.
• But by this time it was known from the uncertainty principle as the "particle-in-a-box".
Werner Heisenberg• He died in February 1, 1976, Munich.
• He created matrix mechanics and the first version of quantum mechanics in 1925.
• He mainly studied physics.
• Werner soon became interested in plasma physics and atomic physics.
Paul Dirac• Paul died in October 20, 1984, Tallahassee.
• He applied Albert Einstein’s Einstein's special theory of relativity to the quantum mechanics of his own and it showed that the electron must have spinned of ½.
• He shared the 1933 Nobel Prize for Physics with Erwin Schrdinger.
• Dirac retired from Cambridge in 1969 and held a professorship at Florida State University from 1971 he died.
Louis de BroglieHe died on this day
• He said that electrons could behave, as waves under some conditions, and a finding that helped scientists soon understand that the atom didn't behave like the solar system.
• This was because electrons do not move in regular orbits.
Ernest Walton• Ernest Walton died on 25 June 1995.
• He had built the particle accelerator machine so he could split the atom nucleolus.
• He worked closely with John Cockcroft.
• Einstein’s e=mc2 was proven true due to this.

• He served as head of the Atomic Energy Commission.
• He later played a big role in the passage of the Nuclear Non-proliferation Treaty.
• In 1997 his name was given to the new element seaborgium.
• He was the first living person to have had been so honoured.
