John Dalton
He was in engilsh chemist, meterorologist and physicist. He was best known for his pioneering work in the development of modern atomic theory and his research into color blindness. In 1803 he proposed an atomic theory with spherical solid atoms bassed upon measurable properties of mass. -
World War I
J.J. Thomson began his discovery of electrons and ended with the findings of Buhr's threory. This coincided with the beginning of World War I. The war kept scientists occupied instead of developing new discoveries. -
J.J. Thomson
He was British physicist and nobel lauerate. He was credited for the discovery of the electron and isotops and he was credited for the invention of the mass spectrometer. In 1906 he was awarded the nobel prize in physics for the discovery of the electron. -
The Cold War
After World War II and the United States released the atomic bomb the relationship with other countries was not good. The deployment of the bomb helped lead to the Cold War between the United States and the Soviet Union. -
World War II Atomic Bomb
In 1938 researchers found that bombarding the nucleus of a uranium atom with a neutron made the nucleus to split into two parts and release energy. This was called nuclear fission. The discovery came a few months before the start of World War II in 1939, and fission was used in atomic bombs that helped end the war in 1945. -
Ernest Rutherford
He was a New Zealand chemist and physicist who became the father of nuclear physics. -
Schrodinger
He was an Austrain theoretical physicist, who achivevd fame for his contributions to the quantum mechanics , and especially for the Schrodinger equation, for which he received the nobel prixe in 1933. -
Neils Bohr
He was a Danish physicist who made fundamental contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922. -
Chadwick
He was an English nobel lauerate in phyisics and he was awarded for his discovery of the neutron in 1935. -
Democritus
He was an Ancient Greek philosopher, who is best known for expanding the atomic theory. He maintained the impossibility of dividing things ad infinitum.
