In 1898, Marie Curie (Polish physicist) and Pierre Curie (French physicist) were one of the first scientists to isolate radium and polonium from pitchblende (uraninite). Henri Becquerel received a Nobel Prize for his work, finding radioactivity in uranium. Wilhelm Konrad Rontgen also received a Nobel Prize for discovering the X-ray. These breakthroughs aforementioned were why he turned his attention to radioactivity. His ability to work creatively, not only by himself, but also with other associates, whom most were already established in the field of science.
The Bohr model is a big part of Chemistry history. Neils Bohr proposed this model in 1913. It states that electrons orbit the nucleus at set distances. The model was an expansion on the Rutherford model overcame (Coffey, Universe Today). Neils Bohr’s model was based on his observations of the atomic emissions spectrum of the hydrogen atom (Coffey, Universe Today).
In conclusion, Kepler played a huge role in the Scientific Revolution with his many genius discoveries and major accomplishments due to his early developed love for science. His contributions to science and mathematics played a big role in the development of science. Without his genius it could have taken years longer to discover some of the things he did. Therefore, Johannes Kepler is one of the most important astronomers of the Scientific Revolution.

Across disciplines 1. Albert Einstein is best known on science. For his Special and General Theory of Relativity and the concept of mass-energy equivalence expressed by the famous equation, E = mc2. Not only is he related to science but also math. He is related to math because he contributed several equations to calculus and geometry, ten of which are called the Einstein Field Equations.
One of the next most recognized people involved in the progression of atomic theory was J.J. Thompson. Thompson had researched the work of William Crookes whose research concluded that cathode rays were deflected by magnetic fields. Thompson elaborated on this conclusion and found that cathode rays were also deflected by an electric field. With much experimentation Thompson theorized that although the atom was made up of small particles it was not the same indestructible model proposed by Dalton. A man named Milikin determined the mass of an electron to be 0 amu and the relative charge to be negative 1.
With the gold foil experiment, tested by Ernest Rutherford, he discovered the existence of the positively charged nucleus. He proved this when the experiment was happening, a small fraction of the photons th... ... middle of paper ... ...lieve that there really is a Higgs Boson particle. I know they have not found it yet but there is lots of evidence to prove that there is a Higgs Boson particle. We as a science community have not been using the right experiments to find the particle. There are lots of things that when put together makes proof of the missing Higgs Boson particle.
This work catapulted his career as an experimentalist and captivated the minds of many great physicists. After discovering these particles by using an electrometer to measure electric current created by radiation, Rutherford wished to leave radio-chemistry behind and get back into the physics world; he began by using his latest discovery to learn about atoms and their structures. Before he could do this, he needed to learn more about the behavior and structure of the alpha particles. Ernest and his partner Hans Geiger developed a machine that could aid in the counting of alpha particles called the Geiger Counter. The men applied a voltage to a metal cylinder with a wire running through its center, then allowed particles to pass through a small window where they created gas ions by colliding with gasses.
