He found that the crystals had clouded the plates when they were developed. Becquerel was extremely excited by this discovery. He called the rays “uranic rays” and assumed they came exclusively from the element uranium. The scientist Marie Curie became curious about “uranic rays” and began to research them. She worked with her husband to invent a machine that measured weak electric currents so she could test different rock samples for the rays.
He completed his first degree at the University of New Zealand and began teaching at a school in New Zealand, where he taught unruly pupils. He later got a scholarship to Cambridge University, where he became J.J Thomson’s first graduate student at the newly open Cavendish Laboratory. After that he began to experiment with radio waves and later on went to join Thomson’s investigation of conducting electricity through gases. However, after breakthroughs by Marie Curie and Henri Becquerel in the field of radioactivity he turned his attention to this branch. 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).
Rutherford's Gold Foil Experiment Rutherford started his scientific career with much success in local schools leading to a scholarship to Nelson College. After achieving more academic honors at Nelson College, Rutherford moved on to Cambridge University's Cavendish laboratory. There he was lead by his mentor J.J. Thomson convinced him to study radiation. By 1889 Rutherford was ready to earn a living and sought a job. With Thomson's recommendation McGill University in Montreal accepted him as a professor of chemistry.
He worked hard to earn a doctorate in physics in 19911 which he received from Copenhagen University. The next year, 1912, Bohr was working for Nobel laureate, J.J. Thompson, in England. He was introduced to earnest Rutherford whose discovery of the development of an atomic model and nucleus had given him a Nobel peace prize in chemistry in 1908. Bohr began to study the properties of atoms under Rutherford’s tutelage. Rutherford and Planicks theory needed help with their theory and description so Niels Bohr helped explained what happened inside of the atom and developed a picture of atomic structure.
Niels Bohr Born in Copenhagen, Denmark, on October 7, 1885 to mother Ellen Adler, and father, Christian Bohr, Niels would later go on to be a Nobel Prize winner in the category of physics. He attended the University of Copenhagen, where he studied physics. In 1911 he received his doctorate and left to England to study under J.J. Thomson, the man who discovered the electron. In 1912 he married Margrethe Norlund. Together they had 6 sons, one of which followed in his father’s footsteps and won his own Nobel Prize in physics in 1975 Bohr’s main focus was working on a way to understand the structure of an atom.
Niels Bohr was a major contributor to modern physics. He won a Nobel Prize for his work on the atomic model. Also he came up with a way to furthermore define what a nucleus looks like, and also worked on the Quantum theory. He accomplished all of this while living in Copenhagen, Denmark and being a Jewish Chemist during World War II. Post-war he became a major contributor to his Open-World theory of helping Nations intelligence between each other about weapons of mass destruction.
Ernest Rutherford Ernest Rutherford was born in Spring Grove in New Zealand on August 30th, 1871. His parents, James and Martha, had emigrated from Great Britain and believed their children, numbering 12, should have proper education. At the age of 16 Ernest won his first scholarship to Nelson College, where he was a popular student. He followed with a second scholarship to Canterbury College in Christchurch, and by 1893 had graduated with first class honours in Physics and Mathematics. Rutherford stayed at Canterbury for a further year to study Physics in more detail, particularly how iron reacted in magnetic fields.
In the early 1900s a Japanese scientist named H. Nagaoka designed an atom model as a large sphere surrounded by a ring of negatively charged electrons. Also, during the early 1900s (1898-1907) a physicist named Ernest Rutherford worked on experiments to test current atom models. His experiments involved shooting rays of alpha particles (small positively charged particles) though very thin pieces of gold foil. Based on Thomson's model, Rutherford hypothesized that the alpha particles would travel through the gold foil mostly unaffected by the gold. He was right.
It was during this period that he developed his interest in the subject in which he was later to excel. In 1893, after obtaining his mastership in physics, he was appointed Fellow in Physics at Columbia University. He afterwards received his Ph.D. (1895) for research on the polarization of light emitted by incandescent surfaces - using for this purpose molten gold and silver at the U.S. Mint. On the instigation of his professors, Millikan spent a year (1895-1896) in Germany, at the Universities of Berlin and Göttingen. He returned at the invitation of A.
Eugene Goldstein was a German physicist, who was an early investigator of discharge tubes. Furthermore, he discovered the anode rays and is credited for the discovery of the proton. This investigation led to J.J Thomson’s famous experiment that resulted in the discovery of the Electron. In the 1890’s numerous scientists were continuously studying radiation, the emission and transmission of energy through space in the form of waves. Information gained by conducting these experiments, benefited our understanding of the structure of an atom.
