J.J. Thomson
J.J. Thomson

Joseph John Thomson was born in Manchester, England in 1856. Thomson was indeed a good scientist, but he did not know that at first. He attended college at a time when science was finally getting recognized as an important subject (Morgan). Thomson's road to becoming a scientist was not paved for him from the start, as his father had other plans for him. Joseph was intended to become an engineer, but when the time came to pay for his studies, his family could not make ends meet. Instead, Thomson attended Owens College in Manchester. The wonderful science professors at Owens College recognized Thomson's niche for science and recommended that he attend Trinity College located in Cambridge (J.J. Thomson). There, Thomson became a mathematical physicist, and in 1884 he was offered the position of Cavendish Professorship of Experimental Physics at Cambridge. He was twenty-eight years old when he accepted this position, and people were very surprised because he was young, and was considered a trained mathematician, not a scientist (Morgan). However, it seems that Joseph John Thomson proved all of his doubters wrong. The first experiment Thomson conducted focused on the resistance of metal wires affects on temperature, which lead to even more important research on methods of measuring extremely high temperatures. Finally he settled on one field, the discharge of electricity through gases at low pressures, in which most of his best work was done (Morgan). Thomson's studies on electro-magnetic radiation and discharge through gases are the most closely related characteristics of physics taught today in schools and universities all over the world. In 1897 Thomson discovered the electron, his most notable achievement. At the time of his discovery many other scientists were working on the same thing (Joseph John Thomson). He was doing a lot of research on the nature of electric discharge in a high-vacuum cathode-ray tube. The ray’s deflection by electrically

    Werner Heisenberg worked right around the time of James Chadwick. He discovered that neutrons, electrons and protons do not have a direct connection. His discoveries introduced atomic physics. He found out that the number of neutrons are not always the same. One thing led to another and the discoveries of Heisenberg helped to create the nuclear bomb.…

    Introduction: According to the Bohr atomic model, electrons orbit the nucleus in fixed paths with specific energies. Each path is therefore often referred to as an “energy level”. Electrons possessing the lowest energy are found in the levels closest to the nucleus. Electrons of higher energy are located in progressively more distant energy levels.…

    Although Joseph John (J.J.) Thomson (1856 - 1940) was mainly a physicist, his discoveries are closely connected to the chemical community. Thomson used Crookes high vacuum cathode ray tube in his discovery of electrons. He found the green beam produced by the cathode ray tube was a completely negatively charged material. Experimenting with different electrically charged plates and magnets in the cathode ray tube and observing the deflection of the rays he had enough evidence to say that particles smaller than atoms existed. By doing this experiment multiple times he compiled enough data to conclude that the mass of one of these particles, which he called an electron, was lighter than an atom of hydrogen by around 2,000 times. He also found the ratio of charge to mass (e/m) would be the same for any electron.…

    The story about Nikola Tesla is the story of a genius who was largely disrespected and abused by other scientists and inventors. Through my research I have managed to find out about the forgotten genius, his creation, the competition against direct current, and his true predictions. Furthermore, I talk about why this unfortunate futurist did not receive the prestige for his work; yet, considered the best scientist of all times.…

    Benjamin Thompson was born in 1753 and he was a leading figure in the history of thermodynamics. He denied the current belief that heat was a liquid form of matter, instead proposing that it was a type of motion. He made this theory while watching the manufacturing of cannon barrels. The process involved a drill that bored into a solid block of metal. So much heat…

    was Klaus Fuchs. Klaus Fuchs was responsible for providing the Soviet Union with crucial information about the Manhattan project and the development of the atom bomb, the importance and value of the information that he gave the Russians is unfathomable. “By handing over the secret of the plutonium bomb and implosion to the Soviets, Fuchs allowed the Soviet bomb project to skip the length and astounding expensive development stage that had led the Manhattan project to that solution.” Fuchs alone sped the Soviet Union’s atomic bomb program up by months allowing them to skip months of expensive, tedious, and resource consuming work.…

    August 9th,1945 the second atomic bomb named “Fat Man” was dropped on Nagasaki, Japan. In the image noted at the end of the paper, it shows Fat Man just after it has dropped. The Manhattan Project is considered to be an important factor in ending World War 2 II. The photo is a candid depicting the damage that will come. The Manhattan Project started in 1939, with Leo Szilard, a Hungarian physicist that drafted a letter and then sent it to Franklin D. Roosevelt and it was signed by former teacher Albert Einstein. Lead scientist of the project was Robert J. Oppenheimer, and was one of many that were considered father of the atomic bomb. Many other famous scientists were involved in the Manhattan Project including Aage and Niels Bohr,Enrico Fermi, Richard Feynman,Frank Oppenheimer,Pief Panofsky, Edward Teller,Victor…

    There was a flash of light so powerful it could be called a sun. An explosion so powerful it turned sand into glass. A sound so loud that it was heard 100 miles away. The world’s first atomic bomb had just exploded. The Manhattan Project was the code name for the United States nuclear development project. It was lead by Major General Leslie Groves of the U.S. Army Corps of Engineers and physicist J. Robert Oppenheimer, who was the director of the Los Alamos National Laboratory. The program was hurried along after the United States government saw the importance and possibilities of the atomic bomb.…
