Famous Physicist Facts

His first life accomplishment was about a book. At age twenty-seven, he released a five hundred page textbook called Organic Chemistry. The book won Demidov prize and put him in front of Russian chemical education. In 1867, at age thirty three, he was awarded Chair of General Chemistry. Everybody admired that he changed a difficult branch of chemistry into a logical science. His nomination for the 1906 Nobel Prize failed by one vote. In 1876, he was officially named Professor of General Chemistry at the University of St. Perersburg. After resigning in 1890, he was officially named Director of Bureau of Weights where he stayed until his death in 1907. In 1905, the British Royal Society gave him the Copley Medal, its highest honor! Also in 1905, he was elected to the Royal Swedish Academy of Sciences. Mendeleev’s law was soon discovered after those three elements were found. Not surprisingly, he was remembered as a brilliant scholar, an inspiring teacher, and an amazing writer. He next began a book for organic chemistry. His books, Principles of Chemistry, with two volumes, became standard until the early 20th

The radioactive form of an element acts in the same way the nonradioactive form does. When a person ingests iodine it concentrates in the thyroid gland whether it is in a radioactive or nonradioactive

The pioneering work of Becquerel in 1896 (the discovery of uranium), and the Curies (who subsequently discovered radium and polonium and the energy and heat given off by these new elements which they called radioactivity) led to the remarkable work of Ernest Rutherford. He was a physicist, whose experiments showed that some heavier elements spontaneously changed or decayed into lighter elements (unstable 'parent' elements giving off protons and neutrons to form a 'daughter' element) through the process of radioactivity. He discovered that radioactive materials decay at a very predictable rate, and that lead was the final decay product of uranium. Using Rutherford's ideas, Bertram Boltwood pioneered a method of radiometric dating in 1907. He hypothesized that since he knew how long it takes uranium to break down, he could measure the proportions of lead in uranium ores, and use his calculations to date how long those ores had existed,

The goal was to stop war with explosions. This discovery is what changed war. With the help of Albert Einstein and Robert Oppenheimer was discovered that by splitting the atom, they could create their bomb. They feared that Hitler and Germany would

He discovered many helpful uses for atomic energy. He created the world’s first nuclear submarine named the USS Nautilus. All his work helped to expand the American nuclear fleet that included fifty three submarines and surface ships.

Two miles underground in the Vale Creighton mine lies an advance lab far from the common world. In this lab many experiments are done from sub-atomic and astro-particle physics to the reactions of fruit flies to this underground environment. But one of the experiments is how organisms react to the absence of radiation underground and how it effects life. SnoLab the company in charge of this facility calls this experiment REPAIR (Researching the Effects of the Presence and Absence of Ionizing Radiation).

On August 2, 1939, Einstein proposed an interesting to President Franklin D. Roosevelt. This idea, called the atomic bomb, would change the lives of everyone. Making it was easier said than done, though. They needed a team of scientists: Robert Oppenheimer, David Bohm, Leo Szilard, Eugene Wigner, Felix Bloch, Otto Prisch, Rudolf Peierls, Niels Bohr, Emilio Segre, James Franck, Enrico Fermi, Klaus Fuchs, and Edward Teller. Then they had to find U-235, which looked exactly like U-238, a useless material. The process was hard, especially since only mechanical methods worked. Finally, after an extraction system, a magnetic separation, and a gas centrifuge, all that was needed to be done was to test the entire concept in the deserts of Jornada del Muerto (about money).

A half life lab was conducted by rolling pennies in a cup, and then setting aside those which were heads down. This process represents a half-life of the atom, or the time required for half of a substance sample to decay. The purpose of performing this lab was to simulate the transformation of a radioisotope over time, and to graph the data in a way that relates it to radioactive decay and half-lives. The presumed result of this experiment was that a little less than half the pennies would be face down due to some inconsistencies when shaking and pouring the pennies out of the cup.

It was first developed in the 1940s, and during the Second World War to 1945 research initially focussed on producing bombs which released great energy from the atoms of particular isotopes of either uranium or plutonium.

Ernest Rutherford was a New Zealand born British physicist who is famously known for “splitting the atom.” His work on the gold foil experiment contributed greatly to the model of the atom and helped develop the standard model of the atom to what we now use today. Without his contributions we would still be using the Plum Pudding model, an out dated and incorrect model, and we would have less of an understanding of how atoms form the world around us.

His discovery to radioactivity helped a lot of other scientists. If Henri hadn't discovered it Ernest Rutherford

Marie Curie LIFE OF MARIE CURIE      Marie Curie(1867-1934) was a French physicist with many accomplishments in both physics and chemistry. Marie and her husband Pierre, who was also a French physicist, are both famous for their work in radioactivity.      Marie Curie, originally named Marja Sklodowska, was born in Warsaw, Poland on Nov.7, 1867. Her first learning of physics came from her father who taught it in high school. Marie's father must have taught his daughter well because in 1891, she went to Paris(where she changed her original name) and enrolled in the Sorbonne.

Albert Einstein is considered the most influential physicist of the 20th century. He is known for developing the theories of relativity. He is also noted for his mathematical formula of E = mc² (David Bodanis). Although he was not directly involved in the Manhattan Project, which was responsible for creating the atomic bomb, but he is still considered the mastermind because of his breakthrough formula. In 1921, he won the Nobel Prize for physics for his explanation of the photoelectric effect (A. Calaprice & T. Lipscombe).

This is what led Curie to take Becquerel’s work a few steps further and conduct her own experiments on uranium rays. She discovered that the rays were constant no matter what form or condition of the uranium. She theorized the rays came from the atomic structure. This idea was revolutionary and created its own field in science, known as the atomic physics, this is when Marie coined the word “radioactivity” to describe the phenomena. Even when they had their first daughter Irene in 1897 there work did not slow. Pierre then stopped his own studies to help Marie with her new discovery of radioactivity. In 1898 they discovered a new radioactive element. They named it polonium after Marie’s native country, Poland. They detected the presence of another radioactive element and called this radium. In 1902 they had extracted pure radium to prove its existence as a unique chemical element.

Nuclear knowledge has existed for a long time. Nuclear Engineering U.S. Department of Energy relates, ―By 1900, the physicists knew the atom contains large quantities of energy‖ (par 11). Many others formed good theories, such as Ernest Rutherford and Einstein’s contribution with his equation E=mc^2. In 1934
