Richard P. Feynman Early Life Richard was born on May 11th, 1918, in New York City, the first son of Melville and Lucille Feynman. He enjoyed science and mathematics from an early age, most of which he taught himself before it was taught in school. His primary source for self-learning was the Encyclopedia Britannica and a lab that he set up in his room at home. In this lab, he dabbled in electronics, whether it was repairing the radio or just making some circuits. In high school, Feynman was ahead in physics and mathematics, already a master of differential equations, trigonometry, and other high levels of calculus, but he was lacking in his other subjects, such as English and history. Feynman applied to many schools but was turned down either because of his lacking grades in social sciences or because of his Jewish background. However, Massachusetts Institute of Technology readily accepted him, being a top scientific school even then, and he set out to major in mathematics, though he changed his major several times. Feynman was not satisfied with doing mathematics without a specific purpose, and so he eventually ended up in the field of physics, specifically interested in quantum physics. Richard received his BS from MIT in 1939, four years after entering college, and went on to receive his PhD at Princeton. World War II After college, Feynman began to shine in his field. In 1942, he was invited to join the team that developed the atomic bomb in Los Alamos and Princeton. Initially, he declined to help create a weapon of such mass destruction, but he changed his mind when he considered that Hitler would likely have no qualms about making an atom bomb. Richard played a crucial role in developing safe methods to separate various radioactive materials and determining the amount of uranium needed to achieve critical mass without requiring large-scale detonations. Major Contributions to Physics After World War II, and a brief respite from research, Feynman resumed his work on quantum physics. Over the next few decades, he worked on several projects and achieved success in most of them. Along with another physicist, he tested and proved their theory on "weak decay," which explains how it occurs and its results. Feynman's most significant contribution was his diagrams that describe how particles act in a system and express this movement in mathematics.
After being taken by the Germans convinced others that they still had the lead in developing a fission weapon. It all started with the “Hungarian conspiracy” that had everyone convinced that the creation of a nuclear bomb was possible, but that the German government was already doing research in this field of study on such a weapon. To the rest of the world, the thought of Adolf Hitler might be the first to gain control of a weapon this destructive would be terrifying to the United States. Right, then they decided that the administration of President Franklin D. Roosevelt must be warned about the dangers and that the United States must begin its research department. As the planned gave way, Einstein was to write a letter to President Franklin D. Roosevelt about the possibilities and dangers of the atomic weapons, and later was taken to the president.
degrees of Bachelor of Science in 1936 and Doctor of Philosophy in 1937. Since that time
His father had planned for him to follow him in a career in the clergy, but Lee wanted to go to school for science and, in 1893, enrolled at the Sheffield Scientific School of Yale University, one of the few institutions in the United States then offering a first-class scientific education. (Kraeuter, 74). De Forest went on to earn the Ph.D. in physics in 1899, with the help of scholarships, and money his parents made by working odd jobs. By this time he had become interested in electricit...
Carl Sagan: astronomer, astrophysicist, cosmologist, author, skeptic, and visionary. The middle of the twentieth century was clad in scientific advancements that opened up the realm of our universe to the world. At the head of this exploration was Carl Sagan, a pioneer of sorts. Aside from his countless contributions to the scientific community, he backed a new understanding of the cosmos to the more pedestrian population of the world.
Today, I will be introducing you to my new invention, as well as giving you a look at myself and my previous inventions so that you will have a good perspective about how profitable your investment will end up being.
Benjamin Franklin was self educated. Because of this, he earned honorary degrees from Harvard, Yale, Oxford University, and University of St. Andrews. In 1749 he wrote a pamphlet concerning the education of youth in Pennsylvania. That is how the University of Pennsylvania was established.
At 22, after two-thirds of a year at Berea College in West Virginia, he returned to the coalmines and studied Latin and Greek between trips to the mineshafts. He then went on to the University of Chicago, where he received bachelors and master's degrees, and Harvard University, where he became the second black to receive a doctorate in history.

"Were we to seize and eliminate from our industrial world the results of Mr. Tesla's work, the wheels of industry would cease to turn, our electric cars and trains would stop, our towns would be dark, our mills would be dead and idle. Yes, so far reaching is his work that it has become the warp and woof of industry... His name marks an epoch in the advance of electrical science.
Carl Sagan is known as one of the most famous scientists of all time. He revolutionized how the world looked at space and the search for intelligent life beyond our planet. The author of many books, he is most known for Contact (which was adapted into a movie) and for the PBS documentary Cosmos. As one of America's most famous astronomers and science-fiction writers, Carl Sagan turned a life of science into one of the most critically successful scientific careers of the 20th century.
In our educational system, students are not taught fully about a subject. While in Brazil, Feynman asked a student some questions after his exam that regarded his exam responses and he could not apply his calculations
Nikola Tesla was born midnight on July 10, 1856, in Smiljan, Lika, which at that time was part of the Austrian-Hungarian Empire, which is now known as Croatia. His father was named Milutin Tesla and he was a Serbian Orthodox Priest. Djuka Mandic was his mother and she invented household appliances. Tesla was the fourth child of five, having one older brother and three younger sisters. In 1873, Tesla studied at the the Polytechnic Institute in Graz, Austria and the University of Prague. At first, he wanted to pursue in physics and mathematics, but shortly after he became extremely interested in electricity. He began studying alternating current their also. Supposedly he had a photographic memory being able to memorize complete books. In December 1878, he left Graz and his family. In 1881, he started his career as an electrical engineer working for a telephone company in Budapest. It was around that time that Tesla was able to discover the solution for the rotating magnetic field. He was able to describe the basics of the induction motor to his peers. Later his alternating current induction motor would be considered one of the ten greatest discoveries of all time. Before coming to America, Tesla joined the Continental Edison Company in Paris where he designed. In February 1882, Tesla discovered the rotating magnetic field, an important principle in physics and it was also the start to pretty much all devices that use alternating current. In 1883, he secretly built a prototype of the induction motor which he was able to run successfully. Nobody in Europe cared about promoting his unqualified device, Tesla then accepted an offer to work for Thomas Edison in New York. His childhood dream was to come to America and to be able to grasp ...
Nikola Tesla was born on July 10, 1856 in Smiljan, Lika. His father, Milutin Tesla was a Serbian Orthodox Priest and his mother Djuka Mandic was an inventor in her own line of household appliances. Tesla studied at the Realschule, Karlstadt in 1873, the Polytechnic Institute in Graz, Austria and the University of Prague. At first, he intended to specialize in physics and mathematics, but soon he became fascinated with electricity. He began his career as an electrical engineer with a telephone company in Budapest in 1881. It was there, as Tesla was walking with a friend through the city park that the elusive solution to the rotating magnetic field flashed through his mind. With a stick, he drew a diagram in the sand explaining to his friend the principle of the induction motor. Before going to America, Tesla joined Continental Edison Company in Paris where he designed dynamos. While in Strassbourg in 1883, he privately built a prototype of the induction motor and ran it successfully. Soon after Tesla accepted an offer to work for Thomas Edison in New York. One of his childhood dreams was to come to America to harness the power of Niagara Falls. Young Nikola Tesla came to the United States in 1884. He spent the next 59 years of his life living in New York. Tesla set about improving Edison’s line of dynamos while working in Edison’s lab in New Jersey. he introduced his motors and electrical systems in a classic paper, “A New System of Alternating Current Motors and Transformers” which he delivered before the American Institute of Electrical Engineers in 1888. One of the most impressed was the industrialist and inventor George Westinghouse. One day he visited Tesla’s laboratory and was amazed at what he saw. Tesla had constructed a model polyphase system consisting of an alternating current dynamo, step-up and step-down transformers and A.C. motor at the other end. The perfect partnership between Tesla and Westinghouse for the nationwide use of electricity in America had begun. In February 1882, Tesla discovered the rotating magnetic field, a fundamental principle in physics and the basis of nearly all devices that use alternating current. Tesla brilliantly adapted the principle of rotating magnetic field for the construction of alternating current induction motor and the polyphase system for the generation, transmission, distribution and use of electrical power. Tesla’s A.C. induction motor is widely used throughout the world in industry and household appliances.
Though Einstein was one of the greatest contributors to physical science of our times, he was by no means the most brilliant theorist or experimenter. Competent specialists within the field of physics could have better accomplished some of his mathematical deductions. In fact, he needed the assistance of a friend, mathematician Marcel Grossman, to wield the tools necessary to develop his general theory of relativity. Einstein shined brightest within a theoretical context, but, despite the fact that his relativistic theories were most revolutionary, the study of quantum mechanics made a larger impact on the way physics is studied today. What, then, set Einstein apart? Curiosity was the key factor. As Einstein said, "I have no special gift - I am o...
Ernest Rutherford is considered the father of nuclear physics. Indeed, it could be said that Rutherford invented the very language to describe the theoretical concepts of the atom and the phenomenon of radioactivity. Particles named and characterized by him include the alpha particle, beta particle and proton.
