Joseph Henry 1797-1878 Christian Andreas Doppler 1803-1853 Felix Bloch 1905-1983 Thomas Young 1773-1829 Edward Witten Ralph C. Merkle Joseph Henry The leading American scientist after Benjamin Franklin, his chief scientific contributions were in the field of Electromagnetism. Where he discovered the phenomenon of self- inductance. The unit of inductance, called the Henry, immortalizes his Name. Henry was the son of a laborer in Albany, New York he worked in a general store with his mother. When he got a little bit older he became an actor then a scientist.
Christian Doppler His family were stonemasons who had a successful business in Salzburg, Austria. Doppler began his studies in the Vienna Polytechnic Institute in 1822. He excelled in his mathematical and other studies and graduated in 1825. After that he went to the University of Vienna and graduated in 1829. He was appointed to assistant to the professor of higher mathematics and mechanics and made a contribution to the theory of parallels. Felix Bloch He was born in in Zurich, Switzerland on.
October 23, 1905. Planning originally to. become an engineer, he entered directly. In the Federal Institute of Technology in. Zurich.
After one year in engineering he. decided to study physics instead. He. received his degree of Doctor of. Philosophy in the summer of 1928. with a dissertation dealing with the.
quantum mechanics of electrons in. crystals and developing the theory of. metallic conduction. Thomas Young English physicist who determined the wavelengths of members of the visible spectrum using diffraction experiments in 1820.
The Term Paper on Henry David Thoreau 7
“Simplify! was Thoreau’s motto” in his life (Stanley 20). He showed people how to live simple life by living a simple life in Walden. Due to Thoreau’s efforts and works on nature people considers a nature an important part in their lives, as a result nature became one of the top topics in 21st century. Henry David Thoreau was born on July 12, 1817, in Concord, Massachusetts ...
In order to explain the double refraction discovered by Barth olin, he correctly concluded that light must be a transverse wave. His wave theory also explained the interference of light. He projected ultraviolet rays on silver chloride-covered paper and showed that interference resulted. He first hypothesized then experimentally demonstrated that light. Ralph C. Merkle His current research focuses on computer security.
We are increasingly dependent on computers for everything — finances, communications, transportation, manufacturing, our health and even our lives — and our dependence on computers is increasing exponentially. Yet today viruses and worms are rampant, we ” re flooded with spam, identity theft is common, and hackers can commandeer computers almost at will to disrupt and shut down vital services. Edward Witten Edward Witten studied at Brandeis University and received his B. A. in 1971.
From there he went to Princeton receiving his M. A. in 1974 and his Ph. D.
in 1976. After completing his doctorate, Witten went to Harvard where he was postdoctoral fellow during session 1976-77 and then a Junior Fellow from 1977 to 1980. In September 1980 Witten was appointed professor of Physics at Princeton. He was awarded a MacArthur Fellowship in 1982 and remained as professor of Physics at Princeton until 1987 when he was appointed as a Professor in the School of Natural Sciences at the Institute for Advanced Study. Basically Witten is a mathematical physicist and he has a wealth of important publications which are properly in physics the great one.
