Karl Guthe Jansky - Karl Guthe Jansky Karl Guthe Jansky (October 22 1905 - February 14 1950), was the American physicist and radio engineer who in 1932 discovered that the Milky Way galaxy emanates radio waves; he did not follow up his discovery, but it marked the birth of radio astronomy. Jansky was born in Norman, Oklahoma, and studied at the University of Wisconsin where he received his Bachelor of Science degree in Physics in 1927. In 1928 he joined the Bell Telephone Laboratories in Holmdel, New Jersey. Bell Labs wanted to investigate using "short waves" (wavelengths of about 10-20 meters) for transatlantic radio telephone service. Jansky was assigned the job of investigating the sources of static that might interfere with radio voice transmissions. He built an antenna designed to.

Radio astronomy - him, primarily because research of cosmic signals did not exist (what is known today as radio astronomy), and the community of science rejected Tesla's data. Tesla spent the latter part of his life trying to signal Mars. One of the earliest modern investigations into extraterrestrial sources of radio waves were by Karl Guthe Jansky, an engineer with Bell Telephone Laboratories, in the early 1930s. Following World War II, substantial improvements in radio astronomy technology were made by astronomers in Europe and the United States, and the field of radio astronomy began to blossom. Developments Radio astronomy has led to substantial increases in astronomical knowledge, particularly with the discovery of several classes of new objects, including pulsars, quasars and radio galaxies. Such objects represent some of the most extreme and energetic physical.

Jansky - Jansky The jansky (Jy), is sometimes called the flux unit, is the unit used mostly in radio astronomy to measure the strength, or more precisely the flux density, of radio signals from space. When comparing flux densities measured in other wavelengths, all fluxes are usually converted to janskies. In measuring signal strength, it's necessary to take into account both the area of the receiving antenna and the width of the frequency band in which the signal occurs. Accordingly, one jansky equals a flux of 10-26 watts per square meter of receiving area per hertz of frequency band (W/m2Hz). Although it is not an SI unit, the jansky is approved by the International Astronomical Union and is widely used by astronomers. The brightest radio sources have flux.
Grote Reber - one of the pioneers of radio astronomy. He was instrumental in repeating Karl Jansky's pioneering but somewhat simple work, and conducted the first swky survey in the radio frequencies. Reber was born and raised in Chicago, and graduated from the Illinois Institute of Technology in 1933 with a degree in radio engineering. He was a ham radio operator, and worked for various radio manufacturers in Chicago from 1933 to 1947. When he learned of Jansky's work in 1933, he decided this was the field he wanted to work in, and applied to Bell Labs where Jansky was no working. However this was during the height of the Great Depression and there were no jobs available. Instead Reber decided to build his own radio telescope in his back yard in Wheaton, a.

Bell Labs - behavioral sciences, and computer programming theory. Systems engineering concerned itself with conceiving the highly complex systems that make up the telecommunication networks. Development, by far the largest of Bell Labs' activities designed the specific systems -- both hardware and software -- needed to build the Bell System's telecommunications networks. In 1933, Karl Jansky in his work for Bell Labs investigating the origins of static on long distance communications, discovered that radio waves were being emitted from the centre of the galaxy -- the founding of radio astronomy, though Bell did not pursue this, being more focussed on the problems of telecommunications. The transistor was invented by Bell Labs in 1947. The people responsible for the discovery, John Bardeen, William Bradford Shockley, and Walter Houser Brattain, won the Nobel Prize in Physics.

Karl Krumbacher - Karl Krumbacher Karl Krumbacher (1856-1909), German Byzantine scholar, was born at Kurnach in Bavaria on September 23 1856. He was educated at the universities of Munich and Leipzig, and held the professorship of the middle age and modern Greek language and literature in the former from 1897 to his death. His greatest work is his Geschichte der byzantinischen Literatur von Justinian bis zum Ende des Ostroemischen Reiches (from Justinian to the fall of the Eastern Empire, 1453), a second edition of which was published in 1897, with the collaboration of A. Ehrhard (section on theology) and H Gelzer (general sketch of Byzantine history, AD 395-1453). The value of the work is greatly enhanced by the elaborate bibliographies contained in the body of the work and in.
Karl Friedrich Bahrdt - Karl Friedrich Bahrdt Karl Friedrich Bahrdt (August 25, 1741 - April 23, 1792), German theologian and adventurer, was born at Bischofswerda, where his father, afterwards professor, canon and general superintendent at Leipzig, was pastor. At the age of sixteen young Bahrdt, a precocious lad whose training had been grossly neglected, began to study theology under the orthodox mystic Christian August Crusius (1715-1775), who in 1757 had become first professor in the theological faculty. The boy varied the monotony of his studies by pranks which revealed his unbalanced character, including an attempt to raise spirits with the aid of Dr Faust's Höllenzwang. His orthodoxy was, however, unimpeachable, his talent conspicuous, and in 1761 he was appointed lecturer on biblical exegesis, and preacher (Katechet) at the church of.
Karl Menger - Karl Menger Karl Menger (January 13 1902 - October 5 1985) was a mathematician of great scope and depth. He did work on Algebras, Curve and Dimension Theory, and Geometries. His most famous popular contribution was the Menger Sponge (mistakenly known as Sierpinski's Sponge), a three dimensional version of Sierpinski's Carpet. It is also related to the Cantor Set and the Sierpinski Square. See Also http://www.iit.edu/~am/Menger/menger.html You may be looking for the article on his father, the economist Carl Menger..
Karl of Austria - Karl of Austria Karl of Austria (also known in English as Charles) Karl Franz Josef Ludwig Hubert Georg Maria von Habsburg (August 17, 1887 - April 1, 1922) was the last Emperor of Austria and the last King of Hungary (as Charles IV of Hungary) and of the Habsburg Dynasty. He reigned from 1916 until his abdication on November 11, 1918. He sought to reclaim the throne of Hungary in the early 1920s. Karl has generally been seen by historians as an honourable figure who tried as emperor-king to halt World War I. On 14 April 2003 the Vatican's Congregation for the Causes of Saints, in the presence of Pope John Paul II, promulgated Karl of Austria's "heroic virtues", a step on the road to sainthood.

He was elected to the Federal Council of Switzerland on December 10, 1940 and handed over office on December 31, 1954. He was affiliated to the Free Democratic Party of Switzerland. During his office time he held the Department of Defence; Military Department. He was president of Switzerland twice in 1946 and 1952. Predecessor: Johannes Baumann Successor: Giuseppe Lepori.
Karl Schwarzschild - Karl Schwarzschild Karl Schwarzschild (October 9, 1873 - May 11, 1916) was a noted German physicist and astronomer. He was born in Frankfurt am Main. Something of a child prodigy he had a paper on orbits published when he was only sixteen. He studied at Strasbourg and Munich, obtaining his doctorate in 1896 for a work on Jules Henri Poincaré's theories. From 1897 on he worked as assistant at the Kufner Sternwarte in Vienna, where he developed a formula to calculate the properties of photographic material involving an exponent now know as the Schwarzschild-exponent (p in formula below). From 1901 until 1909 he was a professor at the prestigious institute at Göttingen, where he had the opportunity to work with some significant figures including David Hilbert.
