John Bardeen - John Bardeen John Bardeen (May 23, 1908 - January 30, 1991) was a physicist who was the co-inventor of the transistor. He developed a fundamental theory for conventional superconductivity together with Cooper and Schrieffer; today known as the BCS theory. He was born in Madison, Wisconsin, and received his Bachelor's degree in Electrical Engineering from the University of Wisconsin in 1928. Bardeen studied Physics as a graduate student at Princeton, with Nobel Laureate Eugene Wigner. He received his PhD from Princeton in 1936. In 1956, Bardeen received the Nobel Prize in physics for the transistor. Amazingly, he received it again in 1972 for the BCS theory. No other physicist has received it twice. Bardeen was also an important advisor to the Xerox Corporation. Though quiet by.

BCS theory - effect, the two electrons are then held together with a certain binding energy. If this binding energy is higher than the energy provided by kicks from oscillating atoms in the conductor (which is true at low temperatures), then the electron pair will stick together and resist all kicks, thus not experiencing resistance. BCS theory was developed in 1957 by John Bardeen, Leon Cooper, and Robert Schrieffer, who received the Nobel Prize for Physics in 1972 as a result. In 1986, "high-temperature superconductivity" was discovered (i.e. superconductivity at temperatures considerably above the previous limit of about 30 K; up to about 130 K). It is believed that at these temperatures other effects are at play; these effects are not yet fully understood. (It is possible that these unknown effects also control superconductivity.
Bell Labs - 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 in 1956. Claude Shannon, working as a research mathematician, published "A Mathematical Theory of Communication" (1948) in the Bell System Technical Journal, which in part built on earlier work in information theory at Bell Labs by Nyquist and Hartley.

Timeline of computing 500 BC-1949 - positions of the Earth, Moon and Sun. 1500 Leonardo da Vinci produced drawings of a device consisting of interlocking cog wheels which could be interpreted as a mechanical calculator capable of addition and subtraction. A working model inspired by this plan was built in 1968 but it remains controversial whether Leonardo really had a calculator in mind (see [here].) 1614 Scotsman John Napier (1550-1617) published a paper outlining his discovery of the logarithm. Napier also invented an ingenious system of moveable rods (referred to as Napier's Rods or Napier's bones). These were based on logarithms and allowed the operator to multiply, divide and calculate square and cube roots by moving the rods around and placing them in specially constructed boards. 1623 Wilhelm Schickard (1592-1635), of Tübingen, Württemberg (now in Germany), built.
Transistor - through "brute force". Today transistors have replaced almost all electromechanical devices, most simple feedback systems, and appear in huge numbers in everything from computers to cars. Hand-in-hand with low cost has been the increasing move to "digitizing" all information. With transistorized computers offering the ability to quickly find (and sort) digital information, more and more effort was put into making all information digital. Today almost all media in modern society is delivered in digital form, converted and presented by computers. Common "analog" forms of information such a television or newspapers spend the vast majority of their time as digitial information, being converted to analog only for a small portion of the time. Invention The transistor was invented at Bell Laboratories in December 1947 (first demonstrated on December 23) by John Bardeen,.
Science in America - the US was left in a position of unchallenged scientific leadership. The public "loved" science, and the leadership was fond of funding it. By the mid-1950s the research facilities in the US were second to none, and scientists were drawn to the US for this reason alone. The changing pattern can be seen in the winners of the Nobel Prizes in physics and chemistry. During the first half-century of Nobel Prizes – from 1901 to 1950 – American winners were in a distinct minority in the science categories. Since 1950, Americans have won approximately half of the Nobel Prizes awarded in the sciences. American Applied Science During the 19th century, Britain, France, and Germany were at the forefront of new ideas in science and mathematics. But if the United States lagged.
Silicon Valley - of the Stanford Industrial Park, a series of small industrial buildings that were rented out at very low costs to technical companies. In 1954, the Honors Cooperative Program, today known as the co-op, was established to allow full-time employees of the companies to pursue graduate degrees from the University on a part-time basis. The initial companies signed five-year agreements in which they would pay double the tuition for each student in order to cover the costs. By the mid-1950s the infrastructure for what would later allow the creation of "the valley" was in a nascent stage due to Terman's efforts. It was in this atmosphere that a former Californian decided to move to the area. William Shockley had quit Bell Labs in 1953 in a disagreement over the way the transistor.
William Shockley - 12, 1989) was a physicist and co-inventor of the transistor with John Bardeen and Walter Houser Brattain. Born in London, England, to American parents, he was a descendant, on his father's side, of the American Mayflower pilgrims, John Alden and Priscilla Mullins, and his father was an alumnus of MIT. Raised in California, he received his Bachelor of Science degree from the California Institute of Technology in 1932 and his doctorate from MIT in 1936. After receiving his doctorate, he immediately joined a research group headed by Dr. C.J. Davisson at Bell Labs in New Jersey, and began moving up the management ladder. In the mid 1940's, Shockley's group, consisting of Bardeen and Brattain, sought a solid-state alternative to fragile glass vacuum tube amplifiers. Shockley insisted on working alone, leaving his.
