Richard Bolt
Richard Henry Bolt (April 22, 1911 – January 13, 2002) was an American physics professor at MIT with an interest in acoustics. He was one of the founders of the company Bolt, Beranek and Newman, which built the ARPANET, a forerunner of the Internet. Early life Bolt was born in Peking, China, where his parents were medical missionaries. His family returned to the U.S. in 1916 and settled in California. Bolt graduated from Berkeley High School, California in 1928 and went to college and graduate school at the University of California, Berkeley. Although he initially expected to major in either music or graphical design, he decided on architecture, in which he attained a BA in 1933. At that time, he had already developed an interest in acoustics, combining his interests for music, design and architecture. After his marriage to Katherine Mary Smith, right after his graduation in 1933, they made a honeymoon to Europe, where he became acquainted with a number of scientists f ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Master Of Arts
A Master of Arts ( la, Magister Artium or ''Artium Magister''; abbreviated MA, M.A., AM, or A.M.) is the holder of a master's degree awarded by universities in many countries. The degree is usually contrasted with that of Master of Science. Those admitted to the degree have typically studied subjects within the scope of the humanities and social sciences, such as history, literature, languages, linguistics, public administration, political science, communication studies, law or diplomacy; however, different universities have different conventions and may also offer the degree for fields typically considered within the natural sciences and mathematics. The degree can be conferred in respect of completing courses and passing examinations, research, or a combination of the two. The degree of Master of Arts traces its origins to the teaching license or of the University of Paris, designed to produce "masters" who were graduate teachers of their subjects.

Computer Modem
A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio. Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1,200 and 2,400 bit/s for asynchronous dial connections, 4,800 bit/s for synchrono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Watergate Tapes
The Nixon White House tapes are audio recordings of conversations between U.S. President Richard Nixon and Nixon administration officials, Nixon family members, and White House staff, produced between 1971 and 1973. In February 1971, a sound-activated taping system was installed in the Oval Office, including in Nixon's Wilson desk, using Sony TC-800B open-reel tape recorders to capture audio transmitted by telephone taps and concealed microphones. The system was expanded to include other rooms within the White House and Camp David. The system was turned off on July 18, 1973, two days after it became public knowledge as a result of the U.S. Senate Watergate Committee hearings. Nixon was not the first president to record his White House conversations; President Franklin D. Roosevelt recorded Oval Office press conferences for a short period in 1940. The tapes' existence came to light during the Watergate scandal of 1973 and 1974, when the system was mentioned during the televised ...

White House
The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800. The term "White House" is often used as a metonym for the president and his advisers. The residence was designed by Irish-born architect James Hoban in the neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800, using Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) added low colonnades on each wing that concealed stables and storage. In 1814, during the War of 1812, the mansion was set ablaze by British forces in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
