Charles Fisk (organ Builder)
Charles Brenton Fisk (February 7, 1925 – December 16, 1983) was an American pipe organ builder who was one of the first to reintroduce mechanical tracker actions in modern organ building over electro-pneumatic actions. Born in Washington D. C., he developed an early fascination with organs and electronics. After graduating high school, he was drafted into World War II as a technician. He was later transferred to Los Alamos Laboratory, where he unknowingly contributed to the Manhattan Project and subsequently the atomic bomb Fat Man. Afterwards, Fisk initially pursued a career in atomic physics, earning a degree from Harvard University. However, he soon decided to abandon physics and dedicate himself to organbuilding. He took apprenticeship under John Swinford and Walter Holtkamp and made frequent trips to Europe to study European organs. Often associated with the Organ Reform Movement, he often incorporated historical features into his organs. Afterward he became a partner ...

The Cambridge School Of Weston
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee ...

Tube Amplifiers
A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s. Valve amplifiers can be used for applications such as guitar amplifiers, satellite transponders such as DirecTV and GPS, high quality stereo amplifiers, military applications (such as radar) and very high power radio and UHF television transmitters. History Origins Until the invention of the transistor in 1947, most practical high-frequency electronic amplifiers were made using thermionic valves. The simplest valve (named diode because it had two electrodes) was invented by John Ambrose Fleming while working for the Marconi Company in London in 1904. The diode conducted electricity in one direction only and was used as a radio detector and a rectifier. In 1906 Lee De Forest added a third el ...

Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude (magnitude of the voltage or current) of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. The amount of amplification provided by an amplifier is measured by its gain: the ratio of output voltage, current, or power to input. An amplifier is defined as a circuit that has a power gain greater than one. An amplifier can be either a separate piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are widely used in almost all electronic equipment. Amplifiers can be categorized in different ways. One is by the frequency of the electronic signal being amplified. For ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Museum Of Nuclear Science & History
The National Museum of Nuclear Science & History (formerly named National Atomic Museum) is a national repository of nuclear science information chartered by the 102nd United States Congress under Public Law 102-190, and located in unincorporated Bernalillo County, New Mexico, with an Albuquerque postal address.

Cambridge Common is a public park and National Historic Landmark in Cambridge, Massachusetts, United States. It is located near Harvard Square and borders on several parts of Harvard University. The north end of the park has a large playground. The park is maintained by the Cambridge Department of Public Works. History Cambridge Common was established in 1630 as a common area, intended to serve as grazing pasture for ox, sheep, and cows as well as a woodlot. It was also used as a military training ground. It originally extended from what is now Linnaean Street in the north all the way south to Harvard Square between Massachusetts Avenue and Garden Street, an area comprising roughly 85 acres. Public executions took place in the northern portion of this space, known as Gallows Hill, located today west of Massachusetts Avenue around Lancaster Street.

Christ Church (Cambridge, Massachusetts)
Christ Church, at Zero Garden Street in Cambridge, Massachusetts, U.S., is a parish of the Episcopal Diocese of Massachusetts. Built in 1760–61, it was designated a National Historic Landmark as one of the few buildings unambiguously attributable to Peter Harrison, the first formally trained architect to work in the British colonies. History The congregation was founded in 1759 by members of the King's Chapel who lived in Cambridge to have a church closer to their homes and to provide Church of England services to students at Harvard College across Cambridge Common. The church's first rector was East Apthorp, and most of the founding members lived along the nearby Tory Row, now called Brattle Street. The church was designed by noted colonial era architect Peter Harrison, who also designed the King's Chapel in Boston, and is one of a small number of surviving buildings attributable to him. It is built in Georgian style. Its wooden frame rests on a granite foundation b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
