Memorial Drive (Cambridge)
Memorial Drive (colloquially referred to as Mem Drive) is a parkway along the north bank of the Charles River in Cambridge, Massachusetts, United States. It runs parallel to two major Boston parkways - Soldiers Field Road and Storrow Drive - which lie on the south bank of the river. The western terminus is in West Cambridge at Greenough Boulevard and Fresh Pond Parkway. The eastern terminus is at Main Street and the Longfellow Bridge near Kendall Square. Memorial Drive is designated as U.S. Route 3 for most of its length, except the easternmost which are designated as Massachusetts Route 3 (US 3 and Route 3 connect end-to-end and are treated as one continuous route by the state). Route 2 is cosigned with US 3 on Memorial Drive between the western terminus and the Boston University Bridge. History Formerly known as Charles River Road, the road was officially renamed "Memorial Drive" in 1923, when Charles River Park was taken over by the Metropolitan District Commission. It is n ...

Electronic Components
An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components and elements. Electronic components have a number of electrical terminals or leads. These leads connect to other electrical components, often over wire, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Basic electronic components may be packaged discretely, as arrays or networks of like components, or integrated inside of packages such as semiconductor integrated circuits, hybrid integrated circuits, or thick film devices. The following list of electronic components focuses on the discrete version of these components, treating such packages as component ...

Vacuum Tubes
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplification and current rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to the anode. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Tube
A gas-filled tube, also commonly known as a discharge tube or formerly as a Plücker tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope. Gas-filled tubes exploit phenomena related to electric discharge in gases, and operate by ionizing the gas with an applied voltage sufficient to cause electrical conduction by the underlying phenomena of the Townsend discharge. A gas-discharge lamp is an electric light using a gas-filled tube; these include fluorescent lamps, metal-halide lamps, sodium-vapor lamps, and neon lights. Specialized gas-filled tubes such as krytrons, thyratrons, and ignitrons are used as switching devices in electric devices. The voltage required to initiate and sustain discharge is dependent on the pressure and composition of the fill gas and geometry of the tube. Although the envelope is typically glass, power tubes often use ceramics, and military tubes often use glass-lined metal. Both hot cathode and cold cath ...

Babson College
Babson College is a private business school in Wellesley, Massachusetts. Established in 1919, its central focus is on entrepreneurship education. It was founded by Roger W. Babson as an all-male business institute, but became coeducational in 1970. History 20th century On September 3, 1919, with an enrollment of twenty-seven students, the Babson Institute held its first classes in the former home of Roger and Grace Babson on Abbott Road in Wellesley Hills. Roger Babson, the founder of the school, set out to distinguish the Babson Institute from colleges offering mainly instruction in business. The Institute provided intensive training in the fundamentals of production, finance and distribution in just one academic year, rather than four. The curriculum was divided into four subject areas: practical economics, financial management, business psychology and personal efficiency (which covered topics such as ethics, personal hygiene and interpersonal relationships). The program ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roger Babson
Roger Ward Babson (July 6, 1875 – March 5, 1967) was an American entrepreneur, economist, and business theorist in the first half of the 20th century. He is best remembered for founding Babson College. He also founded Webber College, now Webber International University, in Babson Park, Florida, and the defunct Utopia College, in Eureka, Kansas.
