William Shurcliff
William Asahel Shurcliff (March 27, 1909 – June 20, 2006) was an American physicist. Biography He received his BA cum laude in 1930, a PhD in Physics in 1934, and a degree in Business Administration in 1935, all from Harvard University. In the 1930s he worked at the Spectrophotometric Laboratory at the Calco Chemical Division of the American Cyanamid Company. Atomic bomb In 1942 he joined the staff of the Office of Scientific Research and Development, where he worked in the Liaison Office, processing technical information obtained from overseas and routing it to divisions within US government research where it could be useful. In May 1942 he was chosen by his boss, Vannevar Bush, to be part of S-1 Section, which would become the Manhattan Project to make the atomic bomb. Shurcliff's role was specifically to be a censor of patents: he would review patent applications from the private sector which appeared to impinge on topics being developed in secret by the government, and put th ...

Cum Laude
Latin honors are a system of Latin phrases used in some colleges and universities to indicate the level of distinction with which an academic degree has been earned. The system is primarily used in the United States. It is also used in some Southeastern Asian countries with European colonial history, such as Indonesia and the Philippines, although sometimes translations of these phrases are used instead of the Latin originals. The honors distinction should not be confused with the honors degrees offered in some countries, or with honorary degrees. The system usually has three levels of honor: ''cum laude'', ''magna cum laude'', and ''summa cum laude''. Generally, a college or university's regulations set out definite criteria a student must meet to obtain a given honor. For example, the student might be required to achieve a specific grade point average, submit an honors thesis for evaluation, be part of an honors program, or graduate early. Each school sets its own standards. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Superinsulation
Superinsulation is an approach to building design, construction, and retrofitting that dramatically reduces heat loss (and gain) by using much higher levels of insulation and airtightness than normal. Superinsulation is one of the ancestors of the passive house approach. Definition There is no universally agreed definition of superinsulation, but superinsulated buildings typically include: * Very high levels of insulation, typically R-40 (RSI-7) walls and R-60 (RSI-10.6) roof, corresponding to SI U-values of 0.15 and 0.1 W/(m²·K) respectively) * Details to ensure insulation continuity where walls meet roofs, foundations, and other walls * Airtight construction, especially around doors and windows to prevent air infiltration pushing heat in or out * a heat recovery ventilation system to provide fresh air * No large windows facing any particular direction * Much smaller than conventional heating system, sometimes just a small backup heater Nisson & Dutt (1985) suggest that ...

Passive Solar Building Design
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices. The key to designing a passive solar building is to best take advantage of the local climate performing an accurate site analysis. Elements to be considered include window placement and size, and glazing type, thermal insulation, thermal mass, and shading. Passive solar design techniques can be applied most easily to new buildings, but existing buildings can be adapted or "retrofitted". Passive energy gain ''Passive solar'' technologies use sunlight without active mechanical systems (as contrasted to ''active solar'', which uses thermal collectors). Such technologies convert sunlight into usable heat (in water, air, and thermal mass), cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bulletin Of The Atomic Scientists
The ''Bulletin of the Atomic Scientists'' is a nonprofit organization concerning science and global security issues resulting from accelerating technological advances that have negative consequences for humanity. The ''Bulletin'' publishes content at both a free-access website and a bi-monthly, nontechnical academic journal. The organization has been publishing continuously since 1945, when it was founded by former Manhattan Project scientists as the ''Bulletin of the Atomic Scientists of Chicago'' immediately following the atomic bombings of Hiroshima and Nagasaki. The organization is also the keeper of the symbolic Doomsday Clock, the time of which is announced each January. Background One of the driving forces behind the creation of the ''Bulletin'' was the amount of public interest surrounding atomic energy and rapid technological change at the dawn of the Atomic Age. In 1945 the public interest in atomic warfare and weaponry inspired contributors to the ''Bulletin'' to at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anti-Concorde Project
The Anti-Concorde Project, founded by environmental activist Richard Wiggs, challenged the idea of supersonic passenger transport, and curtailed Concorde's commercial prospects. When Concorde entered service in 1976, of the 74 options (non-binding orders, from 16 airlines) held at the time of the first flight, only those for the state airlines of Britain (BOAC) and France (Air France) were taken up, so that only 20 were built, although flights were also flown for Braniff International and Singapore Airlines. It triggered research into the factors affecting the creation of sonic booms, which led to the Shaped Sonic Boom Demonstration which achieved their goal of reducing the intensity of sonic booms (by about one-third), and echoed public concern about aircraft noise that resulted in more restrictive noise limits for aircraft and airport operations, as well as changes in both operating procedures and aircraft design to further reduce noise levels. Overview In the late 1950s, fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambridge Electron Accelerator
Cambridge ( ) is a university city and the county town in Cambridgeshire, England. It is located on the River Cam approximately north of London. As of the 2021 United Kingdom census, the population of Cambridge was 145,700. Cambridge became an important trading centre during the Roman and Viking ages, and there is archaeological evidence of settlement in the area as early as the Bronze Age. The first town charters were granted in the 12th century, although modern city status was not officially conferred until 1951. The city is most famous as the home of the University of Cambridge, which was founded in 1209 and consistently ranks among the best universities in the world. The buildings of the university include King's College Chapel, Cavendish Laboratory, and the Cambridge University Library, one of the largest legal deposit libraries in the world. The city's skyline is dominated by several college buildings, along with the spire of the Our Lady and the English Martyrs ...

Supersonic Aircraft
A supersonic aircraft is an aircraft capable of supersonic flight, that is, flying faster than the speed of sound (Mach number 1). Supersonic aircraft were developed in the second half of the twentieth century. Supersonic aircraft have been used for research and military purposes, but only two supersonic aircraft, the Tupolev Tu-144 (first flown on December 31, 1968) and the Concorde (first flown on March 2, 1969), ever entered service for civil use as airliners. Fighter jets are the most common example of supersonic aircraft. The aerodynamics of supersonic flight is called compressible flow because of the compression associated with the shock waves or " sonic boom" created by any object traveling faster than sound. Aircraft flying at speeds above Mach 5 are called hypersonic aircraft. History The first aircraft to fly supersonic in level flight was the American Bell X-1 experimental plane which was powered by a thrust rocket powered by liquid oxygen and ethyl alcoho ...
