Lawrence Roberts (scientist)
Lawrence Gilman Roberts (December 21, 1937 – December 26, 2018) was an American engineer who received the Draper Prize in 2001 "for the development of the Internet", and the Principe de Asturias Award in 2002. As a program manager and later office director at the Advanced Research Projects Agency, Roberts and his team created the ARPANET using packet switching techniques invented by British computer scientist Donald Davies and American Paul Baran. The ARPANET, which was built by the Massachusetts-based company Bolt Beranek and Newman (BBN), was a predecessor to the modern Internet. He asked Leonard Kleinrock to apply mathematical models to simulate the performance of the network. Roberts later served as CEO of the commercial packet-switching network Telenet. Early life and education Roberts, who was known as Larry, was born and raised in Westport, Connecticut. He was the son of Elizabeth (Gilman) and Elliott John Roberts, both of whom had doctorates in chemistry. It is said ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westport, Connecticut
Westport is a town in Fairfield County, Connecticut, United States, along the Long Island Sound within Connecticut's Gold Coast. It is northeast of New York City. The town had a population of 27,141 according to the 2020 U.S. Census. History The earliest known inhabitants of the Westport area as identified through archaeological finds date back 7,500 years. Records from the first white settlers report the Pequot Indians living in the area which they called ''Machamux'' translated by the colonialists as ''beautiful land''. Settlement by colonialists dates back to the five '' Bankside Farmers''; whose families grew and prospered into a community that continued expanding. The settlers arrived in 1693, having followed cattle to the isolated area. The community had its own ecclesiastical society, supported by independent civil and religious elements, enabling it to be independent from the Town of Fairfield. As the settlement expanded its name changed: it was briefly known as "Ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Research Projects Agency
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource ''The Economist'' has called DARPA the agency "that shaped the modern world," and pointed out that " Moderna's COVID-19 vaccine sits alongside weather satellites, GPS, drones, stealth technology, voice interfaces, the personal computer ...

Wired Magazine
''Wired'' (stylized as ''WIRED'') is a monthly American magazine, published in print and online editions, that focuses on how emerging technologies affect culture, the economy, and politics. Owned by Condé Nast, it is headquartered in San Francisco, California, and has been in publication since March/April 1993. Several spin-offs have been launched, including ''Wired UK'', ''Wired Italia'', ''Wired Japan'', and ''Wired Germany''. From its beginning, the strongest influence on the magazine's editorial outlook came from founding editor and publisher Louis Rossetto. With founding creative director John Plunkett, Rossetto in 1991 assembled a 12-page prototype, nearly all of whose ideas were realized in the magazine's first several issues. In its earliest colophons, ''Wired'' credited Canadian media theorist Marshall McLuhan as its "patron saint". ''Wired'' went on to chronicle the evolution of digital technology and its impact on society. ''Wired'' quickly became recognized ...

Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and ele ...

Master's Degree
A master's degree (from Latin ) is an academic degree awarded by universities or colleges upon completion of a course of study demonstrating mastery or a high-order overview of a specific field of study or area of professional practice. A master's degree normally requires previous study at the bachelor's degree, bachelor's level, either as a separate degree or as part of an integrated course. Within the area studied, master's graduates are expected to possess advanced knowledge of a specialized body of and applied topics; high order skills in [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bachelor's Degree
A bachelor's degree (from Middle Latin ''baccalaureus'') or baccalaureate (from Modern Latin ''baccalaureatus'') is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to six years (depending on institution and academic discipline). The two most common bachelor's degrees are the Bachelor of Arts (BA) and the Bachelor of Science (BS or BSc). In some institutions and educational systems, certain bachelor's degrees can only be taken as graduate or postgraduate educations after a first degree has been completed, although more commonly the successful completion of a bachelor's degree is a prerequisite for further courses such as a master's or a doctorate. In countries with qualifications frameworks, bachelor's degrees are normally one of the major levels in the framework (sometimes two levels where non-honours and honours bachelor's degrees are considered separately). However, some qualifications titled bachelo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Girl Scouts Of The USA
Girl Scouts of the United States of America (GSUSA), commonly referred to as simply Girl Scouts, is a youth organization for girls in the United States and American girls living abroad. Founded by Juliette Gordon Low in 1912, it was organized after Low met Robert Baden-Powell, 1st Baron Baden-Powell, Robert Baden-Powell, the founder of Scouting, in 1911. Upon returning to Savannah, Georgia, Savannah, Georgia, she telephoned a distant cousin, saying, "I've got something for the girls of Savannah, and all of America, and all the world, and we're going to start it tonight!" Girl Scouts prepares girls to empower themselves and promotes compassion, courage, confidence, character, leadership, entrepreneurship, and active citizenship through activities involving camping, community service, learning first aid, and earning badges by acquiring practical skills. Girl Scouts' achievements are recognized with various special awards, including the Girl Scout Gold, Silver, and Bronze Awards. ...

Tesla Coil
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low- current, high-frequency alternating-current electricity. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits. Tesla used these circuits to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high-frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in spark-gap radio transmitters for wireless telegraphy until the 1920s, and in medical equipment such as electrotherapy and violet ray devices. Today, their main usage is for entertainment and educational displays, although small coils are still used as leak detectors for high-vacuum systems. Originally, Tesla coils used fixed spark gaps or rotary spark gaps to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemistry
Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth ( botany), the formation of igneous rocks ( geology), how atmospheric ozone is formed and how environmental pollutants are degraded ( ecology), the properties of the soil on the moon ( cosmochemistry), how medications work ( pharmacology), and how to collec ...

Leonard Kleinrock
Leonard Kleinrock (born June 13, 1934) is an American computer scientist and a long-tenured professor at UCLA's Henry Samueli School of Engineering and Applied Science. In the early 1960s, Kleinrock pioneered the application of queueing theory to model delays in message switching networks in his Ph.D. thesis, published as a book in 1964. He later published several of the standard works on the subject. In the early 1970s, he applied queueing theory to model the performance of packet switching networks. This work played an influential role in the development of the ARPANET, the precursor to the Internet. He supervised many graduate students who worked on the communication protocols for internetworking which led to the Internet. His theoretical work on hierarchical routing in the late 1970s with student Farouk Kamoun remains critical to the operation of the Internet today. Education and career Leonard Kleinrock was born in New York City on June 13, 1934, to a Jewish family, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
