Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

SDS-PAGE
SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa. The combined use of sodium dodecyl sulfate (SDS, also known as sodium lauryl sulfate) and polyacrylamide gel allows to eliminate the influence of structure and charge, and proteins are separated solely on the basis of differences in their molecular weight. Properties SDS-PAGE is an electrophoresis method that allows protein separation by mass. The medium (also referred to as ′matrix′) is a polyacrylamide-based discontinuous gel. The polyacrylamide-gel is typically sandwiched between two glass plates in a slab gel. Although tube gels (in glass cylinders) were used historically, they were rapidly made obsolete with the invention of the more convenient slab gels. In addition, SDS (sodium dodecyl sulfate) is used. About 1.4 grams of S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Word Processor
A word processor (WP) is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features. Word processor (electronic device), Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers. The functions of a word processor program fall somewhere between those of a simple text editor and a fully functioned desktop publishing program. However, the distinctions between these three have changed over time and were unclear after 2010. Background Word processors did not develop ''out'' of computer technology. Rather, they evolved from mechanical machines and only later did they merge with the computer field. The history of word processing is the story of the gradual automation of the physical aspects of writing and editing, and then to the refinement of the technology to make it available to corporations and Indi ...

Bomber (novel)
''Bomber'' is a novel by Len Deighton that was published in the United Kingdom in 1970. It is the fictionalised account of "the events relating to the last flight of an RAF Bomber over Germany on the night of June 31st, 1943", a deliberately impossible date, in which an Royal Air Force, RAF bombing raid on the Ruhr area of western Germany goes wrong. In each chapter, the Plot (narrative), plot is advanced by seeing the progress of the day through the eyes of protagonists on both sides of the conflict. ''Bomber'' was the first novel to be written on a word processor, the IBM MT/ST. Plot summary Sam Lambert is an experienced RAF Bomber Command Avro Lancaster pilot based in East Anglia. He has flown almost fifty bombing missions over Germany as part of the Combined Bomber Offensive since the start of the war. As Lambert nears his tour's end, he is developing signs of exhaustion. Lambert is an accomplished cricketer and the station commander needs his participation to assure victory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Len Deighton
Leonard Cyril Deighton (; born 18 February 1929) is a British author. His publications have included cookery books, history and military history, but he is best known for his spy novels. After completing his national service in the Royal Air Force, Deighton attended art school in London, and graduated from the Royal College of Art in 1955. He had several jobs before becoming a book and magazine illustrator—including designing the cover for first UK edition of Jack Kerouac's 1957 work ''On the Road''. He also worked for a period in an advertising agency. During an extended holiday in France he wrote his first novel, ''The IPCRESS File'', which was published in 1962, and was a critical and commercial success. He wrote several spy novels featuring the same central character, a working-class intelligence officer, cynical and tough. Between 1962 and 1966 Deighton was the food correspondent for ''The Observer'' and drew cookstrips—black and white graphic recipes with a limited nu ...

Datapoint
Datapoint Corporation, originally known as Computer Terminal Corporation (CTC), was a computer company based in San Antonio, Texas, United States. Founded in July 1968 by Phil Ray and Gus Roche, its first products were, as the company's initial name suggests, computer terminals intended to replace Teletype machines connected to time sharing systems. Background From the mid-1960s, engineers (John) Phil Ray and Austin O. "Gus" Roche were working for General Dynamics Dynatronic Division in Florida, as part of a computing contract team for NASA to enable President John F. Kennedy's vision of putting a man on the moon. At the time, mainframe computers were large room-filling pieces of equipment, for which data was input using dumb and noisy Teletype terminals. On the advice of one of his tutors from the University of Texas, Ray and Roche decided to develop a quieter and smaller input device based on using a television set screen.

Computer Terminal
A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing data from, a computer or a computing system. The teletype was an example of an early-day hard-copy terminal and predated the use of a computer screen by decades. Early terminals were inexpensive devices but very slow compared to punched cards or paper tape for input, yet as the technology improved and video displays were introduced, terminals pushed these older forms of interaction from the industry. A related development was time-sharing systems, which evolved in parallel and made up for any inefficiencies in the user's typing ability with the ability to support multiple users on the same machine, each at their own terminal or terminals. The function of a terminal is typically confined to transcription and input of data; a device with significant local, programmable data-processing capability may be called a "smart terminal" or fat client.

Datapoint 2200
The Datapoint 2200 was a mass-produced programmable computer terminal usable as a computer, designed by Computer Terminal Corporation (CTC) founders Phil Ray and Gus Roche and announced by CTC in June 1970 (with units shipping in 1971). It was initially presented by CTC as a versatile and cost-efficient terminal for connecting to a wide variety of mainframes by loading various terminal emulations from tape rather than being hardwired as most contemporary terminals, including their earlier Datapoint 3300. However, Dave Gust, a CTC salesman, realized that the 2200 could meet Pillsbury Foods's need for a small computer in the field, after which the 2200 was marketed as a stand-alone computer. Its industrial designer John "Jack" Frassanito has later claimed that Ray and Roche always intended the Datapoint 2200 to be a full-blown personal computer, but that they chose to keep quiet about this so as not to concern investors and others. Also significant is the fact that the terminal's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Mouse
A computer mouse (plural mice, sometimes mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was in 1968. Mice originally used two separate wheels to track movement across a surface: one in the X-dimension and one in the Y. Later, the standard design shifted to utilize a ball rolling on a surface to detect motion. Most modern mice use optical sensors that have no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range radio communication with the connected system. In addition to moving a cursor, computer mice have one or more buttons to allow operations such as the selection of a menu item on a display. Mice often also feature ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Douglas Engelbart
Douglas Carl Engelbart (January 30, 1925 – July 2, 2013) was an American engineer and inventor, and an early computer and Internet pioneer. He is best known for his work on founding the field of human–computer interaction, particularly while at his Augmentation Research Center Lab in SRI International, which resulted in creation of the computer mouse, and the development of hypertext, networked computers, and precursors to graphical user interfaces. These were demonstrated at The Mother of All Demos in 1968. Engelbart's law, the observation that the intrinsic rate of human performance is exponential, is named after him. NLS, the "oN-Line System," developed by the Augmentation Research Center under Engelbart's guidance with funding primarily from ARPA (as DARPA was then known), demonstrated numerous technologies, most of which are now in widespread use; it included the computer mouse, bitmapped screens, hypertext; all of which were displayed at "The Mother of All Dem ...

Jef Raskin
Jef Raskin (born Jeff Raskin; March 9, 1943 – February 26, 2005) was an American human–computer interface expert best known for conceiving and starting the Macintosh project at Apple in the late 1970s. Early life and education Jef Raskin was born in New York City to a secular Jewish family, whose surname is a matronymic from "Raske", Yiddish nickname for Rachel. He received a BA in mathematics and a BS in physics with minors in philosophy and music from Stony Brook University. In 1967, he received a master's degree in computer science from Pennsylvania State University, after having switched from mathematical logic due to differences of opinion with his advisor. Even though he had completed work for his PhD, the university was not accredited for a PhD in computer science. The first original computer application he wrote was a music application as part of his master's thesis. Raskin later enrolled in a graduate music program at the University of California, San Diego ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
