1970 In Science
The year 1970 in science and technology involved some significant events, listed below. Astronomy and space exploration * February 11 – Japan becomes the fourth country to launch a satellite into orbit. * March 31 – Explorer I reentry (after 12 years in orbit) * April 11 – Apollo 13 ill-fated space mission launched * April 17 – Apollo 13 returns safely to Earth * August 17 – Venera program: Venera 7 is launched. It will later becomes the first spacecraft to successfully transmit data from another planet. * November 17 – Luna program: The Soviet Union lands Lunokhod 1 on Mare Imbrium (Sea of Rains) on the Moon. This is the first roving remote-controlled robot to land on another world and was released by the orbiting Luna 17 spacecraft. Biology * Establishment of Parc naturel régional de Camargue in the south of France. Chemistry * August – Ulrich K. Laemmli publishes his refinement of the SDS-PAGE method. Computer science * January 1 – Unix time begins at 0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
