Waldo (short Story)
"Waldo" (1942) is a short story by American writer Robert A. Heinlein, originally published in ''Astounding Magazine'' in August 1942 under the pseudonym Anson MacDonald. It is available in the 1950 book ''Waldo & Magic, Inc.'' (as well as other collections). Both stories in that collection involve magic but are otherwise unrelated. The essence of the story is the journey of a mechanical genius from his self-imposed exile from the rest of humanity to a more normal life, conquering the disease myasthenia gravis as well as his own contempt for humans in general. The key to this is that magic is loose in the world, but in a logical and scientific way. Waldo Farthingwaite-Jones was born a weakling, unable even to lift his head up to drink or to hold a spoon. Far from destroying him, this channeled his intellect, and his family's money, into the development of the device patented as "Waldo F. Jones' Synchronous Reduplicating Pantograph". Wearing a glove and harness, Waldo could co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert A
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Space Station
A space station is a spacecraft capable of supporting a human crew in orbit for an extended period of time, and is therefore a type of space habitat. It lacks major propulsion or landing systems. An orbital station or an orbital space station is an artificial satellite (i.e. a type of orbital spaceflight). Stations must have docking ports to allow other spacecraft to dock to transfer crew and supplies. The purpose of maintaining an orbital outpost varies depending on the program. Space stations have most often been launched for scientific purposes, but military launches have also occurred. Space stations have harboured so far the only long-duration direct human presence in space. After the first station Salyut 1 (1971) and its tragic Soyuz 11 crew, space stations have been operated consecutively since Skylab (1973), having allowed a progression of long-duration direct human presence in space. Stations have been occupied by consecutive crews since 1987 with the Salyut successor M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Purpose Dexterous Manipulator
Dextre, also known as the Special Purpose Dexterous Manipulator (SPDM), is a two armed robot, or telemanipulator, which is part of the Mobile Servicing System on the International Space Station (ISS), and does repairs that would otherwise require astronauts to do spacewalks. It was launched on March 11th, 2008 on the mission STS-123. Dextre is a small part of Canada's contributions to the ISS and was named to represent its dexterous nature. Dextre is the newest of three Canadian robotic arm used on the ISS, preceded by the Space Shuttle's Canadarm and the large Canadarm2. Dextre was designed and manufactured by MDA.CanWest News Service'"Canada Hand" successfully installed', 15 March 2006 In the early morning of February 4, 2011, Dextre completed its first official assignment which consisted of unpacking two pieces for Kounotori 2 while the on-board crew was sleeping.

Canadarm
Canadarm or Canadarm1 (officially Shuttle Remote Manipulator System or SRMS, also SSRMS) is a series of robotic arms that were used on the Space Shuttle orbiters to deploy, manoeuvre, and capture payloads. After the Space Shuttle ''Columbia'' disaster, the Canadarm was always paired with the Orbiter Boom Sensor System (OBSS), which was used to inspect the exterior of the shuttle for damage to the thermal protection system. Development In 1969, Canada was invited by the National Aeronautics and Space Administration (NASA) to participate in the Space Shuttle program. At the time what that participation would entail had not yet been decided but a manipulator system was identified as an important component. Canadian company DSMA ATCON had developed a robot to load fuel into CANDU nuclear reactors; this robot attracted NASA's attention. In 1975, NASA and the Canadian National Research Council (NRC) signed a memorandum of understanding that Canada would develop and construc ...

Free Silver
Free silver was a major economic policy issue in the United States in the late 19th-century. Its advocates were in favor of an expansionary monetary policy featuring the unlimited coinage of silver into money on-demand, as opposed to strict adherence to the more carefully fixed money supply implicit in the gold standard. Free silver became increasingly associated with populism, unions, and the fight of ordinary Americans against the bankers and monopolists, and the robber baron (industrialist), robber barons of the Gilded Age capitalism era and was referred to as the "People's Money". Supporters of an important place for silver in a bimetallism, bimetallic money system making use of both silver and gold, called "Silverites", sought coinage of silver dollars at a fixed weight ratio of 16-to-1 against dollar coins made of gold. Because the actual price ratio of the two metals was substantially higher in favor of gold at the time, most economists warned that the less valuable silver ...

Campaign Button
A campaign button is a pin used during an election as political advertising for (or against) a candidate or political party, or to proclaim the issues that are part of the political platform. In the United States, political buttons date as far back as President George Washington. They have taken many forms as the technology to create an image and mass production has allowed. In the late 18th and first half of the 19th century they were sewn-on clothing buttons, whereas the modern forms typically have pins on the back and are therefore also called pin-back buttons. Campaign buttons bear some similarity to bumper stickers, which are also used for political and other promotional messages. As a novelty item, campaign buttons are part of the hobby of collecting. History The first photographic image on pins dates to 1860. Abraham Lincoln and his various opponents used the tintype or ferrotype photo process. The first mass production of metal buttons dates to the 1896 William McKinley ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astounding Science Fiction
''Analog Science Fiction and Fact'' is an American science fiction magazine published under various titles since 1930. Originally titled ''Astounding Stories of Super-Science'', the first issue was dated January 1930, published by William Clayton, and edited by Harry Bates. Clayton went bankrupt in 1933 and the magazine was sold to Street & Smith. The new editor was F. Orlin Tremaine, who soon made ''Astounding'' the leading magazine in the nascent pulp science fiction field, publishing well-regarded stories such as Jack Williamson's '' Legion of Space'' and John W. Campbell's "Twilight". At the end of 1937, Campbell took over editorial duties under Tremaine's supervision, and the following year Tremaine was let go, giving Campbell more independence. Over the next few years Campbell published many stories that became classics in the field, including Isaac Asimov's ''Foundation'' series, A. E. van Vogt's ''Slan'', and several novels and stories by Robert A. Heinl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Attack
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to the coronary artery of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw. Often it occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat or feeling tired. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest. Most MIs occur due to coronary artery disease. Risk factors include high blood pressure, smoking, diabetes, lack of e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rube Goldberg
Reuben Garrett Lucius Goldberg (July 4, 1883 – December 7, 1970), known best as Rube Goldberg, was an American cartoonist, sculptor, author, engineer, and inventor. Goldberg is best known for his popular cartoons depicting complicated gadgets performing simple tasks in indirect, convoluted ways. The cartoons led to the expression "Rube Goldberg machines" to describe similar gadgets and processes. Goldberg received many honors in his lifetime, including a Pulitzer Prize for political cartooning in 1948, the National Cartoonists Society's Gold T-Square Award in 1955, and the Banshees' Silver Lady Award in 1959. He was a founding member and first president of the National Cartoonists Society, which hosts the annual Reuben Award, honoring the top cartoonist of the year and named after Goldberg, who won the award in 1967. He is the inspiration for international competitions known as Rube Goldberg Machine Contests, which challenge participants to create a complicated machine to ...

Waterbed
A waterbed, water mattress, or flotation mattress is a bed or mattress filled with water. Waterbeds intended for medical therapies appear in various reports through the 19th century. The modern version, invented in San Francisco and patented in 1971, became a popular consumer item in the United States through the 1980s with up to 20% of the market in 1986 and 22% in 1987. By 2013, they accounted for less than 5% of new bed sales. Construction Waterbeds primarily consist of two types, hard-sided beds and soft-sided beds. A hard-sided waterbed consists of a water-containing mattress inside a rectangular frame of wood resting on a plywood deck that sits on a platform. A soft-sided waterbed consists of a water-containing mattress inside of a rectangular frame of sturdy foam, zippered inside a fabric casing, which sits on a platform. It looks like a conventional bed and is designed to fit existing bedroom furniture. The platform usually looks like a conventional foundation or box ...

Folk Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) comprises medical aspects of traditional knowledge that developed over generations within the folk beliefs of various societies, including indigenous peoples, before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness". Traditional medicine is often contrasted with scientific medicine. In some Asian and African countries, up to 80% of the population relies on traditional medicine for their primary health care needs. When adopted outside its traditional culture, traditional medicine is often considered a form of alternative medicine. Practices known as traditional medicines ...
