Jean Piccard
Jean Felix Piccard (January 28, 1884 in Basel, Switzerland – January 28, 1963 in Minneapolis, Minnesota), also known as Jean Piccard, was a Swiss-born American chemist, engineer, professor and high-altitude balloonist. He invented clustered high-altitude balloons, and with his wife Jeannette, the plastic balloon. Piccard's inventions and co-inventions are used in balloon flight, aircraft and spacecraft. Family Piccard and Jeannette Ridlon met at the University of Chicago where he taught and she received her master's degree. They married and had three sons, John, Paul and Donald, and also had foster children. Stratosphere flight Piccard was the co-pilot for his wife Jeannette on the third and final voyage of the ''Century of Progress''. The largest balloon in the world was conceived for him to fly at the World's Fair in 1933 but was flown there by US Navy pilots who were licensed. After this flight he created the liquid oxygen converter when the liquid failed to vapori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeannette Piccard
Jeannette Ridlon Piccard ( ; January 5, 1895 – May 17, 1981) was an American high-altitude balloonist, and in later life an Episcopal priest. She held the women's altitude record for nearly three decades, and according to several contemporaneous accounts was regarded as the first woman in space.Shayler & Moule, pp. 12, 25–26 Piccard was the first licensed female balloon pilot in the U.S., and the first woman to fly to the stratosphere. Accompanied by her husband, Jean—a member of the Piccard family of balloonists and the twin brother of Auguste Piccard—she reached a height of during a record-breaking flight over Lake Erie on October 23, 1934, retaining control of the balloon for the entire flight. After her husband's death in 1963, she worked as a consultant to the director of NASA's Johnson Space Center for several years, talking to the public about NASA's work, and was posthumously inducted into the International Space Hall of Fame in 1998. From the late 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert R
Robert Lee Rayford (February 3, 1953 – May 15, 1969), sometimes identified as Robert R. due to his age, was an American teenager from Missouri who has been suggested to represent the earliest confirmed case of HIV/AIDS in North America. This is based on evidence published in 1988 in which the authors claimed that medical evidence indicated that he was "infected with a virus closely related or identical to human immunodeficiency virus type 1." Rayford died of pneumonia, but his other symptoms baffled the doctors who treated him. A study published in 1988 reported the detection of antibodies against HIV. Results of testing for HIV genetic material were reported at a scientific conference in Australia in 1999. However, the data has never been published in a peer-reviewed medical or scientific journal. No photos of Rayford are known to exist. Background Robert Rayford was born on February 3, 1953, in St. Louis, Missouri. As a single parent, his mother Constance had to rais ...

Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrotechnics
Pyrotechnics is the science and craft of creating fireworks, but also includes safety matches, oxygen candles, Pyrotechnic fastener, explosive bolts (and other fasteners), parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. This trade relies upon self-contained and self-sustained exothermic chemical reactions to make heat, light, gas, smoke and/or sound. The name etymology, comes from the Greek words ''pyr'' (πυρ; 'fire') and ''technikós'' (τεχνικός; 'artistic'). Improper use of pyrotechnics could lead to List of pyrotechnic incidents, pyrotechnic accidents. People responsible for the safe storage, handling, and functioning of pyrotechnic devices are known as pyrotechnicians. Proximate pyrotechnics Explosions, flashes, smoke, flames, fireworks and other pyrotechnic-driven effects used in the entertainment industry are referred to as proximate pyrotechnics. Proximate refers to the pyrotechnic device's location relative to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinitrotoluene
Troponin T (shortened TnT or TropT) is a part of the troponin complex, which are proteins integral to the contraction of skeletal and heart muscles. They are expressed in skeletal and cardiac myocytes. Troponin T binds to tropomyosin and helps position it on actin, and together with the rest of the troponin complex, modulates contraction of striated muscle. The cardiac subtype of troponin T is especially useful in the laboratory diagnosis of heart attack because it is released into the blood-stream when damage to heart muscle occurs. It was discovered by the German physician Hugo A. Katus at the University of Heidelberg, who also developed the troponin T assay. Subtypes * Slow skeletal troponin T1, TNNT1 (19q13.4, ) * Cardiac troponin T2, TNNT2 (1q32, ) * Fast skeletal troponin T3, TNNT3 (11p15.5, ) Reference values The 99th percentile cutoff for cardiac troponin T (cTnT) is 0.01 ng/mL. The reference range for the high sensitivity troponin T is a normal 52 ng/L. Backgr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blasting Cap
A detonator is a device used to make an explosive or explosive device explode. Detonators come in a variety of types, depending on how they are initiated (chemically, mechanically, or electrically) and details of their inner working, which often involve several stages. Types of detonators include non-electric and electric. Non-electric detonators are typically stab or Pyrotechnics, pyrotechnic while electric are typically "hot wire" (low voltage), exploding bridge wire (high voltage) or explosive foil (very high voltage). The original electric detonators invented in 1875 independently by Julius Smith and Perry Gardiner used mercury fulminate as the primary explosive. Around the turn of the century performance was enhanced in the Smith-Gardiner blasting cap by the addition of 10-20% potassium chlorate. This compound was superseded by others: lead azide, lead styphnate, some aluminium, or other materials such as DDNP (diazo dinitro phenol) to reduce the amount of lead emitted in ...

B-26 Marauder
The Martin B-26 Marauder is an American twin-engined medium bomber that saw extensive service during World War II. The B-26 was built at two locations: Baltimore, Maryland, and Omaha, Nebraska, by the Glenn L. Martin Company. First used in the Asiatic-Pacific Theater, Pacific Theater of World War II in early 1942, it was also used in the Mediterranean Theater of Operations, Mediterranean Theater and in Western Front (World War II), Western Europe. After entering service with the United States Army aviation units, the Fixed-wing aircraft, aircraft quickly received the reputation of a ":en:wikt:widow-maker, widowmaker" due to the early models' high accident rate during takeoffs and landings. This was because the Marauder had to be flown at precise airspeeds, particularly on final runway approach or when one engine was out. The unusually high 150 mph (241 km/h) speed on short final runway approach was intimidating to many pilots who were used to much slower approach sp ...

B-24 Liberator
The Consolidated B-24 Liberator is an American heavy bomber, designed by Consolidated Aircraft of San Diego, California. It was known within the company as the Model 32, and some initial production aircraft were laid down as export models designated as various LB-30s, in the Land Bomber design category. At its inception, the B-24 was a modern design featuring a highly efficient shoulder-mounted, high aspect ratio Davis wing. The wing gave the Liberator a high cruise speed, long Range (aeronautics), range and the ability to carry a heavy Aerial bomb, bomb load. In comparison with its contemporaries, the B-24 was relatively difficult to fly and had poor low-speed performance; it also had a lower Ceiling (aeronautics), ceiling and was less robust than the Boeing B-17 Flying Fortress. While Aircrew#Military, aircrews tended to prefer the B-17, General Staff favored the B-24 and procured it in huge numbers for a wide variety of roles. At approximately 18,500 units – including 8,68 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Century Of Progress
A Century of Progress International Exposition, also known as the Chicago World's Fair, was a world's fair held in the city of Chicago, Illinois, United States, from 1933 to 1934. The fair, registered under the Bureau International des Expositions (BIE), celebrated the city's centennial. Designed largely in Art Deco style, the theme of the fair was technological innovation, and its motto was "Science Finds, Industry Applies, Man Conforms", trumpeting the message that science and American life were wedded. Its architectural symbol was the Sky Ride, a transporter bridge perpendicular to the shore on which one could ride from one side of the fair to the other. One description of the fair noted that the world, "then still mired in the malaise of the Great Depression, could glimpse a happier not-too-distant future, all driven by innovation in science and technology". Fair visitors saw the latest wonders in rail travel, automobiles, architecture and even cigarette-smoking robots. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
