Bat Bomb
Bat bombs were an experimental World War II weapon developed by the United States. The bomb consisted of a bomb-shaped casing with over a thousand compartments, each containing a hibernating Mexican free-tailed bat with a small, timed incendiary bomb attached. Dropped from a bomber at dawn, the casings would deploy a parachute in mid-flight and open to release the bats, which would then disperse and roost in eaves and attics in a . The incendiaries, which were set on timers, would then ignite and start fires in inaccessible places in the largely wood and paper constructions of the Japanese cities that were the weapon's intended target. The United States Navy took control in August 1943, using the code name ProjectX-Ray. Conception The bat bomb was conceived by Lytle S. Adams (1881–1970), a dental surgeon from Irwin, Pennsylvania, who was an acquaintance of First Lady Eleanor Roosevelt. The inspiration for Adams' suggestion was a trip he took to Carlsbad Caverns National ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hibernating
Hibernation is a state of minimal activity and metabolic reduction entered by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and use similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on the sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tim Holt
Charles John "Tim" Holt III (February 5, 1919 – February 15, 1973) was an American actor. He was a popular Western star during the 1940s and early 1950s, appearing in forty-six B westerns released by RKO Pictures. In a career spanning more than four decades, Holt is best remembered for his roles in the films ''The Magnificent Ambersons'' (1942), '' My Darling Clementine'' (1946) and '' The Treasure of the Sierra Madre'' (1948). Early life Holt was born Charles John Holt III on February 5, 1919, in Beverly Hills, California, the son of actor Jack Holt and Margaret Woods. During his early years, he accompanied his father on location, even appearing in an early silent film. He was the inspiration for his father's book, ''Lance and His First Horse''.

Japanese Village (Dugway Proving Ground)
Japanese Village was the nickname for a range of houses constructed in 1943 by the U.S. Army in the Dugway Proving Ground in Utah, roughly southwest of Salt Lake City. History Dugway was a high-security testing facility for chemical and biological weapons. The purpose of the replicas of Japanese homes, which were repeatedly rebuilt after being intentionally burned down, was to perfect the use of incendiary bombing tactics, the fire bombing of Japanese cities during World War II. Testing on the Japanese Village at Dugway Proving Ground coincided with the erosion of precision bombing practice in the U.S. Army Air Force and validated civilians as targets of air warfare during World War II. As such, the interiors of Japanese Village contained furnishing (including tables, futon, radios, chests, hibachi stoves, etc.) as found in contemporaneous Japanese housing. The principal architect for Japanese village was Antonin Raymond who had spent many years building in Japan. Boris La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cellulose
Cellulose is an organic compound with the chemical formula, formula , a polysaccharide consisting of a linear chain of several hundred to many thousands of glycosidic bond, β(1→4) linked glucose, D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant biopolymer, organic polymer on Earth. The cellulose content of cotton fibre is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon. Conversion of cellulose from energy crops into biofuels such as cellulosic ethanol is under development as a renewable fuel source. Cellulose for industrial use is mainly obtained from wood pulp and cotton. Cellulose is also greatly affected by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napalm
Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical (usually gasoline or diesel fuel). The name is a portmanteau of two of the constituents of the original thickening and gelling agents: coprecipitated aluminium salts of ''na''phthenic acid and ''palm''itic acid. A team led by chemist Louis Fieser originally developed napalm for the US Chemical Warfare Service in 1942 in a secret laboratory at Harvard University. Of immediate first interest was its viability as an incendiary device to be used in American fire bombing campaigns during World War II; its potential to be coherently projected into a solid stream that would carry for distance (instead of the bloomy fireball of pure gasoline) resulted in widespread adoption in infantry and tank/boat mounted flamethrowers as well. Napalm burns at temperatures ranging from . It burns longer than gasoline, is more easily dispersed, and adheres to its targets. These traits make it both effective and con ...

Louis Fieser
Louis Frederick Fieser (April 7, 1899 – July 25, 1977) was an American organic chemist, professor, and in 1968, professor emeritus at Harvard University. His award-winning research included work on blood-clotting agents including the first synthesis of vitamin K, synthesis and screening of quinones as malaria, antimalarial drugs, work with steroids leading to the synthesis of cortisone, and study of the nature of polycyclic aromatic hydrocarbons. He also invented militarily effective napalm while at Harvard in 1942. Overview Fieser was born in Columbus, Ohio, obtained his BA in chemistry in 1920 from Williams College, and his PhD under James Bryant Conant at Harvard in 1924. His graduate research concerned the measurement of oxidation potentials in quinone oxidation. Note: nice anecdote in supplementary info in 1924-1925 Fieser worked at the University of Oxford with W.H. Perkin Jr. and with Julius von Braun at the Frankfurt University as a postdoc.

White Phosphorus Munitions
White phosphorus munitions are weapons that use one of the common allotropes of the chemical element phosphorus. White phosphorus is used in smoke, illumination, and incendiary munitions, and is commonly the burning element of tracer ammunition. Other common names for white phosphorus munitions include ''WP'' and the slang terms ''Willie Pete'' and ''Willie Peter'', which are derived from ''William Peter'', the World War II phonetic alphabet rendering of the letters ''WP''. White phosphorus is pyrophoric (it is ignited by contact with air); burns fiercely; and can ignite cloth, fuel, ammunition, and other combustibles. White phosphorus is a highly efficient smoke-producing agent, reacting with air to produce an immediate blanket of phosphorus pentoxide vapour. Smoke-producing white phosphorus munitions are very common, particularly as smoke grenades for infantry, loaded in defensive grenade launchers on tanks and other armoured vehicles, and in the ammunition allotment for a ...
