Antoine Magnan
Antoine Magnan (13 June 1881 – 5 March 1938) was a French zoologist and aeronautical engineer who studied the flight of insects and birds for possible lessons to apply to powered flight. He is best known for a remark in his 1934 book ''Le Vol des Insectes'' ("Insect Flight") that insect flight was impossible. Life and work Magnan was born in the central 7th arrondissement of Paris on 13 June 1881. He qualified as a doctor of medicine and of science, and received the diploma of superior studies in zoology. He became a professor of animal mechanics applied to aviation at the Collège de France (from 1929 to 1938), and the director of the experimental morphology laboratory and the aviation laboratory at the École pratique des hautes études in Paris. He was responsible to the ministries of Education, Agriculture and the Interior.

Zoologist
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the Animal, animal kingdom, including the anatomy, structure, embryology, evolution, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bumblebee
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are social insects that form colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Cuckoo bumblebees are brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumblebee species, kill the resident queen ...

André Sainte-Laguë
André Sainte-Laguë (, 20 April 1882 – 18 January 1950) was a French mathematician who was a pioneer in the area of graph theory. His research on seat allocation methods (published in 1910) led to one being named after him, the Sainte-Laguë method. Also named after him is the Sainte-Laguë Index for measuring the proportionality of an electoral outcome. He is also notable for his informal calculation that supposedly demonstrated that a bumblebee could not fly, referred to in the introduction of 'Le Vol des Insectes' (Hermann and Cle, Paris, 1934) by the entomologist Antoine Magnan. This casual calculation was based on a comparison between an aeroplane and a bee, making the wrong assumption that bees' wings were smooth and flat. He, and others, soon corrected this assumption, but the story of the scientist who demonstrated that bee flight was impossible persists to this day.

Aeronautical Engineer
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, Air propulsion, avionics, materials science, stru ...

It does not grant degrees. Each professor is required to give lectures where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviation
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...
