The three major inventions of World War II: penicillin, the atomic bomb, and radar.
Penicillin is a kind of antimicrobial, a class of antibiotics containing penicillanes in the molecule, which can destroy the cell wall of bacteria and act as a bactericidal agent in the reproduction phase of the bacterial cell, and is an antibiotic extracted from Penicillium.
Penicillin belongs to β-lactam antibiotics (β-lactams), β-lactam antibiotics include penicillin, cephalosporins, carbapenems, monocyclic, cephalosporins and so on. Penicillin is a very common antibacterial drug. However, a skin test must be done before each use to prevent allergies.
Atomic bomb (Atomic bomb) is one of the nuclear weapons, is the use of nuclear reaction of light and heat radiation, shock waves and sense of radioactivity to cause killing and destruction, as well as cause large areas of radioactive contamination, to prevent each other's military action to achieve the strategic purpose of weapons of mass destruction.
Radar, is the English translation of Radar, from the abbreviation of radio detection and ranging, meaning "radio detection and ranging", that is, the use of radio methods to detect the target and determine their spatial position.
Extended information
The Second World War objectively promoted the rapid development of science and technology. During the war, in order to war needs, countries invested a lot of manpower, material and financial resources and the development of science and technology, the manufacture of new weapons, after the Second World War, these scientific and technological used in the manufacture of combat weapons for the cause of peace, and promote the progress of human history and civilization.
The Second World War, as a typical form of war unique to the mechanized era, its military success and failure and the course of the war, depends largely on the internal combustion engine technology as the core of science and technology group and the degree of integration of combat theory and tactics. Before the Second World War, the quiet development of two types of emerging technologies determined the advent of mechanized warfare.
One category was the technology of building airplanes, tanks, and large ships, and the other was electronic communications technology. The extensive and intensive use of tanks and airplanes led the United States, Britain and the Soviet Union to adopt new battle theories and tactics; the United States and Britain began to form battle theories and tactics of air fire support on the ground and intensive use of maneuvering weapons, while the Soviet Army revived the theory of large-depth operations.
