Electronic computer: In order to crack the German code, Britain made the first electronic computer in human history, also called Turing machine. Although it was far from the current computer, it was the latest technology at that time. Later computers were all developed on his basis.

Jet fighter: Germany's Me-262 is the first jet plane in the world, and its appearance announced that the plane entered the jet age.

Swept-wing aircraft: In World War II, German scientists thought that swept-wing aircraft were faster than straight-wing aircraft, and many swept-wing prototypes were produced. After the war, swept-wing aircraft became the mainstream of aircraft design.

Radio walkie-talkie: Many countries used radio walkie-talkies in World War II, which consisted of a microphone and a radio transmitter, but the volume was too large. At the end of World War II, the United States took the lead in using small radios (twice the size of later mobile phones), and continued to simplify them after the war, which is the walkie-talkie in our life now.

Rocket: Germany's V2 rocket is the embryonic form of the current space rocket. This controllable rocket has greatly promoted human exploration of outer space.

Radar and sonar: as search tools for enemy planes and submarines, they were widely used in World War II and continued to develop after the war, still playing an extremely important role.

Atomic bomb: Although its lethality is extremely terrible, it provides people with enormous energy, which is nuclear energy.
