Radar
Radar is an object-detection system which uses electromagnetic waves—specifically radio waves—to determine the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.

V2 rocket
The V-2 rocket (German: Vergeltungswaffe 2, i.e. retaliation weapon 2), technical name Aggregat-4 (A4), was a ballistic missile that was developed at the beginning of the Second World War in Germany. The liquid-propellant rocket was the world's first long-range[3] combat-ballistic missile[4] and first known non-human-piloted artifact to achieve sub-orbital spaceflight.[5] It was the progenitor of all modern rockets,[6] Wikipedia: V-2 -
Jet Engine
A jet engine is a reaction engine that discharges a fast moving jet to generate thrust by jet propulsion and in accordance with Newton's laws of motion. This broad definition of jet engines includes turbojets, turbofans, rockets, ramjets, pulse jets. In general, most jet engines are internal combustion engines[1] but non-combusting forms also exist.

It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output. Wikipedia: Microprocessor -
Space Shuttle
The Space Shuttle was a manned orbital rocket and spacecraft system operated by NASA on 135 missions from 1981 to 2011. The system combined rocket launch, orbital spacecraft, and re-entry spaceplane with modular add-ons. Major missions included launching numerous satellites and interplanetary probes,[1] conducting space science experiments, and the servicing and construction of space stations. A major international contribution was the Spacelab payload suite, from the ESA. Wikipedia: Space Shutt -
Cell Phones
A mobile phone can make and receive telephone calls to and from the public telephone network which includes other mobiles and fixed-line phones across the world. It does this by connecting to a cellular network provided by a mobile network operator. Wikipedia: Mobile phones -

Hubble Space Telescope
Wikipedia
The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by a Space Shuttle in 1990. It is 2.4 meter (about 8 ft.) aperture telescope in low Earth orbit, observing in the near ultraviolet, visible, and near infrared with four main instruments. Five servicing missions have repaired, upgraded, and replaced systems on the telescope over its lifetime, and it remains in operation as of 2011. -
