SPACE-AGETECHNOLOGY

Food Production

Technological innovation in food production was evidenced by irradiation technique, a treatment by electromagnetic rays, and accelerated freeze drying to reserve foods. There was increased mechanism of farming with the widespread use of pesticides and herbicides.

Scientific farming with careful breeding controlled feeding and mechanized handling techniques were also learned. Aquaculture for farming the sea and the seabed, and hydroponics for food production without using soil is being booked into the world’s food so as to increase supply.

CIVIL ENGINEERING

New engineering techniques have not influenced the construction industry, since manual labor was still needed. However, in 1945, the heavy bulldozer and tower crane becomes important new equipment. Home systems like as plumbing and heating food that had begun before World War II continued progressing with a proliferation of electrical equipment.

TRANSPORTATION

Transport development was seen in the early 20th century. The automobile grew in popularity, causing changes in life patterns. Air transport flourished after World War II with direct passenger flights across the Atlantic. The first airliners were those developed from war experience from Douglas DC-3 in the 1930s. the 1950s witnessed the coming of big jet-powered civil airliners.

Vertical takeoff and landing techniques of an aircraft were successfully pioneered by a British military airplane, the Hawker Siddely Harrier. Air cushion vehicles were developed from the Hovercraft, one of the most outstanding technological innovations of 1945. Its main feature is a downblast or air creating an air cushion which the craft rides without direct contact with the sea or the ground below it.

For nearly 30 years, a supersonic flight which is an exclusive military and research aircraft was realized commercially in 1975. This is the Soviet Tu-144 cargo plane in 1976. Regular passemger service was rendered by the Concorde Supersonic Transport(SSST), a joint project of the British and French governments.

COMMUNICATIONS

Fast development was seen in the growth of television services that influenced media and mass communications in the 1920s and 1930s.

RADARS • commonly used on ships, airplanes, and in military stations to give early warning signal against aerial or sea attacks.

transistor• for

computers, control engineering, and communication techniques.

Space satelliteswas developed in the 1960s for telephone communication as well as relaying meteorological photos and data.

Magnetic tapea means of

recording sound and vision.

Printing techniquePHOTOTYPE

conventional metal type replaced by photographic image.

XEROGRAPHY

dry copying process; ink powder attracted to image to be copied by static electricity and fused by heating.

OPTICAL DEVICESzoom lenses with increased power of camera and improved film in cinema and television.

LASER TECHNIQUELight Amplification by Stimulated Emission of Radiation is a powerful means of communication by long distance. It is also used in surgical techniques.

ELECTROMAGNETIC WAVES

used instead of light to venture into the structure of the universe by radio telescope and x-ray telescope.

RADIO TELESCOPE have been directed towards the sun’s closest neighbors with the hope of receiving electromagnetic signals from other species in the universe.
