(1930-) US astronaut. In 1969, he became the first person to set foot on the Moon, and said, “That’s one small step for a man, one giant leap for mankind.” The Moon landing was part of the Apollo project.
Born in Ohio, he gained his pilot's license at 16, and served as a naval pilot in Korea 1949–52 before joining NASA as a test pilot. He was selected to be an astronaut 1962 and landed on the Moon 20 July 1969.

muški rodlično ime

Prevedi Armstrong na: nemački

(1890-1954) US radio engineer who developed a system known as superheterodyne tuning for reception over a very wide spectrum of radio frequencies and frequency modulation (FM) radio transmission for static-free reception.
Armstrong was born and educated in New York, and became a professor at Columbia University. He was involved in much litigation over patents and eventually killed himself.
The superheterodyne receiving circuit was developed by Armstrong during World War I in an attempt to make a receiver that could detect the presence of enemy aircraft by means of the electromagnetic (radio) waves given off by the sparking of the ignition systems of their engines.
At that time, radio broadcasting used amplitude modulation (AM), which is susceptible to static interference. In 1933 Armstrong, with US physicist Michael Pupin (1858–1935), developed and patented the FM method of radio broadcasting, in which the transmitted signal is made to modulate the frequency of the carrier wave over a wide waveband. FM is unaffected by static and is capable of high-fidelity sound reproduction; it remains the basis of quality radio, television, microwave, and satellite transmissions, although the high frequencies used are generally limited to line-of-sight distances. FM broadcasting did not gain ground until after World War II.
