Japanese engineer Kenjiro Takayanagi was the first to transmit human faces in half-tones on television, influencing the later work of Vladimir K. Zworykin [18] 1928: First experimental Television broadcast in the U.S. 1929: First public TV broadcast in Germany 1931: First wind energy plant in the Soviet Union 1934
The earliest evidence of water wheels and watermills date back to the ancient Near East in the 4th century BC, [27] specifically in the Persian Empire before 350 BC, in the regions of Mesopotamia (Iraq) and Persia (Iran). [28] This pioneering use of water power constituted the first human-devised motive force not to rely on muscle power ...
So the earliest evidence of tool use that we are likely to find are often cut marks made on bone by stone or shell tools. Therefore, it should not be assumed that the items on this list represent the earliest uses of tools in each area, but rather the earliest uses of tools that have been found .
The earliest pipes were made of clay, and are found at the Temple of Bel at Nippur in Babylonia. [127] [b] 4000 BC: Oldest evidence of locks, the earliest example discovered in the ruins of Nineveh, the capital of ancient Assyria. [130] 4000 BC – 3400 BC: Oldest evidence of wheels, found in the countries of Ukraine, Poland, and Germany. [131 ...
Lev Sergeyevich Termen [a] (27 August [O.S. 15 August] 1896 – 3 November 1993), better known as Leon Theremin was a Russian inventor, most famous for his invention of the theremin, one of the first electronic musical instruments and the first to be mass-produced. He also worked on early television research.
The electroscope was the first electrical measuring instrument. The first electroscope was a pivoted needle (called the versorium ), invented by British physician William Gilbert around 1600. [ 1 ] [ 2 ] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope [ 2 ] that are still used in physics ...
A music sequencer, a programmable musical instrument, was the earliest type of programmable machine. The first music sequencer was an automated flute player invented by the Banu Musa brothers, described in their Book of Ingenious Devices, in the 9th century. [38] [39] In 1206, Al-Jazari invented programmable automata/robots.
The MOSFET made it possible to build high-density integrated circuit chips. [30] The earliest experimental MOS IC chip to be fabricated was built by Fred Heiman and Steven Hofstein at RCA Laboratories in 1962. [35] MOS technology enabled Moore's law, the doubling of transistors on an IC chip every two years, predicted by Gordon Moore in 1965. [36]
