Plessey, the British electronics company, formed a new subsidiary known as Tellurometer (Pty) Limited in the 1960s to manufacture the product and to develop and sell derivatives. [5] The company subsequently introduced numerical displays, solid state transmitters, integrated circuits and eventually microprocessors for the product.
The Great Rift Valley of Africa provides critical evidence for the evolution of early hominins.The earliest tools in the world can be found there as well: An unidentified hominin, possibly Australopithecus afarensis or Kenyanthropus platyops, created stone tools dating to 3.3 million years ago at Lomekwi in the Turkana Basin, eastern Africa.
First public television broadcasts in the UK by John Logie Baird between London and Glasgow and in the US by Frederic Eugene Ives (1882–1953) between Washington and New York. The American inventor Philo Taylor Farnsworth (1906–1971) developed in Los Angeles, the first fully electronic television system in the world.
Millimetre wave communication was first investigated by Bengali physicist Jagadish Chandra Bose during 1894–1896, when he reached an extremely high frequency of up to 60 GHz in his experiments. [25] He also introduced the use of semiconductor junctions to detect radio waves, [26] when he patented the radio crystal detector in 1901. [27] [28]

Robert Moog, inventor of the Moog synthesizer. An electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry.Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener.
It is the earliest known electric-powered musical instrument, antedated only by the Denis d'or, which is only known from written accounts.
