In this 21st century, every day we are dealing with the electronic circuits and devices in some or the other forms.
Why do we need to know about the past of electronics development?

Task 1. Read and translate the text. An English physicist W. Gilbert proposed the term “electricity” as far back as 1700. A major electronic development occurred in about 1819 when H. Oersted, a Danish physicist, found the correlation between an electric and a magnetic field. In 1831 M. Faraday opened the electromagnetic induction phenomenon. In 1853, an American painter S. Morse built a telegraph with the original coding system and W. Thomson, a Scottish physicist and mathematician, implemented a digital-to-analog converter using resistors and relays. In 1866, D. Kaselly, an Italian physicist, invented a pan telegraph that became a prototype of the fax. A.G. Bell’s invention of the telephone in 1875 was the most significant event in the entire history of communication. A. Popov and G. Marconi demonstrated their first radio transmitting and receiving systems in 1895-1897.
Task 3. Translate the following verbs. to propose – to occur – to find, found, found – to open – to build, built, built – to implement – to invent – to demonstrate -
