Schematic representation of a Nipkow disk

The ability to scan images point by line and line-by-line and to transmit the brightness values ​​electrically, as well as the benefits of such a technique Alexander Bain pointed out in 1843. The first useful realization invented in 1883 Paul Nipkow. His electric telescope, which with the help of a rotating disc (Nipkow disc), which was provided with spirally arranged holes, decomposed or reassembled images into light-dark signals, he applied for a patent on January 6, 1884. According to the ideas of Paul Nipkow reach the beginning of the 20th century, the first television picture transmissions. Paul Nipkow is therefore referred to as the inventor of the first practical realization of television.

However, Nipkow himself never realized his idea; at that time there was still no suitable way of amplifying it, and the then only known light-sensitive cell, the selenium cell, was too slow for television broadcasts.

At the 2nd place is The Big Bang theory I like it because it reflects my life with friends too I am Sheldon the others I do not say they want to remain anonymous. Otherwise, Elementary likes to watch. It is also a Sherlock Holmes series simply the consequences are Shorter the cases the build up and so is different. But it's about the same. That's what I watch on TV
