Nikola Tesla was a Serbian –American inventor who was born in 10 July 1856. He studied at Austrian Polytechnic in Graz but, what’s the most interesting, he had never graduated, because on the second year he came into conflict with one of his professors.
Tesla is best known for for his contributions to the design of the modern alternating current and there is an interesting story connected with it. Namely, when Tesla came to the United States in 1884, soon began working with famed inventor Thomas Edison, who was focused on researching direct current in those times. On the other hand, Tesla was a strong follower of alternating current, which was soon improved by Nikola. When Tesla suggested Edison that his power stations ought to have worked on alternating current Edison decided to dismissed him. It was the beginning of huge dispute between them.
Apart from that, Nikola Tesla invented water turbine, radio or remote control and worked on constructing a time machine.
Tesla was a polyglot, he spoke seven languages fluently. Moreover, he had an obsession with the number 3. For instance, the last days of his life he spent in the room number 333 situated on 33 floor.

Nikola Tesla was a Serbian –American inventor 'who was' (niepotr) born in 10 July 1856. He studied at (tu cos brak) Austrian Polytechnic in Graz but, what’s 'the' (niepotr) most interesting (tu cos brak 2 slowa), he 'had' (nie rozumeim uzycia tego slowa tutaj) never graduated, because 'on' (kalka z polskiego - 'na' ale w jez ang to nie jest odpowiednik tego) the second year he came into conflict with one of his professors.
Tesla is best known for 'for' (?) his contributions to the design of the modern alternating current and there is an interesting story connected with 'it' (zle slowo). 'Namely' (niepot), when Tesla came to the United States in 1884, (tu cos brak)( soon began working with (cos brak) 'famed' (zle slowo) inventor Thomas Edison, who was focused on researching 'direct current' ? czego musisz napisac) 'in those times' (niepotr, bo dales dokladny rok). 'On the other hand' (zle - gdzie napisales 'on the one hand' bo tego nie widze), Tesla was a strong follower of alternating current, which was soon improved by 'Nikola' (nazwisko? dlaczego raz piszesz po imieniu a raz po nazwisku?). When Tesla suggested (cos brak) Edison that his power stations ought to have worked on alternating current Edison decided to 'dismissed' (zly czas -) him. It was the beginning of (a gdzie porzedimek? uciekl?) huge dispute between them.
Apart from that, Nikola Tesla invented (cos brak) water turbine, radio 'or' (albo jedno albo drugie?) remote control and worked on constructing a time machine.
For instance, the last days of his life he spent in 'the' (po co to?) room number 333 situated on (cos brak) 33 floor.
