Tesla's father, Milutin, was an Orthodox priest inside the village of Smiljan. Tesla afterwards wrote that he turned serious about demonstrations of electricity by his physics professor.[b] Tesla noted that these demonstrations of this "mysterious phenomena" made him want "to understand much more of this fantastic force".
Tesla disagreed with the theory of atoms currently being made up of smaller subatomic particles, stating there was no this sort of issue being an electron creating an electric cost. He thought that if electrons existed at all, they were some fourth state of matter or "sub-atom" that could exist only within an experimental vacuum and which they this site experienced almost nothing to try and do with electric power.
