Tesla's father, Milutin, was an Orthodox priest while in the village of Smiljan. Tesla later on wrote that he grew to become keen on demonstrations of energy by his physics professor.[b] Tesla pointed out that these demonstrations of the "mysterious phenomena" built him want "to know more of this wonderful force".

Tesla disagreed with the theory of atoms becoming composed of smaller subatomic site particles, stating there was no this kind of factor as an electron making an electric charge. He thought that if electrons existed at all, they were being some fourth point out of make any difference or "sub-atom" which could exist only within an experimental vacuum and which they experienced practically nothing to perform with electrical power.
