Answer:

Ernest Rutherford.

Explanation:

Ernest Rutherford was a British physicist and one of the greatest experimentalists. He "gave birth" to nuclear physics. He lived from 1871 to 1937.

In 1911, he performed many experiments in order to discover and explore radioactivity. In one of his experiments he discovered that the atom has a positive center charge that contains most of atom's mass. He called that nucleus the proton, after the greek word "protos" which means "first". Different number of protons can be found in the atoms of different elements, which gave their nuclei different charges. That is how he established that the hydrogen nucleus was an elementary particle.

Artyom0805 [142]
 This number would greatly increase, as there are many nations that don't have their own their own country. Some are part of a bigger country (the Tamils in India) and some are distributed among many countries (the Kurds)

Recognizing all those nations could increase some conflicts, such as that between the Kurds and Turkish in Turkey.
I think that a good definition should acknowledge that  some nations have independent states and some are part of another state - the defining characteristics should be a sense of unity among the nation.
