Finally elementary particles are protons, electrons, neutrons and all other particles that are smaller than an atom.

Quarks and gluons are the fundamental building blocks of protons and neutrons -- elementary particles that combined to forge the basic elements of the periodic table.

Wigner realized that using principles derived from Albert Einstein's theory of relativity, he could describe all the possible elementary particles in the universe, even those that hadn't been discovered yet.

One of the best known is radioactive decay: a process where due to quantum effects, elementary particles can escape the attractive force that ties them to atomic nuclei.

Panpsychism may remain a controversial theory in science that contends that consciousness extends to everything in the universe down to the smallest elementary particle, but Pollini’s playing has something to say about it.
