12:30 AM In 1907 Nikola Tesla wrote this: "The primary substance [AEther], thrown into infinitesimal whirls of prodigious velocity, becomes gross matter".

Electrons were first discovered in 1897 or ten years earlier and were thought to be particles thus matter but the charge to mass ratio than mass was first calculated in 1909.

According to AEther whirls theory, electrons are autonomous independent whirls (though they can merge in greater whirls) like lobes around centers. 

Protons were discovered ten years later, in 1917.

Tesla always claimed he was in contact with aliens. That, i believe.

I think this is the only way he could have known, years before the discovery of protons or Bohr's model or lobe model or string theory or AEther whirls theory.

Or maybe, since he mentions things like Ākāśa or Prana, he had access to more complete Sanskrit texts other than hRdaya sUtra.

Most likely coming from a previous human civilization that existed and was wiped out by the last ice age (with the surviving part, Egypt). More scientific then technological, which used pyramids as stargates and sources of power.

Tesla wanted to harness the unlimited energy of AEther using oscillating circuits. But i think he might have confused the source of energy with Earth's electric field gradient. Using that on planetary scale would have meant depletion of ionosphere.
