Rutherford thanks to path breaking experiments of Geiger and Marsden came to the conclusion that atom consisted of a central small massive nucleus with a positive charge surrounded by a much larger cloud of negatively charged electrons.
But one disparity was nagging him.
There was a mismatch between the atomic number/number of positive charges in the nucleus with the mass of the nucleus they were getting in their experiments.
How to explain this?
For this he proposed that besides the normal protons in the nucleus there were other neutralized protons in the nucleus.
There neutralized protons were neutralized by closely bounded electrons WITHIN the nucleus.
This theory could also explain the phenomenon of beta radiation which is emission of electrons from the nucleus of the atom.
Hence throughout the 1920s, the physicists assumed that the nucleus of an atom consisted of protons and "nuclear electrons".
I know, with the benefit of hindsight, it appears laughable.
But the whole point of my narratives is to show you mon ami, how scientific knowledge accrues.
At that time a very very strange Englishman by the name of Paul Dirac formulated an astounding equation.
His equation describes the behavior of elementary particles called fermions (quarks and leptons).
Just for your information, the term fermion was coined by Paul Dirac after another genius Enrico Fermi.
He was modest enough not to have named fermion as Diracle or Diracion which he could well have as he was the supreme Englishman at the era when the British Empire still reigned supreme.
The Dirac equation also implied or predicted the existence of antimatter, theoretical physics at its best.
Along with this, another set of interesting data was coming in from the Nazi Germany from experiments being conducted by Walther Bothe.
Note that the United States even as late as 1930s was nowhere close to Europe as far as particle physics were concerned.
They were more concerned pragmatically with "useful" stuff such as electricity, wireless telegraphy and communication.
South Asia of course was more busy on deciding how the Hindus, Muslims and different castes needed to be segregated.
We shall continue this interesting tale in the nights to come.

Good night mon ami and my fellow cousin ape.
