Acceptance Quote by Robert Andrews Millikan
“Indeed, nothing more beautifully simplifying has ever happened in the history of science than the whole series of discoveries culminating about 1914 which finally brought practically universal acceptance to the theory that the material world contains but two fundamental entities, namely, positive and negative electrons, exactly alike in charge, but differing widely in mass, the positive electron-now usually called a proton-being 1850 times heavier than the negative, now usually called simply the electron.”
About This Quote
Source Speech: Lecture on atomic theory, 1915
The quote highlights the breakthrough that matter consists of two fundamental particles—electrons and protons—differing mainly in mass while sharing opposite charge.
In simple terms: Matter is made of light electrons and heavy protons with opposite charge.
