“Is numerical equality (forced by the use of specific physical units) the same as conceptual equality? Of course NOT!”

“When we say two bodies 'touch', what we mean (without knowing it) is that both electromagnetic fields are interacting to avoid physical interpenetration and ... that happens well before subatomic particles touch!”

“So strong was the preconception of absolute space and time in the scientific mentality of those days, that Lorentz did not realize the grand transcendence of what he had discovered, and contented himself with remodeling the edifice of Physics -- instead of rebuilding it with a new foundation.”

“The objective and merit of Einstein's theory is to identify those physical magnitudes which are absolute, i.e. common for all Inertial Frames, distinguishing them from those which are a mere perspective, only shared by those observers in repose within a given Inertial Frame.”

“The universal character of the centrifugal forces leaves us impotent as to discern whether what is going on inside the carrousel is because we are rotating with respect to terra firma (remember my eyes are closed), or because – for some unknown reason unrelated to motion – radial gravitational field has temporarily emerged while the carrousel is as in repose as it was before the given impulse. The latter would have certainly been the interpretation adopted by an intelligent being, had s/he been born and grown up inside the carrousel, without any access whatsoever to the exterior world.”

“Teaching the layperson (divulgare) is not distorting (tergiversare) the subject, but educating the public; and it is our duty as scientists to educate without distorting the essence of the scientific knowledge attained by humanity. The future of our society depends upon this premise.”

“The command of our language is crucial to focusing our thoughts and communicating them with precision to others.”
