“After some cogitation, it is difficult not to agree with Herman Bondi (1919 - 2005), who in his book 'Relativity and Common Sense' says:... The surprising thing, surely, is that molecules in a gas behave so much as billiard balls, not that electrons behave so little like billiard balls.”

“Why is it so difficult for us to think in relative terms? Well, for the good reason that human nature loves absoluteness, and erroneously considers it as a state of higher knowledge.”

“It is worth noting that a wrong folkoric definition of an Inertial Frame in the Popular Science literature (even in text books) reads that 'it is a frame in uniform motion'. We know very well by now that the idea of motion requires a frame of reference, so that such a definition of an Inertial Frame has no meaning whatsoever, confusing the reader because it tacitly reaffirms the idea of absolute motion -- when the goal of every didactic exposition of Relativity Theory should be precisely the opposite.”

“The notion of Local Inertial Frame is crucial to understanding Nature and, in particular, General Relativity. Notwithstanding, very few popular science books (not even textbooks) emphasize enough its fundamental character.”

“The difference between Lorentz's Transformation in Lorentz's theory and Lorentz's Transformation in Einstein's Special Relativity is not mathematical but ontological and epistemological and, being so, it was to be expected the emergence of historians, scientists, and philosophers that, not having understood in depth the philosophical content and transcendence of the theory, would minimize Einstein's contribution.”

“Einstein's theory, experimentally corroborated for the last hundred years, regardless of how outlandish and opposed to our prejudices (disguised as they are with the 'common sense' costume), is rational, consistent, and intelligible to the layperson - if s/he has the audacity of accepting the unfounded nature of those prejudices.”

“The existence of both (electron and pebble) depends upon the context created by our thoughts, our language, our theories, and our interaction (experimentation) with our external world.”
