“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.” — Felix Alba-Juez Copy Share Image
“Why is it so difficult for us to think in relative terms? Well, for the good reason that human nature loves absoluteness, and erroneously… — Felix Alba-Juez Copy Share Image
“The past and the future are not a collection of instants shared by all space, but a collection of events that correspond to a… — Felix Alba-Juez Copy Share Image
“The universal character of the centrifugal forces leaves us impotent as to discern whether what is going on inside the carrousel is because we… — Felix Alba-Juez Copy Share Image
“It is curious that the human mind could blindly accept an infinite speed but had reservations to accept a finite one, simply because it… — Felix Alba-Juez Copy Share Image
“The command of our language is crucial to focusing our thoughts and communicating them with precision to others.” — Felix Alba-Juez Copy Share Image
“The existence of both ( electron and pebble ) depends upon the context created by our thoughts, our language, our theories, and our interaction… — Felix Alba-Juez Copy Share Image
“It is worth noting that a wrong folkoric definition of an Inertial Frame in the Popular Science literature (even in text books) reads that… — Felix Alba-Juez Copy Share Image
“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… — Felix Alba-Juez Copy Share Image
“When we say two bodies 'touch', what we mean (without knowing it) is that both electromagnetic fields are interacting to avoid physical interpenetration and… — Felix Alba-Juez Copy Share Image
“So strong was the preconception of absolute space and time in the scientific mentality of those days, that Lorentz did not realize the grand… — Felix Alba-Juez Copy Share Image
“Both space and time are metrically amorphous, i.e. they do not have - despite how strongly we believe so - an inherent metric which… — Felix Alba-Juez Copy Share Image
“Subjectivity is strange to Science, while Relativity is an objective part of it.” — Felix Alba-Juez Copy Share Image
