relativity

A mathematician is an individual who proves his beliefs with equations.

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

A university student attending lectures on general relativity i the morning and others on quantum mechanics in the afternoon might be forgiven for thinking that his professors are fools, or have neglected to communicate with each other for at least a century.

... it should be remembered that the atomicity of electric charge has already found its expression in the specific numerical value of the fine structure constant, a theoretical understanding of which is still missing today.

Here the attention of the research workers is primarily directed to the problem of reconciling the claims of the special relativity theory with those of the quantum theory. The extraordinary advances made in this field by Dirac ... leave open the question whether it will be possible to satisfy the claims of the two theories without at the same time determining the Sommerfeld fine-structure constant.

A relativist is an individual who doesn't know the difference between an adjective and an adverb.

Even when the truth is in fact simple, simplicity is still relative.

Success is a relative thing__nd the victory of a boy at marbles is equal to the victory of an Octavius at Actium when measured by the scale of cosmic infinity.

To lose weight, spend time at the gym. To appear like you__e lost weight, spend time with people who are bigger than you.

With the magnificence of eternity before us, let time, with all its fluctuations, dwindle into its own littleness.

Einstein gave us a problem he knew we would never solve.

Time is only linear for engineers and referees.

Never look directly at the sun. Instead, look at the sunflower.

I am positive that in the vast majority of cases we are hammering nails with microscopes.

If you like it, you'll find a way to justify it.But if you don't , you'll find ways to falsify it.

Einstein, twenty-six years old, only three years away from crude privation, still a patent examiner, published in the Annalen der Physik in 1905 five papers on entirely different subjects. Three of them were among the greatest in the history of physics. One, very simple, gave the quantum explanation of the photoelectric effect__t was this work for which, sixteen years later, he was awarded the Nobel prize. Another dealt with the phenomenon of Brownian motion, the apparently erratic movement of tiny particles suspended in a liquid: Einstein showed that these movements satisfied a clear statistical law. This was like a conjuring trick, easy when explained: before it, decent scientists could still doubt the concrete existence of atoms and molecules: this paper was as near to a direct proof of their concreteness as a theoretician could give. The third paper was the special theory of relativity, which quietly amalgamated space, time, and matter into one fundamental unity. This last paper contains no references and quotes to authority. All of them are written in a style unlike any other theoretical physicist's. They contain very little mathematics. There is a good deal of verbal commentary. The conclusions, the bizarre conclusions, emerge as though with the greatest of ease: the reasoning is unbreakable. It looks as though he had reached the conclusions by pure thought, unaided, without listening to the opinions of others. To a surprisingly large extent, that is precisely what he had done.
