THE ORIGIN OF THE UNIVERSE 1

I must not offend religious sensibilities, even Viking religious sensibilities, but I think it is fair to say that this is not a very satisfying picture of the origin of the universe.

THE STRUCTURE OF SPACE ACCORDING TO THE GENERAL THEORY OF RELATIVITY

But it is conceivable that our universe differs only slightly from a Euclidean one, and this notion seems all the more probable, since calculations show that the metrics of surrounding space is influenced only to …

EUCLIDEAN AND NON-EUCLIDEAN CONTINUUM

It is a veritable wonder that we can carry our this business without getting into the greatest difficulties. We only need to think of the following. If at any moment three squares meet at a …

BEHAVIOR OF CLOCKS AND MEASURING RODS ON A ROTATING BODY OF REFERENCE

The observer performs experiments on his circular disc with clocks and measuring-rods. In doing so, it is his intention to arrive at exact definitions for the signification of time- and space-data with reference to the …

A FEW INFERENCES FROM THE GENERAL PRINCIPLE OF RELATIVITY

Should we be justified in saying that for this reason electrostatics is overthrown by the field-equations of Maxwell in electrodynamics? Not in the least. Electrostatics is contained in electrodynamics as a limiting case; the laws …

IN WHAT RESPECTS ARE THE FOUNDATIONS OF CLASSICAL MECHANICS AND OF THE SPECIAL THEORY OF RELATIVITY UNSATISFACTORY?

The objection is of importance more especially when the state of motion of the reference body is of such a nature that it does not require any external agency for its maintenance, e.g. in the …

THE EQUALITY OF INERTIAL AND GRAVITATIONAL MASS AS AN ARGUMENT FOR THE GENERAL POSTULATE OF RELATIVITY

Relying on his knowledge of the gravitational field (as it was discussed in the preceding section), the man in the chest will thus come to the conclusion that he and the chest are in a …

GRAVITATIONAL FIELD

If now, as we find from experience, the acceleration is to be independent of the nature and the condition of the body and always the same for a given gravitational field, then the ratio of …

SPECIAL AND GENERAL PRINCIPLE OF RELATIVITY

Since the introduction of the special principle of relativity has been justified, every intellect which strives after generalization must feel the temptation to venture the step towards the general principle of relativity.

MINKOWSKI’S FOUR-DIMENSIONAL SPACE

The four-dimensional mode of consideration of the “world” is natural on the theory of relativity, since according to this theory time is robbed of its independence. Moreover, according to this equation the time difference ∆t' …

THE RELATIVITY OF SIMULTANEITY

Events which are simultaneous with reference to the embankment are not simultaneous with respect to the train, and vice versa (relativity of simultaneity). Every reference-body (co-ordinate system) has its own particular time; unless we are …

After some time perhaps the following answer would occur to you: “The significance of the statement is clear in itself and needs no further explanation; of course it would require some consideration if I were …

Vulnerability is the essence of romance. It’s the art of being uncalculated, the willingness to look foolish, the courage to say, ‘This is me, and I’m interested in you enough to show you my flaws with the hope that you may embrace me for all that I am but, more important, all that I am not.’
