All these constructions and the laws connecting them can be arrived at by the principle of looking for the mathematically simplest concepts and the link between them.
There are times when one feels liberated from one’s limits and human imperfections. At such moments, we see ourselves there, in a little corner of our little planet, our eyes fixed in wonder on the cold and yet deep beauty of that which is eternal, that which is elusive. Life and death are fused together and there is no evolution, nor destination, there is only BEING.
Nothing that I can do or say will change the structure of the universe. But maybe, by raising my voice, I can help the greatest of all causes — good will among men and peace on earth.
From a certain temperature on, the molecules 'condense' without attractive forces; that is, they accumulate at zero velocity. The theory is pretty, but is there some truth in it.
All conditions and all circumstances in our lives are a result of a certain level of thinking. If we want to change the conditions and circumstances, we have to change the level of thinking that is responsible for it.
The opinion prevailed among advanced minds that it was time that belief should be replaced increasingly by knowledge; belief that did not itself rest on knowledge was superstition, and as such had to be opposed.
It is my belief that the problem of bringing peace to the world on a supranational basis will be solved only by employing Gandhi's method on a larger scale.
If one holds these high principles clearly before one's eyes, and compares them with the life and spirit of our times, then it appears glaringly that civilized mankind finds itself at present in grave danger. In the totalitarian states it is the rulers themselves who strive actually to destroy that spirit of humanity. In less threatened parts it is nationalism and intolerance, as well as the oppression of the individuals by economic means, which threaten to choke these most precious traditions.
All religions, arts and sciences are branches of the same tree. All these aspirations are directed toward ennobling man's life, lifting it from the sphere of mere physical existence and leading the individual towards freedom.
To sense that behind anything that can be experienced there is a something that our mind cannot grasp and whose beauty and sublimity reaches us only indirectly and as a feeble reflection, this is religiousness. In this sense I am religious.
There lies the weaknesss of positivists and professional atheists who are elated because they feel that they have not only successfully rid the world of gods but "bared the miracles." (That is, explained the miracles. - ed.) Oddly enough, we must be satisfied to acknowledge the "miracle" without there being any legitimate way for us to approach it . I am forced to add that just to keep you from thinking that -weakened by age-I have fallen prey to the clergy.
If one asks the whence derives the authority of fundamental ends, since they cannot be stated and justified merely by reason, one can only answer: they exist in a healthy society as powerful traditions, which act upon the conduct and aspirations and judgments of the individuals; they are there, that is, as something living, without its being necessary to find justification for their existence.
On the left-hand side of the field equation we may add the fundamental tensor guv, multiplied by a universal constant, -λ, at present unknown, without destroying the general covariance.
