A Quote by Steven Weinberg

Even in the dark times between experimental breakthroughs, there always continues a steady evolution of theoretical ideas, leading almost imperceptibly to changes in previous beliefs.
Because of recent improvements in the accuracy of theoretical predictions based on large scale ab initio quantum mechanical calculations, meaningful comparisons between theoretical and experimental findings have become possible.
Physics has entered a remarkable era. Ideas that were once the realm of science fiction are now entering our theoretical ? and maybe even experimental ? grasp. Brand-new theoretical discoveries about extra dimensions have irreversibly changed how particle physicists, astrophysicists, and cosmologists now think about the world. The sheer number and pace of discoveries tells us that we've most likely only scratched the surface of the wondrous possibilities that lie in store. Ideas have taken on a life of their own.
The University of Cambridge, in accordance with that law of its evolution, by which, while maintaining the strictest continuity between the successive phases of its history, it adapts itself with more or less promptness to the requirements of the times, has lately instituted a course of Experimental Physics.
The success of 'Dhruva' has given me more satisfaction than any of my previous hits, simply because the audience accepted the film even though it was experimental. I really hope this kind of acceptance makes experimental cinema the new mainstream cinema.
There's always a tension in my world between the pragmatic and the practical and the theoretical. I have a very theoretical turn of mind, but I also like to test things in place.
Even though their arguments did not invoke religion, I think we all know what's behind these arguments. They're trying to protect religious beliefs from contradiction by science. They used to do it by prohibiting teachers from teaching evolution at all; then they wanted to teach intelligent design as an alternative theory; now they want the supposed "weaknesses" in evolution pointed out. But it's all the same program - it's all an attempt to let religious ideas determine what is taught in science courses.
The natural evolution of a well-educated populus is integration. And this is not political; it's not theoretical; it's not even partisan.
Love is what carries you, for it is always there, even in the dark, or most in the dark, but shining out at times like gold stitches in a piece of embroidery.
If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to evaluate the experimental material which may lead him to conclusions about the structure of the atom.
The fear of speculation, the ostensible rush from the theoretical to the practical, brings about the same shallowness in action that it does in knowledge. It is by studying a strictly theoretical philosophy that we become most acquainted with Ideas, and only Ideas provide action with vigour and ethical meaning.
No evolution is accomplished in nature without revolution. Periods of very slow changes are succeeded by periods of violent changes. Revolutions are as necessary for evolution as the slow changes which prepare them and succeed them.
I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics.
I love to read and teach experimental fiction but yes, neither this work nor my first novel is really that experimental. It uses some experimental techniques but in the end, I would not say that it is experimental. I'm not sure why. I do a lot of writing on my own, and I have always just written this way.
As the pen rises from the page between words, so the walker's feet rise and fall between paces, and as the deer continues to run as it bounds from the earth and the dolphin continues to swim even as it leaps again and again from the sea, so writing and wayfaring are continuous activities, a running stitch, a persistence of the same seam or stream.
In the experimental sciences, the epochs of the most brilliant progress are almost always separated by long intervals of almost absolute repose.
They're willing to accept changes on the part of the U.S. that contribute to more money entering Cuba so they can benefit. But in terms of political changes on the island, an opening, etc., that won't happen, that won't change, and I've always said that, from the beginning. I've even said that it doesn't matter how many tourists who to Cuba, how many times the President visits Cuba; there won't be any changes in the Cuban government's posture. And that is the same as always.
