If history is any guide at all, it seems to me to suggest that there is a final theory. In this century… — Steven Weinberg Copy Share Image
How then did we come to the "standard model"? And how has it supplanted other theories, like the steady state model? It… — Steven Weinberg Copy Share Image
It was one time when people thought the value of the fine structure constant was important. Now of course it's still important,… — Steven Weinberg Copy Share Image
My work during the 1970s has been mainly concerned with the implications of the unified theory of weak and electromagnetic interactions, with… — Steven Weinberg Copy Share Image
“What one needs is a quantum mechanical model with a wave function that describes not only various systems under study but also… — Steven Weinberg Copy Share Image
“The fact that the force of gravity can be made to disappear for a brief time over a small region around any… — Steven Weinberg Copy Share Image
Even though their arguments did not invoke religion, I think we all know what's behind these arguments. They're trying to protect religious… — Steven Weinberg Copy Share Image
This is often the way it is in physics - our mistake is not that we take our theories too seriously, but… — Steven Weinberg Copy Share Image
I now want to tell three stories about advances in twentieth-century physics. A curious fact emerges in these tales: time and again… — Steven Weinberg Copy Share Image
“In its final form, the general theory of relativity was just a reinterpretation of the existing mathematics of curved spaces in terms… — Steven Weinberg Copy Share Image

This is often the way it is in physics - our mistake is not that we take our theories too seriously, but that we… — Steven Weinberg Copy Share
With or without religion, you would have good people doing good things and evil people doing evil things. But for good people to do… — Steven Weinberg Copy Share
I would say it's a lot easier to develop a decoy system than to develop the intercontinental ballistic missile itself. I would think that… — Steven Weinberg Copy Share
The universe is an enormous direct product of representations of symmetry groups. — Steven Weinberg Copy Share
Its a consequence of the experience of science. As you learn more and more about the universe, you find you can understand more and… — Steven Weinberg Copy Share
Our job in physics is to see things simply, to understand a great many complicated phenomena in a unified way, in terms of a… — Steven Weinberg Copy Share
“Plato and the neo-Platonists taught that the beauty we see in nature is a reflection of the beauty of the ultimate, the nous. For… — Steven Weinberg Copy Share
An expert is a person who avoids the small errors while sweeping on to the grand fallacy. — Steven Weinberg Copy Share
