Quote

A theorist today is hardly considered respectable if he or she has not introduced at least one new particle for which there is no experimental evidence.

More quotes by Steven Weinberg

It is almost irrestible for humans to believe that we have some special relation to the universe, that human life is not just a more-or-less farcical outcome of a chain of accidents reaching back to the first three minutes, but that we were somehow built in from the beginning.
Steven Weinberg
Image
Our mistake is not that we take our theories too seriously, but that we do not take them seriously enough.
Steven Weinberg
Image
The invisible and the non-existent look very much alike.
Steven Weinberg

This doesn't mean that they commit themselves to the view that this is all there is. Many scientists (including me) think that this is the case, but other scientists are religious, and believe that what is observed in nature is at least in part a result of God's will.

In our universe we are tuned into the frequency that corresponds to physical reality. But there are an infinite number of parallel realities coexisting with us in the same room, although we cannot tune into them.

A physicist friend of mine once said that in facing death, he drew some consolation from the reflection that he would never again have to look up the word hermeneutics in the dictionary.

The whole history of the last thousands of years has been a history of religious persecutions and wars, pogroms, jihads, crusades. I find it all very regrettable, to say the least.
Steven Weinberg

I can hope that this long sad story, this progression of priests and ministers and rabbis and ulamas and imams and bonzes and bodhisattvas, will come to an end. I hope this is something to which science can contribute ... it may be the most important contribution that we can make.

I think one of the great historical contributions of science is to weaken the hold of religion. That's a good thing.
Steven Weinberg

For good people to do evil things, it takes religion.

My advice is to go for the messes - that's where the action is.

How strange it would be if the final theory were to be discovered in our lifetimes! The discovery of the final laws of nature will mark a discontinuity in human intellectual history, the sharpest that has occurred since the beginning of modern science in the seventeenth century. Can we now imagine what that would be like?
Steven Weinberg

There is now a feeling that the pieces of physics are falling into place, not because of any single revolutionary idea or because of the efforts of any one physicist, but because of a flowering of many seeds of theory, most of them planted long ago.

It seems a bit unfair to my relatives to be murdered in order to provide an opportunity for free will for Germans, but even putting that aside, how does free will account for cancer? Is it an opportunity of free will for tumors?

As for me, I have just enough confidence about the multiverse to bet the lives of both Andrei Linde and Martin Rees’s dog.

It appears that anything you say about the way that theory and experiment may interact is likely to be correct, and anything you say about the way that theory and experiment must interact is likely to be wrong.

If history is any guide at all, it seems to me to suggest that there is a final theory. In this century we have seen a convergence of the arrows of explanation, like the convergence of meridians toward the North Pole.

The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy.
Steven Weinberg
Image
If there is a God that has special plans for humans, then He has taken very great pains to hide His concern for us. To me it would seem impolite if not impious to bother such a God with our prayers.

In complexity, it is only simplicity that can be interesting.
