If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.

Just because things get a little dingy at the subatomic level doesn't mean all bets are off.
Interpretation
This quote suggests that despite uncertainty in the micro world of particles, overall understanding remains intact.
Murray Gell-Mann's quote reflects the idea that while the intricacies of quantum mechanics may introduce confusion and complexity at the subatomic level, it does not invalidate the broader principles that govern our understanding of the universe. It highlights the resilience of scientific theories in the face of localized uncertainty.
In practice
In a lecture on quantum physics to illustrate the nature of scientific inquiry.
If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.
Sometimes the probabilities are very close to certainties, but they're never really certainties
If someone says that he can think or talk about quantum physics without becoming dizzy, that shows only that he has not understood anything whatever about it.
What is especially striking and remarkable is that in fundamental physics a beautiful or elegant theory is more likely to be right than a theory that is inelegant.
For many parts of Nature can neither be invented with sufficient subtlety, nor demonstrated with sufficient perspicuity, nor accommodated unto use with sufficient dexterity, without the aid and intervening of the mathematics, of which sort are perspective, music, astronomy, cosmography, architecture, engineery, and divers others.
Anyone who attempts to generate random numbers by deterministic means is, of course, living in a state of sin.
There are many instances in science, where those closest to the intricacies of the subject have a more highly developed sense of its intractability than those at some remove. On the other hand, those at too great a distance may, I am well aware, mistake ignorance for perspective.
I think of the brain as a computational device: It has a bunch of little components that perform calculations on some small aspect of the problem, and another part of the brain has to stitch it all together, like a tapestry or a quilt.
As in nature, all is ebb and tide, all is wave motion, so it seems that in all branches of industry, alternating currents - electric wave motion - will have the sway.
The existence of nuclear weapons presents a clear and present danger to life on Earth.
