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.
When we take a slight survey of the surface of our globe a thousand objects offer themselves which, though long known, yet still demand our curiosity.
Cancer was not disorganized chromosomal chaos. It was organized chromosomal chaos
Astronomers can look back in time. We can look at things as they used to be. We have an idea there was a Big Bang explosion 13.7 billion years ago. We have a story of how galaxies and stars were made. It's an amazing story.
The universe is very big - there's about 100,000 million galaxies in the universe, so that means an awful lot of stars. And some of them, I'm pretty certain, will have planets where there was life, is life, or maybe will be life. I don't believe we're alone.
I don't believe in technological determinism, especially not in biology and medicine. We have strong laws to keep doctors from monkeying around with humans that will remain in place. It's simply not true that everything that is technologically possible gets done.
I tried out various experiments described in treatises on physics and chemistry, and the results were sometimes unexpected. At times, I would be encouraged by a little unhoped-for success; at others, I would be in the deepest despair because of accidents and failures resulting from my inexperience.
