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.
Let's not spend resources that we don't need to be sending astronauts back to the moon. Let's not spend expensive resources on bringing people who have reached Mars back again. Prepare them to become a growing colony.
Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of invention. ... [Do not] share the opinion of those narrow minds who disdain everything in science which has not an immediate application. ... A theoretical discovery has but the merit of its existence: it awakens hope, and that is all. But let it be cultivated, let it grow, and you will see what it will become.
It has been a bitter mortification for me to digest the conclusion that the "race is for the strong" and that I shall probably do little more but be content to admire the strides others made in science.
Kidney transplants seem so routine now. But the first one was like Lindbergh's flight across the ocean.
For Dawkins, evolution is a battle among genes, each seeking to make more copies of itself. Bodies are merely the places where genes aggregate for a time.
I'm proud of the fact that I thought of the solar wind. It was an exercise in pursuing curiosity, which is the main motivation for studying physics from a personal standpoint.
