My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.
Quantum mechanics broke the mold of the previous framework, classical mechanics, by establishing that the predictions of science are necessarily probabilistic.
Interpretation
What this quote means
Quantum mechanics introduced a new way of understanding the natural world that contrasts with classical mechanics, highlighting uncertainty in predictions.
This quote by Brian Greene emphasizes the revolutionary shift brought about by quantum mechanics in the field of physics. Unlike classical mechanics, which depended on deterministic predictions about physical systems, quantum mechanics reveals that nature is fundamentally probabilistic, meaning that outcomes cannot be precisely determined but are instead described in terms of likelihoods. This change not only transformed scientific thought but also deepened our understanding of the underlying principles governing the universe.

According to inflation, the more than 100 billion galaxies, sparkling throughout space like heavenly diamonds, are nothing but quantum mechanics writ large across the sky. To me, this realization is one of the greatest wonders of the modern scientific age.
So: if you buy the notion that reality consists of the things in your freeze-frame mental image right now, and if you agree that your now is no more valid than the now of someone located far away in space who can move freely, then reality encompasses all of the events in spacetime.
Black holes, we all know, are these regions where if an object falls in, it can't get out, but the puzzle that many struggled with over the decades is, what happens to the information that an object contains when it falls into a black hole. Is it simply lost?
Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.

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.
The energy produced by the breaking down of the atom is a very poor kind of thing. Anyone who expects a source of power from the transformation of these atoms is talking moonshine.
Human societies vary in lots of independent factors affecting their openness to innovation.
Interestingly enough, not all feelings result from the body's reaction to external stimuli. Sometimes changes are purely simulated in the brain maps.
A great deal of my work is just playing with equations and seeing what they give.
There are a number of attributes of species and populations that are not of any particular selective advantage to any single individual in a population but that are of great advantage to the population as a whole.
