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.

My work shows how important it is that independent researchers should have access to data so that government statistics can be checked and so that the democratic debate within India can be informed by the different interpretations of different scholars.
All of my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them. If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist.
Plasma seems to have the kinds of properties one would like for life. It's somewhat like liquid water--unpredictable and thus able to behave in an enormously complex fashion. It could probably carry as much information as DNA does. It has at least the potential for organizing itself in interesting ways.
The fundamental principle of science, the definition almost, is this: the _x000D_ sole test of the validity of any idea is experiment.
