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.

All quotes βAll mathematics is is a language that is well tuned, finely honed, to describe patterns; be it patterns in a star, which has five points that are regularly arranged, be it patterns in numbers like 2, 4, 6, 8, 10 that follow very regular progression.

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.

There's something really beautiful about science, that human beings can ask these questions and can answer them. You can make models of nature and understand how it works.

There is no such thing as a special category of science called applied science; there is science and its applications, which are related to one another as the fruit is related to the tree that has borne it.

If a healing technique is demonstrated to have curative properties in properly controlled double-blind trials, it ceases to be alternative. It simply, as Diamond explains, becomes medicine.

I think the reason people are dealing with science less well now than 50 years ago is that it has become so complicated.

To those who ask what the infinitely small quantity in mathematics is, we answer that it is actually zero. Hence there are not so many mysteries hidden in this concept as they are usually believed to be.
