My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.

Very much, string theory is simply a work in progress. What we are inching toward every day are predictions that within the realm of current technology we hope to test. It's not like we're working on a theory that is permanently beyond experiment. That would be philosophy.
Interpretation
String theory is an evolving idea in physics that aims to be testable with current technology.
In this quote, Brian Greene emphasizes that string theory, while still developing, is grounded in scientific inquiry that aspires to yield experimental predictions. He contrasts it with philosophical theories, suggesting that scientific theories like string theory should ultimately be subject to empirical testing, reflecting the dynamic nature of scientific exploration.
In practice
In a lecture on scientific advancements where theories are discussed.
My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.
All 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.
Ants make up two-thirds of the biomass of all the insects. There are millions of species of organisms and we know almost nothing about them.
One of the pleasures of looking at the world through mathematical eyes is that you can see certain patterns that would otherwise be hidden.
If a sect does officially insist that its structure of belief demands that evolution be false, then no compromise is possible. An honest and competent biology teacher can only conclude that the sect's beliefs are wrong and that its religion is a false one.
In no other branch of mathematics is it so easy for experts to blunder as in probability theory.
We and other groups are seeing clear statistical links between telomere shortness and risk for a variety of diseases that are becoming very common, such as cardiovascular disease, diabetes and certain cancers.
Global warming is controversial, of course, but the controversy is mainly over whether human activity is driving it.
