Brian Greene Quotes
-
String theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be displaced from ours in some extra dimension of space.
-
Science is a way of life. Science is a perspective. Science is the process that takes us from confusion to understanding in a manner that's precise, predictive and reliable - a transformation, for those lucky enough to experience it, that is empowering and emotional.
-
One of the strangest features of string theory is that it requires more than the three spatial dimensions that we see directly in the world around us. That sounds like science fiction, but it is an indisputable outcome of the mathematics of string theory.
-
For me it's been very exciting to contribute to the public's understanding of how rich and wondrous science is.
-
Exploring the unknown requires tolerating uncertainty.
-
I've seen children's eyes light up when I tell them about black holes and the Big Bang.
-
Writing for the stage is different from writing for a book. You want to write in a way that an actor has material to work with, writing in the first person not the third person, and pulling out the dramatic elements in a bigger way for a stage presentation.
-
Even when I wasn't doing much 'science for the public' stuff, I found that four or five hours of intense work in physics was all my brain could take on a given day.
-
My mom says: 'Why aren't you a doctor?' and I'm like, 'I am a doctor!' and she's all, 'No, I mean a real doctor.' She reads my books, but she says they give her a headache.
-
We are living through a remarkably privileged era, when certain deep truths about the cosmos are still within reach of the human spirit of exploration.
-
I would say in one sentence my goal is to at least be part of the journey to find the unified theory that Einstein himself was really the first to look for.
-
The real question is whether all your pondering and analyses will convince you that life is worth living. That's what it all comes down to.
-
There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.
-
There may be many Big Bangs that happened at various and far-flung locations, each creating its own swelling, spatial expanse, each creating a universe - our universe being the result of only one of those Big Bangs.
-
In any finite region of space, matter can only arrange itself in a finite number of configurations, just as a deck of cards can be arranged in only finitely many different orders. If you shuffle the deck infinitely many times, the card orderings must necessarily repeat.
-
I can't stand clutter. I can't stand piles of stuff. And whenever I see it, I basically just throw the stuff away.
-
I think math is a hugely creative field, because there are some very well-defined operations that you have to work within. You are, in a sense, straightjacketed by the rules of the mathematics. But within that constrained environment, it's up to you what you do with the symbols.
-
Over the centuries, monumental upheavals in science have emerged time and again from following the leads set out by mathematics.
-
I can assure you that no string theorist would be interested in working on string theory if it were somehow permanently beyond testability. That would no longer be doing science.
-
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.
-
Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things.
-
One of the wonders of science is that it is completely universal. It crosses national boundaries with total ease.
-
I think the relationship between memory and time is a very deep and tricky one, to tell you the truth. I don't consider memory another sense. I do consider memory that which allows us to think that time flows.
-
The real reason why general relativity is widely accepted is because it made predictions that were borne out by experimental observations.
