Brian Greene Quotes
-
It's hard to teach passionately about something that you don't have a passion for.
→ -
I believe the process of going from confusion to understanding is a precious, even emotional, experience that can be the foundation of self-confidence.
→ -
When I give this talk to a physics audience, I remove the quotes from my 'Theorem'.
→ -
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.
→ -
Time allows change to take place and the very evolution of the universe is what requires some conception of time. Mathematically can we write down a universe that doesn't have time? Sure. Do we think that would be realised in the larger reality that is out there? None of us take that possibility seriously.
→ -
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.
→ -
I'd say many features of string theory don't mesh with what we observe in everyday life.
→ -
...things are the way they are in our universe because if they weren't, we wouldn't be here to notice.
→ -
The main challenge that television presents is that I have a tendency to say things with a great deal of precision and accuracy. Often a description of that sort, which will work in a book because people can read it slowly - they can turn the pages back and so on - doesn't really work on TV because it interrupts the flow of the moving image.
→ -
The pinpoints of starlight we see with the naked eye are photons that have been streaming toward us for a few years or a few thousand.
→ -
I like to think that Einstein would look at string theory’s journey and smile, enjoying the theory’s remarkable geometrical features while feeling kinship with fellow travelers on the long and winding road toward unification.
→ -
Many different planets are many different distances from their host star; we find ourselves at this distance because if we were closer or farther away, the temperature would be hotter or colder, eliminating liquid water, an essential ingredient for our survival.
→ -
Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.
→ -
Free will is the sensation of making a choice. The sensation is real, but the choice seems illusory. Laws of physics determine the future.
→ -
When you drive your car, E = mc2 is at work. As the engine burns gasoline to produce energy in the form of motion, it does so by converting some of the gasoline's mass into energy, in accord with Einstein's formula.
→ -
I believe we owe our young an education that captures the exhilarating drama of science.
→ -
I believe that through its rational evaluation of truth and indifference to personal belief, science transcends religious and political divisions and so does bind us into a greater, more resilient whole.
→ -
Science is the greatest of all adventure stories, one that's been unfolding for thousands of years as we have sought to understand ourselves and our surroundings.
→ -
I’ve spent something like 17 years working on a theory for which there is essentially no direct experimental support.
→ -
But if you think about a practical implication of enriching your life and giving you a sense of being part of a larger cosmos and possibly being able to use this [gravitational waves] as a tool in the future maybe to listen not just to black holes colliding, but maybe listen to the big bang itself, those kind of applications may happen in the not too distant future.
→ -
Falsifiability for a theory is great, but a theory can still be respectable even if it is not falsifiable, as long as it is verifiable.
→ -
We can certainly go further than cats, but why should it be that our brains are somehow so suited to the universe that our brains will be able to understand the deepest workings?
→ -
I was holding [my four-year-old daughter] and I said, 'Sophia, I love you more than anything in the universe.' And she turned to me and said, 'Daddy, universe or multiverse?'
→ -
When kids look up to great scientists the way they do to great musicians and actors, civilization will jump to the next level
→ -
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.
→ -
For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.
→ -
All you are is a bag of particles acting out the laws of physics. That to me is pretty clear.
→ -
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?
→ -
There's a picture of my dorm room in the college yearbook as the most messy, most disgusting room on the Harvard campus, where I was an undergraduate.
→ -
I like 'The Simpsons' quite a lot. I love the irreverent character of the whole show. It's great.
