To tell you the truth, I've never met anybody who can envision more than three dimensions. There are some who claim they can, and maybe they can; it's hard to say.
-
Relativity challenges your basic intuitions that you've built up from everyday experience. It says your experience of time is not what you think it is, that time is malleable. Your experience of space is not what you think it is; it can stretch and shrink.

Intelligence is the ability to take in information from the world and to find patterns in that information that allow you to organize your perceptions and understand the external world.
-
For me it's been very exciting to contribute to the public's understanding of how rich and wondrous science is.
-
There's no way that scientists can ever rule out religion, or even have anything significant to say about the abstract idea of a divine creator.
-
I do feel strongly that string theory is our best hope for making progress at unifying gravity and quantum mechanics.
-
How can a speck of a universe be physically identical to the great expanse we view in the heavens above?
-
There was a time when 'universe' meant 'all there is.' Everything. The whole shebang. The notion of more than one universe, more than one everything, would seemingly be a contradiction in terms.
-
Black holes provide theoreticians with an important theoretical laboratory to test ideas. Conditions within a black hole are so extreme, that by analyzing aspects of black holes we see space and time in an exotic environment, one that has shed important, and sometimes perplexing, new light on their fundamental nature.
-
I'd say many features of string theory don't mesh with what we observe in everyday life.
-
Exploring the unknown requires tolerating uncertainty.
-
The funny thing is, I sometimes get the impression that some people outside of the field think that there's some element of security that we have in working on a theory that hasn't made any predictions that can be proven false. In a sense, we're working on something unfalsifiable.

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.
-
I enjoy reading blogs, but am not interested in having my spurious thoughts out there.
-
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.
-
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?
-
We might be the holographic image of a two-dimensional structure.
-
Science is a self-correcting discipline that can, in subsequent generations, show that previous ideas were not correct.
-
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.
-
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. He didn't find it, but we think we're hot on the trail.
-
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.
-
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.
-
The melded nature of space and time is intimately woven with properties of light speed. The inviolable nature of the speed of light is actually, in Einstein's hands, talking about the inviolable nature of cause and effect.
-
The idea that there could be other universes out there is really one that stretches the mind in a great way.
