If string theory is right, the microscopic fabric of our universe is a richly intertwined multidimensional labyrinth within which the strings of the ….

Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics t….

I believe we owe our young an education that captures the exhilarating drama of science..

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..

The revelation we've come to is that we can trust our memories of a past with lower, not higher, entropy only if the big bang - the process, event, o….

Art makes us human, music makes us human, and I deeply feel that science makes us human..

Most scientists like to operate in the context of economy. If you don't need an explanatory principle, don't invoke it..

One of the wonders of science is that it is completely universal. It crosses national boundaries with total ease..

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….

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

General relativity is in the old Newtonian framework where you predict what will happen, not the probability of what will happen. And putting togethe….

I can't stand clutter. I can't stand piles of stuff. And whenever I see it, I basically just throw the stuff away..

In essence, we string theorists have been trying to work out the score of the universe, the harmonies of the universe, the mathematical vibrations th….

I believe the process of going from confusion to understanding is a precious, even emotional, experience that can be the foundation of self-confidenc….

Over the centuries, monumental upheavals in science have emerged time and again from following the leads set out by mathematics..

When I give this talk to a physics audience, I remove the quotes from my 'Theorem'..

Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers..

In my own research when I'm working with equations, I never feel like I really understand what I'm doing if I'm solely relying on the mathematics for….

...things are the way they are in our universe because if they weren't, we wouldn't be here to notice..

Quantum Mechanics is different. Its weirdness is evident without comparison. It is harder to train your mind to have quantum mechanical tuition, beca….

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..
