Supersymmetry is a theory which stipulates that for every known particle there should be a partner particle. For instance, the electron should be pai….

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

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

When kids look up to great scientists the way they do to great musicians and actors, civilization will jump to the next level.

The tantalizing discomfort of perplexity is what inspires otherwise ordinary men and women to extraordinary feats of ingenuity and creativity; nothin….

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..

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

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….

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

You should never be surprised by or feel the need to explain why any physical system is in a high entropy state..

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 f….

String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner. I do believe t….

The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers..

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

A unified theory would put us at the doorstep of a vast universe of things that we could finally explore with precision..

I can assure you that no string theorist would be interested in working on string theory if it were somehow permanently beyond testability. That woul….

Einstein comes along and says, space and time can warp and curve, that's what gravity is. Now string theory comes along and says, yes, gravity, quant….

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 i….

The number of e-mails and letters that I get from choreographers, from sculptors, from composers who are being inspired by science is huge..

Free will is the sensation of making a choice. The sensation is real, but the choice seems illusory. Laws of physics determine the future..
