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

...quantum mechanics—the physics of our world—requires that you hold such pedestrian complaints in abeyance.

— Brian Greene

In any finite region of space, matter can only arrange itself in a finite number of configurations, just as a deck of…

I think it's too fast to say that all sci-fi ultimately winds up having some place in science. On the other hand,…

I think math is a hugely creative field, because there are some very well-defined operations that you have to work within. You…

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll…
