About Time

Sean Carroll writes about time itself in Discover: 

Intuitively we think that the “now” is real, while the past is fixed and in the books, and the future hasn’t yet occurred. But physics teaches us something remarkable: every event in the past and future is implicit in the current moment.

Finally somebody who thinks about things that matter (ha!). Seriously, some of this stuff might not be entirely surprising for anyone interested in physics, but the implications are enormous.
