Physicists have come to realize that mathematics, when used with sufficient care, is a proven pathway to truth.

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

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, or happening that brought the universe into existence - started off the universe in an extraordinarily special, highly ordered state of low entropy.
