I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.

It is not clear that intelligence has any long-term survival value.

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

It matters if you just don't give up.

The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired.

The laws of science do not distinguish between the past and the future.

The progress of the human race in understanding the universe has established a small corner of order in an increasingly disordered universe.

It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was twenty-nine years.

Equations are just the boring part of mathematics. I attempt to see things in terms of geometry.
