Boston's freeway system is insane. It was clearly designed by a person who had spent his childhood crashing toy trains.

The great failure in education, much of the time, is the lack of excitement and stimulus

If you were designing an organism to look after life in our lonely cosmos, to monitor where it is going and keep a record of where it has been, you wouldn't choose human beings for the job. But here's an extrememly salient point: we have been chosen, by fate or Providence or whatever you wish to call it. As far as we can tell, we are the best there is. We may be all there is. It's an unnerving thought that we may be the living universe's supreme achievement and its worst nightmare simultaneously.

You can always tell a Midwestern couple in Europe because they will be standing on a traffic island in the middle of a busy intersection looking at a windblown map and arguing over which way is west.

Protons give an atom its identity, electrons its personality.

Perhaps it's my natural pessimism, but it seems that an awfully large part of travel these days is to see things while you still can.

Being a pessimist is just such a gloomy way of looking at things, so I have to hope for the best - life wouldn't be worth living if we didn't have hope. And I also do think that human beings often do do wonderful, correct, brilliant things. So, on balance, I'd like to be optimistic about the future.
