When you're cruising down the road in the fast lane and you lazily sail past a few hard-driving cars and are feeling pretty pleased with yourself and then accidently change down from fourth to first instead of third thus making your engine leap out of your hood in a rather ugly mess, it tends to throw you off stride in much the same way that this remark threw Ford Prefect off his.

Technology is the name we give to stuff that doesn't work properly yet

The more I think about our species the more I think we just do stuff and make up explanations later when asked. But it's not true that I would rather write than read. I would rather read than write. To be honest I would rather hang upside down in a bucket than write.

Deep in the fundamental heart of mind and Universe there is a reason.

If the Universe came to an end every time there was some uncertainty about what had happened in it, it would never have got beyond the first picosecond. And many of course don't. It's like a human body, you see. A few cuts and bruises here and there don't hurt it. Not even major surgery if it's done properly. Paradoxes are just the scar tissue. Time and space heal themselves up around them and people simply remember a version of events which makes as much sense as they require it to make.

Many respectable physicists said that they weren't going to stand for this -- partly because it was a debasement of science, but mostly because they didn't get invited to those sort of parties.

Time, we know, is relative. You can travel light years through the stars and back, and if you do it at the speed of light then, when you return, you may have aged mere seconds while your twin brother or sister will have aged twenty, thirty, forty or however many years it is, depending on how far you traveled. This will come to you as a profound shock, particularly if you didn't know you had a twin brother or sister.
