Significant numbers

Some numbers trigger memories, just as names do. Say 318 and I immediately think of the BMW. Then there's 666 - the Mark of the Beast. I have no idea what that might look like ... the footprint of a gigantic hound, perhaps? But then, Claire's drama teacher once told her that All Men are Beasts, so maybe I should look closer to home.

A random example from my former life as a journeyman engineer would be 555, which was a simple integrated circuit with one useful function - it told you when a certain interval of time had elapsed. The chip evolved through several generations and technologies, but to an electronics engineer 555 still means 'timer'.

What follows is a list of numbers that for various reasons have come to mean something to me. They may mean absolutely nothing to you, and it could well be more rewarding to compile your own list than to read mine. Or we could all just go and get a life.
