First law of Exciting News: Inevitably, when you get an email from some company entitled “exciting news” it is going to contain an announcement that they have “merged with” (been taken over by) a “major partner” (a larger, rather more anonymous company), and that they are “looking forward to the opportunities that are offered by this exciting new development” (ready to make some more money from you by offering you a slightly diminished service level).

One of the points where mathematics and day-to-day intuitions jar is in estimating numbers of combinations and similar combinatorial problems. I’ve just made a booking on Eurostar, and my confirmation code is a 6-letter code. Surely, my intuitive brain says, this isn’t enough; all of those people going on all of those journeys on those really long trains, day-in, day-out. Yet there are a vast number of possibilities; with one letter of the 26 letter alphabet for each of the 6 letters in the code, there are 26^6=308,915,776 possible combinations. Given that there are 10 million Eurostar passengers each year, this is enough to allocate unique codes for passengers for around thirty years. It then make you wonder why some codes are so long, like the 90-digit MATLAB registration code that I had to type in by hand a couple of years ago.
Love it that this bookshop in Margate manages to divide books into three categories: “General Interest”, “Extra Stock” and “Whatever” (there are some other shelves with more specific categories).
Thinking about bookshops and their categorisation schemes reminds me of a bookshop from years ago on Queen’s Road in Brighton, just down from the station, which had, in addition to books on the shelves, large piles of books in the middle of the floor as if dumped there by a dumper truck. At the back of the shop, there was a shelf of pornographic books; in place of the usual bookseller euphemism of “Erotica” as a header for the section, this shop had plumped for the rather more direct word “Filth”.
Amazingly I have just found a picture of that very shop, and an article from The Argus about its closure (well, abandonment) in 2002; the wonders of the interweb, eh?
