Brian lassos the moon

It doesn't matter how many books you have published, there's still something special about getting your hands on the first copy of the finished product - and never more so than my new book, How Many Moons Does the Earth Have?, as the publisher, Icon Books, has done a great job, giving it a really impressive textured cover.

Sadly, you can't buy a copy yet - not til November - but you can already preorder it on Amazon and elsewhere, and I think it will make an ideal gift for hard-to-buy-for people (and something of a bargain at £6.99). In fact there may be one exception to this wait - I'm doing an event at Lichfield Literary Festival on October 8 when we hope there will be early copies available on sale: see the festival's website for details.

It's a science quiz book, in part because if you like attending quizzes, it can be frustrating that they don't have enough/good enough quality science questions. But you don't need to be running a quiz to use it (in fact I suspect most readers won't) - the idea is rather to test yourself with the questions and then turn the page to find the answer, often, I hope, surprising, and a pageful of interesting material expanding on the answer.

It's a bit like taking part in your own version of QI without the pompousness and the answers they get wrong (which is reflected in the title of the book).

Here's some bumf from the back cover:

Why I hate opera

If I'm honest, the title of this post is an exaggeration to make a point. I don't really hate opera. There are a couple of operas - notably Monteverdi's Incoranazione di Poppea and Purcell's Dido & Aeneas - that I quite like. But what I do find truly sickening is the reverence with which opera is treated, as if it were some particularly great art form. Nowhere was this more obvious than in ITV's 2010 gut-wrenchingly awful series Pop Star to Opera Star , where the likes of Alan Tichmarsh treated the real opera singers as if they were fragile pieces on Antiques Roadshow, and the music as if it were a gift of the gods. In my opinion - and I know not everyone agrees - opera is: Mediocre music Melodramatic plots Amateurishly hammy acting A forced and unpleasant singing style Ridiculously over-supported by public funds I won't even bother to go into any detail on the plots and the acting - this is just self-evident. But the other aspects need some exp

Is 5x3 the same as 3x5?

The Internet has gone mildly bonkers over a child in America who was marked down in a test because when asked to work out 5x3 by repeated addition he/she used 5+5+5 instead of 3+3+3+3+3. Those who support the teacher say that 5x3 means 'five lots of 3' where the complainants say that 'times' is commutative (reversible) so the distinction is meaningless as 5x3 and 3x5 are indistinguishable. It's certainly true that not all mathematical operations are commutative. I think we are all comfortable that 5-3 is not the same as 3-5. However. This not true of multiplication (of numbers). And so if there is to be any distinction, it has to be in the use of English to interpret the 'x' sign. Unfortunately, even here there is no logical way of coming up with a definitive answer. I suspect most primary school teachers would expands 'times' as 'lots of' as mentioned above. So we get 5 x 3 as '5 lots of 3'. Unfortunately that only wor

Why backgammon is a better game than chess

I freely admit that chess, for those who enjoy it, is a wonderful game, but I honestly believe that as a game , backgammon is better (and this isn't just because I'm a lot better at playing backgammon than chess). Having relatively recently written a book on game theory, I have given quite a lot of thought to the nature of games, and from that I'd say that chess has two significant weaknesses compared with backgammon. One is the lack of randomness. Because backgammon includes the roll of the dice, it introduces a random factor into the play. Of course, a game that is totally random provides very little enjoyment. Tossing a coin isn't at all entertaining. But the clever thing about backgammon is that the randomness is contributory without dominating - there is still plenty of room for skill (apart from very flukey dice throws, I can always be beaten by a really good backgammon player), but the introduction of a random factor makes it more life-like, with more of a sense
