I regularly get emails as well as posts on my Facebook page/Twitter feed from readers, and 95% of them are lovely or wacky - both are fun. But sometimes I get some that are ANGRY because I've got something wrong - and then, I must admit, my heart drops. Because I do make mistakes - everyone does. I think I know science reasonably well, but I write about every topic under the sun, and it's easy enough to make a slip.
Luckily, in at least half the cases, I can go from depressed to smug in one easy leap. For your entertainment, I'm going to share the latest email I have received and my response.:

Dear Sir,
Began reading your latest book, “Final Frontier”, but had to quit after reading page #65, when it became obvious that you really have no clue as to what you are talking about.
You are discussing the construction of a paternoster-type space elevator on the Moon, when you state “The mechanism would be designed to swing at just the right speed to match THE ROTATION OF THE MOON”. Unless I have been lied to by every book on planetary physics that I have ever read, the Moon is tidally locked to the Earth, AND HAS NO ROTATION. Perhaps you somehow missed that small bit of information?
As I said, I stopped reading the book at that point, and will probably avoid your works in the future.
Now, I must admit, if I did email someone to tell them what was wrong with their book (which, frankly I wouldn't, and I wouldn't recommend doing) I would think for a few minutes about what I was saying.Began reading your latest book, “Final Frontier”, but had to quit after reading page #65, when it became obvious that you really have no clue as to what you are talking about.

Hello,
Thank you for your email. I do make mistakes and I am happy to admit to them - everyone is human - but in this case, I didn’t. The Moon is orbiting the Earth. If it didn’t rotate, it would not be able to keep the same face towards the Earth all the time. It is indeed tidally locked - but this means having the right speed of rotation to match its orbit, not that it doesn’t rotate at all.
Best regards,
Brian Clegg
