Attention Anonymous Coward
Sure, I don't know anything. My engineering degree is only from Cambridge - I'd never be able to cope with hard sums like that. I'd never remember where to look up the Beaufort formula, having only spent the two years as a Royal Navy navigating officer giving met briefs several times a week. You certainly saw through my pathetic suggestion that a thick journalist might know these things.
Of course your figure is as utterly wrong as mine, you turkey. A 5km/sec wind is >32m/sec, thus it is still just Force 12, or possibly Force 17 if you prefer the unathorised systems used by some down on the China coast. If you're going to call it anything bigger than that, you are joining me in the 'utterly wrong' place. In my case, I'm there on purpose - the purposes of entertainment/generating a bit of interest/making science popular/doing my job. Thus one chooses to make the figure nice and big, and as an added benefit waste less time on a trivial thowaway paragraph. In your case, you're utterly wrong because you aren't very intelligent - unless you actually enjoy making yourself look an arse.
On the matter of conduct. Fair enough, perhaps not your fault that you have no understanding of how grownups normally hold a discussion - no doubt you sacrificed that sort of thing while acquiring your super O-Level maths skills. But just for future reference, you don't know me well enough to address me as 'stupid boy' and call me a liar, even if you are much older than me (very plausible, all the signs of incipient senility are there). Try to remember, you're not standing alone in an alley shouting at the bins just now - you are addressing adults you don't know in public.
Get yourself down to remedial manners, you rude old git.
