Science fiction weapons can be strangely mundane

This is what laser weapons ought to look like

I enjoy reading science fiction (or watching a sci fi movie) as much as the next nerd, and it's fascinating to speculate on the similarities and differences between the science and technology in the fictional world and reality.

In some areas we have gone far beyond the imagination of the fiction writers; in others we haven't come close. One obvious area that we've lagged pretty far behind is in lasers, phasers, blasters or whatever you want to call them. I think one of the most interesting aspects of the Battlestar Galactica reboot is that once they'd established the technology of space flight, almost every other bit of technology from fridges and phones to weaponry was pretty much late 20th century standard. So any shooting was done with old fashioned bullets. And it's certainly the way things have been in the real world - until now.

The US has been experimenting with laser weapons on ships for some while, but they've now come up with a demo video of their most impressive toy to date. Ships make ideal platforms for lasers. They're big enough to deal with the large-scale equipment needed to power up a major laser, and ships are infamously bad places to fire weapons with recoil (this is why rockets were developed as weapons in the West), from which lasers are wonderfully free.

So here you go: fill your boots with the sight of a genuine laser weapon in action, doing suitably destructive (and pinpoint targeted) stuff. The only disappointment is, if course, it doesn't really look like it's a laser in action. If there's one thing Hollywood has taught us, it's that when you fire a laser you see a bright, coruscating beam in the air. But here the operator presses a button on his video-game like console and instantly the hit happens with nothing visible or audible in between.

It's not likely to be the future of warfare on a large scale, at least for some considerable time, as these things are extremely expensive and quite possibly a little temperamental right now. But this a reality. To quote the US Navy Office of Information 'Laser weapon capability is now allowing operation aboard ships at sea.' Which I think, in English, means 'We are ready to use this for real.'

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 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 recent 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 ex

Mirror, mirror

A little while ago I had the pleasure of giving a talk at the Royal Institution in London - arguably the greatest location for science communication in the UK. At one point in the talk, I put this photograph on the screen, which for some reason caused some amusement in the audience. But the photo was illustrating a serious point: the odd nature of mirror reflections. I remember back at school being puzzled by a challenge from one of our teachers - why does a mirror swap left and right, but not top and bottom? Clearly there's nothing special about the mirror itself in that direction - if there were, rotating the mirror would change the image. The most immediately obvious 'special' thing about the horizontal direction is that the observer has two eyes oriented in that direction - but it's not as if things change if you close one eye. In reality, the distinction is much more interesting - we fool ourselves into thinking that the image behind the mirror is what's on ou
