Liquid gold

This is one for the Mac users amongst you (or those with secret Mac cravings) - I have fallen in love with a little app called Liquid.

One of the biggest surprise when you come into the Mac world from the outside is how obsessed the heavy-duty Maccers are with doing things with keyboard shortcuts. Given that the Mac popularised the mouse, it's rather amusing that Macfans just love to do as much as possible without ever taking their hands off the keyboard. Now this works quite well for me - in Windows, I always used to cut and paste using keystrokes, for instance. But when it comes to the Mac much more seems frequently done this way, and there are plenty of helper apps like Alfred to extend the possibilities.

Liquid is a productivity tool for people who often look things up - ideal for a writer. Let's say I'm writing about Jupiter and wanted to check a fact in Wikipedia (yes, it is possible to do this - the science coverage is usually very good). I've just typed Jupiter in Word (say). All I do is highlight the word Jupiter and hit Liquid's activating key combination followed by RW (short for Reference Wikipedia). Zippo zappo and Wikipedia opens on the page for Jupiter.
At the point I've typed Cmd-§R but not the W for Wikipedia

I can equally look things up in (say) a dictionary or Wolfram Alpha, can search the likes of Amazon and Google or can do an instant conversion, say from Celsius to Fahrenheit (something I do quite frequently). This takes a few more key presses, but it's still just select, activate keypress then C(onvert) T(emperature) C(elsius) F(ahrenheit).

It is brilliant. All that I have described so far is in the free version, but I've gone for the paid for 'Pro' version, partly because I think it is worth £2.99 and only fair to pay for it, and partly because this adds translations and the ability to include your own searches. So, for instance, I can now search Amazon.co.uk as well as Amazon.com, can reference the full OED, which I have online access to, rather than the the cut down dictionary, and can make use of my own www.popularscience.co.uk site (or this one).

The app's not perfect - in fact it can be rather frustrating. The default key press is Cmd-@ (for Windows users, Cmd is the equivalent of Ctrl in keyboard shortcuts). But @ is a shifted character, so it takes three fingers to do. I have switched this to Cmd-§, which is just two keys, so practical with one hand. But changing the setting isn't as easy as you might think, as you have to do it in the Mac's services control panel, as Liquid has to act at a low level to intercept keypresses. The other irritation is that occasionally the key press does nothing, and occasionally the text you highlight isn't copied into the app. You can still type what you are searching for, either calling up the app with the keypress or using its little toolbar thingy - and sometimes that is better because you might not have typed the text you want to look up - but it is a real pain when it doesn't work, as to be efficient, you want to type the control keys without needing to check the word has passed through.

Despite these minor moans, though, it's a real winner.

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
