In many ways a satnav is a miraculous device. A network of US military satellites more than 10,000 miles above the surface of the Earth, each broadcasting a signal with little more power than a 100-watt light bulb, allows a device in your satnav or mobile phone to triangulate your location on the ground to within seven yards or so. The system is so finely tuned that the clocks aboard the satellites must be calibrated to run 38 microseconds a day slower than Earth time to correct for the effects of general and special relativity. This allows your phone to know your location and, after factoring in real-time traffic information,

What happens when 95 per cent of people like something, but 5 per cent of people prefer something else? You might think natural democracy would prevail: that the 5 per cent would acquiesce and go along with the taste of the majority. Not necessarily. In many cultural settings, it is common for a small, intransigent minority to beat a much larger, tolerant majority. If you’re hosting a dinner party, for instance, all it takes is one git with a spurious ‘fenugreek intolerance’ to veto your best lamb curry. You might call this ‘the asymmetry of tolerance’, where certain social systems end up calibrated to suit their most inflexible component. If the majority prefers

I am one of those annoying, mildly claustrophobic people who sit at the end of a row in cinemas. There are plenty of things in life — films, plays, social events — which I can only fully enjoy knowing I can make a sharp exit at any time. It’s not that I leave: I just like to know I can. My idea of hell is a party on a boat. So I am rather enamoured with the new mobile-phone app Qkr, which lets you pay with your phone in some restaurants without waiting for the bill. It’s the honest man’s version of ‘doing a runner’. You check in on your

My heart is pounding, my hands are shaking and there’s a leaden feeling in the pit of my stomach. My pupils are dilated and my digestive process has ground to a halt. My sympathetic nervous system is kicking in and activating its ‘fight or flight’ response. And how do I know all this? Because the subject of ‘Stress, and the Body’s Reaction to It’ is one of the topics on the AQA AS-level psychology syllabus — an exam I’m just about to sit. Stress? I don’t just know about it. I’m living it. Three decades after I last took an exam, I am standing outside the sports hall of my

It’s not quite as bad as we feared: Sealed Air, the company in New Jersey that makes bubble-wrap, is not yet discontinuing poppable bubble-wrap. But its newly designed sibling, non-poppable bubble-wrap, surely spells the end for the real thing: it’s cheaper to ship, because it leaves the factory airless and thus can be ‘flat-packed for your convenience’. The companies who receive it will need to buy an expensive pump to fill the reams of polythene with columns of air, and that air will be beyond the popping power of human fingertips. Panic broke out among the bubble-wrap-popping millions across the globe on hearing the news of the threat to their

A year into his sentence on 12 counts of indecent assault, it doesn’t look like Rolf Harris has developed much of a sense of remorse. After seeing Mr Harris’s latest foray into song writing, his victims’ lawyer has said he mustn’t be given parole, and she has a point. Theodore Dalrymple (also known as Anthony Daniels), then a prison doctor, described in 1994 the baffling ability of violent criminals to avoid that uncomfortable emotion. A murderer came back from court having been sentenced to life imprisonment. A period of depression is, of course, to be expected after such a sentence, but this man was angry, not depressed. He was red

I don’t like to make business predictions, but — barring some apocalypse — I suspect there will be plenty of estate agents around in 2065, and occupying prominent high-street shopfronts just as they do now. This may seem an absurd prediction: after all, almost no one now uses an estate agent to find a house: we go to property websites instead. And, since we all assume the purpose of an estate agent is to find buyers for a house, a role usurped by Rightmove and Primelocation, we think the remaining days of the estate agency are few. However, perhaps the principal role of an estate agent is not to find

Go to a branch of Whole Foods, the American-owned grocery shop, and you will see huge posters advertising Whole Foods, of course, but — more precisely — advertising how virtuous Whole Foods is. A big sign in the window shows a mother with a little child on her shoulders (aaaah!) and declares: ‘values matter.’ The poster goes on to assert: ‘We are part of a growing consciousness that is bigger than food — one that champions what’s good.’ This a particularly blatant example of the increasingly common phenomenon of what might be called ‘virtue signalling’ — indicating that you are kind, decent and virtuous. We British do it, too. But

Have you noticed how often adults – particularly of the earnest, nagging variety who work in the public sector – are behaving like children? I don’t mean acting childishly, but literally behaving like children. Last week delegates to the NUS women’s conference were using ‘jazz-hands’ instead of clapping – in case it should trigger an anxiety attack. I can think of five-year-olds who would squirm at that spectacle. Meanwhile, Brown University in America recently debated sexual assault on campus. A serious topic, but the authorities deemed it necessary to create a ‘safe space’ full of play-doh, bubbles, calming music and colouring books. Yes, colouring books. But perhaps we shouldn’t be surprised. As the New York Times
