The Romans never invented the stirrup. It took 50 years after the invention of canned food for someone to invent the can opener. And we put a man on the moon before we put wheels on suitcases. This seems silly. But it is worth understanding each invention in context: often, a concatenation of other events
I’d like to propose a new scientific institution: the IUT, or Institute of Underrated Technology. Rather than trying to invent yet more bloody things, it will instead be devoted to helping us derive greater value from things we can do already using technology which already exists. Innovation is a two-stage process. First you discover something;
In past years, I have been a critic of HS2. I might now change my mind. One simple tweak might make HS2 worthwhile — while saving the taxpayer most of its £60 billion cost. For this to work, all you need to understand is that 1 x 200 is not the same as 200 x
I recently saw a series of photographs depicting a rural home in China. Pride of place in a grimly furnished main room was given to a gargantuan new flat-screen television, while the sole toilet was a hole in the ground in an outside shed. What strange priorities, I thought. On reflection, though, under the same
It has become commonplace for news reports to refer to almost any civic unrest, or even unusual patterns of voting, as evidence of ‘resurgent nationalism’ — implicitly suggesting a visceral hatred of foreigners and a desire to set the clock back to the glory days of racial homogeneity and casual homophobia. We should be wary
During the second Gulf war, simply out of curiosity, I found myself visiting the website of a giant American mercenary organisation. At the top of its home page I was surprised to see the words ‘online shop’. Thinking I could perhaps order an airstrike, or a fleet of Humvees to collect my daughters from school,
I have just spent a weekend planning a family trip to Chennai and Hyderabad. Since some of the flights are booked with reward points and some are not, our flights are under three separate booking numbers, each of which requires a separate login. I also had to print out booking confirmations from three different hotels,
In recent years, much scrutiny has been paid to the workings of social media algorithms. Driven by escalating competition for human attention, social media sites became filled with negative or controversial posts, because these attract more protracted engagement than anything else. Since reader attention attracts revenues, any profit-seeking algorithm will learn to highlight divisive content
Imagine a world where employers judged applicants solely on their dress. Anyone in frayed clothes or scuffed shoes would never get a job. This would be unfair to poorer applicants so, in the name of equality, the government might offer favourable loans up to £1,000 to buy interview clothing. At first glance this would seem
Most people were scandalised by John McDonnell’s proposal to promote a four-day working week. But before we get incensed about giving people more leisure during their working life, we need to ask another question. If it really is so vital to the economy that people spend more time at work, then why does the government
A few weeks ago I flew to Sydney to speak at a conference. The first leg was on the new Qantas route non-stop from London to Perth, the UK’s longest flight. Two million people live in Perth, of whom 250,000 were born in the UK, so the route makes sense. But I was dreading the
A month ago I wanted to travel to Bath for a 60th birthday party. From Kent, this either involves a Tube journey to Paddington or traversing the south-western stretch of the M25, where — in the rare moments you are not in stationary traffic — you have the even worse experience of driving over 10,000
Which is more diverse: London or Devon? That’s not a trick question. London is much more diverse than Devon. But let’s tweak the question slightly. Which is more diverse: a pub in London or a pub in Devon? Here the answer is not so easy. Though low in ethnic diversity, a pub in Devon might
Is it me, or is business becoming a teeny-weeny bit Stalinist? Common features include 1) Paranoia about political ideology; 2) Snitching; 3) Fatuous targets and metrics; 4) Unquestioning faith in technology; 5) Huge, economically unproductive bureaucracies; 6) Overinvestment in education; 7) Preference for theory over experience; 8) An obsession with rockets. An acquaintance in the
In late 1973 the graduate admissions department at UC Berkeley discovered that for the forthcoming year it had awarded places to 44 per cent of male applicants and only 35 per cent of women. Concerned about possible lawsuits or bad publicity, they approached Peter Bickel, a professor of statistics, to analyse the data in more
H.L. Mencken once said that a rich man is anyone who earns more than his wife’s sister’s husband. The anthropologist David Graeber takes a slightly different view. When I interviewed him about his wonderful book Bullshit Jobs, he explained that, rather like the Laffer curve, there is an optimal amount of wealth for anyone to
When I saw my first jogger in Wales in the early 1970s, I assumed he was running away from the police. Presumably joggers were familiar in California by then, but not elsewhere. I can’t imagine any of the characters in Goodfellas going jogging, any more than I can imagine Rick in Casablanca going to a
The behavioural scientist Dan Ariely once found himself chatting to a locksmith with a curious problem. The better he became at replacing locks, the less he got paid. In the early days, he explained, he might wrestle for hours with a jammed lock, but because his inexperience made his job look difficult, his customers would
An Iranian friend of mine recently brought me some gaz from Isfahan. Commonly known as Persian nougat, gaz is perhaps the most delicious thing I have ever eaten. The only thing to avoid is learning how it is made. Pistachio nuts are mixed with ‘honeydew’ collected from the angebin plant of the Zagros mountains, a
History records many well conceived and apparently logical grand plans for the betterment of mankind. Sadly such ideas almost always fail. Why is this? One possibility is that they fail precisely because they are logical. The dictates of logic require the existence of universally applicable laws. But humans, unlike atoms, are not consistent enough in
