There’s an intriguing conversation on YouTube between Mark Carney, former governor of the Bank of England, and the artist Damien Hirst. It will be easy to find on Google, since these are not names normally found on the same page. Ten minutes in, Hirst makes an engaging observation about the value we attach to art. He explains that art collectors will pay anything for a painting, even though the raw materials cost almost nothing. It’s a hundred quid’s worth of canvas, wood and paint, but you can sell it for millions. ‘The problem happens when you make something like a diamond skull. Suddenly people want to know what you paid

I often argue that, in theory at least, well-made cocktails are indisputably better than wines costing 20 times more. My argument runs as follows. In making a cocktail, you can mix, in any combination you wish, any of the liquids known to humanity. In making a wine, you are stuck with using grape juice harvested by grumpy Frenchmen from scrubland east of the Gironde. Mathematically, the odds that the best drink you can generate derives only from a few bunches of such grapes is so small as to be infinitesimal. Besides, almost no one drinks grape juice, and nobody has ever seriously tried to sell non-alcoholic wine. If it really

As a wise colleague once said: ‘Yesterday is a great time to buy a computer, because you have already enjoyed it for a day. Alternatively, buy a computer tomorrow. The computer you buy tomorrow will be both faster and cheaper than the computers available now. On no account, however, should you ever buy a computer today.’ One factor delaying our adoption of electric cars is that experience has taught us it pays to wait when buying anything with a plug. There is a huge impetus to buy property because, over time, your options get fewer and dearer. But when contemplating the purchase of an electric car we assume every year

Among the horrors, some aspects of lockdown were bizarrely less gruelling than expected; indeed for some people, the experience was mildly positive. It’s time to ask ourselves why. One possible explanation is ‘jomo’ — the joy of missing out. Much ostensibly voluntary human activity is not really voluntary at all. Like dressing for dinner in the 19th century, many elements of life are performative — things done to signal commitment or driven by social pressure. John Stuart Mill observed that ‘Society can and does execute its own mandates… and practises a social tyranny more formidable than many kinds of political oppression, since, though not usually upheld by such extreme penalties,

Back in late 2019 I met someone from Zoom who was visiting London. The company, then as now, offered free video-conferencing calls for up to 40 minutes, but charged a fee of around £10 a month to users who wanted longer calls. Towards the end of the conversation, I flippantly asked what I thought was a hypothetical question: ‘How much would you charge to give full Zoom access to the whole UK population?’ I didn’t think much more about it, but to my surprise they came back to me a few days later: ‘If you know anyone in the government who’d be interested in this, we’d like to talk.’ In

Dear Sir, I beg to introduce myself to you as a clerk in the Accounts Department of the Port Trust Office at Madras on a salary of only £20 per annum. I am now about 23 years of age. I have had no university education but I have undergone the ordinary school course… I have made a special investigation of divergent series in general and the results I get are termed by the local mathematicians as “startling”. This was the opening of the letter written by the Indian maths prodigy Srinivasa Ramanujan to Professor G.H. Hardy at Trinity College, Cambridge in January 1913. The penny post was the first network
