Edward FitzGerald had a good story about rowing across Lake Windermere at the end of May 1835 with his old friend Alfred Tennyson. As they rested on their oars and gazed into the clear, still water, Tennyson recited some lines from his work in progress, ‘Morte d’Arthur’, describing how the Lady of the Lake fashioned Excalibur out of sight: ‘Nine years she wrought it, sitting in the deeps/ Upon the hidden bases of the hills.’ Then he gave himself a little pat on the back: ‘Not bad that, Fitz, is it?’ The lines are better than not bad, as they imagine an invisible process of creation by incorporating several fragments

Every doctor can remember a time when bacterial infection laid waste to their patient with hair-raising speed and virulence. The most indelible for me occurred a decade ago during surgical night shifts. Again and again I was called to the bedside of a young woman with the ‘flesh-eating bug’, or necrotising fasciitis. By the time she’d presented to A&E, a recent graze to her leg was causing such disproportionate pain that her family had been forced to carry her. When the surgeons opened up the limb, they found carnage. Group A streptococcus – a bacterium that benignly colonises the throats and skin of millions of us – had burrowed from

What is your p(doom)? This is the pseudo-scientific manner in which some people express the strength of their belief that an artificial superintelligence running on computers will, in the coming decades, kill all humans. If your p(doom) is 0.1, you think it 10 per cent likely. If your p(doom) is 0.9, you’re very confident it will happen. Well, maybe ‘confident’ isn’t the word. Those who have a high p(doom) and seem otherwise intelligent argue that there’s no point in having children or planning much for the future because we are all going to die.

Ettore Majorana vanished in March 1938. According to Frank Close in Destroyer of Worlds, the 31-year-old Sicilian physicist ‘probably understood more nuclear physics theory than anyone in the world’, and was hailed by Enrico Fermi as a ‘magician’, in the elevated company of Newton and Galileo. Majorana was also an ardent fascist; yet he was haunted by the destructive potential of his work on mapping the nucleus. His disappearance – perhaps a suicide; more likely a new, incognito life in South America – has been related to an anguished remark he made to a colleague: ‘Physics has taken a bad turn. We have all taken a bad turn.’ Majorana is

In 1941, as it entered the second world war, the US Army barely bested Bulgaria’s for size and combat readiness. Nor did US forces have very much idea of what conditions were like in their new theatres of operation. In the winter of 1942, hot-weather gear and lightweight machinery landed in the deserts of North Africa where hot and dry conditions were assumed to persist throughout the year. Men froze half to death, even as their digging equipment foundered in winter mud. Sand, Snow and Stardust is the story of how the US military shed its ignorance and, by harnessing logistical intelligence and environmental knowledge, turned America into a global

In 1997 the world chess champion Garry Kasparov was beaten by an IBM computer system called Deep Blue. It had defied all expectations, exploring some 300 million possible moves in one second. The most that skilled chess players can contemplate is about 110 moves at any given time. It was a seminal moment in the advance of artificial intelligence – even if not fully understood, writes Richard Susskind in How to Think About AI. People did not wholly grasp the impact of the exponential power of computers, nor that new ways would be found to develop systems that could achieve human expert-level performance. Fast forward to 2016 and to AlphaGo,

Since reading Helen Gordon’s The Meteorites, I keep catching myself in imaginary conversation with an Essex thatcher called Frederick Pratt. On 9 March 1923, he was working in a wheat field at Ashdon Hall Farm, near Saffron Walden, when he heard a strange ‘sissing’ sound and looked up to see ‘the earth fly up like water’. He later dug up, from a depth of two feet beneath the surface of the field, a stone weighing 1.27kg that had fallen from the sky. He took it to the police station, then on to the vicar, who shipped it off to the Natural History Museum. There we know it was classified as

A.J. Ayer and other thinkers linked to the Vienna Circle famously contradicted themselves. A claim such as ‘all truths are scientific truths’ cannot itself be verified scientifically. So whether the assertion is true or false, it follows that there is at least one fact which isn’t a physical fact. Thus metaphysics buries its own undertakers. Yet Ayer’s ideas survive today in mutated form and influence other subjects besides philosophy. Though partly infected by relativism, the humanities have witnessed a growing impulse to redescribe everything in material and supposedly objective terms. The move is reductive. It involves restricting us to a world of causes rather than reasons, sounds rather than music.

Is this what it felt like in the months before August 1914? Or during the years leading up to September 1939? The discussion around artificial intelligence produces a deep foreboding that we are in the grip of forces largely beyond our control. Are we sleepwalking towards disaster? That is the feeling I have after reading Genesis, a collaboration by Eric Schmidt, the former CEO of Google, Craig Mundie, the former chief research and strategy officer at Microsoft, and Henry Kissinger, who died, aged 100, soon after completing this book. They have crafted a holistic analysis of the social, political, psychological and even spiritual impacts that a superior machine intelligence would

In Paris in 1740 the hangman publicly burned his most famous book. In England some of the best and brightest – Alexander Pope, Henry Fielding, Bishop George Berkeley, Jonathan Swift and John Wesley – queued up to destroy his reputation. The book was The Fable of the Bees (1714) and the author was Bernard Mandeville, popularly known as the Man-Devil. After Mandeville’s death in 1733, Samuel Johnson, perhaps the wisest Englishman who ever drew breath, admitted that the book had ‘opened my views into real life very much’. And David Hume, the great British philosopher, said the Man-Devil was, in fact, one of the most important figures in the development
