Astronomy

Versailles was a palace of science, as Anna Ferrari shows in this stimulating and innovative study, accompanying a dazzling exhibition of the same title at the Science Museum, London (until 21 April). Soldiers were subjected to electricity experiments in the Galerie des Glaces. The king watched the dissection of an elephant or a horse in the Menagerie. The latest globes and clocks, microscopes and barometers, miracles of precision and beauty, were, and in some cases still are, on display in the royal apartments. The gardens were exercises in trigonometry and hydraulics as well as planting. Louis XV had the largest and most varied plant collection in Europe. On 19 September

Where is science bred? Is it where the physical circumstances are right – clear skies for astronomy, for example? Where raw materials are abundant – coal for organic chemistry? Where minds freely meet? Where the enlightened patron rules? Violet Moller’s first book, The Map of Knowledge, examined the spread through the centuries of the ideas of Galen, Euclid and Ptolemy by focusing on seven, mainly Mediterranean cities, from Alexandria to Venice, where scientific knowledge was gathered, augmented and promulgated anew, ensuring the survival of classical learning into the modern period. But why these men and these cities? Are people or places the drivers? Is geography a reliable guide, a storytelling

In 1928, a young physicist and engineer named Karl Jansky began working at Bell Telephone Laboratories, tasked with investigating any sources of static that could interfere with long-distance radio communication. Cobbling together a system of antennae on a merry-go-round, he successfully found that thunderstorms were annoying in just this way. But there was a small bit of noise left over, and he kept scanning the sky to locate the culprit. To his surprise, he eventually found it was coming from Sagittarius in the centre of the Milky Way. He christened it ‘star-noise’. We now know that he had correctly identified the emanations from a supermassive black hole; and, quite by

There are many ways to measure the course of human history and each will give an insight into one or more of the various qualities that have made us the most successful great ape. Every major advance, whether in war or art or literature, requires imagination, that most amazing of human capacities, and the ability to ask ‘What if?’ – to take the world from a different perspective. Nowhere is this more apparent than in the history of science. While there is an inherent provincialism in revolutions in art and literature, progress in science is universal, and moves, like Dante’s Hell, in concentric circles of ever deeper understanding. It is

In 2020, an American pilot and daredevil named ‘Mad Mike’ Hughes launched himself in a homemade steam-powered rocket, hoping to achieve enough altitude to prove to himself that the Earth was flat. Unfortunately, the rocket crashed and Mad Mike was no more. ‘I’m not going to take anyone else’s word for it, or Nasa, or especially Elon Musk with SpaceX,’ he had once explained in an interview. ‘I’m going to build my own rocket right here and I’m going to see it with my own eyes what shape this world we live on is.’ In this way he became a martyr to the modern conspiracy theorist’s mantra: ‘Do your own

It seems something of a disservice to a work of this seriousness to say how beautiful it is, but that is what will first strike the reader. Open this book and if you can prise yourself away from its wonderful marbled end papers, with their swirls and drifts of deepest blue, brilliant flashes of rusty orange, rivulets of ochre, inky spheres and floating masses of fiery red, you will find yourself taken back to the Enlightenment world of Johann Gabriel Doppelmayr’s Celestial Atlas and an age in which Europe’s polymaths were as interested in the discoveries of science as they were in the literary and artistic culture of the day.

Thirty-two years ago the young Nicholas Crane, who would go on to become one of England’s most esteemed television geographers, set out to woo a young woman by spiriting her off to the unfailingly romantic landscape of Chimborazo and Cotopaxi. The couple spent their high-altitude idyll walking the hills in hobnail boots, making river passage in dugout canoes and boarding a Quito-bound steam train through the Andes, run by the estimable Empresa de Ferrocarriles Ecuatorianos. Their journey had its moments: at one stage both parties were to be found at 13,000 feet, crusted with ice and huddled overnight from the gales inside a pair of plastic rubbish bags; they then

This book, soaked like the Dutch Republic itself ‘in ink and paint’, is enchanting to the point of escapism. The author calls it ‘an interior journey into a world of luxury and leisure’. It is more than that. What he writes of Christiaan Huygens’s milieu is true also of his book: ‘Like a Dutch interior painting, it turns out to contain everything.’ Hugh Aldersey-Williams says that Huygens was the first modern scientist. This is a delicate argument to make: the word ‘scientist’ didn’t enter the English language before 1834. And he’s right to be sparing with such rhetoric, since a little of it goes a very long way. What inadvertent

We can probably blame George and Ira Gershwin. It was that brilliant duo who, in 1937, penned the memorable lyric ‘They all laughed at Christopher Columbus when he said the world was round’. The song has been recorded by at least 15 artists over the years, from Fred Astaire to Lady Gaga, and is embedded in the consciousness of the West. But its headline message — medieval people are stupid — is total nonsense. No one, as Professor Seb Falk points out in this brilliant study of medieval astronomy and learning, ever disbelieved the world was round, and medieval people were far cleverer than they get credit for. Half the
