“... In 1617, the governors of the Dutch East India Company placed an order for goods to be procured by their agents. The shopping list included a hundred thousand bags of black pepper and thousands of pounds of other sorts of pepper; as much in the way of cloves, ginger and cinnamon as the ships could carry; 1000 barrels of nutmeg and 300 of mace; 3000 pounds of cassia wood (closely related to cinnamon); 6000 pounds of camphor; and the same amount of the ginger-like galingale ...”

“... In the great adventures of botanical discovery from the 17th to the 19th century, expertise about plants was often supplementary cargo in voyages whose main purpose was to find, chart and conquer new lands. You planted the flag and then you named the plants. Making an inventory of the world’s plants, learning where they grew (and where they could be made to grow), and figuring out what they were good for, were activities hugely dependent on the navies, armies and trading companies of the big imperial powers ...”

“... Now King David was old and stricken in years; and they covered him with clothes, but he gat no heat. Wherefore his servants said unto him, Let there be sought for my lord the king a young virgin: and let her stand before the king, and let her cherish him, and let her lie in thy bosom, that my lord the king may get heat. Her name was Abishag. She was of the tribe of Issachar, from the village of Shunem, and, for that reason, was known as a Shunammite ...”

“... In 1667, the Royal Society’s first historian described the early Restoration as ‘this Age of Experiments’. He was advertising the society’s new scientific programme and he was making a joke. One of the society’s most prominent members had designed and built a new sort of ship – a ‘Double-Bottomed’ vessel, a kind of catamaran – intended to require less draught, to sail faster and with a smaller crew than anything then at sea ...”

“... During​ the four centuries of its presence in British life, tea has made the transition from the exotically novel to the domestically ordinary, from a drug with possibly potent psychoactive powers to the mere ‘cup that cheers’, from a focus of social ritual to a casually taken and often solitary drink, from control by a quasi-state monopoly to a series of branded products largely dominated by multinational firms, from an artisanal to an industrial product ...”

“... From​ God’s point of view, the problem with the Tower of Babel was an excess both of hubris and of technological power. God had designed human beings to recognise the limits of what they could achieve, and here they were building a ‘tower whose top is in the heavens’. Not in my backyard, God thought, and pondered both the cause of man’s vaulting ambition and how He might put a permanent check on it ...”

“... Hedda Gabler​ ’s husband, Jørgen Tesman, is an academic historian – diligent, if a little plodding. He is researching a book which he hopes will make a splash, secure him a coveted professorship and support his wife’s taste for life in Oslo high society. When Tesman’s aunt asks him what the book will be about, he says it will deal with the domestic industries of Brabant in the Middle Ages ...”

“... In Tom Stoppard’s Jumpers, Dorothy Moore – a retired music-hall chanteuse and the wife of a moral philosopher called George Moore – is going dotty in her bedroom. The precipitating cause is a televised fight between the first two astronauts to land on the Moon about who gets to go back home on a damaged lunar ascent module that can carry only one ...”

“... Hydrogen and nitrogen combine only with difficulty. Since the reaction N2 + 3H2 2NH3 is reversible, you need just the right conditions to drive it forward to produce significant quantities of ammonia (NH3). If the temperature is too low, the formation of ammonia is favoured but the reaction goes slowly. If the temperature is too high, the reaction goes faster, but any ammonia produced tends to dissociate into its elements ...”

“... Physicians have historically walked a fine line between expertise and common sense, between innovation and tradition. If what they said to their patients was unintelligible, they ran the risk of being ignored. If, on the other hand, it was believed that doctors’ knowledge and advice were little different from common sense, what was the point of listening to them? What doctors know and what they can do have changed enormously over the past centuries ...”

“... America loves science. It has always loved science. As long ago as the 1830s, Tocqueville remarked on America’s love of science, and present-day surveys establish not only that 85 per cent of Americans believe that science ‘makes the world a better place’ but that an astonishing 80 per cent endorse Government support for scientific research even when no material benefits are in view ...”

“... Enrico Fermi​ is just the latest in a long line of ‘last men who knew everything’. A handful of recent biographies claim the title for their subjects, which include the Renaissance naturalist Athanasius Kircher (two books); the German polymath Gottfried Wilhelm Leibniz; the early 19th-century English physicist Thomas Young; and the 19th-century American palaeontologist Joseph Leidy ...”

“... The geeks at the Massachusetts Institute of Technology are fond of merry japes, locally known as ‘hacks’. One of the more memorable happened one night in October 1958 when an MIT fraternity had the idea of initiating new members by making them measure a bridge over the Charles River connecting the Cambridge campus with Boston. Crossing the bridge was often a wet, windy and unpleasant business and it was thought that students returning at night from downtown would like to know, by visible marks and with some precision, how far they still had to go ...”

“... Alexis St Martin was one of the 19th century’s most important scientific guinea pigs. In 1822, the illiterate young French-Canadian was working as a ‘voyageur’ for John Jacob Astor’s fur-trading company in northern Michigan. He was hanging out with a bunch of rowdies in the company store when a shotgun accidentally went off and he was hit below his left nipple ...”

“... When I was a boy – on this evidence, a miserable, maudlin sort of child – I used to kill time by calculating the value of a human life. Not the value of your soul or your contribution to civilisation or your lifetime earnings or your insurable value or the sums your heirs might realise in a wrongful death suit. I was interested in what a life’s worth when broken down into the stuff it’s made of, its bits and pieces, when to dust it hath returned ...”
