The Rational Optimist_ How Prosperity Evolves - Matt Ridley [120]
Likewise, of the four men who made the biggest advances in the steam engine – Thomas Newcomen, James Watt, Richard Trevithick and George Stephenson – three were utterly ignorant of scientific theories, and historians disagree about whether the fourth, Watt, derived any influence from theory at all. It was they who made possible the theories of the vacuum and the laws of thermodynamics, not vice versa. Denis Papin, their Frenchborn forerunner, was a scientist, but he got his insights from building an engine rather than the other way round. Heroic efforts by eighteenth-century scientists to prove that Newcomen got his chief insights from Papin’s theories proved wholly unsuccessful.
Throughout the industrial revolution, scientists were the beneficiaries of new technology, much more than they were the benefactors. Even at the famous Lunar Society, where the industrial entrepreneur Josiah Wedgwood liked to rub shoulders with natural philosophers like Erasmus Darwin and Joseph Priestley, he got his best idea – the ‘rose-turning’ lathe – from a fellow factory owner, Matthew Boulton. And although Benjamin Franklin’s fertile mind generated many inventions based on principles, from lightning rods to bifocal spectacles, none led to the founding of industries.
So top-down science played little part in the early years of the industrial revolution. In any case, English scientific virtuosity dries up at the key moment. Can you name a single great English scientific discovery of the first half of the eighteenth century? It was an especially barren time for natural philosophers, even in Britain. No, the industrial revolution was not sparked by some deus ex machina of scientific inspiration. Later science did contribute to the gathering pace of invention and the line between discovery and invention became increasingly blurred as the nineteenth century wore on. Thus only when the principles of electrical transmission were understood could the telegraph be perfected; once coal miners understood the succession of geological strata, they knew better where to sink new mines; once benzene’s ring structure was known, manufacturers could design dyes rather than serendipitously stumble on them. And so on. But even most of this was, in Joel Mokyr’s words, ‘a semidirected, groping, bumbling process of trial and error by clever, dexterous professionals with a vague but gradually clearer notion of the processes at work’. It is a stretch to call most of this science, however. It is what happens today in the garages and cafés of Silicon Valley, but not in the labs of Stanford University.
The twentieth century, too, is replete with technologies that owe just as little to philosophy and to universities as the cotton industry did: flight, solid-state electronics, software. To which scientist would you give credit for the mobile telephone or the search engine or the blog? In a lecture on serendipity in 2007, the Cambridge physicist Sir Richard Friend, citing the example of high-temperature superconductivity – which was stumbled upon in the 1980s and explained afterwards – admitted that even today scientists’ job is really to come along and explain the empirical findings of technological tinkerers after they have discovered something.
The inescapable fact is that most technological change comes from attempts to improve existing technology. It happens on the shop floor among apprentices and mechanicals, or in the workplace among the users of computer programs, and only rarely as a result of the application and transfer of knowledge from the ivory towers of the
