Human knowledge is collective, distributed across the population. It has built on itself for centuries, becoming vast and increasingly specialized. Most of us are ignorant about the fundamental principles of the civilization that supports us, happily utilizing the latest—or even the most basic—technology without having the slightest idea of why it works or how it came to be. If you had to go back to absolute basics, like some sort of postcataclysmic Robinson Crusoe, would you know how to re-create an internal combustion engine, put together a microscope, get metals out of rock, or even how to produce food for yourself?
Lewis Dartnell proposes that the key to preserving civilization in an apocalyptic scenario is to provide a quickstart guide, adapted to cataclysmic circumstances. The Knowledge describes many of the modern technologies we employ, but first it explains the fundamentals upon which they are built. Every piece of technology rests on an enormous support network of other technologies, all interlinked and mutually dependent. You can’t hope to build a radio, for example, without understanding how to acquire the raw materials it requires, as well as generate the electricity needed to run it. But Dartnell doesn’t just provide specific information for starting over; he also reveals the greatest invention of them all—the phenomenal knowledge-generating machine that is the scientific method itself.
The Knowledge is a brilliantly original guide to the fundamentals of science and how it built our modern world.
Trevor Norton, who has been compared to Gerard Durrell and Bill Bryson, weaves an entertaining history with a seductive mix of eureka moments, disasters and dirty tricks.
Although inventors were often scientists or engineers, many were not: Samuel Morse (Morse code) was a painter, Lazlow Biro (ballpoint) was a sculptor and hypnotist, and Logie Baird (TV) sold boot polish. The inventor of the automatic telephone switchboard was an undertaker who believed the operator was diverting his calls to rival morticians so he decided to make all telephone operators redundant.
Inventors are mavericks indifferent to conventional wisdom so critics were dismissive of even their best ideas: radio had 'no future,' electric light was 'an idiotic idea' and X-rays were 'a hoax.' Even so, the state of New Jersey moved to ban X-ray opera glasses. The head of the General Post Office rejected telephones as unneccesary as there were 'plenty of small boys to run messages.'
Inventomania is a magical place where eccentrics are always in season and their stories are usually unbelievable - but rest assured, nothing has been invented.
