Big is beautifulDNA. That was the message of post-second-world-war science. The model was the to build the first atom bombs. When hostilities ended, it continued with larger and larger particle accelerators, to probe matter at smaller and smaller scales—and bigger telescopes to do that probing at the largest scales imaginable. And, of course, there was the , which at its height in the mid-1960s absorbed more than 4% of America’s federal budget. After the Apollo Moon landings it went on to spawn the space shuttle and the International Space Station, as well as a programme of uncrewed missions to explore the nether reaches of the solar system.Nice for scientists, then. But so 20th century. For all of these projects were essentially about physics. By the late 1980s biologists were gaining confidence that the next century would belong to them. Biotechnology—the ability to tweak itself to make useful products—was taking wing. The number of biologists in training was booming. Some in the field were looking enviously at the physicists and asking themselves where they might queue up to dip their bread in the gravy.
