Just before Sir Isaac Newton died, he described how humbled he felt by the thought that he had glimpsed only a fraction of the potential of the great scientific revolution he had helped to launch: "I seem to have been only like a boy playing on the seashore and diverting myself in now and then finding a smoother pebble or prettier shell than ordinary, while the great ocean of truth lay all undiscovered before me."
Three centuries later, that great ocean of truth is not so mysterious. According to the theoretical physicist Professor Michio Kaku of the City College of New York, we are entering an empowered new era: "We have unlocked the secrets of matter. We have unravelled the molecule of life, DNA. And we have created a form of artificial intelligence, the computer. We are making the historic transition from the age of scientific discovery to the age of scientific mastery in which we will be able to manipulate and mould nature almost to our wishes."
Among the technologies he believes will change our lives in the coming decades are cars that drive themselves, lab-grown human organs, 3D television, robots that can perform household tasks, eye glasses that double as home-entertainment centres, the exploitation of genes that alter human ageing and the possibility of invisibility and forms of teleportation.
"We will have the power to animate the inanimate, the power to create life itself," says Prof Kaku. "We will have the power of gods. But will we also have the wisdom of Solomon?"
In a new BBC4 series called Visions of the Future, Prof Kaku talks to today's pioneers about how we are moving from being passive observers of nature to its choreographers. Here are their remarkable speculations about how the scientific and technological revolution will transform life and society in the 21st century.
