From < Computing1 the future> 摘自《经济学人》 Mar2 23rd 2006
WHAT makes a scientific revolution? (1)Thomas Kuhn famously described it as a “paradigm shift”—the change that takes place when one idea is overtaken by another, usually through the replacement3 over time of the generation of scientists who adhered to an old idea with another that cleaves4 to a new one.These revolutions can be triggered by technological5 breakthroughs, such as the construction of the first telescope (which overthrew6 the Aristotelian idea that heavenly bodies are perfect and unchanging) and by conceptual breakthroughs such as the invention of calculus7 (which allowed the laws of motion to be formulated). (2)This week, a group of computer scientists claimed that developments in their subject will trigger a scientific revolution of similar proportions in the next 15 years.
