A book to be published in Britain this week，The End of Science，argues persuasively that this is the case. Its author，John Horgan，is a senior writer for Scientific American magazine，who has interviewed many of today’s leading scientists and science philosophers.

If they do not，then the focus of scientific discovery is already narrowing. Since the triumphs of the 1960s—the genetic code，plate tectonics（板块构造说），and the microwave background radiation that went a long way towards proving the Big Bang—genuine scientific revolutions have been scarce.

Were the scientists who made these discoveries brighter than today’s？That seems unlikely. A far more reasonable explanation is that fundamental science has already entered a period of diminished returns.“Look，don’t get me wrong，”says Mr. Horgan.“There are lots of important things still to study，and applied
