If there is one thing scientists have to hear , it is that the game is over . Raised on the belief of an endless voyage of discovery , they recoil （畏縮） from the suggestion that most of the best things have already been located . If they have , today's scientists can hope to contribute no more than a few grace notes to the symphony of science .

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 . The shock of realizing that science might be over came to him , he says , when he was talking to Oxford mathematician and physicist Sir Roger Penrose .

The End of Science provoked a wave of denunciation （譴責(zé)） in the United States last year . “The reaction has been one of complete shock and disbelief,” Mr . Horgan says .

The real question is whether any remaining unsolved problems , of which there are plenty , lend themselves to universal solutions . If they do not , then the focus of scientific discovery is already narrowing . Since the triumphs of the 1960s — the genetic code , plate tectonics （板塊構(gòu)造說(shuō) ） , and the microwave background radiation that went a long way towards proving the Big Bang — genuine scientific revolutions have been scarce . More scientists are now alive , spending more money on research , than ever . Yet most of the great discoveries of the 19th and 20th centuries were made before the appearance of state sponsorship , when the scientific enterprise was a fraction of its present size .

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 science and engineering can go on for ever . I hope we get a cure for cancer , and for mental disease , though there are few real signs of progress . ”
