　　It is easy to lose patience with science today.The questions are pressing:How dangerous is air pollution?What about low-level radiation?When will that horrible earthquake strike California?And why can’t we predict weather better?But the evidence is often described as “uncertain”,forcing scientists to base their points of view almost as much on intuition(直觉)as on science.

　　When historians and philosophers of science listen to these questions,some conclude that science may not be able to solve all these problems any time soon.The unknowns can grow into riddles that are impossible to solve.Because of the unstable and changing state of the earth’s atmosphere,for example,scientists have struggled for centuries to predict the weather with precision(精确) but failed.

　　The case is different for scientists of astronomy.For example,they think that the gravitational force of a nearby space vehicle,though tiny,is able to change the path of a much larger planet if the vehicle spends enough time close to it.With the aid of Newton’s laws of gravitational attraction,ground controllers can predict the path of a planetary probe(探测仪)—or satellite—with incredible accuracy.They do this by calculating the gravitational force from each of the passing planets until the probe speeds beyond the edge of the solar system.A much more difficult task is to calculate what happens when two or three times of such force pulls on the probe at the same time.Such procedures can,of course,be very difficult,but for experiments,they are effective.
