The story begins, in a sense, in classrooms around the world, where students are taught that the rate of decay of a specific radioactive material is a constant.

这个事情要从世界各地的教室里说起，在那里学生学习到特定核素的衰变速率是恒定的。

"Everyone thought it must be due to experimental mistakes, because we're all brought up to believe that decay rates are constant," Sturrock said.

“每个人都认为这是实验误差造成的，因为我们从接触物理开始就相信衰变速率是常量。”Sturrock说。

But if physicists at Stanford and Purdue are correct in their findings, the whole theory of constant radioactive decay rates could be thrown out the door.

Physicists have long held the view that the rate of breakdown - or decay - for any given radioactive substance is constant.
