不久前,一颗天文卫星引发了一场不大不小的恐慌。据称这颗在太空遨游了12年之久的报废卫星残骸将会撞击地球,最大的碎片重量达400公斤。然而最终,它平静地落入了孟加拉湾,没有对地球造成任何伤害。这颗X射线天文卫星正是以伟大的实验物理学家伦琴命名的。还是不久前,我在旅行途中看到一篇关于伦琴的文章,突然想到应该适当纪念一下。虽然今年已是X射线发现116周年,不是一个整数周年,但是这种心结一旦撩起来,就再也放不下了。
Not long ago, an astronomy satellite triggered a modest panic. Allegedly this scrapped satellite payloads that have spent 12 years in space will hit the Earth with a maximum weight of 400 kg. In the end, however, it calmly fell into the Bay of Bengal without any harm to the Earth. The X-ray astronomy satellite is named after the great experimental physicist Roentgen. Not long ago, I saw an article on Roentgen while traveling, and I suddenly thought that it should be properly commemorated. Although this year is the 116th anniversary of X-ray discovery, it is not an integer year anniversary. However, once the knot has been lifted, it can no longer be put on.
