光给我们提供了在很大范围内探测和操控自然的工具。我们可以利用它捕捉和冷却原子以获得接近绝对零度 ,加热物质到超新星环境下的极限条件。电磁谱范围从较长的无线电波、红外线和可见光 ,延伸到较短的紫外线、X光和伽马射线。在某些波段 ,我们有办法控制和利用光束 :例如通过 Light gives us the tools to detect and manipulate nature over a large area. We can use it to capture and cool atoms to get near absolute zero, heating the material to the supernova environment of the limit conditions. The electromagnetic spectrum extends from longer radio waves, infrared and visible light, to shorter ultraviolet, x-ray and gamma rays. In some bands, we have ways to control and utilize light: for example, through
