His own rays, with which he had doubled the solar spectrum, were altogether harmless and beneficent; but Radium denied its God — or, what was to Langley the same thing, denied the truths of his Science.
完全无害而且有益。 但是镭否认它的上帝——或者， 对兰利来说是一样的， 否认他的科学的真理。

Sunlight
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When it is blocked by the clouds or reflects off other objects, it is experienced as diffused light. The World Meteorological Organization uses the term "sunshine duration" to mean the cumulative time during which an area receives direct irradiance from the Sun of at least 120 watts per square meter.
