But instead of taking a single path, light can bend around the object in one of two, or four different routes, thus doubling or quadrupling the amount of information scientists receive.

但是光并非只走一条路径，而是可以从两个或四个不同路径中的一个绕过物体，这样科学家可以获得两倍或四倍的信息量。

Thus, our planet as a whole can grow more complex because thesun pours heat and light onto it, and the greater entropy associatedwith the sun’s nuclear fusion more than rebalances the scales.

所以，地球作为一个整体，是可以变得更加复杂的，因为太阳将光和热传递给它；相比地球自身的变化，地球的熵与太阳的核聚变关系更为密切。

MOST cells are transparent—in other words, they are not very good at reflecting or absorbing light. To look at them under a microscope thus requires trickery.

大多数细胞都是透明的——换句话说，它们都不易于反射或吸收光线，所以在显微镜下观察细胞需要一些技巧，但这些技巧往往会杀死细胞，而且即使某些方法能够观察到活细胞，也只能看到其切片图，而非三维全貌。

These give out a continuous spectrum of light, and thus affect a wide range of frequencies that are of interest to astronomers.

Users can simply mount the entire flashlight and charger as a unit by doorways and entryways to hazardous locations, thus providing a highly convenient and fully charged portable light source whenever it is needed.

ENGADGET: Explosion-proof flashlight could be the first to outlive its owner

These results thus shed light on why, in a series of clinical trials conducted last autumn, leptin treatment did not prove uniformly effective (let alone miraculous).
