Even people on Earth are exposed to cosmic radiation, but the amount is negligible.

大型太阳风暴产生时，不在地球大气保护中的太空人就会暴露在致命剂量的辐射下，搭乘商用客机飞行在高纬区的人们也会暴露在较高的辐射中，即使是在地球上的人们也是暴露在宇宙辐射中，只不过这些辐射量已经是微不足道的。

At that time the main danger had come from the Polemarch, and Bean wrote an anonymous letter to a couple of opinion leaders on Earth, Locke and Demosthenes, urging them to get all the Battle School children back to Earth so they couldn't be seized or killed by the Polemarch's forces in the League War.

在那个时候，最主要的危险是来自官员的，而豆子给地球上的两名对立意见的领导者，洛克和德摩斯梯尼写了一封信，建议他们掌握所有战斗学校的孩子带他们回地球，这样他们就不会被国家官僚在联盟战争中所控制或谋杀。

The supposed advantage was that any observer with a decimal chronometer and a view of the sun's height above the horizon would then know instantly where on the planet he was. With 100 decimal degrees (or "gons" as they became known) to a right-angle, and the distance from the pole to the equator being almost exactly 10,000 kilometres, 1 km along the surface subtends an angle of one centigon (a hundredth of a decimal degree) at the centre of the Earth.

人们认为这种表的优势在于：任何人只要有这样一块十进制表，再能看到地平线以上太阳的高度，就会立刻知道他在地球上的位置。100个十进制度（更为流行的称法叫作&百分度&）就是一个直角，从极点到赤道的距离几乎就是10000公里；这两点就使得地球表面的一公里的地心夹角恰巧是1centigon （即1百分度的百分之一）。
