To paraphrase the warning car companies engrave on side-view mirrors - objects in the mirror are farther away than they appear.
我引用汽车公司刻在后视镜上面的话——镜子里面的东西总是比看起来的要远。
We see objects in a mirror, because a mirror, when hit by particles of light called photons, reflects the photons back to us and some reach, and enter, our eyes.
我们之所以看到镜子中的物体，是因为当镜子被称为光子的光的微粒击中后将光子反射回来，一部分光子则到达并进入我们的眼睛。
In the Top viewport, select all of the spoke objects and mirror them using object Snap 'Cen'.
在俯视图中，选择所有的轮辐，以中心为参照点镜像。
