"Something had to be grown in rotation with corn." Scott Jackson, professor of plant genetics at Purdue University.
VOA: standard.2010.02.01
Actually, the view of vectors we take nowadays is that vectors are associated with a pair of numbers which, on the rotation of axes, transform like this.
实际上,今天我们讲矢量所用的观点是,矢量是和一组坐标值相对应的,在坐标轴旋转的过程中像这样变换
The idea that he had was, if you go from me to you, with a clockwise rotation, you go from you to me by a counterclockwise rotation.
他的方法是这样的,如果这个矢量从这转到那是顺时针方向,那么这个矢量转回来就是逆时针方向
