By calculating the path between the lens and the sensor, the precise direction of a light ray can be reconstructed.

通过计算镜头和传感器之间的路径，可以重建一个具有精确方向的光线。

For certain wavelengths of light, routers along that path would accept signals coming in from only one direction and send them off in only one direction.

这条链路上的路由器对某种特定波长的光束，只接受从一个方向进入的信号，也只向一个方向发送这些信号。

The direction is up to each of us and the first steps we take each day will dictate which path we ultimately follow.

方向由我们每个人自己决定，而我们每天踏出的第一步都将指挥自己最终沿着怎样的路径走下去。

Speaking from my own experience, I believe a generative board is the key to unlocking a vision of the summit and the path to get there by harnessing and aligning organizational resources in the right direction.

Linksys Smart Wi-Fi Routers with Beamforming technology will precisely adjust, steer and monitor the direction and shape of the Wi-Fi signals in order to send data back and forth over the optimal path, resulting in up to two times the speed of routers without this technology in place.

But if flexibility-with-direction can simultaneously keep Indonesia together and put it on the path to a genuine democracy, la India, Wahid--and the world--will enjoy a momentous success.
