玻尔根据原子的结构，和在电子轨道间的跳跃情况，就能预见光的波长。

Bohr was able to predict the wave lengths of the light from the makeup of the atom, and the jump from electron orbit to electron orbit.

适量的能量撞击电子时，电子将吸收能量并跳跃至高能级轨道。

Hit it with just the right amount of energy, and it will absorb it, and the electron will jump up to a higher energy level.

我儿子就是通过这样学习走路，讲话，读书，写字，筑墙（垒高拼装玩具），拼接火车轨道（玩具），跳跃，奔跑以及骑单车。

That is how he learned to walk, speak, read, write, build lego walls, set up train tracks, jump, run, and pedal.
