This ratio also means that an unpowered hang-glider flying at a constant speed moves 15 metres forward for every one metre it descends.

这个比例也意味着一架无动力悬挂式滑翔机以恒定速率飞行时高度每下降1米，可以向前滑翔15米。

And the relationship that he put forth is that the momentum is equal to Planck's constant times nu divided by the speed of light, or it's often more useful for us to think about it in terms of wavelength.

爱因斯坦提出的关系式是,动量等于普朗克常数,乘以υ除以光速，或者用波长来表示,通常更容易让我们想明白。

And the rotation has to be both continuous and at a constant speed, which for the LZT is 8.5 revolutions per minute.

FORBES: Liquid Mirror Telescope Technology Finally Going Mainstream

And in the science of optics, the fact that the speed of light is constant in a vacuum is taken for granted.

FORBES: Why Marco Rubio Needs To Know That The Earth Is Billions Of Years Old

Because it is far more efficient to unwind the spring at a constant speed, rather than stopping and starting it, this provides enough energy to run the radio for an hour.
