The scientists used the Hubble to figure out the direction of the star's travels and the distance from the galactic center, along with the star's mass, age and speed.

科学家们利用哈勃望远镜计算出该恒星行进的方向和离银河系中心的距离，连同他的质量、年龄和速度一起计算。

So, for two skaters of the same mass rotating at the same speed, the one with its mass more extended in space will have the greater angular momentum.

因此，对于以相同速度旋转的两个同质量选手来说，肢体在空间中更为外扩的那个选手将具备更大的角动量。

Since neutrinos have a tiny mass, the speed should be very close to the speed of light.

因为中微子的质量非常小，所以它的速度应该非常接近光速。

It involves the relationship of energy, mass and the speed of light, written as the letter c.

We give you a very rich table of constants that's got all kinds of things from the mass of the electron to the speed of light, and all this stuff to the requisite number of significant figures. And, in addition, you are allowed to take in one sheet of paper, 8 1/2 x 11 one sheet 8 1/2 x 11, you can write anything you want on it.

我们会给你一个很详实的常量表,将会涉及很多方面，从元素的电子,到光速，这些内容到有效数字的定量,还有，你们可以带来一张纸，纸的规格是，可以写任何你们想写的东西。

The difference in speed also means a difference in mass of 50%.

Elsewhere, mass speed-dating events are under way.

ECONOMIST: Singletons are getting some help finding a mate

And it seemed very fitting to talk about big data, insight acceleration and real time analytics in the very place where mass and speed of light got combined for posterity, more than a century ago.

FORBES: In-memory Computing and the Wisdom of the Telco Crowd

Einstein's special relativity theory that says energy equals mass times the speed of light squared underlies "pretty much everything in modern physics, " said John Ellis, a theoretical physicist at CERN who was not involved in the experiment.
