That's called conservation of angular momentum.

这称为「角动量守恒定律」。

Caffeine seemed to be in violation of the laws of thermodynamics.

咖啡因作用机制，似乎不符合能量守恒与转换定律。

To creat a life, there had to be a death. The balance of world had to be repaid.

创造出一个生命就一个生命。世界守恒被尊重。

Like, people knew about conservation of mass, but somehow caloric had to be massless yet occupy volume.

比如，人们知道质量守恒，但不知何故，卡路里是无质量，但却占据体积。

That's called the conservation of angular momentum.

- 这就是所谓角动量守恒。

When the momentum is conserved, that means it has to stay constant.

当动量守恒时， 这意味着保持不变。

23. The reason why rockets work in space is the conservation of momentum.

23. 火箭在太空中工作原因是动量守恒。

Its existence is inferred from the conservation of energy.

推断存在是为了能量守恒。

This is because of a principle called conservation of angular momentum.

这是因为称为角动量守恒原理。

In your collaborations, always remember that " credit" is not a conserved quantity.

在您合作中，请始终记住“信用” 不是守恒量。

And when kinetic energy isn’t conserved, that’s an inelastic collision.

当动能不守恒时， 这就是非弹性碰撞。

This is because the law of conservation of mass says, broadly, that however you use it, you cannot destroy the stuff.

这是因为根据质量守恒定律，大体上而言，无论怎么用，你都消灭不了水这一物质。

But even though those numbers of nucleons add up, remember: Mass and energy are equivalent.

但即便核中数字被加总了，还是要记得：质能守恒。

Even on the upper east side, the laws of physics dictate that what goes up must come down.

即使在上东区，能量守恒定律决定了风水轮流转道理。

And when kinetic energy isn't conserved, that's an inelastic collision.

The first rule, which deals with conservation of charge, is something we’ve actually already discussed.

第一条规则涉及电荷守恒， 我们实际上已经讨论过了。

Torricelli’s theorem uses conservation of energy to find the velocity of fluid flowing from a small spout in a container.

托里切利定理使用能量守恒来计算从容器中小喷口流出流体速度。

Like potentially turning you in to a giant green rage monster that doesn't obey the laws of conservation of matter.

就像有可能把你变成一个不遵守物质守恒定律巨大绿色愤怒怪物。

Conservation of information isn’t just an arbitrary rule, but a mathematical necessity, upon which much of modern science is built.

信息守恒不仅是一个武断规则，而且是一种数学上然性， 许多现代科学都建立在之上。
