Just like a ball at the top of a hill, the molecules always move towards a lower energy state if they can, and that's just what they'll do.

就像山顶上的球一样，如果可以的话， 分子总是向较低的能量状态移动， 而这正是它们会做的。

Instead, they're stuck in a loosely bound high-energy state and are dying to move to a more stable lower energy state, which means releasing a lot of pent-up energy in the process.

相反，它们处于一种松散约束的高能量状态，并且极其容易向更稳定的低能量状态转变，这就意味着在这个过程中它们会释放大量封存的能量。

So they store up extra water in the years that we have excess water to provide for the lower basin states in the years that we don't have as much water.

所以他们在我们有多余水的年份储存额外的水，以在我们没有那么多水的年份为较低的盆地州提供。

It's possible that somewhere, out in the dark, dead Universe, for whatever reason, after a gazillion years, some small bit of space will quantumly jostled, and drop down to that next lower state, the true vacuum.

很有可能在黑暗、死寂的宇宙的某个地方，不知出于什么原因，过了无数年之后，一小块空间会发生量子碰撞，并下降到下一个更低的能量状态，即真正的真空。

One of the biggest concerns of the agreement both then and now was the expanding population in the southwest, particularly in southern California, and the resulting increased demand over time for water in the lower Basin states.

无论是当时还是现在，该协议最大的担忧之一都是西南部人口的增加，尤其是南加州，以及随着时间的推移，盆地下游各州对水的需求也会随之增加。

Reluctantly they yielded to the demand for federal courts, consenting at first only to a supreme court to review cases heard in lower state courts and finally to such additional inferior courts as Congress might deem necessary.

他们不情愿地屈服于联邦法院的要求，起初只同意最高法院审查下级州法院审理的案件， 最后同意国会可能认为必要的其他下级法院。
