Quantum mechanics is a highly successful theory: it supplies methods for accurately calculating the results of diverse experiments, especially with minute particles.
量子力学是一种非常成功的理论：它提供了精确计算各种实验结果的方法，特别适用于微小粒子方面。

And this is the familiar result from ordinary mechanics, where you're not worrying about something like entropy for a whole collection ofparticles.
在普通力学中，如果不关注大量粒子的熵，诸如此类的物理量的话，这就是我们通常见到的结果。

In the bizarre world of quantum mechanics, however, subatomic particles can exist in several states at once.
