we could do that either quantum mechanically or classically solve for that.
我们既可以利用量子力学也,可以利用经典力学来做这个事。
"If you had a tuning fork and got it cold enough, maybe that could behave quantum mechanically," he said.
“如果你用一个音叉，让它足够冷，也许可以表现出量子力学，”他说。

“如果你用一个音叉，让它足够冷，也许可以表现出量子力学，”他说。
And if you treat this properly, quantum mechanically, for the translations, there's actually a magnitude of the number is similar.
如果用量子力学方法来处理，对于平动的状态数，的确也是这么个量级。
