The Crystalline is not merely minerals, rather it is the vibration of perfect ordering, it is the frequency of perfection, and in vibrational terms what you refer to as Impeccability.

这些晶体不仅是矿物质，而是在于它有完美次序的振动，完美的频率，这振动就是你们所意指的“无罪性Impeccability”。

Last time we reach the third law which is telling us that we can't quite get to zero degrees Kelvin .but that as the temperature approaches zero degrees Kelvin, the absolute entropy of a pure substance in perfect crystalline form is zero.

上次课我们得到了热力学第三定律,这个定律告诉我们我们无法,达到0K的温度,但是在我们接近绝对零度的过程中，以完美晶体形式存在的纯物质的绝对熵,也趋向于零。
