In order to open obviously the human brain intelligence, even achieves the sudden enlightenment condition, we should cause "the energetic temperature" to drop "the zero absolute temperature".

The temperature scale that turns out to be well—defined and ends up giving us the concept of an absolute zero is the ideal gas thermometer.

We looked at pressure change before, actually, in discussing the third law, the fact that the entropy goes to zero as the absolute temperature goes to zero for a pure, perfect crystal.
