Even the most advanced thermometer on Earth, one invented by a man named Dwight Adams, cannot measure down to absolute zero. It can only measure to .0009 degrees Kelvin. As Dr. Adams once told me, this is because “cooling to a lower temperature is a process of lowering entropy.” Entropy is a measure of the disorder or randomness of a system. [i.e. a measure of motion.] Because the entropy is approaching 0 regardless of the state of the material providing the cooling, the amount by which you can decrease the entropy (and the temperature) in one step gets smaller and smaller. Perhaps the analogy of walking across a room to the opposite wall will help. If you cut your steps in half each time, you would have to take an infinite number of steps to reach the other side of the room.

Basically, lowering entropy is lowering motion, randomness, chaos, and thereby heat. In other words, there must be no love in San Francisco today. It is that cold.

Tactical Advantage director Daren Rabinovitch, also in San Francisco today, advises us that the perfect movie to watch on an afternoon approaching 0 Kelvin is Three Women by Robert Altman.
