Hey, an article on the new Discover Mag talks about underground labs trying to detect dark matter. It mentions that the sensors have to be brought down to almost near absolute zero... I then realized that, even though I keep reading about things being put in extremely low temperatures, I have no clue how they do this.
How do they get materials to such low temperatures in labs? ... Any cooling agent I can think of (liquid N, etc.) is nowhere near absolute zero. My best guess is they get Dick Chaney to blow on the material in question.
