It refers not to the person feeling like they are at absolute zero but the air feeling to the person as if the air were absolute zero. To see how this is possible, consider the rate at which heat would be lost from a person's body if the air were still but it were at absolute zero. There would be some finite rate at which heat would be conducted away from the person. Now consider that if air is moving, it is possible that heat might be transferred from the person at an even higher rate. Thus, the feeling of cold moving air is even colder than still air at absolute zero. -- edp (Eric Postpischil) "Always mount a scratch monkey." edp@jareth.enet.dec.com
