Cold water in cold weather
-
Do this simple little test to show how the body reacts to temperature. Get three glasses. Line them up. But ice cold water in one on the edge, room temperature water in the one in the middle and hot water [don't burn yourself] in the one on the right. Put one finger from each hand into the other glasses [i.e. the cold water and the hot water] and leave there for about 30 seconds... then put both finger in the middle glass??? Notice anything... You "read" the temperature as being cold with the finger that was in the cold water and hot with the finger that was in the hot water but they will equalise after about 15 to twenty seconds. There was some weird biological explanation for this when I was in school but I haven't done biology in about 9 years so bugger me if I know the answer. Basically we react to temperatures by reading them dependant on the ambient temperature around the part of our body that the temperature is being applied to... or so I've been led to believe. I could be completely wrong here so if I am could somebody please let me know.

(2) A low-paid slave labourer who is forced to weekly (or sometimes more often) lecture on esoteric topics to spoiled rich kids (whose mommies and daddies pay all of their tuition) who would rather be skateboarding or surfing, either of which not in the classroom. This slave labourer is also forced to grade the students' homeworks and exams, as if the graduate student in question did not already have enough to do. At least, that would be what a cynic would say. I don't know about other UC Irvine depts., but in Physics you must pass the TSE (Test of Spoken English) satisfactorily otherwise you are not allowed contact with the students, and all you can do is grade if you want the Department to pay you anything. :) BTW, who is this person you mentioned earlier, maybe I do know them...
