The Pliss Constant....
Aug. 30th, 2007 02:55 pmEvery so often, someone or something from my past will pop into my head for no apparent reason.
Today it was "the Pliss constant". It was devised by someone at my high school -- I think it was Joe Pliss -- who used it as an elegant "fudge factor" on a physics exam. The word spread about it. Someone else, who was in the same class, later tried to use it in a college-level physics course, and got full credit for the problem. One of the explanations I've heard was "It's so new it's not in the most recent CRC Handbook of Chemistry & Physics."
Leafing through the CRC book -- this book is huge! -- I came across something called Beer's Law. After snickering for a few seconds, I read what it was. It has something to do with absorption of light in a liquid. Here's what the Wikipedia has to say about it.
