Hi, I love learning, and from time to time I run into questions that google, local education institutes, and general information hunting at the library comes up fruitless. So to you physics forum I turn! About me - Father, husband, geek, techie, cancer survivor x2, retired soldier/IT professional geek. About my questions - Mostly materials science questions and a few high energy physics questions. Oh yes, as well as the ever burning question... why is it 42?!?!?
