Now I am struggling with some very simple mechanical problems. This brings back some fond memories from university. We considered mechanical engineers a bunch of ... ehrm ... simple guys who drink too much. Maybe because we could not keep up with them. We have tried very hard, believe me. A famous adage of the time originated from one of our mechanical engineering teachers. He was struggling an hour with a simple slope problem, and after we helped a bit, he came out with a result, and said: "When you encounter a serious problem in mechanics, leave it to a qualified mechanical engineer." Well, I know that this kind of discrimination is a huge mistake. This kind of thinking has lead to deaths of millions in nazi concentration camps. What I have noticed is that questions in the area of mechanics got answered more hardly in the homework forums than others. I find it nearly as devastating as WWII. There might be a number of reasons for this, but the one I have came up with says that this is due to the discrimination people in this area receive.
