stochastic, I really don't think you need to apologize. You wanted a real-life example of why the product of two negative numbers produces a positive number. After I gave you an example using torque and rotation, I was basically called a sewer rat by arildno. I guess that we are sewer rats for needing to have practical applications for mathematics; if so, then I guess that sewer rats are more practical than mathematicians.
You insisted upon having a practical application for negative numbers, after I gave you one, we were called sewer rats, and then the thread was closed because you "insist on denigrating people". Maybe chroot should have taken arildno's post into consideration, I thought that his was pretty denigrating. I tend to think that chroot is biased, considering that he locked a perfectly healthy thread with one of his reasons being that you were being denigrating, when others were just as denigrating.
I am making somewhat of a deal about this incident because this should be a forum, where people can discuss issues, even when they don't agree. Disagreement is a great fuel for educational conversations. I don't like the idea that an administrator can close a thread any time he wants just because he doesn't like how the discussion is going. This makes me leery about getting involved in any more threads, for fear of being banned because I don't agree with the democratic majority.
Lastly, I do not know any engineering, physics, or mathematics professors that would have engaged into insulting others simply because they do not agree with their views. Real professionals discuss issues with facts, not with opinions, and that is why I tend to believe that many of those involved in these forums are teenagers or first-year college students.
