Originally I wanted to post this thread in the Physics and Math forum but decided that it was more a philosophical question than a math of physics question even though it seems to me to be a fundamental of both. [Physics and Philosophy] Essentially I wished to discuss how important the notion of zero is to us humans and our thought processes. I have come to beleive that one of the most primary concerns of our intellects is the need to make comparisons and would contend that comparison is only available to us when we make the assumption of zero difference as our first premise. That as a default within our minds we are very well aware of nothing or the value of nothing being zero. Care to discuss? Please Register or Log in to view the hidden image!
