Perceiving feedback

Posted by Matzaball50@aol.com John, A very nice post, thank you, and not to nit pick, but I think you might be mistaken in one instance here. >>When we assert that F=ma, we are claiming (metaphorically) I do not believe this is a metaphor.

Perceiving feedback

Posted by Matzaball50@aol.com Martin, I'll take a shot at this, even though I'm not entirely convinced I fully understand what type of comments you are seeking.

Mental model creation process

Posted by Matzaball50@aol.com Folks, There is life after Hume. :-) May I suggest the epistemology of one Karl Popper. http://www.eeng.dcu.ie/~tkpw/ IMO, he does Hume, Locke, Kant, and Russell proud.
