I am kind of getting used to been treated as if I were superman. I am not. I can't do all the science before the science is made. So, for now, let's deal with black and white. That, in turn, will help other scientists to take the next step towards understanding the retina in full.
And how about, after we do the black and white, you do the color thing?

You earned your parole. Because your answer addressed the actual issue I was raising, the conversation can continue. Your next problem is dealing with dimensionality. The retina is actually five dimensional. It has two spatial dimensions, the brightness, and two color dimensions. If you need to understand how two color dimensions map to three colors, play around with a TV that uses component video, pull out the red and blue wires and see what the picture looks like. Then play around with different combinations of the red and blue wires in different plugs. The green wire is critical and must always be connected to the correct plug. Hearing is actually not that much simpler. Basically, you will need to extend your theory to deal with orthogonal sets of orderings... If you manage that, it'll become interesting again. =P -- E T F N H E D E D Powers are not rights. ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/18883996-f0d58d57 Modify Your Subscription: https://www.listbox.com/member/?&; d2 Powered by Listbox: http://www.listbox.com ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-c97d2393 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-2484a968 Powered by Listbox: http://www.listbox.com
