ABSOLUTELY NOT a waste of time, Chuck. It's stimulating and it's also true. For years I've tried to figure out something about that: do we even have the same brain process when we see? We only get strings of electrical impulses from our sense organs, conveyed to our brains. What if brains are not all organized alike? What if one brain interprets those impulses that hit the visual center in some way entirely unlike another's brain? I can barely express what I'm talking about, but suppose the brain "sees" information from the senses in some unique way? If we could go inside each other's heads, maybe we wouldn't even recognize things the other person was seeing as visual, or hearing as audible. Ultimately we may be isolated in our interpretations and not even realize it. -- Just a weird thought, Joe --- On Wed, 12/2/09, Chuck Hards <chuck.hards@gmail.com> wrote: From: Chuck Hards <chuck.hards@gmail.com> Subject: Re: [Utah-astronomy] M51 reprocessed To: "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Date: Wednesday, December 2, 2009, 6:44 PM Yes, I'm going to re-emphasize this. David and I have not been communicating. Cameras and associated hardware and software are capable of recording what the general population sees. I have never disputed that. I fully agree with David. I have been trying to communicate the concept that those colors exist only in our minds and are entirely subjective. It's quite apparent that I have failed to make the concept clear. It's times like these that I wish I were a better communicator. Sorry to have wasted everyone's time, and mine apparently. _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com
