vision

It seems quite impossible to process separate sets of data with each eye; for example, putting a screen between your eyes, and trying to read 2 different books simultaneously. Is this a hard-wired limitation of our vision, or could we learn to preform such tasks? Evidently, other mammals and...

Here is a fascinating article on color vision by Paul Churchland, titled "Chimerical Colors: Some Phenomenological Predictions from Cognitive Neuroscience": http://web.gc.cuny.edu/cogsci/private/Churchland-chimeric-colors.pdf As you read it, you'll get to see colors you've never seen before...

Are drugstore (non-prescription) reading glasses harmful to your one's eyes?

This thread is the first part of what (I hope) will be a two-part series. In this thread I will accept ideas for a particular model I would like to build. In the second (proposed) part, I will collect the best ideas, and then present my working model for further scrutiny. I would like to build...

Why did humans not evolve the capacity to see infrared light? Are there animals that can? It seems like it would be a great evolutionary advantage to see a predator's body heat in the dead of night. Could it just be a mutation that never occurred? Is there some sort of physical limitation on the...

My dog Shiner Bark (see my avatar) is often intrigued by what's on television. Interestingly, he seems especially focused when animals appear on the screen, and shows a marked preference for mammals over reptiles or birds. I wasn't sure if he actually knew what he was looking at, or was just...

I play cello, and sometimes I have to read music for 2 hours straight. My music stand is positioned so that my music is almost exactly a meter from my eyes. Recently, when I've looked away from my sheet music, everything's been blurry. Originally, this only happened after about 2 hours of...

I was just curious what the consensus on this subject is from the viewpoint of people here who aren't christians?

I don't know how long this publication has been running, but I noticed that my local supermarket is selling a magazine called "Vision". From the cover it looks like it contains every woo you ever knew. I just wanted to let you know that I'm going to buy a copy and review it. Mainly I'm looking...

This thread is inspired by Randi's commentary of Oct. 6, 2006. He talked about the "visions" he had which had not come true. It should be quite obvious that too many of the "impossible coincidences" that paranormal believers come up with are the result of selective memory and retrofitting...

There are a lot of things relating to the human body that help with balance. I was doing some balance exercises yesterday, and realized how much vision plays a role. I stood on one leg with the other raised in front of me bent at the knee, and grabbed that knee with both hands. With eyes...

Correct me if I am mistaken, but the person referred to in the latest commentary piece called Lack of Vision, who says: presents themselves as an 'astrologer' who clearly knows that what he or she is doing is pure bunk. My feeling is that people like that deserve more contempt from us than...

Who is Bob Park - and why is an appeal to his authority regarded as a sufficient basis for decrying the 'Vision for Space Exploration'? Why is the 'Vision for Space Exploration' a 'faith-based' chimera but Hubble and Voyager aren't?

Can endothermic animals evolve heat vision like ssome insects and snakes have? Could IR cones go right along with the other cones in the eye?

I didn't much like George H. W. Bush (the current president's father). But there is one thing he said that I absolutely agree with. I don't like "the vision thing", either. I want a president, not a messiah!

Here's one that might be interesting if they went for the challenge: Russian X-Ray Vision Girl (the link can be slow) Anyone feeling motivated enough to contact her...? :D

Anyone seen this? http://www.ananova.com/news/story/sm_855907.html?menu=news.quirkies "Russian scientists have been unable to disprove a teenage girl who claims she has x-ray vision and can see inside human bodies. Doctors at Saransk's children hospital carried out exhaustive tests on...

Last year I had a vision which will come to pass. It will prove something which was not understood and the doors will be opened. Problem is it won't change anything, because the experience will still be outside yourselves, this I also saw. I will stay vauge on this, but you are talking to...

http://www.sciencedaily.com/releases/2003/10/031017073642.htm There could be a really cool science fiction story in this.

...would you consider this supernatural? I've heard of one health program that is, as claimed, based on some knowlege and exercises of anchient Sufies. While this program is supposed to make one healthy from all deseases, it is very effective in correcting vision. With simple eye-exercises one...
