There is an ambiguity in the claim, FWIW. Is "1/4 the size" 1/4 the diameter, or 1/4 the area?

I think the following would be "more comprehensible," meaning more people who read it would understand ... only 10 nerve cells are involved in viewing a dime held at arm's length.

I was born with 20/400 vision in my right eye so my left eye naturally corrected and I once had 20/18 vision. I can shoot rifles (left handed) and billiards very well as I am right handed, and if I look at objects at just the right angle I get what seems like 3D vision. My one eye sees an object and at the same time my other eye sees the blur of an adjoining object. Hard to describe but unique, I am sure!

LOL!!! Typical 3AM thoughts for me are definitely not appropriate to post here!

“viewing a dime held at arm’s length” — perfect. No ambiguity there. That’s the old standby explanation.

I’m nitpicking, of course. Otherwise it’s a fine, and very interesting, article. It really illustrates how little we know about the wonders of vision (which rather surprised me).

wow i never heard that before :)

How is that possible???
This was THE radio guy in Chicago 1960s, a live wire!!!
He’s from NY maybe a cousin of yours?
A fun and wild guy!!! A Fungus Amugus was his big one but Ulgywoman played too.
Regarded by some as the greatest disc jockey of all time!
https://en.wikipedia.org/wiki/Dick_Biondi

He was hired in 1958 by WKBW 1520 AM in Buffalo; at WKBW if conditions were right, Biondi could be heard in Europe.[3] After a dispute at WKBW, Biondi jokingly
described his boss’s car on the air, said where he would be driving, and asked his listeners to throw rocks at it. Someone did as Biondi asked and he was fired the next day.

My father, an engineer, had told me when I was a kid that pretty much anything in the universe could be expressed mathematically.

The older I get the more I realize how right he was.

I read up on it :)

So at 51, that means my 30 year old nephews are going to ask me one day “was Guns n Roses from the 70s?”

They were formed in the mid 80s.

Ugly wife but she sure can cook lol

Thank you for the excellent information.

It’s hard to explain, but I feel color without touching an object. Just as you hear different tones and pitches to recognize someone’s voice, my consciousness feels the vibration associated with various colors. It gets confusing though as the material or surface of the object that has the color also resonates a frequency.

Years ago I was with two geologists who were comparing specimens they collected. I went to pick one of the rocks up and jumped back, saying ouch, that one is hot before I ever touched it. They looked at me like I was crazy.

I went on to “feel” each one without touching the rocks, noting each one had a different feel.

They put all the specimens in a large flat box and put a towel over it, asking me to tell them where each rock was in the box. It was easy.

A couple of months later one of the geologists invited me to go along with him to a geologist’s meeting. It but several hours away, but he insisted, so I went.

Upon arriving, I found that I was their meeting speaker for the evening. They had 30 to 40 styrofoam cups upside down on the lab table with sequential numbers on each and various specimens held inside by tissue paper. They asked me to describe the feel of each sample.

I had never done this previously and it was a total set up.

I went through each sample describing what I felt as the attendees took notes by cup number. Then I sorted them by groups that felt similar.

Allow me to add that to me, they were just rocks as I have zero geologist knowledge.

There was one cup that I set way off to the side from all the other groups as it didn’t even feel like a rock in the cup. (It was an old Indian paint pot used to grind and mix paints)

The group president then flipped over each cup describing what specimen was in each one while the group compared it to their notes of my comments.

I was astonished at the accuracy of the groupings. I feel frequencies resonating from most objects and people.

I understand you are making a pun.

I actually wasn't making a pun, but thanks for the insight (now that was a pun).
