Gorgeous, high-magnification sand photos

I’ve often wondered what happens to the grains after they grind together
till there is nothing left. Just a bunch of molecules at the bottom of the beach?


#3

At what point do tiny shells and other small objects recognizable in and of themselves transition from being “small things mixed in with sand” to “components of the sand itself?”


#4

Isn’t that clay?


#5

That one grain of sand looks alot like a worn down shell, but I’m sure that is just coincidence.

There wouldn’t have been enough time to erode that small, since the earth is only 6 to 10 thousand years old.

God sure works in mysterious ways :expressionless:

No. That would be silt. Silt is the product of physical weathering. Clay is the product of chemical weathering.

This has been your geopedantry moment of the day.


#7

Is there a geopedantry archive? because this is the first entry I’ve read, and I rather enjoyed it…


#8

Surf is sort of like a giant rock tumbler, and shells are pretty soft, so shell to sand grain is likely to be not just geological-scale short, but human-scale short. Weeks maybe? Not that I don’t appreciate the point you’re going for, but I thought I’d go for some geopedantry too.

More likely, the photos are part of the Atheist Anti-Religion Assembly (AAA) and their effort to undermine the Creation Truths.

These “sand grains” are obviously man-made, created by someone sanding and polishing full-sized shells down to grain size.

Don’t let these non-religious nuts pull the wool over your eyes.

So, I guess this isn’t the same Gary Greenberg that used to smoke weed with David Brooks?

Strange, because this really sounds like something a pothead would do.

“Have you ever really looked at sand, man, I mean really looked at it?”


#11

The collection on Greenberg’s own website is better than the random blogger first mentioned here.

These are beautiful, thanks for posting.


#12

given enough time they might ultimately become sandstone


#13

Nope, this Gary lives in Hawaii. Pot essayist Gary is a therapist in Connecticut.


#14

I would love to see the process he uses to create these photographs.


#15

Come to Maui during the Institute for Astronomy Open House in the fall. Dr. Greenberg generally has a lab open, with the stereoscopic microscopes and cameras he uses for his work. He’s a pretty social guy and would probably enjoy talking shop.
