Very interesting pictures...

That's very cool. I'd love to have an electron microscope... I'd look at everything in my house.

Neat!

This one looks like it came from some NASA probe on an alien planet.

I really wish I had some 3D glasses right about now

Yeah, I'm wishing I hadn't got rid of my old Grand Funk Shinin' On album!

That does look like an amazing canyon! To think some of our most beloved music is somehow encoded in that canyon!

Yup.

Just drag a rock through it and we be jammin'!

See those ragged pits covered in dirt? That's unbeatable fidelity right there.

What's even more impressive is that a diamond can resolve such small details (IIRC .01 microns in size).

A CD's smallest pit, IIRC, is .8 microns.

I think I read somewhere that someone had created a microscopic record and used an atomic force microscope to "play" it.

It's not as easy as that. There's a lot of surface prep that goes into it before you can even look at a sample. That said, I do have an SEM at work and have been guilty of putting random stuff into it for fun.

A really good optical microscope can actually get reasonable resolution at 1000x, although your depth of focus will suck.

Spray some "LP treatment liquids" on it and see what happens.

You can get relatively cheap STM microscopes that fit into the palm of your hand but the images are not as sharp and do not have perspective.

Groovy!
