A new electronic microscope now allows atoms to be seen clearly:

I want one.

Wow

That is incredible !
Pretty soon they will have one strong enough to measure the IQ of my neighbours ! (if they have one) or may be that is just too small

Her's the very first picture! (the atom is slightly left of centre due to tracking misalignment).

Didnt you learn anything in physics / chemistry ?? From what I remember these must be atoms of a dense solid, but I maybe wrong !!

They look like buttocks to me. :-|

I think this is a filmstrip from a porn movie! :o

No material is completely dense, nor are atoms.

Where did you get that from? I could not find it on the link and what kind of atoms are they?

They are from solid silicon.

"completely dense" is not a phrase that makes sense scientifically.

The link posted in the lead post had a link to the lab which did the work.

I wanted to see a picture so hunted around their site to find one, it took a while!

I think it was in their "news" section.

The atoms are of silicon.

How do we know they aren't fake if no-one else has this magic machine.

Do you remember the story about the guy that claimed he could see creatures on the moon? (long ago)

I suppose that is true. Density like every other quality is relative. I was attempting to illustrate that matter contains a lot of empty space between the atoms and within the atoms there is a lot of empty space between the particles.

I suppose it could be argued that 'completely dense' or 'absolutely dense' would be a state when all the matter in the universe was in a singularity just before the Big Bang.

But why would anyone want to establish such an elaborate con trick?
