Cabe,

Nice article.  You did a great job explaining exactly what was taking place and how, questions that were immediately raised as I watched the video,questions like what molecule were they using, what environment could be so stable and what is the background that is void of any other visible molecules.  

And thanks for including the "How it was made" link as it fleshed out the people behind the video and made me appreciate it even more.  And also answered the question of how they were moving the molecules around.

Fascinating, really.

I've watched the video twice now and it's still hard for me to comprehend the fact that I'm really looking at atoms. I suppose it's because I don't really know how a scanning tunneling microcope works. I wish I could hear the actual sounds the atom makes, instead of the music.

Carbon Monoxide Atoms?

It's been a while since my last chemistry class, but isn't carbon monoxide a molecule?  I know this is very nit-picky, but let's try to get at least the technical stuff correct.

The video and technology is amazing.

Yes, carbon monoxide is definitely a molecule, so you are correct there. It is one of the more stable molecules, in chemical terms, non-dissosiated, meaning thet unlike salt, NaCl, which comes apart very readily in water , CO stays tightly bonded even when it attaches to something else. That is part of the reason that it is toxic, which is because it binds stably to the iron in our blood, preventing it from releasing any oxygen. Because of this tight bond the molecule is fairly smooth, and so it looks round in the video.

Besides, a movie titled "a boy and his molecule" just would not sound as cool.

They could have called it "Adam and his molecule"

Great video, Cabe. These microscopes, and what they can "see", are amazing and mind-boggling. More science fiction come alive.

I look forward to when we can see even deeper, with our own eyes. Seeing a nucleus, clearly, will be like our landing on the Moon. And, I hope to live to see it.
