Just How Small Is an Atom? [Video]

In this animated offering from TEDEducation (a branch of the awesome organization behind TED Talks), we’re treated to a peek inside the atom and some entertaining models to give us a sense of scale.

Jason Fitzpatrick is warranty-voiding DIYer and all around geek. When he's not documenting mods and hacks he's doing his best to make sure a generation of college students graduate knowing they should put their pants on one leg at a time and go on to greatness, just like Bruce Dickinson. You can follow him on if you'd like.

    This Ted-Ex lesson, while correct and clear in matters of relative size, however perpetuates the widespread but incorrect, outdated and misleading picture that electrons orbit the nucleus as a miniature planetary system.

    …They didn’t even do anything with the elementary particles. I would have loved to see that!

    That was interesting and informative. Somebody questioned the proposed notion that “electrons orbit the nucleus as a miniature planetary system.” I think the video did address that by saying they orbit about the edge of the atom. A discussion of elementary particles would have been an added interest, but I can’t imagine how they would detail that. It was also interesting to note the density of the atom was so huge. That was new and different. The whole video was informative.

    What would the gravitational pull of the box be?
