TWSB: Hydrogen: Putting the ‘H’ in “Holy Crap, the Universe is So Empty”

Crap!

So I found this page the other day and bookmarked it for a TWSB post…the page was a demonstration of how ‘empty’ we all are at the atomic level. On the current replacement page, the author states, “The page had a picture of a proton that was one thousand pixels wide, and a little electron that was only one pixel wide, and they were separated by fifty million pixels of empty space – I worked it out that that was eleven miles if your monitor displayed 72 pixels per inch, not uncommon at the time. You could try to scroll between them and it would take a long time. It was kind of neat.”

It was neat. But because of browser issues and issues surrounding the model of the atom the author used (he used the model Bohr developed), he took down the page.

In its place, though, he offers a similar study of scale and emptiness: the solar system.

To me, his atomic demonstration is more powerful since its fascinating how “solid” beings such as ourselves are composed of so much space, but the solar system demo is pretty snazzy, too.

Related: I’m assuming some of you Moscow people who stumble across this have taken the Moscow-Pullman trail…have you seen the little solar system distance exercise set up by a bunch of elementary school kids? It’s pretty cool. Pay attention at the head of the Moscow end of the trail to see the pics.

This Week’s Science Blog: Sliding scale fun!

Here’s a short and sweet TWSB for you all, since I spent all afternoon at Sean’s and just rediscovered this while using the airports’ free internet. You’ve probably already seen this already, but it’s still awesome.
