Apologies for the light blogging. I’m thinking of changing-up my style a little and doing shorter posts more often, including ones that just link to interesting stuff on the web with brief commentary.
In that spirit, this is just cool. It’s a web page depicting a hydrogen atom scaled up so that the electron is one pixel. Its distance to the proton (a big blue circle) is to scale also – such that the web page, on most monitors, is 11 miles wide, all of it black save for the proton, the electron, and the column of explanatory text. Thus illustrating just how much empty space there is in the everyday atoms that make up the supposedly solid everyday things around us.
Note that they are only showing the radius; if this were a helium aton, the other electron would probably be 11 miles from the nucleus in the other direction; so most atoms at this scale are at least 22 miles wide.
