Just how small is a nanometer?

 

 

Liked this guys analogy with the aircraft carrier... anyone got a better one?

circumference of george bush's brain?

 

he actually, made a mistake in the film, a nanometer is a billionth of a meter, not a millionth. a millionth is a micrometer.

 

most of us here have a pretty good sense of scale as some of us deal with similar sizes daily. especially those in the optics field.

in the film he says a millionth of a millimeter, not meter...

 

does that still make him wrong?

No he got it right. A millionth of a millimeter([math]10^{-6}mm[/math]) is the same as a billionth of a meter ([math]10^{-9}m[/math]) and that is a nanometer.
