What Happens to Superscript Over the Phone
"'It takes about 150 attoseconds for an electron to circle the nucleus of an atom. An attosecond is 10-18 seconds long, or, expressed in another way: an attosecond is related to a second as a second is related to the age of the universe,' said Johan Mauritsson of Lund University in Sweden."
I assume that's supposed to be 10 to the -18th power. Either that, or the entire universe has only been around for one-tenth, or possibly one-eighteenth, of a second. Catch it before they edit the article!
(Also: We can measure attoseconds! Science is freakin' amazing.)
