But he should have remembered that at every successive dilution he lays aside or throws away ninety-nine hundredths of the fluid on which he is operating, and that, although he begins with a drop, he only prepares a millionth, billionth, trillionth, and similar fractions of it, all of which, added together, would constitute but a vastly minute portion of the drop with which he began.

Russian-born George Gamow, who had worked on the theory of nuclear synthesis in the 1930s and been involved in the Manhattan Project, conjectured that if an atomic bomb could, in a fraction of a millionth of a second, create elements detectable at the test site in the desert years later, then perhaps an explosion on a colossal scale could have produced the elements making up the universe as we know it.
