I speak to a great many student groups and I am often struck by
how few of them appreciate the difference between one million, one
billion and one trillion. (In the name of fairness, the same is
true of many adults). 
Perhaps, it is because the three figures are all large
numbers that most people don’t think there is an appreciable
difference. Perhaps, it is because the words – million, billion,
and trillion – the rhyme; or maybe it’s just because they’re
dumb—or have had poor teachers. I really don’t know.
One way I have tried to convey the difference between the numbers is by explaining the figures in a different way. To wit:
One million seconds was 12 days ago; One billion seconds was roughly 30 years ago; One trillion seconds was approximately 30,000 years ago – 28,000 B.C.!
My point with the analogy is that one trillion of anything is a really BIG number, and it is much, much different than one billion. This analogy is important because on January 17, 2006 the Wellcome Sanger Institute announced it had archived it’s one billionth DNA sequence. It was an impressive accomplishment.
Well, today, Wired magazine reported that the prominent genetics institute sequenced its trillionth base of DNA. This is a one thousand-fold improvement in just over two years. (cont.)
