Every two days we create as much data as we did from the beginning of mankind until 2003!

How Much is an Exabyte?
1 Exabyte = 1000 Petabytes = could hold approximately500,000,000,000,000 pages of standard printed text
It takes one tree to produce 94,200 pages of a book
Thus it will take 530,785,562,327 trees to store an Exabyte of data
In 2005, there were 400,246,300,201 trees on Earth
We can store .75 Exabytes of data using all the trees on the entire planet.

How many trees does it take to print out an Exabyte?

Feynman Diagrams
Feynman: “What I am really try to do is bring birth to clarity, which is really a half-assedly thought-out-pictorial semi-vision thing. I would see the jiggle-jiggle-jiggle or the wiggle of the path. Even now when I talk about the influence functional, I see the coupling and I take this turn - like as if there was a big bag of stuff - and try to collect it in away and to push it. It's all visual. It's hard to explain.”
James Gleick, The Life and Science of Richard Feynman, Vintage Books, New York, 1992.

The Need for High Resolution Visualization
Lower Resolution High Resolution
“…the data show for the first time how detailed transport and chemistry effects can influence the mixing of reactive scalars. It may be advantageous to incorporate these effects within molecular mixing models. It is worth noting that at present it is impossible to obtain this type of information any other way than by using the type of highly resolved simulation performed here.”Jacqueline Chen, Sandia National Laboratories

Antony van Leeuwenhoek (1632-1723)
. . . my work, which I've done for a long time, was not pursued in order to gain the praise I now enjoy, but chiefly from a craving after knowledge, which I notice resides in me more than in most other men. And therewithal, whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that all ingenious people might be informed thereof.
Antony van Leeuwenhoek. Letter of June 12, 1716
