Dear Ms. Clader,

You quote Edward Lorentz:

"Chaos: When the present determines the future, but the approximate present does not determine the approximate future."

The Wikipedia entry for Chaos Theory has the quote:

"Chaos: When the present determines the future, but the approximate present does not approximately determine the future."

http://en.wikipedia.org/wiki/Chaos_theory

I do not know which is correct, not having the source at hand, but it seems to me that second version better expresses the implications.

Regards,
Roy
