History of subject[edit]

When was it discovered? Infovarius (talk) 11:46, 3 November 2009 (UTC) In Hydrodynamics, it was first discovered in 1969, by Prof. Moffatt in DAMTP. —Preceding unsigned comment added by 131.111.17.71 (talk) 22:43, 7 November 2009 (UTC)[reply]

Components of the equations need to be defined[edit]

It looks like much of the information for this page was taken from a textbook. As such, it presumes that the reader is familiar with the meaning and notation of the variables being used in the equations given. That is not likely the case for your average Wikipedia reader, rendering the information useless. Someone familiar with the subject manner should break out the variables and define them individually.
