Re: More Damn "Moon's synchronism"

[Jim Green <JMGreen@sisna.com>]

Yes, John, I think that David would agree -- more or less -- and I=
 understand
this.  In the past David has said that there are something like mini-tidal
bulges which are superimposed on (under) the actual tides -- he hasn't=
 alleged
that this is true "on the average" but I think he will agree.   And I would=
 be
quite content if it were true.  I don't _hate_ the things after all.  The
problem here is that I don't know of any direct empirical data to support
this.  One can _postulate_ that this is so and make calculations as
geophysicists have done, but show me the damn bulges!!!=20
