Marty,

Right you are! Tell Donal to mark you up for One Point.

The Tides use the Moon Calender:^)
That is also the reason that Tide rides are possible.


I'm afraid that I can only award Marty 0.75 of a point.

I'm about to dissappear for a couple of days, so I'll explain when I get
back.

[hint] The sun has a much greater gravitational effect on the Earth than
the moon. So why does the moon seem to have a greater impact on the tides?

Well duh! Remember F=G*(m'*m")/(d^2), d is very much smaller in the earth moon case than the sun earth case.
IOW, it's because the moon is closer.

Give my point to Joe, he needs all the help he can get. ;-o

Cheers
Marty
