Hi all,

Which of the three basic laws of motion defined by Newton in his intro
to the Pricipia.. does the bulge on the opposite side to the moon
obey?

Action and reaction are equal and opposite?

In his book on astronomy for kids, Patrick Moore has sketched the
positions of the sun and moon at Spring and Neap Tides. The earth is
shown with bulges on both sides. There is no representation of the
(presumably smaller) bulge under the sun. Or was he just kee[ing it
simple?

Whichever answer you get for the last question, you are running up
against a paradox.

A great start for a budding astronomer this book. The Sun's tide is
coincident with the lunar "low tide" in this situation. Hence the
reason why the "low tide" at neap tide is higher than one at spring
tide.

I fail to see why virtually everything has to have some kind of
"weird" or unexplained reason for occurring, although I must admit,
your posts always encourage a flurry of responses!

cheers,

Paul K.
