REGARDING TIDES AND THE MOON'S INFLUENCE ON THE HUMAN SKULL

The tides at a given place in the Earth's oceans occur about an hour later each day. Since the Moon passes overhead about an hour later each day, it was long suspected that the Moon was associated with tides. Newton's Law of Gravitation provided a quantitative understanding of that association.

Differential Forces
Consider a water molecule in the ocean. It is attracted gravitationally by the Earth, but it also experiences a much smaller gravitational attraction from the Moon (much smaller because the Moon is much further away and much less massive than the Earth). But this gravitational attraction of the Moon is not limited to the water molecules; in fact, the Moon exerts a gravitational force on every object on and in the Earth. Tides occur because the Earth is a body of finite extent and these forces are not uniform: some parts of the Earth are closer to the Moon than other parts, and since the gravitational force drops off as the inverse square distance, those parts experience a larger gravitational tug from the Moon than parts that are further away.


I hesitate to even make mention of this but....
I've noticed for some time now, that during certain times of the day the top of my head begins to rise towards the heavens and becomes a perfectly formed cone. Does this phenomenon occur to any other MOABS or is it unique to me alone?
