Full moon through a dirty window. It’s blueish hue reminds me of those old songs, moon spoon, June, tunes of the past.

A glowing cold ball in the sky. Full now, but no longer linked to lunatics and howling wolves. Perhaps the fluorescent glow from sodium lights has drowned out its flooding influence.

But the tides still turn under its gravity, pulled upwards, the sea rises with the moon above it, while on the opposite side of the Earth the sea is held less firmly and slacken into another bulge. That is why there are two high tides and low tides a day.

And the Moon is tidally locked with Earth, so one side always faces us now. The Moon may be the result of a cataclysmic impact when a small planet struck Earth a glancing blow and lifted matter from Earth into the sky. The matter from the collision coalesced into the Moon and its orbit around Earth began. Now it is gradually moving away, a few centimeters a year. As it orbits Earth it is gradually slowing our spin. We used to make one rotation of the planet in around Twenty three hours. Now we have slowed to twenty four.

Moon. So much to learn.
