The "Moon App" thread got me wondering. Can any of you tell if a moon is waxing or waning just by looking at it? If I showed you a pic of a 3/4 moon, taken from Texas on some random unknown date, could you tell?

Never looked at it enough and paid attention to how it looks during different phases. I believe the color is supposed to be different

Left side black waxing right side black waning. Yep, very easy to tell if it is going to get bigger or smaller the next few nights.

In the northern hemisphere, if the left side of the Moon is dark then the light part is growing, and the Moon is referred to as waxing (moving toward a full moon). If the right side of the Moon is dark then the light part is shrinking, and the Moon is referred to as waning (past full and moving toward a new moon)

I understand the use of the word "waning", but where does the use of the word "waxing" come from in talking about a moon moving towards full? May be obvious after someone points it out, but I am curious about my own stupidity.

I'll throw a wrench in now for a bit of Trivia since you understand Waning from Waxing . Did you know that at all times even with a full moon you never see more than half the moon ?? And when you see what you think is a Half moon is really only a Quarter moon ? And when you understand that then can you guess why you always see the same side of the moon and never the backside ?

More than you ever wanted to know about this! Being a librarian, it was fun for me.
The moon, like many children, goes through phases. And, just as children’s phases have names (“terrible twos,” puberty, etc. ) the moon’s phases have names too, though we rarely use them nowadays.
Three terms are easy: When the moon is fully in shadow and not readily visible at all, it’s a “new moon”; when the whole surface facing the earth is alight, it’s a “full moon.” Just before and after “new” moon, we have a “crescent moon,” so called because only a small arc is visible.
It’s the between phases that have the unusual names.
As the surface of the moon becomes more lighted each day on the way to full, it’s “waxing.” “To wax” means to increase in size gradually, and used to be a frequent synonym for “grow,” according to the The Oxford English Dictionary. It was first used to describe the moon around 970, the OED says.
And as the surface becomes less lighted each day on the way back to “new,” it is “waning,” which, not surprisingly, means to decrease in size gradually. And, also not surprisingly, it appeared at the same time (and in the same place) as “waxing” did in reference to the moon. “Wax and wane” have always gone hand in hand, like “rise and fall.”
Then there’s the “gibbous moon,” when it’s more than a semicircle. “Gibbous” means “convex, rounded, protuberant.” The OED says “gibbous” was first applied to the moon in 1690, though it came into English more than 200 years earlier.
So we can have a “waxing gibbous moon” and a “waning gibbous moon,” though we see those terms outside of astronomical contexts only once in a blue moon.

You only see half the moon in reality because the other half is the backside which earth never sees' . That's because of the rotation of the moon and the backward path it takes in revelance to earths rotation . Otherwords the moon rotates same as earth does but the moon rotates the earth in a backward path . Therefore the same side of the moon is always present to earth . The only change you can see in the moons rotation is on a fullmoon night watch it when it comes up and notice how it looks then early next morn before moon sets in the west look and see if it looks exactly the same as it did when it rose the night before .
