Are you talking about morning stars and evening stars?  Those are candlestick terms used to predict the movement of a stock price.  A morning star signifies the end of a down movement and vice versa for a evening star.  www.candlestickforum.com has all you need to know about candlesticks.  \n\nI use candlesticks to get a good visual of the stock price.  But I'd be careful about using them as the only source of stock trading considerations.

I'm assuming you saw these expressions in a text devoted to economic growth; in such a context, k star could mean the steady-state level of capital for an economy, k tilde (squiggly line) could mean capital per effective unit of labor; this is only an assumption, nonetheless; I can't be sure in the context of which model you saw these expressions. To be sure, look at the book/paper from which you obtained these expressions, and check how these variables are defined; I can say, though, that a star superscript associated to a variable generally denotes an optimal level.

Mostly, this is a bit of poetic license by the author of the song.\n\nHowever, it is founded in how you go about refining gold ore.\n\nWhen you're refining or working gold, the more pure the gold, the more desirable.  This is expressed in the karet figure - 10k, 18k, 24k, for instance.  \n\nSo, presumably, if it is God refining the gold, it will be as pure as it possibly can be, and therefore of the highest value.

FIRST OFF...WHAT THE HECK IS THIS QUESTION DOING IN THE MATHEMATICS CATEGORY?!\n\ngold represents several things in this poem...\nfirst green is gold...(could be: first money (green) was based on gold, or could be that when trees sprout fresh (INNOCENT) leaves from branches they look tan/gold.)\nas autumn turns leaves to gold, they die and fall off...\nlight (as in golden sunlight) will always fall each day...\n\nbasically, it is saying that although gold (innocence) is the most precious commodity, you cannot hold onto it because it is always bound to go away...
