Bubbles Rising in Water

[arcFlash]

I've used this technique and it works great. I came up from around 100 feet many times while just watching a tiny bubble and the computer profile was spot on. I call it "shiny" because I pick the smallest and reflecting the most light. My computer is a spaz and it doesn't have the fidelity I want or at least I don't feel like it does when I have to go up a long way without visual ques. I make a new shiny if I lose the first by swiping my hand though exhaust thus pulling a cavitation trail into eyesight.

It's easy in blue water and gets more difficult as vis declines.

Next, Cyclotomic polynomials where the product is over all nth primitive roots of unity.

Just kidding, That's off topic.
