Re: [ATM] TDE (That Darned Edge)
Well, it's unclear what is meant by 1/16" square. It could mean 1/16 of a square inch, or it could be a square that is 1/16 of an inch on each side. People can and do mean either one of the two. The first one is indeed a square that is 1/4 of an inch on each side; the second one is 1/256 of a square inch.

no one did. The piece of paper to look at under the blue light should be
1/16 square inch. That would be a 1/4 inch square.
I thought someone would find the size so small they would have to check for
errors.

See! It is so small that not one person noticed that the paper needed to be
cut in half two more times to get to 1/16" square! Use the paper to record
your zone readings so as to save a tree.

I told you I was not a whiz at math. I used a red light and it looked
smaller.

A typical piece of paper for your printer is .004" thick. Cut a 1 inch
square out of a piece of printer paper. Cut the 1" square half. Take one of
the halves and cut it in half. Take one of those halves and cut it in half
and cut one of those in half, keep one and discard all of the rest of the
paper. You now have a 1/16" to the side square .004" thick. Hold that in
some tweezers and inspect it carefully under a bright blue high resolution
light. You are looking at the same quantity of paper as the quantity of
glass you need to remove from the sphere to make it a parabola. You may now
discard that piece of paper. However you may want to put it by your figuring
work position as a reminder of what you are trying to do.
If I am wrong on this there are 100 people who are going to jump me. And
they should.
Short time in figuring sessions can do very much work compared to the work
necessary.
