I'm old. I get confused. OK?

comment Why are “irrational numbers” not named “nonrational numbers”?
Because to do so would be irrational.

Ask a dentist and he'll tell you it's the gunky buildup on your teeth.

comment Is there name for arithmetic mean divided by RMS average?
CV appears to relate mean to standard deviation, and I'm taking the ratio of mean and RMS average, which is not quite the same thing.

comment Is there a reasoning behind the depiction of the numbers as they are $\{1$, $2$, $3$, $4$, $5$, $6$, $7$, $8$, $9\}$?
I was always given to understand that the Babylonians had something to do with it. But I see Wikipedia lays most of the "blame" on the Hindu-Arabic numeral system. (According to that article using zero came fairly late in the evolution of the system.)

comment Need algorithm to take “max” of scores, but with “quality” weighting
@JoshuaShaneLiberman -- I'm not sure I understand the objectives completely, which is part of the problem. But there's an issue with the quality metrics I probably didn't explain very well -- I'll do that.

comment How to add or multiply decimal numbers?
The common way of adding decimal numbers is to use "excess-6" arithmetic, where 6 is added if the digit exceeds 9. There are various clever ways to do this, some more "clever" than they should be, but since the operation tends to be highly optimized the cleverness is usually merited.

comment Sheffer stroke the most important advance in logic?
It's worth pointing out that, in the parallel world of digital logic design, the NAND gate is considered to be the "universal" logical element -- any digital device you want to build can be built fron NAND gates. (And, in fact, this was often done.) I can imagine that if NAND gates had been invented fairly late in the development of digital electronics (rather than being just about the first thing invented) they would have been considered quite magical.
