Re: 1944: "The End of the Rainbow"

And, initially thought that a Billion Billion made a Trilllion, a Trillion Trillion made a Quadrillion, i.e.1k to the power 2 N (had I known of exponentials like that, at such a young age), which makes a handy Ultra-Long scale that works well with easily derived magnitudes of accuracy far further i...

The mean tropical year is measured at 365.24219 days, but is gradually getting smaller because the slowing of the earth's rotation is making the days longer. This means that in the long-run my system would be more accurate than either of those proposals. In discussions like this one the mean Gregor...

Re: Longest Name

IIRC, if you divide the diameter of a sphere into N equal parts, and cut the sphere perpendicular to it, the resulting slices will surprisingly have equal area (the long ones will be thin, and the short ones will be wide, and it happens to compensate exactly).
