Comment on A Calendar Puzzle by Anthony C. Lanni

One die is going to be the tens column, one is going to be the ones.
You need a zero, one and two on each die to account for the tens column in your rolls.

One die will have a 3, 4, and 5; the other will have a 6, 7, and 8. The 6 can be reversed to act as a 9.

so, first die: 0 1 2 3 4 5
second die: 0 1 2 6 7 8

From this combination you can get every number from 01 to 31. You can also get spurious numbers like 00, 58, 71, etc. The rules don’t say you can’t do that, though.

Wow. Ramanujan formulae truly can move people.

16 can’t work because 5 plots go to the daughter but the remaining 11 plots can’t be divided onto 11 peasant evenly..

Thanks John for your comment. My wife – the techie in the house – installed math jax which is rendering with java script. I’m not surprised that it doesn’t render in google reader.

When I read your blog post in Google Reader, I see TeX source code, not an equation. Visiting your page directly, I see the equation properly rendered.

I see this all the time when people first use a plug-in to automatically render TeX. It can be fixed, but apparently the default configuration doesn’t work. Unfortunately I can’t tell you how to fix it because I haven’t used the software.

Managed to watch the above mentioned movie, titled "unbowed" on a noisy aeroplane via a 7 inch monitor at 2am en route to India. I enjoyed it thoroughly in spite of the circumstances.

Apparently Boyer’s Law is more apt, according to Kennedy (Amer. Math. Monthly 1972). He states in his article:
BOYER’S LAW. Mathematical formulas and theorems are usually not named after their original discoverers.

It is perhaps interesting to note that this is probably a rare instance of a law whose statement confirms its own validity!
