Wed, 16 Mar 2022 00:32:59 +0000http://jblblog.wordpress.com/?p=2060#comment-924The alt text (“FYI: If you get curious and start trying to calculate the time adjustment function that minimizes the gap between the most-used and least-used digit (for a representative sample of common cook times) without altering any time by more than 10%, and someone asks you what you are doing, it is easier to just lie.”) is exactly where I was for several weeks last winter!

Wed, 16 Mar 2022 00:30:39 +0000http://jblblog.wordpress.com/?p=2049#comment-922I don’t have the book at hand at the moment, but as I remember, he doesn’t make a case for base 8 in particular over other bases — just the idea that, by introducing arithmetic in a different base, you can help students understand what is really going on when they do arithmetic. (I presume this was also the motivation behind introducing other bases in New Math.)

Sun, 13 Mar 2022 13:58:27 +0000http://jblblog.wordpress.com/?p=2049#comment-921I wonder why he chose base 8, and not, say, base 6 (which I would be naturally inclined towards, since the structure resembles ours more closely), or base 4, (which is the first big enough to be interesting for a contrast in arithmetic, and which I am teaching high school students just now, albeit with the wrong alphabet, to set up my little mini-introduction to axiomatic arithmetic).
