A very pleasing irony of writing this thoughtless and classless, “We’re all doomed” blog is that it has resulted in my being introduced to thoughtful and classy heroes like Tony Gardiner, mathematical stars who have been working tirelessly for decades that we not be doomed. The most recent introduction is to Edward Barbeau, a star of Canadian mathematics education. Tony Guttmann, AKA Mr. Very Big, alerted me to a long comment Ed contributed to a maths-ed discussion, on gifted education. Ed has kindly permitted me to reproduce his great comment here.

We have the bigger projects (AC, ITE, SD) in the works, plus an FOI appeal to do, plus 2000 words for a lefty magazine due in a couple weeks. We’re kinda busy. But, we’ll try to keep the general posts ticking along. This one is some fun, plus some history and a couple of puzzles.
One of the all-time great maths scenes is Abbott and Costello’s famous bit, where Lou Costello proves that 7 x 13 = 28:
Ken Clements is an interesting character, of whom and by whom we’ve been reading a lot of late. We plan to write about Clements in the near future, but for now we’ll just post an article by Clements on a really interesting character.

We have written about Tony Gardiner and excerpted from his writings a number of times: here, here, here, here and here. We will post an entire article by Tony in a day or so, but we are first posting the problems contained within the article. Unlike the “problem” here, the problems below are genuinely presented by Tony to puzzle over, and are only loosely tied to the text of the article. Have fun.

It’s amazing the things one finds while scavenging.
OK, hands up who thought there was ever gonna be a second NotCH?
We’re not really a puzzle sort of guy, and base ten puzzles in particular tend to bore us. So, this is unlikely to be a regular thing. Still, the following question came up in some non-puzzle reading (upon which we plan to post very soon), and it struck us as interesting, for a couple reasons. And, a request to you smart loudmouths who comment frequently:
Please don’t give the game away until non-regular commenters have had time to think and/or comment.
Start by writing out a few terms of the standard doubling sequence:
1, 2, 4, 8, 16, 32, 64, etc. Continue reading “NotCH 2: A Digits Puzzle”
More or less by accident, this post is the beginning of a new series: Not Crap Here.
A couple of people have suggested that we could occasionally include Dr. Jekyll material on this blog. You know, helpful stuff. It’s a decent idea, if our current thoughts weren’t so influenced by misanthropic disgust and murderous rage. Still, we’ve received two specific requests for the same old Jekyll material,* and which entailed some digging. Having finally dug, we’ve decided to post the material here, for whomever is interested. Whether or not there will ever be a NotCH 2 is anybody’s guess.
