Thank you for that link. I found the full article even more interesting.

It explains one problem I couldn’t solve, viz how to get from chancy to shanty: spell shanty “chanty”. Must be some variant spelling.

The persons in the dialogues are often mathematically ignorant.

How is 6 the maximum number of regions? Maybe I’m missing something, but can’t a Star of David be formed by two triangles? And doesn’t it create 8 regions (one in the center, six by the points of the star, and one for the outside)?

Hi, In general the powers of n can be encoded by 1 / (10^k – n).
k being the number of digits of the largest element of the sequence to
be encoded.
The first 11 terms of Fibonacci sequence can be encoded by 1 / 998999.
In general : 1 / 99…8999…

In my kitchen the tabletop extends to infinity in every direction. (Which could explain the rent I pay.)

Can the triangles touch the edge of the table, thus separating the outside region into multiple regions?

There’s an old Feynman and 1/243 story that dates back to the Los Alamos days.

I recently got a note that reminded me about numbers like these and led me to start telling everyone about 1001000/997002999. I’m still a bit mystified by this number: on the one hand, its decimal is periodic, but on the other, there’s a sequence in which different amounts are always being carried, which destroys the natural periodicity of the last digits of the sequence.

Polynomial, evaluated at a power of 10 large enough to show enough terms of the sequence that you can recognise it.

The Fibonacci numbers aren’t defined as the values of a polynomial, of course; they’re defined by a recurrence, and the polynomial arises from that.

Here is a good source of alternative maps of the world: http://flourish.org/upsidedownmap/

I put the same request in Google+ a few days ago and got a few suggestions: https://plus.google.com/u/0/108840294486623374565/posts/QCyXJpufpDW.

I found this quote in a newspaper the other day that I have put on my classroom wall:

“Mi padre decía: ‘El talento no es nada, hay demasiado talento, hay talento por todas partes; trabajar, trabaja, mátate a trabajar’.”
(Geraldine Chaplin, actriz)

“My father said: ‘Talent is nothing, there’s too much talent, there’s talent everywhere, work, work, kill yourself working.’”

I have a lot of non-math things on my walls. (Well, we moved a year ago, and they’re not back up yet…) One is a map of the world with the South Pole at top. I love how it confuses people. Is that mathematical?

What about mathematically-inspired artwork?
