SUNDAY 4 APRIL
Palm Sunday 1971 94th day - 271 days to come
Made a board for PLANES using the plexiglass and posts
Claude gave me.
(cont. from 5/18) [5/18]
least 18 solutions to the NITTY GRITTY puzzle. I'll send his ad-
dress to Gini Scott. Frank offered to send me an extra
NITTY GRITTY he has, but I'll try to get one from Gini.
Looked at several books: GEOMETRIC DISSECTIONS by Harry Lindgren
(D. Van Nostrand Co., Inc. - 1964). Didn't seem very interesting.
THE NUMBER OF THINGS by Evans G. Valens (E.P. Dutton & Co. - 1964). Has
dissections & other recreations. THE PYTHAGOREAN PROPOSITION by
Elisha S. Loomis (Edwards Brothers, Ann Arbor, Mich. - 1940). A lot
of non-Euclidian proofs about triangles, etc. This book can be
purchased from The National Council of Teachers of Mathematics
{ 1201 Sixteenth St., N.W., Washington, D.C. 20036
They also put out Schaaf's A BIBLIOGRAPHY OF RECREATIONAL MATHEMATICS.
Looked at Martin's. It has AGOG, but no real description of it.
Martin had some correspondence about a game MAZIEX. He had
suggested that the inventor contact me. He thinks he saw the
game and then had to return it. Doesn't remember the details.
Frank mentioned a GAME he has signed a contract to do. Six
pegs are placed in a hex. Rubber bands of two different colors
are placed in turn between two pegs. First forced to form a
triangle, with vertices on pegs, of his color loses. Martin and I
both said it has already been done. Conway mentioned it
in a letter to Martin of which I have a copy.
Piet Hein sent Martin a model of a 3-D cube puzzle. 7 cubes
are sealed with a large transparant [transparent] cube big enough to hold
8 of the small cubes. Some faces are red and some white.
One objective is to get the outside faces red while the "hole"
is white, and there are others. Piet calls it MAGICUBE or
SEPTACUBE. Frank took the model and will contact Piet.
THE TURING GAME came up in the conversation. This is a
"game" where a person asks questions of a human and a computer.
He tries to fashion his questions so as to disover [discover] which is the
machine. Naturally, he doesn't see or hear them.
In another book, POPULAR SCIENTIFIC RECREATIONS (London-
Ward, Lock & Dowden - 1882), came across THE PACKER'S SECRET, which
was the same as TWELVE CIRCLES (see 3/10).
Showed Martin PIONERSKAJA IGROTEKA and he thinks he may be
able to get copies for himself and Frank.
They both mentioned a game PRODOMO (Prager, Capetown, South
Africa) which Laymen Allen is trying to peddle to all the game cos.
It is simply a set of double six DOMINOS with which a matching
game is played. The difference is that the number 1 above or
1 below, depending on the version played, is matched instead
of the same number. It goes "around the corner."
