CRUX GOES ON-LINE!!

[ Editor: promotional sentences omitted and the boxed price table
  re-wrapped as plain text. ]

As of September 3 1996, Crux Mathematicorum, the Canadian Mathematical
Society's internationally respected problem solving journal is
available on-line at

    http://camel.math.ca/CMS/CRUX/

Published eight times per year (February, March, April, May, September,
October, November, December), individual subscribers now have the
option of both receiving hardcopy and accessing CRUX on-line or
subscribing to on-line access only (see below for current subscription
charges).

To demonstrate its new service, the CMS is offering open access to some
past issues of Crux Mathematicorum to everyone.

Comments and feedback from CMS members and CRUX subscribers are
strongly encouraged.  Please send email to crux@cms.math.ca or contact
the CMS directly.

For 1997, the hardcopy subscription price is $54.00 CDN ($27.00 for CMS
members) for Canadian shipping addresses and $54.00 US ($27.00 US for

Did you know that there is a publication devoted to computer recreations &
'mathemagic'?

ABOUT REC

REC - which is short for Recreational & Educational Computing - is now in
its 11th year (first half of 1997).

REC is about puzzles & teasers, programming (BASIC, some Pascal, a little
C), math, letters, graphics, fractals, challenges, recreation, reviews,
word-play, humor, tips, solutions, and more. One exclusive is the
editor's own concept of "Mathemagical Black Holes" (similar to
attractors). These range from digit-delving to word-play to graphics.

Many ideas or programs are reader-generated or reader-contributed from
virtually every continent. The spirit is playful, with an admixture of
useful programs and - in the best academic tradition - indulgently
useless ones! REC holds contests about once a year. Submissions are
welcome to all areas.

REC is edited and published by Dr. Mike Ecker, a Penn State math
professor. Some of you may remember Mike doing this sort of thing in the
mid-1980s in Popular Computing, Creative Computing, and BYTE (e.g., he
founded "Mathematical Recreations" in Byte in 1984 and wrote the
"Recreational Computing" columns in the other mags).

The level is lower-college, but high-school students can and do read and
enjoy it.

REC is a newsletter/magazine with programs, including optional disk of
same supplemental to the magazine. (The option, called REC-on-Disk, is
separate from and different than REC itself. REC-on-Disk contains all
the programs plus bonuses, shareware, etc.) Though most programs are for
PCs, there are often translations for Macs.

There is no index of back issues, as almost every issue is a mixed bag,
but all back issues are available. Mike will also send more info by
snail-mail or correspond directly.

To subscribe: Send $27 payable to Dr. M. Ecker or to REC (address below).
This covers one year. To cover higher postage outside USA, it's $29 to
Canada, $33 other Americas, $36 elsewhere.

REC is a mathemagical publication for thinking readers. Since Jan. 1986
it has been devoted to the interplay of computers, mathematics, &
recreation (as well as reviews, humor, trends, puzzles, programs, &
more). $27 annually in USA, higher elsewhere. Please inquire about
sample issues.

A. K. Dewdney's _Algorithm_ went under (unfortunately).  It is listed in
reference/magazines.  I got a letter from them July 6 stating that
publication would cease for an indefinite period of time :(

Mathematical Digest
-------------------

This *cheap* quarterly periodical is produced by John Webb of the
University of Cape Town (UCT) Department of Mathematics and is aimed
primarily at about Grade 8 to Olympiad level.

There is a local bias towards South African high school math affairs,
naturally, but world math news is also covered (latest largest primes,
proof of Fermat's last theorem, preparation for IMOs in Hong Kong and
Canada...).  It is also a great source of *problems*, *puzzles* and lots
of material for teachers and recreational mathematicians.

The latest, typical, issue includes:
Article on Fermat's Little Theorem
Article on Industrial Mathematics (sort of career guidance)
Article on differing date-writing conventions
"Limarithmeticks" (A graduate student at Trinity...")
Results of UCT Mathematics Competition (not astoundingly interesting if
you're not from the Cape Town area but the questions in the papers get
published too)
Article on "A First Look at Congruences"
Grade 10 & 11 question papers of Canadian Invitational Mathematical
Challenge

*Regular features:*
_Talent Search:_ The original objective is to find talent for upcoming
South African IMO teams, but everyone can join in.  Write in (or have
the correct copy of Mathematical Digest) and get back Olympiad problems.
"Earn" the next sheet by sending in answers.
_Sharp Calculator Competition:_ (only Southern African school pupils
eligible to win, as far as I know, but the problems are nice, e.g.
1. Prove that if a and b are positive real numbers such that a^3 = a + 1
and b^6 = b + 3a, then a > b
2. Three corner squares of a 12 x 12 chessboard are removed.  Can the
remainder be covered by 47 1 x 3 tiles?
_Problems_ from various competitions world-wide.
_Howlers_ Journalistic snafus, e.g. 350% price decrease.  Good for "spot
the problem" teaching.
_Page fillers_:  Quirkies, puzzles and problems

This magazine is *cheap*: I get mine mailed to me for R3 each (approx
US$1).  If you are overseas you'll have to pay a little extra for
postage.  The format is approx. 30 pages of A5 size (about half letter).

Back issues are available.  These are a treasure-trove of problems from
Grade 8 or so to Olympiad level, e.g. A farmer has a circular field of
radius R.  He tethers a goat to a stake driven into the circumference
and adjusts the length of the rope so that the goat's reach is
restricted to a radius of r.  What value of R/r is required if he wants
to limit the goat's access to half the area of the field?

Each issue has an order form for various related publications from the
University of Cape Town, such as past IMO and UCT Maths Competition
papers, "A Mathelete's Training Guide", 100 Olympiad Problems, UCT
Mathematical Afternoons lectures/competitions/problems and booklets on
various topics (e.g. Vector Algebra, Complex Numbers) for high school
pupils who want to reach towards university maths.

I have no connection with UCT, its Math Dept or Math Digest.

Why isn't "Eureka" listed in the FAQ?  It's a journal which usually
contains some puzzles.  Contact address; Eureka Editor, Arts School,
