IN MEMORIAM, MARGARET SINCLAIR
http://research.news.yorku.ca/2012/02/28/passings-margaret-sinclair-taught-mathematics-to-future-teachers/
It is with great sadness that the Forum has learned of the
death of Margaret Sinclair.
Co-director of the York/Seneca Institute for Math, Science &
Technology Education, and a professor in York University's
Faculty of Education, Margaret participated in several of the
Forum's earliest residential institutes while earning her Ph.D.
in math education. At our third Advanced Summer Institute,
fourteen years ago, Margaret developed a unit entitled "Algebraic
Problem Solving Using Spreadsheets," the principles of which
remain relevant today:
http://mathforum.org/workshops/sum98/participants/sinclair/problem/intro.html
Despite the distance between southeastern Pennsylvania and her
hometown of Toronto, Margaret quickly became part of the
Forum's extended family. Over one particularly memorable
weekend, Forum Problem of the Week Administrator Annie Fetter
and Margaret had the pleasure of going to the then-newly opened
SkyDome (now known as the Rogers Centre) -- the first time
Margaret had ever attended a professional basketball game. The
next night, they took to the ice to enjoy that most Canadian of
pastimes after Annie's casual inquiry, "Do you guys ever go
curling?" elicited looks of astonishment among Margaret's
family of six, who answered, "We LOVE curling! Would you really
want to go?!"
Margaret leaves her husband of 43 years and nine children
and grandchildren.

YOUTH NORTH AMERICAN BRIDGE CHAMPIONSHIPS
http://www.bridgeiscool.com/events/youthnabc/
The American Contract Bridge League (ACBL) celebrates its 75th
anniversary this year -- and holds its annual Youth North
American Bridge Championships (NABC) in Philadelphia Thursday,
19 July - Saturday, 21 July.
Any player 19 years of age or younger with fewer than 5000
ACBL masterpoints may participate -- and compete for the $1,000
and $4,000 scholarships. Register by Friday, 15 June, in order
to receive a gift.
This year's Youth Championships include a live panel discussion
featuring former youth players who went on to current stardom,
such as Player of the Year Joel Wooldridge, Fred Gitelman,
Gavin Wolpert, Jenny Wolpert, and Adam Kaplan.
Part math, part science, part logic, part reason, bridge
embodies cooperation, logic and problem-solving. As a
partnership game, bridge also cultivates trust, communication,
and patience.
For lessons and other teaching materials, check out the ACBL's
freely downloadable teacher manuals:
- Bidding in the 21st Century
- Play of the Hand in the 21st Century
- Defense in the 21st Century
http://www.acbl.org/teachers/materials.html
A not-for-profit organization founded in 1937, ACBL today is
the largest bridge organization in the world, with more than
160,000 members living in the United States, Canada, Mexico
and Bermuda.

"Anything with a square inside a square root cries out for a
trig substitution."

"TRAVELLING SALESMAN" MOVIE PREMIERES
http://www.travellingsalesmanmovie.com/
Also coming to Philadelphia this summer, on a silver screen
just blocks from the Math Forum office: the premiere of a
movie about the most vexing open question in computer science.
In the intellectual thriller "Travelling Salesman," four
mathematician characters weigh the ethical implications of
their scientific breakthrough -- a discovery that might also
lead to the destruction of the fabric of humanity. To learn
more about the mathematics of traveling salesman problems,
check out the Ask Dr. Math conversations
Traveling Salesman Problem: Is there an easy solution to the
"Traveling Salesman Problem"?
http://mathforum.org/library/drmath/view/52267.html
A Quick Overview of P vs. NP Problems: Can you explain what P
and NP problems are at a level that a high school student
can understand?
http://mathforum.org/library/drmath/view/71720.html
The team behind "Travelling Salesman" has credits that range
from the London Film School to the Cannes International Film
Festival to Philadelphia's own Temple University. Admission to
the debut, Saturday, 16 June, is free on a first-come,
first-served basis; it then screens at the New York City
International Film Festival, in August.
To lend support for a wider distribution deal, writer/director
Timothy Lanzone asks moviegoers to follow "Travelling Salesman"
