||Math Club invites you and your friends to "A
Brilliant Young Mind" at the Knickerbocker Theater (downtown
Holland) on Friday, December 4. We plan to meet in the lobby at
approximately 7:20 pm Friday and then find seats. Bring your Hope
student ID for free admission. The movie has both math and romance, so
it must be good!
Movie description (from the Knickerbocker website):
In a world difficult to comprehend, Nathan struggles to connect with those around him - most of all his loving mother - but finds comfort in numbers. When Nathan is taken under the wing of unconventional and anarchic teacher, Mr. Humphreys, the pair forge an unusual friendship and Nathan's talents win him a place on the UK team at the International Mathematics Olympiad. From suburban England to bustling Taipei and back again, Nathan builds complex relationships as he is confronted by the irrational nature of love.

Hope again had a great turnout of students participating in the Michigan Autumn Take-Home Challenge on November 7 this year.
Students competed with other students around the state (as well as other states) working in groups on ten interesting problems. We look forward to hearing the results in the near future.
The following students competed (grouped by team):
|Math in the News: Sports outcomes are quite predictable|
few weeks ago Michigan State's football team beat Indiana in what
could be described as a close game with a final score of 52 to 26. How
is a 52-26 game close? While most of the game was very close, MSU
scored 21 points in the last five minutes while Indiana mostly stood
there and watched.
Apparently this is not an unusual event in sports. Researchers at the University of Colorado and the Santa Fe Institute recently published a paper on the scoring patterns that occur in different sports with most of their research done by looking at basketball games. They found that the highest leads tend to occur fairly early or fairly late in games. While scoring in these times tend to be more erratic, most of the game is similar to watching ten players flip coins. Speaking more mathematically, they found that scoring during the most of the game conforms to a "random walk process."
