|This week's colloquium
will explore the world of chaos
|Title: Does God work through Chaos?
NEW MATHEMATICS REVEALS THE
INNER WORKINGS OF NATURE
|Speaker: Prof. Timothy Pennings,
|Time: Tuesday, September 21 at 4:00 p.m.
do the continental divide, the flap of a butterfly's wings, and a straw
on camel'sback have in common? Why are tree branches, mountain
ranges, and your circulatory system self-similar? How can simple
mathematical formulas command computers to generate incredibly complex
and intricate pictures?
Exploring the world of chaos and fractals, we will see how dynamical
systems bring about natural forms and processes, and may provide a way
for God to invisibly guide the universe. (If you already have the
universe figured out, don't bother coming to this colloquium!)

|Tuesday is the
new mathematics colloquium day
In "The Sniffing Accountant" episode of Seinfled, the following
dialogue occurs between Kramer and Newman. What's today? It's Thursday. Really? Feels like Tuesday. Tuesday has no feel. Monday has a feel,
Friday has a feel, Sunday has a feel.... I feel Tuesday and Wednesday...
We will be trying to make Tuesdays
feel like colloquium day this semester by having the majority of this semester's
colloquia on Tuesday instead of our traditional Thursday. The following
is a tentative schedule of this semester's mathematics colloquia.

A great time was had by all
during the Smoothies and Fun event held earlier this semester. Students,
faculty and some faculty kids enjoyed each other's company, some delicious
smoothies, sidewalk chalk, and unicycle rides. Elvis along with a small
swarm of bees also came out to the event. Below we can see the faculty
hard at work, students tasting the product, and Maya (Prof. Edward's daughter),
working on a drawing.
Undergraduate Mathematics Conference is soon
The Department of Mathematics
at Grand Valley host the thirteenth annual Michigan Undergraduate Mathematics
Conference (MUMC) on Saturday, October 9, 2010. Hope College will
be taking a group of students and faculty. They will leave early in
the day and return in the evening.
Undergraduate students will be giving 20-minute
oral presentations on many areas of mathematics, statistics or related
disciplines. Such areas include undergraduate research projects, interesting
class projects, history of mathematics, or expository talks on interesting
mathematics. Students are also encourage just to attend as there
will be presentations on careers in mathematics, information about mathematics
graduate programs and REU programs.
Students interested presenting
need to register by September 27 and those interested in just attending
need register by October 1. (Both of these sign-ups need to be done
online.) Students wanting to ride with the group to MUMC should
sign up with Prof. Tim Pennings by Friday, October 1 (he has a sign-up sheet outside his office
door, VWF 213). For more information
about the conference and to sign
up to attend, visit the MUMC web page at http://www.mumc2010.org.
pitcher uses mathematics and statistics along with his fastball
a newspaper article from this past summer Detroit Tigers pitcher Max Scherzer
talked about using advanced metrics to evaluate his results during the
course of the season. Scherzer studied business finance at the University
of Missouri and scored a 35 out of a possible 36 in math on the ACT. He
tracks his pitches and analyzes the results using advanced metrics.
Scherzer said. "You just have to let go of those and focus on the next
batter, the next game. You can't do anything about bloop hits. "And this
game still comes down to pitch execution, scouting reports and mechanics.
But advanced metrics helped me see things I had not seen before." For

of the Fortnight
In our previous problem of the fortnight, we looked at the following
question: The pages of a book are consecutively number from 1 through
384. How many times does the digit 8 appear in this numbering?
There were about as many solvers of our last problem of the fortnight as
pages in our book. Even though the entire problem of the fortnight
staff has been busily grading and recording these, they did not get them
done in time for the current newsletter. The names of the correct problem
solvers will appear in our next newsletter.
A digital clock shows 2:35. This is the first time after midnight
when all three digits are different prime numbers. What is the last
time before noon when all three digits on the clock are different prime numbers?
Write your solution
(not just an answer) on a piece of prime rib or your favorite prime
minister and drop it off in the Official Problem of the Fortnight
Slot outside VWF 212 by 3:00 pm on Wednesday, September 29.
As always, be sure to include your name, the name(s) of your professor(s),
and your math class(es) -- e.g. Pry M. Number, Dr. Com Posite, Math
235 -- on your solution.
