Lights Out Colloquium 
Title: Lights
Out: Some Puzzles, Some Results, and Some Questions 

Speaker: Darin Stephenson, PhD, Hope College Math Department  
Time: Tuesday, January 26 at 4:004:50 pm  
Place: VanderWerf 102 
Upcoming Colloquia 

The following colloquia are currently on the
schedule
for this semester. Others will be added as the semester goes along.

Math Club News 

The Math Club invites you and your friends to The
Theory of Everything on
Friday, February 5 at 9:00 pm in Winants Auditorium in Graves
Hall.
The movie features the life of Stephen Hawking, one of the world's
foremost physicists. The movie tells the heartfelt story of
Stephen
falling in love with arts student Jane Wilde and raising a family, all
while his body is failing him and his popularity soars as his brilliant
ideas become widely known. For more info on the Hope Math Club's latest and greatest activities, visit their FaceBook page (and request to join the group). 
Kaggle Data Science Bowl 

The goal of the Second
Annual Kaggle Data Science Bowl is to transform how we diagnose
heart disease by developing mathematical algorithms that automatically
calculate heart volume from MRI scans (using about 27 Gb of MRI scan
data!). The data we are analyzing looks like this.
The next team meeting will be Saturday, January 23 at 3 pm in VanZoeren
276 (bring a computer). If you are interested in joining the team
and have taken multivariable mathematics 1 or have Python programming
experience, please contact Paul Pearson (pearsonp@hope.edu). 
Math in the News: Building a better snowman 
Next
time you go out to build a snowman, you might want to consult with Dr.
James Hind of Nottingham Trent University since he has developed a
formula to help you develop a better snowman. He says the snowman
should be 64 inches tall with snowballs of 31, 20, and 12 inches in
diameter. (I guess compression takes care of the missing inch.) His formula, shown on the left is also designed to give scores for the purity of the snow, facial features, and accessories besides size and proportion. He also suggests making the snowman out of snow that is 32 degrees Fahrenheit or less. (I think otherwise it would be a puddle man!) Click here to read more about how to make the ultimate snowman. 

Math Road Trip 
Here
are two opportunities this semester for Mathematics and Mathematics
Education majors to attend conferences in Michigan. On Saturday,
February 27 the Math in Action at Grand
Valley State
University presents lively and informative discussions of current
issues in mathematics education while providing an opportunity for
practicing PreK – 12 teachers,
prospective teachers, curriculum directors, and college and university
faculty to share ideas, concerns,
and resources. The conference consists of six hourlong sessions with
eight separate interactive
presentations during each. On Saturday, March 19 the MI‐AMTE Conversations Among Colleagues will be held at Western Michigan University. This conference was designed to facilitate conversations between and among mathematicians, mathematics educators and leaders in mathematics education related to mathematics education and the preparation and continuing professional development of teachers of mathematics PreK‐College. For Hope College Mathematics and Math Education Majors, student registration fees and transportation via a Hope College Van will be covered by the Math Department. Both trips are being organized by Dr. Mann. Drop him an email at mann@hope.edu or stop by his office, VanderWerf 213, to find out more or reserve your seat in the van. Contact Dr. Mann by the following date(s) to participate with department funding: Conversation Among Colleagues by Thursday, January 28, Math in Action by Thursday, February 11.
