Hope Student Receives Prestigious Mathematics Education Scholarship 


Hope students earn Outstanding Speaker Awards 

Four
Hope College Mathematics students won Outstanding Speaker
Awards at the Mathematical
Association of America’s annual national conference, MathFest, this
past
summer.
Sarah Hilsman (Real algebraic level curves), Anna Snyder (An extension
of a theorem of Polya), and Cole Watson (Graph pebbling and Graham’s
conjecture) all won prizes from Pi Mu Epsilon, the national mathematics
honorary society and Jiyi Jiang (Classify images using stochastic
neighbor embedding and mapper) won an award from the MAA.
All four of these students participated in research this summer under the direction of Stephanie Edwards, Chuck Cusack, and Paul Pearson. See below for some pictures of their excursion to Washington, DC for MathFest. 
Ice Cream and Fun 

Please
join the mathematics faculty and fellow math students for the Ice Cream
and Fun event on Friday, September 18 from 3:14 to 4:14 p.m. (that's pi
time to pi+1 time) We will set up in the Van Andel Plaza located
in
front of the Schaap Science Center. (We will use the Science Center
Atrium in case of rain). Come and enjoy delicious ice cream, some fun
games, and get to know your fellow math students and faculty.
Hope to see you there!

UN World Statistics Day Data Visualization Challenge 

As part of the celebration of World Statistics Day (WSD) on October 20 and following the release of the Millennium Development Goals (MDG) Report by the United Nations, the United Nations Statistics Division has announced the #WSD2015 Data Visualization Challenge competition. The challenge is to build an infographic or dynamic visualization featuring the latest data from the 2015 MDG report. Data and submission guidelines can be found on the WSD2015 Data Visualization Challenge website. If you are interested in working on this with a team of up to three people, please email Paul Pearson well in advance of the submission deadline (September 20). We may have more that one team from Hope College, so the more the merrier! 
Math in the News: Hinged Flat Torus 

A little more complicated than a Cheerio or a doughnut, Henry
Segerman, an Oklahoma State University mathematics professor, has
developed a hinged flat torus. (We had an article last year in Off on a
Tangent 13.6 about Segerman's Pumpkin Geometry.) Segerman created a
torus (the shape of a doughnut) that can be unfolded so that it results
in a flat shape. He's kind of messing with topology a bit here. You can see a video of the hinged flat torus and even purchase one for that special mathematician on your Christmas list here.
