The 2017 Michigan
Autumn Take Home Challenge (or MATH Challenge) will
take place on the morning of Saturday, November 4
this year. Teams of two or three students take a

found in the undergraduate mathematics curriculum. Each team
takes the exam at their home campus under the supervision of a faculty
|Mathematicians discover that two types of infinities have the same size|
was in interesting article in Quanta Magazine recently
about infinity. The
Measure Infinities and Find They're Equal discusses this recent
discovery that two types of infinity that were long thought to be
different sizes, do, in fact, have the same size. The article gives
some history about infinities and how they can be compared.
Career Opportunity Day
Auto-Owners invites you to their annual Information Technology & Actuarial Career Opportunity Day! The event is on Friday, October 20, 2017 from 10:30 a.m. to 4:00 p.m. IT/Actuarial Day shows students how their degree can be used in the insurance industry.
Sophomores, juniors, seniors, and recent graduates with majors in Mathematics and Computer Science are invited. Faculty is also welcome! Each faculty member who wishes to attend should fill out a registration to ensure we adequately prepare for the correct number of attendees.
More information and registration should be available soon and will hopefully be in the next newsletter.
Solvers of the Fortnight
|In our last problem of the
Fortnight, we gave the figure shown where the
blue triangle POQ is isosceles since sides OP
and OQ both have length 4, theta is the angle POQ at the bottom of the
triangle, and a pink semicircle sits atop the isosceles triangle.
Congratulations to all those that gave correct solutions: Jacob Conroy, Matthew Dickerson, Calvin Gentry, Keri Haddrill, Karthik, Karyamapudi, Philip LaPorte, Kenneth Munyuza, Andrew Nguyen, Sarah O'Mora, Alex Osterbaan, Zheng Qu, Forest Rulison, Hugh Thiel, Jincheng Yang, and Yizhe Zhang
of the Fortnight
I've come out second best in my battle with the union," said Noah van
"How so?" asked his sister Joan.
"Well, I needed to have the union workers move thousands of crates. The exact number," said Noah, consulting his notebook, "was 69,489. The job took nine working days. I didn't think the union workers were putting all they had into it, but the union leaders thought otherwise. Every day after the first day, I put six more workers on the job; and every day after the first day, each of the workers -- by arrangement -- shifted five fewer crates than was the quota for the day before. The result was that, during the latter part of the period, the number of crates being moved actually began to go down."
What was the largest number of crates moved on any one day?
Tape your solution -- not just the answer -- to a crate of clementines, and drop it by the Problem of the Fortnight slot outside Professor Pearson's office (VWF 212) by 3:00 p.m. on Wednesday, October 18. As always, please be sure to include your name as well as the name(s) of your math professor(s) -- e.g. Woody Kreight, Professor DeKreese -- on your solution.
