Gearing back up for the Putnam!

The William Lowell Putnam Mathematical Competition is a prestigious mathematics contest for undergraduates studying in the U.S. and Canada which has taken place annually since 1927.

Bucknell students have had some terrific performances in recent years. Last year, Bucknell ranked 68 out of 487 schools, and third in the Mathematical Association of America section that covers Eastern Pennsylvania and Delaware (EPaDel) behind Penn and Haverford. Skyler Le (’27, Mathematics major) had a score of 32, with a rank of 369 out of 4329 participants.

In preparation for this year’s event, taking place on Saturday, December 5th, there are also student-led practice sessions every Tuesday in the Olin Math Lounge, led by Meshkat Alam (’28, Physics and Mathematics major).

Want to try a problem of your own? Here’s an example to think about.

A grasshopper starts at the origin in the coordinate plane and makes a sequence of hops. Each hop has length 5, and after each hop the grasshopper is at a point whose coordinates are both integers; thus, there are 12 possible locations for the grasshopper after the first hop. What is the smallest number of hops needed for the grasshopper to reach the point (2021, 2021)?

Our department has a strong record of past performance. Shout out to past Mathematics and Statistics Department Competitions Committee chairs for keeping track of the history.

Last year (academic year 2025-2026) we had 12 participants. The Putnam for the academic year 2024-2025 was notoriously difficult. The median score was 2, with the average score at 8 (out of 120). We had 5 students participate. Skyler Le still went on to earn a score of 22 and was ranked among the top 500 participants out of approximately 4,000. In the academic year 2023-2024 we had 8 students participate. Skyler (42 pts) and Anh Tran ’24 (41 pts) were both ranked between 101 and 200 out of the 3,857 total students who took the exam. Bucknell’s team placed 3rd in the EPaDel MAA section. All of the students scored points, and 6 of the 8 students had scores in the double digits.

Students who like challenging math problems are encouraged to participate. No advanced mathematical knowledge is required; creative problem-solving is the goal. Participation is free and on-campus. Students who are interested should contact Prof. Langford for more details!

Are you an alum who participated in the Putnam? We’d love to hear about what that experience was like for you, so reach out on LinkedIn! Want a chance to be featured in a future blog post? Respond to our question of the week here, and your answer may be chosen for a future post.

Chalkboard Discussions

This semester, students, faculty, and staff have contributed to weekly chalkboard discussions that have taken a variety of forms.

We started off with a controversial one. Are there more wheels or doors on Bucknell’s campus? What counts as a door? A wheel? That’s all part of the fun!

Then we practiced our log scales by guess-timating the collective weekly screen time for Bucknell students.

What is the collective weekly screen time (in minutes) for Bucknell students? Votes cluster in the 10^4 and 10^6 ranges on the log scale.

By week 3 we were all already thinking about Fall Break and dreaming about our perfect vacation spots. The Hot/Nature quadrant is most popular!

Points plot ideal vacation spots with the x-axis ranging from cold to hot and the y-axis ranging from nature to city. The nature/hot quadrant has the most points.

We broke out the special colored chalk to determine what color best represents math or stats while also creating a tessellation. Print and fold your own tessellation zine!

A tessellation of color tiles that best represent math or stats. Blues and pink/orange dominate.

Some good meta-discussion appeared when we were counting the number of different places we have each lived.

Dot plot representing the number of different places you have lived. The 2-4 range has many points, with 8 having another 5 votes.

We put our spatial reasoning to the test by trying to map our favorite spots on campus. Again, we felt this one deserved the special colored chalk. Print and fold your own four color theorem zine.

Ahead of Fall Break we considered what makes an ideal job environment in terms of how much variation there is in the day-to-day work and how much time we spend alone v. with other people. We have people with preferences all across the two spectrums. And yes, the colored chalk helps really paint the picture. 😀

Two horizontal axes with one going from every day the same to every day different and the other going from always alone to always with people. Colored lines plot people's preferences for their job environment across 2 scales. The lines span most of the spectrum.

Stay tuned for more chalkboard discussions after a much needed Fall Break!

Want S’more Mathematics *and* Economics?

The Mathematical Economics (MECO) major lets students interested in both mathematics and economics have the best of both worlds. They get to pick a track (theoretical, computational, or statistical) to tailor their courses toward their interests.

MECO majors across multiple class years joined faculty members in Mathematics and Statistics and Economics to roast some marshmallows, make some s’mores, and form connections across class years.
