Hi,
This is the link to our demographic/attitude survey for 2013-2014. We’ll take a few minutes to fill it out at our first meeting of the year, Monday October 21, at 6:00 pm. Hope to see you there!

Next Meeting March 2! Also, recap of meeting Feb 23
Hi everyone,
Our next meeting is TOMORROW, Saturday March 2 at 9 am. We will hear about “hypercomplex numbers”. If you like complex numbers, you’ll love hypercomplex numbers!
Last time, we had a very good session led by Dr. Hui Ma, on counting with different number bases. See her slides and problem set below. Share your solutions and questions here, or bring them to tomorrow’s session. See you there!
Recap of Meeting Monday Feb 4
Hi everyone,
Last time (at our Monday evening meeting), we talked about graph coloring problems. This idea has applications to coloring maps, scheduling problems, and lots of other things.
Dr. Swenson’s presentation and problem set appear below. Note: there are many unsolved problems in this area. If you go to the last page of the presentation, there is a link to a list of unsolved problems that people are interested in.
Our next meeting is Saturday, Feb 23, at 9:00 am (the regular time). See you then!
Recap of January 26 Meeting
Hi everyone,
We had a good meeting last time. Dr. Nag described some ideas from probability, and then we worked on some problems. We saw quite a number of different applications, from playing poker to comparing birthdays to matching socks!
The last couple of problems were a little tricky, I think, so post any ideas in the comments, and bring your ideas to the next meeting. (NOTE: THE NEXT MEETING IS MONDAY NIGHT, FEB 4, from 6:00 to 7:30 pm!)
Dr. Nag’s problem set is below (.pdf format). See you!
Saturday Jan 12 meeting CANCELED!
Hi,
We canceled our January 12 meeting due to weather. 😦
Hope to see all of you on Saturday January 26. Thanks!
Next meeting Saturday 12/8 (also, problem set from last time)
Hi everyone,
Hope to see you again this Saturday, when Dr. Stone will be leading a session on careers in mathematics. Due to technical difficulties in our usual room, we will plan to meet in Jonas 202 instead (where we ended up last time).
Also, I’m attaching our problem set from last time (on the Pigeonhole Principle). Take a look, and feel free to attach any comments here on the blog!
Next meeting Saturday 12/1
Hi,
Just wanted to remind you all that our next meeting is this Saturday, Dec 1 (9:00). We are pleased to welcome Ms. Kristel Ehrhardt, who will be talking to us about the Pigeonhole Principle. See you there!
Recap: 11/17 meeting
Here is a list of problems from Dr. Nag’s talk this past Saturday:
I recommend starting with problems 4 and 5: the first couple of problems turned out to be tricky! Also, here is a link to some information to get you started:

The idea is to prove an infinite number of statements in order, by proving the first one first, and then showing that if one statement is true, then the next statement is also true. Enjoy!
Next meeting 11/17
Hi everyone,
Looking forward to seeing you all this Saturday, November 17, from 9:00-10:30 am. We’ll start by reviewing the voting systems stuff–please see/reply to the post below! Then we’ll start a new topic. See you there!
Recap of meeting 11/03
Hi everyone!
At our last meeting we discussed some different voting systems. You can find the slides from Dr. Swenson’s talk here: Voting Systems
We then worked on some problems related to that topic. You can find those problems here: Problem set
We’ll discuss some of these problems at our next meeting, so see if you can come up with any solutions. Or if you even have part of a solution, or an idea, post it here on the blog and see if anyone else can help out.
See you this Saturday, 11/17, for our next meeting!
