All Girls/All Math 2014

This week, I’m teaching one of the parallel “Codes and Cryptography” classes at the All Girls/All Math camp at University of Nebraska-Lincoln. It’s so much fun to be in a room full of budding mathematicians from all over the country, and it reminds me of what it felt like to love the idea of math before getting too deep into any particular specialization.

I’ve made a few resources for the class, which I’ll drop in this post as the week continues.

Obviously, the rock climbing links come first…:
Bouldering vs. Top-Roping (vs. Lead-Climbing)
Rock climbing and teaching math

And here are some relevant math links:

The Bletchley Circle on PBS:

A quick review of the symmetric cryptography systems we talked about on Day 1:

Here’s an article about a new kind of space race — the race to bounce perfectly secret codes off low-orbit satellites using quantum cryptography:

For encrypting and decrypting messages, you can play with the web apps at http://www.cryptoclub.org.

And after the jump, there’s an except lifted from a blog post by Cathy O’Neil at mathbabe.org:


The end of the first semester is almost here…

You know, in my first semester of graduate school, I celebrated the end of every week. “I made it one more week!” was the refrain for all the new grad students.

My first semester as faculty? By the end of every week I was too tired to even form a coherent sentence. Maybe it’s because there isn’t exactly a whole class of newbie professors who see each other everyday, or maybe it’s because there’s always a full weekend’s worth of work to do, but I just didn’t work up the energy for celebrating on Fridays. But now that the end of the semester is almost here, I am starting to feel like it’s time to congratulate myself for making it through without any seriously huge screw-ups. (For those keeping score at home, there were at least 4 moderate screw-ups.)

One of the things that’s surprised me the most about this semester is that I have a pretty good idea of who my students are as people. In grad school, my students didn’t come to office hours, and they didn’t make a special effort to get to know me or let me get to know them. It’s the opposite story here. I see my students a lot. They participate in class. They’re funny and clever and quirky and curious and invested. The biggest surprise, to me, is that I have the emotional wherewithal to really care about 60 students. This was not something I was expecting to learn about myself! I was expecting to learn things like, “I’m not good at coming up with examples on the fly,” or, “I can draw a pretty convincing circle.”

The last week will be sad. Although some of my Calc 1 students will take Calc 2 with me, I won’t see my Linear Algebra students next semester. There are some who might never take another class with me! I’ll miss these people that I’ve come to know.

One month gone

I had this grand plan that I would begin my days by leisurely blogging. Ha.

The semester is flying by! I am barely on top of the things I absolutely need to do everyday, and even then, I occasionally find myself with half a lecture prepared and twenty minutes to finish the other half. Fortunately, I work well under pressure. Unfortunately, I don’t do anything else well under pressure.

My job here is intense; the students are smart, motivated, committed, and genuinely kind and thoughtful. I’m used to having to exert great force to get students to come to office hours, visit a tutor, or take advantage of opportunities to help them learn. Here, many students don’t even need my intervention. Those that I have nudged to seek a little help have been willing and thorough. I really, really love this atmosphere!

The most difficult part of the job right now is figuring out how long things will take and then scheduling enough time. This weekend, for example, I would like to get my portion of midterm grading done. I also have a stack of writing assignments from my writing intensive linear algebra class to finish grading (we teach proof writing alongside linear algebra).

Next weekend, I’m going to the AMS sectional meeting in Louisville; I have to write that talk, and I should probably get my lectures for the beginning of the week prepared, too.

I’ve been managing to do some fun stuff, too. There’s a pub trivia night on Tuesdays here at the Little Pub on campus. I’ve joined a faculty team (“No Extra Credit”) and we’re doing pretty well. I go to the climbing wall a few times a week, which is really good for my mental health. Tonight I’m going to a jazz performance, and tomorrow there’s a “Fallcoming” picnic for the math department where majors, faculty, and alumni get together.

Today a student asked me to mentor his senior project.

I’m slowly starting to feel like I fit in here.

It was awful, but I’m pretty sure this is a dream.

I had my first pre-semester stress dream. I was teaching my first day of calc 1, and I had this really cool activity planned that would get students out of their seats and talking to one another, but it totally flopped. Not only that, but I couldn’t get the document projector to display the syllabus (which I had to borrow from a prepared student because I didn’t even have a copy of the syllabus), I barely managed to get the students to pay attention, and I forgot to assign the first homework assignment.

I went back to my office, and someone came by and asked how my first day went.

“Well, it was awful. But that’s okay. I’m pretty sure this is a dream. I’m supposed to teach Linear Algebra in an hour and I don’t even have the book. Also, this isn’t my office.” (It wasn’t. My dream office was in a hard-to-find turret attached to the math building. I shared this office with several of my coauthors and former office mates and a person-sized bat.)

There’s something to be said for being a mathematician, even while sleeping. I deduced the heck out of that one. Usually there a few little snags in the dream-logic that clue me in, even in sleep mode. (Take that, smart phone. There’s something you can’t do!)

Do you have stress dreams, and are you able to rationalize your way to the understanding that you’re in a dream?
