**Math-Frolic Interview #12**

"

*If you already love math, welcome. If you were traumatized by a math class years ago, welcome. If your relationship with math is complicated, welcome. I hope there will be something here for everyone.*"

-- Evelyn Lamb, from her first blog post for "Roots of Unity"

Evelyn Lamb is a mathematics writer and post-doc who was a relatively recent addition to the stable of bloggers at

**Scientific American**. Her blog "Roots of Unity" is fittingly subheaded, "

*Mathematics: learning it, doing it, celebrating it"*and her SA profile is here.

If you're not familiar with her, you'll soon feel much more familiar after reading the wonderful, extensive answers she gave to questions I posed for her (and as usual, I've highlighted, in bold, parts of the responses). Enjoy:

************************************

**1) You mention in your blog bio that you didn't really get interested in math until your junior year of college… that is so contrary to what I usually hear from mathematicians (who often grow up with an unusual and inherent interest in math and numbers from early on). Can you describe a little further what that was like coming to math relatively late in your academic life (did it feel odd? did other math majors look a bit askance at you? was it a smooth or difficult transition?…)?**

**As a child, there were times that I learned about mathematical concepts that I found really fun and interesting, but I didn't realize they were real mathematics.**My dad taught me about bases when I was in elementary school. I learned to count in binary on my fingers, and I loved figuring out how to represent numbers in different bases and the fact that decimal notation is a choice, not something intrinsic to numbers. But I didn't connect this concept to math.

**Math was where you learned the routine process of multiplying, not the fun process of representing your age in base eight. (And figuring out that no matter what your age, if you represented your age in base (your age), the answer was 10. Whoa!**)

**In general, I grew up thinking of math as just formulas: you look at a problem, there's one way to do it, you do it, and then you get the one and only answer.**

**I was good at this, but it didn't excite me.**I went to the Texas Academy of Math and Science for my last two years of high school. That is a program at the University of North Texas where high school students who are good at math and science take UNT classes during their last two years of high school. There, I went through the calculus sequence to multivariable calculus, so when I got to college, it made sense to me to work on a minor in math because I had so many math credits already going in. My junior year, I took a class that really changed the way I looked at math.

**Coming to math so late in the game has been a challenge, and I still sometimes feel "behind."**I was one of the top math students at my university, but at the time their math program was not what it is now. My first semester of grad school, I got a big dose of reality when I saw how difficult the qualifying exams were and how much better prepared everyone else seemed to be. My grad program was very small, and faculty and other grad students were very supportive of me. I felt out of my league a lot of the time, but it was internal. No one there tried to push me out or make me feel like I didn't belong.

**2) You also mention that an "inquiry-based learning" class is what really turned you on to the beauty/creativity of math. Again, can you say a little more about what were some of the problems/examples that most moved you?**

**The class, basically "intro to proofs," was taught using the Moore method, or inquiry-based learning, meaning that our professor prepared sheets of definitions, examples, and theorems for us to work on outside of class.**During class periods, students would present material for the whole class, and those who weren't presenting would ask questions or point out errors in the proofs. The professor worked very hard to make it a "safe space" for people so they wouldn't feel bad about being wrong. We pointed out errors in each other's work, but it was always done in a constructive, kind manner.

**That class, more than anything else, showed me that math is a creative discipline.**

**There were two mathematical concepts that stuck with me the most from this class. The first was proof by induction. Not only did we use this technique, but we also came up with a proof that the technique worked. That was the first time I had really thought about math as theorems and not formulas. I was used to learning a technique and trusting that it worked, not actually understanding why it worked.**(My professors had presented proofs of theorems in calculus, differential equations, linear algebra, and so on, but I had always thought of those theorems as times to "tune out" until we got to the part where we used them to solve a problem.)

**The second concept was proving that the rationals are countable and the real numbers aren't.**I had worked for about a week on a proof that the irrationals were of a different cardinality than the rationals—my intuition said that n^2 just had to be fundamentally "bigger" than n, and there was some kind of "limit" argument that the irrationals had to be more numerous than the rationals because of this.

**Obviously, my proofs were not correct, and when another student presented a (basically) correct proof, I was very resistant to it. It took a while for me to learn to accept it, but that process of wrestling with the idea for so long was formative for me as a mathematician.**

**I'm not saying that inquiry-based learning is necessarily the best way to teach all topics, or the best way to teach all students, but I can say that there is a 99% chance I would not be in math today if I hadn't taken that inquiry-based learning class.**

**3) How did the idea for your blog, "Roots of Unity," for Scientific American come about?**

I had a fellowship at

**Scientific American**during the summer of 2012, which is how I started writing about math and science. Through that, I met Bora Zivkovic, the blogs editor for

**Scientific American**. Both he and my immediate supervisor Robin Lloyd recognize that

**Scientific American's**audience would like to read more math stories, so they were very supportive of my coming on board with my own blog. I'm really grateful to both of them and my other colleagues at

**Scientific American**for encouraging me and helping me find an audience by giving me the

**Scientific American**platform.

**[Bora has a knack for finding and promoting blogging talent! and you certainly seem a great fit for SA.]**

**4) I would guess that anyone writing ongoing math pieces for Scientific American might feel the long shadow of Martin Gardner over their shoulder… is there some sense of that for you, or are your pieces different enough (and not restricted to recreational math) so that you don't feel that sort of connection?**

**I definitely feel the shadow of Martin Gardner! I do want to entertain people and help them engage with math, two things that he did very effectively.**I do not know very much about recreational math, so I haven't ventured into that world very much yet. And there are already so many places where that is done so well! I will never be Martin Gardner, but I try to see myself as an entertainer at least as much as an educator.

**For the most part, I want my pieces to make people happy. If they learn something as well, that's a nice bonus.**Sometimes I write about things that aren't happy, but I prefer the happy stuff.

**5) What are your favorite aspects of mathematics to study or read about? And what is your math post-doc work related to?**

**My field of study is hyperbolic geometry and Teichmüller theory, which is the study of spaces of hyperbolic surfaces. I use analytic techniques to attack geometric problems. I am a very visual person, and I love the visual aspect of hyperbolic geometry.**I love reading (or looking at) books of mathematical art, particularly when it has to do with hyperbolic geometry.

**I have recently gotten more interested in math history, which I am actually woefully ignorant of.**In my work for

**Scientific American**, I have come across some biographies of famous mathematicians and books of ancient Chinese math, for example, that fascinate me. I do love to read popular books about math, in part as professional "research": how do more experienced math writers approach the subject, and what are their personal styles?

**I am still working on finding my voice and tone, so hearing the masters do it is very useful to me.**

6) Who are some of your favorite mathematicians (living or deceased) to read?

6) Who are some of your favorite mathematicians (living or deceased) to read?

**I am an academic descendant of Bill Thurston, and his approach to geometry and mathematical thinking in general.**He has a famous essay in a 1994 copy of the Bulletin of the American Mathematical society called "On Proof and Progress in Mathematics," which is an interesting read about the way mathematicians should approach mathematics. It has been circulating in my corner of the math research community a lot since Thurston's death in August. (My corner of the research community is probably at least half mathematical descendants of Thurston.)

**I've also read two popular math books in the past few months that I really enjoyed: "Measurement" by Paul Lockhart and "The Joy of X" by Steven Strogatz.**They are very different from each other, but both are worth a read. I read

**Measurement**twice because I wrote two different book reviews of it, several months apart, and the second time through, I found it even more delightful. Lockhart reminds me of Thurston in some ways: both talk about math as a

*human*activity in ways that speak to me.

One of my uncles gave me Strogatz's book

**"Sync"**back when it was published, and I've tried to keep up with his writing since then. I was very excited that I got to meet him this past summer when I was in Ithaca for my brother's wedding. It turns out he was on my sister-in-law's oral exam committee. She is a grad student in physics at Cornell.

**-- I thoroughly enjoyed and reviewed the Lockhart and Strogatz volumes as well, and Bill Thurston was certainly one of the most loved and respected members of the math community.**

**7) In an earlier piece you wrote that working at Scientific American made you feel like "two different people" -- being a reporter of sorts (educating the public) for SA, but also still wanting to be a discoverer, as an academic mathematician… Now that you're a regular blogger for SA I imagine that writing for the public becomes increasingly smooth and enjoyable over time. How strongly do you still feel pulled in two directions, or are they more integrated by now?**

**I very much feel pulled in two or more directions, but that is pretty normal for me. I have always had many divergent (sometimes competing) interests, and I feel like I've spent most of my life fighting to keep as many options open as possible.**

**I am just the kind of person who wants to have lots of different mental stimuli over the course of a day or week.**I have the luxury this year of establishing myself as a writer/blogger before starting my postdoc. Once I get there, I will have a whole new challenge of balancing my new professional responsibilities with my desire to write about math for a broad audience, but I know a change of scenery will also give me new inspiration.

**My writing has given me a lot to think about when it comes to teaching, and I expect and hope that my work on my blog will help me become a more effective teacher.**

**8) How do you select the topics you post about on your blog?**

**My Valentine's Day post about continued fractions literally came to me in a dream, but that doesn't seem to be a consistent source of ideas.**I don't have a magic formula. I do get some ideas from press releases and arxiv papers, but I also just notice math in my daily life and in popular culture.

**When you dig far enough, everything in the world is made of math, so it's just a matter of choosing where to dig and how deep.**Right now I'm trying to formulate a blog post about why

**Project Runway**is my favorite math show on TV, for example, mostly because I want to be able to say I'm watching

**Project Runway**for professional reasons. (Nobody steal my idea, OK?)

**-- [just a guess, but I don't think you have to worry about that ;-) ]**

So far this year, I've been to three large conferences, and I've gotten lots of ideas from them. But I don't have one tried and true way of finding stories yet, which means

**a lot of the time I put into my writing is "invisible" and just consists in figuring out story ideas and rolling them around in my head until they work.**

**I am naturally attracted to stories that involve math and the arts because I find it easier to draw people into those stories and because I love the intersection**, so I like to have an excuse to spend a lot of time thinking about them.

**9) To round yourself out a bit, when you're not doing mathy things, what are some of your main interests/hobbies/activities?**

**I have way too many hobbies!**My mom is a musician, and I have been involved in music since I was a toddler. Currently, I play viola with some amateur chamber music groups and sing shape-note music, a kind of early American folk hymn singing. I also sew, which I actually think of as applied mathematics, and I have been trying to learn to crochet. My husband and I live about a mile from Lake Michigan, and when the weather is nice, we like to walk down to the lake and collect beach glass. We also collect it on trips if we're near a shore. We have a few vases and bowls filled with it, and I've used it for some art projects. We also like riding bikes, doing yoga, and playing ultimate frisbee, although we haven't done a whole lot of that recently. We both do a lot of cooking, and we love traveling. Recently, most of our traveling has been to math conferences and to visit family, but we try to work in some personal vacations as well.

**10) Any parting words, not covered above, you'd care to pass along to a math-oriented audience?**

**When you don't know what to do, do something. I think that's important both in mathematics and in life.**When I am teaching or tutoring, I find that students get stuck the worst when they are afraid to write anything down before they're absolutely sure they have the right answer.

**People sometimes think mathematics happens when a smart loner has a sudden bolt of inspiration, but**

**I think much more progress happens when people, often in collaboration, try lots of different approaches to the same problem until something works.**At all levels of study, much of mathematics consists of getting used to techniques that you can get an instinctive feel for what technique might work for a new problem.

**In life, I try to use the same approach. I don't know what I'm doing with my writing exactly, but I'm doing something, and I'm getting a feel for what works and what doesn't, and what kind of math stories people want to read.**
