At present, I write here infrequently. You can find my current, regular blogging over at The Deliberate Owl.

Me on the strip at a fencing competition.

Me, fencing in a competition at Vassar College in 2010.

Fencing: More than parries and ripostes.

I used a fence a lot. For ten years, I picked up a foil and went on guard on the strip two, three, sometimes five days a week. Or more, with tournaments on weekends. I was not alone: my teammates did the same. Yet despite the dedication so many of us gave to the sport, the first coach I had, George Platt, used to say that when it came to life versus fencing, "It's just fencing!"

However important the sport is, in the end, "it's just fencing!"

It's as important as you make it to you. The rest of your life, well, that matters too.

I was thinking about this recently in relation to other life decisions, balancing time and energy. And I realized: I really did learn a lot, being a fencer.

Priorities, commitment, and time management

I learned how to make something a priority. How to commit to something.

I was never late to practice, and only missed a day if I was coughing and running a fever. I gave up other clubs, movie nights, Halloween parties, and much more because I had practice, or I had to sleep, we were leaving at 4am for a competition tomorrow.

But remember, it's just fencing.

My coaches in college always stressed that academics came first. If you had a huge test that day, or if you had to a class that happen to clash with practice times, well, there was no help for it; academics came first.

But being busy was no excuse to skip practice. After all, we were all college students; we all had homework and tests and classes. By joining the fencing team, I was saying, this is a priority for me. I'm going to put time and energy into this. Joining the team meant that other things that could have been priorities -- other clubs, social events -- were not so high on my personal list. Fencing was. So I made time for it.

Sometime later, I was working on a academic project. My professor told me, "It's your project; if it matters to you, it can happen, it can be good. But it's your project. If you don't care about it, if you don't make it happen, well, it won't happen. And since it's your project, no one else will care."

Fencing was like that. If you didn't care how many bouts you won, if you didn't care how well you fenced, well, guess what, no one else would really care, either. Your teammates or your coach might be disappointed. But you're the one most invested in what you're doing.

Waiting by the strip for a bout to start

Waiting for a bout to start at the Denver North America Cup event in 2005.

Related to that: When I was fifteen or so, I was fencing in a local competition, a direct elimination bout against a woman of about the same skill level as me. We kept tying the score: 4-5, 10-9. The last round, I won. My dad said it was because I cared. It was partly endurance, too. But if you want to win, you'll put in more effort and go farther. You have to enjoy it. You have to be a good athlete. And you have to be competitive. I remember George saying once that if you don't care when you lose -- if you aren't upset that you lost -- then you didn't care about winning, either.

Failure, adaptation, and emotion regulation

When you fence, you make a lot of mistakes. You get hit, over and over, in the same way, by the same opponent, because you keep making the same mistake. It's frustrating. You lose a bout 0-5 because you kept making the same stupid mistake. Sometimes to a girl you used to beat 5-0. And the thing about fencing is that it's such an individual sport. If you lose, it's all on you. Sure, sometimes the referee makes bad calls. Sometimes the other girl just is a better fencer than you. But not always.

There are two parts to dealing with this. First, the practical side: You lost this touch. Or you lost this bout. What did you do and why didn't it work? Critically evaluate your actions. See the mistakes, or the places where someone out-fenced you. Try to improve. Adapt.

Me lunging on the strip, foil bent as I hit my opponent.

Me, fencing at a Bay Cup event in 2004.

George always taught that if what you're doing isn't working, do something else. Change something. Change anything. Sometimes, if you find yourself doing the same wrong thing over and over, it doesn't matter what else, so long as it's different: a different parry or attack, different timing or distance. Don't get stuck. Don't let your opponent score the same way twice. If what you're doing isn't working, change what you are doing.

The second part is emotional and mental. In a pool round in a tournament, you only have 5 or 6 bouts. You just lost one 0-5. You can't let that negatively affect the next bout. You have to move past it. Re-focus. You can't be flustered and upset when you step back on the strip.

I learned to consciously regulate my emotions and mental state, using combinations of music on my ipod, self-talk, and habits before and during competitions to reinforce states and moods that I empirically found to lead to me fencing better. You can't lose your cool. For me, I fenced best when balanced: Not too excited. Not too calm. Not too upset. Focused. Edged. Finding that state, keeping it, and regaining it was as critical to my performance as good hydration.

Practice and preparation

George also used to say that it was the practice you did six months ago that matters most in your competition today. And day of, I had my routines. You warm up before a competition. That isn't just to prepare your muscles - it was also part of getting ready mentally. Getting your mind in the right space. It was about eating well, and sleeping well -- not sacrificing an upcoming tournament to one evening off. If that meant missing parties, other events, whatever -- well, preparation was key. That was what commitment was. Sleeping was part of that. Eating, hydrating, training.

When taking a ballroom dance class two years ago, I realized I'd learned something else from all that practice: How to practice. You learn it slow, practice it perfectly, under control, slowly, until eventually, at top speed during a bout, you do okay. You can't practice sloppy and expect that when it matters you'll be any less sloppy. Practice perfect.

Lessons learned

My senior year at Vassar, there was controversy over whether varsity sports should count for academic credit. Suffice to say, one piece of the argument was that yes, you learn a lot doing a sport. If credits equate to learning, you learn as much -- if not more! -- in a sport as you do in other classes. You may learn different things. But you do learn.

(As a side note, the divisions between disciplines, quantifying or categorizing learning, and deciding what "counts" as an academic class don't always make sense to me.)

I learned to prioritize. To commit. To fail. To persevere. To adapt. To prepare.

I learned about the difference between achieving success and achieving excellence. I learned about confidence.

Ten years of competitive fencing. Wonderful coaches, great teammates, and a lot of things learned. Time well spent, I'd say.

Invitations

For my wedding, I designed my own invitations. Here's the art: line drawings of birch trees (one of Randy's favorite kinds of trees), a flowery vine wrapping around the edge, and a few butterflies (but look closely: one is actually a penguin!). I used black micron pens.

I took a photo of the page, opened it in GIMP, added all the invitation details with lovely text boxes in some fancy script, and printed them out on nice paper.

Thank you cards

The thank you cards I sent were similarly my own design—in this case, a line drawing of a magnolia flower, chosen because I had a nice reference photo of a magnolia flower on hand. These were printed on regular printer paper and folded up in fourths.

Cake toppers

While we considered being nerds and putting a Han Solo / Leia combo on top of the cake, we ultimately picked classy penguins. I made these with sculpey clay.

Centerpieces

The centerpieces for our reception were arguably the most elaborate part of my wedding crafts, simply due to the sheer number of moving parts!

Here's a reference photo of the setup for one of the tables.

five colorful sheets of scrapbook paper arranged in a circle on the floor, with several jars in the middle containing a candle and paper flowers, with scrapbook materials scattered around

Each table got five sheets of scrapbook paper, arranged in approximately a circle. In the middle, there were three jars. One held paper flowers; one held a candle; one held a wire tree covered in little monster finger puppets. All around that, we scattered materials for decorating the scrapbook pages: some pens, markers, crayons, and stickers. Somewhere in there was the table's placard—in this picture, Unity. That was our table. The other tables had names like Bliss, Felicity, etc.

The paper flowers were my solution to not having a florist. They went well with the crafty theme and my ribbon bouquet! The vases were reappropriated food jars that had interesting shapes—molasses, maple syrup, raspberry syrup, and so forth. I filled each with paper confetti strips and put three flowers in each.

Here are all the flowers:

The candles were fairly straightforward. I used modpodge to attach little pieces of semi-transparent paper onto reused peanut butter jars. I put a little 1x2in blue candle inside each one.

The last piece was the monsters. My older sister provided about a hundred felt finger puppet monsters she had made. I painted jars with turquoise, yellow, pink, and green glass paint. Then, I used green floral wire to make curly wire "trees" that sat inside. The monsters perched on top, one to a branch. I added a little sign saying "Adopt a monster!" so my guests would know they could take one home.

Dress

Picking a dress for a once-in-a-lifetime event is hard. I browsed dresses online. There were so many options. Did I want to wear something huge and white and over-the-top poofy? Something slim and sleek? I did want to wear a dress. I didn't mind the idea of it being white.

Fortunately, my mom still had her wedding dress. Fancy, white, and lacy, it was made in the '80s and had a train longer than I am tall. "You can have it if you want it," she told me. "That's why I saved it."

I liked the idea of wearing a family heirloom. There was something nice about that. Also the part where I didn't have to pick the style—the dress was already made and it was what it was.

"Okay!" I said. My mom mailed me the dress. I tried it on. The long, lacy sleeves were a bit much... especially for a June wedding in Boston. I didn't want to sweat through the sleeves. I had a tailor remove them.

The next step was to make the dress more "me." And that meant adding color!

The dress had a petticoat. Very poofy. I dyed it turquoise—fabric dye from the craft store and a plastic bin in my bathtub did the trick.

The dress also had a long, lacy veil, with lacy flowers all along the edges. I bought fabric dye in bright orange and magenta, and spent several afternoons carefully painting the flowers in alternating colors.

Much better.

Here's the full effect with the train and veil!

Shoes

The dress was just a little long (my mom is two inches taller than me). I didn't want to hem it, so I had to wear heels. Finding a good pair of comfy heels was tricky ... my feet are wide; most decent-looking heels don't fit. I wanted colorful shoes to go with my colorful theme. After browsing, a lot, I found these chunky wedges at some local store. The turquoise was a good base. I added thing ribbon bows along the back, and aded more ribbons and ribbon flowers over the toes. Perfect!

Ribbon-flower bouquet

I didn't eschew real flowers because I hate flowers. I like flowers. But I wanted to make my own bouquet. (And I didn't want to add "florist" to the list of other things I had to deal with before the wedding—I was busy enough trying to finish my master's thesis!)

I spent several weeks browsing other people's homemade bouquets online. Mine needed to be bright, colorful, and classy. I tried make a few different kinds of flowers—including with buttons, beads, and paper—before settling on ribbon roses as my favorite.

I ordered a bunch of satin ribbon online. A bunch. Bulk ribbon was cheaper. So much ribbon. Green, silver, purple, pink, purple, orange, turquoise, yellow with polka dots, shiny transparent pink, shiny transparent turquoise.... you get the picture. Most of it was 1.5-inch ribbon, which made a good size flower.

Then, settling down for many evenings watching random shows on Netflix, I made a bunch of ribbon flowers. I attached each flower to a green wire stem, made of floral wire, that I bought at Michael's. When I had a huge pile of flowers, I arranged the bouquet. Twisting the stems together held them in place, mostly.

I don't have great pictures of the work in progress, unfortunately! Here's all the flowers put together, after the bouquet was finished.

The next step was to hide the kind of ugly wire steps. I wrapped green ribbon around the stems and glued the ribbon in place with some tacky glue.

I cut turquoise felt into a flowery circle and used that to hide the rest of the stems.

I tied a couple long pieces of thin turquoise ribbon and more of the green ribbon around the base of the stems.

Voila! Here's the finished product.

Boutonnieres and corsages

For the rest of the wedding party, I made mini ribbon flowers for their boutonnieres and corsages. The flowers were made the same way as for my bouquet, but with 1-inch ribbon. Again, I used green ribbon to hide the stems.

New (old) project!

I've finally added a page about my summer at NASA Goddard Space Flight Center in 2011! I worked with over forty interns at Mike Comberiate's Engineering Boot Camp. The project I worked on was called LARGE: LIDAR-Assisted Robotic Group Exploration. Essentially, a small fleet of robots were designed to autonomously explore and map novel areas. Check it out!!

Finished year one!

I've recently finished my second semester of grad school at MIT! It was amazing. Updates soon -- my summer plans include revamping the website, adding more recent projects, and documenting some of the exciting things that have happened this year. We'll see how I do.

Concept: Glowing Orbs

Glorbs. Glowing orbs. Interactive balls that help you visualize and explore the dynamics of motion&mash;acceleration, velocity, rotation. Colored lights embedded in the balls give immediate visual feedback about how the balls are moving. Throw one up in the air, and watch the colors change from blue (high acceleration) to purple to red (little acceleration) and back to blue on impact as you catch it. Learn about physics!

The idea for glorbs evolved from a project I did in the Media Lab's Tangible Interfaces class the previous semester. My group came up with an idea for a wearable interface to motivate and guide collaborative, synchronous motion—i.e., pairs of wristbands containing LEDs that would change color and intensity as you move synchronously with other people wearing similar wristbands. We made a stop motion video showing off the concept, and a prototype wristband that lit up.

Why not make that class project come to life for The Other Festival? Randy, my husband, thought it'd be fun to do an electronics project, so away we went. Several brainstorming sessions later, the concept had evolved into something doable in the span of one semester—you know, not requiring a bunch of sensors and complex algorithms for measuring synchronous movement between humans...

Glorb Design

We prototyped on a breadboard. Wires, xbees, microcontrollers, LEDs... We used a triple-axis inertial measurement unit (IMU) to measure acceleration and rotation, which was streamed to an AVR microprocessor. There, it calculated average values and set the LED colors and brightness levels appropriately.

A wireless transmitter (xbee radios!) let us stream the data to a computer, so we could show a real-time graph.

Once we had settled on a design, Randy laid out a PCB. We ordered parts. We used the Media Lab's shop to machine the boards. We soldered.

We cut plastic whiffle balls in half, stuffed them with the electronics, a battery pack, and some bubble wrap, and tied them up with thin nylon rope. Bam! Glorb.

Besides the glorb that changed colors from red to purple to blue to reflect its acceleration, we also made a glorb that got brighter under high rotation, and dimmer under low rotation.

The Other Festival

We set four glorbs on a table in a dark room. We wanted to see what people did with them— play? explore physics?—so we did not provide any instructions or guidance, just four glowy balls.

People came in. While we didn't hear anyone explicitly discussing physics, people did pick up the balls, tossed and caught them, played around, and generally found them entertaining. Which was the goal!

I made a video showing the development of the glorbs, featuring yours truly juggling three of them. Watch it here!
