WYETH RENWICK, A PROOF OF THE FUNCTION ME

Wyeth Renwick’s poem is intriguingly ambiguous and open to interpretation: some
of the judges read it as a love poem that winks at the reader with its use of
mathematical concepts and language, while others saw it as a poetic animation of
a human relationship, viewed as the graph of a function.  Either way, it makes
math and poetry both seem more accessible to students who might otherwise not be
drawn to these subjects.

Cole Leis, On the Importance of Humanizing Math Communication

Cole’s project was an essay about “a disconnect between the way math is
typically portrayed and the way that it is actually done.” Math textbooks and
papers usually try to look flawless, but anyone who does math knows how messy
and confused it can be when you’re actually doing it. Cole interviewed several
mathematicians about this disconnect and produced a cogent argument that math
communication would be more effective if we humanized it by showing our mistakes
as well as our insights.

“us”) is from another source, in this case the MathWorld article by Eric
Weisstein on “Fundamental Theorems of Calculus.” Helena rearranged the words to
create something totally unexpected, an understated little poem that took the
judges’ breath away.

Shreya Mogulothu and Amy Wang, Combinatorial Proofs... and Basketball

Shreya and Amy teamed up to bring a combinatorial identity to life. Using
basketball as a mathematical playground, they showed two approaches to
calculating how many ways a player could make or miss n shots, and thereby
neatly led the viewer through a proof that the sum of the binomial coefficients
“n choose k” from k = 0 to n equals 2^n. The video is goofy and fun: Amy writes
(and playfully trash-talks) while Shreya shoots and, before you know it, they’ve
derived the identity for the sum of the binomial coefficients. The judges
enjoyed the simple but clever videography, the banter between the girls, and
their neat explanations of the math.

Julia Schanen, Math Person

Julia Schanan’s entry for the Strogatz Prize was a free-verse poem titled “Math
Person.” The judges were moved by the poem’s artistry and emotional power, its
depth and raw honesty, its brilliant use of language, and its eye for the
unexpected but telling detail. “Math Person” conveys – in ways both beautiful
and haunting – the isolation Julia felt as one of the only girls in the American
Math Competition 10th grade and, more profoundly, the intellectual isolation she
still feels every day as someone who loves math deeply yet lacks a friend with
whom to share it.

Mom offers to stop by Panera as a treat for all the painful math that I’ve just
endured.

Except it wasn’t painful.

I’m someone who sat through the slow-drip of middle school math, bored and
daydreaming,

not seeing what it was all for, wishing – but never working up the guts to push
– for more.

Not until now.

Now, I don’t want Panera.

I don’t want to be patted on the shoulder and misunderstood.

I want to go back into that auditorium and finish the exam and talk about it all
night.

The judges felt that their own words were inadequate to summarize Julia’s
achievement in writing “Math Person.” Let us simply say, read her poem and
experience it for yourself.

Apoorva Panidapu, Gems in STEM

Apoorva Panidapu is a 16-year-old mathematics student, artist, and advocate for
youth and gender minorities in STEAM. She writes a blog called “Gems in STEM”
and frequently posts the essays on Cantor’s Paradise, the #1 math site on
Medium.com.  She sees her blog as “a place to learn about math topics in an
accessible, light-hearted manner. I assume no more than basic math knowledge and
include fun tidbits for learners of all experience levels. For both my own fun
and for readers, I weave in pop culture, pick-up lines, and over-the-top stories
to let people into the fantastical world of math, and to show them that anyone
can enjoy anything.”

The judges were very impressed with Apoorva’s joyful, elegantly written blog
posts on a wide range of math topics, from the liar’s paradox and partitions to
tessellations and fractals. Combining clear explanations with an appealing
layout and well-chosen graphics, Gems in STEM is itself a gem. The judging panel
loved the wide range of Apoorva’s blog posts. They touch on history, etymology,
and puzzles, and make connections to everything from art and architecture to
science and nature. Apoorva’s uplifting message is that math is everywhere and
approachable by anyone from any background.

Shirley Zhu, Combinatorics: Sticks and Stones

Shirley’s animated video is filled with jokes and pop-culture references,
intended to appeal to younger audiences (though the audience of older judges
enjoyed it very much too). Her goal, she says in her essay, is to demystify
“mathematics with humor, fun animations, and real-world scenarios.” In her
video, Shirley illustrates a technique in combinatorics known as Sticks and
Stones (or Stars and Bars) by telling a story about Grandpa Bob’s dilemma:  He
wants to know how many different ways there are for him to distribute 10
one-dollar bills among his three granddaughters. With excellent pedagogy
(including falling into a tempting mathematical trap and then showing how to get
out of it), the video shows the viewer how to count all ways Grandpa Bob can
solve his problem. The video is fun and fast-paced, but spends just the right
amount of time on the harder ideas and leavens them with colorful graphics and
word choice.

Catherine Stanton, Understanding Set Theory

Catherine’s video was inspired by her struggle to understand why the empty set
is a subset of every set. As she wrote in her essay for this contest, “I’ve
never been one to accept or memorize a mathematical concept unless it makes
complete sense to me, so I decided to go beyond sheer numbers and create an
analogy. I realized that the sets on my page could be related to my classes at
school. As the elements of a mathematical set are numbers, the elements of a
class are students. When some are absent, only a “subset” of the class exists.
And when all are absent, a subset of the class still exists since the class
period still technically occurs. This analogy wasn’t something I wanted to keep
to myself, and so it became the basis of my entry to the Strogatz Prize
competition!”

The judges appreciated Catherine’s lucid explanations and accompanying graphics.
Set theory is often regarded as one of the most abstract parts of math, but in
Catherine’s hands, it becomes tangible and vivid. Her classroom analogy should
appeal to any student. Beyond that, Catherine gives the viewer a glimpse of the
universality of set theory and a taste of its applications in computer science.

Smayan Khanna, 4 Colour Map Theorem

In this video about a famous theorem in graph theory and topology, Smayan
beautifully explains why every planar map can be colored with just four colors,
in such a way that neighboring countries always have different colors. The video
is gentle and clear, and enlivened by plentiful graphics, neatly synchronized to
Smayan’s narration. He gives the viewer helpful intuition about how inequalities
(for vertices, edges, and faces of planar graphs) can be used to cut a seemingly
infinite problem down to a finite number of cases, which can then be checked by
computer. The judges felt that this was a very crisp presentation of a deep
result in advanced mathematics, explained in a way that anyone can grasp and
enjoy.

Fun with Mathematical Definitions

Is an elevator a vehicle?  Is a hot dog a sandwich?  Is a heart a shape?  Is an
emoji a word?  The answers to these questions depend on your definitions of
vehicle, sandwich, shape, and word.  Precise definitions are essential tools of
mathematics, but few definitions start out as precise as they’ll need to be
later on.  Come play with the boundary between precision and ambiguity in this
fast-paced participatory session.

Rohan Jha

LIVINGSTON, NJ

--------------------------------------------------------------------------------

“The purpose of Math Musings, the magazine I started in high school,” wrote
Rohan Jha,  “was to show that math is everywhere, yet many times we are not
aware of it.  It is behind some of the music we play, or how nature uses it for
its own optimal benefit, or it could be behind a fancy card trick, or math could
help us reduce the ubiquitously observed annoyance of traffic jams during peak
hours.”  The magazine tries to humanize and enliven math in various ways: by
telling anecdotes about famous mathematicians; by challenging fellow students
with fun puzzles; or by leading them some deeper ideas, such as a lily pad
puzzle that leads to the notion of backward recursion in finance.  With clear
illustrations and step-by-step instructions for magic tricks and other
activities, Rohan attempts to make math fun for everyone… and succeeds
admirably.

Kyna Airriess

CORONADO, CA

--------------------------------------------------------------------------------

The project submitted by Kyna Airriess is a “zine” based on a quote from A
Mathematician’s Lament, a polemical essay by high school teacher Paul Lockhart.
 “There is nothing as dreamy and poetic, as radical, subversive, and
psychedelic, as mathematics,” wrote Lockhart.  Reading Lockhart’s essay, says
Kyna,  “contributed to my own conversion from ardent math-hater to aspiring
mathematician; I’d never heard someone describe math, the subject of unfeeling
calculations, with words like ‘poetic’ and ‘radical.’  It was a long time before
I began to see these traits for myself, but today I self-identify as a math
nerd, and I want to study math in college.”

In the zine, each of Lockhart’s memorable adjectives—dreamy, poetic, subversive,
and psychedelic—is illustrated and connected to math ideas, using symbols,
history, color, and imagery.  The judges were impressed by the passionate energy
conveyed by the zine’s words and design.  The overall effect achieves what Kyna
intended:  to embody “what those of us who love math want the world to
understand. It isn’t about cold calculations at all— it’s a field full of
creativity and beauty, and it is just as infused with humanity as any other.”

Sarah Thau

 NEW YORK, NY

--------------------------------------------------------------------------------

“Limericks and poetry are not a typical way to convey information about math,”
admits Sarah Thau, “but I think it makes it more palatable than learning
functions by rote.  Who doesn’t love a limerick?”  So Sarah created a series of
short rhyming poems to list some basic properties of linear, quadratic,
trigonometric, polynomial, rational, and other types of functions encountered in
algebra and precalculus, and illustrated the pages with examples.

The judges were tickled by the playfulness of this entry.  Limericks are a
lighthearted form of poetry in which creativity comes from working within
constraints and overcoming them delightfully—and much the same can be said of
math!  Indeed, as Sarah wrote, “I love math and am always trying to solve
problems but this was a new type of problem to tackle.  One that didn’t need any
algebra or modeling.  Each poem became a problem to solve as I tried to figure
out words to make each function type’s properties rhyme neatly.”  The poems
illuminate the distinctive properties of the various kinds of functions, and
draw readers in through a unique, creative, and memorable way of communicating
mathematical ideas.

Jonah Yoshida

HONOLULU, HI

--------------------------------------------------------------------------------

Jonah Yoshida’s project is a pencil-and-paper infographic on graph theory.  He
says “I conceived of the idea when reading about how Arthur Cayley used trees to
represent structures of hydrocarbons with n carbon atoms and 2n+2 hydrogen
atoms.  The entire structure imitates one of these hydrocarbons, ethane (n=2),
and a unique application of graph theory is included inside each atom.  I
divided the page into two sections so that the hydrogens bonded to the left
carbon contain puzzles and fun applications of graph theory, while the ones
bonded to the right hydrogen focus more on direct applications, much like our
brains’ left and right hemispheres.”  For example, the Four Color Theorem (a fun
application of graph theory to coloring maps and an longstanding research
question) appears on the left, while the right side includes applications of
graphs to computer science (neural networks and spanning trees) and electrical
engineering (circuit diagrams).

The judges appreciated the ingenious design concept of this graphic, which
underscores the  universality and interdisciplinary spirit of graph theory.  The
words and imagery combine history, math, chemistry, and psychology, and the
questions in the small text boxes invite the reader to do some research of their
own.

Yvonne Hong

TORONTO, ON

--------------------------------------------------------------------------------

“My math communication project, Infinity Universe,” wrote Yvonne Hong,  “is an
illustrative yet mathematical depiction of the world in which we live.  Every
inanimate object illustrated represents a simple, yet ubiquitous concept in
math: upon closer inspection, the monochromatic tree is a fractal Pythagoras
tree, the galaxy in the background is constructed using the Fibonacci sequence,
and the planet and comet are both different variations of the Apollonian gasket.
 Infinity Universe promotes the universality of math communication through an
abstraction of objects and phenomena that people all around our world are
familiar with.”

Carefully executed with great attention to detail, the painting submitted by
Yvonne drew the judges in with its vibrant colors and hypnotic patterns.
 Moreover, the theme of infinity pervades the painting, just as it does in all
of mathematics.  But here, the suggestion of the infinite is magical and
otherworldly rather than scientific and literal, and so may appeal to audiences
not normally attracted to math.

Zoe Markman

NEW YORK, NY

--------------------------------------------------------------------------------

Zoe Markman created a visual proof of the “sum of squares formula” by cleverly
using three wooden 3-D pyramids that fit together.  Each pyramid consisted of a
total of 12 + 22 + … + n2 identical wooden cubes; thus, its volume visually
represented the sum of the squares of all the whole numbers from 1 to n.  To
find a formula for this sum of squares, Zoe manipulated and rearranged the three
pyramids to form a rectangular prism, whose volume could then be easily
calculated to obtain the desired formula for the sum of squares.

The judges agreed with Zoe that this sort of visual, hands-on manipulative
“provides a deeper understanding of math than that provided by a written
project.  Since you can observe, hold, and manipulate the pyramids (even more so
in person), the audience is able to understand why the formula works rather than
just taking it at face value and accepting that it was true arbitrarily.
 Second, the presentation could be understood even by people without a
significant knowledge of math.  It put what looks like an intimidating problem
in terms that are easily digestible.”  Zoe even tested the presentation on
friends who said they didn’t like math.  That’s a good practice in any form of
communication.  Overall, this project is modest but extremely well done and
produces a very pleasurable “Aha!” moment for many viewers; indeed, it led one
of the judges to understand the “sum of squares formula” in a whole new way!

Katarina Cheng

SANTA MONICA, CA

--------------------------------------------------------------------------------

To express the universality of math, Katarina Cheng translated it into another
universal language: dance. “Just as dance exists as a part of many cultures
around the globe to express abstract ideas and emotions through movement,
mathematics defies cultural lines to express abstract ideas through structures
and forms on the page,” she wrote in her project description. Her video “Dancing
the Dihedral Group” sought, through dance, “to represent the visual symmetries,
primarily those of a square,” and, through words, “how they translated into
algebra, primarily the group D8 .”

The judges commend Katarina for the elegance of her communication in the video.
Especially notable was the esthetic of minimalism — in how the video is shot,
and the choice of clothing, background, and colors — all of which mesh perfectly
with the minimal esthetic of group theory. The integration of the math graphics
with the dance moves was also carried out gracefully. Although others in the
past have recognized the similarities between math and dance, few have conveyed
that analogy with such finesse in the execution. The dancing and music were
artfully minimal too. The overall effect is to reinforce the central idea of
beauty in simplicity.

Hamza E. Alsamraee

CENTREVILLE, VA

--------------------------------------------------------------------------------

Hamza Alsamraee loves Instagram – and he also loves math. But when he noticed
that very few math pages existed on Instagram, he sought to change that by
starting @daily_math, a page dedicated to intriguing problems and ideas about
algebra, geometry, calculus, number theory, and other parts of math. “With
high-quality educational posts,” he says, “I hoped to build an Instagram
community centered around a shared passion for math.”

The judges were impressed with the creativity of Hamza’s entry, expressed
through its skillful use of visuals, history, and puzzles, all presented in
attractive ways. His explanations of mathematical concepts are clear and
insightful, and he is very interactive with his followers, even inviting them to
post. The judges also commend him on his growth as a creator and communicator.
His Instagram page has evolved from a focus on tricky integrals in the early
days to doing more accessible problems now, and the visual presentation has
evolved in tandem. With his engaging design choices, which foster clear
communication, he is making increasingly good use of the strengths of the
Instagram medium.
