Computer Vision: Mapping Poverty in Uganda
This summer, I attended an all-girls program called Ai-4-ALL, formerly known as SAILORS (Stanford Artificial Intelligence Laboratory’s Outreach Summer Program). Inspired by the camp’s model “AI will change the world. Who will change AI?” I believe that people, instead of perceiving artificial intelligence (AI) as threats, should use it as a tool for impact. During this camp, I, along with seven other AI-enthusiasts, created a model for mapping poverty using satellite images. (more…)

The Art of Summation—An Introduction to Infinite Series
No matter if you like math or not, or if you are good at it or not, take a look at this for fun, and see how far you can get. If you are stuck somewhere, skip it and move on. If you think some parts are too easy and obvious for you, just bear with me. Today, I’m graduating from St. Mark’s, and this is probably my last time (maybe even the first time) catching your attention. I promise you’ll discover something deeply mesmerizing about math. Let’s start with some definitions. In mathematics, a series is the sum of a sequence of numbers. Imagine that you are given a sequence, say 1, 2, 3, 4. Then 1 + 2 + 3 + 4 = 10 is a series. Now it’s easy to extend this definition to infinite series, which is simply the sum of an infinite sequence of numbers that never ends like the example above does. An infinite series is convergent if the sum
of its terms is a finite number, and is divergent if the sum reaches infinity.
Infinite series is one of the most beautiful and delicate mathematical objects in my world.

Software Pipeline Connecting Close-Range Photogrammetry and 3D Printing
The aim of this project is to make it possible for an average person with no prior knowledge in photogrammetry to 3D-print small objects found in daily lives. My work is to create a software that serves as a pipeline; the software connects the multiple processes that are required to transform the input of of photos of the target object into an output of a 3D printable model file. In other words, what used to be a complicated process of switching between different tools and manually processing the model to make it 3D printable becomes a simple one-click routine where the user can provide the initial group of photos, and then simply sit next to the 3D printer to wait for the object to come out half an hour later.

“Two Worlds”–Drawing with Color Pencil and Gouache
Made with color pencil and gouache (a type of paint) on bright orange paper, this drawing is called Two Worlds. It examines pollution, part of my concentration topic for my Studio III portfolio. I approached the subject from a third person perspective. Inside the apartment, a couple sits comfortably, while outside is a polluted world which animals have to escape. The depiction reveals a discrepancy between human and animals’ experience with pollution. We never realize the price the ecosystem paid for us to enjoy our daily conveniences, such as having electricity and running water. Additionally, since our general public regard pollution as distant and irrelevant, we often made little effort to change. Nevertheless, to accept a polluted world is our selfish decision, negligent of not only the future of humanity but also of the entire ecosystem. (more…)

Autism-Vaccine Controversy: Video
Editors’ Note: In Advanced Biology, students were encouraged to tell the story that they felt compelled to relate about their Public Health issue (click here for assignment). In this video, the students integrated a given Case Study with relevant information gathered through independent research. Their integration of the Case Study with additional research reflects an advanced understanding of, and ability to convey, scientific content.
