## 3D Printing at St. Mark’s: The Desktop Factory

By Varun Shankar, VI Form

3D printing—it sounds like something out of a futuristic sci-fi movie, where anyone is able to instantaneously create whatever object he or she desires, but in fact the technology is becoming more accessible today. No, we’re not able to instantly materialize anything we want yet, but 3D printing has grown from an obscure technology confined to expensive labs to a relatively cheap product for the layman. 3D printing starts with a 3D computer model of an object, made with any of the various available Computer Assisted Design (CAD) programs. The CAD file is then sent to the printer, which (more…)

## Listen To My Pictures

By Meg Josephson, VI Form

I’m going to keep this brief, or else I’d be contradicting myself.

After my constructive travels at St. Mark’s during such experiential opportunities as summer study abroad and the choir tour, I have been faced with the same pressing questions from family and friends when I return: “How was it?” and “What was your favorite part?” Once I reflect on my trip, all my memories mesh together, and the richness of the experience is so difficult to put into words. So instead, I’ve turned to the power of pictures to (more…)

## An Extension of the Arithmetic Derivative

By Seung Jae Lee V Form, Alex Padron VI Form, and Luya Wang VI Form

Instructor:  Mr. Rick Umiker, Mathematics Faculty

Abstract:  In this paper, we examine the product rule and the arithmetic derivative. We first find a closed-form formula for the arithmetic derivative over positive integers. We then extend the argument to negative numbers, rational numbers, power roots, and complex numbers. Throughout our research, we also use Mathematica graphics to help visualize the behavior of the arithmetic derivative over different domains and explore boundary conditions and intermediate lines. Finally, we discuss the continuity of arithmetic derivative and give a continuous form that satisfies the product rule. (more…)

## Dream Failures: Both Gatz and Gatsby

By Jack Gorman, V Form

The American Dream is an imperfect concept. It is also individual. James Gatz and Jay Gatsby had different American Dreams in the novel The Great Gatsby. While James Gatz wanted to be rich, famous, and among the elite, Jay Gatsby discovered a new journey. His heart was set on Daisy. But, while Jay Gatsby was lusting after his would-be lover, Gatz fell into the shadows. What about his American Dream? Gatsby let his new persona’s dreams overpower his original dreams and in doing so makes a terrible mistake. He took a successful concept and shattered it. He took the prizes of his effort and devalues them. So who really lived their American Dream, Jay Gatz? Or James Gatsby? (more…)

## Getting My Hands Dirty Again

By Jeanna Cook, Classics Faculty

This summer, I will fulfill a promise that I made to myself eight years ago.  In the summer of 2006, I spent a season excavating at the site of a first-century Roman farmhouse outside of Lucca, Italy. I loved every moment of that summer, and upon the conclusion of the excavation, I promised myself that once I completed my undergraduate studies, found a job, saved some money, and earned my graduate degree, I would go back to digging. This summer, I am returning to the field, the archaeological field, that is. (more…)

## Why I Do Not Grade “Class Participation”

By John Camp, English Department Head

I am a vehement opponent to class participation grades.  I am fully cognizant that I am in the minority in my department, perhaps at St. Mark’s at large, and even in the teaching profession.  Despite the self-imposed peer pressure to grade for this, I refuse, based on both my life personally as an introvert (and the value I place on my introversion as a healthy and necessary part of my identity) and my pedagogical beliefs about participation overall.
