Growing up, math was by far my favorite subject in school. The clever manipulation of numbers exerted an irresistible attraction on me, and I soon began participating in math competitions. A few years later, I had the great privilege of taking a physics course with a teacher whose engaging classes made me appreciate the beauty of this particular science. I began to see how and why the gears of the world turned. At the same time, I took an introductory calculus course. The new concepts of differentials and infinitesimal values fascinated me, and I started to understand math on a deeper level. When I took AP Physics C, though, I finally saw the integration of higher level math and physics, and this intersection continues to enthrall me.

Having competed in math at a young age, I quickly delved into physics competitions as well. My first college-level physics textbook became my Bible; I would read it until I was too tired to read anymore, and after a quick break, I would come back for more. The new problems I encountered in difficult physics textbooks challenged and intrigued me, encouraging me to study more. I loved the feeling of enlightenment whenever I solved a problem that had stumped me for hours. As someone who loved math for its nifty tricks, I greatly appreciated a similar type of inventive thinking present in competitive physics.

I am indescribably honored and thankful to be a part of the U.S. Physics Team again, and I hope to have the opportunity to represent America at Portugal this year. I sincerely thank my 8th grade physics teacher, Mr. Singhal, for sparking and nurturing my interest in physics; Dr. Tang, for helping me continue my exploration of higher level physics; and most of all, my parents, for always supporting and encouraging me to pursue my passions.
