<p>I'm a graduate student at Stanford, studying particle physics.</p>
<p>If you're a high school student interested in physics, you should register for the <a href="https://www.aapt.org/physicsteam/2023/" rel="nofollow noreferrer">U.S. Physics Olympiad</a>, the premier physics competition in the United States. The questions for the first round are solvable with only algebra-based mechanics, and are carefully crafted to stretch your intuition and teach you new things. It's how I first got interested in physics, and how lots of curious folks every year get into it!</p>
