Caltechs supplemental essays are so intimidating

Last summer, I conducted environmental research focused on forest management across California redwood forests. Through this experience, I was able to bear witness to the great beauty that lies in these ancient, towering trees. Beyond their beauty, though, I was taken aback by how much there was to learn from them. My curiosity was sparked throughout my time as a researcher as I learned more about redwoods, from their remarkably high bark moisture content that makes them fire-resistant to their incredible carbon sequestration abilities. This experience taught me that, in a society where humans are often prioritized over other living things, it is essential to raise awareness for the well-being of plants and animals, including the underlying wisdom they provide. Through Caltech’s Environmental Science and Engineering program, specifically exciting classes like “Forest Ecology” and “Climate Science,” I hope to continue pursuing this curiosity about the natural world and to equip myself with the skills necessary to create solutions to environmental challenges that keep the needs of both humans and plants in mind.

You don't aspire to attend Caltech if you don't have big ideas and the nerve to test them out. What have you created, invented, or innovated? What have you come up with that no one else has, whether it’s an actual invention, an idea, a process, or something else? It might be that gadget you dreamed up and hacked out the prototype for late one night. Or the improved method you developed for your team to document and share its collaborative research. Or maybe it was the summer you decided to teach yourself a new skill for each of 67 days. Think of a time you didn't just build code in CS or work on a team in robotics, but you actually innovated—changed something for the better or brought something new into the world.
