Indecision was the hardest part of my college application process. Which college do I want to attend? What major should I choose? Despite assurance from adults in my life that it was okay to start off college as undecided, I felt pressure to figure out what degree I wanted to pursue. Suppose after deciding on a major, I found out the college I had chosen didn't offer it? But it was very hard to nail down what degree to pursue when I was considering everything from engineer to author to translator. Feeling pressured by scholarships that required a declared major, I eventually narrowed my choices down to engineering, where I still felt I had plenty of options. Would I rather be a civil engineer? I could help build the new idea of smart cities and find greener ways to make a building. Or would I rather be an electrical engineer? It sounds like fun to solve problems with circuits, like a puzzle that does the world good when finished. Or should I consider becoming a chemical engineer? "Chemical engineers can do a little bit of almost anything," someone once told me when I mentioned I was considering it. That statement is what really sold me on declaring that my major, if I'm being honest. Sure, I liked chemistry in high school, but there were plenty of other subjects I liked. Despite being inspired by a friend who was studying chemical engineering and a mentor who said it was right up my alley, I wasn't sure I wanted to follow in their footsteps. Part of me even held on to the idea that I could switch my major at any time. Chemical engineering was just a stepping stone to get me into the engineering department. Then I could decide what I really wanted to do. But more than any of those things, I chose to pursue chemical engineering hoping that one phrase would be true, that I could do almost anything.
I'm glad to say that studying chemical engineering did not disappoint. I've moved on from liking chemical engineering for how it allows and aids my indecisiveness to liking chemical engineering for what it is. I've fallen in love with my chemical engineering classes, and I wouldn't change a thing about my major. One of my new favorite things about chemical engineering is being able to use my degree to have a positive impact on the environment. Human history has shown a transition from living off the land to materialistic societies that don't always use the most environmentally-friendly resources. More recently, new solutions that use resources more responsibly without sacrificing performance have been discovered. Chemical engineering, and more specifically material science, is an important part of developing these new solutions. When getting involved in undergraduate research, for example, I looked into many research projects. One of my professors had research looking into new and improved vaccines, ones that require less preparation time. Another professor had a project involving nano-particles. Her research is important for understanding how nano-particles in medicine behave in the body and how nano-particles in fertilizer affect plants. Since some nano-particles are too small to be processed by certain organisms, they can build up to dangerous levels. This professor's research helps explain this process and prevent that from happening. The research that I, personally, became involved in was synthesis of silica aerogels. Aerogel is an interesting substance because it is transparent (letting light through), but insulating (not letting heat through). This is a rare combination of properties, and it could revolutionize architecture as we know it. A building full of windows is a beautiful sight, but glass is not an ideal insulator. The majority of heat produced in a building is lost through the windows, and windows can't be replaced because other transparent materials have the same issue. Replacing windows with aerogel, or a combination of aerogel and glass, would allow windows to stay transparent without sacrificing lots of heat lost to the environment. Not only could this save the owner of the building money that would be spent on more heat, it also means less fossil fuels are burned to produce that heat. Aerogel is also useful to convert solar energy to thermal energy. This is a completely renewable way to produce heat, so once again, less fossil fuels will be needed. While these examples are my own experience with environmental applications of chemical engineering, there are plenty of others. Chemical engineering may be the key to longer lasting batteries, more recyclable materials, and better medications. I may have narrowed my options in committing to a major, but my chances to change the world are still as wide as ever.
