Hello everyone! I've been a member of the Physics Forums for well over a year now, but this is the first time I've ever posted. I will be starting my undergraduate education this August at the Illinois Institute of Technology with the intentions of majoring in physics. Thanks to all of the AP credits I amassed in high school, I will be able to graduate one year early. However, I received a full-tuition scholarship, so rather than wasting that 4th year of a free education, I want to fill up my schedule and major in a second subject. I'm not quite sure what that subject should be, though. I love physics and I hope to become an experimental physicist, probably in the high energy particle physics field. For that reason, I want my second major to be relevant and helpful towards that ambition. Here are three of the double majors I'm considering -- along with the school's descriptions -- that I feel will benefit me the most: Applied Mathematics Applied mathematics is the mathematics that is created in response to problems in science, engineering, and society. Applied mathematicians work on a wide variety of topics such as how to construct methods for multicriteria decision making (requiring discrete mathematics and statistics), predicting how the financial markets will behave (requiring probability/statistics, analysis, optimization), and analyzing how liquid flows around solids (requiring expertise in computational methods and analysis). Computer Information Systems The Bachelor of Science in Computer Information Systems emphasizes the use of computers as sophisticated problem-solving tools. Students in this program pursue an interdisciplinary course of study that combines a solid foundation in computer science with a focus in another discipline. This program is designed for students who seek to blend their computer science abilities with skills specific to another domain to solve problems in that domain. Examples include computing with a business focus (e.g., management information systems) and computing with a natural science focus (e.g., computational physics). Computer Science The Bachelor of Science in Computer Science (BSCS) program focuses on the concepts and techniques used in the design and development of advanced software systems. Students in this program explore the conceptual underpinnings of Computer Science—its fundamental algorithms, programming languages, operating systems, and software engineering techniques. In addition, students choose from a rich set of electives that includes computer graphics, artificial intelligence, database systems, computer architecture, and computer networks, among other topics. As with the introductory sequence, these advanced courses stress "hands-on" learning by doing. I'm leaning towards Computer Information Systems, although I think that I would enjoy Computer Science the most out of those options. I still haven't met with my counselor and finalized my schedule, so nothing is too late or out of question. I'm open to all suggestions, comments, and criticisms, and I really appreciate any input you may have!
