Computer Science is the science of algorithms — their theory, analysis, design and implementation. As such it is an interdisciplinary field with roots in mathematics and engineering and applications in many other academic disciplines. The program at Bryn Mawr is founded on the belief that computer science should transcend from being a subfield of mathematics and engineering and play a broader role in all forms of human inquiry.
Computer Science is a bicollege program, supported jointly by faculty at both Bryn Mawr and Haverford Colleges. The program welcomes students who wish to pursue a major in computer science. Additionally, the program also offers a Minor in Computer Science, a Concentration in Computer Science (at Haverford College) and a Minor in Computational Methods (at Bryn Mawr College). The program also strives to facilitate evolving interdisciplinary majors. For example, students can propose a major in cognitive science by combining coursework from computer science and disciplines such as psychology and philosophy.
All majors, minors and concentrations offered by the program emphasize foundations and basic principles of information science, rather than engineering or dataprocessing applications. Both colleges believe this approach to be the most consistent with the principles of scientific education in the liberal arts. The aim is to provide students with skills that transcend shortterm trends in computer hardware and software.
Independent Major in Computer Science
Students who wish to major in computer science do so by declaring an independent major. Students are encouraged to prepare a major course plan in consultation with their academic adviser in computer science. A typical course plan includes three introductory courses (110 or 205, 206 and 231), three core courses (240, 245 and one of 330, 340 or 345), six electives of a student’s choosing and a senior thesis. Students declare an independent major in the spring semester of their sophomore year. Such students should ensure that they have completed at least three courses in computer science by the end of their sophomore year (we highly recommend 110, 206 and 231).
Minor in Computer Science
Students in any major are encouraged to complete a minor in computer science. Completing a minor in computer science enables students to pursue graduate studies in computer science, in addition to their own major. The requirements for a minor in computer science at Bryn Mawr are 110 or 205, 206, 231, any two of 240, 245, 246, 330, 340 or 345, and two electives chosen from any course in computer science, approved by the student’s adviser in computer science. As mentioned above, these requirements can be combined with any major, depending on the student’s interest and preparation.
Minor in Computational Methods
This minor is designed to enable students majoring in any of the sciences (biology, chemistry, geology, physics, psychology), mathematics, economics, sociology, philosophy, archaeology and growth and structure of cities to learn computational methods and applications in their major area of study. The requirements for a minor in computational methods at Bryn Mawr are 110 or 205, 206, 231; one of 212, 225, 245, 246, 330, 340 or 361; any two computational courses depending on a student’s major and interests (there are over 35 such courses to choose from in biology, chemistry, computer science, economics, geology, mathematics, physics, psychology and sociology).
Students can declare a minor at the end of their sophomore year or soon after. Students should prepare a course plan and have it approved by at least two faculty advisers. Students minoring in computational methods are encouraged to propose senior projects/theses that involve the application of computational modeling in their major field of study.
