Physics and astronomy are fundamental sciences aimed at discovering the basic principles that govern our universe. Physicists study the interplay between space, time, matter, and energy. Complex behavior in nature is explained in terms of elementary relations between constituent elements and the forces that bind them, over distances ranging from subatomic to cosmic scale. Astronomy encompasses the entire physical universe beyond the earth: the solar system, stars, galaxies, galaxy clusters and superclusters, quasars, and the large-scale structure of the universe. The basic tools in physics and astronomy are mathematics and experimental investigation and observation of the world around us.
At Penn, the curriculum for undergraduate Physics majors, which includes extensive laboratory experience, is based on faculty strengths in Condensed Matter Physics, Elementary Particle Physics, and Astrophysics. Undergraduate teaching is linked to faculty research efforts in these areas, and participation by undergraduates in research is strongly encouraged.
This concentration reflects increasing contributions of physicists (including members of our faculty) to implications of Physics to Biological Sciences. Undergraduate students choosing this concentration will prepare themselves for careers in scientific research or professional Medical Physics programs that have been instituted at Penn and other universities, among other possibilities.
The proposed concentration is distinct from the existing Biophysics Major, although the two share several required courses. The Biophysics Major requires much more chemistry, making it appropriate for students interested in protein science and other topics within the well-established field of Biophysics. The Physics major with a Concentration in Biological Science targets students with interests in the emerging field of Biological Physics, where researchers directly apply physical concepts and techniques to investigate biological systems; the emphasis is on developing new insights regarding biological systems from a perspective strongly rooted in Physics.
The minimum total course units for graduation in this major is 36. Double majors may entail more course units.
