Physics and Earth Science

Chair: Associate Professor Krieble
Associate Professor: Roeder; Assistant Professor: Malenda; Adjunct Faculty: Becker, Edinger, Jackson

The Physics and Earth Science Department provides an opportunity to investigate and study those areas of physics essential for graduate work in physics or for a physics-related career in industry, government, or secondary education. In the physics curriculum, the emphasis is on theoretical developments and problem-solving at the appropriate level of mathematical sophistication; and on experimental investigation that stresses physical principles and that makes use of modern laboratory techniques and equipment.

Throughout the curriculum, extensive use is made of the College's computer facilities for solution of physics problems and analysis of experimental data. Departmental facilities include research equipment for independent study and Honors work and a complete machine shop to supplement experimental projects.

A booklet prepared by the Society of Physics Students (SPS) describes the department and its facilities and is available from the department chair upon request.

The department offers introductory courses in geology, astronomy, and meteorology. A major in geology is offered through cross-registration in cooperation with Lehigh University. Because the study of geology is an effort to understand natural phenomena on and within the earth, a student of geology must have a broad understanding of the basic sciences and mathematics, as well as professional courses in the geological sciences.

Learning in Common Requirements for Physics Majors

Physics majors must select Mathematics 170 to fulfill their Quantitative Reasoning (F2) requirement and Physics 111 for their Laboratory Science (F4) requirement. In addition, they need complete only seven of the eight Multidisciplinary and Upper-Division requirements.

The Major in Physics

The Physics and Earth Science Department offers two degree options for students wishing to pursue the physics major: The bachelor of arts (B.A.) and the bachelor of science (B.S.). The requirements for each degree option are listed below.

The Bachelor of Arts with Major in Physics

The bachelor of arts with a major in physics consists of 7 course units in physics (Physics 111, 112, 222, 331, 345, and two additional 300-level courses) plus four course units in mathematics (Mathematics 170 or 106-166, plus 171, 211, and 221). It is suggested that the student schedule Physics 111-112 in the first year and begin mathematics at the calculus level by scheduling Mathematics 170 and 171 in the first year, if possible. In the sophomore year, the courses normally taken are Physics 222 and Mathematics 211 and 221.

The Bachelor of Science with Major in Physics

The bachelor of science with major in physics consists of 10 course units in physics (Physics 111, 112, 222, 331, 341, 345, 346, and three additional course units), plus five course units in mathematics (Mathematics 170 or 106-166, plus 171, 211, 221, and 327). If the student chooses Physics 343 as one of the three elective physics courses, he or she may omit Mathematics 327. It is strongly recommended that the student schedule Physics 111-112 in the first year, and begin mathematics at the calculus level by scheduling Mathematics 170 and 171 in the first year. In the sophomore year, the courses normally taken are Physics 221 and 222 and Mathematics 211 and 221.

The Minor in Physics

The minor in physics consists of five course units including either Physics 109-110 or Physics 111-112 but not both.

The Interdepartmental Major in Physics

The student interested in a career requiring an interdisciplinary science major is encouraged to design an interdepartmental major in physics and is urged to consult the department chair.

The six courses that satisfy Set I of an interdepartmental major in physics are Physics 111-112 and any four upper-level courses in physics. These courses and the six of Set II are selected by the student with the approval of the department chair. An interdepartmental major in physics and mathematics is strongly recommended for any student wishing to prepare for a teaching career in physics.

The Major in Geology (cooperative)

A major in geology consists of Mathematics 170 and 171, Computer Science 120, Chemistry 113-114, Physics 111-112, Earth Science 110, and seven additional geology courses to be taken at Lehigh University, one summer at a geology field camp (to be taken at an approved college or university field camp), and two courses in further science or mathematics selected with the approval of the major advisor. As with physics majors, geology majors take seven of the eight Multidisciplinary and Upper-Division courses in the Learning in Common curriculum.

The Minor in Earth Science

The minor in earth science consists of five course units: Earth Science 110, 120, and 130, plus two courses that may be taken through independent study or cross-registration.

The Interdepartmental Major in Earth Science

Set I requirements include Earth Science 110 at Moravian and five earth science courses, selected with the approval of the Set I advisor, at Moravian or Lehigh University. Students who plan an interdepartmental major should keep in mind that the earth sciences require a well-rounded background in mathematics and the basic sciences.

Departmental Recommendations

A student planning a major or an interdepartmental major in physics should discuss career plans with the department chair, because such plans influence the choice of the elective physics courses, the modern language courses (French, German, or Russian is recommended), elective mathematics courses, and any other elective courses (e.g., astronomy, geology, chemistry, or biology). These considerations are especially important for a student planning graduate work in physics or teaching at the secondary level.

Students seeking secondary school teacher certification in physics follow either the requirements for the physics major or those for the interdepartmental major, with physics constituting Set I and mathematics constituting Set II. Students also must take Chemistry 113. Those interested in combining physics and general science certification should consult the requirements for such certification under science education. All students seeking certification in secondary education should consult the Education Department.
