## COURSE CATALOGUE : PHYSICS

Historically, the discipline of physics is identified as the branch of science that seeks to discover, unify, and apply the most basic laws of nature. Our curriculum introduces students to its principal subfields—electromagnetism, mechanics, thermal physics, optics, and quantum mechanics—and provides the most extensive training in mathematical and analytical methods of any of the sciences. Since this is the foundation upon which all other sciences and engineering are based, the study of physics provides a strong background for students who plan careers in areas such as physics, astrophysics, astronomy, geophysics, oceanography, meteorology, engineering, operations research, teaching, medicine, and law. Because physics is interested in first causes, it has a strong connection to philosophy as well.

Increasingly in the modern era, physicists have turned their attention to areas in which their analytical and experimental skills are particularly demanded, exploring such things as nanotechnology, controlled nuclear fusion, the evolution of stars and galaxies, the origins of the universe, the properties of matter at ultra-low temperatures, the creation and characterization of new materials for laser and electronics technologies, biophysics and biomedical engineering, and even the world of finance.

PHYS 150 and 160 have a calculus co-requisite and are intended for students majoring in the natural sciences, or other students with a strong interest in science. Courses with numbers lower than 150 are particularly suitable for students not majoring in a physical science. Prerequisites for any course may be waived at the discretion of the instructor. Grades in courses comprising the major or the minor must average C- or better.

**BINARY ENGINEERING PLAN**

Joint-degree engineering programs are offered with Columbia University and The Thayer School of Engineering at Dartmouth College. Through these programs, in which students spend three years at Hobart and William Smith Colleges and two years at an engineering school, a student will receive a B.A. or B.S. from Hobart or William Smith and a B.S. or B.E. in engineering from the engineering school. Majoring in physics at HWS provides the best preparation for further work in most engineering fields. See "Joint Degree Programs" elsewhere in the *Catalogue* for details.

**REQUIREMENTS FOR THE MAJOR (B.A.)**

*disciplinary, 12 courses*

PHYS 150, PHYS 160, PHYS 270, PHYS 285, PHYS 383, MATH 130 *Calculus I, *MATH 131 *Calculus II, *and five additional courses in physics at the 200- or 300-level. A course at the 200- or 300-level from another science division department may be substituted for a physics course with the approval of the department chair.

**REQUIREMENTS FOR THE MAJOR (B.S.)**

*disciplinary, 16 courses*

All of the requirements for the B.A. physics major, plus four additional courses in the sciences. Only those courses which count toward the major in the departments that offer them satisfy this requirement.

**REQUIREMENTS FOR THE MINOR**

PHYS 150, PHYS 160, PHYS 270, and three additional physics courses.

**COURSE DESCRIPTIONS**

PHYS 110 ** Star Trek Physics** Can you really learn physics watching

*Star Trek*? This course says "yes." Students consider such

*Star Trek*staples as warp drive, cloaking devices, holodecks, and time travel, and learn what the principles of physics tell us about these possibilities - and what these possibilities would mean for the principles of physics. Anyone who has ever enjoyed a science fiction book or movie will find that using

*Star Trek*offers an excellent context for learning about a variety of topics in physics, including black holes, antimatter, lasers, and other exotic phenomena. (

*Offered occasionally*)

PHYS 113 **Suns and Planets** This course is designed to help the student understand the nature and process of science by studying the subject of astronomy. Specifically, this course provides an introduction to the general physical and observational principles necessary to understand the celestial bodies. We will specifically discuss what is known about our Solar System, including the Sun, the rocky and gaseous planets and their moons, and the minor planets and asteroids. The course will culminate in an overview of the discovery and characterization of planets around other stars where we will begin to put our Solar System in the context of other recently discovered exo-solar systems. (*Offered alternate years*)

PHYS 114 **Stars, Galaxies and the Universe** This course provides an introduction to the general physical and observational principles necessary to understand stars, galaxies and the Universe as a whole. We will discuss light, optics and telescopes, properties of stars, black holes, galaxies, and cosmology. The course will culminate in a discussion of the formation of the Universe starting with the Big Bang. (*Offered alternate years*)

PHYS 115 **Astrobiology** Astrobiology is the scientific study of the origin and evolution of life in the Universe. It brings together perspectives from astronomy, planetary science, geoscience, paleontology, biology and chemistry to examine the origin of life on Earth and the possibility of life elsewhere in the Universe. This course is designed to help students understand the nature and process of science through the lens of astrobiology. We will explore questions such as: What is life? How did I arise on Earth? Where else in the Universe might life be found? How do we know about the early history of life on Earth? And how do we search for life elsewhere? We will evaluate current theories on how life began and evolved on Earth and how the presence of life changed the Earth. We will review current understanding on the range of habitable planets in our solar system and around other stars. And we will discuss what life might look like on these other planets and what techniques we could use to detect it. This course is designed to fulfill a student's goal of experiencing scientific inquiry and understanding the nature of scientific knowledge. It does not count toward the major in Geoscience or Physics. (Arens, Hebb, Kendrick, *offered annually*)
