PHYS 103

In this course, students will learn to use motors, relays, microcontrollers and electronic components to design and build computer-controlled devices, small robots and interactive gizmos increasingly employed in projects by artists, designers and scientists. The primary tool will be the Arduino open source microcontroller environment. Developed for use by designers, artists and hobbyists, the Arduino environment provides a wide array of options for implementing automation and interaction between a physical device and its environment. It is used in applications ranging from interactive installation art to smart home technologies and hardware control in scientific applications. The course will combine laboratory exercises, homework assignments, individual and group project work, and a culminating public presentation. No prerequisite.

PHYS 105

Gravity is at once the most familiar and most mysterious of the basic forces of nature. It shapes the formation, structure and motion of stars, galaxies and the cosmos itself. Also, because gravity affects everything, it enables us to investigate parts of the universe that are otherwise invisible to us. This course will explore the role of gravity in a few vibrant areas of contemporary astrophysics: the search for planets beyond our solar system, the discovery of giant black holes in the nuclei of galaxies, the generation and detection of gravitational waves and the evidence for dark matter and dark energy in our universe. In addition to the scheduled class lectures and discussions, students will be required to meet a few times during the semester for evening laboratories. No prerequisite.

PHYS 109

Around us we see a vast, expanding universe of galaxies. The galaxies are composed of stars, some of which planets orbit. At least one of these planets in the universe is inhabited by an astoundingly complex set of living things. Where did all this come from? This course presents an overview of the formation and evolution of the universe, the solar system, planet Earth, and life on our planet. Astronomical observations, computer simulations and laboratory experiments will supplement lectures and readings. No prerequisite.

PHYS 110

The goal of this seminar is to explore a specific topic in physics that is of current significance as well as challenging to first-year students.

The advent of widespread computing power has led to a revolution in our understanding of the natural world. Using computer models, scientists in all disciplines have been able to explore systems that are mathematically intractable. Surprising commonalities among systems have been discovered, leading to new ways of classifying phenomena and to a strong interdisciplinary perspective. In this class, students will get hands-on experience in numerical exploration using new techniques applied to many areas of science. Students will write programs to solve ordinary differential equations and to model electrical circuits, orbital motion and chemical reaction rates. In every case, students will implement these techniques in a programming language and build their programming skills. Prerequisite: SCMP 118, PHYS 270 or permission of instructor.

Oscillations of coupled bodies and normal modes of oscillations are studied along with the techniques of Fourier analysis and synthesis. We then consider waves and wave equations in continuous and discontinuous media, both bounded and unbounded. The course may also treat properties of the special mathematical functions that are the solutions to wave equations in non-Cartesian coordinate systems. Prerequisite: PHYS 240. Offered every spring.

PHYS 270

As modern computers become more capable, a new mode of investigation is emerging in all science disciplines using computers to model the natural world and solving model equations numerically rather than analytically. Thus, computational physics is assuming co-equal status with theoretical and experimental physics as a way to explore physical systems. This course will introduce students to the methods of computational physics, numerical integration, numerical solutions of differential equations, Monte Carlo techniques and others. Students will learn to implement these techniques in the computer language C, a widely used high-level programming language in computational physics. In addition, the course will expand students' capabilities in using a symbolic algebra program (Mathematica) to aid in theoretical analysis and in scientific visualization. Prerequisite: PHYS 240 and MATH 112 or permission of instructor. Offered every spring.

PHYS 345

From particle accelerators to galaxies and stars to the big bang, high-energy particle physics and astrophysics address the sciences' most fundamental questions. This course will cover topics of contemporary relevance from the combined fields of cosmology, astrophysics, phenomenological particle physics, relativity and field theory. Topics may include the big bang, cosmic inflation, the standard model of particle physics, an introduction to general relativity, and the structure and evolution of stars and galaxiesâ€™ stellar structure and galactic evolution. Prerequisite: PHYS 350 or permission of instructor. Offered every other year.

PHYS 350

In this course we develop further the basic concepts of electricity and magnetism previously discussed in PHYS 240 and introduce mathematical techniques for analyzing and calculating static fields from source distributions. These techniques include vector calculus, Laplace's equation, the method of images, separation of variables, and multipole expansions. We will revisit Maxwell's equations and consider the physics of time-dependent fields and the origin of electromagnetic radiation. Other topics to be discussed include the electric and magnetic properties of matter. This course provides a solid introduction to electrodynamics and is a must for students who plan to study physics in graduate school. Prerequisite: PHYS 245 and MATH 213. Offered every other year.

PHYS 390

Section 01 (0.25 units): In this course students will conduct research, synthesize and share experiences, attend professional presentations in the department, and present their research with oral and written presentations. Students will complete a minimum of three hours of independent research under the supervision of a faculty member as well as participate in discussion sections and other commitments as designed by the instructor. Permission of instructor required. Offered every semester.\n\nSection 02 (0.5 units): This section carries the same requirements as Section 01, except that the time commitment is six to eight hours of individual research under the supervision of a faculty member. This section represents a significant commitment to a research project. Enrollment in this section requires consultation with the department chair. Permission of instructor required. Offered every semester.

PHYS 493

Individual studies may involve various types of inquiry: reading, problem solving, experimentation, computation, etc. To enroll in individual study, a student must identify a physics faculty member willing to guide the course and work with that professor to develop a description. The description should include topics and content areas, learning goals, prior coursework qualifying the student to pursue the study, resources to be used (e.g., specific texts, instrumentation), a list of assignments and the weight of each in the final grade, and a detailed schedule of meetings and assignments. The student must submit this description to the Physics Department chair. In the case of a small-group individual study, a single description may be submitted, and all students must follow that plan. The amount of work in an individual study should approximate the work typically required in other physics courses of similar types at similar levels, adjusted for the amount of credit to be awarded. An individual study course in physics is designed for .25 unit of credit. Individual study courses should supplement, not replace, courses regularly offered by the department. Only in unusual circumstances will the department approve an individual study in which the content substantially overlaps that of a regularly offered course. Because students must enroll for individual studies by the end of the seventh class day of each semester, they should begin discussion of the proposed individual study preferably the semester before, so that there is time to devise the proposal and seek departmental approval before the established deadline. Individual studies do not count towards the QR (quantitative reasoning) requirement. If a student wishes to satisfy the QR requirement through an individual study in physics, they must receive approval through the college petition process.

PHYS 497Y

This course offers guided experimental or theoretical research for senior honors candidates. Prerequisite: permission of department chair.

PHYS 498Y

This course offers guided experimental or theoretical research for senior honors candidates. Prerequisite: permission of department chair.

SCMP 401

This capstone course is intended to provide an in-depth experience in computational approaches to science. Students will work on individual computational projects in various scientific disciplines. Each student will give several presentation to the class throughout the semester. Permission of the instructor and program director required. Prerequisite: SCMP 118 or PHYS 270, senior standing, completion of at least 0.5 units of an intermediate course and at least 0.5 units of a contributory course.

SCMP 493

The Individual Study is to enable students to explore a pedagogically valuable topic in computing applied to the sciences that is not part of a regularly offered SCMP course. A student who wishes to propose an individual study course must first find a SCMP faculty member willing to supervise the course. The student and faculty member then craft a course syllabus that describes in detail the expected coursework and how a grade will be assigned. The amount of credit to be assigned to the IS course should be determined with respect to the amount of effort expected in a regular Kenyon class. The syllabus must be approved by the director of the SCMP program. In the case of a small group IS, a single syllabus may be submitted and all students must follow the same syllabus. Because students must enroll for individual studies by the end of the seventh class day of each semester, they should begin discussion of the proposed individual study preferably the semester before, so that there is time to devise the proposal and seek departmental approval before the registrarâ€™s deadline. Permission of the instructor and program director required. No prerequisite. \n
