AST100: Survey of Astronomy

Undergrad course, Franklin & Marshall College, F20, F21

AST100 is an introductory astronomy course intended for students who are not majoring in physics or astronomy. This course presents an introduction to the contents of the Universe, the tools we use to study it, and the intersections of astronomy with social and political questions.

AST101: Exploring Ideas in Astronomy

Undergrad course, Franklin & Marshall College, F22, S23, F23, S24

AST101 is an introductory astronomy course intended for students who are not majoring in physics or astronomy. This course presents an introduction to the contents of the Universe, the tools we use to study it, and the intersections of astronomy with social and political questions.

AST121: Introduction to Astrophysics

Undergrad course, Franklin & Marshall College, S18, S19, S20

This course presents a quantitative introduction to our Universe: topics include the interactions of planets and moons, the formation of stars and black holes, and the evolution of the Universe from a fiery Big Bang to the expansive and beautiful array of galaxies we see today. The goals of this course are to prepare prospective astrophysics majors for upper-division coursework in the major as well as the skills to participate in independent research projects.

AST332: Galaxies & Cosmology

Undergrad course, Franklin & Marshall College, S22

Astronomy 332 provides an introduction to extragalactic astronomy and the nature of the Universe as a whole. We will discuss our own Milky Way Galaxy and its surroundings; the roles of stars, gas, supermassive black holes, and dark matter in shaping the properties of galaxies; and their evolution over time. Beyond galaxies, we will study the large-scale structure and contents of the Universe and its expansion from the Big Bang to today. Using the theoretical framework of General Relativity, we will see how the observed properties of the Universe allow us to constrain both its nascent properties and its future evolution. Throughout the course, we will also discuss the nature of astronomy and cosmology as scientific disciplines, including the way that social forces shape these disciplines and our understanding of the Universe.

PHY111: Fundamental Physics I

Undergrad course, Franklin & Marshall College, S18, F18, F20, F21, S22

This course provides a broad overview of the way objects move and interact in our physical world. We work extensively with Newtonian mechanics, including force equations, energy, momentum, and rotational motion, and we will introduce concepts of oscillatory motion including waves. In our lab sections, we experience practical examples of these ideas while also learning skills for data collection and analysis and experimental design.

PHY112: Fundamental Physics II

Undergrad course, Franklin & Marshall College, S19

Physics 112 is the second half of the introductory physics sequence. We will discuss electricity, magnetism, circuits, optics, and thermodynamics. These topics have a wide range of applications in modern physics, engineering, chemistry, and biology, so we will discuss these rela- tionships along the way! The lab section of the course will provide hands-on opportunities to explore the physics described in lecture, as well as training in data collection and analysis.

PHY226: Classical Mechanics

Undergrad course, Franklin & Marshall College, S24

PHY 226 explores the many complexities of our world that can be described by classical physics. We will discuss topics that were swept under the rug in the introductory physics sequence: air resistance, damped springs, and physics in non-inertial reference frames like our rotating Earth. We will introduce new mathematical tools including cylindrical and spherical coordinate systems, applications of differential equations, and the calculus of variations. In the lab portion of the course, we will explore the differences between discrete and analytic formulations of physical equations, and we will use computational methods to solve problems that are intractable by hand. Together, these new skills and methods will prepare you for more advanced physics and math courses and provide a window to the methods physicists use to describe our Universe with ever-increasing levels of accuracy and precision.

PHY226 lab: Computational Physics

Undergrad course, Franklin & Marshall College, S23, S24

In the computational physics lab for PHY226, we develop tools to solve physics and astrophysics problems with computers. Our class is be based on the Python programming language, but the basic methods we will be using can be applied in many other programming languages as well.

PHY333: Electric and Magnetic Fields

Undergrad course, Franklin & Marshall College, F17, F18, F19

Physics 333 provides a quantitative introduction to the physics of electromagnetism, one of the four fundamental forces of nature. Throughout this course, we will rely extensively on the tools of vector calculus to make mathematical calculations while also building a conceptual understanding of electromagnetic forces, fields, and potentials.
