# Physics and Astronomy

## Learning Goals

- Demonstrate the ability to use basic mathematical tools (algebra, basic differential and/or integral calculus, trigonometry, geometry) to describe physical situations, whether experimental or theoretical (all sub-1100 courses focus on this).
- Explore the relationship between physical theory and experiment through mathematical descriptions and instrument-based verification.
- Improve understanding of physical law through the ability to solve increasingly complex problems in physics with more complex mathematical tools (multivariate calculus, differential equations, linear algebra, and more complex math tools).
- Use sophisticated instrumentation and computation to explore physical phenomena.
- Improve understanding of uncertainty and its key role in defining how we know what we know.
- Expand theoretical, computational, and experimental toolkit through 3000-level methods curriculum.

### Information for Incoming Students

Physics has a placement test to help determine which entry-level course in the physics sequence is the appropriate starting point for each student.

Topical physics courses, which many students choose out of general interest in physics or to satisfy college distribution requirements, do not require a placement exam. PHYS 1510 Introductory Astronomy is open to all students interested in the ideas of physics and their impact on our built and natural world.

PHYS 1130 Introductory Physics I and PHYS 1140 Introductory Physics II, both offered every semester, provide students with physics tools that support their future work in STEM majors and career fields. PHYS 1093 Introduction to Quantitative Reasoning in the Physical Sciences can help prepare students for the pace and intensity of these introductory courses.

Students cannot enroll in PHYS 1093 Introduction to Quantitative Reasoning in the Physical Sciences or PHYS 1130 Introductory Physics I without taking the placement test. If a student has not completed the on-line physics placement test prior to arriving on campus, they should contact the department to complete the placement exam as soon as possible to be able to register for introductory physics at Bowdoin. The only introductory students who are exempt from the placement exam are students who submit qualifying official scores on AP (4 or 5) or IB (6 or 7) exams to the Bowdoin Registrar and those who transfer college credits in physics to Bowdoin. Please e-mail Emily Green if you have questions about placement or testing.

The three entry point options to the introductory physics sequence are:

PHYS 1093 Introduction to Quantitative Reasoning in the Physical Sciences develops applied mathematical and physical reasoning skills. This course focuses on improving independent problem-solving skills and STEM literacy with individualized support. Students learn how to build upon and apply quantitative skills that they already have to problem solving for the physical sciences. This course works very well in conjunction with another introductory STEM course in the first college semester, including CHEM 1091 Introductory Chemistry and Quantitative Reasoning I or CHEM 1101 Introductory Chemistry I. It satisfies the Mathematical, Computational and Statistical Reasoning (MCSR) distribution requirement. There is no math prerequisite for enrollment in this class.

PHYS 1130 Introductory Physics I is the first semester of a two-part, calculus-based physics sequence. This course in Newtonian Mechanics with laboratory. It is

required for all physics, biochemistry, chemistry, and chemical physics majors, and for pre-medical, pre-health, and pre-dental students. This course can satisfy

either the Mathematical, Computational and Statistical Reasoning (MCSR) distribution requirement or the Inquiry in the Natural Sciences (INS) distribution requirement. Mathematics prerequisite: concurrent enrollment in or previous credit for MATH 1600 Differential Calculus, or placement in MATH 1700 Integral Calculus or above.

PHYS 1140 Introductory Physics II is the second semester of calculus-based physics with laboratory that covers many applications of modern physics. It is required for all physics, chemistry, and chemical physics majors, and for pre-medical, pre-health, and pre-dental students. This course can satisfy either the Mathematical, Computational and Statistical Reasoning (MCSR) distribution requirement or the Inquiry in the Natural Sciences (INS) distribution requirement. Students with qualifying scores on advanced placement exams can be placed in PHYS 1140 Introductory Physics II without taking the departmental placement exams. All others must take the placement exam. Mathematics prerequisite: concurrent enrollment in or previous credit for MATH 1700 Integral Calculus or MATH 1750 Intermediate Integral Calculus, or placement in MATH 1800 Multivariate Calculus or above.

**PHYS 1033** **(a) ** **The Nature of Time**

What is time, anyway? What do we know about it? How do we understand it? How do we track it? What are the scales and paces of time that apply across different fields of inquiry? In this course students will explore various perspectives on time, aspects of historical and modern time-keeping devices, and applications of time in modern life. Students will develop their writing and research skills through drafts and revisions of various written assignments and receive individualized feedback on their work. The writing assignments will be useful for all subsequent areas of study as they will focus on writing as an opportunity to engage, explore, synthesize, and express information and ideas.
