A Guide to Selecting the Best Introductory Physics Courses for You

The Yale Physics Department offers four two-semester introductory physics sequences, namely PHYS 1700/1710, PHYS 1800/18100, PHYS 2000/2010, and PHYS 2600/2610, any of which can be used towards an undergraduate degree in Physics. It is not always easy for students to identify the most appropriate physics sequence for them, and so the following is a guide to aid students and their advisors in the decision-making process.  Whichever sequence you pick, you must take it in order, i.e. PHYS 1700 before PHYS 1710, PHYS 1800 before PHYS 18100, PHYS 2000 before PHYS 2010 and PHYS 2600 before PHYS 2610. We strongly recommend too that you stick in the same sequence throughout the entire year.

PHYS 1700-1710 is a novel introductory physics sequence aimed at students interested in the biological sciences and medicine.  In addition to fundamental principles and applications of Newtonian mechanics, PHYS 1700 includes quantitative treatments of random walks, Brownian motion and diffusion, disease progression, drug delivery, fluid mechanics of the circulatory system, and statistical mechanical treatments of a number of cellular processes. The goals of PHYS 1700 are: (1) Demonstrate the application of physics and mathematics to the life sciences and the human body via highly-relevant examples; (2) Introduce biological science majors and future clinicians to a set of mathematical and physical principles and techniques that will enable a deeper scientific understanding of biological systems, including the human body; (3) Seed an appreciation of the power of mathematical and physical approaches in biology and medicine; (4) Satisfy the physics requirements of biological science majors at Yale, and satisfy the physics requirement for medical school. Although PHYS 1700 is designed to appeal to future clinicians, it is not an MCAT preparation course, although it does address some of the competencies specified in MCAT 20105. PHYS 1700 is suitable for students with little or no physics background. However, it is recommended that students who chose to take PHYS 1700 should have previously taken Yale’s introductory chemistry and biology sequences, or equivalent AP courses. PHYS 1700-1710 is a calculus-based sequence, and knowledge of differential and integral calculus at the level of MATH 1120 or equivalent is a prerequisite. Although not a prerequisite, having previously taken MATH 1160 will facilitate PHYS 1700. PHYS 1700 is a prerequisite for PHYS 1710, which covers harmonic oscillators, waves, electromagnetism, Maxwell’s equations, optics, quantum mechanics, and cellular feedback. Please don’t let the course numbering fool you; PHYS 1700-1710 is not a less challenging sequence than PHYS 1800-18100.

PHYS 1800-18100 follows a traditional introductory physics syllabus and is the sequence that most resembles a typical high school or AP physics course in content. The goal of PHYS 1800-18100 is to provide a strong foundation in physics that will satisfy the physics requirements of other science and engineering majors at Yale, and for medical school, and to provide students the experience of thinking like a physicist. PHYS 1800 includes: Newtonian mechanics, planetary motion, rigid body rotation, harmonic oscillators, and waves. Calculus at the level of MATH 1150 or equivalent is a prerequisite for PHYS 1800. PHYS 1800 is suitable for students with little or no physics background, but, of course, it will be less challenging for those who have previously taken high school or AP physics. PHYS 18100 provides a comprehensive first course in electricity and magnetism. Taking MATH 1200 previously or concurrently is recommended for PHYS 18100. However if you cannot take MATH 1200 please talk to the PHYS 18100 instructor before deciding not to take PHYS 18100. In deciding between PHYS 1700/1710 and PHYS 1800/18100, personal preference should guide you to the right course for your learning style and interests.

PHYS 2000-2010 is a more advanced version of a traditional introductory physics syllabus, aimed at students with a strong interest in physics. The sequence will be challenging for a student who has not previously taken a physics course; there will be a less thorough review of basic high school physics and more new material will be introduced. Conversely, the well-prepared student might be bored (and thus dissatisfied) with PHYS 1800 and is encouraged to take PHYS 2000. One goal of PHYS 2000-2010 is to bring in as much modern physics (relativity, quantum mechanics, etc.) as is possible, while still covering the basic syllabus of the typical introductory sequence. Differential and integral calculus is used extensively in PHYS 2000 and multivariable calculus  in PHYS 2010. MATH 1200 or ENAS 1510 must be taken previously or concurrently with PHYS 2010.

PHYS 2600-2610 ‘Intensive Introductory Physics,’ is an advanced course aimed at students with a strong physics and mathematics background, who have typically already completed a yearlong calculus-based AP Physics course in mechanics and electricity and magnetism. The sequence will emphasize a more sophisticated treatment of mechanics, special relativity, electricity and magnetism before focusing on quantum mechanics.   Rather than giving the usual historical development of quantum mechanics, the course takes a modern approach by discussing quantum information, measurements and computation.  Students will learn enough of the basics to be able to program and operate publicly-accessible cloud-based quantum computers.  One of MATH 1200 or ENAS 1510 or an equivalent course in multivariable calculus is a co-requisite or prerequisite for PHYS 2600/2610.  A course in linear algebra is very useful for the quantum mechanics portion of PHYS 2610, and is recommended but not a co-requisite. Since a strong foundation in physics is important, PHYS 2600-2610 should not be taken by a student who has not seen both mechanics and electricity & magnetism at the typical college/AP level.  Conversely, the very well-prepared student might be bored (and thus dissatisfied) with PHYS 2000 and should be encouraged to take PHYS 2600.
