ASTR 497 - MOND - Spring 2023
Course Description
This course introduces and explores the Modified Newtonian Dynamics (MOND) hypothesized
by Moti Milgrom as an explanation for observed acceleration discrepancies that are
conventionally attributed to dark matter.
Learning Outcomes
Students will become familiar with MOND as a theory: its basic tenets, its applications,
and possible extentions to relativistic theory. They will explore tests of the theory:
its scope and limitations, its successes and failures as a predictive theory,
and context in relation to the conventional dark matter picture. By the end of the course,
students will be able to explain MOND to a peer, recognize situations in which it applies,
and apply it to the dynamics of low-acceleration systems.
Course Work & Grades
This is primarilly a reading and discussion course.
It is offered for a maximum of 2 credits on a pass/no pass basis.
A passing grade will be obtained by consistent attendance with participation in group
discussions, in-class exercises, assigned readings, and other activities as assigned.
