NEXUS/Physics is an Introductory Physics for Life Sciences (IPLS) class designed to
  • Focus on the development of general scientific competencies such as mathematical modeling and mechanistic reasoning;
  • Fit effectively into a standard curriculum for biologists and pre-health care students;
  • Be biologically authentic – help biology students understand important results they learn in their biology and chemistry classes that rely on physics.



NEXUS/Physics was created by a team based at the University of Maryland as part of the National Experiment in Undergraduate Science Education (NEXUS) funded by the Howard Hughes Medical Institute and the NSF. For more details and a list of contributors, see the "About" tab.

Navigation tips

You can go through the NEXUS/Physics wiki either as a textbook or as a wiki — a collection of connected web pages with readings, examples, exercises, and problems. For details on the structure of the wiki, see the Navigation Tips page.

What's new

Reading materials for this wiki have been uploaded for the first 16 chapters, equivalent to 2 semesters of instruction. They cover topics including a review of basic math, kinematics and dynamics, properties of matter with fluid flow, energy including chemical energy, basic thermodynamics, electric currents, oscillations and waves, and models of light. (See the Chapter list at the left.)

We are continuing to edit existing pages and we’ll be adding pages and examples through the 2019-20 academic year. Please let us know if you have suggestions for pages and examples to be added.

We much value comments, corrections, and suggestions. Send them to If you are commenting on a specific page, please include the page's title in your email.
