AnnouncementsThe American Journal of Physics (AJP) invites you to submit papers for a special theme issue focused on The Intersection of Biology and Physics.
The field of biological physics and the physics education of biology and other health-science students have experienced tremendous growth in recent years. New findings, applications, and technologies in biological and medical physics are having far reaching consequences that affect and influence the science community, the education of future scientists and health-care workers, and the general population. As a result, leaders in Physics Education Research have begun to focus their attention on the specific needs of students in the biological sciences, the different ways physicists and biologists view the nature of science, and the interactions of scientists in these disciplines.
