Slavik Tabakov, Co-Editor, King’s College London, UK EDITORIAL 2 principles in order to make intelligent decisions that will contribute to effective and safe use. Medical physicists have the opportunity to provide this education. The challenge is that the physics knowledge needed by physicians for effective clinical applications is often different from what we as medical physicists learned in our academic studies. The common practice of “teaching” what “we were taught” is generally not appropriate. Let’s consider the guidance provided by Albert Einstein shown here. What does that mean for us as clinical medical physicists and medical physics educators? Especially for our students who are physicians and other clinical professionals we need to develop conditions and learning activities in which they integrate physics directly into the clinical practice. This is achieved through a close collaboration between physicists With the rapid advances in both medical imaging and and physicians where knowledge is shared in both directions. radiation therapy technology and applications around the One of the goals of this journal is to publish articles that can contribute to more clinically- focused physics education world, the role of the medical physicist as an educator is expanding and becoming much more significant, but also and provide resources, and links to web-based resources, for medical physicists to use. with some challenges.
