Let there be light: Understanding physics - Grasping physics. Whether it's basic knowledge of physics or in-depth explanations that are needed, the new "Haas" optimally prepares the topics. Clearly structured, the theory from mechanics to optics to radioactivity is made easy to understand. How bees utilize the polarization of light and many other illustrative examples from nature and practice make the theory tangible. Exercises with solutions for each chapter promote comprehension-oriented learning and success monitoring. Based on the catalog of subjects, the "Haas" remains the standard work for pharmacy and medical students as well as for all students taking physics as a minor.
