## Learning objectives

The course aims to give a basic prerequisite of Physics to other disciplines such as chemistry, biochemistry, physiology, biomechanics, etc.. Additionally, the student should understand the theoretical fundamentals of ever more widespread in basic research and in diagnostic practice as electrophoresis, centrifugation, nuclear magnetic resonance, ultrasound, optical fibers for endoscopic microscopy, laser, X-ray equipment, etc.

## Prerequisites
