Requirements (Subjects that are assumed to be known)
Mathematics, Physics and Chemistry (high-school level)
The course consists of two parts. The first one is about the thermodynamics of living systems, i.e., the study of energy transformation in the biological science. The second part introduces some basic physical concepts in Medical Physics, mainly related to the interaction of radiation with matter, atomic and nuclear structure. The following competences and skills should be acquired: - Ability to know and understand the basic laws and concepts of thermodynamics, focusing on its applications to biochemistry and biology - Ability to understand the basic elements of the interaction of radiation with matter, atomic and nuclear structure essential in Medical Physics - Ability to understand and use the mathematics involved in the physical models - Ability to understand and use the scientific method - Ability to understand and use the scientific language - Ability to develop skills to solve problems - Ability to use scientific instruments and analyze experimental data - Ability to retrieve and analyse information from different sources - Ability to work in a team.

Learning activities and methodology
* Lectures where the theoretical concepts are explained The lecturer will provide a file with the following information (1 week in advance): - Main topics to be discussed during the session - Chapters/sections in each of the text books provided in the bibliography where the student can read about these topics * Activities in groups (2-3 people) to solve problems: The main skills to be acquired in these activities are: - To understand the statement of a problem (for instance drawing an scheme that summarizes the statement) - To identify the physical phenomenon involved in the statement and the physical laws involved - To develop an strategy to reach the objective (for instance breaking the problem in small subproblems) - To be careful in the use of mathematics - To be able to make a critical analysis of the results (is the final number sensible?, are the dimensions consistent?) * Small tasks focused to search for scientific information from different sources (mainly internet) * Laboratoy sessions (~24 students divided in 2 people groups) The main skills to be developed in this activity are: - To understand that physics is an experimental science and they can reproduce the laws that have been theoretically explained in the lectures - To use scientific instruments and to be careful in its operation - To be careful in the acquisiton of experimental data - To learn the basis for the management of a scientific data set - To be able to write a report with the main results of the experiment - To be able to discuss in a critical way the experimental results: have we achieved the goals of the experiment?
