When he returns to the classroom, his experience in such a large and advanced laboratory will enable him to demonstrate to his pupils how important physics, mathematics and information technology are to the ‘real world’. In his work at ELSA, mathematics is useful for modelling particular phenomena or analysing data. Physics is useful for properly conducting the experiments, for developing new protection devices and for judging the results of the simulations and data analysis. Finally, informatics is the tool used in all aspects of his research work. In short, he plans to use his experience to motivate his students.
