Two episodes of Zoom Métiers were screened as part of a school session entitled " What are maths for? " during the 2016 edition of the festival: an opportunity to better understand the application of mathematics in the professional world. These two episodes, each 3 minutes long, introduce us to the professions of Arnaud Woiselle, Image Processing Engineer at Safran SAGEM and Élise Maigné, a research engineer in statistics, econometrics and databases at the Observatory of Rural Development, INRA Toulouse Midi-Pyrénées.
