Our work consists of formalising. It is sometimes difficult to get oneself accepted since, even if there are needs for formal mathematics (see Mathematics in the real world), these are not always priorities for the applied sciences. But our analyses are essential since they can be used to ensure that a model is exploited to its greatest potential or, on the contrary, to invalidate methods that intuitively appear correct. This does not always please everyone since it upsets customs and priorities. But basically all we want to do is to simply improve our understanding of phenomena.
Distrust and lack of confidence are also due to distance and the limited contact with other communities. It is the physicists, considered more likely to understand the vocabulary of other scientists, who are generally called on to create models. However, associating mathematicians from the outset in the construction of models would enable more innovative results to be obtained (See Mathematics and the Earth: a long story).
