In our department, something is growing up into the darkness. A dark power which seduces my colleagues and their students one by one and leads them into the shadow. Those whose hearts are corrupted by this culture try to prove their research field is the best and deepest field of mathematics, The Lord of the Fields! All around the department, these students and teachers try to disparage the research fields of their colleagues in their discussions and lectures implicitly and explicitly. Analysts against Algebraists, Algebraists against Topologists, pure mathematicians against applied mathematicians and so on. This phenomenon really harms the scientific development of our institute and restricts the possible joint works between researchers in different fields. Also, it prevents students from seeing mathematics as a whole and using the tools of a particular field in another one.
Fortunately there are some researchers in our department who resist this culture. Recently I asked them to participate in an upcoming council to decide on the possible policies which could help us to overcome this situation.
Question. What can we do to overcome the lord of the fields dark culture? How can a teacher teach his/her students to appreciate all fields of mathematics regardless of their beloved research area? How can he/she convince his/her colleagues to stop poisoning their students by this culture?
