I will make an excursion through irreducibility criteria of polynomials in one variable with coefficients in a field. The purpose of the talk is to convince the audience that if one takes the words « size » and « coefficients » in a sufficiently extended sense, the answer to this question is in the end positive, however absurd it seems to be at first glance. The talk will be self-contained, and the key notions of valuation and Newton polygon will be introduced.
