The jargon is precise, the translation can provide intuition. You often need both to get the full depth of a concept across. Good academic communication should be a mix of both, with introductions/overviews/conclusions/remarks interspersed along the way to help and conduct the reader, while the precise elements are also given in parallel to explain the technical aspects. Often in presentations the hardest bit is determining the level of precision that is expected by the audience. And usually, the format is intuition first, precise, jargon-heavy details afterwards.
