Actually, in contradistinction to buzz-wordiness, most of the terms he used such as tensegrity have quite precise definitions- conceptually, as well in mechanical terms. If you want to get a true introduction to the depth and breadth of his thinking, I highly recommend his magnum opus 'Synergetics' [1]. Otherwise, at least take a glance at the meta-structure/heuristics behind his geometrical and design work [2].
