    This article has one of my favorite concatenations of jargon into a single sentence:

        In this regard, it follows that for any compact regular 2-dimensional manifold with non-zero Euler characteristic, any continuous tangent vector field has at least one zero.
    
    Those are all words most people recognize, but without experience in topology, it is completely incomprehensible.
