Hans-Uwe Otto,Thomas Rauschenbach nor is it possible to decide by deductive reasoning what form the product of two vectors should take. Since vectors have their origin in physical problems, definitions for the products of vectors must be devised that will be consistent with the way in which such products occur in applications to physical science.

Wilhelm Hofmann,Renate Martinsent value. These surfaces divide up the region of space into a series of layers or laminae. Associated therewith is a vector field . directed everywhere normal to the level surfaces, i.e. in the direction of the greatest rate of increase of . at any point and having a magnitude equal to that rate of increase. This is expressed by 4.3, namely,
