1922 H. H. L. A. Brose tr. Weyl Space–Time–Matter i. 58 Tensor analysis tells us how, by differentiating with respect to the space co-ordinates, a new tensor can be derived from the old one in a manner entirely independent of the co-ordinate system. This method, like tensor algebra, is of extreme simplicity.

1939 G. Kron Tensor Anal. Networks p. xvi Tensor analysis may be considered as an extension and generalization of vector analysis from three- to n-dimensional spaces and from Euclidean to non-Euclidean spaces.

1976 Sci. Amer. Aug. 98/2 Einstein's ideas were cast in a language very different from even non-Euclidean geometry, called the absolute differential calculus... Einstein used it and changed its name to tensor analysis.

1977 D. Bagley Enemy xxxiii. 266 This joker is using Hamiltonian quaternions!.. No one..has used Hamiltonian quaternions since 1915 when tensor analysis was invented.
