tensor algebra

2tensor calculus

tensor the word tensor was introduced

in 1846 by william rowan hamilton. it was

used in its current meaning by woldemar

voigt in 1899. tensor calculus was deve-

loped around 1890 by gregorio ricci-curba-

stro under the title absolute differential

calculus. in the 20th century, the subject

came to be known as tensor analysis, and

achieved broader acceptance with the intro-

duction of einsteins's theory of general

relativity around 1915. tensors are used

also in other fields such as continuum

mechanics.
