related directly to the development of Newtonian physics, and in fact, the

distinction between mathematicians and physicists was not sharply drawn before

the mid-19th century. Until the early 20th century, subjects such as classical

mechanics were often taught in applied mathematics departments at American

universities rather than in physics departments and fluid mechanics may still be

taught in applied mathematics departments. Engineering and computer science

departments have traditionally made use of applied mathematics.
