Historical Perspective
The process of unification might be seen as helping to define what constitutes mathematics as a discipline.
For example, mechanics and mathematical analysis were commonly combined into one subject during the 18th century, united by the differential equation concept; while algebra and geometry were considered largely distinct. Now we consider analysis, algebra, and geometry, but not mechanics, as parts of mathematics because they are primarily deductive formal sciences, while mechanics like physics must proceed from observation. There is no major loss of content, with analytical mechanics in the old sense now expressed in terms of symplectic topology, based on the newer theory of manifolds.

Famous quotes containing the words historical perspective, historical and/or perspective:
“Reason, progress, unselfishness, a wide historical perspective, expansiveness, generosity, enlightened self-interest. I had heard it all my life, and it filled me with despair.”
—Katherine Tait (b. 1923)
“The proverbial notion of historical distance consists in our having lost ninety-five of every hundred original facts, so the remaining ones can be arranged however one likes.”
—Robert Musil (1880–1942)
“Egoism is the law of perspective as it applies to feelings, according to which what is closest to us appears to be large and weighty, while size and weight decrease with our distance from things.”
