• Source: Relationship between mathematics and physics

      • The relationship between mathematics and physics has been a subject of study of philosophers, mathematicians and physicists since antiquity, and more recently also by historians and educators. Generally considered a relationship of great intimacy, mathematics has been described as "an essential tool for physics" and physics has been described as "a rich source of inspiration and insight in mathematics".
      In his work Physics, one of the topics treated by Aristotle is about how the study carried out by mathematicians differs from that carried out by physicists. Considerations about mathematics being the language of nature can be found in the ideas of the Pythagoreans: the convictions that "Numbers rule the world" and "All is number", and two millennia later were also expressed by Galileo Galilei: "The book of nature is written in the language of mathematics".


      Historical interplay


      Before giving a mathematical proof for the formula for the volume of a sphere, Archimedes used physical reasoning to discover the solution (imagining the balancing of bodies on a scale). Aristotle classified physics and mathematics as theoretical sciences, in contrast to practical sciences (like ethics or politics) and to productive sciences (like medicine or botany).
      From the seventeenth century, many of the most important advances in mathematics appeared motivated by the study of physics, and this continued in the following centuries (although in the nineteenth century mathematics started to become increasingly independent from physics). The creation and development of calculus were strongly linked to the needs of physics: There was a need for a new mathematical language to deal with the new dynamics that had arisen from the work of scholars such as Galileo Galilei and Isaac Newton. During this period there was little distinction between physics and mathematics; as an example, Newton regarded geometry as a branch of mechanics.
      In the 19th century Auguste Comte in his hierarchy of the sciences, placed physics and astronomy as less general and more complex than mathematics, as both depend on it. In 1900, David Hilbert in his 23 problems for the advancement of mathematical science, considered the axiomatization of physics as his sixth problem. The problem remains open.
      As time progressed, the mathematics used in physics has become increasingly sophisticated, as in the case of superstring theory. Unconventional connections between the two fields are found all the time as in 1975 Wu–Yang dictionary, that related concepts of gauge theory with differential geometry.


      Physics is not math



      Despite the close relationship between math and physics, they are not synonyms. In mathematics objects can be defined exactly and logically related, but the object need have no relationship to experimental measurements. In physics, definitions are abstractions or idealizations, approximations adequate when compared to the natural world. For example, Newton built a physical model around definitions like his second law of motion




      F

      =
      m

      a



      {\displaystyle \mathbf {F} =m\mathbf {a} }

      based on observations, leading to the development of calculus and highly accurate planetary mechanics, but later this definition was superseded by improved models of mechanics. Mathematics deals with entities whose properties can be known with certainty. According to David Hume, only in logic and mathematics statements can be proved (being known with total certainty). While in the physical world one can never know the properties of its beings in an absolute or complete way, leading to a situation that was put by Albert Einstein as "No number of experiments can prove me right; a single experiment can prove me wrong."


      Philosophical problems


      Some of the problems considered in the philosophy of mathematics are the following:

      Explain the effectiveness of mathematics in the study of the physical world: "At this point an enigma presents itself which in all ages has agitated inquiring minds. How can it be that mathematics, being after all a product of human thought which is independent of experience, is so admirably appropriate to the objects of reality?" —Albert Einstein, in Geometry and Experience (1921).
      Clearly delineate mathematics and physics: For some results or discoveries, it is difficult to say to which area they belong: to the mathematics or to physics.
      What is the geometry of physical space?
      What is the origin of the axioms of mathematics?
      How does the already existing mathematics influence in the creation and development of physical theories?
      Is arithmetic analytic or synthetic? (from Kant, see Analytic–synthetic distinction)
      What is essentially different between doing a physical experiment to see the result and making a mathematical calculation to see the result? (from the Turing–Wittgenstein debate)
      Do Gödel's incompleteness theorems imply that physical theories will always be incomplete? (from Stephen Hawking)
      Is mathematics invented or discovered? (millennia-old question, raised among others by Mario Livio)


      Education


      In recent times the two disciplines have most often been taught separately, despite all the interrelations between physics and mathematics. This led some professional mathematicians who were also interested in mathematics education, such as Felix Klein, Richard Courant, Vladimir Arnold and Morris Kline, to strongly advocate teaching mathematics in a way more closely related to the physical sciences.
