<p>The area of study known as the <b>history of mathematics</b> is primarily an investigation into the origin of discoveries in <a href="/wiki/Mathematics" title="Mathematics">mathematics</a> and, to a lesser extent, an investigation into the <a href="/wiki/History_of_mathematical_notation" title="History of mathematical notation">mathematical methods and notation of the past</a>.</p>
|
||||
<p>Before the <a href="/wiki/Modern_age" title="Modern age" class="mw-redirect">modern age</a> and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales. The most ancient mathematical texts available are <i><a href="/wiki/Plimpton_322" title="Plimpton 322">Plimpton 322</a></i> (<a href="/wiki/Babylonian_mathematics" title="Babylonian mathematics">Babylonian mathematics</a> c. 1900 BC),<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span>[</span>2<span>]</span></a></sup> the <i><a href="/wiki/Rhind_Mathematical_Papyrus" title="Rhind Mathematical Papyrus">Rhind Mathematical Papyrus</a></i> (Egyptian mathematics c. 2000-1800 BC)<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span>[</span>3<span>]</span></a></sup> and the <i><a href="/wiki/Moscow_Mathematical_Papyrus" title="Moscow Mathematical Papyrus">Moscow Mathematical Papyrus</a></i> (<a href="/wiki/Egyptian_mathematics" title="Egyptian mathematics" class="mw-redirect">Egyptian mathematics</a> c. 1890 BC). All of these texts concern the so-called <a href="/wiki/Pythagorean_theorem" title="Pythagorean theorem">Pythagorean theorem</a>, which seems to be the most ancient and widespread mathematical development after basic arithmetic and geometry.</p>
|
||||
<p>The study of mathematics as a subject in its own right begins in the 6th century BC with the <a href="/wiki/Pythagoreans" title="Pythagoreans" class="mw-redirect">Pythagoreans</a>, who coined the term "mathematics" from the ancient Greek <i>μάθημα</i> (<i>mathema</i>), meaning "subject of instruction".<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span>[</span>4<span>]</span></a></sup> <a href="/wiki/Greek_mathematics" title="Greek mathematics">Greek mathematics</a> greatly refined the methods (especially through the introduction of deductive reasoning and <a href="/wiki/Mathematical_rigor" title="Mathematical rigor" class="mw-redirect">mathematical rigor</a> in <a href="/wiki/Mathematical_proof" title="Mathematical proof">proofs</a>) and expanded the subject matter of mathematics.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span>[</span>5<span>]</span></a></sup> <a href="/wiki/Counting_rods" title="Counting rods">Chinese mathematics</a> made early contributions, including a <a href="/wiki/Place_value_system" title="Place value system" class="mw-redirect">place value system</a>.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span>[</span>6<span>]</span></a></sup><sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span>[</span>7<span>]</span></a></sup> The <a href="/wiki/Hindu-Arabic_numeral_system" title="Hindu-Arabic numeral system" class="mw-redirect">Hindu-Arabic numeral system</a> and the rules for the use of its operations, in use throughout the world today, likely evolved over the course of the first millennium AD in <a href="/wiki/Indian_mathematics" title="Indian mathematics">India</a> and were transmitted to the west via Islamic mathematics through the work of <a href="/wiki/Mu%E1%B8%A5ammad_ibn_M%C5%ABs%C4%81_al-Khw%C4%81rizm%C4%AB" title="Muḥammad ibn Mūsā al-Khwārizmī">Muḥammad ibn Mūsā al-Khwārizmī</a>.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span>[</span>8<span>]</span></a></sup><sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span>[</span>9<span>]</span></a></sup> <a href="/wiki/Islamic_mathematics" title="Islamic mathematics" class="mw-redirect">Islamic mathematics</a>, in turn, developed and expanded the mathematics known to these civilizations.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span>[</span>10<span>]</span></a></sup> Many Greek and Arabic texts on mathematics were then <a href="/wiki/Latin_translations_of_the_12th_century" title="Latin translations of the 12th century">translated into Latin</a>, which led to further development of mathematics in <a href="/wiki/Middle_Ages" title="Middle Ages">medieval Europe</a>.</p>
|

<p>From ancient times through the <a href="/wiki/Postclassical_age" title="Postclassical age" class="mw-redirect">Middle Ages</a>, bursts of mathematical creativity were often followed by centuries of stagnation. Beginning in <a href="/wiki/Renaissance" title="Renaissance">Renaissance</a> <a href="/wiki/Italy" title="Italy">Italy</a> in the 16th century, new mathematical developments, interacting with new scientific discoveries, were made at an <a href="/wiki/Exponential_growth" title="Exponential growth">increasing pace</a> that continues through the present day.</p>

<p><a href="/wiki/Babylonia" title="Babylonia">Babylonian</a> mathematics refers to any mathematics of the people of <a href="/wiki/Mesopotamia" title="Mesopotamia">Mesopotamia</a> (modern <a href="/wiki/Iraq" title="Iraq">Iraq</a>) from the days of the early <a href="/wiki/Sumer" title="Sumer">Sumerians</a> through the <a href="/wiki/Hellenistic_period" title="Hellenistic period">Hellenistic period</a> almost to the dawn of <a href="/wiki/Christianity" title="Christianity">Christianity</a>.<sup id="cite_ref-20" class="reference"><a href="#cite_note-20"><span>[</span>20<span>]</span></a></sup> It is named Babylonian mathematics due to the central role of <a href="/wiki/Babylon" title="Babylon">Babylon</a> as a place of study. Later under the <a href="/wiki/Caliphate" title="Caliphate">Arab Empire</a>, Mesopotamia, especially <a href="/wiki/Baghdad" title="Baghdad">Baghdad</a>, once again became an important center of study for <a href="/wiki/Islamic_mathematics" title="Islamic mathematics" class="mw-redirect">Islamic mathematics</a>.</p>
|
||||
<p>In contrast to the sparsity of sources in <a href="/wiki/Egyptian_mathematics" title="Egyptian mathematics" class="mw-redirect">Egyptian mathematics</a>, our knowledge of Babylonian mathematics is derived from more than 400 clay tablets unearthed since the 1850s.<sup id="cite_ref-21" class="reference"><a href="#cite_note-21"><span>[</span>21<span>]</span></a></sup> Written in <a href="/wiki/Cuneiform_script" title="Cuneiform script" class="mw-redirect">Cuneiform script</a>, tablets were inscribed whilst the clay was moist, and baked hard in an oven or by the heat of the sun. Some of these appear to be graded homework.</p>
|
||||
<p>The earliest evidence of written mathematics dates back to the ancient <a href="/wiki/Sumer" title="Sumer">Sumerians</a>, who built the earliest civilization in Mesopotamia. They developed a complex system of <a href="/wiki/Metrology" title="Metrology">metrology</a> from 3000 BC. From around 2500 BC onwards, the Sumerians wrote <a href="/wiki/Multiplication_table" title="Multiplication table">multiplication tables</a> on clay tablets and dealt with <a href="/wiki/Geometry" title="Geometry">geometrical</a> exercises and <a href="/wiki/Division_(mathematics)" title="Division (mathematics)">division</a> problems. The earliest traces of the Babylonian numerals also date back to this period.<sup id="cite_ref-22" class="reference"><a href="#cite_note-22"><span>[</span>22<span>]</span></a></sup></p>
|
||||
<p>The majority of recovered clay tablets date from 1800 to 1600 BC, and cover topics which include fractions, algebra, quadratic and cubic equations, and the calculation of <a href="/wiki/Regular_number" title="Regular number">regular</a> <a href="/wiki/Multiplicative_inverse" title="Multiplicative inverse">reciprocal</a> <a href="/wiki/Twin_prime" title="Twin prime">pairs</a>.<sup id="cite_ref-23" class="reference"><a href="#cite_note-23"><span>[</span>23<span>]</span></a></sup> The tablets also include multiplication tables and methods for solving <a href="/wiki/Linear_equation" title="Linear equation">linear</a> and <a href="/wiki/Quadratic_equation" title="Quadratic equation">quadratic equations</a>. The Babylonian tablet YBC 7289 gives an approximation of √2 accurate to five decimal places.</p>
|
||||
<p>Babylonian mathematics were written using a <a href="/wiki/Sexagesimal" title="Sexagesimal">sexagesimal</a> (base-60) <a href="/wiki/Numeral_system" title="Numeral system">numeral system</a>. From this derives the modern day usage of 60 seconds in a minute, 60 minutes in an hour, and 360 (60 x 6) degrees in a circle, as well as the use of seconds and minutes of arc to denote fractions of a degree. Babylonian advances in mathematics were facilitated by the fact that 60 has many divisors. Also, unlike the Egyptians, Greeks, and Romans, the Babylonians had a true place-value system, where digits written in the left column represented larger values, much as in the <a href="/wiki/Decimal" title="Decimal">decimal</a> system. They lacked, however, an equivalent of the decimal point, and so the place value of a symbol often had to be inferred from the context. On the other hand, this "defect" is equivalent to the modern-day usage of floating point arithmetic; moreover, the use of base 60 means that any reciprocal of an integer which is a multiple of divisors of 60 necessarily has a finite expansion to the base 60. (In decimal arithmetic, only reciprocals of multiples of 2 and 5 have finite decimal expansions.) Accordingly, there is a strong argument that arithmetic Old Babylonian style is considerably more sophisticated than that of current usage.</p>
|
||||
<p>The interpretation of Plimpton 322 was the source of controversy for many years after its significance in the context of Pythagorean triangles was realized. In historical context, inheritance problems involving equal-area subdivision of triangular and trapezoidal fields (with integer length sides) quickly convert into the need to calculate the <a href="/wiki/Square_root_of_2" title="Square root of 2">square root of 2</a>, or to solve the "Pythagorean equation" in integers.</p>
|
||||
<p>Rather than considering a square as the sum of two squares, we can equivalently consider a square as a difference of two squares. Let a, b and c be integers that form a Pythagorean Triple: a^2 + b^2 = c^2. Then c^2 - a^2 = b^2, and using the expansion for the difference of two squares we get (c-a)(c+a)= b^2. Dividing by b^2, it becomes the product of two rational numbers giving 1: (c/b - a/b)(c/b + a/b) = 1. We require two rational numbers which are reciprocals and which differ by 2(a/b). This is easily solved by consulting a table of reciprocal pairs. E.g., (1/2) (2) = 1 is a pair of reciprocals which differ by 3/2 = 2(a/b) Thus a/b = 3/4, giving a=3, b=4 and so c=5.</p>
|
||||
<p>Solutions of the original equation are thus constructed by choosing a rational number x, from which Pythagorean-triples are 2x, x^2-1, x^2+1. Other triples are made by scaling these by an integer (the scaling integer being half the difference between the largest and one other side). All Pythagorean triples arise in this way, and the examples provided in Plimpton 322 involve some quite large numbers, by modern standards, such as (4601, 4800, 6649) in decimal notation.</p>

<p>Greek mathematics was much more sophisticated than the mathematics that had been developed by earlier cultures. All surviving records of pre-Greek mathematics show the use of inductive reasoning, that is, repeated observations used to establish rules of thumb. Greek mathematicians, by contrast, used deductive reasoning. The Greeks used logic to derive conclusions from definitions and axioms, and used <a href="/wiki/Mathematical_rigor" title="Mathematical rigor" class="mw-redirect">mathematical rigor</a> to <a href="/wiki/Mathematical_proof" title="Mathematical proof">prove</a> them.<sup id="cite_ref-33" class="reference"><a href="#cite_note-33"><span>[</span>33<span>]</span></a></sup></p>

<p>Early Chinese mathematics is so different from that of other parts of the world that it is reasonable to assume independent development.<sup id="cite_ref-73" class="reference"><a href="#cite_note-73"><span>[</span>73<span>]</span></a></sup> The oldest extant mathematical text from China is the <i><a href="/wiki/Zhou_Bi_Suan_Jing" title="Zhou Bi Suan Jing">Chou Pei Suan Ching</a></i>, variously dated to between 1200 BC and 100 BC, though a date of about 300 BC appears reasonable.<sup id="cite_ref-Boyer_1991_loc.3DChina_and_India_p._196_74-0" class="reference"><a href="#cite_note-Boyer_1991_loc.3DChina_and_India_p._196-74"><span>[</span>74<span>]</span></a></sup></p>

<p>Of particular note is the use in Chinese mathematics of a decimal positional notation system, the so-called "rod numerals" in which distinct ciphers were used for numbers between 1 and 10, and additional ciphers for powers of ten.<sup id="cite_ref-75" class="reference"><a href="#cite_note-75"><span>[</span>75<span>]</span></a></sup> Thus, the number 123 would be written using the symbol for "1", followed by the symbol for "100", then the symbol for "2" followed by the symbol for "10", followed by the symbol for "3". This was the most advanced number system in the world at the time, apparently in use several centuries before the common era and well before the development of the Indian numeral system.<sup id="cite_ref-76" class="reference"><a href="#cite_note-76"><span>[</span>76<span>]</span></a></sup> Rod numerals allowed the representation of numbers as large as desired and allowed calculations to be carried out on the <i><a href="/wiki/Suanpan" title="Suanpan">suan pan</a></i>, or Chinese abacus. The date of the invention of the <i>suan pan</i> is not certain, but the earliest written mention dates from AD 190, in Xu Yue's <i>Supplementary Notes on the Art of Figures</i>.</p>

<p>In 212 BC, the Emperor <a href="/wiki/Qin_Shi_Huang" title="Qin Shi Huang">Qin Shi Huang</a> (Shi Huang-ti) commanded all books in the Qin Empire other than officially sanctioned ones be burned.

<p>During the Renaissance the desire of artists to represent the natural world realistically, together with the rediscovered philosophy of the Greeks, led artists to study mathematics. They were also the engineers and architects of that time, and so had need of mathematics in any case.

<p>In a 1900 speech to the <a href="/wiki/International_Congress_of_Mathematicians" title="International Congress of Mathematicians">International Congress of Mathematicians</a>, <a href="/wiki/David_Hilbert" title="David Hilbert">David Hilbert</a> set out a list of <a href="/wiki/Hilbert%27s_problems" title="Hilbert's problems">23 unsolved problems in mathematics</a>. These problems, spanning many areas of mathematics, formed a central focus for much of 20th-century mathematics. Today, 10 have been solved, 7 are partially solved, and 2 are still open. The remaining 4 are too loosely formulated to be stated as solved or not.</p>

<p>Notable historical conjectures were finally proven. In 1976, <a href="/wiki/Wolfgang_Haken" title="Wolfgang Haken">Wolfgang Haken</a> and <a href="/wiki/Kenneth_Appel" title="Kenneth Appel">Kenneth Appel</a> used a computer to prove the <a href="/wiki/Four_color_theorem" title="Four color theorem">four color theorem</a>. <a href="/wiki/Andrew_Wiles" title="Andrew Wiles">Andrew Wiles</a>, building on the work of others, proved <a href="/wiki/Fermat%27s_Last_Theorem" title="Fermat's Last Theorem">Fermat's Last Theorem</a> in 1995. <a href="/wiki/Paul_Cohen_(mathematician)" title="Paul Cohen (mathematician)">Paul Cohen</a> and <a href="/wiki/Kurt_G%C3%B6del" title="Kurt Gödel">Kurt Gödel</a> proved that the <a href="/wiki/Continuum_hypothesis" title="Continuum hypothesis">continuum hypothesis</a> is <a href="/wiki/Logical_independence" title="Logical independence" class="mw-redirect">independent</a> of (could neither be proved nor disproved from) the <a href="/wiki/ZFC" title="ZFC" class="mw-redirect">standard axioms of set theory</a>.

<p>Mathematical collaborations of unprecedented size and scope took place. An example is the <a href="/wiki/Classification_of_finite_simple_groups" title="Classification of finite simple groups">classification of finite simple groups</a> (also called the "enormous theorem"), whose proof between 1955 and 1983 required 500-odd journal articles by about 100 authors, and filling tens of thousands of pages. A group of French mathematicians, including <a href="/wiki/Jean_Dieudonn%C3%A9" title="Jean Dieudonné">Jean Dieudonné</a> and <a href="/wiki/Andr%C3%A9_Weil" title="André Weil">André Weil</a>, publishing under the <a href="/wiki/Pseudonym" title="Pseudonym">pseudonym</a> "<a href="/wiki/Nicolas_Bourbaki" title="Nicolas Bourbaki">Nicolas Bourbaki</a>", attempted to exposit all of known mathematics as a coherent rigorous whole.

<p>The development and continual improvement of <a href="/wiki/Computer" title="Computer">computers</a>, at first mechanical analog machines and then digital electronic machines, allowed <a href="/wiki/Industry" title="Industry">industry</a> to deal with larger and larger amounts of data to facilitate mass production and distribution and communication, and new areas of mathematics were developed to deal with this: <a href="/wiki/Alan_Turing" title="Alan Turing">Alan Turing</a>'s <a href="/wiki/Computability_theory" title="Computability theory">computability theory</a>; <a href="/wiki/Computational_complexity_theory" title="Computational complexity theory">complexity theory</a>; <a href="/wiki/Derrick_Henry_Lehmer" title="Derrick Henry Lehmer">Derrick Henry Lehmer</a>'s use of <a href="/wiki/ENIAC" title="ENIAC">ENIAC</a> to further number theory and the <a href="/wiki/Lucas-Lehmer_test" title="Lucas-Lehmer test" class="mw-redirect">Lucas-Lehmer test</a>; <a href="/wiki/Claude_Shannon" title="Claude Shannon">Claude Shannon</a>'s <a href="/wiki/Information_theory" title="Information theory">information theory</a>; <a href="/wiki/Signal_processing" title="Signal processing">signal processing</a>; <a href="/wiki/Data_analysis" title="Data analysis">data analysis</a>; <a href="/wiki/Mathematical_optimization" title="Mathematical optimization">optimization</a> and other areas of <a href="/wiki/Operations_research" title="Operations research">operations research</a>. In the preceding centuries much mathematical focus was on <a href="/wiki/Calculus" title="Calculus">calculus</a> and continuous functions, but the rise of computing and communication networks led to an increasing importance of <a href="/wiki/Discrete_mathematics" title="Discrete mathematics">discrete</a> concepts and the expansion of <a href="/wiki/Combinatorics" title="Combinatorics">combinatorics</a> including <a href="/wiki/Graph_theory" title="Graph theory">graph theory</a>. The speed and data processing abilities of computers also enabled the handling of mathematical problems that were too time-consuming to deal with by pencil and paper calculations, leading to areas such as <a href="/wiki/Numerical_analysis" title="Numerical analysis">numerical analysis</a> and <a href="/wiki/Symbolic_computation" title="Symbolic computation">symbolic computation</a>.

<p>At the same time, deep insights were made about the limitations to mathematics. In 1929 and 1930, it was proved the truth or falsity of all statements formulated about the <a href="/wiki/Natural_number" title="Natural number">natural numbers</a> plus one of addition and multiplication, was <a href="/wiki/Decidability_(logic)" title="Decidability (logic)">decidable</a>, i.e. could be determined by some algorithm. In 1931, <a href="/wiki/Kurt_G%C3%B6del" title="Kurt Gödel">Kurt Gödel</a> found that this was not the case for the natural numbers plus both addition and multiplication; this system, known as <a href="/wiki/Peano_arithmetic" title="Peano arithmetic" class="mw-redirect">Peano arithmetic</a>, was in fact <a href="/wiki/Incompleteness_theorem" title="Incompleteness theorem" class="mw-redirect">incompletable</a>. (Peano arithmetic is adequate for a good deal of <a href="/wiki/Number_theory" title="Number theory">number theory</a>, including the notion of <a href="/wiki/Prime_number" title="Prime number">prime number</a>.) A consequence of Gödel's two <a href="/wiki/Incompleteness_theorem" title="Incompleteness theorem" class="mw-redirect">incompleteness theorems</a> is that in any mathematical system that includes Peano arithmetic (including all of <a href="/wiki/Mathematical_analysis" title="Mathematical analysis">analysis</a> and <a href="/wiki/Geometry" title="Geometry">geometry</a>), truth necessarily outruns proof, i.e. there are true statements that <a href="/wiki/Incompleteness_theorem" title="Incompleteness theorem" class="mw-redirect">cannot be proved</a> within the system. Hence mathematics cannot be reduced to mathematical logic, and <a href="/wiki/David_Hilbert" title="David Hilbert">David Hilbert</a>'s dream of making all of mathematics complete and consistent needed to be reformulated.</p>

The points of resemblance, particularly between early European calculus and the Keralese work on power series, have even inspired suggestions of a possible transmission of mathematical ideas from the Malabar coast in or after the 15th century to the Latin scholarly world (e.g., in (Bag 1979, 285)). ... It should be borne in mind, however, that such an emphasis on the similarity of Sanskrit (or Malayalam) and Latin mathematics risks diminishing our ability fully to see and comprehend the former. To speak of the Indian “discovery of the principle of the differential calculus” somewhat obscures the fact that Indian techniques for expressing changes in the Sine by means of the Cosine or vice versa, as in the examples we have seen, remained within that specific trigonometric context. The differential “principle” was not generalized to arbitrary functions—in fact, the explicit notion of an arbitrary function, not to mention that of its derivative or an algorithm for taking the derivative, is irrelevant here"</span></li>

When this was first described in English by Charles Whish, in the 1830s, it was heralded as the Indians' discovery of the calculus. This claim and Mādhava's achievements were ignored by Western historians, presumably at first because they could not admit that an Indian discovered the calculus, but later because no one read anymore the <i>Transactions of the Royal Asiatic Society</i>, in which Whish's article was published. The matter resurfaced in the 1950s, and now we have the Sanskrit texts properly edited, and we understand the clever way that Mādhava derived the series <i>without</i> the calculus; but many historians still find it impossible to conceive of the problem and its solution in terms of anything other than the calculus and proclaim that the calculus is what Mādhava found. In this case the elegance and brilliance of Mādhava's mathematics are being distorted as they are buried under the current mathematical solution to a problem to which he discovered an alternate and powerful solution."</span></li>

Islamic scholars nearly developed a general formula for finding integrals of polynomials by A.D. 1000—and evidently could find such a formula for any polynomial in which they were interested. But, it appears, they were not interested in any polynomial of degree higher than four, at least in any of the material that has come down to us. Indian scholars, on the other hand, were by 1600 able to use ibn al-Haytham's sum formula for arbitrary integral powers in calculating power series for the functions in which they were interested. By the same time, they also knew how to calculate the differentials of these functions. So some of the basic ideas of calculus were known in Egypt and India many centuries before Newton. It does not appear, however, that either Islamic or Indian mathematicians saw the necessity of connecting some of the disparate ideas that we include under the name calculus. They were apparently only interested in specific cases in which these ideas were needed. ... There is no danger, therefore, that we will have to rewrite the history texts to remove the statement that Newton and Leibniz invented calculus. They were certainly the ones who were able to combine many differing ideas under the two unifying themes of the derivative and the integral, show the connection between them, and turn the calculus into the great problem-solving tool we have today."</span></li>
