The first records of mathematical activity date back to early Egypt and Mesopotamia also India and China. But maths underwent a major transition in ancient Greece where proofs were first demonstrated and geometry took precedence over arithmetic. During the European Dark Age further mathematical progress was made by Arab mathematicians during an Islamic Golden Age when translations of Greeks mathematics became available. Only with the Renaissance was there a revival of mathematics in Europe that culminated in the 17th century as a Heroic Age of mathematics. Being a symbolic ‘language’ mathematics has always involved the development of the most efficient systems of notation.

Mesopotamia, Egypt, India, and China

Evidence for mathematical principles and procedures appear in the early civilizations of Mesopotamia, Egypt, the Indus Valley and China. All had arithmetic and geometry, the Egyptians and Babylonians using fractions by about 2000 BCE. China had decimal fractions about 1500 years before Europe. Babylonians were aware of Pythagoras’s theorem before Pythagoras while Babylonians used a sexagesimal (base 60) for numbers and fractions which persisted into the 17th century CE. Indo-Arabic numerals began in India around 3rd century BCE. But none used formal proofs or demonstrations of logical underpinnings. Related to commerce, surveying and building but also recreational puzzles.

Ancient Greece

Deductive proofs began with the ancient Greeks, the first attributed to Thales of Miletus beginning with agreed axioms and definitions connected by logic. Greeks worked mostly with geometry with little number theory and a little trigonometry as an extension of geometry used in astronomy – even how the Earth moved round the Sun. This was done by Euclid (4th BCE) studied by all subsequent major mathematicians and the Pythagoreans (6th BCE) who discovered irrational numbers. Archimedes (3rd BCE) excelled at geometry and number theory and the preliminary ideas relating to future calculus as one of the greatest mathematicians of all time. Appolonius (2nd BCE) carried out foundational studies in conic sections (ellipse, parabola etc.) so important later in astronomy.

Islamic Golden Age

400-1200 CE was a European Dark Age with mathematical work being done by Islamic scholars after the establishment of Islam by Mohammed in the 7th century CE building on ancient texts and used Hindu/Arabic (Indian) numerals and decimal fractions c. 800-1200 CE. The word ‘Algebra’ is derived from the Arabic ‘Al-Jabr’ in geometric form c. 825 cubic equations by Omar Khayam who was not surpassed in Europe until 16th century.

European Renaissance & Scientific Revolution

Around 1000 CE Hindu/Arabic numerals are first used in Europe, the Fibonnacci series produced the Liber Abaci in 1200s ittook300years to get these numerals accepted. In 1450 universities could cope with addition and subtraction but multiplication and division was only available in Italy (Europeans were still using cumbersome Roman numerals).

Only in 1585 did Belgian Simon Stevin advocate base 10 (decimal) fractions although his notation was clumsy and ignored until the 1620s. Scotsman John Napier invented logarithms in 1614 noting that you could convert multiplication into addition (products to sums), quotients into differences etc. but his base was clumsy so Briggs in 1624 developed base 10 logs. Today’s symbolic algebra (that of today) was launched in Europe in 16th century, moving from rhetorical to syncopated algebra as mathematics in general was gathering momentum. Geometry and algebra now become united with the modern-day coordinate system established by Frenchman Fermat and Descartes (method) in the 1630s. Could find the solutions to algebraic equations by graphing them.

The 17th century European Heroic Century for mathematics

The 17th century in Europe is known as the Heroic Century for mathematics as in 1600 it passes from an emphasis on geometry to calculus, as formal analysis in 1700 marking the transition from ancient to modern mathematics – a major transition. In 1650 there was a foundation of Greek geometry, symbolic algebra, Hindu/Arabic numerals, logarithms and the combination of algebra and geometry to create coordinate systems and graphs. This set the scene for the birth of calculus via people like Kepler, Fermat, Borrow at Cambridge and others. The two towering figures of Newton and Liebniz (the notation we use today) developed their own versions, Liebniz publishing in 1684. From now on advances were given momentum by the application of calculus to physics, astronomy, and engineering using the calculus tools of functions, curves, series, derivatives, and integrals. The work of Bernoulli was passed on to people like Leonard Euler (1707-1783) the greatest mathematician of the 18th century.

The 19th century challenge to foundations

By the 19th century the foundations of mathematics were under challenge. Euclidian geometry’s parallel postulate led to three angles adding up to 180. Gauss when 15 was convinced it couldn’t be done and in hyperbolic space it was less than 180 used by Einstein and Riemann’s elliptic geometry ‘fat’ triangles. By 1870 the hyperbolic geometry was clearly accepted and Euclid equalled. Gauss (differential geometry and number theory) was one of the greatest mathematicians of the 19th century with contemporaries Lobachevsky (1829) and Bolyai (1832) adding to the work of the day. Fourier worked with trigonometric series and now the foundations of calculus began to look shaky. They depended on limits which depended on real numbers (as yet undefined), reals were based on rationals, rationals on integers, integers on natural numbers. By 1900 the arithmetization of analysis was in place (Gauss, Cauchy, Riemann, Weierstrass, Dedekind, Peano) establishing the foundations of analysis. Cantor developed the idea of ‘the set of all the natural numbers’ that some infinities are bigger than others.

20th century global mathematics

In the last 100 years much more mathematics has been created than in the last 5000, much of it extremely difficult. Of note are the incompleteness theorems of Kurt Gödel (1906-1978) challenged the foundations of mathematics in 1931. That the formal axiomatic system of natural numbers is impossible to prove within that system, that the system is complete. It is also impossible to prove (within the system) the statement that ‘this system is consistent’. American Claude Shannon (1916-2001) in 1948 founded information theory, transmission of information (words, images, sounds) using 1s and 0s.

Whole number – a number without fractions; an integer


Though archaeological indications of numeracy date back into prehistory, mathematics developed in urban environments as a means of facilitating commerce, surveying, engineering, architecture, and building construction, and where academic interests could be shared by a community of people with like interests. This included a special interest in the motions of other-worldly astronomical objects of the night sky, a possible world of the gods. Though, at times, it was clearly treated as a form of intellectual recreation. These are also the kind of communities for which there is a written historical record.

The relationship between complexity of social organization and political and economic power is reflected in the regions and countries where mathematical innovation took place. Complex societies employed an intelligentsia of bureaucrats and academics and the geography of mathematical achievement has followed the geography of political and economic dominance.

The presence of a strong mathematical community is a measure of intellectual aspiration within that community since mathematics is generally recognized as making high intellectual demands.

Applied mathematics that depends on computational capacity has made major progress as once demanding calculations moved from abacus to slide rule to personal calculators. Analogue computers address continuously changing physical phenomena such as electrical, mechanical, or hydraulic quantities while digital computers represent varying quantities symbolically, as their numerical values change.
