Around 1900 B.C., a pupil within the Sumerian metropolis of Nippur, in what’s now Iraq, copied a multiplication desk onto a clay pill. Some 4,000 years later, that schoolwork survives, as do the coed’s errors (10 occasions 45, for instance, is unquestionably not 270). The work is a reminder that regardless of how elegant or infallible arithmetic could seem, it’s nonetheless a human endeavor.
That’s one lesson I took from “History of Mathematics,” an internet exhibit developed by the National Museum of Mathematics in New York City and Wolfram Research, a computational know-how firm. Bringing collectively the Sumerian pill and greater than 70 different artifacts, the exhibit demonstrates how math has been a common language throughout cultures and all through time.
Divided into 9 “galleries,” the exhibit sums up the event of key matters associated to arithmetic, together with counting, arithmetic, algebra, geometry and prime numbers. Each gallery has a brief timeline and includes a handful of artifacts that function entry factors to discover some milestones in additional depth.

Among the highlights: The oldest identified surviving calculating machine, the Salamis Tablet, is a marble counting board from the Greek island of Salamis courting to 300 B.C. It’s a precursor to the abacus. By shifting pebbles throughout the board, an individual might carry out calculations. An early documented occasion of utilizing a logo for “zero” as a placeholder (to, say, distinguish 1 from 10, 100 or 1,000) seems within the Bakhshali Manuscript, an Indian textual content courting to maybe as early as A.D. 300. The manuscript’s black dots ultimately morphed into the open circles we all know immediately as zeros. Also on show is Al-Jabr. Written in round 820 by Persian polymath Muḥammad ibn Mūsā al-Khwārizmī, the ebook established the sphere of algebra and gave the self-discipline its title. In 1557, the Whetstone of Witte, an English algebra textual content, launched the fashionable equal image.
But the exhibit is greater than only a assortment of enjoyable info. As the galleries clarify, people’ relationship with numbers goes again deep into prehistory. Modern math, nevertheless, stems from the rise of cities, with the necessity to preserve observe of individuals and provides, and to undertake ever extra complicated building initiatives.
Some mathematical rules will need to have been so very important to civilization’s success that they appeared in lots of historic cultures. Take the Pythagorean theorem. The Greek thinker Pythagoras, who lived within the sixth century B.C., famously associated the aspect lengths of a proper triangle within the equation a2 + b2 = c2. But a clay pill reveals that folks in Mesopotamia had labored out the connection greater than 1,000 years earlier. Ancient Chinese and Indian students have been additionally conversant in the connection.
Other math issues have had a number of options. The historical past of counting is suffering from an array of strategies for protecting observe of numbers, from varied types of finger counting to the stringed recording units known as quipus, or khipus, used within the Inca Empire within the 1400s and 1500s. The placement and sorts of knots alongside a quipu’s strings point out totally different numerical values, although researchers immediately are nonetheless attempting to know precisely the best way to interpret the info recorded on these units (SN: 7/6/19 & 7/20/19, p. 12).
Parts of the exhibit assume a excessive degree of mathematical information, similar to a number of the interactive options that give technical explanations behind some artifacts’ mathematical rules. But a bit of “learning journeys” geared toward “kids and others” offers supplies that fill in a number of the lacking particulars from the primary galleries and can enchantment to adults whose reminiscences of highschool or faculty math are fuzzy.
“History of Mathematics” is an enchanting start line for anybody excited about studying in regards to the origins of the mathematical ideas that so many people use every single day however typically take with no consideration.
