And there are probably further discoveries about this ancient peopleâs calculating abilities to be discovered. It has long been known that Babylonian astronomers tracked the planets with incredible precision, but not exactly how until now. The Babyloniansâ elegant solution to the Jupiter problem will be familiar to modern students, who use similar techniques today (except for the wet clay). In algebra, Babylonians apparently had the means to solve quadratic equations (remember those?) and perhaps even higher-order cubic equations. They also estimated Ï to 3.125, very close to the now-accepted value of 3.14. In geometry, for instance, Babylonian mathematicians seem to have been aware of the Pythagorean Theorem long before Pythagoras, and were able to calculate the area of a trapezoid. The Babylonians knew other advanced mathematical tricks. Many fractions are actually easier to reduce than in our base 10 system. Base 60 is also more intuitive than base 10 when calculating arcs of a circle. V << V The given Babylonian numeral can be written as the Hindu-Arabic numeral < Babylonian Numerals Babylonian numerals Hindu-Arabic 1 10 numerals Use the table on the right to write the Babylonian. For larger numbers, those above 3,600, everything was scaled up and the first (leftmost) numeral referred to how many multiples of 3,600 were present. 3,600 might seem like a strange cutoff, but the use of placeholders to make large numbers manageable eluded even the famed mathematicians of ancient Greece.Īlthough unwieldy, base 60 math had a few unexpected advantages. 100 (1 rating) Transcribed image text: Use the table on the right to write the Babylonian numeral as a Hindu-Arabic numeral. The Babylonian number 3 3, for example, meant 3 à 60 + 3, or 183. For numbers above 60, a different system was used. The number concept of âoneâ was depicted as with âVâ symbol, and numbers up to 60 were written out using a combination of these âVâs and â<âs, the symbol for 10. These early achievements may even be more amazing when you consider that, instead of the base 10 number system we use now, theirs was a unique base 60 system. Our knowledge of this is derived from writings much older than these tablets, reaching back to 3000-2000 BCE. âRemarkableâ is a fine description of Babylonian math. As Mathieu Ossendrijver, the scientist behind the discovery, told the Times, the etchings on the tablets display âa remarkably modern concept.â The tablets are dated to about 350 BCE, fifteen centuries before a similar discovery was made in Europe. These Babylonian mathematicians were able to accurately predict the distance Jupiter would travel in 60 days (half the planetâs 120-day arc of visibility from Earth). As The New York Times recently reported, researchers have discovered clay tablets indicating that Babylonian astronomers were able to track Jupiterâs movement across the sky using a very advanced method, graphing the planetâs velocity over time.
