Si.427 is a hand tablet from 1900-1600 BC, created by an Old Babylonian surveyor. It’s made out of clay and the surveyor wrote on it with a stylus. Credit: Must credit UNSW Sydney ========================================================================================== A UNSW mathematician has revealed the origins of applied geometry on a 3700-year-old clay tablet that has been hiding in plain sight in a museum in Istanbul for over a century. The tablet – known as Si.427 – was discovered in the late 19th century in what is now central Iraq, but its significance was unknown until the UNSW scientist’s detective work was revealed today. Most...

Stonehenge builders used Pythagoras' theorem 2,000 years before Greek philosopher was born, say experts The builders of Britain’s ancient stone circles like Stonehenge were using Pythagoras' theorem 2,000 years before the Greek philosopher was born, experts have claimed. A new book, Megalith, has re-examined the ancient geometry of Neolithic monuments and concluded they were constructed by sophisticated astronomers who understood lengthy lunar, solar and eclipse cycles and built huge stone calendars using complex geometry One contributor, megalithic expert Robin Heath has even proposed that there exists a great Pythagorean triangle in the British landscape linking Stonehenge, the site from which...

An ancient clay tablet shows that the Babylonians used Pythagorean triples to measure accurate right angles for surveying land.Students may not believe that Pythagoras’ Theorem has real-world uses, but a 3,700-year-old tablet proves that their maths teachers are right. The artifact, named Si.427, shows how ancient land surveyors used geometry to draw boundaries accurately. Discovered in central Iraq in 1894, Si.427 sat in a museum in Istanbul for over a century. Now, mathematician Dr Daniel Mansfield from the University of New South Wales, Australia, has studied the clay tablet and uncovered its meaning. “Si.427 dates from the Old Babylonian (OB)...

Calcea Johnson and Ne'Kiya Jackson have added four further novel proofs of the theorem that had also not been published before, and left clues for another five. Teen mathematicians Ne’Kiya Jackson (left) and Calcea Johnson (right) who have done what mathematics texts said was impossible, finding a non-circular trigonometric proof of Pythagoras Theorem. Image Credit: Calcea Johnson High school students Calcea Johnson and Ne'Kiya Jackson did something in 2023 that most mathematicians had thought impossible: They discovered a way to prove Pythagoras' theorem using trigonometry that did not depend on circular reasoning. Now, they have published their work in a...

Wow! Two high school seniors solved a mathematical puzzle that has stumped mankind for 2,000 years. "60 Minutes" did a nice feature on the pair, and earned themselves a Community Note in the process. Two high school seniors solved a mathematical puzzle that was thought to be impossible for 2,000 years. @BillWhitakerCBS reports, Sunday. https://t.co/mEN4CWeXMW pic.twitter.com/iPhsZiERsc — 60 Minutes (@60Minutes) May 2, 2024 Readers added context they thought people might want to know This puzzle was solved 15 years ago… I studied physics and this isn't a discovery, it was published in a paper over 15 years ago, they've just...

It is one the oldest mathematical problems in the world. Several centuries ago, the twin primes conjecture was formulated. As its name indicates, this hypothesis, which many science historians have attributed to the Greek mathematician Euclid, deals with prime numbers, those divisible only by themselves and by one (2, 3, 5, 7, 11, etc.). Under this assumption, there exists an infinite number of pairs of prime numbers whose difference is two, called twin primes (e.g., 3 and 5), but nobody has been able to confirm this so far.

The ‘music of the spheres’ was born from the effort to use numbers to explain the universeAn image of a white half circle at the bottom-center on a starry background. There are 8 arches spreading away from the circle. The Pythagoreans believed that the motions of the heavenly bodies, with just the right ratios of their distances from a central fire, made pleasant music — a concept that evolved into the “music of the spheres.” If you’ve ever heard the phrase “the music of the spheres,” your first thought probably wasn’t about mathematics. But in its historical origin, the music...

At an American Mathematical Society meeting, high school students presented a proof of the Pythagorean theorem that used trigonometry—an approach that some once considered impossibleTwo high school students have proved the Pythagorean theorem in a way that one early 20th-century mathematician thought was impossible: using trigonometry. Calcea Johnson and Ne’Kiya Jackson, both at St. Mary’s Academy in New Orleans, announced their achievement last month at an American Mathematical Society meeting. “It’s an unparalleled feeling, honestly, because there’s just nothing like it, being able to do something that ... people don’t think that young people can do,” Johnson told WWL-TV, a...
