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...

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)...

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...

Credit: UNSW/Andrew Kelly ================================================================================ UNSW Sydney scientists have discovered the purpose of a famous 3700-year old Babylonian clay tablet, revealing it is the world's oldest and most accurate trigonometric table, possibly used by ancient mathematical scribes to calculate how to construct palaces and temples and build canals. The new research shows the Babylonians beat the Greeks to the invention of trigonometry - the study of triangles - by more than 1000 years, and reveals an ancient mathematical sophistication that had been...

A 3,700-year-old clay tablet has proven that the Babylonians developed trigonometry 1,500 years before the Greeks and were using a sophisticated method of mathematics which could change how we calculate today. The tablet, known as Plimpton 332, was discovered in the early 1900s in Southern Iraq by the American archaeologist and diplomat Edgar Banks, who was the inspiration for Indiana Jones.

The tablet, known as Plimpton 332, was discovered in the early 1900s... Babylonian mathematics used a base 60, or sexagesimal system, rather than the 10 which is used today. Because 60 is far easier to divide by three, experts studying the tablet, found that the calculations are far more accurate. ... Hipparchus, who lived around 120BC, has long been regarded as the father of trigonometry, with his ‘table of chords’ on a circle considered the oldest trigonometric table. A trigonometric table allows a user to determine two unknown ratios of a right-angled triangle using just one known ratio. But the...

Trigonometry Is Racist! KEVIN D. WILLIAMSON February 27, 2015 An African-American scholar says that emphasis on STEM education is bad for blacks. Earlier today on Sirius XM Urban View, an African-American talk station, the guest was Daryl Scott, president of the Association for the Study of African American Life and History. The conversation turned to STEM — science, technology, engineering, and math — education, and the origins of the ongoing push to encourage institutions and students to focus on those subjects. Can you guess what happened? In 1983, the guest explained, a commission empaneled by the secretary of education issued...

"South Carolina Democratic chairwoman Carol Fowler sharply attacked Sarah Palin [yesterday], saying John McCain had chosen a running mate 'whose primary qualification seems to be that she hasn't had an abortion,' " Politico reports. Fowler later apologized "to anyone who finds my comment offensive." We'll leave the offense to others. We find Fowler's comment revealing and disturbing. And she is not alone in striking this theme. Here is Andrew "Beagle With a Smear" Sullivan of The Atlantic: And then, because [John McCain] could see he was going to lose, ten days ago, he threw caution to the wind and with...

It just keeps getting better. According the head of the South Caolina Democrates, Gov. Palin's main qualification for being VP is that "she hasn't had an abortion" By Nov. 4th, will the "ONE" get even one single vote from a female?

South Carolina Democratic chairwoman Carol Fowler sharply attacked Sarah Palin today, saying John McCain had chosen a running mate " whose primary qualification seems to be that she hasn’t had an abortion.” Palin is an opponent of abortion rights and gave birth to her fifth child, Trig, earlier this year after finding out during her pregnancy that the baby had Down syndrome. Fowler told my colleague Alex Burns in an interview that the selection of an opponent of abortion rights would not boost McCain among many women. “Among Democratic women and even among independent women, I don’t think it helped...

Mathematics students have cause to celebrate. A University of New South Wales academic, Dr Norman Wildberger, has rewritten the arcane rules of trigonometry and eliminated sines, cosines and tangents from the trigonometric toolkit. What's more, his simple new framework means calculations can be done without trigonometric tables or calculators, yet often with greater accuracy. Established by the ancient Greeks and Romans, trigonometry is used in surveying, navigation, engineering, construction and the sciences to calculate the relationships between the sides and vertices of triangles. "Generations of students have struggled with classical trigonometry because the framework is wrong," says Wildberger, whose book...
