    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...

    The 22 million digit number and the amazing maths behind primes January 21, 2016 by Steve Humble, The Conversation Primes: here be magic. Credit: Shutterstock It is a quite extraordinary figure. Dr Curtis Cooper from the University of Central Missouri has found the largest-known prime number - written (274207281)-1. It is around 22m digits long and, if printed in full, would take you days to read. Its discovery comes thanks to a collaborative project of volunteers who use freely available software called GIMPS (Great Internet Mersenne Prime Search) to search for primes. A number which can only be divided by...

    Finite formula found for partition numbersFor centuries, some of the greatest names in math have tried to make sense of partition numbers, the basis for adding and counting. Many mathematicians added major pieces to the puzzle, but all of them fell short of a full theory to explain partitions. Instead, their work raised more questions about this fundamental area of math. On Friday, Emory mathematician Ken Ono will unveil new theories that answer these famous old questions. Ono and his research team have discovered that partition numbers behave like fractals. They have unlocked the divisibility properties of partitions, and developed...

    An illuminating exhibition of thirteen ancient Babylonian tablets, along with supplemental documentary material, opens at New York University's Institute for the Study of the Ancient World (ISAW) on November 12, 2010. Before Pythagoras: The Culture of Old Babylonian Mathematics reveals the highly sophisticated mathematical practice and education that flourished in Babylonia -- present-day Iraq -- more than 1,000 years before the time of the Greek sages Thales and Pythagoras, with whom mathematics is traditionally said to have begun. The tablets in the exhibition, at once beautiful and enlightening, date from the Old Babylonian Period (ca. 1900-1700 BCE). They have been...

    Archeologists to Unearth Ancient Egyptian City Wed Aug 28,10:25 AM ET By Heba Kandil CAIRO, Egypt (Reuters) - In a squalid suburb of northeast Cairo, a red granite obelisk towering above ramshackle homes is the last visible vestige of a nearly 7,000-year-old city where ancient Egyptians believed life began. Archeologists say they soon expect to unearth other artifacts and unlock the secrets of the sun-cult city of On buried beneath today's suburbs of Ain Shams, which means "eye of the sun" in Arabic, and the adjacent area of Matariya. "It's a matter of a few months and the supreme council...

    TWO REVOLUTIONS, TWO VIEWS OF MAN By Jean F. Drew As every American schoolchild has been taught, in Western history there were two great sociopolitical revolutions that took place near the end of the eighteenth century: The American Revolution of 1775; and the French, of 1789. Children are taught that both revolutions were fought because of human rights in some way; thus bloody warfare possibly could be justified, condoned so long as the blood and treasure were shed to protect the “rights of man.” The American schoolchild is assured that the American and French revolutions were both devoted to the...

    March 14, 2007 — The leader of the most powerful empire in the world invades a small country to avenge his father's failure to do so years ago. His army is relentlessly attacked by a proud group of insurgents who denounce the empire's decadence. The leader of a brave fighting force vows to defend freedom at all costs against an enemy from the Middle East. To rally his troops, he makes a speech, declaring, "The world will know that free men stood against a tyrant." Is one of them President Bush? That's the question on the minds of some political...
  • 1200-year-old problem 'easy' [dividing by zero]

    BBC ^ | 12/8/06
    Schoolchildren from Caversham have become the first to learn a brand new theory that dividing by zero is possible using a new number - 'nullity'. But the suggestion has left many mathematicians cold. Dr James Anderson, from the University of Reading's computer science department, says his new theorem solves an extremely important problem - the problem of nothing. "Imagine you're landing on an aeroplane and the automatic pilot's working," he suggests. "If it divides by zero and the computer stops working - you're in big trouble. If your heart pacemaker divides by zero, you're dead." Computers simply cannot divide by...

    Dr. Dennis Danielson, professor of English at the University of British Columbia, has some advice: Don't believe everything you read in textbooks. Speaking at the meeting of the American Scientific Affiliation in July, Danielson noted that the conventional wisdom says that when scholars thought the earth was the center of the universe, then humans were the king of the cosmic hill, creatures in God's image. But when Copernicus discovered Earth orbited the Sun, man concluded that he was a mere animal -- or so the story goes. After nearly a decade of research, however, Danielson, who has specialized in linking...

    Published online: 28 February 2006; | doi:10.1038/news060227-3 Were ancient Minoans centuries ahead of their time? Unprecedented mathematical knowledge found in Bronze Age wall paintings. Philip Ball Did the Minoans understand the Archimedes' spiral more than 1,000 years before him? A geometrical figure commonly attributed to Archimedes in 300 BC has been identified in Minoan wall paintings dated to over 1,000 years earlier. The mathematical features of the paintings suggest that the Minoans of the Late Bronze Age, around 1650 BC, had a much more advanced working knowledge of geometry than has previously been recognized, says computer scientist Constantin Papaodysseus of...

    One of the greatest engineering achievements of ancient times is a water tunnel, 1,036 meters (4,000 feet) long, excavated through a mountain on the Greek island of Samos in the sixth century B.C. It was dug through solid limestone by two separate teams advancing in a straight line from both ends, using only picks, hammers, and chisels. This was a prodigious feat of manual labor. The intellectual feat of determining the direction of tunneling was equally impressive. How did they do this? No one knows for sure, because no written records exist. When the tunnel was dug, the Greeks had...

    We can forget all the ideas crediting Atlanteans or space aliens with building the Great Pyramid of Giza, and instead imagine ourselves travelling back in time in H G Wells's time machine to try and work out not how the ancient Egyptians built this enormous edifice, because this lies beyond our present understanding, but rather what we can best judge to be its most appropriate proportions. Then, however, there were no electronic calculators, only ropes and rods. Constructing right angles at the four corners of a pyramid is easy. To do it, history tells us that the Egyptians were aware...

    From the idea that our universe is one among many, to the revelation that mathematician Pythagoras didn't actually invent the Pythagorean theorem, here are eight shocking things we learned from reading physicist Stephen Hawking's new book, "The Grand Design," written with fellow physicist Leonard Mlodinow of Caltech. This book, covering major questions about the nature and origin of the universe, was released Sept. 7 by its publisher, Bantam. 1. The past is possibility According to Hawking and Mlodinow, one consequence of the theory of quantum mechanics is that events in the past that were not directly observed did not happen...

    The “Cartesian Split” Is a Hallucination; Ergo, We Should Get Rid of It by Jean F. Drew The Ancient Heritage of Western Science The history of science goes back at least two and a half millennia, to the pre-Socratics of ancient Greece. Democritus and Leucippus were the fathers of atomic theory — at least they were the first thinkers ever to formulate one. Heraclitus was the first thinker to consider what in the modern age developed as the laws of thermodynamics. Likewise Plato’s Chora, in the myth of the Demiurge (see Timaeus), may have been the very first anticipation of...

    What Is a Cosmos? The Greek Idea of Cosmos and its Contemporary Meaning By David Fideler The Greek word cosmos cannot be translated into a single English word, but refers to an equal presence of order and beauty. When the Greek philosopher Pythagoras first called the universe a cosmos, he did so because it is a living embodiment of nature’s order, beauty, and harmony. The fact that the physical world embodies beauty and harmony can be demonstrated in many ways, but rational proof is only required when we have forgotten our own connection with the underlying fabric of life. When...

    THE MUSIC OF THE SPHERES, OR THE METAPHYSICS OF MUSIC . . . According to tradition, the harmonic structure of music was discovered by Pythagoras about the fifth century B.C. Pythagoras experimented with a stretched piece of cord. When plucked, the cord sounded a certain note. When halved in length and plucked again, the cord sounded a higher note completely consonant with the first. In fact, it was the same note at a higher pitch. Pythagoras had discovered the ration 2:1, of the octave. Further experiments, plucking the strings two-thirds of its original length produced a perfect fifth in the...
