Modern society's focus on credentials has created a two-tiered system, where multi-talented individuals are criticized, and elites oversee a dependent underclass. The songwriter, actor, country/western singer, musician, U.S. Army veteran, helicopter pilot, accomplished rugby player and boxer, Rhodes scholar, Pomona College and University of Oxford degreed, and summa cum laude literature graduate, Kris Kristofferson, recently died at 88. Americans may have known him best for writing smash hits like “Me and Bobby McGee” and “For the Good Times,” his wide-ranging, star-acting roles in A Star is Born and Pat Garrett and Billy the Kid, his numerous solo albums, especially with...

Ancient Egypt, renowned for its rich culture and enduring legacy, was a civilization of remarkable ingenuity and innovation. From monumental architecture to intricate writing systems, the ancient Egyptians left an indelible mark on human history with their numerous inventions and technological advancements. Here, we explore fifteen of the most significant inventions that exemplify the ingenuity and creativity of this ancient civilization. 1. Papyrus: Among the most enduring contributions of ancient Egypt is the invention of papyrus, a paper-like material made from the papyrus plant. This versatile writing medium revolutionized communication, allowing Egyptians to record their history, literature, and administrative documents...

One legend about Archimedes, a famous Greek mathematician and physicist, states that he was killed during Syracuse’s siege in 212 B.C. According to the most common narrative, he was sketching geometric figures when a bounty-seeking Roman soldier burst into his study. “Do not disturb my circles,” said Archimedes, but the simpleton Roman legionnaire, who knew nothing about mathematics, struck him with a sword. History has repeatedly evidenced over the last two millennia that ignoramuses often change history. Geniuses who fall victim to uncivilized invaders, uncultured neighbors, or moronic rulers are well known. Postmortems cannot alleviate the loss of a great...

True or false? Eight hundred years ago, a monk did his best to erase a copy of some of Archimedes' most important work, putting some prayers on the parchment instead, and the words of the great Greek mathematician were then gone forever. False. At Stanford University in California, some scientists are using X-ray technology to make the older ink shine through the later scribbling, thereby recovering a remarkable piece of history and doing something else to boot. They are giving us an illustration among many of how a civilization made great in part by the Greeks of antiquity remains great...

The silent ceramic objects that survive from medieval Indian Ocean trade carry incredible stories of a time when South Asia had the upper hand over China...In the 830s CE, a ship tried to make a daring crossing. Navigating treacherous reefs and shoals, it was attempting to move from the South China Sea to the Sunda Strait between Java and Sumatra. After a brief stop there, it intended to catch the monsoon winds to India. This attempt failed, and the ship’s contents — ranging from marvellously carved golden plates to glazed ceramics, from a diplomat’s ink-stone to a small toy dog...

Archimedes posed a riddle about herding cattle... His problem ultimately boiled down to an equation that involves the difference between two squared terms, which can be written as x2 – dy2 = 1. Here, d is an integer — a positive or negative counting number — and Archimedes was looking for solutions where both x and y are integers as well. This class of equations, called the Pell equations, has fascinated mathematicians over the millennia since. Indian mathematician Brahmagupta, and later the mathematician Bhāskara II, provided algorithms to find integer solutions to these equations. In the mid-1600s, the French mathematician...

"The amazing thing is the mechanical engineering aspect," says James Evans, a physicist and science historian at the University of Puget Sound in Tacoma, Wash. He is part of an international group working to crack the puzzle of the device's origins and purpose. Evans recently added a new twist with an analysis that suggests it dates to 205 B.C. -- as much as a century earlier than previously believed. If he's right, it is more likely that the Antikythera Mechanism was inspired by the work of the legendary Greek mathematician Archimedes. It would also mean the device was built at...

For the last time: Archimedes did not invent a death ray. But more than 2,200 years after his death, his inventions are still driving technological innovations — so much so that experts from around the world gathered recently for a conference at New York University on his continuing influence. The death ray legend has Archimedes using mirrors to concentrate sunlight to incinerate Roman ships attacking his home of Syracuse,... --snip-- With his law of buoyancy, he was able to determine whether a paraboloid (a shape similar to the nose cone of a jetliner) would float upright or tip over, a...

Report of 1 Kilo Gold Bar Filled with Tungsten Found in UK March 26, 2012 “What appears to be a tungsten filled gold bar has been found – this time in the UK. It is believed that a scrap dealer bought the Metalor 1 kilo gold bar of 99.98% purity from a member of the public. Metalor are a leading international gold refiner and bar manufacturer, headquartered in Zurich. The bar appears to have been tampered with and may have had holes drilled into it or melted out and then had tungsten rods inserted or tungsten poured into the holes....

BALTIMORE — “The Archimedes Palimpsest” could well be the title of a Robert Ludlum thriller, though its plot’s esoteric arcana might also be useful for Dan Brown in his next variation on “The Da Vinci Code.” It features a third-century B.C. Greek mathematician (Archimedes) known for his playful brilliance; his lost writings, discovered more than a hundred years ago in an Istanbul convent; and various episodes involving plunder, pilferage and puzzling forgeries. The saga includes a monastery in the Judaean desert, a Jewish book dealer trying to flee Paris as the Nazis closed in, a French freedom fighter and an...

One of the most complete descriptions of a ship from antiquity is that described by the Greek writer Athenaeus. Writing in the second century ce, but basing his account on more contemporary descriptions (now lost), he described a huge grain ship built by Hieron II, king of Syracuse from 269 to 215 bce. Lionel Casson considers this to be the largest ship built in antiquity... There were cabins for 142 first-class passengers on the second deck in addition to accommodations for steerage, the lower deck being reserved for cargo and the upper deck for soldiers, said to number 400. The...

WASHINGTON -- President Barack Obama will appear on an episode of "Mythbusters," a television show that uses science to determine the truth behind urban legends. The White House says the episode will air Dec. 8 on the Discovery Channel. Discovery says the episode considers this question: Did Greek scientist Archimedes set fire to an invading Roman fleet using only mirrors and the reflected rays of the sun?

President Obama and Discovery Channel announced today that the chief executive will appear on the Dec. 8 episode of Mythbusters. And surprisingly, the myth being busted has nothing to do with either Islam or Kenyan birth certificates. On the episode, Obama will ask Adam Savage and Jamie Hyneman to test whether it was possible for the Greek scientist Archimedes, as told in story, to have set fire to an invading fleet using a giant mirror and the reflected rays of the sun. Which forces me to ask: What the hell is the government secretly planning to do with a giant...

For a president under siege, maybe this could help. In an episode of “Mythbusters” on the Discovery Channel to be shown on Dec. 8, President Obama will help determine whether the Greek scientist Archimedes really set fire to an invading Roman fleet using only mirrors and the reflected rays of the sun. Legend has it that during the Siege of Syracuse, circa 214 B.C., Archimedes destroyed the enemy ships with fire, the result of a “heat ray” involving a series of mirrors set up on the coast. But the question has long remained: Did it really happen that way? “Mythbusters”...

Greek inventor Archimedes is said to have used mirrors to burn ships of an attacking Roman fleet. But new research suggests he may have used steam cannons and fiery cannonballs instead. A legend begun in the Medieval Ages tells of how Archimedes used mirrors to concentrate sunlight as a defensive weapon during the siege of Syracuse, then a Greek colony on the island of Sicily, from 214 to 212 B.C. No contemporary Roman or Greek accounts tell of such a mirror device, however. Both engineering calculations and historical evidence support use of steam cannons as "much more reasonable than the...

For seventy years, a prayer book moldered in the closet of a family in France, passed down from one generation to the next. Its mildewed parchment pages were stiff and contorted, tarnished by burn marks and waxy smudges. Behind the text of the prayers, faint Greek letters marched in lines up the page, with an occasional diagram disappearing into the spine. The owners wondered if the strange book might have some value, so they took it to Christie's Auction House of London. And in 1998, Christie's auctioned it off—for two million dollars. For this was not just a prayer book....

A long-lost text by the ancient Greek mathematician shows that he had begun to discover the principles of calculus. ~~~snip~~~ An intensive research effort over the last nine years has led to the decoding of much of the almost-obliterated Greek text. The results were more revolutionary than anyone had expected. The researchers have discovered that Archimedes was working out principles that, centuries later, would form the heart of calculus and that he had a more sophisticated understanding of the concept of infinity than anyone had realized. ~~~~snip~~~~

For 2,000 years, the document written by one of antiquity's greatest mathematicians was ill treated, torn apart and allowed to decay. Now, US historians have decoded the Archimedes book. But is it really new? When the Romans advanced to Sicily in the Second Punic War and finally captured the proud city of Syracuse, one of their soldiers met an old man who, surrounded by the din of battle, was calmly drawing geometric figures in the sand. "Do not disturb my circles," the eccentric old man called out. The legionnaire killed him with his sword. That, at least, is the legend....

CUT OFF by a muddy pool fed by an ancient river, close to the bottom of an excavation 30 metres deep, archaeologists exploring a villa buried by the eruption of Vesuvius in AD79 have found two great doors of carbonised wood. Behind them could lie a lost treasure trove of Roman scrolls, scholars say, part of the celebrated lost library of the Villa of the Papyri. However, a unique chance to recover great classical masterpieces, lost to humanity for 2,000 years, could fall victim to flooding or a new blast from the volcano Vesuvius, they warn. The leading names of...

THE book cost $2 million at auction, but large sections are unreadable. Some of its 348 pages are torn or missing and others are covered with sprawling purple patches of mildew. Sooty edges and water stains indicate a close escape from a fire.
