A Reagan Foundation Interview with Pat Buchanan
"The Story of English: The Mother Tongue" with Robert MacNeil
This second episode in "The Story of English" traces the history of the language in terms of successive invasions of the British Isles, from the Anglo-Saxons through the Norman French in 1066.
Advanced Imaging Reveals a Computer 1,500 Years Ahead of Its Time
X-rays and advanced photography have uncovered the true complexity of the mysterious Antikythera mechanism, a device so astonishing that its discovery is like finding a functional Buick in medieval Europe.
In 1900, some divers found the wreck of a Roman vessel off the Greek island of Antikythera. Among the other treasures remanded to the Greek government was an unassuming corroded lump. Some time later, the lump fell apart, revealing a damaged machine of unknown purpose, with some large gears and many smaller cogs, plus a few engraved words in Greek. Early studies suggested it was some type of astronomical time-keeping device – researcher Derek J. de Solla Price laid the groundwork by establishing initial tooth counts and suggesting that the device followed the Metonic cycle, a 235-month pattern commonly used to predict eclipses in the ancient world.
The full function and beauty of the Antikythera device remained hidden until recent studies subjected it to more advanced imaging techniques. First, it was photographed using a technique that exposed the surfaces to varying lighting patterns. This created different levels of contrast that allowed the researchers to read far more of the inscribed Greek text than was previously possible. Then, x-ray imaging was used to create full 3-D computer models of the mechanism, which revealed for the first time some of the more complex and detailed gear interactions. The Greek National Archaeological Museum's discovery of some boxes filled with 82 additional mechanism fragments added new information as well.
The findings, published in Nature, are probably best described as "mind blowing." Devices with this level of complexity were not seen again for almost 1,500 years, and the Antikythera mechanism's compactness actually bests the later designs. Probably built around 150 B.C., the Antikythera mechanism can perform a number of functions just by turning a crank on the side.
Using nothing but an ingenious system of gears, the mechanism could be used to predict the month, day and hour of an eclipse, and even accounted for leap years. It could also predict the positions of the sun and moon against the zodiac, and has a gear train that turns a black and white stone to show the moon's phase on a given date. It is possible that it could also show the astronomical positions of the planets known to the ancients: Mercury, Venus, Mars, Jupiter and Saturn.
The Antikythera mechanism wasn't just a scientific tool – it also had a social purpose. The Greeks held major athletic competitions (such as the Olympics) every two or four years. A small dial within the Metonic dial showed the dates of these important events.
The true genius of the mechanism goes beyond even the complex calculations and craftsmanship of a mechanical calendar. For example, the ancients didn't know that the moon has an elliptical orbit, so they didn't know why it sometimes slowed or sped up as it moved through the zodiac. The mechanism's creator used epicyclic gears, also known as planetary gears, with a "pin-and-slot" mechanism that mimicked this apparent shifting in the moon's movement. This use of epicyclic gears is far ahead of what anyone suspected ancient technology was capable of. Scientific American has a two-part video about the mechanism and the imaging techniques used in the research.
The mystery of who built the Antikythera mechanism remains. It has been linked to renowned ancient inventor Archimedes by the writings of Cicero, but this particular device was built after Archimedes' death. Still, the engraved words revealed by the new photos pinpoint the device's origin to Corinth, or possibly Corinthian colonies. Sicily was such a colony, and the Sicilian city of Syracuse was Archimedes' headquarters. The researchers theorize that the Antikythera mechanism is based on an Archimedian design, and might even have been built by a workshop carrying on his technological tradition. But if the design has been "industrialized" in such a way, why have we never found another one like it? Mysteries remain.
The complexity of the mechanism shows that ancient humans were capable of intellectual and engineering feats that boggle our modern minds (and it puts the lie to all those "ancient astronaut" theories). The upheavals of war and natural disasters over 2,000 years have probably caused us to lose many more works and wonders that will never be found.

KFC Feels Global Heat Over Australian Ad
Black folks love chicken. There, I said it. This stereotype, like all stereotypes, has a good dose of truth in it. In fact, I'd go so far as to make another generalization and say we don't care if its fried, baked, roasted, grilled, barbecued, fricasseed, jerked, pulled, or even boiled. We just love us some soul bird.
What we don't like is the lingering racist connotations that are associated with eating poultry (don't even get me started on swine), which is probably the real reason some black folks are upset by a controversial KFC ad that has some claiming the company is perpetuating racist stereotypes.
The KFC ad depicts a frustrated, white Australian cricket fan sitting among a crowd of black people who are happily dancing to the beat of steel drums while rooting for their team, which is apparently from a Caribbean nation. How does he get them to see things his way? He offers them a bucket of chicken and they quickly change their tune. As they grab pieces of chicken from the bucket, he looks at the camera and says, "Too easy."
Elephants Attack in Orissa Exactly One Year After Persecution of Christians
In recent months, herds of wild elephants have begun to storm villages that are home to some of the worst persecutors of Christians during the troubles. In one village, where in August a year ago the Christians had to run for their lives while their homes were being destroyed by rioters, a herd of elephants emerged from the surrounding jungle exactly one year later, in July 2009, at the same time of the day of the attack.
These elephants first attacked a rock crusher machine owned by a key leader of the persecution movement. They then went on to destroy his house and farms.
Hundreds of villagers have been forced to take shelter in camps in the Indian state of Orissa after repeated attacks by a herd of elephants.
Seven people have been killed and several others injured in attacks by a herd of 12-13 elephants over the past few weeks in Kandhamal district.
Over 2,500 people living in 45 villages have been affected by the attacks, district chief Krishen Kumar said.
It is, however, unclear why this herd of elephants migrated from the Lakheri sanctuary in a neighbouring district. He said the herd had travelled some 300km into Kandhamal, and even entered a town in the district. Wildlife officials were camping at the site of the attacks and trying to find out why the elephants had come out of their sanctuary. The villagers say elephants attack their areas in herds, causing heavy destruction.
Gaining momentum, they rampaged through other non-Christian homes, demolishing gardens and singling out the home of persecutors, leaving Christian homes untouched.
These strange attacks have spread, and according to a report, the elephants have already destroyed more than 700 houses in 30 villages, and killed five people. Nobody in this area has seen or even imagined the unique appearance of a herd of wild elephants such as this. The elephants are not ordinary elephants; they appear to be on a mission.
Typically, smaller elephants enter a village first, appearing to survey the community. They then rejoin the larger herd, and larger elephants soon follow and get the job done.
The ministry partner in India stated “We think that it might have something to do with the avenging the blood of martyrs. In fact the fear of God has fallen on the local people, who have labeled these elephants “Christian elephants.”
With little help coming from the administration, the villagers have taken to road blockades. "The elephants have destroyed crops and selected houses. But officials too express helplessness. "There is no permanent habitat of elephants in Sundargarh. They come from Bihar, Chhattisgarh and Jharkhand where their habitats have shrunk. But is not clear how and why these elephants reached Orissa.
'Toughest Sheriff in America' Facing Federal Harrassment
Maricopa County Sheriff Joe Arpaio, the self-proclaimed "toughest sheriff in America," at a news conference in Mesa, Ariz.
Two officials said Thursday night they have been subpoenaed to answer questions next week before a federal grand jury about a high-profile Arizona sheriff who gained attention for aggressively cracking down on illegal immigration.
In statements read by a county spokesman, Maricopa County Manager David Smith and Deputy County Manager Sandi Wilson said they met with a federal prosecutor to discuss the case and will testify Wednesday.
