Is This a New Theory About the Garden of Eden?

From Yahoo News
Lost Civilization May Have Existed Beneath the Persian Gulf
Jeanna Bryner

livescience.com – Fri Dec 10, 7:25 am ET

Veiled beneath the Persian Gulf, a once-fertile landmass may have supported some of the earliest humans outside Africa some 75,000 to 100,000 years ago, a new review of research suggests.

At its peak, the floodplain now below the Gulf would have been about the size of Great Britain, and then shrank as water began to flood the area. Then, about 8,000 years ago, the land would have been swallowed up by the Indian Ocean, the review scientist said.

The study, which is detailed in the December issue of the journal Current Anthropology, has broad implications for aspects of human history. For instance, scientists have debated over when early modern humans exited Africa, with dates as early as 125,000 years ago and as recent as 60,000 years ago (the more recent date is the currently accepted paradigm), according to study researcher Jeffrey Rose, an archaeologist at the University of Birmingham in the U.K.

"I think Jeff's theory is bold and imaginative, and hopefully will shake things up," Robert Carter of Oxford Brookes University in the U.K. told LiveScience. "It would completely rewrite our understanding of the out-of-Africa migration. It is far from proven, but Jeff and others will be developing research programs to test the theory."

Viktor Cerny of the Archaeogenetics Laboratory, the Institute of Archaeology, in Prague, called Rose's finding an "excellent theory," in an e-mail to LiveScience, though he also points out the need for more research to confirm it.

The findings have sparked discussion among researchers, including Carter and Cerny, who were allowed to provide comments within the research paper, about who exactly the humans were who occupied the Gulf basin.

"Given the presence of Neanderthal communities in the upper reaches of the Tigris and Euphrates River, as well as in the eastern Mediterranean region, this may very well have been the contact zone between moderns and Neanderthals," Rose told LiveScience. In fact, recent evidence from the sequencing of the Neanderthal genome suggests interbreeding, meaning we are part caveman. [Part caveman? This is baloney -so-called "Neanderthal" weren't hunch-backed slope-browed hairy "apemen" just because they lived in caves. So-called "Cro-Magnon" man also lived in caves, as did so-called "Modern" humans in France and Spain during the last great Ice Age. Duh. This type of writing continues to feed into ignorant and proven to be incorrect stereotypes.]

Watery refuge

The Gulf Oasis would have been a shallow inland basin exposed from about 75,000 years ago until 8,000 years ago, forming the southern tip of the Fertile Crescent, according to historical sea-level records.

And it would have been an ideal refuge from the harsh deserts surrounding it, with fresh water supplied by the Tigris, Euphrates, Karun and Wadi Baton Rivers, as well as by upwelling springs, Rose said. And during the last ice age when conditions were at their driest, this basin would've been at its largest.

In fact, in recent years, archaeologists have turned up evidence of a wave of human settlements along the shores of the Gulf dating to about 7,500 years ago.

"Where before there had been but a handful of scattered hunting camps, suddenly, over 60 new archaeological sites appear virtually overnight," Rose said. "These settlements boast well-built, permanent stone houses, long-distance trade networks, elaborately decorated pottery, domesticated animals, and even evidence for one of the oldest boats in the world."

Rather than quickly evolving settlements, Rose thinks precursor populations did exist but have remained hidden beneath the Gulf.

"Perhaps it is no coincidence that the founding of such remarkably well developed communities along the shoreline corresponds with the flooding of the Persian Gulf basin around 8,000 years ago," Rose said. "These new colonists may have come from the heart of the Gulf, displaced by rising water levels that plunged the once fertile landscape beneath the waters of the Indian Ocean."

Ironclad case?

The most definitive evidence of these human camps in the Gulf comes from a new archaeological site called Jebel Faya 1 within the Gulf basin that was discovered four years ago. There, Hans-Peter Uerpmann of the University of Tubingen in Germany found three different Paleolithic settlements occurring from about 125,000 to 25,000 years ago. That and other archaeological sites, Rose said, indicate "that early human groups were living around the Gulf basin throughout the Late Pleistocene."

To make an ironclad case for such human occupation during the Paleolithic, or early Stone Age, of the now-submerged landmass, Rose said scientists would need to find any evidence of stone tools scattered under the Gulf. "As for the Neolithic, it would be wonderful to find some evidence for human-built structures," dated to that time period in the Gulf, Rose said.

Carter said in order to make for a solid case, "we would need to find a submerged site, and excavate it underwater. This would likely only happen as the culmination of years of survey in carefully selected areas."

Cerny said a sealed-tight case could be made with "some fossils of the anatomically modern humans some 100,000 years old found in South Arabia."

And there's a hint of mythology here, too, Rose pointed out. "Nearly every civilization living in southern Mesopotamia has told some form of the flood myth. While the names might change, the content and structure are consistent from 2,500 B.C. to the Genesis account to the Qur'anic version," Rose said.

Perhaps evidence beneath the Gulf? "If it looks like a duck, and quacks like a duck, we have at least to consider the possibility that we have a small aquatic bird of the family Anatidae on our hands," said Rose, quoting Douglas Adams.
*******************************************************************
I like a Rose who quotes one of my favorite analogies about the proverbial duck :) 

As far as I am aware, of the four rivers named in the biblical description of the Garden of Eden in Genesis, only two have been identified: The Tigris and the Euphrates. Here is a transcription of the account from the King James Version of the Bible:

Gen. 2:8: And the Lord God planted a garden eastward in Eden; and there he put the man whom he had formed. (10) and a river went out of Eden to water the garden; and from thence it was parted, and became into four heads. (11) The name of the first is Pi-son: that is it which compasseth the whole land of Havilah, where there is gold; (12) And the gold of that land is good: there is bdellium and the onyx stone. (13) And the name of the second river is Gi-hon: the same is it that compasseth the whole land of Ethiopia. (14) And the name of the third river is Hid-de-kel: that is it which goeth toward the east of Assyria. and the fourth river is Eu-phra-tes.
Here are the four rivers named in the article: Tigris, Euphrates, Karun and Wadi Baton Rivers.

Perhaps the Garden of Eden (actually, east of Eden) has never been successfully located because it now sits under the Indian Ocean. We shall see, I hope. It depends upon future funding for archaeological expeditions and will take years to locate and excavate underwater settlements, assuming of course, that they ever existed to begin with and that the remains still do exist beneath the seas.

Quah Seng Sun Hits a Grand Slam on Female Chessplayers

Thank you, Quah Seng Sun, for saying in this article what needs to be said, something long overdue.  You are a brave man!

Women and chess
Chess
By Quah Seng Sun

Women’s chess is no longer a poor cousin to men’s chess.

MANY years ago, I was asked in a casual conversation my opinion about women’s chess. Can women really play chess as well as men, this friend of mine wanted to know. I was about to answer him but I hesitated.

It wasn’t that I was uncomfortable to give him an immediate answer but somehow, a wild thought raced through my head. Was it Bobby Fischer who once said that he could give a knight handicap in a game against any woman chess player and still win?

Fifty or 60 years ago, many people could very well have laughed with Fischer.

But not today. Anyone who dares to give even a pawn handicap against the top women chess players will be asking for a lot of unnecessary trouble.

You see, women’s chess is no longer a poor cousin to men’s chess. After all, chess as played by men or women is still the same game. Chess still uses the same grey matter “up there” for thinking and evaluation.

Besides, since the days of Pia Cramling and Judit Polgar, who started the trend of women competing in men’s or open tournaments and playing successfully in them, the myth has well been exploded.

To a large extent, the World Chess Federation has made sure that there should no longer be discrimination. A long time ago at the Chess Olympiads, women’s chess teams consisted of only two players and one reserve. Today, there are four players and either one or two reserve players, same as the men’s teams.

Where chess titles are concerned, women chess players have as many opportunities to earn the full chess grandmaster title.

In the past, the highest title they could hope to attain was the woman grandmaster title which today, is about at the same level as an international master.

There’s also the women’s equivalent of the (men’s) world chess championship and since about a week ago, the latest women’s world chess championship is currently going on in Antakya, Turkey.

But unlike the latest men’s world chess championship which was played as a match, the present women’s world chess championship is still run as a knock-out.
The event started off with a 64-player field in the first round and since then, the number of players are halved with each progressive round.

Today is the start of the third round, so there will only be 16 players left. Each of these knock-out rounds are played as a mini-match of two games at normal regulation time control and should tie-break games be required, these are played with rapid chess rules. The sixth round will pit the two final survivors together and they will then play four games to decide the new women’s world chess champion.

I know there are people who favour this type of knock-out event as they feel that it creates more excitement and the defending champion shouldn’t get a free ride to the final round but personally, I would prefer an official challenger to emerge from this knock-out event who would then go on to challenge the defending champion for the title. It makes for more prestige.

Nevertheless, these are the regulations already agreed for this current championship. Perhaps we’ll see a change for the next cycle.

As it stands, there’s always the chance that we may not have Russia’s Alexandra Kosteniuk advancing all the way to the final round.

Kosteniuk is the defending women’s world champion and is the top seed. She got through the first round but there are no results yet for the second round as I write this.

So far, except for the elimination of the eighth seed, Pia Cramling, in the first round, there have been no other surprises among the top seeds.

Also going through to the second round were notable players like India’s Humpy Koneru, China’s Hou Yifan (who lost the final to Kosteniuk in 2008), Bulgaria’s Antoaneta Stefanova (women’s world champion from 2004 to 2006), Ukraine’s Kateryna Lahno, Georgia’s Maya Chiburdanidze (women’s world champion from 1978 to 1991) and Qatar’s Zhu Chen (formerly from China and women’s world champion from 2001 to 2004).

Humpy is the second seed in the championship and Hou is the third seed.

If they proceed through successfully round after round, they should be meeting in the fifth round and one of them will be eliminated.

****************************************************************
Given the level of play of today's top female players, there is no excuse for FIDE to continue to run the Women's World Chess Championship as a knock-out event, which has since been discarded as FIDE's preferred option for the Men's World Chess Championship. As has been shown over and over again, anything can - and does - happen over the course of two games plus rapid and blitz play-offs.  That does not necessarily mean that the best players finish at the top and compete against each other for the title.  It's time that FIDE recognize that the Women's title is just as important as the "Open" - that is, the Men's - title, and put them on an equal footing.

Here is a summary of the Round 2 play-off action from the official website:


Russia's GM Alexandra Kosteniuk, current Women's World Chess Champion,
defeats tough Georgian IM Sopiko Khukhashvili to advance to R3.
Seven matches was decided on tie-breaks today. All of them were decided in rapid games. Katerina Lahno, Zhu Chen, Ruan Lufei, Aleksandra Kosteniuk, Elmira Skripchenko and Huang Qian confidentially won their matches with 2:0 and joined the participants who had already promoted. Viktorija Cmilyte who made a draw in the first game against Elisabeth Paehtz succeeded to win in the second game. The most remarkable defeat was caused by Huang Qian who kicked the former world champion Antoaneta Stefanova out of the tournament. In the first game Huang Qian got position with advantage from the opening and converted it into a point. In the second one Bulgarian player had a comfortable position and chances to equalize a score in the match but didn't succeed.

Former Women's World Chess Champion, Bulgarian GM Antoaneta
Stefanova, loses R2 playoffs to China's WGM Huang, Qian and
is out of the Championship - a shocker.

I've been to the Crowne Plaza Hotel.  I can't speak to the room quality because I did not stay in a room,  but the other ameneties that I saw (while playing in the Hales Corners Chess Challenge XIII in September) are very nice, although they could use a larger "general store" --.  The hotel is conveniently located to the airport and expressway, as well as main Milwaukee roadways.  Nice restaurant and the staff was very accomodating to getting us in and out on time to start our afternoon Game 3 at 1:30 p.m. (we started lunch late). 

Wisconsin Chess Academy has a new website and it has little information on it.  I looked in vain tonight  for a list of teams coming to play in the Pan Am Intercollegiate but since Susan Polgar posted she would be in Milwaukee on the dates, I assume Texas Tech's Team will be competing and GM Polgar will be here with her team. 

The last time the Pan American Intercollegiate Team Chess Championships was held in Milwaukee, Wisconsin was 2000. With the Texas Tech Team making tremendous strides in just a few years, since the founding of SPICE (Susan Polgar Institute for Chess Excellence), perhaps this year will be the year UTD will lose it's Pan American crown.

China's Publicity Stunt Backfires

China stood up by winner of 'Confucius peace prize'
By Michael Martina Michael Martina – Thu Dec 9, 6:00 am ET

That grimace on the unidentified little girl is supposed
to be a smile!  She was obviously chosen to evoke
an "awwwww, ain's she cute" reaction.  Yes, she
is very cute.  No, your stupid "Prize" didn't work.
BEIJING (Reuters) – It was meant to be China's answer to the Nobel Peace Prize, a timely riposte to the honoring of jailed dissident Liu Xiaobo. But the winner of the first "Confucius Peace Prize" didn't even bother to show up.

Instead, it was left to a scared-looking girl, whom organizers did not properly identify, to collect a stack of bills for the $15,000 cash prize meant for former Taiwan vice-president Lien Chan.

Lien had won the prize for his efforts to improve relations between China and Taiwan, the self-ruled island Beijing claims as its own, beating out five other nominees, including past Nobel Peace Prize winners Mahmoud Abbas and Nelson Mandela.

"We believe that Mr. Lien Chan, with his knowledge, dignity, and political wisdom, would not refuse peace, and he would not refuse this prize," Confucius Prize organizer Tan Changliu gamely told a packed news conference in Beijing.

Lien, now honorary chairman of Taiwan's ruling Nationalist or KMT party, has not commented publicly on the prize.

Lai Shin-yuan, chairwoman of Taiwan's Mainland Affairs Council, told Taiwan lawmakers that the island's government found the prize "amusing."

"As far as we know it is an unofficial prize. We don't plan to make any comment on it," she said. "But we do find it amusing." [I'll bet you do, LOL!]

R2, Game 2: Yelena Dembo holds Tatiana Kosintseva to a draw,
eliminating her from the Championship after a G1 loss!
The second day was really horrible for Russian participants – 5 out 6 players were eliminated and only Aleksandra Kosteniuk continues to play tomorrow with Sopiko Khukhashvili on the tie-break. Among the promoted players are Humpy Koneru, Hou Yifan, Dembo Yelena, Anna and Maria Muzichyk, Harika Dronavalli, Ju Wenjun, Zhao Xue, Anna Zatonskih. Seven matches will be decided on tie-breaks tomorrow. After unfortunate start of the 2nd round Viktorija Cmilyte and Huang Qian won their games and equalized the score in the matches against Elisabeth Paehtz and Antoanetta Stefanova accordingly. Playing with black pieces Tatiana Kosintseva had to win today against Yelena Dembo after the unlucky first game. She was really close to succeed but lost the chance to activate her pieces under the time trouble and had to accept a draw.

Puzzles Aplenty

From The New York Times:

Essay
A Puzzle Solver Moves On to Life’s Riddles
By THOMAS LIN
Published: December 6, 2010

I confess: I used to be a puzzle addict.

I was corrupted at an early age. My physicist mom loved mind games of every kind. She fed me math riddles as if they were vitamins for the brain. She could finish a Rubik’s cube in the time it took me to do one side. Mind-(and material-)bending doodads littered the kitchen counter like so many odd, inviting garnishes. One contraption had wooden rings on a tether. Another required a series of transformations to extricate a small grooved hunk of steel from a larger hollow one.

Enigma: Asking the Mind to Jump Through Hoops

I had just put another spoonful of succulent sweet potatoes, slow-simmered with apples and pecans, onto my plate.

"I’ve been invited,” I said to the guests at the holiday dinner, “to write about puzzles.” (My memory of this dialogue may be blurred by carbohydrates.)

“But I’ve never found puzzles attractive,” I went on. “Why would you deliberately expose yourself to stress and frustration? You put in effort that you could have used to write a novel or cure cancer, and you come out with nothing but the solution to a previously solved problem. What’s the point? Why torment yourself?”

Ancient Egyptian Mathematicians Flexed Their Muscles with Puzzles

From The New York Times
Math Puzzles’ Oldest Ancestors Took Form on Egyptian Papyrus
By PAM BELLUCK
Published: December 6, 2010

“As I was going to St. Ives I met a man with seven wives. ...”

You may know this singsong quiz,

But what you might not know is this:

That it began with ancient Egypt’s

Early math-filled manuscripts. 
The Rhind Papyrus, more than 3,600 years old
 It’s true. That very British-sounding St. Ives conundrum (the one where the seven wives each have seven sacks containing seven cats who each have seven kits, and you have to figure out how many are going to St. Ives) has a decidedly archaic antecedent.

An Egyptian document more than 3,600 years old, the Rhind Mathematical Papyrus, contains a puzzle of sevens that bears an uncanny likeness to the St. Ives riddle. It has mice and barley, not wives and sacks, but the gist is similar. Seven houses have seven cats that each eat seven mice that each eat seven grains of barley. Each barley grain would have produced seven hekat of grain. (A hekat was a unit of volume, roughly 1.3 gallons.)

The goal: to determine how many things are described. The answer: 19,607.

The Rhind papyrus, which dates to 1650 B.C., is one of several precocious papyri and other artifacts displaying Egyptian mathematical ingenuity. There is the Moscow Mathematical Papyrus (held at the Pushkin State Museum of Fine Arts in Moscow), the Egyptian Mathematical Leather Roll (which along with the Rhind papyrus is housed at the British Museum) and the Akhmim Wooden Tablets (at the Museum of Egyptian Antiquities in Cairo).

They include methods of measuring a ship’s mast and rudder, calculating the volume of cylinders and truncated pyramids, dividing grain quantities into fractions and verifying how much bread to exchange for beer. They even compute a circle’s area using an early approximation of pi. (They use 256/81, about 3.16, instead of pi’s value of 3.14159....)

It all goes to show that making puzzles is “the most ancient of all instincts,” said Marcel Danesi, a puzzle expert and anthropology professor at the University of Toronto, who calls documents like the Rhind papyrus “the first puzzle books in history.”

Dr. Danesi says people of all eras and cultures gravitate toward puzzles because puzzles have solutions.

“Other philosophical puzzles of life do not,” he continued. “When you do get it you go, ‘Aha, there it is, damn it,’ and it gives you some relief.”

But the Egyptian puzzles were not just recreational diversions seeking the comforting illusion of competence. They were serious about their mission. In the Rhind papyrus, its scribe, known as Ahmes, introduces the roughly 85 problems by saying that he is presenting the “correct method of reckoning, for grasping the meaning of things and knowing everything that is, obscurities and all secrets.”

And the documents were practical guides to navigating a maturing civilization and an expanding economy.

“Egypt was going from a centralized, structured world to partially being decentralized,” said Milo Gardner, an amateur decoder of Egyptian mathematical texts who has written extensively about them. “They had an economic system that was run by absentee landowners and paid people in units of grain, and in order to make it fair had to have exact weights and measures. They were trying to figure out a way to evenly divide the hekat so they could use it as a unit of currency.”

So the Akhmim tablets, nearly 4,000 years old, contain lists of servants’ names, along with a series of computations concerning how a hekat of grain can be divided by 3, 7, 10, 11 and 13.

The Egyptian Mathematical Leather Roll, also from about 1650 B.C., is generally considered a kind of practice test for students to learn how to convert fractions into sums of other fractions.

The Rhind papyrus contains geometry problems that compute the slopes of pyramids and the volume of various-shaped granaries. And the Moscow papyrus, from about 1850 B.C., has about 25 problems, including ways to measure ships’ parts and find the surface area of a hemisphere and the area of triangles. Especially interesting are problems that calculate how efficient a laborer was by how many logs he carried or how many sandals he could make and decorate. Or the problems that involve a pefsu, a unit measuring the strength or weakness of beer or bread based on how much grain is used to make it.

One problem calculates whether it’s right to exchange 100 loaves of 20-pefsu bread for 10 jugs of 4-pefsu malt-date beer. After a series of steps, the papyrus proclaims, according to one translation: “Behold! The beer quantity is found to be correct.”

The problems in these ancient texts are not difficult by modern mathematical standards. The challenge for scholars has come in deciphering what the problems are saying and checking their accuracy. Some of the numerical equivalents are written in a symbolic system called the Eye of Horus, based on a drawing representing the eye of the sky god Horus, depicted as a falcon. Sections of the falcon’s eye are used to represent fractions: one-half, one-quarter and so on, up to one sixty-fourth.

Scholars have found a few errors in the problems, and Ahmes even wrote an incorrect number in his St. Ives problem. But over all, the equations are considered remarkably accurate.

“The practical answers are solved,” Mr. Gardner said. “What is unsolved about them is the actual thinking in the scribe’s head. We don’t know exactly how he thought of it.”

Chinese Expedition to Kenya Hopes to Recover the Past - Suitably Edited

From The Wall Street Journal online:

DECEMBER 4, 2010
Recovering China's Past on Kenya's Coast
By Virginia Postrel

A team of Chinese archeologists arrived in Kenya last week, headed for waters surrounding the Lamu archipelago on the country's northern coast. They hadn't made the trip to study local history. They came to recover a lost Chinese past.

In the early 1400s, nearly a century before Vasco da Gama reached eastern Africa, Chinese records say that the great admiral Zheng He took his vast fleet of treasure ships as far as Kenya's northern Swahili coast. Zheng visited the Sultan of Malindi, the most powerful local ruler, and brought back exotic gifts, including a giraffe. "Africa was China's El Dorado—the land of rare and precious things, mysterious and unfathomable," writes Louise Levathes in her 1994 history of Zheng's voyages, "When China Ruled the Seas."

Now the Chinese government is funding a three-year, $3 million project, in cooperation with the National Museums of Kenya, to find and analyze evidence of Zheng's visits. The underwater search for shipwrecks follows a dig last summer in the village of Mambrui that unearthed a rare coin carried only by emissaries of the Chinese emperor, as well as a large fragment of a green-glazed porcelain bowl whose fine workmanship befits an imperial envoy. Although Ming-era porcelains are nothing new in Mambrui—Chinese porcelains fill the local museum and decorate a centuries-old tomb—the latest finds suggest that the wares came not through Arab merchants but directly from China.

For a resurgent China with often-controversial business ventures in Africa, Zheng's voyages epitomize what the 20th-century literary critic Van Wyck Brooks called a "usable past"—a historical tradition that serves present needs. Falling somewhere between history and myth, a usable past selects and emphasizes what is relevant and resonant for the present and omits the contradictory or distracting. It both shapes and communicates identity, whether national, ethnic, artistic, religious, institutional or personal.
