Concrete Used in Pyramids


T.W. Schultz used to emphasize that the level of technology in an economy depended more on the incentives and institutions for adoption and diffusion, and less on the invention of the technology, which he thought was a shorter hurdle than usually thought.  The Antikythera Mechanism is one historical technology that dramatically supports Schultz’s view.  If it survives scrutiny, the following article would provide an additional example supporting Schultz. 


(p. A18) Reporting the results of his study, Michel W. Barsoum, a professor of materials engineering at Drexel University in Philadelphia, concluded that the use of limestone concrete could explain in part how the Egyptians were able to complete such massive monuments, beginning around 2550 B.C. They used concrete blocks, he said, on the outer and inner casings and probably on the upper levels, where it would have been difficult to hoist carved stone.

”The sophistication and endurance of this ancient concrete technology is simply astounding,” Dr. Barsoum wrote in a report in the December issue of The Journal of the American Ceramic Society.

Dr. Barsoum and his co-workers, Adrish Ganguly of Drexel and Gilles Hug of the National Center for Scientific Research in France, analyzed the mineralogy of samples from several parts of the Khufu pyramid, and said they found mineral ratios that did not exist in any known limestone sources. From the geochemical mix of lime, sand and clay, they concluded, ”the simplest explanation” is that it was cast concrete.

Self-Proclaimed Advocate for Poor, Gets Two $400 Haircuts: Looking Good in Council Bluffs

John Edwards, the North Carolina Democrat, announced on Thursday that he was reimbursing his campaign $800 to cover what his aides said was the cost of two haircuts — yes, you read that correctly — by a Beverly Hills barber, though, perhaps, the word stylist is more applicable.

. . .  

Mr. Edwards has presented himself in the Democratic field as an advocate of working-class Americans, lamenting the nation’s growing economic disparity.

Mr. Edwards was disparaged as “the Breck Girl” by Republicans when he ran for president in 2004. More recently, he was captured on camera, waiting for an interview to begin and presumably unaware that he was being taped, fussing with his hair for nearly two minutes.

That clip found its way to You Tube, with the song “I Feel Pretty” playing in the background. Posted on Nov. 8, 2006, it was viewed 289,288 times as of Thursday evening.

The Case Against Gun Control

 

   Venus Ramey shows how she balanced her pistol on her walker to shoot out the tires of an intruder on her farm.  Source of photo:  screen capture from CNN clip "Granny’s Packing Heat" as viewed on 4/23/07.

 

In the wake of the Virginia Tech killings, there have been some renewed calls for more gun control (see the WSJ and NYT articles cited way below).  But we should not forget that a gun can also be a leveler; it gives the ordinary citizen a fighting chance against the thief and the murderer.

There was a great scene in the first Indiana Jones movie (Indiana Jones and the Temple of Doom, 1984) where Indy is being chased by a huge bad guy armed with swords.  The crowd clears, and the the huge man confidently and ominously twirls his swords.  Indy looks at him quizzically for a couple of seconds, pulls out a pistol, and shoots him. 

When I first saw that scene, the theater erupted in laughter and applause.

Laughter and applause are also appropriate responses to the story of 82 year old, former Miss America, Venus Ramey: 

 

Miss America 1944 has a talent that likely has never appeared on a beauty pageant stage: She fired a handgun to shoot out a vehicle’s tires and stop an intruder. Venus Ramey, 82, confronted a man on her farm in south-central Kentucky last week after she saw her dog run into a storage building where thieves had previously made off with old farm equipment.

Ramey said the man told her he would leave. "I said, ‘Oh, no you won’t,’ and I shot their tires so they couldn’t leave," Ramey said.

She had to balance on her walker as she pulled out a snub-nosed .38-caliber handgun.

"I didn’t even think twice. I just went and did it," she said. "If they’d even dared come close to me, they’d be 6 feet under by now."

“Solitude Serves as a Refreshing Balm”

The WSJ summarizes an April 2007 Psychology Today article.  The study that is discussed sounds relevant to the one-sided push for more collaboration and team production in business, and co-authorship in academics.  The benefits of collaboration should not blind us to the costs.

 

Amanda Guyer, a psychologist at the U.S. National Institutes of Health in Bethesda, Md., has found that individuals who withdraw from other people’s company are more sensitive than extroverts to a wide range of positive emotional cues. Situations rife with emotional triggers, such as parties, can be wearying for such people, while solitude serves as a refreshing balm.

Castro’s Legacy of “Death, Tears and Blood”

Like thousands of other Cubans, I was arrested in the middle of the night. Fidel Castro’s police raided my parents’ home, stuck a machine gun in my face and took me away. It was 1960 and I was 22 years old.

The news that the Cuban dictator is gravely ill floods my mind with memories of my years spent in captivity. I believe that those of us who were political prisoners know his legacy better than anyone. For 22 years, I was an inmate in his vast prison system, mostly confined to an island gulag, for crimes I did not commit.

. . .

The legacy of Castro for Cuba will be much like that of Stalin in Russia, Pol Pot and Ieng Sari in Cambodia and Hitler in Germany. It will be the memories of the unknown numbers of victims, of concentration camps, torture, murder, exile, families torn apart, death, tears and blood. Castro will go down in history as one of the cruelest of all dictators — a man who tormented his own people.

But his poisonous legacy will also include the double standard by foreign governments, intellectuals and journalists who fought ferociously against the unspeakable violations of human rights by right-wing dictatorships, yet applauded Castro. To this day many of these intellectuals serve as apologists and accomplices in the subjugation of the Cuban people. Rafael Correa, the recently inaugurated president of Ecuador, has declared that in Cuba there is no dictatorship. Evo Morales, president of Bolivia, considers Castro his mentor and has already shown that he is willing to silence his own critics at the point of a gun. Venezuela, once a democracy, is the new Cuba, replete with a growing population of political prisoners.

Obama Should Support School Vouchers Experiment

 

There’s something about our nation’s capital that converts many leading Democrats to school choice. Perhaps it’s the glimpse that Washington, D.C. affords into inner-city public schools.

But in most cases this appreciation of school choice extends only to their own children — and not to the millions of children in failing public schools. Indeed, a nearly perfect correlation exists among Democratic presidential candidates who have exercised school choice for their own children and those who would deny such choices to the parents of other children.

. . .

The mystery man is Sen. Barack Obama, who sends his child to a private school in Chicago yet once referred to school vouchers as "social Darwinism." Still, he says that on education reform, "I think a good place to start would be for both Democrats and Republicans to say . . . we are willing to experiment and invest in anything that works."

Well, school choice works. Every study that compares children who applied for school choice scholarships and received them with those who applied but did not shows improved academic performance. More important, every study that has examined the effect of school choice competition has found significantly improved performance by public schools.

Given their track records it is doubtful how many candidates will agree with Sen. Obama’s professed openness to experiment. But as he might say, we can always have the audacity to hope.

Advice from Charles Koch: A Successful Business Schumpeterian

   Source of book image:  http://media.wiley.com/product_data/coverImage300/89/04701398/0470139889.jpg

 

When Charles Koch became the chief executive of Rock Island Oil & Refining after the death of his father in 1967, the company was a moderately successful enterprise based in Wichita, Kan. He renamed it Koch Industries in honor of his father — and over the next 40 years proceeded to transform Fred Koch’s legacy into the world’s largest private company. Koch Industries — now a commodity and financial conglomerate that includes brands such as Stainmaster, Lycra and Dixie cups — has 80,000 employees in 60 countries. Its revenue last year was $90 billion. In one generation, the book value of Koch Industries has increased 2,000-fold. That’s an 18% compounded annual return — comparable with the long-term track record of Warren Buffett’s Berkshire Hathaway.

. . .

At age 71, Mr. Koch clearly feels that the time has come to pass along the business formula that has served him so well. In "The Science of Success," he describes a technique, called Market-Based Management (MBM), that he says evolved from his reading, early in his career, in history, political science, economics and other disciplines. He arrived at an understanding of what allows a free society to prosper, Mr. Koch says, and decided to apply those principles to business.

. . .

. . .   He is especially fond of the "Austrian school" of economists, such as Ludwig von Mises and Joseph Schumpeter, who emphasized production processes, technology and the dynamic competitive models of "creative destruction."

Another Effort to Explore the Black-Box of Innovation

 

(p. 210)  Schumpeter argues that innovation can happen endogenously and that its main source is the creative entrepreneur.  Schumpeterian innovation is still black-boxed, however, because it is the product of the ingenuity of entrepreneurs and cannot be reproduced systematically.

. . .

The reconstructionist view takes off where the new growth theory left off.  Building on the new growth theory, the reconstructionist view suggests how knowledge and ideas are deployed in the process of creation to produce endogenous growth for the firm.  In particular, it proposes that such a process of creation can occur in any organization at any time by the cognitive reconstruction of existing data and market elements in a fundamentally new way.

Anti-Wal-Mart is Anti-Free-Choice

     Source of logo/header:  http://www.muddycup.com/mudlane/img/header.jpg

 

The article excerpted below reveals the soul of much of the anti-Wal-Mart movement.  It is not anti-big; it is anti-competition and anti-free-choice.

 

How in the world did a guy who started his first coffee shop on Staten Island six years ago and now runs five others in far-flung Hudson Valley towns become the moral equivalent of Wal-Mart and Starbucks? “Well, it’s now official,” he announced last month on the Web site that promotes his Muddy Cup coffeehouses. “I am now head of the evil empire.”

. . .

And now the talk of New Paltz has to do with something far more important than mere marriage — coffee. More specifically it’s whether Mr. Svetz is plotting an act of entrepreneurial imperialism by presuming to open one of his Muddy Cup coffeehouses next door to the ultimate green icon in town, the funky 60 Main coffee shop operated in conjunction with the nonprofit New Paltz Cultural Collective.

. . .

Little did he know. As word filtered out he began receiving a blizzard of e-mail messages from 60 Main proponents, reacting to an urgent appeal from the collective. The messages threatened a boycott and told him to stay home. “If we can stop Wal-Mart we can stop you,” said one.

“We do not want to become yet another small town taken over by huge corporations,” read another.

. . .

Mr. Svetz is still stunned by the whole thing, particularly his sudden status as a giant corporation. He says that just as lots of bars coexist in town, several coffee shops can too. Maybe he’s right. Maybe he’s not. He’s not Wal-Mart, but maybe it’s fair to ask how many artist-friendly coffeehouses the village can support. But it’s hard to argue when he says that even in New Paltz, businesses generally have to compete to survive, not find a way to build a Berlin Wall around town.

“When a community starts building walls and saying you don’t belong here or you don’t think like we do, that can’t be a good thing,” he said.

Leapfrog the Elevator Competition into a Blue Ocean

 

(p. 178)  They wanted to cut waste, freeing people to produce higher-quality elevators faster at lower cost to leapfrog the competition.  But plant employees could not have known that.
