Book Review: The Next 100 Years: A Forecast for the 21st Century


With the advantage of writing this review 10% into the 21st century, I can point out the important factors that Friedman has missed in this book.

Friedman does not show an understanding of the Chinese culture which is rising rapidly and hence has misjudged the implication of a powerful China. He is absolutely correct that China was more like an isolated island, with difficult to penetrate borders on all sides. That is no longer true in light of modern technology. In 1421, before Columbus set sail to 'discover' the world, Chinese fleet, led by ZhengHe has already visited Middle East and Eastern Africa. The size of the ocean going junks used by ZhengHe built over 60 years earlier towered over Columbus ships. [see http://www.youtube.com/watch?v=FI1AmTa-bV0] Until about 500 years ago, China was the world's leading economy and power.

China has been conquered by foreign powers twice in her entire history. First at Yuan Dynasty which lasted less that 100 years and the second time at Qing Dynasty [1644-1911 CE] - the last dynasty before the new China was born. The result is that the conquerors were melted into the Chinese culture and became Chinese.

The above two snippets of history tell a story which Friedman has completely missed.

1. Being geographically isolated in the past, China has to be self-sufficient in order to survive. China could not depend on conquering other people to steal wealth. For an agricultural society to remain viable, a stable society was a prerequisite. As such, Chinese is a peace loving culture. When she has the power to conquer the world, she chose not to do so.
2. Being self sufficient, it was tempting for the Emperors to close the border and focused mainly on internal affairs. Of course the closing of trade in the last 500 years proved to be disastrous for China. Chinese, thus, has learnt a lesson which is still painfully remembered. A country needs a sufficient strong defense in order to protect herself. That's the main motivation why Mao insisted on China becoming a nuclear nation.

In Outliers: The Story of Success, Gladwell described a difference between rice culture and wheat culture. The southern China is a rice culture and that hard working moral has permeated throughout China. The discipline and efficiency of achievement as demonstrated by the 2008 Olympics, for instance, reflects the collective will of the Chinese people.

Can China continue to develop her economy? Friedman did not think so. I think that is his first mistake. Yes, dynasties came and gone. But China has remained as a unity. As Kissinger, correctly observed, China is more a culture than a nation state. It will not fragment as Friedman suggested.

Chinese economy started at a very low level. Until her per capital income is in par with leading economy, her economic growth is easy. She does not need to make mistakes which are typical at the "cutting edge". When Chinese per capital income is in par with USA, her economy would be 4 times larger than USA - just by size of the population. Recent global financial crisis indicates that USA economic strength is not at powerful as Friedman would have wished.

With a powerful peace loving nation in place, the world would be safer. Unless some leaders in a country are insane, waging war against a nuclear nation is MAD. There has been no world war since the invention of nuclear weapons speaks volume to the danger of major conflict. USA's navy power could not be used to force her will onto China, nor be used to limit Chinese economic grow.

Just by the size of the population, China is producing more PhDs in Science and engineering than USA. A report in 2002 predicts that by 2010, China will have more PhD graduating than USA. [source: http://english.peopledaily.com.cn/200210/21/eng20021021_105393.shtml] The consistent relatively poor performance of USA students in all educational measures points to a weakening intellectual capacity of USA. The best students in USA choose to study the soft easy subjects such as commerce and law. The best students in China choose to study the hard sciences. The intellectual strength of China will only increase while the same cannot be said to USA. The limiting factor to Chinese growth is resources and energy. The lower living standard in China means Chinese manufacturing can afford to pay more for the scarce resources than USA. In a world where military might could not be used to steal other nations' resources, China will compete on economic terms with USA for energy and resources.

China is the largest foreign creditor of the USA government. Chinese strategic dumping of USA Treasury bonds into the market can influence the interest rate at which USA government can borrow money. If there is any leverage a government can put on another, it would be China having an upper hand than the USA.

21st century will not be an easy century. The climate change will have significant impact on relationships between nations. Friedman has completely ignored this factor in this book. The world has already warmed by 0.8 deg C and there is a 1.6 deg C locked in even if by a miracle every country on this planet wake up tomorrow morning and take the most serious steps to fight climate change - which is not likely to happen. There will be large population displacement and serious "natural" disasters due to the effect of extreme climate. Economic resources will be stretched.

The declining of fossil fuel will also significantly affect the economic development. China has put renewable energy source as her main strategic goal and determined to be the leading manufacturer of renewable energy. Independence of fossil fuel has been a national agenda since President Carter. The domestic politics of USA has been delaying any action in reducing USA's dependence on oil. That's not a sign of a power nation.

From history point, USA is young, very young. In the wild, death at young age is not uncommon. Being young does not imply powerful.

If USA policy is informed by Friedman, she will be in very dangerous water. USA needs to learn from UK how to survive in a world dominated by power other than USA.

Book Review: Take Five!


I got a pre-release reviewer copy of Kaye Hagler's Take Five! from LibraryThing

First a couple of comments then I will describe the good points of the book.

1. The author started with

During my twenty plus years as a teacher in elementary, middle, and high school classrooms, I have tried almost every bell-ringer on the market. After all, the bell-ringer serves as a valuable classroom management tool for those crucial (and all-too-often chaotic) minutes at the beginning of the class period.

After I read the book, I still do not know what and how bell-ringer are supposed to be used in a classroom. I suppose that would be a technique common in USA classrooms. When I did a google search, I cannot find any information as well. If someone can explain that to me, I will be grateful.

2. There is a section called "A Little Learning Theory" in which the author listed a few educator such as John Dewey, Joanne Hendrick and focussed on their criticism of learning. However, this little section tells us nothing about the theories. I suppose readers would be familiar with these names - then what is the point of including such a section. However, for this book, this is OK because this book is not an education theory book. This is a teacher resource book!


So what is this book?

After I went through the first 10 pages, there are the meat of the book. An alphabetical list of 182 "prompts". Here is one example:

Paper or Plastics? 2
Plastic doesn’t seem to be going away, at least not today! How would life be different if plastic had never been invented? For example, there wouldn’t be AstroTurf for teams who play in covered stadiums or disposable silverware.

Without plastic, there would be more broken glass from bottles, meaning more cut fingers—and yet no Band-Aids to cover them. In fact, if you were to look around right now, you would see numerous items made of plastic: pencil sharpeners, pens, contact lenses, crates and shelving, clocks, table surfaces and chairs, computers, televisions . . . the list goes on and on.
Now it’s your turn. Brainstorm to list the many ways life would be different without the invention of plastic.

*W.A.L.L. (Write A Language Link) is a folder on students' computers which the teacher can read and comment. Kind of like the wall in facebook.

If you are a language teacher, there are 182 ready-to-use templates which the author called "prompts" for immediate application or modification. "100-plus extensions lessons are also provided through the Teacher Tips."

It is good to see thinking skills being incorporated into any lesson. The fact that such skills can be learnt via fun and collaboration is the greatest strength of this book. However, the collaboration part, which is at the core of my own teaching, may improve slightly by adding a "debriefing" part to each and every activity. There is no mention of "debriefing" in the book (I did a search on "debrief" in the reviewer pdf of the book and found no reference to it). Debrief is the process of reinforcing the learning. When students can articulate what they have learnt - especially in thinking skills - in front of the peers, such a process also serves the purpose of spreading the thinking skills to other members of the class.

As a teacher resource for language teacher, I would give this book 4.5 stars out of 5.

Was Linda Katechi sincere?



As the Chancellor of a University, was she naive enough to believe that police would not use inappropriate force? If yes, she did not deserve to be the Chancellor. If no, she did not deserve to be the Chancellor.

Hindsight is always prefect. But the moral call, which is the critical attribute of a leader, is not to commit wrong so that hindsight would be unnecessary. That's the leadership. Has Lida Katechi demonstrated sufficient leadership to remain as the chancellor of any university?



As the police retreat, was it clear who were on the moral high ground? The cowardice of the police was in plain sight. When it was a few students, they used excessive brutality. When they were out-numbered, they just retreated and could not stand up for what they were supposed to do in the first place.

7inch tablet

I wrote earlier the availability of a low cost 7inch tablet from India. Recent research indicates that it is NOT the cheapest 7inch tablet - China and Taiwan were able to produce better specification 7inch tablet at lower cost than India. A report from AsianCorrespondent claimed the Aakash (the Indian 7inch low cost tablet) is DOA - dead on arrival, just like Indian's low cost car - Tata' Nano.

Logical fallacy

I was sent an email containing the following statements. Politics aside, I like to comment on the logical fallacy committed by the sender.

Statement:

If any other of our presidents had doubled the National Debt, which had taken more than two centuries to accumulate, in one year, would You have Approved?

If any other of our presidents had then proposed to Double the debt again within 10 years, would you have approved?
Fallacy: Judging an action which asking the cause of the action. What else can Obama do when he inherited a situation that bad?

Statement:
If any other of our presidents had criticized a State Law that he admitted he never even read, would you think that he is just an ignorant hot Head?
Fallacy: How does one know if another person has or has not read something? "that he admitted he never even read" - What is the context when this admission was made?

Statement:
If any other of our presidents had pronounced the Marine Corps as if it were the Marine Corpse, would you think him an Idiot?
Fallacy: Diversion. What has the pronunciation have to do with an argument?

Statement:
If any other of our presidents had put 87,000 workers out of work by arbitrarily placing a moratorium on offshore oil drilling on companies that have one of the best safety records of any industry because one foreign company had an accident, would you have agreed?
Fallacy: Almost every policy will have winners and losers.

Statement:
If any other of our presidents had used a forged document as the basis of the moratorium that would render 87000 American workers unemployed,
would you support him?
Fallacy: "forged document" - proof needed. BTW, was it not that USA invaded Iraq based on false premise - the Iraq has weapon of mass destruction?

Statement:
If any other of our presidents had been the first President to need a teleprompter installed to be able to get through a press conference, would you have laughed and said this is more proof of how inept he is on his own and is really controlled by smarter men behind the scenes?
Fallacy: Good point. Just watch the following video.

Free energy

A basic principle in Physics, at least in the realm of our everyday size, energy is conserved. That means that perpetual machine is an impossibility. However, here are two videos on youTube which claims to produce free energy with over millions of views.



Power is not just voltage. Power is voltage times current. By increasing the number of turns in the rotor, we can get a higher induced e.m.f, ie voltage. But once a load is applied, there will be a current and the current will generate a force to oppose the motion and hence stopping the rotor. So far, no one has just demonstrably show a perpetual machine, not to mention extracting additional energy out of the machine.

Why are the most complex organisms on this planet reproduce sexually?

As we move into the era of ideas, we can copy evolution and let ideas to have sex.


The answer is the exchange of ideas. The ability to combine and recombine ideas.
