Smoke

Dear Chinese government:

According to the following statistics, 50% of Chinese men smoke, consuming one-third of the world’s cigarettes.

As you can imagine, this is a significant drag-down of the Chinese national power, given the well known facts about health hazards caused by smoking.

Please put your authoritarian power in good use and ban smoking outright. No, not just in public places, but illegalize cigarettes all together.
Unlike the dysfunctional democracies like America who have to listen to tobacco lobbyists, you have no such baggage. And I am pretty sure no Chinese tobacco kingpin is more powerful than Bo Xilai, whom you sacked with such ease and grace just last week.

You can easily bankrupt the world’s tobacco industry by eliminating one-third of their revenues. This will go down as one of the major achievements in human history.

The last dynasty, Qing, in a much weaker state, had the gut to ban opium. I am pretty sure China is strong enough now to win a second opium war even if some foreign imperial power is stupid enough to start one.

Sincerely yours.

Death

Humans seem to have so much trouble accepting the nature of death that they need to come up with all kinds of alternatives like after-life and reincarnation.

Artificial intelligence

When I was younger I preferred to stay away from people as much as possible, as most of them are not very interesting and it is much more rewarding for me to be alone thinking and reading.

When I get older, I realized that humans are intensively intriguing subjects for study. I started to spend a lot of time observing human behaviors and try guessing what they are thinking and predicting their actions.

This caused certain dilemma for me: on one hand I still want to be as far away as possible from people, but on the other hand, I want to be close enough with them for the purpose of studies and observations.
(The penalty and reward seem to go in tandem; crowd behavior is the most interesting, but also the most annoying to be part of.)

Fortunately, computer science comes into rescue. Far from the common stereotypes (of nerds locking in toilets), computer science, especially the most current and active subjects, are very human centric. One example is user interface, including design for better user experiences, as well as analysis and synthesis for deeper understanding and more advanced interactions.

A more recent example is social networking. Previously, most human daily activities simply dissipated into entropy. Now, with people spending more of their interactions through various social networking sites, we can record their activities in better quality and quantity.
Such data not only enables better computer technologies but more profoundly, more insights into human nature. (Facebook probably knows more about certain individuals than their mothers do.)

Two sci-fi series could provide inspirations for both directions.


Caprica is about how humans create Cylons, a cyber-genetic life form that eventually pushes humans near extinction in the main Battlestar Galactica series (which I found to be much less interesting).


Dollhouse is about how technologies can allow memories and personalities to be extracted from one individual and installed into another, essentially programming human brains.

Both offer insights into computer science and humanity, as well as highly enjoyable entertainments. Unfortunately, both got canceled prematurely due to low ratings, a confirmation of my childhood observation about how ordinary humans would react to deeper materials.

Nightmare

The following scenario happened in one of my dreams early this morning.


During the committee meeting of one major graphics conference, a paper of mine got discussed. So I need to wait outside the room. I noticed that a lot of other people also walked out, and I wondered what the heck that was about. Eventually, the paper chair also came out and announced that nobody can review my paper because every committee member was in conflict.

A very senior guy came over and said: I told you not to make too many friends!

In the end, the paper was marked as *not accepted* (a new category beyond rejected, accepted, and togged) due to *lack of committee members for reviewing*. My co-authors told me they hate me and accused me of being an academic polygamist.

Well, clearly, being a dream, this is not entirely logical, as if there were no committee members who could review a paper it would have been discovered during the paper sorting process, not the meeting itself.
But still, an interesting beginning for a day.

Scarcity

Imagine a world where all resources are unlimited. Everything has infinite supplies and free to access like air. Everyone can live forever without aging, disease, injuries, fears, or any forms of constraints.

What would it be like? Do you think it is heaven, or hell?

Life is worth living precisely because it is finite and every resource is limited.

A year of no significance

1587, a Year of No Significance (Chinese: 萬曆十五年) is a book by historian Ray Huang (Chinese: 黃仁宇) which described how a sequence of seemingly insignificant events precipitated the eventual downfall of the Ming dynasty, as well as China itself. I remember getting totally fascinated by this book as a high school kid. The book is not flawless, but it is fascinating in highlighting how significant long term trends, which usually happen slowly, are often preceded by very small signs.

It is like the famous Chinese proverb, 一葉知秋: from a falling tree leaf one can know that the autumn is coming.

If future historians are going to write a similar book about the eventual downfall of the America (dynasty) as well as the entire West, the analogous year will be 2001, or probably even a specific day, September 11. Contrast to 1587, this is a year of *major* significance. But THE event is no less precipitating than those in 1587.

I am looking forward to read this book, and I hope it will be as enthralling as the one by Ray Huang.

Thank you very much for providing all the motivations I need.

I am going to prove you wrong by outperforming whomever you think is better than me.

Life is a (serious) game, so play hard, be triumphant, and (most importantly) have fun. The game is very short and you might only play it once, so do not waste your time.

A tale of two brothers

A long time ago in a place far far away, a pair of twin brothers were born. Their parents worked long hours, so they were put with different day care families. One of them, nicknamed Rat, lived with his grandfather. The other one, nicknamed Dog, lived with a retired nanny.

The grandfather was a former college professor who had nobody around to lecture on, so he force-fed Rat everything he knew, like chess, history, and classics literature. The grandfather was also a retired army officer, so he instilled discipline and self-control into Rat’s mentality and life style. Through this rigorous training, Rat absorbed everything happily, even though some of the subjects were clearly beyond his age (e.g. classics which should be for high school, not kindergarten, kids). At first grade he knew that history books are filled with lies written by the winners, and at fourth grade he beat his grandfather in a chess match. He was so ahead of his classmates that he found school very boring and thus got into a lot of troubles. To channel his excessive energy, Rat tried to pick up college calculus at fifth grade, but did not succeed until he was 15. Because he derived so much pleasure and satisfaction through learning new subjects and outperforming his peers, Rat spent more and more of his time studying, which further enhanced his satisfaction and achievement. He was in such a virtuous cycle that he did not recall taking any day off including holidays and weekends.

The retired nanny was barely literate, so she did not teach Dog much useful. She got up late and spent most of her time watching TV, so Dog did not learn a disciplined life style. Dog was slightly behind his classmates when he started school, and found school work arduous and unrewarding. Thus, he did not spend a lot of time studying, which made him further behind, which in turn further discouraged him. It also did not help that his father constantly compared him to his twin brother. Dog was in such a vicious cycle that he never fully realized his potential, even though he is an identical twin to his brother.

This tale is mostly fictitious (Dog is entirely made up even though Rat is partially based on myself), but I want to use it to illustrate three very important scientific principles applied to education, especially during early childhood.

Initial condition
Physics taught us that even a tiny little difference in the initial conditions can lead to dramatic differences in the eventual outcomes. This is why early childhood education is so important. By nature, kids do not want to be disciplined, so parents will have to enforce that. This is one of the biggest differences between Chinese and American mentalities for education, and for this, I am totally on the Chinese side. I would not have been what I am today if it were not for the rigorous training I received from my family when I was a little kid.

Compound interest
This is probably the most powerful concept in math and finance. Intelligence and confidence are accumulated in an exponential rather than a linear rate, due to the self feedback loop. Even a tiny difference in how hard you study everyday can lead to huge differences in the long run. I remember seeing a study showing the magic of merely studying one hour more per day. In my personal case, I did not take holidays or weekends off, and that is an automatic 40 percent more work than ordinary folks! I do not even have to be particularly smart or talented to outperform them.

Anchoring effect
This is one of the most well known effects in psychology. People judge things in a relative instead of absolutely scale (e.g. they are happier to receive 20 dollars if everyone else receives only 10 than to receive 40 dollars if everyone else receives 80). In the story above, Dog has absolutely the capability to be like his twin brother, but was frustrated by being compared/anchored relative to Rat and his classmates.

And of course, if the three principles are combined together their total effects would be even more significant.

In summary, if you really care for your children, give them tough love: instill discipline from early childhood, ask them to work as hard as they can in a daily basis, and try to encourage instead of frustrate them through proper peer comparison (e.g. identifying an aspect that the kids performs well relative to others and use that as an motivation). I do not have any kids now, but if I do that would be how I am going to bring them up.
