Re: Syria and the Middle East
The Islamists and radicals are taking over the country.
It is reported that many intellectuals - many of whom
were in the Arab Spring front line hoping for democracy -
are very discouraged and wanting to emigrate to
the US and other countries. Unfortunately, the news from
Syria is not all good. The Arab unrest there may unleash
a theocratic tyranny/dictatorship worse than Bashar al-Assad.
US/France/GB is turning their back on someone whom
they've been courting for years. At the same time, Russia
is drawing a line in the sand against the West by continuing
supporting al-Assad. Iran is arming to the teeth including
possible nuclear weapon development,
playing chicken with our Navy and threatens the
Strait of Hormuz.
It'll be a rough ride for all of us...

On reading Epicurus
"Don’t fear god,
Don’t worry about death;
What is good is easy to get, and
What is terrible is easy to endure."
Philodemus, Greek Epicurean philosopher
Epicureanism
Epicurus (341 BCE - 270 BCE) was an ancient Greek philosopher, raised on Samos then returned to Athens in 307 BCE to practice philosophy and developed a school of philosophy called Epicureanism. He lived very simply and frugally. In many letters throughout his life, he himself said that he was quite content with just water and simple bread and lots of friends and expressed his gratitude to his parents, kindness to his brothers, and gentle kindness to all around him.
He wrote that there is nothing fearful in the absence of life. So death, the most frightening of bad things, is nothing to us; since when we exist, death is not yet present, and when death is present, then we do not exist. Therefore, it is relevant neither to the living nor to the dead, since it does not affect the former, and the latter do not exist. Epicurus wrote that "... a wise man neither rejects life nor fears death. For living does not offend him, nor does he believe not living to be something bad. And just as he does not unconditionally choose the largest amount of food but the most pleasant food, so he savors not the longest time but the most pleasant."
Epicurus, by his personal example and by his teaching and a lifetime of serenity and wisdom, revealed the path to redemption from unhappiness. He was revered by his followers as a divine sage who had answers to all the important questions of life. What attracted converts was the prospect of personal happiness, for which Epicurus offered clear philosophical advice. The fundamental obstacle to happiness, says Epicurus, is anxiety. No matter how rich or famous you are, you won’t be happy if you’re anxious to be richer or more famous. No matter how good your health is, you won’t be happy if you’re anxious about getting sick. You can’t be happy in this life if you’re worried about the next life. You can’t be happy as a human being if you’re worried about being punished or victimized by powerful divine beings. But you can be happy if you believe in the four basic truths of Epicureanism: there are no divine beings which threaten us; there is no next life; what we actually need is easy to get; what makes us suffer is easy to put up with.
Illness and pain are disagreeable, but nature has so constituted us that we need not suffer very much from them. Sickness is either brief or chronic, and either mild or intense, but discomfort that is both chronic and intense is very unusual; so there is no need to be concerned about the prospect of suffering. Know the limits of what you need, recognize the limits of what your body is likely to suffer, and enjoy the confidence that your life will be overwhelmingly pleasant, unless you poison it with anxiety. “Don’t worry about death.” While you are alive, you don’t have to deal with being dead, but when you are dead you don’t have to deal with it either, because you aren’t there to deal with it. “Death is nothing to us,” as Epicurus puts it, for “when we exist, death is not yet present, and when death is present, then we do not exist.”
Worrying about death casts a general pall over the experience of living, either because people expect to exist after their deaths and are humbled and terrified into ingratiating themselves with the gods, who might well punish them for their misdeeds, or else because they are saddened and terrified by the prospect of not existing after their deaths. But there are no gods which threaten us, and, even if there were, we would not be there to be punished. Our souls are flimsy things which are dissipated when we die, and even if the stuff of which they were made were to survive intact, that would be nothing to us, because what matters to us is the continuity of our experience, which is severed by the parting of body and soul. It is not sensible to be afraid of ceasing to exist, since you already know what it is like not to exist; consider any time before your birth—was it disagreeable not to exist? And if there is nothing bad about not existing, then there is nothing bad for your friend when he ceases to exist, nor is there anything bad for you about being fated to cease to exist. It is a confusion to be worried by your mortality, and it is an ingratitude to resent the limitations of life, like some greedy dinner guest who expects an indefinite number of courses and refuses to leave the table.
“What’s good is easy to get.” We need food, water, shelter from the elements, and safety from hostile animals and people. All these things lie ready to hand and can be acquired with little effort or money. We don’t need extravagant foods, palaces, or bodyguards, which are expensive and difficult to acquire and keep. People who want more than they need are making a fundamental mistake, a mistake that reduces their chances of being satisfied and causes needless anxiety.
The discipline of Epicurean philosophy enables its followers to recognize how little they actually need, to enjoy possessing it, and to enjoy the confidence that they will continue to possess it. On the other hand, there is no reason not to enjoy occasional luxuries, if they happen to be easily available. There is nothing wrong with luxury in itself, but any dependence on luxuries is harmful to our happiness, as is every desire for unnecessary things.
To say that life is free is not to say that we don’t need to observe any moral constraints. It is a very bad plan to cheat on your friends or assault people in the street or do anything else that would cause you to worry about their reactions. Why is this a bad plan? Not because god has decreed that such things are ‘immoral’, but because it is stupid to do anything that would cause you to worry about anything.
One of the remarkable features of Epicurus’ philosophy is that it can be understood at several levels of subtlety. You don’t need to be a philosophical genius to grasp the main points, which is why Epicurus coined slogans and maxims for ordinary people to memorize, to help them relieve their anxiety whenever it might arise.

Interesting tidbits on intelligence and other subjects
From Scientific American online magazine, June 2011:
"Santiago Ramón y Cajal, the Spanish Nobel-winning biologist who mapped the neural anatomy of insects in the decades before World War I, likened the minute circuitry of their vision-processing neurons to an exquisite pocket watch. He likened that of mammals, by comparison, to a hollow-chested grandfather clock. Indeed, it is humbling to think that a honeybee, with its milligram-size brain, can perform tasks such as navigating mazes and landscapes on a par with mammals. A honeybee may be limited by having comparatively few neurons, but it surely seems to squeeze everything it can out of them.
At the other extreme, an elephant, with its five-million-fold larger brain, suffers the inefficiencies of a sprawling Mesopotamian empire. Signals take more than 100 times longer to travel between opposite sides of its brain—and also from its brain to its foot, forcing the beast to rely less on reflexes, to move more slowly, and to squander precious brain resources on planning each step.
- Human intelligence may be close to its evolutionary limit. Various lines of research suggest that most of the tweaks that could make us smarter would hit limits set by the laws of physics.
- Brain size, for instance, helps up to a point but carries diminishing returns: brains become energy-hungry and slow. Better “wiring” across the brain also would consume energy and take up a disproportionate amount of space.
- Making wires thinner would hit thermodynamic limitations similar to those that affect transistors in computer chips: communication would get noisy.
- Humans, however, might still achieve higher intelligence collectively. And technology, from writing to the Internet, enables us to expand our mind outside the confines of our body."
How Simple Photos Could Be Used as a Test for a Conscious Machine [Contest]
Join Scientific American's contest to show why conscious humans best unconscious computers and win a recently authored book by renowned neuroscientist Christof Koch
By Christof Koch and Giulio Tononi | Monday, June 13, 2011 | 14
WHAT'S WRONG WITH THIS PICTURE?: To judge that this image is incorrect, a machine would need to be conscious of many things about the world (unless programmed for just such a photograph). Image: Geof Kern
The mystery of human consciousness appears routinely as one of the greatest science problems of all time. One way to get a grip on this seemingly ineffable property would be to build a conscious machine. It may be many years before that happens. But the overriding question, when someone does try, will be: how will we know whether that machine is really conscious—and not merely faking it?
Probing a machine for consciousness need not require an elaborate mathematical construct. In fact, it might derive from something as simple as a street photo snapped with a cell phone camera, or you could use photo editing software to devise an image that just about any human would recognize is irrational or nonsensical, but that even today’s smartest computers might pass over as reasonable.
The authors define consciousness here as an ability to understand whether a photograph depicts an image that makes sense based on knowledge of the world that most people share—general knowledge that no present-day computer is capable of storing and processing in the way people do. A person, for instance, knows that a keyboard belongs in front of a computer screen, whereas a potted plant in that spot does not.
A computer might be able to win at Jeopardy, but it doesn’t have the basic common sense to understand that something is just plain wrong with the off-kilter juxtaposition of an iMac paired with a geranium. Koch and Tononi describe similar examples in their article, "A Test for Consciousness," available to readers free of charge. Even a six-year old, for instance, can pinpoint the fundamental improbability of an ice skater on the rug in the living room, a transparent cow or a cat chasing a dog. Yet a computer doesn’t "know” these things about the world.
These absurd yet simple images devised by the authors to illustrate this distinction between conscious human and unconscious computer led us to the idea of a contest in which readers could contribute their own examples of pictures that might fool a machine. Entries of digital images that display illogical imagery similar to what is described above can be submitted to ScientificAmerican.com for judging by Koch and Tononi and Scientific American editors (see the rules below). Koch and Tononi are the judges because unfortunately a real machine that could be used to carry out such a contest does not yet exist.

Princess Mediterranean Cruise
Notes to a friend on her upcoming trip of a same cruise.
I went back looking at my notes re. our Princess Mediterranean Cruise in 2008. Hopefully, some of this may be helpful on your upcoming trip.
Our trip started in Barcelona, Spain on Friday September 19, 2008 and ended in Venice, Italy on Oct 3, 2008. We flew home from Venice to Denver via Munich, Washing Dulles airport. The ports we visited were: Barcelona - Spain, Marseille - France, Livorno - Italy, Civitavecchia - Italy, Naples - Italy, Mykonos - Greece, Istanbul - Turkey, Kusadasi - Turkey, Athens - Greece, and Venice - Italy.
1. General suggestions: There will be lots of walking so comfortable shoes, socks, clothes are recommended. Long sleeve shirts, head scarf, long pants are required to visit St. Peter’s Cathedral in Rome and mosques, etc, ... in Istanbul. Bring some moleskin if long walks irritate your feet. A pouch with lanyard to keep passport, money inside shirt would deter most pickpockets. A hat, sun screen, sun glasses would also be helpful. It should be noted that it can get hot in the Mediterranean countries in summer. I also suggest you exchange a couple hundred US dollars to Euros at Las Vegas bank before leaving since the exchange rate and fees overseas and on ship can be more expensive.
If you can arrive in Barcelona a day ahead of the departure it would be nice to look up places to stay in Barcelona in travel books - Barnes and Nobles - by Rick Steeves or Lonely Planet. These books list current information re. recommended places to stay and cost. Since you'll be outside a lot there is no need to stay at an expensive hotel.
On your departure package from Princess Cruises you should have details re. departure location. Use Google Translate to translate it to Spanish and print it out: we nearly got lost from our Barcelona hotel to the ship embarkation location since the taxi driver did not speak English nor knew the area well.
There were some rough seas from Naples to Mykonos and from Athens to Venice. If you get sea-sick easily bring some medication/patch for it. There will be lots of English speakers around to help out. Pick-pockets and small time thieves have been known to pretend to help tourists take their pictures and run away with their camera. Bring several camera memory cards to take lots of pictures. Don't forget to bring the camera's charger. If necessary, you should call your cell phone company to see if there is a limited package for international calls.
Food costs in Europe can be quite expensive: the sit-down price is different from the take-out. We took fruits and non-perishable muffins, cheese from the ship with us when we went out. A small back-pack is also recommended for food, maps, note book, and camera.
I also recommend to Google the places that you will be visiting ahead of time to read about what to see, history, .. to put everything you'll see in a good context.
2. Places to see:
Barcelona, Spain: It is famous as the Gothic center of Spanish Catalan. The most well-known artist is Antoni Gaudi. His works are all over the city. the most famous one is the on-going construction of the Sagrada Familia (the Church of the Holy Family). It is a must see. The city is easy to walk around. There are many shops, stores and the foods were quite reasonably-priced and good. If you can, please walk down the famous La Rambla in central Barcelona.
Marseille, France: We did purchase some excursions with Princess before leaving home. In Marseille we went on a tour to charming Provence. Walking around Provence and its market place was fun.
In Livorno, Italy the ship arrived in port at 7:00am and left port at 6:30pm. It was enough time for a trip to Florence [Firenze in Italian]. This is a must see. The Firenze Cathedral called il Duomo is an incredible place to visit. Pay several euros to climb the Campanile which is a structure attached to il Duomo: you'll never regret it. Also please visit the world-famous bridge Ponte Vecchio which was so beautiful that Hitler's generals refused to blow it up during WW II retreat. All are within walking distance to the Piazza delle Signoria which has a replica of Michelangelo's David. Make sure to enjoy some of Firenze famous gelato!
In Civitavecchia, Italy the ship arrived in port at 7:00am and departed at 6:30pm. It was enough time for an excursion to Rome. I would suggest to pay for the Rome excursion since it would expedite entrance to the Vatican, Sistine Chapel instead of long wait. The most famous sites you must [sorry about this emphasis!] see are the Colosseum, the Trevis Fountain, the Spanish Steps, and of course St. Peter's Basilica which is the Vatican itself.
In Naples, we took the high speed hydrofoil to Capri. Immediately we purchased a funicular [hillside tram] to go up to the Capri town. It was a beautiful place to stroll and to take pictures. We did not have time to see the famous Blue Grotto.
Mykonos, Greece: we walked from the ship to town. It was a pleasant long walk several miles. However, I would recommend to take the bus there. There are lots of beautiful island pedestrian paths all over the town. Buy souvenirs but make sure to bargain!!
Istanbul, Turkey: there were so many famous places to see there. We did not see the Topkapi Palace nor the Hagia Sophia and regret it. We went to the Blue Mosque which was very crowded. Women are required to have a head scarf. Plastic bags were freely given to put our shoes inside. It was a good visit but not great. You will be greeted by friendly merchants bringing you to their stores which are also their houses trying to sell you Turkish rugs. We were charmed by two brothers inviting us to visit the massive and beautiful basement floor of their home. Unless one knows much about rugs I'd not recommend to buy anything. Try some of their foods sold in stores along many streets nearby. We went to the underground Istanbul Cistern and was amazed by the water aqueduct system.
Kusadasi, Turkey: we took the Princess excursion to Ephesus. It was spectacular!! The second stop of the same excursion was the home purportedly where Mary, mother of Jesus lived on her final years was good. I bargained and paid 1 Euro [the owner wanted 3 Euros] to have our picture taken leaning on a Turkish camel. It was hot so take some water with you.
Athens, Greece: we hiked the long walk to the Acropolis. It is an incredible site to see. Again, it was very hot and a somewhat arduous hike so bring lots of water. Many pedestrian-only marketplaces had great food, drinks and at reasonable prices. There were also lots of stores selling souvenirs. Again, bargain away.
Venice, Italy: Make sure to be on the top deck of the ship when it enters Venice. It was very beautiful and [hopefully] the ship captain will play Sarah Brightman and Andrea Bocelli's "Con te Partiro" (Time to say good-bye). You'll never forget it. You'll take the water bus (very inexpensive) from ship port to the Piazza San Marco! It is an unbelievable sight to marvel. Walk. Do not pay big bucks for the gondola rides. The food was spectacular. Get lost in the labyrinth of Venice and you'll love it.

Colorado Senate Bill 126
This bill, if passed, will be a new, added incentive for illegal immigration to our state. It will unfairly deny the much lower resident tuition to qualified students from outside of Colorado. Or to those left or leaving Colorado with their divorced parents for out-of-state jobs. In addition, there are possible several issues regarding the legality of this bill granting in-state tuition to children of federal immigration law-breakers.
Current Colorado severe fiscal constraint demands prudent and careful long-term control and management of resources. Colorado Senate Bill 126 will directly increase the budgetary deficit due to the financial subsidy to each in-state tuition-paying student.

On reading "A mathematician plays the stock market" by John Paulos
I am reading an interesting book "A mathematician plays the stock market" by John Allen Paulos. Paulos, a Temple University mathematics professor is the author of several best sellers including "Innumeracy: Mathematical Illiteracy and its Consequences", "Beyond Numeracy: Ruminations of a Numbers Man", "Irreligion: A Mathematician explains why the arguments for God just don't add up".
Here are some nuggets of wisdom I gleaned from "A mathematician plays the stock market".
"Uncertainty is the only certainty there is, and knowing how to live with insecurity is the only security." Paulos did not tell us not to invest in the stock market. He cautioned us about misunderstanding of applying mathematics to the stock market and investing. His humorous, interesting book includes explanation of scams, psychological blindness such as confirmation bias, and examples of investment mathematics mistakes and analyses. He admits to losing a bit of money himself during the dot-com boom in early 2000.
1. Psychological blindness. Paulos quoted John Maynard Keynes who likened the position of short-term stock market investors picking five prettiest out of hundred contestants in a newspaper. The rewards go to folks who correctly pick the contestants whom they think are most likely to be picked by other readers, and the other readers must try to do the same. This is what Paulos distinguishes between "Being right versus Being right about the Market". He then gave several interesting examples of mathematics involving game theory.
Other psychological blindness include emotional overreactions - the irrational exuberance- and despair. Paulos cited unfounded financial hype and unrealistic "price targets" which influence investors by putting an "anchoring effect" number to stock price.
2. The incoherent market pundits/analysts, blog and chat room noises. Many seemingly technical analyses are fundamentally wrong. There have been data mining and faulty attempts to discover investment scheme that supposedly worked in the past. An exhaustive search of the economic data on a United Nations CD-ROM in the mid-90s found the best predictor of the value of the S&P 500 stock index was - drum roll here - butter production in Bangladesh. He reminds us of the mathematically ignorant attempt to "decode" the Bible hidden codes to show that the September 11, 2001 event was "prophesied".
Paulos, through extensive but easy to follow mathematic examples in several chapters gave strong evidence that the technical analysis of trends, cycles, supporting and resistance stock price levels, waves, moving average are ridiculous and quasi-mathematical which seldom hangs together as a coherent theory. Many of current fads are just rehash of past failed theories; the Elliot wave theory to predict the behavior of stocks was based upon the Fibonacci number sequence. He boo-booed the claim that folks have made good money using the rules of technical analysis by saying that some other folks also make money in the stock market using strategies involving tea leaves and sun-spots!

Gout is gone
...
I saw a Joan Baez special on PBS yesterday evening and was quite impressed.
She has been a courageous woman with a very strong sense of social
justice. She also was a very attractive lady with beautiful voice and a talented guitar player. Her romantic songs of a bygone past brought me joyful sadness. Old pictures of the Vietnam war, marches in the South with Martin Luther King, Sarajevo, ... and Joan Baez's songs brought me the melancholy nostalgia of a time, place I thought has long forgotten.

Happiness
Yesterday evening we saw “Happiness”, an excellent PBS special.
Dr. Tal Ben Shabar is a Harvard professor teaching class about happiness. His thesis of ingredients for a happy life includes:
1. Simplification of life. The many choices that we have bring confusion and chaos. He proposes that we ought to simplify our life with simple pleasures; perform less multi-tasking activities; take time out to recover from stress.
2. Positive acceptance. This is not passivity. Positive acceptance means to make choice based upon available information; learning from mistakes and move on.
3. Exercise. Referenced many medical studies, Tal Ben Shabar posits that regular physical exercise reduces stress, disease risks, … which will lead to a happier, healthier life.
4. Happiness can be learned.
5. Mindful meditation. The simplest daily exercise is the deep breathing method. More advanced mindful meditation will further relaxation, stress-reduction and many other benefits.
6. Focus on the positives. An attitude of gratitude concentrating upon all the good things in our life is an important element for a happy life.
Tal Ben Shabar has written several best-sellers including “Happier” and “Pursuit of Perfect”.

Pan's Labyrinth - the Movie
by the many layers of interpretation of reality and un-reality, fantasy and religiosity,
dream vs. life, good vs evil... Especially, when all these layers are seamlessly interwoven into great story-telling with many subplots.
The last scene when Ofelia was killed is the most astounding: it brings up the historical context of the Spanish Civil War, the alliance of General F. Franco's dictatorship and the Catholic Church against the International Brigades. Her death and the afterlife sequence is the memorial of the deaths of many innocents during the War and the implication of martyrdom which ironically is on the side of the Church opponents; at the same time the evil of the Captain is explainable: he had a job to do and he could not see the faun Ofelia conversing with and I am sure that he believes that she was possessed and worse.
It was an incredible movie.

"The soul, being eternal, after death is like a caged bird that has been released. If it has been a long time in the body, and has become tame by many affairs and long habit, the soul will immediately take another body and once again become involved in the troubles of the world. The worst thing about old age is that the soul's memory of the other world grows dim, while at the same time its attachment to things of this world becomes so strong that the soul tends to retain the form that it had in the body. But that soul which remains only a short time within a body, until liberated by the higher powers, quickly recovers its fire and goes on to higher things."

What an astonishing thing a book is. It's a flat object made from a tree with flexible parts on which are imprinted lots of funny dark squiggles. But one glance at it and you're inside the mind of another person, maybe somebody dead for thousands of years. Across the millennia, an author is speaking clearly and silently inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. Books break the shackles of time. A book is proof that humans are capable of working magic.
