I've got a great story for you. A friend of mine sent it to me. He heard it on
a radio station in the US; they asked people to send in stories and this one was
read over the air. It was later printed on the station's website.
Sorry,
it's a long story, but give it a read. It's great.
Lori Peikoff from
Los Angeles calls her submission "Table for Two", but it also could have been
entitled "Great Expectations". In it, she tells the story of how her parents
met, as young people back in the late 1940s. They both lived in New York. Her
mother, Deborah, was a 21-year-old student at NYU. Her subject was English
literature. According to Ms Peikoff, she was beautiful—fiery, yet
introspective—with a great passion for books and ideas. She apparently read all
the time and hoped one day to become a writer. Her father, Joseph, was an
aspiring painter who supported himself by teaching art at a junior high school
on the West Side. On Saturdays, he would paint all day, either at home or in
Central Park, and treat himself to a meal out.
On the Saturday night in
question, he chose a neighborhood restaurant called Milky Way. The Milky Way
happened to be Deborah's favorite restaurant, and that Saturday, after studying
throughout the morning and afternoon, she went there for dinner, carrying along
a used copy of Dickens' Great Expectations to read while she ate. The
restaurant was crowded, and she managed to get the last free table. She settled
into her book and lost track of what was going on around her. After half an
hour, the restaurant had become so crowded that the frazzled hostess came over
to Deborah and asked if she would be willing to share her table with someone
else. Barely glancing up from her book, Deborah agreed. Joseph approached the
table, and when he saw the tattered cover of Great Expectations, he said, "A
tragic life for poor dear Pip". That was how it started. The attraction was
immediate, and to this day, Ms Peikoff's father swears that he heard these words
in his head as he sat down at the table: "She is your destiny", followed by a
tingling sensation that ran from the tip of his toes to the crown of his
head.
They talked for hours, both of them convinced that something
miraculous had happened, and when the evening was over, Deborah wrote her phone
number on the inside cover of Great Expectations and gave the book to Joseph.
He kissed her goodbye, and then they walked off in opposite directions and went
home. Neither one of them slept that night. Deborah could only see one thing:
Joseph's face. And Joseph, who could not stop thinking about Deborah, statyed
up for hours painting her portrait.
The next day, Sunday, he was supposed
to go out to Brooklyn to see his parents. He carried the book with him and
started reading it on the subway, but he was exhausted after his sleepless
night, and so he slipped the book into the pocket of his coat—which he had put
on the empty seat next to him—and closed his eyes. He didn't wake up until the
train stopped at Brighton Beach—at the far edge of Brooklyn—and when he opened
his eyes, his coat was no longer there. Someone had stolen it, along with the
book inside it. This might not have been such a tragedy if not for the fact
that the telephone number—which was written inside the book—was his only link to
Deborah. In his excitement over meeting her the night before, he had stupidly
neglected to find out her last name. Months passed. The call that Deborah was
expecting to receive from Joseph never came, and although Joseph went looking
for her several times at the NYU English Department, he could never find
her.
Destiny had betrayed them both, and what had seemed inevitable that
first night in the restaurant was apparently not meant to be. That summer,
Deborah went to England to take literature courses at Oxford, and Joseph went to
Paris to paint. In late July, with a three-day break in her studies, Deborah
decided to visit Paris, where she had never been before. She carried along a
new copy of Great Expectations for the trip. After the incident with Joseph,
she hadn't had the heart to read it, but now, as she sat down in a crowded
restaurant after a long day of sight-seeing, she opened it to the first page and
started thinking about him again. After reading a few sentences, she was
interrupted by the maitre d' who asked her, first in French, then in broken
English, if she wouldn't mind sharing her table. She agreed and then returned
to her reading. A moment later, she heard a familiar voice. "A tragic life for
poor dear Pip," the voice said, and then she looked up, and there he was
again.

Become an Early Riser
I have seen this simple, practical strategy help many people discover a more peaceful, even a more meaningful life.
So many people wake up, rush to get ready, grab a cup of coffee, and charge out the door to work.
After working all day, they return home, tired.
The same is usually true for men and women who stay home with their children: They get up just in time to start doing things for the kids.
There is virtually no time for anything else.
Whether you work, raise a family, or both, for the most part you are too tired to enjoy any time left for you.
As a solution to the tiredness, the assumption is often made, "I'd better get as much sleep as I can."
So, your free time is spent sleeping.
For many people this creates a deep longing in the heart.
Surely there must be more to life than work, children, and sleep! Another way of looking at your fatigue is to consider that a lack of fulfillment and a sense of being overwhelmed both contribute to your tiredness.
And, contrary to popular logic, a little less sleep and a little more time for you might be just what you need to combat your sense of fatigue.
An hour or two that is reserved just for you-before your day begins-is an incredible way to improve your life.
I usually get up between 3 and 4 in the morning.
After a quiet cup of coffee, I usually spend some time doing yoga and a few minutes of meditation.
After that, I will usually go upstairs and write for a while, but I also have time to read a chapter or two in whatever book I'm enjoying.
Sometimes I'll just sit for a few minutes and do nothing.
Virtually every day, I stop whatever I'm doing to enjoy the sunrise as it comes up over the mountain.
The phone never rings, no one is asking me to do anything for them, and there is nothing I absolutely have to do.
It's by far the most quiet time of the day.
By the time my wife and children wake up, I feel as though I've had a full day of enjoyment.
No matter how busy I am that day or whatever demands there are on my time, I know I've had "my time."
I never feel ripped off (as so many people unfortunately do), as if my life isn't my own.
I believe this makes me more available for my wife and children, as well as my clients at work and other people who depend on me.
Many people have told me that this one shift in their routine was the single most important change they have ever made in their lives.
For the first time ever, they are able to participate in those quiet activities they never found the time to do.
All of a sudden, the books are getting read, the meditation gets done, the sunrise is appreciated.
The fulfillment you experience more than makes up for any sleep you miss out on.
If you must, turn off the television at night and get to sleep an hour or two earlier.
Don't sweat small stuff
Gallup: 7 in 10 Republicans don't believe in
Evolution
Mon Jun 11, 2007 at 02:00:18 PM PDT
Gallup has just released a scary new poll that
indicates just how much work still lies before us as a nation--and just how
frightening is the prospect of Republican rule. The majority of Americans are
still likelier to believe in creationism than in evolution--with an amazing 7
out of 10 Republicans holding fast to their literalist beliefs.
Most depressingly, the figures for the American people in general have not
moved significantly since 1982--both according to the Gallup polls and a number
of others. The fantastic site Polling
Report has a rundown of the major polls on just about every major
sociopolitical issue, including evolution and politics. The
numbers are anything but encouraging: in 1982, 38% of Americans thought that
human beings were created over the course of millions of years, but God guided
the process; 9% thought God played no part; and 44% said we were created by God
in our current form (9% stated "other"). In 2007, those numbers have shifted
only slightly, with 38% for divine guidence, 14% for no divine role, and 43% for
creationism. A 2005
Harris poll showed 6% fewer Americans believing in human evolution
than they had in 1994.
While the overall numbers for Americans are depressing, the political divide
is nothing short of astonishing. As Gallup says:
The majority of Republicans in the United States do not believe the theory of
evolution is true and do not believe that humans evolved over millions of years
from less advanced forms of life. This suggests that when three Republican
presidential candidates at a May debate stated they did not believe in
evolution, they were generally in sync with the bulk of the rank-and-file
Republicans whose nomination they are seeking to obtain.
Independents and Democrats are more likely than Republicans to believe in the
theory of evolution. But even among non-Republicans there appears to be a
significant minority who doubt that evolution adequately explains where humans
came from.
The partisan numbers are 68% creationism to 30% evolution among
Republicans, and 57% evolution to 40% creationism among Democrats. Of
course, the divide between those who attend church regularly and those who do
not is far larger (74% creationism to 24% evolution among those who attend
church weekly, compared with 71% to 26% the other way), but that is largely to
be expected. It is also important to note that many Americans appear to hold
somewhat conflicted and contradictory beliefs. As Gallup goes on to say:
The data indicate some seeming confusion on the part of Americans on this
issue. About a quarter of Americans say they believe both in evolution's
explanation that humans evolved over millions of years and in the creationist
explanation that humans were created as is about 10,000 years ago...
<snip>
It might seem contradictory to believe that humans were created in their
present form at one time within the past 10,000 years and at the same time
believe that humans developed over millions of years from less advanced forms of
life. But, based on an analysis of the two side-by-side questions asked this
month about evolution and creationism, it appears that a substantial number of
Americans hold these conflicting views.
While I have no direct evidence to support this claim, I think it stands to
reason that more moderates, independents and Democrats are likely to hold
contradictory beliefs on this issue: I know several religious Democrats who
stick to the principle that science and faith are entirely separate, and willing
to live with a contradictory dichotomy between the Bible's literal words and the
scientific evidence. Such contradictory beliefs are not generally in keeping
with the dogmatic views of the fundamentalist Christians who tend to reject
scientific evidence entirely.
Most interesting and underreported in stories covering this issue,
however, are the numbers among independents: a full 61% of independents
believe in evolution, compared to 37% for creationism--a higher belief in
evolution than among Democrats. Factoring in the stunning increase
in the number of voters who call themselves Independent (32.9% of the
population), this is but another example of a strong majority of "swing" voting
population moving away from bread-and-butter Republican beliefs in some pretty
fundamental issues. It is a scary thing for a rightist political party when
Independents actually stand to the left of the bulk of the Left's party
constituents.
Gallup sums it up nicely:
Being religious in America today is strongly related to partisanship, with
more religious Americans in general much more likely to be Republicans than to
be independents or Democrats. This relationship helps explain the finding that
Republicans are significantly more likely than independents or Democrats to say
they do not believe in evolution. When three Republican presidential candidates
said in a May debate that they did not believe in evolution, the current
analysis suggests that many Republicans across the country no doubt agreed.
To me, the upshot is this: we have an increasingly hostile ideological divide
in this country between the two parties, with one side avowedly in favor of
Luddite ignorance when it comes to evolution, and the other with a solid
majority of more reasoned (if often contradictory) beliefs. And while the views
of the American public at large in this deeply divided country have not shifted
dramatically, the views of Independent voters have swung sharply in the
direction of Democrats--and on a fundamental issue that is not subject to
prevailing political winds or current events.
Once again, we have a situation where the differences between the two parties
could not be more clear; where the Republican Party is showing itself to be
increasingly irrational, dangerous, and in hock to the extreme Christianist
right; and where the Democratic Party has little to lose with crucial swing
voters by standing strong on its principles.
Because to put it bluntly, in the year 2007, a party accountable to a
constituency with a supermajority of believers in Biblical literalism simply
cannot be allowed to rule. We have seen the consequences of such
willful ignorance for the last 6 years, and we can no longer afford to be
patient with it.

Ayahs of the Day: If God were to
punish people for their injustice, not a single creature would be left on earth:
but God leaves them be until a determined time. And when their time has come,
they cannot postpone it even an hour nor yet bring it on. [16:
61]
Hadith of the Day:
Protect (yourselves) from the
earth for it is your mother and there is no one who does any act, good or evil,
except that it will tell about it. [Tabrani]
Wise Quote of the
Day:
Beware, beware! For God has been so protective that it almost
seems like Divine forgiveness. [Ali radi Allah anhu]

Food for Thought: Most people are
searching for happiness. They're looking for it. They're trying to find it in
someone or something outside of themselves. That's a fundamental mistake.
Happiness is something that you are, and it comes from the way that you
think.

Ayahs of the Day:
But if they turn
away, your only obligation is clear communication. They recognize the kindness
of God, but they deny it, as most of them are ingrates. [16:
82,83]
Hadith of the Day:
The best of you are those
who, when you look at them, you remember Allah. [Tirmidhi]
Wise
Quote of the Day:
How strange is the one who knows Satan to be his
enemy and yet listens to him obediently. [Othman radi Allah
anhu]
Guidance of the Day:
Schedule time for your
inner work. In the field of financial planning there is a universally
accepted principle that it's critical to pay yourself first, before you pay your
other bills--to think of yourself as a creditor. The rationale for this wisdom
is that if you wait to put money into savings until after everybody else is
paid, there will be nothing left for you. The result is that you'll keep
postponing your savings plan until it's too late to do anything about it. But,
if you pay yourself first, somehow there will be just enough to pay everyone
else too.
The identical principle is critical to implement into your
program of spiritual practice. If you wait until all your chores,
responsibilities, and everything else is done before you get started, it will
never happen. Guaranteed. Scheduling a little time each day as if it were an
actual appointment is the only way to ensure that you take some time for
yourself. You might become an early riser, for example, and schedule one hour
that is reserved for reading, praying, reflecting, meditating, exercise, or
however you want to use the time. How you choose to use your time is up to you.
The important thing is that you do schedule the time and that you stick to it.
If you set your mind to it, you can find the time you need. [Don't Sweat The
Small Stuff]
Food for Thought:
When you truly know
that your life has a grand and heroic mission, then you will realign yourself as
a spiritual being.

Yet Daniel Goleman, author of Social Intelligence: The New Science of Human
Relationships, argues that as humans we are wired for sociability. He gives a
cogent example of today’s frequently self-centered discourse when he describes a
woman whose sister had recently died getting a phone call from a supposedly
concerned friend. As she goes into detail about her grief, the woman hears her
friend typing on the keyboard, answering his email. This sort of detachment
where dialogues become monologues was described by the late philosopher Martin
Buber as an “I It” interaction where “one person has no attunement to the
other’s subjective reality.” Goleman states that Buber used “I It” to describe
“the range of relations that runs from merely detached to utterly exploitive.”

We Earth Neurons
Daniel
Dennett on knowledge
sharing and the fate of the planet,
in which he contrasts individuals and their brains with the trillions of
neurons that compose them. The planet
has grown its own nervous system:
us.
Originally
published as an academic paper on August 15, 1999. Published on
KurzweilAI.net September 18, 2001.
Some years
ago a friend of mine in the Peace Corps told me about his efforts on behalf
of a tribe of gentle Indians deep in the Brazilian forest. I asked him if he
had been required to tell them about the conflict between the USA and the
USSR. Not at all, he replied. There would be no point in it. They had not
only never heard of either America or the Soviet Union, they had never even
heard of Brazil! Who would have guessed that it is still possible to be a
human being living in, and subject to the laws of, a nation without the
slightest knowledge of that
fact? If we find this astonishing, it is because we human beings, unlike all
other species on the planet, are knowers. We are the
ones--the only ones--who have figured out what we are, and where we
are, in this great universe.
And we are even beginning to figure out how we got here.
These quite
recent discoveries are unnerving, to say the least. What you are--what each
of us is--is an assemblage of roughly a trillion cells, of thousands of
different sorts. Most of these cells are "daughters" of the egg and
sperm cell whose union started you (there are also millions of hitchhikers from
thousands of different lineages stowed away in your body), but each cell is a
mindless mechanism, a largely autonomous micro-robot, no more conscious than
a bacterium, and not a single one of the cells that compose you knows who you
are, or cares.
Each
trillion-robot team is gathered together in a breathtakingly efficient regime
that has no dictator but manages to keep itself organized to repel outsiders,
banish the weak, enforce iron rules of discipline--and serve as the
headquarters of one conscious self, one mind. These communities of cells are
fascistic in the extreme, but your interests and values have almost
nothing to do with the limited goals of the cells that compose
you--fortunately. Some people are gentle and generous, others are ruthless;
some are pornographers and others devote their lives to the service of God, and it has been tempting over the
ages to imagine that these striking differences must be due to the special
features of some extra thing (a soul) installed somehow in the bodily headquarters, but what
we now have figured out is that there is no such extra ingredient; we are
each madeof mindless robots and nothing
else, no non-physical, non-robotic ingredients at all. The differences
between people are all due to the way their particular robotic teams are put
together, over a lifetime of growth
and experience. The
difference between speaking French and speaking Chinese is a difference in
the organization of the working parts, and so are all the other differences
of personality--and knowledge.
Four and a
half billion years ago, the earth was formed, and it was utterly without
life. And so it stayed for perhaps as long as a billion years. For another
billion years, the planet's
oceans teemed with life, but it was all blind and deaf. Simple cells
multiplied, engulfing each other, exploiting each other in a thousand ways,
but oblivious to the world beyond their membranes. Then much larger, more
complex cells evolved--eukaryotes--still clueless and robotic, but with
enough internal machinery to begin to specialize. So it continued for more
than two billion more years, the time it took for the algorithms of evolution to hit upon good ways of
banding these workers together into multi-cellular organisms composed of
millions, billions and, (eventually) trillions of cells, each doing its
particular mechanical routine, but now yoked into specialized service, as
part of an eye or an ear or a lung or a kidney. These organisms (not the individual team members
composing them) had become long-distance knowers, able to spy supper
trying to appear inconspicuous in the middle distance, able to hear danger
threatening from afar. But still, even these whole organisms knew not what
they were. Their instincts guaranteed that they tried to mate with the right
sorts, and flock with the right sorts, but just as those Brazilians didn't
know they were Brazilians, no buffalo has ever known it's a buffalo.
In just one
species, our species, a new trick evolved: language. It has provided us a broad
highway of knowledge-sharing,
on every topic. Conversation
unites us, in spite of our different languages. We can all know quite a lot
about what it is like to be a Vietnamese fisherman or a Bulgarian taxi
driver, an eighty-year-old nun or a five-year-old boy blind from birth, a
chess master or a prostitute. No matter
how different from one another we people are, scattered around the globe, we
can explore our differences and communicate about them. No matter how similar to one another
buffalos are, standing shoulder to shoulder in a herd, they cannot know much
of anything about their similarities, let alone their differences, because
they can't compare notes. They can have similar experiences, side by side,
but they really can't share experiences the way we do.
Even in our
species, it has taken
thousands of years of communication
for us to begin to find the keys to our own identities. It has been only a
few hundred years that we've known that we are mammals, and only a few
decades that we've understood in considerable detail how we have evolved,
along with all other living things, from those simple beginnings. We are
outnumbered on this planet
by our distant cousins, the ants, and outweighed by yet more distant
relatives we share with the ants, the bacteria, but though we are in the
minority, our capacity
for long-distance knowledge
gives us powers that dwarf the powers of all the rest of the life on the planet. Now, for the first time in its
billions of years of history,
our planet is protected by
far-seeing sentinels, able to anticipate danger from the distant future--a comet on a collision course,
or global warming--and
devise schemes for doing something about it. The planet has finally grown its own nervous
system: us.
We may not
be up to the job. We may destroy the planet
instead of saving it, largely because we are such free-thinking, creative, unruly explorers and
adventurers, so unlike the trillions of slavish workers that compose us.
Brains are for anticipating the future,
so that timely steps can be taken in better directions, but even the smartest
of beasts have very limited time horizons, and little if any ability to
imagine alternative worlds. We human beings, in contrast, have discovered the
mixed blessing of being able to think even about our own deaths and beyond,
and a huge portion of our energy
expenditure over the last ten thousand years or so has been devoted to
assuaging the concerns provoked by this unsettling new vista. If you burn
more calories than you take in, you soon die. If you find some tricks that
provide you a surplus of calories, what might you spend them on? You might
devote person-centuries of labor to building temples and tombs and
sacrificial pyres on which you destroy some of your most precious
possessions--and even some of your very own children. Why would you want to
do that? These strange and awful expenditures give us clues about some
of the hidden costs of our heightened powers of imagination. We did not
come by our knowledge
painlessly.
Now what
will we do with our knowledge?
The birth-pangs of our discoveries have not subsided. Many are afraid that learning too much about what we
are--trading in mystery for mechanisms--will impoverish our vision of human
possibility. This fear is ill-considered. Look around at those who are
eagerly participating in this quest for further knowledge and embracing the new
discoveries; they are manifestly not bereft of optimism, moral conviction, engagement
in life, commitment to society.
In fact, if you want to find anxiety, despair, anomie today, look
among the undereducated young people scavenging their dimly understood
heritages (or popular culture) for a comfortable identity. Among intellectuals, look to
the fashionable tribe of postmodernists, who would like to suppose that
modern science is just another
in a long line of myths, its institutions and expensive apparatus just the
rituals and accouterments of yet another religion. That intelligent people can
take this seriously is a testimony to the power that fearful thinking still has, in spite of our
advances in self-consciousness.
The postmodernists are right, of course, that science is just one of the things we
might want to spend our extra calories on. The fact that science has been the major source of the
efficiencies that created those extra calories does not entitle it to any
particular share of the wealth
it has created. But it still ought to be obvious that the methods and rules
of science--not just its
microscopes and telescopes and computers--are the new sense organs of our species, enabling us to answer
questions, solve mysteries, and anticipate the future in ways no earlier human institutions
can approach. The more we learn about what we are, the more options we will
discern about what to try to become. We Americans have long honored the
"self-made man" but now that we are actually learning enough to be able to re-make
ourselves into something new, many flinch. Many people would apparently
rather bumble around with their eyes closed, trusting in tradition, than look
around to see what's about to happen. Yes, it is unnerving; yes, it can be
scary. After all, there are many entirely new mistakes we are now empowered
to make. But it's the beginning of a great new adventure for our knowing species--and much more exciting, as well
as safer, if we open our eyes.

'Guessing' robots find their way
|
The robots use educated "guesswork" to find their way around
|
Robots that
use "guesswork" to navigate through unfamiliar surroundings are being developed
by US researchers.
The mobile machines create maps of areas they have already explored and then
use this information to predict what unknown environments will be like.
Trials in office buildings showed that the robots were able to find their way
around, New Scientist reported.
Making robots that can navigate without prior knowledge of their surroundings
was a huge challenge, the team said.
|
It works well in indoor environments
|
Most mobile robots do this using a technique called SLAM (simultaneous
localisation and mapping), whereby they build up a map of their unknown
environment, using various sensors, whilst keeping track of their current
position at the same time.
But this technique is slow because a robot must explore a great deal of
terrain to know its precise location. It is also prone to errors.
So the team from Purdue University, in Indiana, has developed a new approach.
The robots create a 2D map of the area they are exploring, but when they come
to an unknown area, they check back through this information to see if it seems
similar to any areas that have already explored.
They do this using an algorithm - a step-by-step problem solving procedure.
Professor George Lee who carried out the research, said: "The robot gets to a
new area and thinks: 'Have I seen these sorts of things before?' Then it goes
back and looks at its stored data.
"It might then think: 'Hey, this is very, very similar to something I've seen
before, I don't need to explore that room or corner.' And this saves time for it
to explore other areas."
He said it was similar to the human navigational process, where we build up a
"mental map" of our surroundings by recognising familiar sights.
Some limitations
The scientists first tested the algorithm using virtual mazes and offices.
Their computer models revealed that the robots could navigate successfully while
exploring a third less of their environment than robots that simply used SLAM.
Then tests carried out using real robots inside a university office building
showed that the new navigation technique was also faster and less prone to
errors than SLAM.
However, the new method did have some limitations, Professor Lee said.
"Indoors, in places like office buildings, it works well; outdoors, where the
scene isn't as repetitive, the result is not that good."
Self-navigating robots could have many applications, Professor Lee told the
BBC News Website.
The US defence department is currently focusing on self-driving automobiles.
Professor Lee's research was funded by the National Science Foundation and
was published in the journal IEEE Transactions on Robotics.

Ready To Lend A Hand
Asia's youth are often characterized as money-grubbing
"me-firsters." But increasingly, the region's new rich are looking to help
others. Meet the "we generation."
The humanitarian response to the 2004 asian tsunami was swift and global. But
of all the tasks outside relief agencies and foreign soldiers undertook, none
was as grim as that assigned to the Indonesian volunteers in Banda Aceh dubbed
"the body-snatchers." Their mission: to clear the provincial capital of
putrefying corpses, both to preserve the dignity of the tens of thousands of
victims and to prevent epidemics among survivors. For weeks, they inched
quadrant by quadrant through the wrecked cityscape, freeing decomposing remains
from the rubble for burial in mass graves. "It was very, very surprising," says
Hasballah M. Saad, an Indonesian human-rights commissioner. "We never imagined
that people would come spontaneously."
The volunteers' sacrifices were emblematic of an underappreciated force in
modern Asia: the power of
community. Time and again, the region's globalized youth are cast as
money-grubbing me-firsters--which is to say, the 21st century's version of
America's post-World War II baby boomers. In Japan, leaders
castigate the "parasite singles" who live at home in suspended adolescence; in
Singapore, they fret about the younger generation's propensity to avoid the
costs and cares of child-rearing. Everywhere the premise that an Asian "me
generation" has emerged is seldom if ever challenged. After all, study after
study has plotted the rise of millions of new consumers across the region,
noting that global economic growth increasingly hinges on the buying power of
well-to-do households in places like Shanghai, Jakarta and Mumbai. One would
think that all they want to do--and all the world wants them to do--is spend,
spend, spend.
Such observations aren't so much wrong as one-dimensional. History shows that
industrializing countries evolve--often radically--with each successive
generation. So in light of Asia's breakneck modernization, it's little wonder
that values are changing fast. But alongside the spread of unbridled capitalism
and conspicuous consumption, the region is also experiencing a profusion of new
nongovernmental organizations (NGOs), a religious resurgence and rising
nationalism. There are estimated 2 million NGOs in India, and China now has
2,000 registered "green" groups--up from zero in the early 1990s. In Indonesia,
students from the top three universities in the country were surveyed on their
career plans in 2004. An astonishing 73 percent said they would prefer to work
for an NGO than for the government, and about the same number said civic
organizations could do more than government to improve the country. In these
Asian countries and others, the operative pronoun is "we"--the power of groups
to enhance the common good.
In fact, the interplay between individualism and collective action underpins
much of Asia's dynamism. One example is modern-day Bangladesh. Infamous for bad
governance and incessant civil unrest, the country of 145 million has
nonetheless become the least-developed world's overachiever. Its gravity-defying
economy is expected to grow by 6.7 percent this year, and the country is on
track to meet its United Nations-mandated millennium development goals on
poverty reduction, gender equality, literacy and rural development.
But how? One growth driver is the millions of grass-roots enterprises funded
by small-scale loans extended without collateral to poor households. The other:
a vibrant, youth-oriented NGO community that bolsters educational and health
services. "The government is wobbly and ineffective," says micro-credit pioneer
Muhamad Yunus, founder of Dhaka-based Grameen Bank and winner of this year's
Nobel Peace Prize. "But our NGOs are strong and getting stronger, and they focus
on the issues we need them to."
Disorienting change can inspire what looks like selfish behavior, to be sure,
as rapid economic growth destroys traditional social structures faster than new
ones can be built. One example is the magnetic pull boomtowns like Guangzhou, Ho
Chi Minh City or Bangalore exert on the best and brightest young talent in their
respective countries. Often, the rural migrants who make good in the city find
themselves disconnected and alone. "Initially, a lot of their riches go to
satisfying selfish demands," says Shalabh Sahai, a 30-year-old resident of
Mumbai who received his M.B.A. from the prestigious Indian Institute of Rural
Development in Anand.
But, Sahai goes on to note, "as the number of these people increases and they
get more experience, many begin to say 'I should do something more'." That was
his thinking when he joined two classmates to form the nonprofit group
iVolunteers back in 2002. The group, which has 9,000 active members in four
cities, seeks to link young elites with suitable needy causes. Since its
inception the matchmaking service has arranged for thousands of
volunteers--mostly IT professionals or bankers aged 25 to 35--to mentor orphans,
teach slum kids to trek, visit old folks homes or advise grassroots
environmental groups.
"We have a lot of young people who are extremely intelligent and earn big
salaries," says 27-year-old Misha Bhatt, who heads the group's Mumbai operation.
"They meet others, brainstorm solutions to problems. The feel-good factor is
extremely high." iVolunteers, which is expanding its services through links with
companies also looking to do good, reflects a signal change in India: The
tradition of village-level charitable giving is being replaced by corporate and
individual giving, coming from cities and the new rich.
Different countries in the region are naturally at different stages. In
China, grassroots activism dealing with anything other than environmental issues
is largely suspect; Beijing severely curtails the formation of independent NGOs.
In many ways the bigger challenge is to foster a sense of community within the
workplace, as so many of the so-called little emperors born under China's
one-child policy start their careers. Employers report that screaming matches,
crying jags and other sandbox antics have become commonplace, as has job-hopping
fueled by low job satisfaction. New hires often "come with a sense that the
rules don't apply to me," says William Dodson, CEO of Silk Road Advisors, a
Suzhou-based management consultancy. "The next five to 10 years are going to be
rough."
And in fact, less individualism is not always a good thing. In Malaysia last
week, Prime Minister Abdullah Ahmad Badawi warned that religious and ethnic
tensions could cause the country "to fail as a multiracial and multireligious
nation." His comments followed recent clashes between Malay Muslims and ethnic
Chinese, many of whom are Christian. On Internet bulletin boards in Japan, South Korea
and China, young nationalists trade slurs over everything from Japan's
20th-century imperialism to North Korea's recent nuclear test--suggesting that
economic integration doesn't always portend warm diplomatic relations. In South
Korea, President Roh Moo Hyun has edged his government steadily away from
Washington, its mainstay cold-war ally, into a more neutral position vis-à-vis
Pyongyang. That shift appeals to Roh's young political base, which is
left-leaning, pro-unification, and favors egalitarian economic policies. In many
Asian countries--and certainly in China, Japan and Korea--the younger generation
is more willing than their parents to wear their nationalism on their
shirtsleeves.
But at least the passion shows that Asians have more on their minds than just
making money. Take the Muslim
Student Association at the University of the Philippines in Manila, an elite
training ground for future business and political leaders. Its members, many of
them from impoverished Mindanao, are
eager to serve their home communities. Association President Abdel Jamal
Disangcopan, 22, is the son of two doctors. He attends law school but doesn't
dream of becoming a highly paid corporate lawyer. "Money is just a plus.
Fulfillment is first," he says. "I don't want to be stuck in a life where ...
I'm not helping anybody." He aims to return to Mindanao and become a much-needed
public defender. Another student in the Muslim Student Association says she
wants to return to Mindanao to practice medicine, after she earns her degrees,
and a third plans to return to become a teacher. All are likely to make good on
their pledges--making small but invaluable contributions to the societies in
which they live.

Section 5 Dangerous
Beauty
The following
is an excerpt from "A Short History of Nearly Everything" by Bill Bryson This is a wonderful book, and I would heartily recommend it as required
reading to any serious student of this Wonderful World.
In the 1960's, while studying the volcanic history of Yellowstone National Park,
Bob Christiansen of the United States Geological Survey became puzzled about
something that, oddly, had not troubled anyone before: he couldn't find the
park's volcano. It had been known for a long time that Yellowstone was volcanic
in nature--that's what accounted for all its geysers and other steamy
features--and the one thing about volcanoes is that they are generally pretty
conspicuous. But Christiansen couldn't find the Yellowstone volcano anywhere.
In particular what he couldn't find was a structure known as a caldera.
Most of us, when we think of volcanoes, think of the classic cone
shape of Fuji or Kilimanjaro, which are created when erupting magma accumulates
in a symmetrical mound. These can form remarkably quickly. In 1943, at
Paricutin in Mexico, a farmer was startled to see smoke rising from a patch on
his land. In one week he was the bemused owner of a cone five hundred feet
high. Within two years it had topped out at almost fourteen hundred feet and
was more than a half mile across. Altogether there are some ten thousand of
these intrusively visible volcanoes on Earth, all but a few hundred of them
extinct. But there is a second, less celebrated type of volcano that doesn't
involved mountain building. These are volcanoes so explosive that they burst
open in a single mighty rupture, leaving behind a vast subsided pit, the caldera
(from a Latin word for cauldron). Yellowstone was obviously of this second
type, but Christiansen couldn't find the caldera anywhere.
By
coincidence just at this time NASA decided to test some new high altitude
cameras by taking photographs of Yellowstone, copies of which some thoughtful
official passed on to the park authorities on the assumption that they might
make a nice blow-up for one of the visitors' centers. As soon as Christiansen
saw the photos he realized why he had failed to spot the caldera: virtually the
whole park--2.2 million acres--was caldera. The explosion had left a crater
more than forty miles across--much too huge to be perceived from anywhere at
ground level. At some time in the past Yellowstone must have blown up with a
violence far beyond the scale of anything known to humans.
Yellowstone, it turns out, is a supervolcano. It sits on top of an enormous hot
spot, a reservoir of molten rock that rises from at least 125 miles down in the
Earth. The heat from the hot spot is what powers all of Yellowstone's vents,
geysers, hot springs, and popping mud pots. Beneath the surface is a magma
chamber that is about forty-five miles across--roughly the same dimensions as
the park--and about eight miles thick at its thickest point. Imagine a pile of
TNT about the size of Rhode Island and reaching eighty miles into the sky, to
about the height of the highest cirrus clouds, and you have some idea of what
visitors to Yellowstone are shuffling around on top of. The pressure that such
a pool of magma exerts on the crust above has lifted Yellowstone and about three
hundred miles of surrounding territory about 1,700 feet higher than they would
otherwise be. If it blew, the cataclysm is pretty well beyond imagining.
According to Professor Bill McGuire of University College London, "you wouldn't
be able to get within a thousand kilometers of it" while it was erupting. The
consequences that followed would be even worse.
Superplumes of the
type on which Yellowstone sits are rather like martini glasses--thin on the way
up--spreading out as the near the surface to create vast bowls of unstable
magma. Some of these bowls can be up to 1200 miles across. According to
theories, they don't always erupt explosively but sometimes burst forth in a
vast, continuous outpouring--a flood--of molten rock. Superplumes probably
contributed to the demise of the dinosaurs, and may also be responsible for the
rifts that cause continents to break up.
Such plumes are not all that
rare. There are about thirty active ones on the Earth at the moment, and they
are responsible for many of the world's best-known islands and island
chains--Iceland, Hawaii, the Azores, Canaries and Galapagos archipelagoes,
little Pitcairn in the middle of the South Pacific, and many others--but apart
from Yellowstone they are all oceanic. No one has the faintest idea how or why
Yellowstone's ended up beneath a continental plate. Only two things are
certain: that the crust at Yellowstone is thin and that the world beneath it is
hot. But whether the crust is thin because of the hotspot, or whether the hot
spot is there because the crust is thin is a matter of heated (as it were)
debate. The continental nature of the crust makes a huge difference to its
eruptions. Where other supervolcanoes tend to bubble away steadily and in
comparatively benign fashion, Yellowstone blows explosively. It doesn't happen
often, but when it does you want to stand well back.
Since its first
know eruption 16.5 million years ago, it has blown up about a hundred times, but
the most recent three eruptions are the ones that get written about. The last
eruption was a thousand times greater than that of Mount St. Helens; the one
before that was 280 times bigger, and the one before that was so big that nobody
knows exactly how big it was. It was at least twenty-five hundred times greater
than St. Helens, but perhaps eight thousand times more monstrous.
We
have absolutely nothing to compare it to. The biggest blast in recent times was
that of Krakatau in Indonesia in August 1883, which made a bang that
reverberated around the world for nine days, and made water slosh as far away as
the English Channel. But if you imagine the volume of ejected material from
Krakatau as being about the size of a golf ball, then the biggest of the
Yellowstone blasts would be the size of a sphere you could just about hide
behind. On this scale, Mount St. Helens would be no more than a pea.
The Yellowstone eruption of two million years ago put out enough ash to bury New
York State to a depth of sixty-seven feet or California to a depth of twenty.
This ash made fossil beds in eastern Nebraska. That blast occurred in what is
now Idaho, but over millions of years, at a rate of about one inch a year, the
Earth's crust has traveled over it, so that today it is directly under northwest
Wyoming. In its wake it leaves the sort of rich volcanic plains that are ideal
for growing potatoes, as Idaho's farmers long ago discovered. In other two
million years, geologists like to joke, Yellowstone will be producing French
fries for McDonald's, and the people of Billings, Montana, will be stepping
around geysers.
The ash fall from the last Yellowstone eruption
covered all or parts of nineteen western states (plus parts of Canada and
Mexico)--nearly the whole of the United States west of the Mississippi. This,
bear in mind, is the breadbasket of America, an area that produces roughly half
the world's cereals. And ash, it is worth remembering, is not like a big
snowfall that will melt in the spring. If you wanted to grow crops again, you
would have to find some place to put all of the ash. It took thousands of
workers eight months to clear the 1.8 billion tons of debris from the sixteen
acres of the World Trade Center site in New York. Imagine what it would take to
clear Kansas.
And that's not even to consider the climatic
consequences. The last supervolcano eruption on Earth was at Toba, in northern
Sumatra, seventy four thousand years ago. No one knows quite how big it was
other than it was a whopper. Greenland ice cores show that the Toba blast was
followed by at least six years of "volcanic winter" and goodness knows how many
poor growing seasons after that. The event, it is thought, may have carried
humans right to the brink of extinction, reducing the global population to no
more than a few thousand individuals. There is some evidence to suggest that
for the next twenty thousand years the total number of people on Earth was never
more than a few thousand at any time. That is, needless to say, a long time to
recover from a single volcanic blast.
All of this was hypothetically
interesting until 1973, when an odd occurrence made it suddenly momentous:
water in Yellowstone Lake, in the heart of the park, began to run over the banks
at the lake's southern end, flooding a meadow, while at the opposite end of the
lake the water mysteriously flowed away. Geologists did a hasty survey and
discovered that a large area of the park had developed an ominous bulge. This
was lifting up one end of the lake and causing water to run out at the other, as
would happen if yo lifted one side of a child's wading pool. By 1984, the whole
central region of the park--several dozen square miles--was more than three feet
higher than it had been in 1924, when the park was last formally surveyed. Then
in 1985, the whole of the central part of the park subsided by eight inches. It
now seems to be swelling again.
The geologists realized that only one
thing could cause this--a restless magma chamber. Yellowstone wasn't the site
of an ancient supervolcano; it was the site of an active one. It was also at
about this time that they were able to work out that the cycle of Yellowstone's
eruptions averaged one massive blow every 600,000 years. The last one,
interestingly enough, was 630,000 years ago. Yellowstone, it appears, is
due.
