“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.” – Neil Armstrong (1930-2012)

God Is Made Of People

Just read an interesting comment regarding the ST news story "PhD holder now a cabby".

Posted by: opinion2009 at Wed Aug 19 17:51:07 SGT 2009

"Solomon said that men of understanding are not the only ones who gain riches: 'nor bread to the wise, nor riches to men of understanding; nor favour to men of skill, but time and chance happen to them all'.

Solomon is telling us that those who are better, wiser and stronger don't win the war, don't win the race, don't get the riches and don't win the favour.

But those who are in the right place at the right time win the race, and enjoy favour and success.

The only one who can put you in the right place at the right time is God.

We can try through self-effort to better position yourself for success by studying more, working harder and cultivating more strategic relationships.

You may end up being slightly faster, slightly stronger and more well-connected, but only God can put you in the right place at the right time and give you success.

There are people who find themselves in the wrong place at the wrong time. They are caught in a 'net' and they don't even know why.

For man also does not know his time: Like fish taken in a cruel net, like birds caught in a snare, so the sons of men are snared in an evil time, when it falls suddenly upon them.

We need God for 'Right Happenings'.

If we are honest and humble enough, we will acknowledge our need for God in our lives."

**********

So... God is somebody who gives you opportunities for success, and if you are "honest and humble enough", he will help you win wars, get $$$ and stuff like that.

But what if God has decided to put YOU in the wrong place at the wrong time?

And why would an all-loving, all-knowing and all-powerful God want to "help" some of his creations to become so rich and powerful that they would dominate and utterly devastate some of his other creations?

To an extraterrestrial observer, it seems like a "God" is actually a human social network that aggressively grows to accumulate material benefits to insiders while engaging in territorial conflicts with other "Gods".

Hmm... that reminds me of a classic movie "The Gods Must Be Crazy".



Narrator: "But the Gods have been careless; they had sent only one. And now for the first time in their lives, here was a thing which could not be shared because there was only one of it.

Suddenly everybody needed it most of the time; a thing they had never needed before became a necessity. An unfamiliar emotion began to stir. A feeling of wanting to own, of not wanting to share.

And other new things came. Anger, jealousy, hate and violence.

He was angry with the Gods.

He shouted: "Take back your thing, we don't want it. Look at the trouble it brought!"

But the Gods did not take it back.

He shouted: "You must be crazy to send us this thing, take it back!""

**********

Of course, the Gods will never take it back, because it was made by human beings.

To dispose of it, someone would have to take it to end of the Earth and throw it off, even if it meant that the person would have to walk for 20 days, perhaps 40.

Have you started walking yet?

How To Do It

Have you ever wondered why professionals in technical fields can become so grumpy and pessimistic?





Yes it would be sooooo nice if one simple, quick solution can be found for everything, such as "Just believe in success and you would achieve success!" or "Just vote for us and we'll guarantee job security and societal stability!" or "Just stop eating animals and you can prevent heart attacks, cancers and achieve world peace!" or "Just believe this book and everything will finally make sense when you attain eternal life!"

Pollyannas are especially annoying.

Not only because they keep shifting goalposts to make everything look cheery.

Not only because they dismiss the difficulties that technical people face with cute soundbites or the mere wave of a hand...

But most of all, because they are not the ones who have to take any real responsibility when their over-optimistic and simplistic plans end in utter failure.

It's never the "Vision" that is flawed!

It's always the workers "down there" - they are too complacent, they don't work hard enough, they are not resilient enough, they are not sufficiently hungry for "Success", they don't "believe" in the "Vision"...

The world is ruled by obscenely wealthy and well-connected people who are impressed by "The Secret" or "Who Moved My Cheese?" or "The Purpose Driven Life", while other people who make their opulent lifestyle even remotely possible with the blood and tears of their toil are marginalized and fed table scraps.

This is not a sustainable situation.

That's Not How You Play The Violin!

Here's a classically trained violinist, Alex Mitchell, playing the violin in a decidedly unclassical way...





Some people spend years and years learning from the establishment so that they can emulate them exactly and perpetuate the tradition forever.

Some other people spend years and years learning from the establishment so that they can evaluate them, transcend them, and sometimes even consign the useless bits of tradition into the giant trash heap of history.

As the great non-scientist/non-engineer Tay Ping Hui once said on TV:

"Scientists ask 'Why?'. Engineers ask 'Why not?'."

Actually, scientists MUST ask "Why not?" - at the minimum, to examine alternative explanations to their pet ideas to avoid getting shot down by their peers, to say nothing of scrutinizing established theories.

And did you think engineers have the luxury of asking "Why not" if scientists never asked "Why"?

Did you think that James Clerk Maxwell, Michael Faraday, Hendrik Lorentz and André-Marie Ampère were electrical engineers?

Did you think that Erwin Chargaff, Rosalind Franklin, Francis Crick and Jimmy Watson were biomedical engineers?

If the science stuff doesn't exist, then what would engineers engineer on?

A magic voodoo chant?

Hugh Laurie knows that playing a doctor on TV doesn't make you a doctor. Maybe Tay Ping Hui doesn't.

Censoring Myself Into Silence

This is it folks, I've totally run out of steam. Essentially, I've politically-corrected myself into silence. Fresh Brainz was supposed to be about science, which is a reliable method for discovering the truth. Unfortunately, the truth can be very offensive to many people in this world. They would cling on to their beliefs even when strong evidence indicates the contrary.

For too long I have been tasked to do impossible things. I don't considering focusing all your energy into doing impossible things as some admirable sign of tenacity or resilience. Especially when the evidence is clearly there.

I think that ordering other people to do impossible things and forcing them to believe in impossible things is a sign of megalomania, maybe sadism or even madness.

There is only so much one can do to hint or use subtle words to somewhat nudge you to plausibly tangentially consider some sort of issue. It is very tiring to bend over backwards to respect the feelings of everyone all the time.

That is not my style.

And so I have nothing left to say.

You Don't Have An Inbox...Yet???

I just tried to log in to my Hotmail account, but instead of the usual inbox I see this message:










I don't know what's going on - my account was working perfectly fine this morning.

If you click on the link provided and try to sign up for Windows Live Hotmail, you will get an online form to create a Windows Live ID (which you already have!).

If you try to fill the form using your own Hotmail address, it tells you that " ???@hotmail.com isn't available".

Spont-Ant-eous Generation

This Monday I'm going to talk about a phenomenon that doesn't annoy me as much as it mystifies me.

You know sometimes you are walking around doing your own thing when suddenly you feel an ant crawling up your hand?

You'd brush it off or kill it or whatever, and then the realization strikes you.

The ant had to come from somewhere.

But you were walking around.

In shorts.

Somehow that ant must have crawled up your leg completely unnoticed, scampered up your clothes, made its way onto your arm and scurried along for several centimetres more before you felt it on the back of your hand.

How did the ant make it so far without being detected?

I mean, you'd know it immediately when an ant crawls up your leg, right?













Unless...

Unless the ant mysteriously materializes...

*neeeeuuummmm*

... on the back of your hand, inst-Ant-aneously by an Intellig-Ant Designer.

Oh noes! I'm becoming a cre-Ant-ionist!

A Link Between Straits Times And Violence?

Sometimes, a news article produced by the mainstream media reveals more about the media itself than the incident it is trying to report.

Here is one such article (subscription required) :

A link between gaming and violence?

Experts say there is no direct link but in extreme cases, multiple risk factors are involved

By Jamie Ee Wen Wei
Mavis Toh
Huang Huifen

Three gamers were in the news last week for the wrong reasons. Two are dead and a third is in jail after they hurt themselves or others.

Is there a link between gaming and their aggressive or violent behaviour?

Studies by Iowa State University's Distinguished Professor Craig Anderson, one of the world's foremost scholars on media violence, show that playing violent video games causes people to think and act more aggressively, but he does not not believe playing video games will turn "normal 12-year-olds into school shooters".

Social psychologist Angeline Khoo, said that the link between violent computer games and aggressive behaviour is co-relational rather than direct.

Dr Khoo, who is the National Institute of Education's associate professor of the psychological studies academic group, explained: "When people read sensational news like this, they tend to think, it must be the evil game. But there are many people who play violent games and are perfectly normal."


What most people fail to understand is that physical violence, like stabbing, is only an extreme form of aggression. It rarely happens, she said.

More common manifestations of aggression are verbal, like raising voices or spurting vulgarities, she said. "The aggressive tendencies tends to be short-term. They can dissipate. For example, if you listen to soothing music after playing a violent game, you will calm down."

Experts agree that in extremely violent cases, there will usually be a convergence of multiple risk factors. There include gang involvement, anti-social parents and peers, substance abuse, poverty and media violence. Males are more at risk.

On the ground, psychiatrists and social workers are reporting more gaming-related problems among youths. At Touch Cyber Wellness and Sports, counsellors have seen more than 140 cyber-related cases in the past three years.

Dr Brian Yeo, a consultant psychiatrist at Mount Elizabeth Medical Centre, said he sees at least one patient daily who has gaming or Internet related issues.

"Some of them have avatars, and when their avatar dies or gets killed, they can become very angry, and in extreme cases, they may throw things or scream at their parents, or threaten to commit suicide."

Gamers are, however, upset that violent games have been fingered for the recent incidents.

Referring to the stabbing incident at Nanyang Technological University last week, Mr Nicholas Khoo, 31, co-founder of the Cybersports and Online Gaming Association, said: "Such incidents happen to a minority of gamers... In this incident, there could have been other reasons that led him to do it, so why was gaming blamed?"

Those interviewed also said they have not experienced any violent behaviour, although they said their relationships may have suffered.

Ms Sabrina Ong, 25, a blogger and avid gamer, said: "I don't become violent, but I tend to be more engrossed when I'm killing a character in shooting games like Left 4 Dead. I will shoo people away when they come and talk to me."

Technician Eddy Zhang, 28, said: "I became a bit reclusive. My girlfriend also broke up with me as she felt that I was spending more time playing games than with her."

Dr Khoo said studies have shown that parental involvement is vital in managing the violent effects of gaming.

"For instance, if someone utters a profanity in the game, the parent can tell the kid, we are not going to imitate this person's behaviour. There will at least be some guidance."

AsiaSoft, publisher of games like Maple Story, has created pop-up messages to remind gamers to take breaks. By the fourth hour, the gamers are asked to quit the game. Its spokesman said: "It's all about moderation."

David Hartanto Widjaja, 21

Online activities: A fan of the computer game World of Warcraft, the Indonesian student from Nanyang Technological University (NTU) spent as much as six hours a day in front of his PC.

What he did: He stabbed his lecturer, Associate Professor Chan Kap Luk, 45, in the lecturer's office last Monday.

What happened to him: Shortly after the attack, Mr Widjaja fell four floors to his death at the NTU campus.

Captain (Dr) Allan Ooi, 27

Online activities: The Singapore Armed Forces doctor was an avid Warcraft player who became one of the top 10 Warcraft players in Singapore, and was among the top 100 in the world.

What he did: He had been absent without official leave since last October, reportedly cutting off all contact with people close to him.

What happened to him: He was found dead in Melbourne last Tuesday.

Xia Yun, 19

Online activities: He played games from the multi-player online gaming site, AuditionSea.

What he did: Two years ago, he met a 10-year-old girl at the gaming site, and eight months later, they had sex.

What happened to him: He was charged with two counts of carnal connection. If he is not granted probation, he faces jail of up to five years and a fine of up to $10,000 for each charge.


**********

This is the most incredible Straits Times report I've read all year.

Based on all the expert opinions in the article itself, the heading should be "Experts say: no link between gaming and violent crime"

But yet it is "A link between gaming and violence?"

Eh???

The experts have clearly stated that the aggression displayed by engrossed gamers is short-term and there is only correlation data to show that violent computer games are "linked" to violent behaviour, not to say violent crime.

Correlation does not imply causation; this sort of "link" has no predictive value.

Let me illustrate this concept using an example given by Stanford professor Jerker Denrell.

The three men mentioned in the article not only played computer games regularly, but also brushed their teeth regularly.

Does it mean that toothbrushing is "linked" to violence?

To underscore how ridiculous this sort of insinuation is, let's rewrite some parts of the original article to reveal yet another apparently sinister, but utterly meaningless "link":

A link between newspaper-reading and violence?

Experts say there is no direct link but in extreme cases, multiple risk factors are involved

Three newspaper-readers were in the news last week for the wrong reasons. Two are dead and a third is in jail after they hurt themselves or others...

... Experts agree that in extremely violent cases, there will usually be a convergence of multiple risk factors. There include gang involvement, anti-social parents and peers, substance abuse, poverty and media violence. Males are more at risk.

Oh my!

Now I know why many people are so irate when they read our mainstream media articles - they become angry because of the violent news that is reported in the papers!

Or perhaps it's because the newspapers sometimes perform bizarre stunts, like trying to draw such a tenuous connection between three disparate cases and gaming.

To their credit, the Straits Times seemed to know that a single case cannot tell us much, and attempted to do a comparative analysis of these three cases.

However, a cursory look will reveal that even the correlation is not there:

Online activities:

1. David Widjaja = WOW (MMORPG with combat element - possibly violent)
2. Allan Ooi = WOW (MMORPG with combat element - possibly violent)
3. Xia Yun = AuditionSea (Online dancing game - violent???)

What they did and the aftermath:

1. David Widjaja = Apparently stabbed lecturer and committed suicide, investigation underway (violent)
2. Allan Ooi = AWOL, found dead under a bridge in Melbourne, investigation underway (violent???)
3. Xia Yun = Underaged sex with 10-year-old girl, charged in court (violent???)

Also, their interviews with various members of the public do not suggest any such correlation:

a. Nicholas Khoo: "Such incidents happen to a minority of gamers... could have been other reasons..." (disagreed with correlation)
b. Sabrina Ong: "I don't become more violent, but I tend to be more engrossed..." (disagreed with correlation, engrossed = violent???)
c. Eddy Zhang: "I became a bit reclusive. My girlfriend also broke up with me..." (reclusive = violent???)

What the hell is going on?

**********

At first, I could not believe that I was reading this sort of rubbish in our mainstream media.

On closer reading, I realized that practically nothing in this article supports the suspicion that gaming is linked to violent behaviour.

In fact, it almost seems as if the writers had set out to disprove this connection, but a subeditor decided to slap on a heading that is 180 degrees opposite to their assertion.

Which brings us to this crucial question that is glaringly omitted in the article:

Who is claiming a direct link between gaming and violence?

Experts don't claim this and the people interviewed don't claim this.

Is this report spurred by a massive discussion on online forums about the role of gaming in recent cases of violent crime (which I doubt because netizens tend to focus on the scholarship issue)?

Or did the Straits Times receive a huge influx of letters from concerned parents regarding gaming (which they have decided not to publish for some reason)?

Someone wanted to push the angle of computer games and violence.

Who?

Pretending To Believe

Here's a question for you:

If the United States of America is predominantly a nation of believers, how can they suffer from a "crisis of confidence"?

Indeed this enormous economic bucket of shit that we are going through right now is purely a social phenomenon, with no exogenous causative factors like poor harvest, infectious disease or a one-million-tonne meteor dropping in from outer space.

Everybody knows that this recession will eventually end.

Everybody knows that this recession provides a rare opportunity for huge gains.

Yet nobody seems to believe that she/he will be the one to emerge unscathed, thereby worsening the recession.

Sounds like a subsystem conflict of interest to me.

It's a positive feedback loop - the market index falls, which spooks some investors into pulling out causing the index to fall further, which then spooks more investors to pull out...

Some banks fall and other banks start to distrust each other and even their own customers. They make it harder for businesses to obtain credit, which causes businesses to close and the unemployment rate to rise, creating a climate of uncertainty which discourages consumer spending, causing even more businesses to close.

And thus the USA drags everybody screaming and kicking onto a slow train to hell.

It shouldn't have happened.

The USA is supposed to be a nation of patriots and believers. If they really believed that everything is going to work out fine because they have divine support, then it is impossible for the crisis to spiral into such depths.

That immediately brings to mind our old friend Pascal's Wager.

Pascal failed to take into account the possible negative consequences of pretending to "believe".

Unfortunately, the Gods have spoken and totally kicked his ass.

This economic disaster has made it abundantly clear that pretending to believe is NOT the same as really believing.

There are no two ways about this.

A true believer could not have made a run on the market. How can someone profess true faith but yet put in a stop loss, "just in case"?

Putting in a stop loss immediately indicates that the person has no faith in his decision at all.

Anyone can say that they believe in anything. Under normal conditions, this can be very beneficial to the person to help build social consensus and gain social rank.

But when the push comes to the shove, many of these people will simply abandon what they have pretended to believe and act upon what they really believe.

They will sell off all their shares, they will engage the services of a gay hooker, they will inject insulin into their bloodstream and they will use stem cell derived therapies to save their lives.

Hypocrisy? An integral aspect of human society.

This current crisis of confidence is a social problem, and social problems require social solutions.

As you can see, I'm a fan of double-edged swords (there are plenty of these in biological systems eg. sugar, glutamate, blood clotting pathway, tumour suppressor proteins...).

If greed was the problem that led us into this mess, then greed (of a different group of people) will be the solution to lead us out of it.

People who pretended to believe in growth while preparing for a decline were the source of this disaster; people who pretend to believe in decline while preparing for growth will be the source of economic recovery.

It's difficult for greed to go out of fashion - the consequences of lacking this driving force in a cruel, competitive society are severe. The benefits, on the other hand, are immense if not a little transient.

But life is transient and people have short memories.

In this way - greed, faith and hypocrisy will persist for many generations to come.

No More Bush!

This is not a brazilian wax advertisement...

Heh.

We live in a very odd world.

In this world:

1. If you rob 15 dollars from somebody, you will get three-and-a-half years jail.

If you rob billions of dollars from thousands of people, you will get million-dollar annual bonus.

2. If your small business fails, you will go bankrupt.

If your big bank fails, you will get a government bailout worth billions, and everyone except you will have to pay for it.

3. If you kill one person, you will be hanged.

If you kill hundreds of thousands, you will get generous retirement benefits, official fanfare and a helicopter to fly you home when it's all over.

Hmm...

Book me a ticket on the next space shuttle!*

Dangers Of Chelation Therapy

There is an ongoing discussion at The Online Citizen about alternative medicine and autism entitled "A Straits Times campaign against alternative therapies?"

For some unknown reason I keep getting an error message when I try to post my response.

I've tried numerous times but I only succeeded in getting a few words out. Thus, I've given up and will not be continuing the conversation there.

The discussion was with Mr. Richard Seah and Mr. John Yeo, both alternative medicine proponents.

This was my full reply -

Mr. Seah says:

"Several discussions are already available on http://www.autism-nutrition.com - eg studies on chelation, probiotics, vitamin B12, HBOT, neurofeedback, etc."

Since you don't want to pick a study to discuss, I'll pick one for you.

The key claim in chelation therapy is that mercury in vaccines is a significant cause of autism, and that drugs such as DMSA (which removes heavy metals such as mercury from the bloodstream) is an effective treatment for autism.

But do children with autism have higher levels of mercury in their blood, and/or difficulty excreting it?

Both you and Mr. Yeo have referenced this study:

Bradstreet J, Geier DA, Kartzinell JJ, Adams JB, Geier MR, 2003. A case-control study of mercury burden in children with Autism Spectrum Disorders. J.Am. Phys. Surg 8(3): 76-79

Original paper - http://www.jpands.org/vol8no3/geier.pdf

It is a single-blind retrospective study with 221 cases and 18 controls, which is a good sample size.

However, this study has some irregularities.

1. Instead of directly measuring mercury concentration in blood, the researchers measured the amount of mercury excreted in urine.

According to their results, even before DMSA treatment, children with autism have more than 3 times the amount of mercury in their urine than control subjects.

After a 3-day DMSA treatment, children with autism have six times the amount of mercury in their urine compared to controls!

However, both vaccinated and unvaccinated control subjects do not have elevated levels of mercury in their urine. This indicates that vaccination is not a direct cause of high mercury in urine.

The result only shows that for some unexplained reason, there is high mercury in the urine of autistic patients.

It could be due to higher mercury intake, or lower tissue retention, or even that control subjects are retaining more mercury in their bloodstream!

Without data from blood, we cannot conclude much from these results.

2. The quality of the data doesn't look good. Mean urinary mercury level is measured in micrograms per gram of creatinine units (mcg/g), and this is the data for children with autism:

Mercury level before treatment = 4.06 +/- 8.59 mcg/g

Mercury level after treatment = 6.42 +/- 12.69 mcg/g

The error bars are huge. The standard deviation is even larger than the mean itself, indicating that many children have no mercury in their urine at all.

Thus the results may be statistically significant, but not physiologically significant.

3. The paper contains a clause regarding two of the authors in this study:

"Potential conflict of interest: Dr. Mark Geier has been an expert witness and a consultant in cases involving adverse reactions to vaccines before the U.S. Vaccine Compensation Act and in civil litigation. David Geier has been a consultant in cases involving adverse reactions to vaccines before the U.S. Vaccine Compensation Act and in civil litigation."

I have read many scientific papers, probably as much as Mr. Yeo has, however, this is the first time I've come across such a statement in any paper.

This suggests that these authors have vested interests. To learn more about Dr. Mark Geier, here's a primer:

http://en.wikipedia.org/wiki/Mark_Geier

Dr. Geier is a controversial figure. In fact one of his recent papers to Autoimmunity Reviews has been retracted. To have a paper retracted is a serious setback for the reputation of a researcher.

http://www.bmj.com/cgi/content/full/334/7595/666

On top of this, although DMSA is approved for the treatment of mercury and lead poisoning, it can also remove essential minerals such as calcium and iron.

Thus DMSA has potentially serious side effects for developing children.

As Mr. Yeo has pointed out in his website (http://www.autism-nutrition.com/chelation-therapy.html) a study on DMSA funded by US NIH has been halted due to safety concerns.

In the light of all these facts, I would like to know on what basis does Mr. Seah and Mr. Yeo continue to support chelation therapy, and how do they intend to establish the safe dose of DMSA for their patients?

Six Words Yet A Whole Lifetime

Can you tell a story in six words?

According to a legend, acclaimed American novelist Ernest Hemingway was once challenged to write a story in only six words.

He wrote - “For sale: baby shoes, never worn.”

Here at Fresh Brainz, we are curious to know if you can write a story about yourself or about life in Singapore - using just six words.

Whether it is inspiring or depressing, thoughtful or shocking, England or Singlish - we would like to hear about it.

A few words can change everything.

Six And A Half Million

As the National Day approaches, it's a good time to look towards the future of our country.

The government is planning for a population size of 6.5 million people in about 40 years.

What's it like to live together with 6.5 million other people in a small island nation?

Here at Fresh Brainz, we are not content just with presenting numbers - we want to show you what having a population of 6.5 million people really means.

How much space does every person get?

The best way to visualize this is to use population density data.

Imagine a piece of land in Singapore that is exactly 1000 x 1000 metres in size.

That's one square kilometre.

Let's represent this area using an image file that's 1000 x 1000 pixels in size.

Inside this picture, we'll use one black pixel to represent one person.

For the ease of counting the people, let's ask them to stand close together in neat rows, similar to the marching contingents in the National Day Parade.

Back in 1961, the population density in Singapore was 2,540 people per sq km.

So, this was how the situation looked like (click picture for full size) :



















Plenty of space isn't it?

Well, that isn't an accurate reflection of the actual living space that you'd get, because most of the land area in Singapore is not used for residential purposes.

I can't find a land allocation chart for 1961, so I used the Year 2000 data (PDF file) as a guide.

The various land uses are represented as coloured bars that take up proportionally correct amounts of space in our one square kilometre.

Only about 12% of the total area is allocated for housing, which is represented as a white bar at the bottom of the picture:



















Clearly less space.

Still, you can see that our "pixel people" had enough room within the white bar to run around randomly and build single-storey homes to house their all tiny families.

Besides, there was also plenty of room for them to roam about in the other coloured bars, at work or at play.

Aww... all these happy peeps.



















Today, our population density has shot up to 6,489 people per sq km.

At this point in time, we have the third highest population density in the world.

As you can see, even though they are standing fairly close together, the people themselves are already occupying a significant chunk of space for housing.

If we assume that a family of four lives in a four-room flat of 90 sq metres each, then the 120,000 sq m living space only has enough room for 5,333 individuals - less than the population density.

Thus, the only way out is up - it has become impossible to fit all of our people without high-rise housing.



















Welcome to Singapore: population 6.5 million.

If there is no substantial increase in our land area and no change in land allocation patterns, then this is the situation in 2050.

With a population density of 9,286 people per sq km, standing room is starting to get scarce in the living space category. High-rise flats are an absolute necessity, and they will only get higher and higher.

Just imagine these people going to work in their 3-pixel long cars or 12-pixel long buses, filling up the space inside the grey bar.

Or how a weekend would look like when they go to the green bar for a picnic, or the yellow bar for a shopping spree.

Space would become very precious.

You are thinking: "Chay, not so bad what. If you spread out the little peeps throughout all the coloured bars, then there is still plenty of space to go around."

True... but it will still be much less space than 99.6% of the other countries in the world.

Just take any neighbouring country - say Malaysia, for example:



















Can you even see the people in this picture?

Seven Years Of Science

Today is sort of a special day for me, because exactly seven years ago, your humble narrator took his first fumbling steps into scientific research.

So far it has been... interesting.

I am aware that seven years' experience isn't much for a research career, but there are many young people who are just starting out and might like to have an idea of what doing science in Singapore is all about.

Instead of piling out stacks of boring details, I would like to illustrate my personal experience using one short, simple story.

It goes like this:

A long time ago, while studying in Canada, I went with a bunch of hostel mates to a dinner theatre.

It was the first time I had ever been to such an activity. You start with the dinner, which is a buffet-type spread, before the stage play begins.

While we were eating, one of the Canadian students pointed out a dish of wasabi next to a large plate of sushi.










Although I was familiar with sushi, I had never tasted wasabi before.

She said: "You're not going to like it - it's really hot."

Now that got me all worked up.

"Really hot?" I sneered.

Perhaps she had overlooked the simple fact that your humble narrator grew up in Singapore and had been thoroughly "trained" to eat some of the hottest and deadliest curries and chillies in the history of the Universe.

Why, I can chomp down one entire chilli padi directly without batting an eyelid, thank you very much.

Hot? HOT?!??

BWAHAHAHAHAHAHAR!

Weak-minded Canadians.

So I scooped up a big dollop of wasabi, plopped it onto my sushi and stuffed the whole thing into my mouth...

*FOOOOOOSH!*

The pain was immediate - a massive stinging explosion shot right up my nose, leaving me stunned in silence as tears slowly rolled down my cheeks.

Noticing my distressed expression, the concerned student asked:

"Are you OK? Is it hot?"

I weakly replied:

"Yeah... you're right... it is hot. I didn't know... wow... it is hot."

At that point in time, I wasn't struck as much by the inane imprecision of the English language as I was struck by the feeling of confusion and embarrassment.

How could I have felt so well-prepared, but still caught completely off-guard??!?

That, my dear readers, is what doing science feels like.

Love Your Thermocycler Today!

Mere words cannot describe the flood of emotions I get from seeing this video.





Heh... actors posing as "scientists".

Real scientists don't kiss a PCR machine (or any other lab device), nor do they have any reason to do so.

And their sentiment towards PCR is... to put it mildly... not love.

The only machine anyone should kiss and love is a Love Bot.

Counterintuitive Science: Importance Of Independent Verification

People like people who like them back.

As popular proverbs go: "A friend in need is a friend indeed", or "The best mirror is an old friend".

Wouldn't it be wonderful if everyone you knew became a good friend?

No more hate, negativity, animosity and conflict.

Pure bliss? Not quite.

Actually, if that really happened, you would be utterly fucked.

Why?!??

Two words.

Confirmation. Bias.

You see, there are too many people who think like this:

Human senses are fallible. There are light wavelengths we can't see, sound wavelengths we can't hear, chemicals we can't taste or smell, and even our sense of touch can be highly inaccurate. On top of that, they can become garbled or even deliberately fooled under certain conditions.

Scientists insist on only believing in things that can be physically observed. But what is the basis for this trust in our own senses? Don't you need "faith" to believe that human senses or human logic can actually decipher the true nature of reality?

Since science already takes this leap of "faith", why not abandon our imperfect human senses and use our "hearts" to perceive the ultimate truth instead?


To support this stand, an often repeated claim is that "you can't convince a completely colour-blind person that colour exists."



















Sure you can.

Let the people who claim the existence of "colour" select some distinctly-coloured objects, say "red" and "green" apples, which is indistinguishable to the colour-blind individual.

Then get them to sort the apples by colour.

If different people from different places in the world consistently and repeatedly pick the same specific apples to be "red" and others to be "green", you're on to something.

If animals can also see this distinction, we know that colour is not limited to human senses alone.

If people can demonstrate that different coloured objects consistently reflect a corresponding wavelength of light, which can be perceived and measured by a machine, we know that colour is not limited to living systems alone.

Even better - if a pair of goggles can be made which will represent these colours as different checkerboard patterns, then the colour-blind individual can directly convince herself that colours really exist.

Using such a device, she would be able to sort out all coloured objects, not just apples, in exactly the same way that people who can see colour would.

Of course, this is same principle behind machines like IR goggles or X-ray machines or ultrasonic detectors or carbon monoxide detectors.

Our fallible human senses cannot perceive these stimuli unaided, but no sane person would dismiss their existence.

Let's say that you were tasked to decontaminate a radioactive room. Would you put your trust on a Geiger counter (which was constructed using all too fallible human senses and logic), or would you trust your "heart" that the room is safe?

More importantly, would you base your trust on the Geiger counter on "faith" just because someone in authority told you it works, or would you personally test its accuracy against some known radioactive samples first, before even stepping into the room?

The bottom line is: a single piece of information from one sensory modality is indeed suspect, but if multiple lines of evidence from multiple independent sources all align towards the same result, then the conclusion is highly trustworthy.

This not only forms the basis of science, but also the basis of the criminal justice system for all modern democracies.

In science, this is how we determined that gravity and biological evolution are real phenomena.

In both cases, multiple lines of evidence using numerous experimental techniques, performed by independent (sometimes adversarial) research groups over many years of work consistently converge towards the same conclusion.

No faith is necessary; indeed, disbelief in gravity or biological evolution has no effect on the reality of either process.

However, there is a caveat to this method of gaining knowledge.

The key term is "independent".

You can't trust multiple sources when they are too closely related to one other.

For instance, if my vision and hearing were conveyed into my brain on the same nerve, and I suddenly see and hear something odd at the same time, I cannot count these experiences as two independent sources of information.

That is the reason why there is potential for big trouble if you are completely surrounded by like-minded and mutually-dependent friends who share your ideals and goals.

I'll give you a vivid illustration of this.

Imagine you are an avid mountain climber on your first attempt to conquer Mount Everest. You embark on this arduous journey with a number of good friends all of whom, like you, deeply desire to scale the summit.

Not long after you leave the base camp, you start getting nauseous and tired. Your heart is beating disturbingly fast, and you are beginning to throw up often.

You don't feel so good.

But your friends insist that you are doing fine and that everyone is going through the same difficulties.

Why would they say that? Maybe they have no idea how much pain you are experiencing. Maybe they simply want to encourage you to keep going. Maybe they want you to share the joy of conquering the peak together.

Or maybe you play an important role in the team and they really need you to stick around in order to succeed.

Whatever the case, you reach a camp at the halfway mark with many climbers from other teams. Your friends congratulate you for your efforts.

But a complete stranger notices your physical condition and casually remarks:

"You look like shit. Better turn back now or you'll be the next body count this season."

And then you come across a veteran climber from another team who says:

"Whoa... take it easy, man. I haven't seen another person who is as messed up as you in three years. Maybe you should consider turning back... I know I would."

Who would you trust?

Your friends? Or a couple of unrelated strangers who have nothing to lose or gain from your triumph or demise?

I think you can see that it is unwise to surround yourself with too many friends or yes-men, because they do not represent truly independent sources of information.

Their fates have become too closely intertwined with yours to dare voice out any dissenting views, even if they reflect the reality of the situation.

This may not appear to be an immediate problem for huge social groups which have enough people and resources to craft their own social realities, for example through self-affirmation and self-fulfilling prophesies.

However, cocooned within this semblance of diversity, the group incorrectly assumes that a consensus was reached via multiple independent sources, gradually losing touch with the wider reality.

It may continue to believe that everything is hunky-dory even though many lines of evidence from disinterested parties indicate that major problems lie ahead.

I cannot emphasize enough that conclusions reached using evidence from multiple sources are only trustworthy if the sources are really independent. This strategy serves to compensate for the fallibility of any single mode of information.

You are thinking: "Well, since human senses are imperfect, who cares if it's one human sense or fifty human senses. Why not depend on a single, perfect heart?"

Just a tiny problem there.

Human "hearts" are also imperfect.

If you have ever been heartbroken before, you will know how wrong a "heart" can be.

An Anti-Scientific Mind

An article written by British economist Robert Skidelsky is featured in the Straits Times today.

The header blurb on the Saturday section of the newspaper reads:

Cults of distortion

Environmental alarmists like Al Gore have infected science with a doomsday spirit that distorts debate.


That sounds provocative enough, but you wouldn't believe how shocking the actual article is.

You can read the full article from the Guardian website here.

Its original title is "The Apocalyptic Mind." The Straits Times has re-titled it "Beware Of Doom Merchants" and removed part of paragraph two, which I will discuss later.

But first, a quick summary of the article.

At first glance, it seems to be advocating skepticism against the media exaggeration of the negative effects of global warming, which might be counterproductive and lead to an economic disaster instead.

But more careful reading reveals the article to be a thinly-veiled and vicious attack on rational thought and the scientific enterprise.

Here at Fresh Brainz, we feel it's our responsibility to the public to encourage rational thinking and discourage obfuscation and disinformation.

Hence it is imperative that we scrutinize this article in great detail to highlight the numerous problems that it contains:

The Apocalyptic Mind

It was only to be expected that former US vice-president Al Gore would give this month's Burmese cyclone an apocalyptic twist. "Last year," he said, "a catastrophic storm hit Bangladesh. The year before, the strongest cyclone in more than 50 years hit China ... We're seeing the consequences that scientists have long predicted might be associated with continual global warming."

Surprisingly, Gore did not include the Asian tsunami of 2004, which claimed 225,000 lives. His not so subliminal message was that these natural catastrophes foreshadow the end of the world.


Right from the beginning, the author immediately conflates the term "apocalyptic", which is a religious term to describe prophesies revealed by divine revelation, with scientific prediction, which is developed using evidence.

In addition, a more accurate reading of Al Gore's message is that global warming will have severe consequences to humanity, not that it will somehow "foreshadow the end of the world".

It is one thing to claim that Gore was making an exaggeration to hammer home his point about global warming; it is entirely another to cast doubt on the essence of his message - that global warming is real and constitutes a significant threat to our future. More on this later.

For now, let's look at the second paragraph, especially the first sentence. Professor Skidelsky is "surprised" that Gore did not mention the Asian tsunami of 2004.

I am not surprised by this - because the tsunami was caused by an earthquake, a geological phenomenon. Al Gore may exaggerate but he certainly did not claim that global warming can cause earthquakes.

Is Prof. Skidelsky claiming that global warming can cause earthquakes?

However, I am surprised that the Straits Times chose to omit this sentence completely. It is likely that they noticed that this sentence alone would utterly undermine the credibility of the author to talk about climate change and thus they removed it.

Apocalyptic beliefs have always been part of the Christian tradition. They express the yearning for heaven on earth, when evil is destroyed and the good are saved.

In their classical religious form, such beliefs rely on signs and omens, like earthquakes and sunspots, which can be interpreted, by reference to biblical passages, as portending a great cataclysm and cleansing. Thus, apocalyptic moments are products of a sense of crisis: they can be triggered by wars and natural disasters.

Classical apocalyptic thinking is certainly alive and well, especially in America, where it feeds on Protestant fundamentalism, and is mass-marketed with all the resources of modern media. Circles close to the Bush administration, it is rumoured, take current distempers like terrorism as confirmation of biblical prophecies.

In secularised, pseudo-scientific form, apocalyptic thinking has also been at the core of revolutionary politics. In his latest book, Black Mass, the philosopher John Gray discusses how political doctrines like Marxism colonised the apocalyptic vision in prophesying the destruction of capitalism as the prelude to the socialist utopia. But political messianism was an offshoot of 19th-century optimism. With the collapse of optimism, contemporary apocalyptic belief lays more stress on catastrophe and less on utopia.

Clearly, the author likes to talk about the concept of apocalyptic thinking, devoting a number of paragraphs to describe its historical background. Unfortunately, he also enjoys using this concept as an over-extended analogy to everything else, eg. Marxism and science.

Skidelsky is claiming that biblical apocalyptic belief, Marxist vision of the destruction of capitalism and scientific predictions of environmental disaster are conceptually identical.

It boggles the mind what sort of detailed parallels you can draw regarding these three disparate fields to allow anyone to conclude that they are one and the same.

The only thing they have in common is: "before something really big happens, there are some symptoms."

So if somebody detects intensifying tremors and predicts that a volcano is about to erupt, is that an example of "apocalyptic belief"?

If I feel nauseous and predict that I might throw up soon, is that an example of "apocalyptic belief"?

For example, in his book Flat Earth News, the investigative journalist Nick Davies reminds us of the millennium bug panic. Newspapers everywhere carried stories predicting that computer systems would crash on January 1, 2000, causing much of the world to shut down. The subtext was familiar: those who live by technology will die by it.

It is certainly true that the Y2K problem became overhyped by the media, which underscores the importance of critical thinking and basic fact-checking in journalism. However, this does not mean that we should dismiss the possibility that obsolete computer codes can cause real problems.

In any case, what does this analogy have to do with global warming again?

Misreporting of science is now so routine that we hardly notice it. Much more serious is when science itself becomes infected by the apocalyptic spirit. Faith-based science seems a contradiction in terms, because the scientific worldview emerged as a challenge to religious superstition. But important scientific beliefs can now be said to be held religiously, rather than scientifically.

And so the attack on science starts. This entire paragraph is so absurd that it reads like bad satire.

The claim that science itself has become infected by the "apocalyptic spirit" is patently false.

Scientists don't believe that environmental disasters will destroy the evil, save the good and result in some sort of paradise - the negative effects of climate change will simply strike anyone who is unlucky enough to be at the wrong place, at the wrong time.

In fact, scientists very rarely even use the term "apocalyptic" in research publications: a quick search of the words "apocalyptic" or "apocalypse" in PubMed yields 101 articles, of which only one is remotely related to environmental science.

In striking contrast, the word "disaster" brings up 27,050 articles, "climate change" 4,573 articles and "climate disaster" 657 articles.

The only article of any sort that I have ever read that mentions "apocalyptic" so many times is this one by Skidelsky himself.

Also note that this article does not have a single reference to any actual scientific paper, indeed not even a brief mention of any environmental scientist or scientific organization at all.

And what in Justice Bao's name is "faith-based science"?

Science is based on evidence; faith is not. If the "faith" is based on evidence, it ceases to be faith.

Alternately, if the "science" is based on faith, it ceases to be science.

Scientific ideas are developed by testing hypotheses: acquiring physical evidence to support them.

Some people may find a scientific idea more convincing than others, so they would believe it more strongly, but I'm not sure what is the meaning of the phrase "important scientific beliefs can now be said to be held religiously, rather than scientifically".

Perhaps Skidelsky is trying to say that scientists should not be too confident of their ideas if there is insufficient evidence to support them. That is a valid point, but most scientists are well aware of this.

This brings us back to Al Gore and climate change. There is no doubt that the earth became warmer over the 20th century (by about 0.7 deg C), which most climate scientists attribute largely to human carbon dioxide emissions. If nothing is done to restrict such emissions, global temperature will rise between 1.8 and 4 deg over the next century. At some "tipping point", the world will be subject to floods and pestilence in classic apocalyptic fashion.

This is the second doomsday scenario of recent decades, the first being the Club of Rome's prediction in 1972 that the world would soon run out of natural resources. Both are "scientific," but their structure is the same as that of the Biblical story of the flood: human wickedness (in today's case, unbridled materialism) triggers the disastrous sequence, which it may already be too late to avert. Like Biblical prophecy, scientific doomsday stories seem impervious to refutation, and are constantly repackaged to feed the hunger for catastrophe.

I don't know if this is genuine confusion or deliberate obfuscation, but it is a mess.

The author insists (sarcastically?) that there is "no doubt" that the Earth is getting warmer and much of this is due to human activities. He thinks that the scientific prediction is that widespread floods and "pestilence" (again a religious term that is rarely used in science) will occur.

He then interjects the discussion with what he considers to be an example of an inaccurate scientific prediction: the Club of Rome's report in 1972. Ignoring the fact that the Club of Rome is think-tank, not a scientific organization and that they later gathered better data and improved their predictions - even if the Club of Rome is absolutely wrong, what does this tell us about global warming?

Nothing!

The tortured logic employed here is remarkable:

A. Some predictions I consider to be "scientific predictions" are wrong.

B. Therefore scientific predictions are likely wrong.


Well, since Newton was wrong about alchemy, Darwin was wrong about blended inheritance and Einstein was wrong about quantum theory, all of science must be inherently unreliable, right?

The author next claims that: "Like Biblical prophecy, scientific doomsday stories seem impervious to refutation, and are constantly repackaged to feed the hunger for catastrophe."

If this is true, maybe the environmental situation is really as bad as it is portrayed.

Alternatively, the appeal of doomsday stories could be mainly due to media hype rather than the scientific facts themselves. "Stories" may be impervious to refutation, but scientific ideas ought to be revised with improved data.

In any case, Skidelsky doesn't think that scientists are exempt from the responsibility of exaggeration:

Scientists argue that the media and politicians are responsible for exaggerating their findings as promises of salvation or warnings of retribution. But scientists themselves are partly responsible, because they have hardened uncertainties into probabilities, treated disputable propositions as matters of fact, and attacked dissent as heresy.

Excuse me sir, but what is the meaning of "hardened uncertainties into probabilities?"

A probability of 0.9999999999 is pretty hard while a probability of 0.0000000001 is not quite so hard.

Is the author trying to say that by switching a descriptive term (uncertainty vs probability) you can transform eg. a feather pillow into a brick wall?

And, if there are disputable propositions that bother him so much, why not discuss the scientific details in the article, so that we can examine them?

Scientists are notoriously loath to jettison conclusions reached by approved scientific methods, however faulty. But their intolerance of dissent is hugely magnified when they see themselves as captains in the salvationist army, dedicated to purging the world of evil habits.

Conclusions reached via the scientific process are scientific conclusions. These conclusions are supported by the best evidence and the most accurate models available at the time, rigorously checked for precision and reliability.

Of course scientists are not supposed to "jettison conclusions" on the basis of their personal convictions, no matter how counterintuitive the results may be.

That would be an act of professional misconduct.

If Professor Skidelsky personally believes that what he considers as "approved scientific methods" (testable predictions? repeatability? peer review? WHAT?!??) to be so fatally flawed, then my question for him would be:

What other method would give you better results?

As for his complaint about intolerance of dissent, I can't speak for all scientists, but here's an alternative explanation: I'm quite sure people in general would be annoyed if they were confronted with unsubstantiated arguments and baseless accusations that they are "intolerant".

Today it is the west that foists an apocalyptic imagination on the rest of the world. Perhaps we should be looking to China and India for answers about how to address environmental damage, instead of using climate change as a pretext to deprive them of what we already have. How do the Chinese feel about their newfound materialism? Do they have an intellectual structure with which to make sense of it?

Without missing a beat, Skidelsky over-generalizes his apocalyptic thinking to all the Western nations. Perhaps he feels qualified to represent all of them as the "captain of their salvationist army".

Well, he is probably right that a whole new generation of environmental solutions, including economically viable green technologies, will arise from Asia.

I can't speculate on the intellectual structure that will be employed to achieve this, but if China and India succeeds in this endeavour, I think it won't be due to the efforts of people like him, but in spite of them.

The best antidote to the doom merchants is scepticism. We must be willing to take uncertainty seriously. Climate change is a fact. But apocalyptic thinking distorts the scientific debate and makes it harder to explain the causes and consequences of this fact, which in turn makes it harder to know how to deal with it.

OK, so skepticism is good and Skidelsky accepts that climate change is a fact. Apocalyptic thinking is bad (you don't say!) because it distorts the scientific debate.

Although the consequences of climate change are real, the extent of the problem is debatable - he appears to have taken an entirely reasonable stand.

The danger is that we become so infected with the apocalyptic virus that we end up creating a real catastrophe - the meltdown of our economies and lifestyles - in order to avoid an imaginary one. In short, while a religious attitude of mind deserves the highest respect, we should resist the re-conquest by religion of matters that should be the concern of science.

Wait a sec, now Skidelsky says that global warming is imaginary and we should carry on with our lifestyles as if nothing has changed.

What is his real stand?

Does he even have a stand?

In addition, he turns 180 degrees around from saying that "apocalyptic thinking distorts science" to "a religious attitude of mind deserves the highest respect" in the space of just one sentence!

So is apocalyptic thinking good or bad?

Does he even care?

**********

To sum up, this is the most appalling article I have read this year.

At Fresh Brainz, we are in awe of how all these over-extended analogies, tortured reasoning, vacuous arguments and self-contradictions can possibly fit into one article.

Despite this, we strongly agree with the last line in Professor Skidelsky's article:

We should resist the re-conquest by religion of matters that should be the concern of science.

Global warming is a scientific matter and we must resist the attempts by anti-scientific individuals, such as Prof. Skidelsky himself, to dismiss a real problem as an "imaginary catastrophe".

Damned Materialistic Scientists

One thing I have never really understood is how the term "materialism" came to have such a negative connotation in society nowadays, both in the East and the West.

Considering how much of the high quality of life in affluent countries is made possible by market economies.

Oddly enough, it seems that people who are the most driven by material wealth are also the ones most likely to disavow or downplay the importance of this powerful motivating force.

"It's not about the money, it's about passion in investment."

Man, there's widespread denial going on.

What is especially annoying is how some people lump the words "materialist" and "scientist" together as some kind of insult.

"Damned materialistic scientists refuse to accept the possibility of supernatural explanations!"

Superb rhetoric, by the way - in one blunt blow, it denigrates the scientific endeavour by insinuating that scientists are dogmatic and small-minded money-worshippers.

Here at Fresh Brainz, we examine this dubious statement and arrive at a few surprising insights.

Prepare to bend your mind around it ...

1. Science is not restricted to "natural" phenomena or explanations

This is an easy one.

There is simply no hard (or permanent) boundary between natural and supernatural phenomena.

A long time ago, many observations had supernatural explanations.

The Sun was supposedly pulled across the sky behind the chariot of a sun god. Diseases were caused by evil spirits. Bizarre behaviours were the result of demonic possession.

They were supernatural phenomena.

Gradually, as the scientific process was employed to investigate them, naturalistic theories were developed which replaced the old explanations. Eventually, these phenomena became redefined as natural.

You are thinking: "What's so great about natural explanations? Why not just keep the old supernatural explanations if people love them so much?"

Dude, natural explanations are far superior to supernatural versions.

Not convinced?

Consider this - if a deity was personally responsible for hauling the Sun across the sky, then you would have a lot of things to worry about:

What if he wakes up late one day? What if the chariot breaks and the Sun falls out of the sky? What if the horses stop running and the Sun gets stuck in the middle of the sky? What if he is angry at the mortals for some reason? Do we need to build a statue to appease him? How many times must we worship him a week? What kind of animal sacrifice would please him?...

... and so on.

Supernatural explanations cannot generate testable predictions, which means that you will always be at the mercy of some unknowable power.

In contrast, a natural explanation such as the heliocentric theory is not only simpler and more elegant, but also fits the observations much better, generates reliable predictions and serves as the basis for future knowledge.

No need to build a statue or sacrifice a goat.

Even so, that doesn't mean that naturalistic explanations must be any less exotic than supernatural ones.

I mean, the Solar System is governed by invisible gravitational forces that travel at the speed of light? That almost sounds more "supernatural" than a sun god!

Nevertheless the theory predicts the exact second that sunrise and sunset occurs, as well as other accurate forecasts for solar eclipses, lunar eclipses and the movement of the planets.

This incredible achievement had an immense impact on how people live and view their own place in the Universe, replacing a cloud of fear and superstition with clarity, understanding and confidence.

Notice that the heliocentric theory cannot DISPROVE the possibility that a supernatural deity is personally dragging the Sun around the Earth while simultaneously planting fake evidence that the Earth orbits the sun.

It just renders such a belief unnecessary and irrelevant.

2. Material explanations do not preclude emergent properties

Here's an often asked question: "If human beings evolved from monkeys, then why shouldn't we act like monkeys? Why do we need to care about morals?"

Indeed, if we evolved from "lightning striking a mud puddle", why don't we act like mud puddles?

To illustrate just how ridiculous such a question is, let me bring up a simple example:

This is a pyramid.

A pyramid has a square base, triangular faces and an apex on top.

Due to the fact that the pyramid has a wide base and narrow top, it is a stable 3D shape.

Of course, no "indivisible" pyramid exists in reality, so here are some example of physical pyramids.



















This is a pyramid made of beer cans.

It has a square base, four triangular faces and an apex on top.

But none of the components have a square base or an apex! Beer cans have a cylindrical shape.

So how can a pyramid be made from beer cans?















This is a pyramid (more accurately a tetrahedron) made of marbles.

Marbles don't have any base or apex. They are completely round.

How can a pyramid be made from marbles?















This is a pyramid made of seashells.

Seashells have an irregular, complex shape. Not quite sure which part of the shape can be considered a base or apex.

How can a pyramid be made from seashells?

Although all these pyramids are made from different components with different properties, the emergent properties of each complete structure are the same.

This is mainly due to the organization and interaction of the components, and not so much on their individual characteristics.

Thus, just because living systems are made from tiny molecules, doesn't mean that life is a simple additive result of molecular properties. Complex systems have emergent properties at each successive organizational level.

Similarly, just because human beings evolved from other species of animal in the past, doesn't mean that we are compelled to follow their social rules. Our own morals are socio-emergent properties that arise from interactions between human beings at the societal level.

There is no need to posit a supernatural origin for our social behaviour.

In addition, being made of molecules doesn't reduce our status down to a mere bag of molecules nor does being evolved from bacteria eons ago somehow reduce our dignity to that of bacteria.

In the past, it may be excusable to confuse materialism with greedy reductionism, but today with increasing emphasis in organizational principles in science (eg. computational neuroscience) it is difficult to comprehend why there are still so many people who insist that a material explanation is insufficient to account for life.

Maybe I should invent a new word, called "process-ism" or "functionism" instead of "materialism" to emphasize the importance of the organization and interaction of the components, rather than the materials themselves.

After all, once you understand how the system works, you can swap the components around like nobody's business and it will still function properly.

















The system "transcends" its material make-up, but cannot exist without it.

3. Money is virtual, not "material"

The problem with using the term "materialism" is that it has two distinct meanings:

a) The philosophical theory that matter is the only reality.
b) A desire for wealth and material possessions with little interest in ethical or spiritual matters.

So far the focus of the discussion has been on the first definition.

Now, just for fun, let's examine the second definition of materialism.

Money has always been used as the poster child for materialism.

However, when you think about it - unless you collect coins and banknotes as a hobby, money is not in fact a type of material, but a virtual concept!

I recall watching a documentary where the CEO of Linden Labs (creator of Second Life) said that "money is the first form of virtual reality in human society".

And that is quite true.

Unlike "real" material possessions like computers or luxury watches or sports cars, the value of money is not in its intrinsic function.

It is only a placeholder - a piece of paper or metal given value by governmental authority and social consensus.

Today, money is evolving towards a form of pure information due to the popularity of computer-based banking and finance. Increasingly, it has become bits stored on a hard disk, magically transforming into goods and services upon demand.

So, does this mean that only the people who buy lots of actual material merchandise are "materialists" whereas misers who hoard gobs of money in virtual form are not?

What about people who treat money as a tool for safeguarding their freedom, rather than as a means of buying stuff? Are they "materialists"?

Hmm ...

Maybe money is a kind of "real virtuality" like computer games or human consciousness, which is why people are naturally attracted to it.

You are thinking: "Yeah whatever. Money might be virtual but it isn't abstract. Just stand in front of a vending machine with an empty stomach and an empty pocket and you'll immediately know how concrete it is."

Dude, that was brilliant.
