“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)

Creationism And False Dichotomies

Lim Say Liang at The Online Citizen has written an interesting article entitled "God sneaks into our classrooms" about how creationism has turned up in Singaporean schools.

I understand that creationism is formally not acceptable by the MOE, so I have nothing to add to that discussion from an education policy point of view.

From the scientific perspective, as Dr. John van Wyhe from Cambridge has emphasized in his recent talk, there has been no debate between evolution and creation since the 1870s.

Evolution - more specifically the part about common descent - has been accepted by the scientific community for over a hundred years.

However, debate about the details of evolution, such as its primary mechanism (eg. natural selection vs neutral drift) continues on today.

This sort of dispute is usually only interesting among specialists (may sound very boring to the general public) but will be gradually resolved in time with theory development and more experimental evidence.

On the other hand, the "Evolution vs Creation" culture war (and predominantly US culture at that) is a very tiresome and possibly neverending squabble that will persist as long as people, politics and money exist.

I won't go into the details of this - interested readers can just click the "evolution" tag to see my numerous articles (and even more numerous comments) regarding this topic.

Instead I would like to focus on a pair of comments posted in response to the TOC article -


1. New Renaissance on August 3rd, 2009 2.33 pm:

"In fact, what critical thinking can there be if only one side is presented?"

2. Jer Bear on August 3rd, 2009 3.09 pm @ New Renaissance:

"The other side of science is not fiction. The other side of science is science itself. One cannot disprove logic with fairy tales – therefore if you truly believe in teaching our children critical thinking, show them the thousands of articles written to refute certain scientific and mathematical explanations. Creationism or ‘intelligent design’ doesn’t count."


I think Jer Bear has addressed the New Renaissance's criticism quite well, but I would like to add my views on this matter.

I have observed that creationists like to think of science as if it was some kind of legal process and like to think of scientists as if they were lawyers.

In fact, creationist lawyers tend to think that their legal training makes up for their lack of scientific training.

Why is this so?

Simple.

Dichotomies, even false dichotomies, have a lot of SOCIAL POWER.

Remember ex-US president George W. Bush's infamous line: "Either you are with us, or you are with the terrorists."?

A legal system is an adversarial system. Either a suspect is innocent or guilty. There is no middle ground and thus no need to consider alternative explanations.

By proving your opponent wrong, a lawyer can confidently "prove" that she is right.

When deliberately forced upon science, this legalistic perspective crushes the whole scientific process into an oversimplified single dimension with two absolute outcomes: right or wrong.

That is why creationists spend practically all of their time attacking science rather than do actual research to support their views.

To their credit, they do understand the human psyche very well; the general public is easily impressed by outward appearance of authority, conviction and eloquence. As long as they can "prove" that the scientists are unsure, or hesitant, or not very good at public speaking, or too easily annoyed, creationists can then claim success.

This can be done without actually addressing the scientific content of the argument; indeed, it can be done without adequate understanding of the subject matter at all!

That is because creationists are not as interested in knowing what is factually correct as they are obsessed about being "proven" right. If they are "proved" to be right they can consolidate the social cohesion among fellow believers and also feel that they have the justification to impose their worldview on everyone else.

To directly address New Renaissance's comment that there can't be any critical thinking if only one side is presented, I would say:

"Are there only two sides in every debate? What critical thinking can there be if only two sides are presented?"

If the subject matter is creation stories, why not present a multicultural primer about creation stories throughout the world? If the focus is on anti-evolutionary views, why not include a section on animal spiritualism and Hare Krishna's "devolution" idea?

Creationists will never advocate multifactorial thinking, because it weakens their case that they can be "proved" right as long as their opponent is "proved" wrong. If there are ideas that don't support their case, they will cleverly package all of them together into a single opponent, even if those ideas don't have much in common with each other.

Eventually they will try to force an adversarial approach in order to maximize their social power.

Only the debates between "us" and "them" matters; disagreements between them "evolutionists" or disagreements between them "pagans" don't matter.

They are all wrong anyway... because my belief "proves" it.

Photo Gallery Thirteen

In a previous post, I briefly talked about how brand marketing has contributed towards the rising phenomena of tool worship and diminishing respect for professional training.

For this week's photo gallery I won't just talk the talk - I'll walk the walk!

Let me show you what a "toy camera" can do in competent hands.















Enter our unfortunate victim - the Lomo Fisheye 2.

Popular among fashionistas a couple of years back, it used to retail in arty bookstores for about a hundred bucks each. One look and you can tell that it's the sort of camera for the supercool to pose with and get totally bored with by the end of the week.

This example here is well kept, but has fallen onto hard times. I bought it used for $30 - "faulty" with an ailing internal flash (but I won't be needing it, as you shall soon see).

Incidentally, all the non-Nikon, non-Canon cameras in the above photo are second-hand. Poverty has its special way of compelling one to train hard - if you're rich then you can pay someone to do all the thinking and working for you!

That's not necessarily a bad thing, but I digress.

Time for a checklist!

The Fisheye 2 has:

1. No Megapixels (uses 35mm film).

2. No Autofocus (fixed from 30cm on to eternity).

3. No Variable Aperture (fixed f/8 plastic hole).

4. No Metering.

5. No Automatic Shutter Speed (fixed 1/100 sec and a bulb mode).

6. No Multicoated Lens (10mm fisheye lens which looks cheap and plasticky).

7. No LCD display (with no pixels by no pixels resolution).

8. Has Optical Viewfinder (Hah, bet your digicam doesn't have one of these!).

9. No Spare Batteries (you don't even need any if you don't use flash).

10. No Free Cleaning Kit (OK, now I'm getting carried away...).

Hmm... looks sufficiently devoid of modern camera features.

Passed!

In fact, somebody once said that:

"If you cut the bottom off a beer bottle and hold it in front of your standard lens you will take better pictures than the Lomo."

Ho ho ho... is that RRRRRRight?

Well, the Fisheye 2 was intended to be a chic fisheye camera for "Lomographers" to take wacky portraits with multicoloured flash and streaks of light everywhere.

But that's not what I had in mind for this little fellow.

Here's one of my pictures, straight out of the camera (or film processing shop actually):














Interesting.

But I prefer my scenery shots to be rectilinear rather than have fisheye distortion.

To do that, you don't even need to buy Photoshop. Just head over to TawbaWare and use their PTAssembler shareware to "de-fish" the distortion in a few quick steps.

And now for the finished product (cropped and exposure-corrected):

Not quite the bottom of a beer bottle huh?

Come to think of it, I could possibly make that work too...

Enjoy the rest of the photos!

You are thinking: "Hey, it's not the fact that the Lomo cost $30 that allows it to take nice scenery shots. It's the fact that it has a 10mm lens! The equipment DOES matter!"

Ha ha... you're right that every photographic tool has its strengths and weaknesses.

You generally can't use the Fisheye 2 for macro or sports photography.

But then again, if you know what you need for those applications, you wouldn't use the Lomo!

I think you understand what I'm saying now.

Solar Eclipse Over The Pacific

From my blog statistics I noticed that there has been a large spike of visitors to Fresh Brainz looking for information on the 22nd July solar eclipse.

Well, it has been rainy and overcast in Singapore so we can't see the Sun, but even if the sky was clear only about 6% of the solar disk is covered by the Moon from our location, so there isn't much to see.

Good thing that the Japanese TV company NHK has just uploaded this video of the eclipse relayed from a ship in the Pacific Ocean that is smack in the middle of the lunar shadow, providing a few minutes of totality.



Spectacular.

I like the fact that you can see planets in the daytime, for example Mercury as shown in this video. I for one have never seen Mercury directly before.

It is also interesting to see that while at totality, the surrounding horizon is still lit by the Sun, so it's sort of like a weird sunset all around them - except that the Sun is still straight up in the sky!

Pity that in the middle of the sea there aren't birds to sing their mis-timed evening song, which often occurs when totality happens over land.

"Militant Secularism" In The Netherlands

"Aggressive secularization" in the Netherlands leads to polygamy, euthanasia, infanticide and a suicide pill.

Oh noes, the Netherlands is DOOMED!



Wait a sec, this news report came from Fox News, which is the most "Fair and Balanced" news network in the USA.

Better go check some actual data...

**********

Divorce Demography
(crude divorce rate per 1,000 total population)

USA = 3.8 (2003)
Netherlands = 1.91 (2004)
Singapore = 0.78 (2004)

Prison Population
(per 100,000 total population)

USA = 701 (2002)
Singapore = 388 (2002)
Netherlands = 100 (2002)

Intentional Homicide
(per 100,000 total population)

USA = 5.8 (2008)
Netherlands = 0.97 (2002)
Singapore = 0.48 (2005)

Infant Mortality
(death per 1,000 live births)

USA = 6.3 (2005)
Netherlands = 4.7 (2005)
Singapore = 3.0 (2005)

Abortion
(per 1,000 women aged 15-44 years)

USA = 20.8 (2003)
Singapore = 12.6 (2004)
Netherlands = 10.4 (2004)

Suicide
(death per 100,000 total population)

USA = 11.1 (2005)
Singapore = 10.3 (2006)
Netherlands = 9.4 (2004)

**********

Wow, the USA is truly a world "leader" in all these areas!

Let's hope that the Netherlands (and Singapore too) will never follow its "lead" here.

Indeed, Fox News should be proud of their country and their own special style of reporting where the truth is always optional.

Pipette tip to Sandwalk.

Third Year

It's been three years down the road, and I would like to thank fellow Clearthought Singapore veterans and all my regular readers for staying on this channel.

I'll probably write a more substantial post a little later, because I went to the Darwin and Wallace talk in late June and took extensive notes, but right now my situation is not conducive to serious blogging.

So, to mark this third blogiversary I'll leave you with this little piece of Socratic dialogue, inspired by the post "don't need doctors anymore" at Angry Doc's site.

I hope you'll find it funny and interesting.

**********

Geordie: "Did you know that Steve McCurry, the photographer who took the famous 'Afghan Girl' photo came to Singapore and gave a talk at SMU?

Freddie: "Dang, I missed that. I went to John van Wyhe's talk at NUS instead. So, anything interesting?"

Geordie: "Somebody asked him what brand of camera he used. Ha ha, can you believe it?"

Freddie: "Heh, don't tell me it's the Nikon vs Canon dickfight again. Or is it Leica vs Zeiss?"

Geordie: "It's the Nikon vs Canon. I think that marketing hype is making people stupid. Nobody would ask a famous painter what brand of paintbrushes he used, so why should people care about the brand of camera that a famous photographer used? As long as the picture is focused and well-exposed would it have mattered if he used a disposable camera?"

Freddie: "I think that tool worship is common to people who don't understand or are not interested in the process. Perhaps the professionals themselves are contributing to this misunderstanding by making the process look too easy. The tool IS the profession. I can totally see it from that point of view."

Geordie: "What are you talking about? Are you saying that a camera can walk by itself to Afghanistan, endure the hardships of a wartorn environment, seek out interesting people, interact with them and produce a well-composed and expertly-timed shot?

Freddie: "Look, a camera is what takes the photos, right? If Steve McCurry didn't have a camera with him when he saw the Afghan Girl, the photo could never happen. You can consider him merely as a vehicle to bring the camera to the Afghan Girl and then press the shutter button. All he did was to travel to a remote place, turn some dials and push some buttons - the camera did all of the 'real' work."

Geordie: "Ha ha, that's a pretty twisted way to see it. The facts are the same but the emphasis is backwards. From such a view you can dismiss the photographer as an incidental, or even an irrelevant aspect of the photographic process!"

Freddie: "You don't need photographers any more, you just need an expensive brand name camera. The photographer only pushed a button! Anyone can push a button."

Geordie: "From that perspective you can pretty much dismiss the work of any professional. Teachers? Anyone can talk and write something on the whiteboard. The textbook IS education. Scientists? Anyone can push buttons and transfer liquids from one tube to another. The PCR machine IS research. Oh man..."

Freddie: "There you go."

Geordie: "Who could see it that way? Apart from a few strange people? I mean, that can't be a prevalent view, right?"

Freddie: "I suspect that it is more common than you think. To a society that is obsessed with results and performance indicators, most people can't be bothered about the process behind anything. What they want are results, now now now! Don't care how you do it. Just tell me what I want to hear."

Geordie: "But without the process you cannot have results."

Freddie: "But even with the process, you may not have results. So why care about the process? As long it produces a result that you like, it must be a 'good' process, whatever it is."

Geordie: "Ha ha, this must be a personality-dependent thing, because I don't understand how anyone can think that way. I suppose it is some kind of superduper mental shortcut. Good photo = expensive branded camera. Expensive = good. Cheap = lousy. Quick and easy."

Freddie: "Easy on the brain, but difficult on the wallet!"

Geordie: "Yeah, which reminds me of that neverending treadmill of earning and spending. If the price is the primary gauge of what is 'good' then people must keep buying more and more expensive stuff in order to feel a sense of improvement in their lives."

Freddie: "That's good news for the marketing people."

Geordie: "For the Nikon marketing people, Canon marketing people, or the disposable camera marketing people?"

Freddie: "Ha ha... suffice to say that happiness is not free, but it is surprisingly inexpensive.

Geordie: "It is meaningless to talk about the 'expense' of happiness. It's a process. You can't just stuff happiness into a bottle and slap a brand label on it."

Freddie: "Actually I think you can. And someone will pay real money for it."

Geordie: "Someone?"

Freddie: "Everyone."
