Thought of the day

February 1, 2010

This is a quote from the X-Files tv show, from years gone by, that I was reminded of recently. It is of course a reference to Forest Gump.

Life is like a box of chocolates. A cheap, thoughtless, perfunctory gift that nobody ever asks for. Unreturnable, because all you get back is another box of chocolates. You’re stuck with this undefinable whipped-mint crap that you mindlessly wolf down when there’s nothing else left to eat. Sure, once in a while, there’s a peanut butter cup, or an English toffee. But they’re gone too fast, the taste is fleeting. So you end up with nothing but broken bits, filled with hardened jelly and teeth-crunching nuts, and if you’re desperate enough to eat those, all you’ve got left is an empty box – filled with useless, brown paper wrappers. 


Biology in Avatar

January 24, 2010

I recently saw the film Avatar. Despite the rehashed plot (think Dances with Wolves), I enjoyed the film immensely for its visual impact, effects, action, and of course way-cool 3D. I also liked much of the biology in the film. I thougt the creatures and plant life of Pandora were very plausible and creative. The idea of an ecology based on interconnected neural networks is an interesting one, and is conceivable if electrochemical signalling evolved early in the evolution of life on Pandora.

But there is one thing that bugged me a little.

The designers put a lot of effort into the consistency of the biology. The animals seem to share the hexapedal body plan, paired neural appendage, and clavicular respiratory organs openings. Also, many have a smaller, second eye on each side. The Na’vi people, however, do not. The neural appendage clearly indicates they evolved on Pandora, which means they share common ancestry with the other animals. And yet they have only four limbs, no second pair of eyes, and they have a nose.

Okay, I get that from a concept standpoint the humanoid appearance makes them a) easier to relate to from an audience standpoint, and b) has that added “just ’cause they look human don’t mean they are human” kick. I may be quibbling, but to go through the degree of design that they did and not even give the Na’vi anatomical vestiges – a second bump on the shoulder, depressions beside the eye and beside the collar bone, something to indicate common ancestry, seems to me like a significant oversight in an otherwise stunning production.


DNFTT

January 17, 2010

For the six of you who don’t know, here is the definition of a troll from Wikipedia:

In Internet slang, a troll is someone who posts inflammatory, extraneous, or off-topic messages in an online community, such as an online discussion forum, chat room or blog, with the primary intent of provoking other users into an emotional response or of otherwise disrupting normal on-topic discussion.

And from Urban Dictionary:

One who posts a deliberately provocative message to a newsgroup or message board with the intention of causing maximum disruption and argument Essentially, a troll is someone who jumps into discussions to generate a flurry of responses – usually aggrevated – and seems to feed off the responses, often interjecting additional comments to try to stimulate further aggrevation. They consider the responses recognition and affirmation, so the more responses they get, the happier they are, even if those responses are scathing.

Anyone who frequents online fora has come across such behaviour. But it is not always clear whether we are dealing with a troll, per se, or just an idiot. The first question is, must a troll be intentionally trolling? If a person (or person-like organism) behaves like a troll and performs troll-like actions because of some firm, intrinsic belief or a genuine desire to try to convert others to their point of view, are they a troll? Can one be an inadvertant troll?

To answer that, I suggest putting it through the Duck Test. If it looks like a duck, and quacks like a duck, well, for all intents an purposes it is a duck. Or a merganser, which is close enough.

The second question is, must a troll necessarily be a commenter, or can trolling be generated in a post itself? Typically, trolls toss inflammatory comments into an otherwise normal discussion. However, if someone takes the time to generate a full-blown post that accomplishes the same result – aggrevation and a flurry of responses – then the result is the same. An ambitious troll, but a troll nonetheless.

And so, with these criteria considered, I think it is perfectly fair to say that Dawkinswatch fits the definition of a troll.

Consider: He has little imagination, mostly just rehashing the twaddle of others. His posts are often inflammatory, accusing celebrities of devil worship, and accusing those who don’t share his particular brand of YEC fundamentalism of ignorance, stupidity, insanity, and immorality. He repeats himself despite contrary evidence, and asks for information just provided. He misses the point of most counter arguments. The more his arguments are shown to be baseless, the more he writes. And best of all, he frequently responds to legitimate arguments with non-sequiters of epic proportion.

Dawkinswatch, whether intentional or not, is a troll.
And there is really only one response.
Do Not Feed the Troll (DNFTT).

An animated version of Tim Minchin’s poem Storm is in the works. In the meantime, for those of you unfamiliar with it, here is the live version in all its glory  a text version, as the live version has been pulled.


More on global warming and the hacked emails

December 5, 2009

New Scientist has published a thorough overview of global warming, and why the hacked emails are largely irrelevant.

The leaking of emails and other documents from the Climate Research Unit (CRU) at the University of East Anglia, UK, has led to a media and political storm. The affair is being portrayed as a scandal that undermines the science behind climate change. It is no such thing, and here’s why.

We can be 100 per cent sure the world is getting warmer

A Wandering Moral Compass

December 3, 2009

One of the main arguments by young-earth creationists against evolution actually has nothing to do with either creation or evolution.  The argumant goes like this:

  • With evolution there is no need for a god.
  • The study of evolution therefore leads to atheism.
  • Since God is the arbiter of right and wrong, disbelief in God removes any perceived need for a moral filter a person might have.
  • Therefore, evolution is wrong because it leads to amorality.

While this is just so wrong on so many levels – akin to “Your research is completely false because I dislike your sweater” – there is something even more. It turns out that it is belief in god that leads to a wandering moral compass.

A recent study, described in New Scientist, shows that people map their own beliefs on what they think God believes. In other words, people presume God’s beliefs based on their own, rather than the other way around. Thus, as people’s beliefs change, so does their presumption of God’s beliefs.

 This means that there is no absolute and permanent recognition of what God believes, and thus there is no definitive moral compass imposed by the Almighty. Even worse, it says that whatever a person believes, if they are a believer, they will tend to think that their personal beliefs are shared by God, and therefore just.

As an argument, this does not, of course, demonstrate the validity of evolution (there is plenty of that elsewhere) any more than the original argument refutes it. It does, however, suggest that creationists should not throw stones. Or, to take it a step further, maybe it suggests that evolution should be taught because it removes the wandering moral compass, leading to greater morality. 

I’m just sayin’.


On East Anglia CRU’s hacked files

November 24, 2009

One scientific issue that may polarize people even more than evolution is anthropogenic global warming – the idea that CO2 from human activity is throwing off the natural balance, leading to significant, possibly irreversible,  greenhouse warming.

The proponents argue that there is significant evidence that CO2 levels have risen faster since industrialization than any time in the geologic record, and that the temperature and climate profile are consistent with rising temperatures induced by GHG’s. Increased energy in the atmosphere could not only lead to rising temperatures, but increased storm activity, melting ice caps, increasing sea levels, and ultimately economic disaster and the displacement of a significant portion of humanity.

The naysayers claim that the evidence is inconclusive (at best) or nonexistant (at worst). Further, they argue that Global Warming Propagandists (or “Warmers”) are threatening global economic stability for personal agenda, or even personal gain.

Significant fuel for this dispute was tossed into the flames this week with the “hacking” of emails and data files from the University of East Anglia Climate Reasearch Unit (CRU). Selected exerpts mention using “tricks” in the data, and “hiding” a decline in temperatures. Sites sharing this information – purporting to blow the whistle – go over the top with rhetoric about how ALL of climate research from “warmers” and alarmists can immediately be dismissed because of clear evidence of fraud and conspiracy.

Folks, chill.

This leak of private information in no way informs the debate. None. This is private communication, out of context, taken illegally. Third party interpretation and trumpeting is not even remotely reliable. Why? because those spreading the files have as much of an agenda as they purport the “warmists” to have. Innuendo and quote mining is not the way to win an argument upon which the future of humanity may rest. Sorry, but it’s not.

There are legitimate scientific questions still outstanding about climate change, because we don’t have a control earth to compare with. But the venue to resolve those problems is in the scientific literature, not FOX news. But, you cry, how can we trust the Warmist conspirators to allow unbiased peer review? Well, the criminal responsible for stealing and publishing the CRU files has seen to that. Climate research will now undergo an extra-thorough level of review, simply because everyone is watching. Carefully. Of course, that goes for all climate research, including that indicating minimal anthropogenic effect. So perhaps the theft will have a beneficial effect in that scrutiny will be even more thorough (not that it wasn’t before), but perhaps it will also delay important research.

In the end, I suspect nothing useful will come from the stolen files, but the potential for setbacks to important research is significant.


Science. It works.

Not as dumb as (you think) they look

November 21, 2009

A common argument against past human achievements – that they are either fraudulent, or the result of superhuman intervention – is the supposed impossibility of those achievements. The Nazca lines, the pyramids, astronmical discoveries, Stonehenge etc.  A whole field of woo, starting with von Däniken’s Chariots of the Gods? is based on the premise that past humans could not have been clever enough to do things, simply because we, today, don’t know exactly how they did it.

The argument devolves to “I can’t figure it out, so how could they figure it out?” or, more simply “Nobody in the past could possibly be smarter than me.”

That’s why I love this TED video. It shows a simple device invented millenia ago, but I would wager far fewer than 1% of people alive today – especially in the developed world – could figure out how to make one.


Newly discovered mutation protects against prion disease

November 19, 2009

A recent article in New Scientist is a perfect illustration of how mutations can be beneficial, how beneficial genes can spread rapidly, and how humans are still evolving.

The mutation is a single amino acid change that appears to provide complete resistance to kuru, a prion disease similar to CJD or mad cow disease. Kuru was passed on through ritual cannibalism in Papua New Guinea, when family members ate the brain of the dead out of respect. Of course, once the disease began to spread, more funerals would lead to more cannibalism, which lead to more disease.

The protective gene is thought to have arisen within the last 200 years, and spread rapidly due to the selective pressure of kuru on the community.
