Speaking of Pseudoscience: The Learning Channel and Pirahna

Almost forgot to mention a piece of pseudoscience I watched on The Learning Channel last night that had me ranting and raving about that channel. An otherwise informative documentary about piranha decided it wasn’t enough to dispel some of the myths about the fish, but also insisted on waxing poetically about why such myths were so resonant with human beings. In the process it managed to delve into pseudoscience.

It turns out that piranha aren’t quite as ferocious as early explorers such as Theodore Roosevelt claimed. They will attack pretty much any wounded creature to be sure, but the locals in and around the Amazon have adapted and so long as you don’t jump in the water with open wounds or when animals are being slaughtered in waterways, piranha attacks on human beings are extremely rare.

Anyway, the TLC program insisted that the reason human beings fear piranhas is that they don’t understand that the piranha’s function in the ecosystem is to clean up waste biological products (and the fish are extremely efficient at stripping corpses), but went further and claimed that scavenger species such as piranha or vultures don’t “live for themselves” but instead live simply to serve the ecosystem.

Give me a break. Piranha and vultures don’t serve some altruistic pseudo-end, but rather have adapted to take advantage of the fact that a good living can be had in quickly finding and consuming dead and dying animals. The show was also filled with all these pseudoscientific mentions of a “natural balance” which is a common sentiment but fallacious since there is never any such thing as balance — the environment is constantly in flux (one need only pick a specific region and present day ecosystem to that of the region’s ecosystem one million years ago to see the fallacy in the concept of “natural balance”).

Finally, the reason why people generally fear piranha isn’t much of a mystery. Even after seeing some of the early claims about piranha debunked, I’m still not so sure I’d want to be swimming in a river filled with fish that can strip a 140 pound animal down to bones in just a few minutes. That such a small fish can do so much violence so quickly is probably why people who don’t live with the fish on a daily basis fear them.

If You’re Going to Trash Talk

Brian Billick, coach of the Baltimore Ravens, defends his players’ trash talking saying,

Folks, when you go into the lion’s den, you don’t tippy-toe in. You carry a spear. You go in screaming like a banshee and you kick whatever door in and say, ‘where is the son of a bitch.’ If you go in any other way, you’re going to lose. Somebody has forgotten they had to fight their way up there last year.

Fine, but did Chris McAllister really need to say something as absurd as claiming that Eddie George “folded like a baby” after getting hit by Ray Lewis in an earlier game? And certainly if you’re going to dish it out, do not whine like a baby — as Billick did — because the Titans broadcast some of Billick’s comments on their Jumobtron just before the game (Billick had the nerve to suggest the action lacked class — which it did, but how would Billick recognize class if he saw it?)

The two things that annoy me most about sports these days are players who a) incessantly complain to referees about bad calls (it’
s part of the game, get over it) and b) spend more time trash talking than actually playing the game. It is as if it is no longer good enough to simply beat the opponent, but rather the opponent must be held in absolute contempt (and this attitude is highlighted most in the sports setting, but seems to be on that has spread throughout our society).

Tolkien Family Struggles

A lot of people (including me) are looking forward to the release of the Lord of the Rings films (assuming they don’t suck), but among those less than thrilled by the move is the Tolkien family. According to the Daily Telegraph (UK), the Tolkien family has been hounded by fans of the books who make themselves a nuisance, and have had no input on the films.

Of course the latter fact is due partly to the family’s opinion that the books should not be made into films. According to Richard Crawshaw of The Tolkien Society, “The Tolkien family are definitely not on board as far as the film is concerned.The general view is that there is not a need for it as it is a book of words and was not created to be a dramatic presentation.”

Father John Tolkein, one of JRR Tolkien’s sons, tells the Telegraph that, “The Tolkien family is under perpetual abuse of one kind or another. It goes on all the time. I am anticipating endless bother when the film actually comes out.”

2-3 gigabyte CD-RWs

At Comdex, TDK Electronics announced new CD-RW drives it will introduces later this year that will use multilevel recording to achieve much higher write speeds as well as larger capacity.

TDK claims that by using special media the drive will be able to write 2 gigabyte CD-Rs at 36X speed. TDK says it plans to scale the capacity up to 2.6 and then 3.2 gigabytes.

Will this fly? It might, depending on how much the drives cost. The cost-per-megabyte of the media is roughly equal to the cost of using current CD-Rs. If the drives cost roughly the same as high-end CD-RW drives, then this technology could be a viable CD-R replacement until the various rewriteable DVD efforts finally sort themselves out.

I use CD-R technology for back ups as well as archiving large multimedia files and the 650mb limit of current CD-R technology is really showing its age and the companies working on writeable DVD seem intent on delaying any real alternatives as long as possible. TDK’s drive isn’t a long term solution, but given that it may take another four or five years for cheap, standard DVD rewriters, this might be just the ticket.

Unsolvable FreeCell Starting Position

My wife is currently obssessed with FreeCell, the card puzzle game that ships with Windows. I’ve never been much into card games, but she can play FreeCell for hours.

So I was happy to point her to a web site that demonstrates there is at least one beginning FreeCell position which is impossible to solve in principle.

Edward Walsh on the Animal Enterprise Act

Several years ago, the United States created the Animal Enterprise Protection Act which was supposed to give courts and prosecutors more power to go after animal rights terrorists. The results have been less than stellar — only a single activist has ever been convicted under the law and there are now more terrorist acts than ever before, with the animal rights terrorists expanding into environmental issues. What is to be done?

Edward Walsh wrote an excellent review of the Animal Enterprise Protection Act for Lab Animal which is reprinted on the web site of the National Animal Interest Alliance (Walsh is a member of NAIA’s board of directors). While Walsh correctly perceives the Animal Enterprise Protection Act’s problems, I must respectfully disagree with a good portion of his analysis.

Why is the law so rarely invoked (i.e., almost never)? Walsh thinks it is because of confusion and loopholes within the law itself. I suspect there is a different dynamic at work — namely there is almost no political pressure to actually devote significant resources to exposing and prosecuting animal rights terrorists.

For this, the animal rights terrorists have largely themselves to thank. By carefully focusing exclusively on property crimes and avoiding injury or death to human beings, the Animal Liberation Front makes it difficult to justify the sort of massive investigation that has focused on extremist anti-abortion protesters who have frequently inflicted injuries and even committed murder. Moreover, by targeting property the vandals simultaneously create a great deal of positive outpourings from within the animal rights movement, while at the same time avoiding the sort of national negative press that might otherwise galvanize a public outcry against them.

Think about it — when was the last time an act of animal rights terrorism was included in a network news broadcast. The only recent instances I can think of were the attack on a laboratory at the University of Minnesota and the Earth Liberation Front’s arson in Colorado, neither of which created any sort of sustained outrage among the public.

Add to that mix the extreme difficulty in tracking down ALF and ELF terrorists. As the FBI has repeatedly said, political terrorists organized into small autonomous cells (as the ALF/ELF are) are the most difficult terrorists to catch. To date the terrorists who have been caught and prosecuted in the United States have been apprehended largely by accident (i.e. the terrorists made a serious mistake which brought them to the attention of police). Moreover, since there is no overarching ALF organization, but rather ALF is more like a brand name for animal rights terrorism, catching the perpetrator of a given act of terrorism only implicates maybe four or five other activists at most. The result is a minimal payoff for an extremely difficult task.

It is doubtful that, barring any such outcry from the public, police and prosecutors are going to devote significant resources to cracking down on animal rights terrorism. I suspect that it will, unfortunately, require the loss of life before the proper resources are allocated this important task. And, unfortunately, I think loss of life is becoming more and more likely.

Although they have been pretty successful at evading capture, however, animal rights terrorists have been singularly unsuccessful at creating political change in the United States. Frustration at their political impotence seems to be motivating the terrorists to take more daring and dramatic actions, and it is only a matter of time before there is a loss of life associated with these actions (there have, in fact, already been some close calls in the United States).

Once the political will is there, the Animal Enterprise Protection Act will be largely irrelevant. In fact it is hard to understand the point of having such an act in the first place except as a symbolic gesture. It would be far better off to simply charge animal rights terrorists with arson, burglary or what have you and ask judges to consider the political nature of their crimes during the sentencing phase.

One idea I oppose strongly is Walsh’s suggestion that there be a federal death penalty for animal rights terrorists who commit murder. It would be better to see a mandatory life without parole for people who commit acts of political murder.
