Causes

I was reading The A-Unicornist’s blog by that swell chap otherwise known as Mike when I just had to stop. Mike had earlier pointed out to me some silly comment from the king of silly comments, Jack. But as hilarious as that comment was, Jack topped himself:

Actually, [William] Craig speaks primarily from a position of reason and logic; he doesn’t simply assert God, he considers certain premises that are logically valid – that causes are necessary for things to begin to exist

This is a common error that Christians make. The idea that we can apply the idea of cause and effect to the time prior to the Big Bang makes no sense. Cause is another way of describing force. Forces are products of the Universe that we know, of the Universe that we can understand. The whole reason why we say every force has an equal and opposite force is because we can deduce as much within our framework of laws. Once we go beyond that framework (that is, beyond the Universe), all the laws we know go out the window. We absolutely cannot say the Big Bang was caused by something on the basis of our knowledge of cause and effect – we are throwing out that very basis the moment we begin to talk about anything ‘prior’ to time.

Some people just aren’t smart enough for this stuff. Mike, fortunately, is. To put what I just said in his words:

Even if the universe had a beginning, Craig has no basis for assuming that a physical process such as causality exists outside of the universe – just because things within the observable universe require a cause does not mean the universe itself does.

Even if I’m wrong and all our laws remain intact ‘prior’ to the Big Bang, there still is no valid scientific basis for asserting so. Try again, theists.

2010: FTSOS in review, July to September

This is the third installment of the 2010 review of FTSOS. See the first two here and here.

July:
Some of the smaller posts I’ve made that I think deserve a little more attention are the ones where I emphasize that biology is all about shape. The article I wrote about the fight against HIV is one of those posts. Research earlier this year found at least one location on HIV molecules that remains a consistent shape between individual viruses. This is important because HIV’s ability to be differently shaped in different parts of a single body makes it difficult to combat.

I also wrote about the difference between atheists, new atheists, and anti-theists. One of the public relation problems for atheism is that it is viewed as a dirty word. People assume it means absolute certainty, and that is seen as arrogant. It’s ironic because belief in God usually comes with certainty and that isn’t seen as being so arrogant, but I digress. Atheism is not certainty. Furthermore, where it is involved in new atheism and anti-theism, atheism acts as a descriptive base; new atheism and anti-theism are normative positions.

One of my all-time favorite posts is the one about photolyase and cancer. Photolyase is a protein that captures light and uses two of its constituents (a single proton and single electron) to force contorted nucleotides back into place. It is not present in humans, but is common in plants and other animals, helping to keep their genes functioning properly. This may be one reason we’re more susceptible to cancer than many of our fellow organisms.

August:
This was a skimpy month for FTSOS. I was away on a couple vacations for the bulk of the month, so the majority of the posts were either from my “Thought of the day” series or they were pictures/YouTube videos. But for what was there, I couldn’t resist pointing out and expanding on a fantastic quote from the judge who said Prop 8 in California is unconstitutional. In his quote he said a ban on gays getting married fails to advance any rational cause. I compared that sentiment to the idea that the majority cannot be allowed to discriminate simply because it is the majority.

I also made a post about a website devoted to philosophical thought experiments. The thought experiment I chose to highlight was Judith Jarvis Thompson’s Trolley Problem. My big motivator was a recent discussion with another blogger who laughably claimed that the trolley experiment was merely a logistical exercise, not an exercise about morality. To date he is still the only person in the world to believe that.

I also went through a few theistic arguments that are obviously failures. The most notable in my mind is the argument that says everything has a cause, therefore the Universe had a cause. There are two major problems with this. First, then why not just say a sort of ‘exo-nature’ caused the Universe? There is no need for consciousness – in fact, that only makes the theistic argument less probable. Second, the whole basis for this argument rests in the idea that forces result in reactions. For instance, if I push a chair, that chair moves; I applied a force. This is basic physics. But the whole shebang of forces and equal and opposite reactions? We’re talking about the science of what we know that happens within the Universe. And all we know necessarily breaks down prior to the Big Bang. The First Cause argument cannot be used because it rests about an unwarranted extension of science. Religion abusing science? Crazy, I know.

September:
The beginning of September was just as skimpy as the end of August because I was still on vacation. But while I never gave a huge post on the subject, the defining moment of the month (and year and decade and…) for me was my hike of Kilimanjaro. I have started writing about it at this point – just not for FTSOS. But in lieu of that you can read the account of the journey from my fellow group member and current Facebook buddy Jim Hodgson.

I also gave a very lengthy post on why prostitution ought to be legal. No one seemed to care, but I put a lot of effort into, so I thought I would mention it here. Basically, we make the practice illegal because of our own discomfort with sex as a society. We also draw false correlations between it and other illegal activities: of course one illegal thing will bring with it other illegal things if it’s something people want. Finally, for the safety and health of all involved, it would be better to legalize and regulate prostitution than keep the old system we have now.

One of the most popular posts on FTSOS that people found via search engines was the one where I lamented low science and math scores in the United States. A lack of funding relative to other areas, hostility towards science, and a general anti-intellectual trend in the U.S. all contribute to the decline of America on the world stage in education.

Another lament was my post about the anti-vax crowd causing deaths. The fact is, people who advocate against vaccines or for made-up alternatives to vaccines are making the world a more dangerous place, making people sick and even causing deaths. Get vaccinated – and, if you have them, especially get your children vaccinated.

Once again I really want to highlight a fourth post here. In this case, it is the one I made about the Problem of Evil. This has forever been an issue that no Christian (or other relevant believer) has been able to resolve. If God is good and evil exists, then we need to answer why. Appealing to free will fails because while God is necessarily good, free will does not need to necessarily exist. In other words, God is required to be good; he is not required to create free will.

Expect October to December tomorrow.

The physics of how cats drink

An unfunded, seemingly just-for-fun study of how cats drink was recently carried out. Results show that they only touch their the surface of their tongues to the water. They use inertia to bring the water into their mouths, closing their jaws before the counter-acting force of gravity takes hold. The rate at which cats lap matters, which is a testament to evolution, of course. Interestingly, one model the researchers used predicted that larger cats would lap at slower rates. It turns out that that is true. But what I find interesting is utilization of social tools by the researchers to find their results.

“It occurred to me that there were some interesting biophysics behind that process,” Stocker said.

So he borrowed a high-speed video camera from his lab and taped Cutta Cutta drinking. With several other curious researchers along for the ride, Stocker analyzed those videos, along with video collected from Zoo New England and YouTube.com videos of lions, tigers and other big cats drinking.

“It seems to be that this is the first study in Science that uses YouTube as part of the research,” Stocker said.

The model also allowed the researchers to predict that larger cats would need to lap slower to strike a balance between the inertia and gravity of the water picked up by their tongues. Sure enough, the videos showed that lions and tigers lap less than 2 times per second, about half the rate of domestic cats.

YouTube, Facebook, Twitter…like it or not, they and their analogues are the future. (And personally, I like it.)
