Probability Disproves Evolution, or Bees Can't Fly

Other people have coverred the probability arguments against evolution, already, but I'd like to cover it from the viewpoint of an aerospace engineer. Specifically, while reading this essay, I read the line, "The numbers just don’t match up — the universe would have to be much, much older than it is for random mutations to have produced that variety of life that we see on earth," with a link to this article.

I compare these types of arguments to the one that says bees can't fly. Most people have probably heard this before, but to explain it to those that haven't, if you take standard aerodynamic theory and do a rough back of the envelope calculation applying it to a bee, you could come up with the conclusion that bee's can't fly. For the size of their wings, and the speed that they move them at, the theory predicts a lift that would actually be less than the weight of the bee.

I'll be honest, I've never actually gone through this calculation. What's the point, when you know that bees can fly, and I'm not really concerned with designing bees, anyway. But supposing I did go through with the calculation and it did predict that bees couldn't fly, would it then make sense to say that, indeed, bees can't fly? Of course not. Observation tells us that bees fly - the error would be somewhere in my theory or calculations (applying steady state, high Reynolds number aerodynamics to a non-steady state, low Reynolds number application, for those interested), but that's exactly what these probability arguments are. Evolution has occured. There's enough evidence that it's not really a question. If you have a theory that says that evolution couldn't have occurred, either you've made a mistake in your calculations or assumptions, there's a problem with your theory, or perhaps, bees can't really fly, after all.

E-mail Forward- Allah or Jesus?

Just the other day, I received an e-mail forward of a story written by a Christian about a supposed exchange he had with a Muslim about the Islamic attitude towards infidels. The basic gist of the story was to illustrate how superior Christianity is compared to Islam, and how intolerant Muslims are of others. The entire e-mail, interspersed with my comments and corrected for the formatting errors that come about with multiple forwards, is available below the fold.

Science and Engineering Indicators 2006

The new NSF report on Science and Engineering Indicators 2006 has been released. Below are the results of the "Scientific Understanding" section. While there has been some improvement, the results are still depressing. The numbers in the table are the percentage of people that responded correctly, while the correct answer is listed in parentheses after the question.

  United States (2004) China (2001) South Korea (2004) Japan (2001) Malaysia (200) EU-25 (2005) Russia (2003)
Lasers work by focusing sound waves (False) 42 16 31 28 34 47 24

What Is the Value of Algebra?

Thanks to Pharyngula, Uncertain Principles, and Gene Expression over at Science Blogs for pointing this out.

Here's an interesting article in the Washington Post, written by some guy named Richard Cohen, who basically says that algebra is a worthless topic to most of the population, excluding the technical people who are going to need it for their careers. He argues that it shouldn't be a requirement for people to graduate from high school, which I think is just plain stupid.

Religion- The Good and the Bad

This is an excerpt from another entry on this blog. The original entry was so long that I wasn't sure people would read the whole thing, so I've decided to pull out the best parts into their own entries.

My wife and I recently went on a medical mission trip to Guatemala. Since it was a mission trip, pretty much everybody that went was a pretty devout Christian. And it seemed like a big part of the reason that many of these people went was to do God's work to help these people. So obviously, religion can inspire people to do good things. I think I had the most liberal interpretation of the Bible of anybody there (see my Bible Interpretation Essay), and that most of those people accepted the Bible as a divinely inspired book. Like I said, this is a topic I've been thinking a lot about, recently, so seeing all of these people going to Guatemala to help so many strangers made me think that maybe I'd been thinking too harshly about religious fundamentalism, if it creates good things like this. But then, towards the end of the trip, we learned about all the mudslides Hurricane Stan had caused in that country, and about a bad earthquake that had just hit Pakistan (and don't forget that Hurricane Katrina had just caused all of that devastation in New Orleans and the Gulf Coast), and it got the people to discussing those natural disasters. And what seemed to be the consensus was that the Bible talks about the end of the world coming, and these were just signs. And that really bothered me. It's a type of complacency - natural disasters happen, it's God's will so there's nothing we can do about it. What about global warming? We're screwing up the planet right now, and hurricane seasons are just going to get worse. Maybe this was just an anomolous year (random variability is going to make some years have more hurricanes than others), or maybe it was a symptom of global warming. Why not try to figure out the real reason - maybe we'll be able to change something to prevent this from happening in the future, or maybe we'll be able to predict these things better so that we'll be able to get people out of harm's way. But to just pass it off as God's will really irritates me.

So, after that conversation, it got my head back out of the clouds. Religion can inspire people to do good things, but I think that fundamentalism, or extremism in any sense, is bad. Let me repeat that, so that you don't skim through and miss it - the religious fundamentalism in our country right now is bad. You may say that you believe in Christ, but your actions are harmful. In the past, fundamentalism has lead to the Crusades, the Spanish Inquisition, all of the fighting in Ireland, and countless other evils. The bad things that have been done in the name of religious fundamentalism (not religion in general, but fundamentalism) more than outweight the good things that have come out of it. So, be religious, but don't abandon sense and reason.
