Dr. George Yancey lectures on anti-Christian bias in academia, and beyond

2 Comments

My good friend Wes posted this 28-minute lecture.

If you watch 5 minutes, then you’ll definitely stay and watch the whole thing. It’s fascinating.

Details:

Join Dr. George Yancey in an in depth discussion of the bias taking place within academia against religion in general, but more specifically Christianity. Within the discussion Dr.Yancey uses brief explanations of his previous book, Compromising Scholarship and many other excerpts of his past research as well as his forthcoming research to give us a new viewpoint on academia and religion.

I found a quick description of Dr. Yancey’s work in this New York Times article from July 2011.

It says:

Republican scholars are more likely than Democrats to end up working outside academia,as documented by Daniel Klein, an economist at George Mason University. Dr. Klein, who calls himself a classical liberal (a k a libertarian), says that the university promotes groupthink because its system of “departmental majoritarianism” empowers the dominant faction to keep hiring like-minded colleagues. And when a faculty committee is looking to hire or award tenure, political ideology seems to make a difference, according to a “collegiality survey” conducted by George Yancey.

Dr. Yancey, a professor of sociology at the University of North Texas, asked more than 400 sociologists which nonacademic factors might influence their willingness to vote for hiring a new colleague. You might expect professors to at least claim to be immune to bias in academic hiring decisions.

But as Dr. Yancey reports in his new book, “Compromising Scholarship: Religious and Political Bias in American Higher Education,” more than a quarter of the sociologists said they would be swayed favorably toward a Democrat or an A.C.L.U. member and unfavorably toward a Republican. About 40 percent said they would be less inclined to vote for hiring someone who belonged to the National Rifle Association or who was an evangelical. Similar results were obtained in a subsequent survey of professors in other social sciences and the humanities.

Dr. Yancey, who describes himself as a political independent with traditional Christian beliefs and progressive social values, advises nonliberal graduate students to be discreet during job interviews. “The information in this research,” he wrote, “indicates that revealing one’s political and religious conservatism will, on average, negatively influence about half of the search committee one is attempting to impress.”

Dr. Yancey’s research was a survey, not a field experiment, so it’s impossible to know how many of those academics who confessed to hypothetical bias would let it sway an actual decision. Perhaps they’d try to behave as impartially as the directors of graduate studies in Dr. Gross’s experiment.

The lecture is a real eye-opener. It turns out that in academia, you are likely to be viewed the same way as blacks were viewed by slave-owners, and Jews were viewed by Nazis. Stereotypes, ignorance and hatred abound.

We have a lot of work to do to correct these perceptions, and unfortunately nothing that Christians see and hear in church is likely to change this. Until we get serious about prodding our young people to think and achieve, this is what people on the secular left will think of us. Not because they really are smarter, but because we are not capable of pointing out the nonsense on their side of the aisle, e.g. – eternal universes, aliens seeding the Earth with life, fatherlessness is good for children, and so on. If we don’t study the evidence, then their stupidity will rule the day, and they are the ones who are entrenched in academia.

Scientists discover that tides affect a planet’s habitability

Circumstellar Habitable Zone

Science Daily reports on a new factor that affects planetary habitability: tides. Specifically, tides can affect the surface temperature of a planet, which has to be within a certain range in order to support liquid water – a requirement for life of any conceivable kind.

Excerpt:

Tides can render the so-called “habitable zone” around low-mass stars uninhabitable. This is the main result of a recently published study by a team of astronomers led by René Heller of the Astrophysical Institute Potsdam.

[…]Until now, the two main drivers thought to determine a planet’s temperature were the distance to the central star and the composition of the planet’s atmosphere. By studying the tides caused by low-mass stars on their potential earth-like companions, Heller and his colleagues have concluded that tidal effects modify the traditional concept of the habitable zone.

Heller deduced this from three different effects. Firstly, tides can cause the axis of a planet`s rotation to become perpendicular to its orbit in just a few million years. In comparison, Earth’s axis of rotation is inclined by 23.5 degrees — an effect which causes our seasons. Owing to this effect, there would be no seasonal variation on such Earth-like planets in the habitable zone of low-mass stars. These planets would have huge temperature differences between their poles, which would be in perpetual deep freeze, and their hot equators which in the long run would evaporate any atmosphere. This temperature difference would cause extreme winds and storms.

The second effect of these tides would be to heat up the exoplanet, similar to the tidal heating of Io, a moon of Jupiter that shows global vulcanism.

Finally, tides can cause the rotational period of the planet (the planet’s “day”) to synchronize with the orbital period (the planet’s “year”). This situation is identical to the Earth-moon setup: the moon only shows Earth one face, the other side being known as “the dark side of the moon.” As a result one half of the exoplanet receives extreme radiation from the star while the other half freezes in eternal darkness.

The habitable zone around low-mass stars is therefore not very comfortable — it may even be uninhabitable.

Here is my previous post on the factors needed for a habitable planet. Now we just have one more. I actually find this article sort of odd, because my understanding of stars was that only high-mass stars could support life at all. This is because if the mass of the planet was too low, the habitable zone wouldbe very close to the star. Being too close to the star causes tidal locking, which means that the planet doesn’t spin on its axis at all, and the same side faces the star. This is a life killer.

This astrophysicist who teaches at the University of Wisconsin explains it better than me.

Excerpt:

Higher-mass stars tend to be larger and luminous than their lower-mass counterparts. Therefore, their habitable zones are situated further out. In addition, however, their HZs are much broader. As an illustration,

  • a 0.2 solar-mass star’s HZ extends from 0.1 to 0.2 AU
  • a 1.0 solar-mass star’s HZ extends from 1 to 2 AU
  • a 40 solar-mass star’s HZ extends from 350 to 600 AU

On these grounds, it would seem that high-mass starts are the best candidates for finding planets within a habitable zone. However, these stars emit most of their radiation in the far ultraviolet (FUV), which can be highly damaging to life, and also contributes to photodissociation and the loss of water. Furthermore, the lifetimes of these stars is so short (around 10 million years) that there is not enough time for life to begin.

Very low mass stars have the longest lifetimes of all, but their HZs are very close in and very narrow. Therefore, the chances of a planet being formed within the HZ are small. Additionally, even if a planet did form within the HZ, it would become tidally locked, so that the same hemisphere always faced the star. Even though liquid water might exist on such a planet, the climactic conditions would probably be too severe to permit life.

In between the high- and low-mass stars lie those like our own Sun, which make up about 15% percent of the stars in the galaxy. These have reasonably-broad HZs, do not suffer from FUV irradiation, and have lifetimes of the order of 10 billion years. Therefore, they are the best candidates for harbouring planets where life might be able to begin.

This guy is just someone I found through a web search. He has a support-the-unions-sticker on his web page, so he’s a liberal crackpot. But he makes my point, anyway, so that’s good enough for me.

Maybe the new discovery is talking about this now, but I already knew about the tides and habitability, because I watched The Privileged Planet DVD. Actually that whole video is online, and the clip that talks about the habitable zone and water is linked in this blog post I wrote before.

Study confirms that predictions about junk DNA by materialists are false

8 Comments

First, let’s see what Darwinian evolutionists predict about junk DNA, before we look at what the experiments show.

Here’s biologist John Timmer to explain the orthodox Darwinian view of DNA from 2007:

Personally, I fall into the “it’s all junk” end of the spectrum. If almost all of these sequences are not conserved by evolution, and we haven’t found a function for any of them yet, it’s hard to see how the “none of it’s junk” view can be maintained. There’s also an absence of support for the intervening view, again because of a lack of evidence for actual utility. The genomes of closely related species have revealed very few genes added from non-coding DNA, and all of the structural RNA we’ve found has very specific sequence requirements. The all-junk view, in contrast, is consistent with current data.

Got that? According to Darwinists, DNA is almost entirely junk – this is what is consistent with the view that creatures have evolved through a process of random mutation and selection. The estimates that I’ve seen from evolutionary biologists range from 95% to 99% junk. Now let’s compare the religion with science, and separate mythology from reality.

Now let’s compare that with intelligent design theorist William Dembski’s view of “junk” DNA, from 1998:

Even if we have a reliable criterion for detecting design, and even if that criterion tells us that biological systems are designed, it seems that determining a biological system to be designed is akin to shrugging our shoulders and saying God did it. The fear is that admitting design as an explanation will stifle scientific inquiry, that scientists will stop investigating difficult problems because they have a sufficient explanation already.

But design is not a science stopper. Indeed, design can foster inquiry where traditional evolutionary approaches obstruct it. Consider the term “junk DNA.” Implicit in this term is the view that because the genome of an organism has been cobbled together through a long, undirected evolutionary process, the genome is a patchwork of which only limited portions are essential to the organism. Thus on an evolutionary view we expect a lot of useless DNA. If, on the other hand, organisms are designed, we expect DNA, as much as possible, to exhibit function. And indeed, the most recent findings suggest that designating DNA as “junk” merely cloaks our current lack of knowledge about function… Design encourages scientists to look for function where evolution discourages it.

Now let’s look at the experimental evidence and see whose prediction was proven right by the progress of science.

Science Daily reports on a recent study that confirms the previous study that falsified Darwinian predictions about junk DNA.

Excerpt:

Researchers from the Gene and Stem Cell Therapy Program at Sydney’s Centenary Institute have confirmed that, far from being “junk,” the 97 per cent of human DNA that does not encode instructions for making proteins can play a significant role in controlling cell development.

[…]Using the latest gene sequencing techniques and sophisticated computer analysis, a research group led by Professor John Rasko AO and including Centenary’s Head of Bioinformatics, Dr William Ritchie, has shown how particular white blood cells use non-coding DNA to regulate the activity of a group of genes that determines their shape and function. The work is published today in the scientific journalCell.

“This discovery, involving what was previously referred to as “junk,” opens up a new level of gene expression control that could also play a role in the development of many other tissue types,” Rasko says. “Our observations were quite surprising and they open entirely new avenues for potential treatments in diverse diseases including cancers and leukemias.”

Now, this is yet another falsification of Darwinism, to go with the other papers that I keep posting about new research that falsifies Darwinism. How many papers do we need to falsify Darwinism? I think if you are in an argument over Darwinism, and you produce these articles, then you win, so long as the other person cannot produce anything. It’s also a good idea to couple these pieces of evidence with a positive case for intelligent causes operating during the origin of life and the Cambrian explosion.
