Dr. Walter L. Bradley (C.V. here) is the Distinguished Professor of Engineering at Baylor.

Here’s a bio:

Walter Bradley (B.S., Ph.D. University of Texas at Austin) is Distinguished Professor of Engineering at Baylor. He comes to Baylor from Texas A&M University where he helped develop a nationally recognized program in polymeric composite materials. At Texas A&M, he served as director of the Polymer Technology Center for 10 years and as Department Head of Mechanical Engineering, a department of 67 professors that was ranked as high as 12th nationally during his tenure. Bradley has authored over 150 refereed research publications including book chapters, articles in archival journals such as the Journal of Material Science, Journal of Reinforced Plastics and Composites, Mechanics of Time-Dependent Materials, Journal of Composites Technology and Research, Composite Science and Technology, Journal of Metals, Polymer Engineering and Science, and Journal of Materials Science, and refereed conference proceedings.

Dr. Bradley has secured over $5.0 million in research funding from NSF grants (15 yrs.), AFOSR (10 years), NASA grants (10 years), and DOE (3 years). He has also received research grants or contracts from many Fortune 500 companies, including Alcoa, Dow Chemical, DuPont, 3M, Shell, Exxon, Boeing, and Phillips.

He co-authored The Mystery of Life Origin: Reassessing Current Theories and has written 10 book chapters dealing with various faith science issues, a topic on which he speaks widely.

He has received 5 research awards at Texas A&M University and 1 national research award. He has also received two teaching awards. He is an Elected Fellow of the American Society for Materials and the American Scientific Affiliation (ASA), the largest organization of Christians in Science and Technology in the world. He is President elect of the ASA and will serve his term in 2008.

You can read more about his recent research in this article from Science Daily.

Below, I analyze a lecture entitled “Is There Scientific Evidence for an Intelligent Designer?”. Dr. Bradley explains how the progress of science has made the idea of a Creator and Designer of the universe more acceptable than ever before.

The MP3 file is here.

Evidence #1: The design of the universe

1. The correspondence of natural phenomena to mathematical law

  • All observations of physical phenomena in the universe, such as throwing a ball up in the air, are described by a few simple, elegant mathematical equations.

2. The fine-tuning of physical constants and rations between constants in order to provide a life-permitting universe

  • Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
  • In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
  • Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
  • The range of possible ranges over 70 orders of magnitude.
  • Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).

Examples of finely-tuned constants and ratios: (there are more examples in the lecture)

a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)

  • if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
  • if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
  • So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)

b) The conversion of beryllium to carbon, and carbon to oxygen

  • Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
  • Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
  • The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
  • If you mess with these forces even slightly, you either lose the carbon or the oxygen.

3. Fine-tuning to allow a habitable planet

  • A number of factors must be fine-tuned in order to have a planet that supports life
  • Initial estimates predicted abundant life in the universe, but revised estimates now predict that life is almost certainly unique in the galaxy, and probably unique in the universe.
  • Even though there are lots of stars in the universe, the odds are against any of them supporting complex life.
  • Here are just a few of the minimal requirements for habitability: must be a single star solar system, in order to support stable planetary orbits, the planet must be the right distance from the sun in order to have liquid water at the surface, the planet must sufficient mass in order to retain an atmosphere, etc.

The best non-theistic response to this argument is to postulate a multiverse, but that is very speculative and there is no experimental evidence that supports it.

Evidence #2: The origin of the universe

1. The progress of science has shown that the entire physical universe came into being out of nothing (= “the big bang”). It also shows that the cause of this creation event is non-physical and non-temporal. The cause is supernatural.

  • Atheism prefers an eternal universe, to get around the problem of a Creator having to create the universe.
  • Discovery #1: Observations of galaxies moving away from one another confirms that the universe expanded from a single point.
  • Discovery #2: Measurements of the cosmic background radiation confirms that the universe exploding into being.
  • Discovery #3: Predictions of elemental abundances prove that the universe is not eternal.
  • Discovery #4:The atheism-friendly steady-state model and oscillating model were both falsified by the evidence.
  • And there were other discoveries as well, mentioned in the lecture.

The best non-theistic response to this argument is to postulate a hyper-universe outside of ours, but that is very speculative and there is no experimental evidence that supports it.

Evidence #3: The origin of life

1. The progress of science has shown that the simplest living organism contains huge amounts of biological information, similar to the Java code I write all day at work. This is a problem for atheists, because the sequence of instructions in a living system has to come together all at once, it cannot have evolved by mutation and selection – because there was no replication in place prior to the formation of that first living system!

  • Living systems must support certain minimum life functions: processing energy, storing information, and replicating.
  • There needs to be a certain amount of complexity in the living system that can perform these minimum functions.
  • But on atheism, the living system needs to be simple enough to form by accident in a pre-biotic soup, and in a reasonable amount of time.
  • The minimal functionality in a living system is a achieved by DNA, RNA and enzymes. DNA and RNA are composed of sequences of proteins, which are in turn composed of sequences of amino acids.

Consider the problems of building a chain of 100 amino acids

  • The amino acids must be left-handed only, but left and right kinds are equally abundant in nature. How do you sort out the right-handed ones?
  • The amino acids must be bound together using peptide bonds. How do you prevent other types of bonds?
  • Each link of the amino acid chain needs to be carefully chosen such that the completed chain with fold up into a protein. How do you choose the correct amino acid for each link from the pool of 20 different kinds found in living systems?
  • In every case, a human or other intelligence could solve these problems by doing what intelligent agents do best: making choices.
  • But who is there to make the choices on atheism?

The best current non-theistic response to this is to speculate that aliens may have seeded the Earth with life at some point in the past.

The problem of the origin of life is not a problem of chemistry, it is a problem of engineering. Every part of car functionality can be understood and described using the laws of physics and chemistry. But an intelligence is still needed in order to assemble the components into a system that has the minimal requirements for a functioning vehicle.

Seven videos from the Biola University conference on God and evolution

1 Comment

I have been weaseling out of my apologetics posting this week, and this is my last chance to get something good up so I can make it onto Brian Auten’s weekly apologetics bonus links at Apologetics 315, the best Christian apologetics site ever.

So I am posting SEVEN video clips from a recent Biola University conference on theistic evolution. (H/T Mysterious Jonathan)

Conference details:

Can you believe in God and Darwinian evolution at the same time? Scientists and scholars have an answer that may surprise the audience as they explore this and related questions at the God & Evolution conference on Saturday, October 16, 2010 at Biola University in La Mirada, California.

The conference will focus on the conflict between neo-Darwinism and traditional theological views of Protestants, Catholics and Jews.

What is “theistic” evolution, and how consistent is it with traditional theism?

What challenges does Darwin’s theory pose for Protestants, Catholics, and Jews?

Is it “anti-science” to question Darwinian Theory?

These questions and more will be addressed at the one-day conference by Marvin Olasky, editor of World magazine, biologist Jonathan Wells, political scientist John West, philosopher Jay Richards, attorney and science writer Casey Luskin and authors David Klinghoffer and Denyse O’Leary.

In the century and a half since Charles Darwin first proposed his theory of evolution, Christians, Jews, and other religious believers have grappled with how to make sense of it. Most have understood that Darwin’s theory has profound theological implications, but responses have varied dramatically.

Some believers have rejected it outright; others, including “theistic evolutionists” such as Francis Collins and Karl Giberson, have sought to reconcile Darwin’s theory with their religious beliefs, often at the cost of clarity, orthodoxy, or both. As a result, the whole subject of God and evolution is a source of confusion for many believers.

Join us for this one-day seminar, featuring contributors to the new book, God and Evolution, exploring these issues and offering a wide-ranging critique of those who seek to reconcile materialistic theories such as Darwinism with belief in God.

Here is the playlist for all SEVEN video clips.

Clip 1 of 7: Jay W. Richards: The Central Issues (34 minutes)

Clip 2 of 7: John G. West: Three Big Questions (22 minutes)

Clip 3 of 7: Casey Luskin: Why the New Atheists Won’t Be Appeased (21 minutes)

Clip 4 of 7: Denyse O’Leary: Catholics & Evolution (29 minutes)

Clip 5 of 7: David Klinghoffer: Judaism & Evolution (17 minutes)

Clip 6 of 7: Jonathan Wells: Science and Theistic Evolution (26 minutes)

Clip 7 of 7: Panel Discussion with Marvin Olasky (99 minutes)

So it looks like there are 2 Catholics (Richards, O’Leary), 2 Jews (Luskin, Klinghoffer), 2 Protestants (West, Olasky) and 1 “Other” (Wells) in that list. It’s a diverse group.

ID critics do not read ID books before reviewing them

7 Comments

From Evolution News.

Excerpt:

As a friend of ours puts it, Jonathan Wells’s The Myth of Junk DNA is in the process of being “Ayala’ed.” To “Ayala” a book is to attack it in review without having bothered to read or even read much about it, simply on the basis of what you think it probably says given your uninformed preconceptions about the author. The term comes from the wonderful instance where distinguished biologist Francisco Ayala pompously “reviewed” Stephen Meyer’s Signature in the Cell for the Biologos Foundation website while giving clear evidence of not having cracked the book open or even looked at the table of contents.

Thus we have several posts from University of Toronto biochemist Larry Moran, criticizing Myth while being totally open about not having read it first. Moran wrote no fewer than four posts on the book in this fashion, claiming as an excuse that Myth would not be published in Canada until May 31. (In fact, the book was available for purchase from Amazon since early May.) And now, as Casey already noted, we have Forbes science writer John Farrell, citing Moran as his source — a “double Ayala,” so to speak, where you attack a book without reading it citing as justification a review by someone else who also hasn’t read it.

Farrell thinks the myth of junk DNA is itself a myth — that “scientists never dismissed junk DNA in the literature.” In other words, Wells has set up a straw man. Of course, not having looked at the book, Farrell can’t have consulted Dr. Wells’s fifty pages of notes documenting his argument. The notes may be downloaded for free here. (Also available in Canada.)

So this is what criticism of intelligent design amounts to… denouncing a book before reading it.

Biophysicist Cornelius Hunter explains why reading the book is not necessary for Darwinists – because Darwinism is impervious to evidential concerns.

Excerpt:

This centuries old framework for naturalism is key to understanding evolution today. Science writers such as Farrell report that scientists have discovered, for instance, “just how not-so-intelligently designed the human genome actually is,” but this is not a scientific conclusion. For unlike the target of his criticism (the ID theory) which refers to complexity rather than goodness of design, evolutionary thought and its underlying naturalism framework refer to the design’s metaphysics. As Farrell explains:

Many mutations are neutral, or can be easily overcome by technology. And some of them cause a great deal of psychological suffering, such as the mutation that causes trimethylaminuria, which is physically harmless but causes the victims to smell like rotten fish no matter how clean they are. But many other mutations are deadly or, worse yet, can cause a person to have a lifetime of suffering. Perhaps the most disturbing mutation is the one that causes Lesch-Nyhan syndrome. This one mutation, of a single amino acid in a protein, causes the victim to have an uncontrollable compulsion for self-mutilation: they chew their own lips and fingers, and find sharp objects to stab their faces and eyes. The victims are fully able to feel their pain and they know what they are doing, but cannot control it.

Obviously to argue such mutations are the product of intentional design is to suggest the deity or intelligence responsible, is something of a monster.

Indeed. Leibniz was concerned about the evil in the world, but he had no idea how deeply it runs. It is truly abominable, and it makes for a moving and powerful argument that no good creator who has the power to create a universe would ever create this one.

Whether by the Epicurean’s swerving atoms, or science’s natural laws, the world must have arisen on its own.

How could anyone deny this obvious conclusion? This and other metaphysical arguments leave no room for debate. Evolution must be true. We may not know how it occurred, but it is a fact.

The powerful theory of evolution hangs on this framework of thought that mandates naturalism. The science is weak but the metaphysics are strong. This is the key to understanding evolutionary thought. The weak arguments are scientific and the strong arguments, though filled with empirical observation and scientific jargon, are metaphysical. The stronger the argument, the more theological or philosophical.

(Emphasis is in the original)

And I recommend you read the whole post, especially if you’ve never read anything by Cornelius Hunter.

So the reason why Darwinists don’t care about evidence is because evidence is irrelevant once you pre-suppose the religion of naturalism. And you presuppose the religion of naturalism because of the problem of evil and suffering. I.e. – “based on my childhood caricature of God as the cosmic Santa Claus, I now see that evolution must be true, because my cosmic Santa Claus God cannot have any purpose for allowing the evil and suffering I see in nature.” Science has nothing to do with it. Nature is not nice, and so God didn’t make nature. And that’s the end of the discussion.

These Darwinian critics of ID are really just close-minded religious fundamentalists whose principal response to experimental science is uninformed religious bluster. You don’t get an education when you take classes from the Darwinbots – you get indoctrinated. And if you dissent you get failed or fired. It’s that simple. They don’t debate you – they censor you. They don’t produce evidence for their views, they insult you. How dare you call their religion into question by appealing to facts? Darwinists don’t like facts. They don’t like evidence.
