I love going to homeschool conventions. This past weekend, I spoke at the Texas Homeschool Convention, and it was a wonderful experience. I got to talk with a lot of interesting people, like the great granddaughter of Maria von Trapp. I also got a headache from discussing quantum physics, mechanistic naturalism, and determinism with two of the philosophers I mentioned in a previous post. Of course, I also got to talk with students who have used and are using my courses. One of those students was incredibly enthusiastic, asking me several questions about science. During the course of the convention, she drew me the wonderful picture you see above, which is of a spinosaurus. He is the villain in a story she is writing.

Speaking of dinosaurs, I got a very interesting question during one of my talks. A student who was obviously interested in science asked if I had heard about the pregnant Tyrannosaurus rex that had recently been found. I was surprised by the question for two reasons. First, I had not heard about it, and I try to keep up on the latest events in science. The fact that this student knew a current event in science that I had not heard about really surprised me. Second, it seemed strange that someone would say a Tyrannosaurus rex was pregnant, since all that we know indicates it was a reptile, meaning it laid eggs. I think the term “pregnant” refers to carrying a developing fetus, so it wouldn’t be applied to an egg-laying animal.

Due to the wonders of in-flight internet, I was able to investigate the student’s question on my flight home. Sure enough, there were a lot of news stories about a pregnant Tyrannosaurus rex (see this one, for example). However, when I found and read the scientific paper upon which the stories were based, it became clear to me that the news outlets were doing their typically less-than-stellar job of reporting on science.

This Is Why You Shouldn’t Pay Attention to Most Surveys

A possible warning label for food?

A possible warning label for food?

As a nation, we seem to be addicted to surveys. We want to know what other people think about politics, education, celebrities, music, television shows, movies, science, etc. I have never understood that. While I might find a survey interesting from time to time, I honestly don’t worry much about what most people think. Perhaps that’s why it doesn’t bother me when people complain about my “contrarian” views, as one professor recently described them. While I strongly value the opinions of many people I know, I really couldn’t care less about what the majority of people (including the majority of scientists) think.

Well, I recently came across a survey that might help me understand why the opinion of the majority means little to me. It was done by the Oklahoma State University Department of Agricultural Economics. This particular survey is performed online monthly and tries to track “consumer preferences and sentiments on the safety, quality, and price of food at home and away from home with particular focus on meat demand.” Even though most of the questions on the survey are consistent from month-to-month, ad hoc questions can be added.

For the June 2016 survey, three new ad hoc questions were added. One of them asked the respondents whether they support or oppose a mandatory label on all foods containing DNA. It turns out that 80% of the respondents supported the idea! By contrast, 82% supported mandatory labels on foods produced with genetic engineering, and only 69% supported mandatory calorie labels on restaurant foods.

Now, of course, I suspect that most of my readers are educated enough to understand how silly it is to want mandatory labels on foods that contain DNA. However, just in case it escapes some people: Most of the food we eat contains DNA! When you eat a vegetable, for example, you are eating plant tissues that are made up of plant cells. Each and every cell holds the plant’s DNA in its nucleus. When you eat meat, you are eating an animal’s muscles, which are composed of muscle cells. Once again, muscle cells contain the animal’s DNA. It is very difficult to eat without ingesting the DNA of the organism you are eating!

Think about that for a moment. In this survey, 82% of people think there should be a warning label on foods that were produced with genetic engineering. However, the majority of those people also think there should be a warning about something that is in nearly every food we eat! Why in the world should we take advice about genetically-modified food from people who clearly don’t know much about the very molecule that is modified to make those foods? Also, since there were fewer people who supported mandatory calorie labels on restaurant foods, at least some of the people who are worried about DNA being in food don’t seem to be worried about how restaurant food can contribute to a real health issue: obesity!

This survey tells me two things: First, science education in the U.S. is abysmal. Of course, there are lots of other things that have already demonstrated that! Second, we shouldn’t listen to surveys when it comes to making decisions.

When Children Became People

Dr. O.M. Bakke has an odd name. No, really – his name is Odd Magne Bakke, and he is an Associate Professor of Church History at the School of Mission and Theology in Stavanger, Norway. For many reasons, including the fact that he is the father of three children, Bakke investigated the lives of children in ancient times. He focused on A.D. 100 to A.D. 450, contrasting the prevailing views of the Romans at the time to the developing views of Christians, as seen through the writings of the early church fathers. The result is When Children Became People, an eye-opening book that left me both disgusted and astounded. As I have pointed out previously (here and here), Christianity was absolutely essential in producing modern science. I had no idea idea, however, how essential it was in producing our modern view of the importance of children.

As anyone familiar with the Bible probably knows, there was a time during the ministry of Jesus when children were brought to Him so that He could bless them. The disciples rebuked the children, but Jesus said:

Let the children alone, and do not hinder them from coming to Me; for the kingdom of heaven belongs to such as these. (Matthew 19:14)

Until reading this book, I had no idea what a radical statement that was in New Testament times. As Bakke documents in his book, children were not valued in Rome. Instead, they were not really considered human beings. For example, when a child was born, the father could refuse to accept him or her into the family. Indeed, the father generally had eight to nine days to consider the matter. If the father decided the child was worthy of being a member of the family, a ritual was held, celebrating the child’s good fortune. If not, the child was simply abandoned, a practice referred to as expositio. As Bakke informs us:

…as far as the Eastern region of the Roman empire was concerned, expositio was socially accepted and widespread from the time of Alexander the Great onward. (p. 29)

Bill Nye Continues To Talk About Things of Which He is Ignorant

Bill Nye, who knows hardly anything about philosophy

Bill Nye, who knows hardly anything about philosophy

Bill Nye is a popular “scilebrity.” Unfortunately, he does an enormous disservice to science, frequently speaking on topics about which he knows very little. He narrated a faked experiment on global warming because he doesn’t understand the physical mechanisms governing how infrared light interacts with matter. If he did, he would have realized that the experiment he narrated couldn’t possibly have worked. He excludes ideas simply because he doesn’t care for them and encourages others to do the same. He wrote a book about evolution that is riddled with errors, and he tried to defend abortion using an argument that is demonstrably false.

Unfortunately, he doesn’t seem to learn from his mistakes. Instead of educating himself on an issue before discussing it, he continues to pontificate on things about which he knows nearly nothing. His latest silliness is on the subject of philosophy. While Olivia Goldhill has written an excellent discussion of why that video is so ludicrous, I want to add just a couple of thoughts.

A while back, I wrote about Dr. Kevin R. Grazier, a planetary scientist at NASA’s Jet Propulsion Laboratory and a science consultant for film and television. I briefly mentioned that he confirmed some of my thoughts regarding Bill Nye and Dr. Neil deGrasse Tyson, but Nye’s inane video leads me to expand on that point. In addition to discussing errors that Nye and Tyson have made regarding the science found in film and television, Grazier said that in his view, both Nye and Tyson aren’t really interested in educating the public about science. If they were, they would be more accurate in their pronouncements. Instead, they are just trying to convince the public that they are really smart guys.

The Inquisition Strikes Again

Karl Aspelin’s painting of Martin Luther burning the papal bull that excommunicated him from the Roman Catholic Church.

There are times when modern scientists act like members of the Inquisition. Such situations can result in people getting removed from their positions in the scientific community, courses being shut down, scientists being fired, or papers being retracted. (see here, here, here, here, and here). Unfortunately, it has happened again, resulting in another scientific paper being retracted.

The paper, Biomechanical Characteristics of Hand Coordination in Grasping Activities of Daily Living, discussed the results of an experiment that tried to figure out the functional link between the architecture of the hand and its coordination. In the experiment, 30 individuals (15 men and 15 women) with apparently healthy hands were given a glove to wear while performing several mundane tasks. The glove measured the angles of the joints in the hand throughout the time each task was being performed. This allowed the researchers to then determine the degree to which the movements of the hand joints were coordinated.

The researchers found that while some joints (particularly those of the thumb) did move independently of the others, there was an enormous amount of coordination between the joints. The authors note:

This suggests that there is no need for the human hand to control each joint independently. If there was not such biomechanical architecture, such as the separated connection of each articular from a single muscle, it would significantly increase the computational burden of the [central nervous system] to make up for the loss of the biomechanical architecture.

In other words, the joints of the hand are coordinated so that the brain doesn’t have to concentrate on controlling each joint independently when the hand is grasping objects.

Why was this scientific paper retracted? Was there a serious methodological error in the experiment? Was the data analysis incorrect? Did the authors commit some sort of fraud? No. It was retracted because the authors dared to do something that scientists have done throughout the vast majority of human history: They dared to mention the Creator in their scientific work!

Review of Evolution: Still A Theory in Crisis

Dr. Michael Denton's latest book

Dr. Michael Denton’s latest book

Back in January, I read that Dr. Michael Denton was about to release a new book on evolution. I ordered it right away and started reading it as soon as I could, because I thought that his previous book, Evolution: A Theory in Crisis, was amazing. For a long time, I considered it the best discussion of evolution that was available to the general public. However, like all books on scientific issues, much of the information became outdated over the years, so I was really excited that he was releasing a new book on the same subject.

Dr. Denton earned an M.D. from Bristol University and a Ph.D. in biochemistry from King’s College London. After earning his Ph.D., he was appointed to the faculty at La Trobe University in Australia. He then did pathology work in England, Canada, and Australia. Eventually, he ended up on the faculty at the University of Otago in New Zealand. Currently, he is a Senior Fellow at the Discovery Institute’s Center for Science and Culture, which tells you he is a member of the “intelligent design” community. His dual training in medicine and biochemistry, as well as his experience working in several different countries, gives him an interesting perspective on science in general and evolution in particular.

Like his previous book, this one is encyclopedic. It covers a wide range of topics, but unlike his previous book, it is focused on the difference between structuralism and functionalism. The way he constructs the two positions, all Darwinists fall into the functionalism camp. They believe that structures develop in nature because they are functional. After all, natural selection is constantly weeding out poor adaptations and preserving useful ones. As a result, whether or not it is functional determines whether or not it exists in the biological world. Denton, however, argues for structuralism, a view that was quite in vogue in the 18th and 19th centuries. In this view, there are certain structures that are inherent in the world, and life makes use of those predefined structures. As Denton writes:

It is hard to imagine two scientific frameworks as diametrically opposed as structuralism and functionalism. Where functionalism suggests that function is prior and determines structure, structuralism suggests that structure is prior and constrains function. (Kindle e-reader, Chapter 1: Introduction)

Honeybees Are Recovering in the U.S.

This graph shows the number of honeybee colonies in the U.S. each year. (click for source)

Have you seen the headlines? “Beekeepers Feel the Sting of Climate Change,” “Climate change crushes bee populations,” and “Bees Are Losing Their Habitat Because of Climate Change.” Yes, the world is running out of bees and “climate change” aka “global warming” is to blame. Of course, the science behind the entire concept of human-induced, catastrophic climate change is shaky at best, so it is hard to understand how anyone can take such headlines seriously. Nevertheless, there are those who think that bees are on their way to extinction, and human-induced climate change is to blame. Of course, like most of the statements made by global warming alarmists, the facts tell us something completely different.

An excellent article published in the journal Science, for example, tells us that the main reason honeybee colonies have struggled recently is because of the spread of a virus called the deformed wing virus. It is carried by a mite called Varroa destructor, which has been infesting Asian honeybee colonies since at least the 1960s. When European honeybees were introduced to Asia, the mite was able to jump to the European species, and as a result, it began spreading around the world.1

Why should we care about bees dying off? Because they are very important pollinators. In order for a flowering plant to produce fruit, pollen from one flower must travel to another flower and fertilize the egg cells found there. While wind can carry pollen, insects are much more efficient at the job. Bees are especially important when it comes to pollination. They are the main pollinators of 130 crop species in the United States and 400 crop species worldwide.2 Bees are so important that a French periodical for beekeepers reported:3

Professor Einstein, the learned scientist, once calculated that if all bees disappeared off the earth, four years later all humans would also have disappeared.

Gravitational Waves Detected!

This is an artist's conception of two merging black holes and the gravity waves they generate.

This is an artist’s conception of two merging black holes and the gravity waves they generate.

Einstein’s General Theory of Relativity makes some outlandish claims. For example, it says that the rate at which time passes depends on the strength of the gravitational field to which you are being exposed. It also says that gravity isn’t really a force. Instead, it is a consequence of how massive bodies warp spacetime, a four-dimensional mesh in which the three dimensions of space are merged with time. When I first read about this wild theory, the scientist in me was very skeptical. However, its predictions have been verified time and time again, so the scientist in me is forced to accept it as a reasonable description of the natural world.

For example, the global positioning system (GPS) must take relativity into account in order to work properly. Because they are farther from the center of the earth, the satellites that make up the GPS experience a lower force of gravity than we do on the surface of the earth. As a result, time passes more quickly for them than it does for us. If this were not taken into account, the GPS couldn’t accurately determine your absolute position on the surface of the earth.1 (There are many other factors that must be taken into account, including the effect of relative motion on time, but that is a part of Einstein’s Special Theory of Relativity and is not related to this post.)

Of course, there are many other confirmations of Einstein’s General Theory of Relativity. Mercury’s closest approach to the sun is best explained by general relativity. General relativity gives the only correct description of how a massive object bends the path of light. An experiment first done in 1959 showed that gravity causes a shift in the wavelength of light, which was predicted by general relativity. More recently, satellites confirmed a process called frame dragging, which is also a prediction of general relativity.

Just a few days ago, Physical Review Letters published a paper that provides yet another confirmation of general relativity, but this one is more important than many of the others.

What are the differences between my old chemistry course and my new chemistry course?

The cover of my new chemistry course.

The cover of my new chemistry course.

If you have been reading my blog for a while, you might know that I recently wrote a new chemistry course. The publisher of my old chemistry course came out with a new edition, and they did not consult me. This happened with another course, and the result was excellent. However, the new edition of the chemistry course was riddled with errors. Many of the errors weren’t just typos or minor mistakes in the solutions to the problems. They were serious scientific errors that would put students at a disadvantage in their future studies. I asked the publisher to make my old chemistry course available for those who wanted to avoid such errors, but it refused. As a result, I wrote a new chemistry course, Discovering Design with Chemistry.

I was recently asked on Facebook about the differences between my old chemistry course and my new one. While I have touched on that issue in a couple of other posts, I thought I would provide a thorough answer to that question here.
