Turkish Government Will Remove Evolution

Turkish Government Will Remove Evolution
Turkish education minister Ismet Yilmaz has announced changes to the textbooks in that country. Starting next fall, the Turkish government will remove evolution and all references to Charles Darwin from the textbooks along with 170 other topics that do not coincide with the Islamic government views. The new curriculum to replace these topics is said to be “value-based” and in harmony with student development.

The current biology course for twelveth grade biology has a section titled “The Beginning of Life and Evolution.” It is being replaced with a unit titled “Living Beings and the Environment.” This new course will include discussions of adaptation, mutation, and natural and artificial selection without mentioning evolution or Darwin. An earlier section for an eleventh-grade philosophy class will be titled “Evolution and other Ontological Opinions.”

The situation is complicated in Turkey not only because of the influence of Islam but also because of the failed coup in 2016. The government is using the schools as a way to control the population. Included in the new curriculum are units about the groups that the government is fighting such as the Kurdistan Worker’s Party and the U.S.-based Muslim cleric Fethullah Gulen.

American creationist groups that want to include their particular view of biology in education may want to look at what is happening in Turkey. The new curriculum, which is religiously based, is turning the classroom into a political football. It will be interesting to see if the Turkish government will remove evolution from the educational system without causing major civil unrest.

We have pointed out that modern agriculture, animal husbandry, aquaculture, and fish management depend upon the basic concepts that Darwin presented. The fact that animals can change and that this change can be used to benefit the world is important for young people to learn. The enemy is naturalism in which these concepts are expanded to exclude God’s role.

Titan Studies Verify Earth’s Uniqueness

Titan Studies Verify Earth's Uniqueness
Yesterday we wrote about the end of the Cassini mission. We mentioned that an early highlight of that mission was landing the Huygens probe on Titan in January of 2005. Titan is a moon of Saturn and the largest moon in our solar system. Scientists were very interested in studying Titan thinking they might find evidence of life. Instead, the Titan studies verify Earth’s uniqueness.

It took seven years for the Huygens lander to make the 2.2-billion-mile (3.5 billion km) journey to Saturn on board the Cassini spacecraft. Cassini arrived at Saturn in June 2004, but it was not until Christmas Day that the Titan probe separated from the Cassini spaceship. On January 14, the probe entered the upper atmosphere of Titan at 12,400 miles (almost 20,000 km) per hour. After opening three parachutes, Huygens eventually completed a 150-minute descent to land on the surface of Titan.

As Huygens descended to the surface, it made measurements of all kinds and turned on a spotlight to photograph its soft landing. It then sent pictures and data from the surface of Titan to the Cassini spacecraft for about an hour-and-a-half. The Cassini spacecraft relayed the data and pictures to Earth. This expedition was an incredible success and told us much about conditions in another area of the solar system.

Some experts predicted that they would find life, or at least the precursors of life, on Titan. Spectrographic analysis of the atmosphere had shown a huge amount of nitrogen and some methane (natural gas) in the atmosphere. The presence of methane was of special interest to scientists because methane, with a carbon atom and four hydrogen atoms, is the building block of more complicated organic molecules. Some biochemists predicted massive numbers of complex organic molecules in oceans of hydrocarbons on Titan–perhaps even some basic life-forms.

As the Huygens probe sent back pictures from Titan, scientists were amazed to see carved river channels, old shorelines, and clouds. With a temperature of minus 300 degrees Fahrenheit (-184 C) these obviously could not be water-carved channels. As Huygens landed, it broke through a crusty surface and sank several inches into the ground. The chemical studies of the spongy surface showed that it was not rock, but frozen gaseous material. Titan’s atmosphere could not sustain life. The clouds turned out to be methane, and scientists could find no oxygen or oxygen compounds on Titan. Titan has a spongy surface saturated with organic compounds. The density of Titan tells us that deep down under all of this organic ice there must be very dense rock.

It is becoming apparent that the other planets in our solar system have very little in common with Earth. Titan studies verify Earth’s uniqueness once again. Jonathon Lunine, a planetary scientist who worked on this project, described the findings in this way, “This is a planetary scene like no other, vaguely disturbing and nightmarish to me and certainly not Mars or Venus.”

Our point is that all the discoveries science has made about the solar system have shown how special and unique the Earth is. It is wonderful that humans can build a machine to probe such strange and exotic places. As we learn more about the universe, we see the truthfulness of the Psalmist’s words, “The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they reveal knowledge” (Psalms 19:1-2, NIV).

Cassini Exceeded Expectations

Saturn with its rings and some of its moons.Cassini Exceeded Expectations

On the morning of September 15, 2017, Cassini ended its life in fiery destruction. Cassini was a space probe orbiting and studying Saturn, and by all measures, Cassini exceeded expectations.

NASA, the European Space Agency, and the Italian Space Agency worked together on the Cassini-Huygens space exploration project. The mission was to study Saturn along with its moons and rings. NASA launched the spacecraft in 1997, and it arrived near Saturn and went into orbit around that planet in 2004.

The Huygens (pronounced hoy-guns) lander module, provided by the ESA, separated from the Cassini probe and landed on Saturn’s largest moon, Titan, in 2005. The parachute landing was successful, and the probe sent out data for about 90 minutes. In that brief time, scientists learned much about the surface of that distant moon. Viewed from Titan’s surface, the Sun appeared about the size and brightness of a car headlight 150 meters away. The Huygens probe took pictures and told us that Titan’s surface is dotted with rivers, lakes, and oceans made of methane and ethane. It also has dunes up to 300 feet (91 meters) tall.

Meanwhile, the Cassini probe continued to orbit Saturn and send back amazing and beautiful pictures of its rings and moons for 13 years. Cassini helped us to learn more about the moons of Saturn. The planet has at least 53 moons and possibly eight more. We learned that the moon Enceladus is covered with a liquid water ocean with a surface layer of ice 19 to 25 miles (30 to 40 km) thick. Geysers of water erupt from cracks in the ice. The rings of Saturn are a constantly changing collection of ice particles and small rocks. Saturn has hurricane-like storms at both poles and a hexagon-shaped jet stream at the north pole. How long is a day on Saturn? That’s hard to determine because it is a gas planet and not all parts of it move at the same speed. Scientists estimate a little more than 10 hours.

Cassini exceeded expectations by surviving seven years of travel to Saturn plus 13 years orbiting the planet. As it ran out of fuel, scientists sent it hurtling into Saturn’s atmosphere to burn up so it could not contaminate any of Saturn’s moons by crashing into them.

We are fascinated by the Cassini photos and scientists will continue to study them for years. The picture we posted shows a Cassini view of Saturn and its rings with a bright spot visible below the rings. That spot is the planet where we live. As we look at the hostile environment of space and the other planets, we realize how incredible Earth is. God has given us a place with everything we need for life. You might say that compared to any other place in the universe, Earth exceeds expectations.

Autumn Equinox and Season Design

Autumn Equinox and Season Design
We have just passed the autumn equinox and what we call “the first day of fall.” It will be late December before fall officially ends at the winter solstice. On the first day of fall here in Michigan, it was unseasonably hot, and people were griping about “where is the cool fall weather we are supposed to have?” Long before the first day of winter on December 20-21, we will have snow. Is there something wrong with the seasons, or is the trouble with our understanding?

“Equinox” suggests that the length of the day is equal to the length of the night. The Sun is overhead at the equator, and from now until December 20 it will be directly overhead at progressively greater southern latitudes until it reaches just past 23 degrees south latitude. Here in the north, the Sun’s elevation above the horizon will get progressively lower, meaning that less and less of the Sun’s energy will strike the Earth’s surface so the weather will get cooler.

The problem with this simple picture is that there is a lag in the seasons. During the summer months in the Northern Hemisphere the lakes and oceans warm from the sunshine. Water has a high specific heat, so that heat is stored and is released slowly. That means we stay warm longer than expected in the fall. In the Southern Hemisphere the picture is complicated by the fact that the Earth is closer to the Sun during their summertime, so the radiation is more intense. That might be a problem except that the Southern Hemisphere has more water than the Northern Hemisphere because oceans cover more of the southern Earth’s surface. With that greater storage and absorption capacity moderates the temperatures in the Southern Hemisphere.

The autumn equinox reminds us of the incredibly well-designed system of the Earth. It is easy to over-simplify the seasons and the equinoxes and solstices, but the system functions remarkably well. Without that careful design, the weather picture would be far more unstable than it is. Proverbs 8:22-31 speaks of wisdom’s involvement in all of the creation. We are just now beginning to understand how the system works and how our use of Earth’s resources affect the system.

Great American Eclipse “Engineered”

The Great American Eclipse
One month ago today a total solar eclipse crossed the United States. The so-called Great American Eclipse had many interesting things associated with it.

We have pointed out in previous discussions that people have attached all kinds of erroneous connections to eclipses. Some people have suggested that the eclipse predicts the doom of kings and in recent weeks the demise of Donald Trump. We have seen religious prognostications of all kinds attached to the eclipse including the second coming of Christ. There are those who have denigrated biblical events such as the darkness at the time Christ died, saying it was just an eclipse. (No eclipse can last for three hours.) None of these claims and predictions have any value.

One message that should stand out from the eclipse is the precision that God has built into the creation of the cosmos. How can astronomers predict when eclipses will occur including the exact time for a given location? This is quite simple if you understand the design of the creation. Astronomers have a grid in the sky that is an extension of the latitude/longitude system on the surface of the Earth. All objects in space, including the Sun and the Moon, can be plotted on this grid system. This allows scientists to plot the movement of the Moon and the shadow the Moon casts on Earth. (Remember that a solar eclipse is the Moon’s shadow on the Earth.)

Many of us earth science teachers use the Earth Science Curriculum Project. It has a lab where students plot an eclipse and predict what kind of eclipse will occur. They can predict when it will start, how much of the Sun will be covered, and when it will end. One of my students commenting after doing the lab, “Wow, what engineer thought up this system?” Another student responded “No engineer did it. God did it!” The first student responded, “Well God is a pretty cool engineer!”

We have pointed out that one of the problems people have with faith is that they attempt to explain everything as mysticism and magic. When it becomes obvious that planning and design are part of the system, that understanding erodes their faith in God. A good magician can mystify us, but still, he is using methods we can understand if we learn how he did it.

The Great American Eclipse spoke well about how precisely and carefully God has designed the planetary system in which we live. The eclipse is one more witness to the statement that, “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalms 19:1).

It’s Good to be Blue

It's Good to Be Blue Begonia Leaf
It’s a plant that uses quantum mechanics to make maximum use of minimum light, and in doing so, it displays blue leaves. The explanation of why blue begonias are blue is another demonstration of the incredible design built into all living things.

The tropical begonia (Begonia pavonina) that grows in Malaysia has leaves that are iridescent blue. The blue does not come from pigmentation, but rather from structural color, a technique that gives beautiful color to some birds, Butterflies, and beetles. In the leaves of all kinds of plants there are cellular capsules called chloroplasts, and inside those structures is a green substance known as chlorophyll. The chloroplasts are the organic machines that take energy from sunlight and chemicals from the soil to make organic energy that allows the plant grow.

Sunlight is a mixture of light at various energy levels, but green is the highest energy of sunlight reaching the surface of the Earth. Since the chlorophyll pigment reflects green light, the plant is protected from being damaged by the high-energy sunlight. We see the reflected green light, so the leaves look green.

Blue begonias live on the floor of dense rain forests where the forest canopy restricts the light. Inside the chloroplasts of these begonias, there are nano-structures called thylakoids where the energy conversion takes place. Other plants have thylakoids, but they are arranged differently in the begonia. Scientists using an electron microscope discovered that the thylakoids are aligned in a way that they act like crystals. In other plants, they are haphazard in their arrangement. Light bounces around within the thylakoids causing interference at certain wavelengths and reflecting the iridescent blue. The light is slowed down in this process so the plant can use more of the high-energy green and red light while reflecting the blue. These plants are using principles of quantum mechanics which scientists only began to learn about in the twentieth century.

The result is that the blue begonias get the nutrition they need to survive in a location with little sunlight, and we see the leaves as a beautiful blue. One science website described the alignment of the thylakoids in this way: “…they have an amazingly regular structure, which is obviously planned.” Here is the way another science website described the unique way these begonias efficiently use the limited sunshine they receive: “It seems selective evolution led the plants to engineer a nanoscale light-trapping structure, the likes we’ve only seen in miniature lasers and other photonic structures made by humans…”

We believe that planning requires a planner and engineering requires an engineer. As scientists study even the simplest forms of life, they find more and more evidence that God is ingenious in all He creates.

Saharan Silver Ants

Saharan Silver Ants
The survival of living things in extreme conditions is always fascinating. There are places on Earth, such as the Sahara Desert, where the temperature on the ground can soar to 120 degrees Fahrenheit. Even in that extreme heat there are living things functioning very well in conditions that would be lethal to most forms of life.

Extreme survival is a way of life for the Saharan silver ants (Cataglyphis bombycina). The predators of these ants are desert lizards that retreat into their burrows in the heat of the day. Some of the ants keep watch to let the others know when the lizards are gone. Then the ant colony makes its food-search expedition. They come out into the full Sun and intense heat to scavenge animal carcasses. The picture shows them devouring an engorged camel tick.

The question is, “How do they survive the heat?” They have longer legs than most ants, and that keeps their bodies farther from the hot sand. They also travel across the sand at high speed (2.3 feet or 0.7 meters per second) using only four of their six legs to keep fewer feet on the ground. Also, their bodies produce heat-shock proteins that help their cells cope with the stress of the high temperature. Many animals produce heat-shock proteins, but not until they are exposed to extreme heat. The Saharan silver ants are programmed to produce those proteins before heat exposure to prepare them for what’s ahead.

Even with those adaptations, they are still exposed to the direct rays of the Sun. Scientists used electron microscopes to find the secret of the Saharan silver ant’s survival. The ants are covered with microscopic hairs that are not round or oval in cross-section like most hairs. They have a triangle shape to act as prisms. This shape reflects both the visible and infrared (heat) energy from the Sun away from their bodies. Because of these tiny prisms, the ants display a metallic shine. They look like metallic beads rolling quickly over the desert sand. No other desert creature has this form of reflection. Saharan silver ants are among the most heat-resistant creatures in the world.

Like many things in nature, engineers are looking into how we can imitate the prism method of these ants to protect humans from the dangers of extreme heat. Designing something that can reflect the heat this efficiently requires a deep understanding of optics and the nature of light and heat energy. The wisdom of the Creator shines brightly in the reflected light coming from the Saharan silver ants.

Can God Create a Rock He Can’t Move?

Can God create a rock He can't move?
Can God create a rock He can’t move? That is a recurring question we see just about every day in someone’s email. The idea is that if God can do anything, He should be able to create a rock so big He can’t move it. But that would mean there is something He cannot do. Many times the question is sent along with a quote of Matthew 19:26 where Jesus said, “With men this is impossible, but with God all things are possible.” There are multiple errors in both the question and in the questioners’ concept of God.

I want to make it clear that there are things that God cannot do. The Bible says, “It is impossible for God to lie” (Hebrews 6:18). There are many things associated with evil that God cannot do because they would violate His very nature. That should be so obvious that no thinking person would want to debate it.

It is also important to understand that God cannot renege on His promises. The Bible is full of promises of God, beginning with Genesis 3:15. The New Testament treats those promises as iron clad–something that God cannot break. Take a few minutes to look at Acts 13:23, Romans 4:21, Galatians 4:4, Hebrews 10:23, and Hebrews 11:11. It is important to Christians that the promises of God apply to us today, and that promises concerning eternity can be trusted. (See Matthew 10:32, Matthew 25:46, and 2 Timothy 2:12.)

God cannot hear the prayers of sinful people who reject God and His teachings. The Old Testament tells us that in Isaiah 59:1-2, Proverbs 1:24,28 and 28:9. In the New Testament, we all know the promise in John 3:16 that “whoever believes in (Jesus)…will have everlasting life.” We also see in Mark 16:15-16 that the lack of belief leads to condemnation. John 8:24 and Romans 1:16 and 10:1 carry the same message.

So when Jesus said, “with God, all things are possible?” in Matthew 19:26, what was He talking about? To understand any passage in the Bible (or any other book), you need to look at who said it, to whom, why, and how the people it was spoken to would have understood it. In this case, Jesus is talking about how hard it is for a rich person to “enter the kingdom of God.” He said it would be “easier for a camel to go through the eye of a needle.” The disciples asked how anyone could be saved. Jesus answered in verse 26, “With man this is impossible, but with God all things are possible.”

From a human standpoint, giving up riches for something religious seems impossible. But God’s love is so great and His grace so sufficient that even a rich person can be saved. The statement certainly doesn’t apply to moving a physical rock, but rather a spiritual boulder.

Someone asked Marshall Keeble, a great old black preacher, the question, “Can God create a rock He can’t move?” His response was “Yep, and He can create a bulldozer big enough to do the job.” God uses unlikely tools to accomplish impossible challenges. Using an old physics teacher to answer questions like this one is improbable, to say the least. But the fact that you read this discussion this far indicates that no matter how unlikely it might be from a human standpoint, sometimes it works.

Transactive Memory and the Bible

Transactive Memory and Couples
Many times a new concept appears in the scientific literature, and when we look at it, we see that it is something that the Bible has already described. A recent example of this is a concept given by social psychologist Daniel Wegner called transactive memory.

Transactive memory is defined as “a shared system for encoding, storing, and retrieving information.” Wegner explains this concept in this way: “People in close relationships know many things about each other’s memories. One partner may not know where to find candles around the house, for instance, but may still be able to find them in a blackout by asking the other partner where the candles are. Each partner can enjoy the benefits of the pair’s memory by assuming responsibility for remembering just those items that fall clearly to him or to her and then by attending to the categories of knowledge encoded by the partner so that items within those categories can be retrieved from the partner when they are needed. Such knowledge of one another’s memory areas takes time and practice to develop, but the result is that close couples have an implicit structure to carrying out the pair’s memory tasks.”

Psychologists are using this concept to help people dealing with the death of a spouse. As a person who has gone through that experience, I can testify that when your wife of 49 years dies, a part of you seems to die too. Panic attacks after the death of a spouse are common, and that is when you suddenly are faced with having lost a large part of your memory.

Bible readers will recognize this “new” concept. In the Old Testament, a variety of transactive memory devices were commanded and put in place by God. Deuteronomy 6:4-9, 12, 20; Exodus 13:14; and Joshua 4:6 are all cases where devices such as writing history on door posts were given to help remember the past and teach children the value of a culture. The various feasts of Israel in Exodus 23:15-16 were transactive memory devices.

In the New Testament, the congregation was developed as a transactive device. Acts 2:41-47 shows transactive memory helping the first century Church. James 5:14-16 described congregational conduct in various circumstances in life. The Bible itself is a transactive device as it is described in 2 Timothy 3:14-17.

One of the problems with megachurches is that much of the transactive memory value of the local congregation is lost. It is hard to pray for or to encourage someone you don’t know. Death is of little meaning if you don’t know the person. The congregational conduct discussed in Hebrews 10:22 is difficult in a huge congregation.

When Jesus prayed for unity, He gave us something that can sustain us in every stage of life and in every crisis. We defeat that blessing when we make entertainment the focus of our worship and when we don’t build relationships that allow transactive memory to function. Transactive memory may be new to the world of social psychology, but it is as old as the Bible itself.

Homeopathic Nonsense

Homeopathic Nonsense
There are many negative spin offs of the “evolution creation controversy” and the view that science and religion are opponents. One of the most destructive is the skepticism of natural medical remedies by opponents of religion, and the blind acceptance of them by believers.

Science and faith are friends, and science by definition is knowledge (see Webster’s Dictionary) and involves an organized way to arrive at facts. There are natural things that scientific research has shown to be useful in treating ailments and pain. Aspirin is a natural material that has many medical benefits, and some plants such as aloe help relieve sunburn. The list of tested natural materials that help us medically is very long.

Jesus pointed out that natural things can serve us in profitable ways. In Matthew 16:2-3 he told about the use of natural things to predict the weather. In 1 Timothy 5:23 Paul pointed out a use of the wine of that day for stomach problems. However, homeopathic nonsense originated in 1796 based on a false theory that “like cures like.” In other words, if you take something that causes an illness and dilute it with water or alcohol until there is nothing left of it, that dilute solution will cure the ailment.

One homeopathic “cure” is Boiron’s Oscillococcinum. The manufacturer claims that it cures cold and flu symptoms. Some drug stores sell it on the shelf with Tylenol. It has been marketed for years based on the false claim that Oscillococcinum is a bacteria that causes influenza. There is no bacteria by that name and colds and flu are caused by viruses and not by bacteria. The inventor claimed that he found the bacteria in patients with Spanish flu in 1917 and also in the liver of the Muscovy duck. The duck liver is diluted to one part duck liver with 10 to the 400th power parts of water. (That would be one followed by 400 zeroes, or virtually pure water.) Other ingredients (sucrose and lactose) are added to make it into pills. In other words, it is a sugar pill placebo.

Just because a product is “natural” doesn’t mean it gives any health benefits. Although many natural products do contribute to our health, many other natural products are toxic to the human body. God expects us to use evidence and common sense in applying what He has given us to treat our ailments, and we can start by avoiding homeopathic nonsense.
