Religious Anti-Science Rhetoric

For the 51 years of this ministry, we have confronted religious anti-science rhetoric. Our critics are those who feel that science is an enemy and that you can’t be a good Christian and embrace science. We are now in a period when the issue of whether people can meet together for worship services has become an issue of science and politics. Some politicians oppose churches resuming worship services saying there is strong scientific evidence that it will expose participants to the COVID-19 virus. Many religious leaders insist that this is an attempt by the government to restrict religion. They say that this scientifically-based objection is destroying the right of people to worship together.

In previous articles, we have pointed out that a great deal of ignorance is involved in rejecting science. According to the dictionary, science is knowledge. Knowledge is always neutral. The critical thing is how we use it. When new scientific knowledge gave us lasers, the question was how we would use lasers. Would they be weapons that cause massive destruction, or would they be medical tools to heal eyes?

We now understand how the COVID-19 virus spreads from one person to another. Will we use this knowledge to stop the progression of the illness, or will we use this virus to destroy whole masses of people? The bubonic plague from 1347-1351 killed 200 million people, which was nearly half of Europe’s population. Religious anti-science rhetoric today has the potential to create a catastrophe.

It isn’t our knowledge about the COVID-19 virus that is a threat to freedom or to worship. The reality is that science will eventually develop a vaccine that will allow everyone to worship together. Smallpox was killing 400,000 people a year in Europe, and it only stopped when scientists developed a vaccine. It is hypocritical for religious people to vilify science while they: 1) enjoy modern technology in their entertainment 2) go to medical facilities for treatment of disease, 3) use scientific advancements to grow and prepare their food, 4) use new scientific discoveries in their businesses, and 5) use science in their homes to improve their standard of living.

Proverbs 8 makes it clear that God has used science (wisdom) in all He has done. Psalms 19 and 139 refer to God’s creation, and Romans 1:19-20 points out that science reveals God’s existence through the things He has made. The following verses, Romans 1:21-32, point out that human moral and political choices cause the pain and destruction we see in our world.

Christianity doesn’t need to violate social distancing to worship and to practice our faith. James 1:27 defines true religion, and Jesus made it clear that He is there when just two people come together in His name (Matthew 18:20). First Timothy 6:20 tells Christians to avoid scams and religious claims called science. Ignore the religious anti-science rhetoric and know that God and science are friends. Don’t listen to politicians and religious hucksters and rely on evidence and the message of proven researchers. Join together in prayer and worship in our homes on Zoom, YouTube, Facebook, or whatever method you choose. Rejoice that, through science, God has given us new ways to come together, encourage each other, and glorify Him even in the middle of a pandemic.

Strong Enough to Bend

In 1988 Tanya Tucker had a country song titled “Strong Enough to Bend” that had a great message. In the song, she compared a willow tree to human relationships. She pointed out that willows can survive because their limbs can bend instead of breaking.

Interestingly enough, that concept is present in most living things in the creation. God rarely uses stiff materials in what He creates. On the other hand, humans tend to use rigid materials such as metals, ceramics, dry wood, etc. In your own body, how many stiff materials are there? Bones and teeth are about it. These are components designed for a specific purpose where hardness and stiffness are required. Most things in the biological world are soft, not brittle.

A classic example of the benefit of being soft and not hard is kelp and other marine algae. Those plants live in the violent world of surf. If you have ever surfed, you know the power of waves. I have seen surfboards thrown against rocks, pounded by the waves, and turned into a pile of shredded plastic in a matter of minutes. Kelp live in the surf with one end attached to rocks and the surface of the plant exposed to sunlight for photosynthesis. Kelp can survive because they are strong enough to bend.

Waves produce flows that reverse direction every few seconds. As soon as the plant grows longer than the distance the local water travels between reversals, the additional length of plant material is swept back and forth with the water. The plant literally goes with the flow. Since it moves the same direction as the water and at the same speed, there is no friction between the plant and the water. Kelp can grow to lengths well over 130 feet (40 m). A rigid plant like an oak tree in the surf would be pounded to splinters in a few hours.

Closer to home for most of us, are the leaves of land plants. Take a cardboard tube like a paper towel tube and try to bend and twist it. Then make a lengthwise slit in the tube and try it again. Notice how much easier it is after you cut the tube. The reason leaves have exotic shapes is to allow them to bend and twist rather than breaking in high winds or creating wind resistance that would take down the tree.

This design shows highly complex engineering, and our lives exist because of it. Imagine what would happen if our skin, eyes, ears, stomach, blood vessels, hair, etc. were not made of soft, pliable material. A good sneeze could shatter our face! Our Creator knew that being strong enough to bend was critical for our existence.

How Do Sea Animals Drink Water?

Yesterday we discussed how fish drink water. In the ocean, the problem isn’t water but salt. Ocean fish are designed with specialized gills that support the kidneys in getting rid of salt accumulations that would otherwise pickle the fish. Obviously, not all animals that live in the ocean have gills. How do sea animals drink water?

Albatrosses and petrels are birds that can spend a year or more in the open ocean, but they need to drink water. Whales and seals also do not have land-based water supplies, and yet, like all mammals, they need water to survive. So how do sea animals drink water when ocean water is salty? God’s design of living creatures always includes unusual equipment to enable them to deal with their environment.

In the case of sea birds, they have a set of salt glands in their heads that connect to the bird’s nostrils. The birds drink seawater, but the glands are so efficient that within three hours, all of the salt is removed through the nostrils.

Whales and other aquatic mammals produce urine that has extremely concentrated salt content. By allowing high salt concentrations in the urine to diffuse into the ocean, the salt never reaches toxic levels inside the animal. An interesting sidelight to this is that the milk of these sea mammals is very low in water content. In that way, they conserve water. Milk from seals has only half the water content of lean hamburger.

Everywhere we look in the natural world, we see that a wonder-working hand has gone before. These marvelous designs are not the product of mindless chance. They show an Intelligence who created with purpose and wisdom. When we realize that ocean water has high salt content, we question, “how do sea animals drink water?” God already took care of that.

In Job 38-40, God challenged Job to advance his understanding of God’s power and wisdom by considering the natural things of creation. When Job questioned God’s wisdom and purpose in his personal struggles, he did not recognize the wisdom shown in creation’s design. We too need to look at what God has done and “know there is a God through the things He has made” (Romans 1:18-20).

How a Fish Drinks Water

Have you ever wondered how a fish drinks water? Your first reaction is probably something like, “It opens its mouth.” Like most things in life, it isn’t that simple.

All living things necessarily have some saltwater content in their bodies to keep chemical balance allowing life to exist. The fluids inside an ocean-dwelling fish are only about a third as salty as the ocean itself. The water inside the fish’s body tends to leave by osmotic pressure, which is the tendency of fluids to move through membranes toward higher concentrations. To avoid this loss of water, the fish does simply open its mouth and drink seawater. But that brings large amounts of salt into the fish’s body. The salt concentration would be more than the fish’s kidneys could handle. To aid the kidneys, the gills of ocean fish are designed to expel salt, so the fish isn’t pickled by it.

In freshwater fish, the osmotic pressure is reversed, so the fluids inside the fish are saltier than the water outside. The skin of a freshwater fish is designed so that water seeps in through its skin and gills. Therefore, the fish doesn’t have to drink at all. When a salmon leaves the ocean and enters a freshwater stream, it merely stops drinking. Like freshwater fish, it depends on its skin to bring in its water needs.

Now that you know how a fish drinks water, the next question would be about other creatures that spend their time in the sea. Birds like albatrosses and petrels can spend more than a year at sea, and whales and seals live in the ocean 24/7/365. How can they avoid being poisoned by the salt? We’ll discuss that tomorrow.

God’s design of life includes fitting living things with specialized equipment to survive in every environment. Fish are remarkable creatures specially equipped for the waterworld in which they live.

Complex Human Brain and a 1948 Dodge

When I was a kid, I had a classmate who could take his 1948 car apart so that every part was lying on the garage floor. He could then put them all back together and have the car working in one afternoon. I bought that 1948 Dodge from him, thinking I could do the same thing. However, he understood the design of the engine, and I didn’t. No car can compare to the complex human brain.

As scientists learn about how the brain operates and the magnitude of its component parts, the complex human brain becomes even more amazing. Different parts of the body allow signals to travel at different speeds. Signals travel through your skin at a modest rate of one mile (1.6 km) per hour. Your spinal cord has alpha motor neurons that allow signals to travel at 268 miles (431 km) per hour. That means signals from the extremities of your body can get to the brain almost instantaneously.

The design of this system is hard to fathom. There are roughly 100,000 miles ( km) of nerve fibers in your brain. The minimum number of neural connections (or synapses) in the human brain is 100-trillion. That is about 1,000 times the number of stars in our galaxy. The number of neurons in the human brain is 100-billion. Those statistics only begin to describe the complex human brain.

At our 50-year class reunion, I asked my friend if he could still tear down his car and put it back together in one afternoon. He said that he couldn’t. What’s more, he said that with the complex design of modern cars that enables them to do much more than the 1948 Dodge, he didn’t want to. As I started my 2018 car and looked at all the buttons and sensors on the dash, I understood what he was saying. That old Dodge got me from point A to point B, but it offered none of the creature comforts of today’s cars.

People talk about “artificial intelligence” taking over for human brains. But the brain does far more than just run through a simple path of mathematical logic. Your brain is a complex creation of an ultimate Engineer who built it to do an amazing number of things that we call “living.”

Ants Use Vibratome to Cut Leaves

Yesterday we wrote about leaf-cutting ants that engage in farming activity, which we used to think only humans did. The 1994 Disney movie Lion King started many people thinking about what these ants do. There is another tool leafcutter ants have that is impressive. These ants use vibratome to cut leaves.

Vibratome is sound emissions that alter the structure of matter close to the sound. Biologists use sound waves to prepare specimens to be sliced for microscopic examination. The sound waves cause soft material to become more rigid and, therefore, easier to cut. Ants had used vibratomes long before scientists discovered it.

As we said yesterday, leafcutter ants in the Atta genus slice off sections of leaves and carry them to their nests to feed the fungi they harvest. Researchers have found that as the ants cut, they chirp at a frequency of 1000 hertz. That sound frequency rigidizes soft leaf tissue, making it easier to cut. Vibratome is a technically sophisticated technique and one you would expect skilled technicians to use. Materials science is a relatively new field, and yet ants have it built into their DNA to chirp at a specific frequency as they cut leaves to feed the fungi they eat.

How is it that ants use vibratome to cut leaves? How did they know that it would stiffen the leaves and allow them to make a smoother cut? Scientists further discovered that the vibratome effect does not speed up the leaf-cutting. However, it enables a smoother cutting of the tender leaves, which the scientific report said gives “the most desirable harvest for the ants.”

God created the leaves as well as the ants that use the leaves to feed the fungi they eat. He gave the ants wisdom to use vibratome to cut leaves. The writer of Proverbs reflects God’s wisdom and intelligence in 6:6-8, “Go to the ant … consider her ways, and be wise.”

Ant Farmers at Work

We commonly think of animals as opportunists. They find their food and eat it or store it for future eating. One of the characteristics of humans that distinguishes us from the rest of the animal kingdom is that we prepare an environment that produces our food. Farmers plant seeds and tend the crops by fertilizing, protecting from threats, and watering when necessary. They also make arrangements for future crops. Entomologists are finding more and more cases where insects do these same things. For example, ant farmers work together to produce their food.

In Fiji, a plant called Squamellaria grows in a cluster with jelly-bean shaped bubbles inside. The opening into the clusters is just the right size for the Philidris nagasau ant to get into the bubbles. As the bubbles send out shoots, the ants defecate inside the cluster, fertilizing the plant. When the plant blooms, the ants eat the nectar it produces. The ants then plant the seeds where new clusters can grow.

Another family of ant farmers is the Atta genus. In their farms, they grow a fungus species that they nourish with leaf cuttings. After cutting off leaf sections, worker ants carry them back to the colony. As the workers transport the leaf cuttings, others ride on the leaves to protect against a parasitic fly species. You might call that pesticide.

At the colony, other ants pulverize and defecate on the leaves to make them ready to nourish the fungi. The ants can’t eat the leaves, but the fungi are their food, and only one fungus species is edible. If another fungus species develops, the ants produce a toxin, which destroys only the invading fungus. This is herbicide use at its best. The Atta ants inspect the fungus several times a day, tending it carefully. The system is so efficient that one Atta nest can grow enough fungus food to feed seven-million resident ants. In the process, the ant colony produces fertile soil that promotes plant growth.

If you saw the 1994 Disney animated Lion King movie, you saw Atta ant farmers at work. Remember that fungi are not photosynthetic. No sunlight is needed for Atta ants to grow their food. They simply carry in the nutrients for the fungi to grow, and then they eat the fungi. We do the same thing with much of our meat, providing plant material for chickens or pigs to eat, and then eating the animals that we fed. In the case of the ants, they eat only one food, which simplifies farming enormously.

We know it takes incredible planning and design to manage a farm. No chance process produces most of the foods we eat. It requires meticulous planning and careful application of fertilizers, pesticides, and herbicides. As scientists study insect farming, they see a design that is carefully and intricately produced.

Data on the ant farmers came from Science News, April 25, 2020, pages 16-20. The subtitle of the article is, “Could our agricultural role models have six legs?” This reminds us of the challenge in Proverbs 6:6-8: “Go to the ant … consider her ways, and be wise. She has no guide, overseer or ruler but provides her food in the summer and gathers her food in harvest.” The title of the article is “The First Farmers.” We might amend that to be “God’s First Farmers.”

Christian Concept of Hope

We read in 1 Corinthians 13:13 “And now abides faith, hope, love, these three. But the greatest of these is love.” How can hope be listed as a foundation of being a Christian? The answer is that the Christian concept of hope does not mean “wish.”

The lexicon tells me that the word translated hope literally means to expect, to look for, to await. It is not to wish for something to happen. In Romans 4:16-22, Paul speaks of Abraham being the father of many nations, and he says Abraham “believed in hope”? Does that mean Abraham hoped that God did not lie to him about his future? That is absurd. Verse 19 tells us that Abraham believed and was not weak in faith. Abraham’s hope was looking for what was about to happen.

The Christian concept of hope does not depend on what we possess, what we can do for ourselves, nor what any other human may do for us. We don’t hope (wish) that we will go to heaven. We look forward to it. Read 2 Timothy 4:6-8 and see if you think Paul expresses the WISH that heaven awaits him. He looked forward to heaven.

Over and over, we see this Christian concept of hope in the Bible. In 2 Corinthians 1:10, Paul wrote, “On Him we have set our hope that He will continue to deliver us.” He did not say we wish He could or would. Colossians 1:27 speaks of the “hope of glory.” Not that we wish it was, but that we are waiting for it. In 1 Thessalonians 5:8, Paul refers to Christians and repeats the message of our key passage in 1 Corinthians 13:13. He wrote, “Let us be sober, putting on the breastplate of faith and love; and for the helmet the HOPE of salvation.” Notice that this is a covering for the head, the most sensitive part of our bodies. Notice it is not the “wish of salvation.” It is “the hope of salvation.” It is the expectancy, the things we are waiting for.

In Hebrews 6:17-20, we see this stated again. Read the passage. Notice that there are two unchangeable things. One is that God cannot lie. The other is that our HOPE is an anchor for us. That is our promise of salvation. In Romans 15:13, we see God referred to as the “God of HOPE.” The God of promise. The God we can look forward to. Not the God of “maybe” or “possibly” or “could be.” Things like the current pandemic can be approached fearlessly by Christians because we have the assurance that something better is coming – guaranteed!!

Early Christians Confronted Plagues with Faith and Courage

We hear a lot about the current virus struggle and references to the idea that this is a first-time event. That may be true for those of us living in America, but plagues have been the scourge of humankind throughout recorded history. We recently saw a writing by the early Christian historian Eusebius that tells us about how early Christians confronted plagues. He referred to a report from an elder in the Church named Dionysius around A.D. 260. Dionysius was writing about the plague in Alexandria. Here is a quote from part of his letter to Eusebius:

“Most of our brethren showed love and loyalty not sparing themselves while helping one another, tending to the sick with no thought of danger and gladly departing this life with them after becoming infected with their disease. Many who nursed others to health died themselves. The best of our own brothers lost their lives in this way – some elders, deacons and laymen – a form of death based on strong faith and piety that seems in every way equal to martyrdom.

“All things are filled with tears, all are mourning, and on account of the multitudes already dead and still dying, groans are heard throughout the city… There is not a house in which there is not one dead. Despite afflictions we Christians rejoiced in the peace of Christ which He gave to us alone… Most of our brethren by their exceeding great love and affection, not sparing themselves and adhering to one another, were constantly superintending the sick, ministering to their wants without fear and cessation, and healing them in Christ.”

This quote appeared in Action! magazine, May 2020, page 2. John Reese, the president of World Bible School which publishes Action! added a comment. He said that the existence of hospitals was an early Christian innovation to improve the ability to serve those struck down by the pandemic of their day. We can learn much from how early Christians confronted plagues.

Relativity and Light Speed

Relativity and light speed present a confusing concept in physics. My students always came into the physics class with prejudice based on what their family had told them. The relatives scared the students into thinking physics class was going to be hard. I always began the year by telling the students that physics was the easiest class they would ever take as long as they learn to speak algebra.

One year, a student enrolled in my physics class who had escaped Viet Nam and spoke virtually no English. The guidance counselor questioned how the student could handle my class with the language handicap. The young man smiled and said through his interpreter, “But I speak excellent algebra!” That was true, and he was my best student that year. Einstein’s theory of relativity is a physics unit that invokes fear in many minds, but it’s easy to understand if you know a little algebra.

The problem is not understanding relativity and light speed. The problem is believing it. Relativity begins with TWO BASIC POSTULATES:

THE FIRST is that the laws of physics are the same no matter where you are or what you are doing. If you are sitting in your chair reading this, all the laws of physics work very well. When you drop an object, it falls in accordance with the laws of motion. If you were in an airplane traveling near the speed of sound and you drop the same object, it would fall the same way as it did when you were sitting still.

THE SECOND postulate tells us that the speed of light is a universal constant. This one is easy to understand, but very hard to believe. Suppose I were in a rocket traveling toward you at half the speed of light. If I turn on my headlights, the light beam will travel at the speed of light. You are sitting still and measuring the speed of the light beam. What would your measurement be? You might be tempted to say, “The speed of the rocket, 0.5 times light speed, must be added to the speed of light. The answer would be 1.5 times light speed.” What Einstein’s postulate says is that you would measure it to be the speed of light–186,000 miles or 300,000,00 meters per second. That’s because the speed of light is a constant, independent of the motion of the light source or the observer.

Light speed is designed to be a universal constant according to Einstein relativity equations. You say, “How can that be?” According to Einstein, time is a created thing that depends upon the motion of the observer. As you go faster, time slows down. The algebraic equation is that the time you experience (t’) equals the time you would experience at rest (t), divided by the square root of 1 minus the velocity (v) squared divided by the speed of light (c) squared. Notice that the velocity cannot be higher than the speed of light. If it were, the denominator would be the square root of a negative number, which is not possible. If you don’t understand the equation, understand that time is not a fixed thing. It changes with velocity. The faster you go, the slower time passes. At light speed, time would stop.

Science fiction writers have suggested that this is a way to build a time machine. That won’t work, because time doesn’t reverse. Since the speed of light is always the same for all observers, time gets slower and slower but never stops. This is not wild speculation. Experiments at very high speeds in particle accelerators have verified what we have briefly sketched here.

Not only does this change our understanding of time, but it gives us a new understanding of space and mass. This knowledge helps us understand not only the creation but also the wisdom and design built into it. Everywhere we look, we see that a wonder-working hand has gone before us. Tomorrow we will look at the implications of relativity and light speed in Einstein’s Theory of Special Relativity.
