What Is Light?

What Is Light?
A question that scientists cannot fully solve is the nature of light. What is light? Is it a wave or is it a particle?

Light has wave properties. It travels in straight lines, but it can be reflected from objects like mirrors, or refracted as it travels through objects like water or glass. Different frequencies of light waves are bent in varying amounts by a prism to show the colors of the spectrum. Light, like sound waves, can travel through gases (air), through liquids (water), or through solids (glass).

But light can also do something that waves normally cannot do. Light can travel through empty space. Because of that and other properties of light, we say that light consists of particles called photons, which act as if they have mass. Photons can knock electrons out of crystals in what we call the photoelectric effect. That’s how solar panels generate electricity from sunlight. So light in motion seems to have mass since it can pass through a vacuum or knock electrons out of their orbit. However, when we stop light, it has no mass. If you shine a light on an object, the light doesn’t make the object any heavier.

What is light? While science ponders that question, we use light every day, and we couldn’t live without it. The question of how light can have properties of both a wave and a particle has baffled scientists for centuries. Even though that answer to that question may never be fully understood, we continue to enjoy and use it every day.

We can see that the simple phrase “let there be light” (Genesis 1:3) is an incredibly complex command.

Troposphere and Breathing Comfort

Troposphere and Breathing Comfort
Earth’s atmosphere is incredible! There are three primary layers of the atmosphere, and we live in the bottom layer called the troposphere. It extends as high as about 33,000-43,000 feet (10-13 kilometers). This layer is where we have breathable air. Above the troposphere is the stratosphere and above that is the mesosphere.

The troposphere is not only where we have air we can breathe, but it is also where we have weather and clouds. In the stratosphere, the air is not dense enough to supply us with sufficient oxygen, but it is relatively peaceful with little turbulence. In the early days of commercial airplane flight, because of turbulence in the troposphere, many people became airsick. However, planes could not fly above the troposphere because, among other problems, the low air pressure in the stratosphere would create a lack of oxygen for breathing.

That changed in the 1930’s when the Boeing company designed the first successful airplane with a pressurized cabin. They called it the “Stratoliner.” It could fly above the turbulence and still provide breathing comfort. Today commercial passenger planes fly in the lower stratosphere for cruising comfort, with pressurized cabins for breathing comfort.

When the weather on Earth becomes turbulent, we sometimes complain, but we can be thankful that the Designer of the Earth gave us a pressurized zone. With each breath we take, we should be thankful.

International Dateline Where Days Divide

International Dateline Where Days Divide
Because the Earth is always turning on its axis, we have periods of day and night. To establish consistent times for daylight and darkness, humans have divided the Earth into 24 time zones. At one point we call the International Dateline, the days divide.

As you travel around the world east to west, the time becomes earlier. As you go west to east, it becomes later. In the United States, the time on the west coast is three hours earlier than the time on the east coast. At some point on the Earth, the time has to change by 24 hours. We call that the International Dateline (IDL) and it runs from pole to pole through the middle of the Pacific Ocean. A new day, or a new year, always arrives first on the west side of that line. Then it progresses around the Earth, hour by hour until it returns to the east side of the IDL.

The Earth always has day and night at the same time because it’s a rotating sphere. People in antiquity didn’t understand that. Also in ancient times when people did not have electric lights, they worked only during the day and slept at night. However, 2000 years ago Jesus talked about an event that will take place in an instant, but he said that it will be daytime and it will be nighttime. He also said that some people will be working (daytime activity) and others will be sleeping (nighttime activity) when the event takes place.

You can read the words of Jesus in Luke 17:30-35. How did He know that day and night take place at the same time? I think it was because he was more than a man. In fact, I believe He created day and night. (See John 1:1, 2, 14.)

Circadian Rhythm of the Biological Clock

Biological Clock and Circadian Rhythm
Living things, both plants and animals, have a biological clock that is extremely important for survival. The human master clock is located in the hypothalamus of the brain in a tiny region called the suprachiasmatic nucleus (SCN). The SCN controls what is known as the circadian rhythm, a 24-hour rhythm of the body.

The SCN interacts with many regions of the brain to control sleep, hormone levels, alertness, body temperature, digestive activity, immune functions, and other systems. It coordinates the various rhythms of the body to keep us going through the day. This biological clock works in many ways that we don’t even realize.

Specialized cells in the retina of the eye connect directly to the SCN. When the eye senses light, the SCN receives the message and starts body process going by telling the various systems what to do and when. When you wake up in the morning, the clock signals enzymes to start flowing for your first meal. Hormones raise body temperature and blood pressure so that you can face the day.

During the day, the biological clock starts various chemicals and hormones so they will be available and functioning when they’re needed. Therapeutic medicines work best when taken at certain optimum times according to the biological clock. At night the circadian rhythm in the SCN sends a message to the pineal gland to produce the hormone melatonin making us sleepy.

This is a highly-simplified summary of an amazingly complicated system. Complex systems like this don’t happen by chance indicating that this is another evidence of design. Day and night, months and seasons regulate the systems of humans and all other creatures. Genesis 1:11 tells us that God made the Sun and Moon to “mark seasons and days and years.” Those simple words contain profound truths that we have only begun to understand.

Honeybee Engineering

Honeybee Engineering
Bees are master engineers of the storing of dense fluids. Their fluid is honey, and they store it in a way that shows excellent honeybee engineering.

Worker bees gorge on honey and excrete slivers of wax. Other workers take that wax and position and mold it into a column of six-sided cells. The bees cluster to keep the temperature of the wax at 35 degrees C (95 degrees F) so that it’s firm but malleable. Each wax partition is less than .1 mm thick with a tolerance of .002 mm. The cell walls must be at a 120-degree angle in relation to each other to make a lattice of regular hexagons.

There are only three regular polygons which pack together snugly without leaving gaps–equilateral triangles, squares, and regular hexagons. The perimeter of a hexagonal cell that encloses an area is less than that of a square or a triangular cell making it the most economical shape. Using the same quantity of wax, hexagonal cells can hold more honey than square or triangular cells. Mathematicians have tried other options, such as using curved sides or a mixture of polygons. They have confirmed that curved polygons could not do as well as straight-line hexagons. Mathematicians can’t beat honeybee engineering.

How do the bees keep the honey in the cells? They tip the cells upward at an angle of 13 degrees from the horizontal. That is precisely the angle needed to stop the honey from dripping out. There is one more problem. How can the bees seal off the bottom of the columns? A flat bottom would not do. Bees construct the base with three, four-sided diamond shapes that meet in a point. Two rows of cells are placed back-to-back and offset so that they interlock. With the cells backing up each other, only one layer of wax acts as the bottom for both cells. Mathematicians have proven that the angles of the diamond-shaped cell bottoms (109.5 and 70.5 degrees) give the maximum volume for storage.

It’s difficult to believe that the honeycomb structure is an accident or the final product of trial and error. Mistakes are usually lethal or at least result in a loss of vital energy resources. Honeybee engineering has fascinated and amazed philosophers and mathematicians since the time of ancient Greece. We think the honeybee engineers learned the principles of structural math from the Master Engineer.

Why Venomous or Poisonous Animals?

Why Poisonous Animals? Eastern Coral Snake
There are 2700 known species of snakes on this planet. Of all those, 412 species, or 15.2%, are venomous. Five hundred thousand people are bitten every year, and 40,000 of them die. People are afflicted by poisonous lizards (two varieties), frogs, salamanders, and a variety of toxic insects. This brings up the question of why venomous or poisonous animals exist if a loving God made all things.

If you or someone you know has suffered an attack by one of these animals, you know that even when it is not deadly, it’s still a very unpleasant experience. The skeptic and even the non-skeptic is moved to ask why God would create a reptile or amphibian that could cause such terrible discomfort to humans. Why should an innocent child die because of picking up a pretty ribbon that turned out to be a coral snake?

If you have experienced an encounter, no canned explanation will make the pain and loss go away. But can we make any sense of why venomous or poisonous animals exist?

We must first begin by recognizing that God may not have created these animals as they are today. God did not create many animals (dog and cattle breeds for example) as they are today. They have changed over the years. It is possible that the same is true of poisonous animals, and their original ancestors may not have been deadly. However, the complexity of the poison systems in reptiles and amphibians seems to make this explanation a little imaginative, if not impossible. Even if true, it does not remove God’s awareness of the situation.

A better answer to this question of why venomous or poisonous animals exist lies in the wisdom and planning of God. The Bible says we can know God exists and see His wisdom by looking at the creation. (See Romans 1: 19-23; Psalms 19: 1.) The more we learn about the creation, the more we see God’s design.

One thing we have come to understand is the need for balance in ecosystems. We know that all living things serve a purpose in their natural setting. Animals and insects eat plants which keep the plants from crowding themselves out. Carnivorous animals keep the plant-eaters from wiping out their food supply. Because animals do not fear death as we do, the system is not as cruel and as callous as some would have us believe. In a balanced system, things generally function smoothly and efficiently.

One of the critical factors in maintaining balance is the survival of reasonable numbers of all species. Most reptiles and amphibians are soft-bodied, slow, and generally vulnerable. Camouflage protects some, but the venom or poison glands of others are necessary to do the job. Not only does this protect that animal, but any animals that look similar. Venom also helps the animals catch their food. Rats and mice are the primary food source of many snakes, but without the venom, the snakes could never catch them. Very few venomous snakes or poisonous animals of any kind will attack a human. Most bites occur when a person molests an animal. The obvious purpose of the poison is defense and obtaining food. Accidents do happen, but the poison was not given as a device to be used on humans.

Another important factor is that venomous and poisonous animals provide medicines that we cannot secure from any other source. Medicine from snake venom stops the agents which cause rheumatoid arthritis. There are many other examples of ways science has found to use the poisons from animals.

We can see that there are reasons why venomous and poisonous animals exist. Venomous animals do not prove that God didn’t thoughtfully and intelligently design the creation. We sometimes have to look a little more closely to see the ultimate wisdom of the Creator.

How Pharaoh’s Heart Was Hardened

How Pharaoh's Heart Was Hardened
Yesterday we began to consider Exodus 4:21 which says that God hardened Pharaoh’s heart. What did God mean when He told Moses that He would harden Pharaoh’s heart? Can we see how Pharaoh’s heart was hardened?

Pharaoh was a political leader whose kingdom was under siege. He would obviously be on an emotional and intellectual roller coaster. God simply allowed Pharaoh to see the cost of letting the slaves go. God hardened Pharaoh’s heart by strengthening his resolve as a political leader to realize what was happening. It made Pharaoh strong intellectually and emotionally, but that doesn’t mean he was a robot with no choice in the matter. He would not want his people to see him as a weak, condescending ruler giving in to a bunch of slaves over things his own court magicians could do. At least in the beginning, Pharaoh would become strong, hard, and determined to stop Moses. That is how Pharaoh’s heart was hardened.

Let me give you a personal parallel. Many years ago my wife Phyllis and I made arrangements to adopt a child. After a month or so, we saw that the child had many congenital problems including blindness, cerebral palsy, schizophrenia, a form of muscular dystrophy, and mental retardation. Our awareness of all of this came one step at a time beginning with blindness and ending seven years later with a diagnosis of muscular dystrophy and schizophrenia. By law, the adoption agency was obligated to take the child back. However, we could choose to go ahead with the adoption.

My heart and my wife’ heart softened and hardened. Mine more than hers. My atheist parents tried everything to make us give up the child. They even threatened the agency with a lawsuit if they didn’t forcibly take him from us. My fellow teachers almost universally told me I would be crazy to keep the child. Close friends showed me what keeping him would mean financially, socially, and professionally. My heart was hardened to the point that one afternoon I put him in the car seat and prepared to return him to the adoption agency.

I started the car and then decided to pray about what I was doing. At that point, a Christian brother walked up to the car and began to talk about what might be possible. Could this baby be a messenger to the blind? Could I walk down the street 20 years in the future, see a blind man and wonder if it was the child I gave up. I realized my heart had been hardened. It was not hardened by God, but by all of the world that surrounded me.

Pharaoh’s case was the reverse of mine. His heart was softened by the plagues that challenged his power and political position. God had allowed him to see the cost of giving in to Moses and thus giving in to God. That was how Pharaoh’s heart was hardened. God hardened him intellectually and emotionally to make him strong in the eyes of his people. Pharaoh could have avoided the calamity of hard-heartedness. But selfishness, greed, and power struggles make people do foolish things. Both the Pharaoh and I eventually had our hard hearts softened to the point of doing the right thing. But the cost was high for both of us.

God Hardened Pharaoh’s Heart

God Hardened Pharaoh's Heart
One of the interesting studies of the Old Testament is the account of the Egyptian Pharaoh, Moses, and God. In Exodus 4:21 we read that, “The Lord said to Moses when you go to return to Egypt, see that you do all those wonders before Pharaoh, which I have put in your hand: but I will harden his heart, that he shall not let the people go.” What does it mean that God hardened Pharaoh’s Heart?

There are numerous cases throughout the Bible where the hardening of the heart is an issue. Is God making Pharaoh a robot with no choice but to make the catastrophic decision not to allow the Israelites to leave? Does God make a person’s heart hard and then send them to hell because of their hard heart? How can that picture be harmonized with the concept of a loving and kind God who wants everyone to be saved (2 Peter 3:9). If God hardened Pharaoh’s heart, what does that mean and how did it happen?

Like a lot of questions about God and the Bible, we can answer this at least in part by a careful study of the meaning of the biblical words. The first word we need to understand is the word “heart” which is the Hebrew leb or lebab. In 1 Samuel 25:37 we read about a man named Nabal, and we are told his heart died within him and he became as a stone. In 2 Samuel 18:14 we see Joab thrusting three darts through the heart of Absalom. In 2 Kings 9:24 Jehu shoots an arrow at Jehoram and hits him in the heart. The word heart is used in a physical sense 29 times. However, most biblical uses of the word “heart” do not involve the organ that beats in our chest.

Proverbs 23:7 gives us a different use: “For as he thinks in his heart, so is he. He tells you to eat and drink, but his heart is not with you.” The Bible uses the word heart 257 times referring to personality characteristics, and 166 times it refers to states of consciousness. First Samuel 1:8 says, “Hannah, why do you weep, and why is your heart grieved?” Heart refers to intellectual activities such as in 1 Kings 3:9 where God gave Solomon an understanding heart. We find the word used 195 times referring to volition or purpose. In 1 Samuel 2:35 we read, “And I will raise me up a faithful priest, that shall do according to that which is in my heart and my mind.”

The other keyword to understand in this discussion is the word “hardened” which is the Hebrew chazaq which means “to make strong.” Normally this word describes things that make us insensitive. Hebrews 3:13 tells us that we can “be hardened through the deceitfulness of sin,” and verse 8 and 4:7 indicate humans choose to do the hardening. Job says he was hardened in sorrow in Job 6:10. Daniel 5:20 talks about a king’s heart being lifted up and his mind hardened by pride. Psalms 95:8 indicates we can harden our own hearts and references the Israelites in the wilderness as an example. Nehemiah talks about Israel hardening their necks and their rebellion against God.

So what does Exodus mean when it says that God hardened Pharaoh’s heart? We will examine that question tomorrow.

Grand Canyon Formation

Grand Canyon Formation
As we told you before, this is the week of the 2018 Canyonlands Tour. We mentioned the plaque at the Grand Canyon watchtower with the verse from Psalms. Today, we would like to share with you a video segment from a previous field trip to the Grand Canyon. In the video, geologist and teacher John Clayton uses the diagram shown above as he describes the layers of the Canyon and the various processes that formed them. The Grand Canyon formation processes are complex and involve God’s work through natural forces over a vast span of time.

Canyonlands Tour 2018

Canyonlands Tour 2018

This week John Clayton is with a group of people on what we call the Canyonlands Tour. Many times over the years John has taken groups of people to visit the Grand Canyon, Bryce Canyon, and Zion Canyon, as well as other locations in northern Arizona and southern Utah.

The Canyonlands Tour is not just a sightseeing trip. It’s an opportunity for Christians to learn about how God has worked to create those “natural wonders.” John uses his knowledge of geology to explain the many interesting and beautiful features of the “canyonlands” area. Some people try to explain the Grand Canyon by “flood geology.” John explains what the real science of geology actually tells us about the formation of that remarkable Canyon.

With the assistance of Alan Doty who has hiked the canyons many times, the Canyonlands Tour is always an interesting and educational experience. One of the places on the agenda is the “desert view” area overlooking the Canyon. That is the location of a watchtower which visitors can tour.

On a level of the tower, there is a wall which has a plaque attached as you can see in the picture. The plaque contains the words from Psalm 66:4. It says, “All the earth worships Thee; they sing praises to Thee, sing praises to Thy name.” That plaque has been there for years. With atheists demanding the removal of any acknowledgment of God on public property, perhaps the only reason those words are still there is that some might interpret the “Thee” and “Thy” as referring to the Grand Canyon.

However, those pronouns do not refer to the Canyon, but to the One who created it. The process of creating the Canyon was no small feat. It did not happen in one flood. The people on the Canyonlands Tour will learn something about the processes that science still does not fully understand. In the meantime, there are those who say the Grand Canyon disproves God. It does not. It only invalidates a false interpretation of the Bible which many have adopted.

It’s too bad the people who placed that plaque didn’t include verse 3 as well. It says, “Say to God, ‘How awesome are your deeds! So great is your power that your enemies cringe before you'” (NIV). I am sure that there have been some atheists who have cringed when they read the words of that plaque. I suspect that sometime an “offended” atheist will demand its removal. However, nobody can remove the Grand Canyon and the testimony it gives to the power and glory of God.
