Leaf Designs to Preserve Trees

Leaf Designs to Preserve Trees
We live in a part of the world where there are many trees. We also experience heavy winds that frequently blow down human-made structures. It is interesting that healthy trees are almost never blown down. When you stop to think about it, you would expect trees to be major victims of high winds. That is not the case, and it is due to leaf designs to preserve trees.

To survive strong winds, trees need two things. The most obvious is structural support–strong, flexible branches, sturdy trunks, broad bases, and good root anchorage. A more subtle requirement is leaf designs to preserve trees. Leaves must have minimal wind drag. A fluid, such as air, flowing around an object generates drag. To minimize drag requires some streamlining to reduce the amount of friction between the fluid and the object. A highly streamlined object will usually be gently rounded upstream and elongated and pointed downstream.

For healthy trees, the leaves offer the most surface area and thus the most drag. Trees most commonly blow over when in full leaf, so leaf design is critical to the survival of the tree. Different trees have different design features, but all of them are designed to avoid destruction in a wind storm. American holly leaves have a method that involves the leaves being able to flatten themselves against each other. When the wind becomes strong, the leaves turn and lie flat significantly reducing the drag.

Tulip tree leaf design allows the leaves to roll up when the wind gets strong. The blade of the leaf points away from the stem. As the wind blows against the leaf, it forms a cone pointing upwind at the stem. The blade forms the broad area of the cone away from the wind direction. The higher the wind, the tighter the cone and the less the wind resistance. Black locust leaves similarly roll together to produce a cylinder.

Each of these designs depends on the properties of the leaf. If the leaves were too stiff, they could not assume the right geometry. The flexibility of their stems has to be high, and the surface of the leaf must be carefully designed and restricted. You can argue that natural selection does all designing and that given enough time it will select the proper shape. But remember that changes in climate mean you don’t have infinite time to apply the process.

God’s engineering wisdom gave us leaf designs to preserve trees. The leaf design allows the longest season for each tree. Sit in your backyard on a breezy day and watch what the leaves do to preserve that tree you prize so highly.

Hamburgers Without Beef

Is Hamburgers Without Beef in Your Future?
There has been a lot of hype about red meat and its potential damage to our health. The FDA held its first public hearing about growing meat in the laboratory instead of using cattle–or for that matter fish or birds. The challenge is to produce hamburgers without beef.

One process that scientists are experimenting with involves growing “cultured meat” in the laboratory from real animal cells. The other idea is to create “meat” from plants with the protein and taste of real beef hamburgers without beef. Beef production is the top emitter of greenhouse gases, and growing beef from cows emits over 100 times more greenhouse gases than plant material would emit to produce the same amount of meat. Patrick Brown of Impossible Foods in Redwood City, California says “Animals happened to be the technology that was available 10,000 years ago for making meat. We stuck with that technology, and it’s incredibly inefficient by any measure–and destructive”.

When Nicolas-Joseph Cugnot introduced the first combustion steam-powered vehicle in 1771, it offered significant advantages over the horse. In 1898 urban planners in New York were concerned about the 50,000 tons of horse excrement that 175,000 horses in New York City were producing every month. Ten years later Henry Ford introduced the Model T which eventually eliminated the problem. How long will it take for plant-produced beef to solve the environmental and health problems caused by the use of cows to produce food? The beef industry is huge in America, hamburgers without beef are likely to be available in Europe and Asia before they are accepted here.

Some people believe that Christians cannot eat manufactured meat on religious grounds. Even those who go back to the meat prohibitions of the Old Testament will find no support for forbidding plant-produced hamburgers. In Genesis 9:3, God told Noah that he could eat of any “green plant,” but the law placed massive restrictions on eating animal-based protein. In 1 Corinthians 8:8-13 and in Romans 14:1-5 Paul expressed concern over the influence of Christians who because of their freedom to eat anything, might pose a problem for those who don’t understand that food is not a religious issue. Romans 14:17 summarizes this by saying, “The kingdom of God is not about meat and drink; but righteousness and peace…” In 1 Corinthians 10:25-27 Paul tells Christian to eat whatever is set before them “asking no questions.”

The silly aspect of religious concerns about eating manufactured foods is that we already do it. Think of the list of manufactured foods that we eat now. They include artificially produced fruits and vegetables such as tangelos, and hybrid apples, corn, and tomatoes. Other food substances include margarine, soy milk, artificial sweeteners, butter spray, etc. We copy God’s design of the foods we eat to enlarge the food supply of the planet and avoid waste.

Food chemistry is highly complex, but the more we understand the creation, the closer we get to the Creator. Let us thank God that we don’t go to bed hungry. Also let us thank God He has given us the ability to meet the needs of the hungry as we understand how we can produce and use these new foods, including hamburgers without beef.

Ultimate Fluid Machine

Ultimate Fluid Machine
Imagine designing a fluid system to maintain a complex machine. The system must be able to flush any waste from all parts of the machine. It must be able to supply energy to every part of the machine, even though those parts operate in different ways. It must be the ultimate fluid machine.

The machine must function in an environment where getting enough air for it to run is an issue, so your fluid system must carry oxygen to every nook and cranny of the machine. The fluid system must also transport materials that can fight any invader, and if there is a leak in the fluid system the system must be able to flush the opening and seal the leak immediately!

I suspect that by this time you have surmised that the complex machine we are talking about is your body, and the fluid system that maintains your body is the vascular system. To do the things we have listed (and many more things we have not included) your body has 60,000 miles of blood vessels according to the National Institutes of Health and NASA. That means that if we could take all of the blood vessels out of your body and attach them end to end, the resulting series of vessels would go all the way around the Earth more than two times.

The ultimate fluid machine exists in every human on the planet. Simply knowing that emphasizes the accuracy of the clear description of Psalms 139:14, “I will praise thee, Lord, for I am fearfully and wonderfully made. Marvelous are your works…”

How Many Bugs Are in Your Home?

How Many Bugs Are in Your Home?
Would you like to guess how many bugs are in your home? In the fall of 2017 researchers from the California Academy of Sciences published a survey of the bugs in 50 homes in and around Raleigh, North Carolina. The researchers took 10,000 samples from basements, bedrooms, kitchens, and attics. They identified 579 species from the 304 families of arthropods known to science. Arthropods include insects, mites and, spiders.

The researchers found ants, carpet beetles, gall midges, and cobweb spiders in 100% of the homes. In many of the houses, they found booklice, dark-winged fungus gnats, cellar spiders, scuttle flies, and dust mites. Misha Leong who was the lead author of the study says that most homes contain hundreds if not thousands of individual arthropods.

It is interesting that as people move toward buying organic and buying in bulk, they are increasing the bugs in their homes. Indian meal moths, for example, can contaminate oatmeal or chew through a sweater. They lay eggs in our food and closets, and the larvae chew through packaging leaving a mess of silk and frass (waste) behind. If we use the food quickly enough we eat the eggs, and since they don’t hurt us, we don’t even know they are there.

The reality is that we have and will always have lots of bugs in our homes. Many of them are beneficial to us. Booklice, for example, eat fungi and mold. Spiders eat insects and other harmful agents including flies and mosquitoes. Harmful spiders like the black widow and brown recluse are rare. Studies have also shown that many of our chronic diseases are related to our failure to be exposed to biological diversity. Leong says, “Rooms with more kinds of arthropods may be healthier rooms.”

God did not place us in a sterile world. The more we learn of what we live with each day, the more we realize the complexity of life. Living with bugs is essential to our long-term survival. How many bugs are in your home?

Genesis 1:1 and the Creation Week

Genesis 1:1 and Zion Canyon
Because it was not God’s purpose to give details of the creation of the universe, Genesis 1:1 covers it in one sentence. “Reshith Elohim bara shamayan erets.” Those are the Hebrew words translated: “In the beginning, God created the heavens and the earth.” This is a historical statement which says there was a beginning to everything in space and on Earth. Those few words tell us that God was the cause of the creation. The creation included a planet with everything that we would need to exist and flourish–carbon, oxygen, water, coal, oil, nitrates, etc. “Erets” refers to a functional planet–not to a blob of gook.

As we drove through the canyonlands last month (see earlier posts), we saw how God prepared the Earth and the physical, chemical, and biological agents He used. It is interesting to see that dinosaurs, as well as many microscopic forms of life, were the gardeners who allowed all of this to happen. Without dinosaurs, there would have been no agents to process the giant plants of that day and spread their seeds. Without tiny diatoms, there would have been no agents present to form the oil and other fossil fuels that we need. Notice that Genesis 1:1 is untimed and undated! How long did it take? When did it happen? The Bible doesn’t say.

In Genesis 1:2 we see that the earth needed to be formed. The word translated “earth” is the same Hebrew word “erets” found in verse 1. This second usage is clearly different, however, because Genesis 1:9-10 indicates that God separated this earth from the water, meaning that it refers to the earth people live on, not planet Earth.

In the following verses of Genesis, the “days” of the “creation week” give specific explanations of the origin of the plants, water creatures, cattle, goats, sheep, chickens, and ducks the ancient Israelites knew. Each Hebrew word refers to known and domesticated animals, not unknown animals. Days are used to provide continuity to the sequence in which God created life. How long those days were, whether they were consecutive or had long time-periods between them can be debated endlessly.

The fact is that the first verse describes the creation made by God with the things humans would need to survive on Earth. As we said, that first verse is untimed and undated. All of the studies of geologists and biologist as to how those resources were produced are covered in that one verse of Genesis 1:1. The creation week is a description of the actual production of humans and their domesticated animals.

On our trip into the canyonlands, we saw the power, wisdom, and planning God used to allow us to exist. Proverbs 8 presents wisdom as the causal agent of creation–not blind mechanistic chance. Theological claims that create conflict between God’s word and the display of His wisdom and design are due to human error, not to the Creator.

Conflict Between Scientific Evidence and the Bible

Conflict Between Scientific Evidence and the Bible- Petrified Forest
For the past two days, we have been reviewing some of the things we saw and learned on the Canyonlands Educational Tour of last month. We explained our approach to the physical evidence of creation and all of the Scriptures that tell what happened. We say that the two sources must agree. If the same God who gave us the Bible also did the creating, they cannot disagree. If there seems to be a conflict between scientific evidence and the Bible, we either have bad science or bad theology or both. And there has been plenty of both.

There has been great conflict between the physical evidence that the Earth is very old and denominational interpretations of the Bible’s creation week. As we visit the Grand Canyon, Bryce Canyon, Zion National Park, the Painted Desert, and the Petrified Forest, the massive amount of evidence that the Earth is much more than 6,000 years old becomes obvious. So how do we resolve this apparent conflict between scientific evidence and the Bible? If we are not locked into those denominational belief systems, we can take the Bible literally. By that we mean, look at who wrote it, to whom they wrote it, why they wrote it, and how the people it was written to would have understood it.

Genesis was written in the style of Hebrew poetry to all of humanity–those living in the days of Moses as well as those living in the 21st century. We cannot expect the account to deal with quantum mechanics, because the people of Moses’ day would not have understood it. The animals described in Genesis are animals that people of Moses’ day would know. Don’t look for duckbilled platypuses, echidnas, penguins, or dinosaurs in the Genesis account. Don’t look for descriptions of stellar production of heavy elements or evolution of stars or even continental drift.

We could list hundreds of things that you would not expect in the biblical account because the ancient Israelites would have no way to understand them. Furthermore, there would be no reason to give such details, and the Bible would be too heavy to carry. For that reason, the Bible begins with the single sentence: “In the beginning, God created the heavens and the earth.” That sentence prepares the reader for a simplified description of the actual production of humans and their domesticated animals on the planet we call home. There is no conflict between scientific evidence and the Bible when taken literally. We will have more on that tomorrow.

God’s Engineering Skills

God's Engineering Skills at Sunset Crater
Yesterday we began to tell you about last month’s Canyonlands Educational Tour. It was a week of learning about how God works. In the canyonlands area, we can see God’s engineering skills.

Our trip was a bus tour with 50 people participating. We departed from Flagstaff, Arizona. That area allows us to study the basic rocks from which all other rocks were made, and that is volcanic material. Our analysis of elements in space and the minerals in Earth’s crust show us that all rocks are made of materials found in the interior of the Earth. For example, granite is made up of quartz which breaks down into sand and makes sandstone. Orthoclase is another constituent of granite, and it weathers to produce clay which is a major part of shale. Visiting Sunset Crater (pictured) and seeing the volcanic mountains surrounding Flagstaff allows us to understand the method by which God produced all other rocks.

In the first session of our trip on Sunday evening, before we departed, we pointed out the one basic assumption that underlies our entire trip. That assumption is that God is not a magician who does everything by slight of hand and magic. We see God’s engineering skills as He uses natural processes to produce things in the creation. The Bible tells us that “God planted a garden” (Genesis 2:8) not that He waved a magic wand and a garden appeared. When God created man’s body in Genesis 2:7, he “formed man of the dust of the earth.” The Hebrew word used to describe that process is yatshir which is a word denoting something an artist might do in creating a work of pottery from clay.

God did not “zap” the Grand Canyon into existence with all its many kinds of rocks and embedded fossils. Many religious people want to have God “speaking” these things into existence. The Bible indicates that God commanded the creation elements indicating that other agents were doing the actual work. In our twenty-first century mentality of rejecting scams and con-artists, it is important not to put God into the role of being a trickster. God did His creating process in such a way that we can discover the processes. That is the reason the Bible says we can “know God exists through the things He has made” (Romans 1:20). In Proverbs 8, wisdom personified speaks of God’s engineering skills.

We see the evidence of God’s engineering skills in the creation processes, and we read the Scriptures that tell what happened. Our approach to all of the evidence and the Scriptures is that they MUST agree. If the same God who gave us the Bible also did the creating, they cannot disagree. If there seems to be a conflict between the scientific evidence and what the Bible says, we either have bad science or bad theology or both. There has been plenty of both.

Tomorrow, we will continue to examine more of the things we saw of God’s engineering skills during our week in the canyonlands.

Canyonlands Educational Tour 2018

Canyonlands Educational Tour
One month ago, on Sunday, September 9, 2018, we began our thirty-sixth Canyonlands Educational Tour. Since 1968 we have been taking what I call field trips into the Grand Canyon and the areas that surround the Grand Canyon. That includes Bryce Canyon, Zion National Park, Canyonlands National District including Lake Powell, Meteor Crater, Painted Desert, Petrified Forest and the areas that surround all of those places.

My constant companion and technical expert has been Alan Doty from Sedona, Arizona. He holds advanced degrees in geology and has been a well-known figure in the area and an active Christian. Alan has made over 300 trips to the bottom of the Grand Canyon and was the first to climb Isis Temple. His knowledge of the area is second to none. Our trips into this area have included four boat trips on the Colorado River through the Grand Canyon, ten bus trips in which we spend a day at each of the sites of interest, and 16 hikes into points of interest in the canyonlands area. We have prepared field trip guides and have conducted studies and lectures on all of the trips.

Why do we do this? The Does God Exist? ministry is dedicated to providing evidence to convince thinking people that science is a friend of faith in God, and that science and the Bible do not conflict. As educators in the public schools, we have seen a great deal of bad science and bad theology combine to destroy the faith of many young people. There is no area where more bad science and bad theology have been promoted than in the canyonlands area.

Not understanding the evidence and not taking the Bible literally have led to a major source of conflict for many people. By taking the Bible literally, I mean looking at who wrote the passage, to whom they wrote it, why they wrote it, and how people of the time would have understood it. Having a week of concentrated study in one of the greatest natural science laboratories on Earth is a wonderful way to combat bad science and bad theology. It is also our hope that participants will go back home and use what they have learned in our seminars to build the faith of people in their home congregations. At the same time, we want to prepare them to combat the efforts of local skeptics to discredit the Bible and destroy faith in God.

Over the next few days, we want to give you a glimpse of what we did on this year’s Canyonlands Educational Tour.

NASA Turns 60

NASA Turns 60
In 1957 when I was 19 years old and a junior at Indiana University, the Soviet Union placed Sputnik, the first artificial satellite into orbit around the Earth. The following year the United States established the National Aeronautics and Space Administration with the goal of staking America’s claim to the cosmos. NASA turns 60 this year with an incredible record of accomplishment.

There have been 166 manned missions, 116 satellites which study the Earth, 70 missions to the moon and planets, 27 telescopes/observatories placed in space, and 17 satellites studying solar wind and interplanetary science. We now have robots making incredible discoveries at every turn, and plans are in the works for the first humans to land on another planet.

As a physics major and later as a physics teacher I have been enthralled with NASA’s accomplishments. I have had students who graduated from my high school and went on to have key roles in NASA. As those students come back and share their experiences and what they have discovered, I have been encouraged. I am excited by the fact that most of them see their discoveries, as I do, as a way of learning what God has done and understanding some of the methods He has used.

What an exciting time to be alive, and what a blessing it is to learn and grow in our faith and our knowledge! The more we know of the creation, the closer we get to the Creator. As NASA turns 60, I look forward to what lies ahead.

Fake Documentaries

Fake Documentaries
One of the frustrations of politics for us common folk is not knowing what is factual and what is fake. Any fact that a politician doesn’t want to hear can be labeled and discarded as “fake news.” The same problem exists on popular television in what we would call fake documentaries.

People seem to feel that if they see something on television called a documentary that it is true and has been verified by a reputable source. Religious groups, atheist groups, and food fad groups produce fake documentaries. They are also created by promoters of ESP, people who advocate alien visitations to Earth both now and in the past, and people who just want to make money with a fake documentary.

In the November issue of Astronomy magazine (page 64), Jeff Hester tells of being asked to comment on a bogus show about UFOs. The show was called a documentary and Hester, who is an astrophysicist, was interviewed as part of the program. The claims were totally false, and Hester said so in the interview and assumed the documentary would be scrapped.

The show was eventually broadcast as a documentary and given broad exposure. Hester called the producers and pointed out that he had shown that the story they were presenting was false. The producers admitted that they knew it was false. Then they stated something which Hester quoted in his column:

“Documentaries on stuff like this aren’t meant to educate people. They’re meant to sell soap. My job is to tell the intended audience exactly what it wants to hear. If people want to see miracles and space aliens, I show them miracles and space aliens. That way they tune in, watch to the end, leave happy, and buy the sponsors’ products.”

Remember that this was a television show called a documentary which many people will quote and believe. Yet the person who produced the fake documentary freely admits it was fake. Hester concludes “..they’re just plain old-fashioned carnival hucksters, picking the pockets of gullible people they play for rubes.”

We try very hard to quote scientific research from credible sources that can be verified. We also remind our readers that there are fake documentaries. We encourage you to think, and not believe something you see on television just because it is called a “documentary.”
