Memory and Old Age
Next July I will join the Octogenarian fraternity. I don’t
like the idea, but it is certainly better than the alternative. Mentally, I
feel like I am still around 50 or so, but my body keeps letting me know the
truth! I must face the fact that I simply can’t do the things I once performed
with ease. For example, I pick up a tree branch and wonder how I ever picked up
and walked with a four foot, twelve inch diameter log, then threw it onto the
back of a truck. Does anyone identify?
Memory is another problem. Around ten years ago my doctor
asked me how my memory was doing. I said I was not happy with my increasing
inability to remember things. He responded that, in that case, everything was
fine. He went on to say that he had never met a person with Alzheimer’s that
had any problem at all with memory (according to the patient, of course!).
Actually, my memory is all still there, but it certainly often takes time to
recall seldom used items. Names are a particular problem. It will sometimes be
a day later before the name I am after suddenly pops up in my awareness. Fortunately, my wife is good with names, so she
can usually help out with an immediate need. Rarely used words are also a
problem.
As I talk to others, I find that I am not alone. My problems
seem to be a function of aging – not experienced by all, but not avoided by
many. As I have mulled over the problem, I have finally understood the problem.
Computers are often compared to human brains, so let’s reverse the comparison.
A computer contains two types of memory: random access memory (RAM) and read
only memory (ROM). Things used regularly are held in RAM, and those things
seldom used are normally placed in ROM. The primary reason your computer is
sometimes quick and sometimes takes time to respond can be explained by where
the memory you are accessing is stored. Those things stored in ROM usually take
longer to access and bring forward.
What about the brain? It seems to also have a section for
RAM and a section devoted to ROM. As you age, RAM gets filled up. Therefore, if
something needs to be remembered a bit of memory needs to be freed, so
something seldom used is transferred to ROM, becoming harder and slower to
access. Those items transferred to ROM are most frequently names and words
seldom used in day to day conversation. Not only do they become harder to
access, but the less they are used the deeper they move into the ROM memory
banks and the longer it takes to access them.
So, there you have it. That is why you have (or will have) more
and more problems with remembering things as you age. That is my explanation and
I stick with it!

INTERNATIONAL YEAR OF SOILS
How many of my readers have heard of the International Year of Soils? The year will be ending in 28 days. Why an International Year of Soils? Without soil much of the world would be starving. Yes, we can grow plants in water, but not enough to feed the world. Most plants get their food, water, and support from soil. Most food is grown in soil. Trees grow in soil. Think about where we would be without soil. What would we do for protein? We can get protein from plants in correct form and combination, but most protein comes from animals . . . that live on plants. What would we do for shelter? Trees grow in and on soil, so without soil there would be little wood for construction. What would we do for heat and energy? Coal, oil and gas all originate through plant growth. Wind and Solar energy you say? How would you build the equipment to collect the wind and solar energy? Regardless whether the equipment is made of metal, glass, plastic, or something else, energy is required for production, and that energy originates in plants and, ultimately, the soil. That is the reason for an International Year of Soils!
Each month of 2015 had a theme addressing one aspect of our dependence on soil. Here are the monthly themes and a website where you can access related information. I encourage you to explore these websites if you have not already done so.

HOW DID THE BIG BANG HAPPEN???
Have you ever driven in a “pea soup” fog? I have . . .
twice. You creep along, and as one center line dash disappears from sight the
next one emerges from the fog. Even fog lights are useless. They can’t
penetrate the fog. You may be on a mountain road, as in one of my experiences.
You are tense, fearing you might miss that next curve, or it might be sharper
than expected. Science can be like that. Your mind creeps along from one idea
to another, trying to make sense of the whole. You may finally have a “eureka
moment” and the fog disappears, but you are still not really sure how you got
there.
Back to that mountain road, a car suddenly appeared behind
me, passed me, and disappeared into the fog. It was as if I were parked. I
proceeded down the mountain, expecting to find the car crushed against a tree
or a broken guard rail where it had gone over a cliff. There was nothing. The
diver had obviously driven the road many times and knew every curve. Scientifically,
Stephen Hawking is like that driver. His “fog” is his non-functioning muscles.
He has nothing to do but think, and he has become very proficient at thinking.
His brain has become comparable to the muscles of a world champion body
builder.
Among many problems, Dr. Hawking has directed his brain into
the “curves” of the Big Bang theory. Carefully
considering every “curve,” he concluded that this occurred into nothingness –
no time, no space, no mass – simply nothing. It was not even comparable to a
vacuum, because a vacuum implies space! In reality, this is basically in
agreement with the Judeo-Christian explanation of our beginnings. But how can
this be? Logic says it shouldn’t happen. Thermodynamics calculations say it can’t happen. Yet it did. Something had
to be present, and it had to be in a unique form never attained since.
My brain power does not approach that of even one a small lobe
of Dr. Hawking’s, but allow me to at least consider the possible conditions
leading to the Big Bang.
First, there is a thermodynamic temperature scale, only used
by scientists, called the Kelvin (K) scale. Zero Kelvin is considered “absolute
zero,” at point at which everything should be frozen; 0o K = −273.15°C
= −459.67°F. Scientists have been able to cool systems close to absolute zero,
but it is not even theoretically possible to reach the zero point. Were this
possible, a system at absolute zero would still have mass. Therefore, whatever the
Big Bang was, it probably occurred within a system at a temperature even below the
thermodynamic absolute zero.
Second, in another blog I pointed to Einstein's equation, mass equals energy divided by the speed of light squared (M=E/C2, or he
stated it as E=MC2). In other
words, all mass is nothing more and nothing less than organized energy. The
atom bomb and the subsequent hydrogen bomb supported this theory as being true.
Modern research is also supporting the theory. Going back to conditions prior
to the Big Bang, if there was no space and no mass, whatever initiated the
university had to be energy only. Furthermore, all of the energy had to be
potential energy only. The presence of kinetic energy would mean something was
moving, which would imply the presence of space.
If nothing was moving, then even electrons and their
components could not be moving. For that matter, electrons or their components could not have even existed because, no matter how small, they would
have occupied space – which was non-existent. This leaves with one and only one
possibility: immediately prior to the Big Bang event there could be nothing
present but some potential energy. How can this be?
Given that we now have some potential energy floating in
nothingness, expansion into a universe means that some kind of spark had to cause a
small packet of potential energy to transfer into kinetic energy. This packet
would have nudged another small packet of potential energy, and a minute amount
of heat would have resulted. Suddenly we have a chain reaction and the
potential energy transfers to kinetic energy and space is created. The packets
of energy organize into hydrogen atoms, and off we go!
Assuming this is what happened, we still have unanswered
questions. Where did the original energy come from? Can energy exist separate from mass? Where did the initial spark
come from? Can we ever know? Some physicists hypothesize prior universes and that ours somehow originated from them. That just begs the question, because we would then have to ask how any "parent" universe(s)
originated. Jews and Christians have the answer: God did it. But that, in turn, raises
another question. Where did God come from? All this is meaningless, because the origin questions are unanswerable.
OK, theoretical physicists, where am I wrong? Or am I just
repeating conclusions that you drew long ago?

MATTER/DARK MATTER – DOES IT MATTER?
What is
matter anyway? Einstein theorized that all matter is simply constructed from
energy. Does that make sense to you? We think of objects in the terms of the
whole. Certainly, we understand that a car, for example, is constructed from
many parts, but where is the energy? If two cars collide, pieces of the car are
scattered in the area. There is also sound and a certain amount of light and heat
associated with the collision. Sound is really energy traveling through the
air, and if loud enough it can cause damage. We usually can understand
that heat is energy; who has not been cold in a very overcast day, only to
be warmed if the sun suddenly breaks through the clouds and sunlight hits us.
So, light, too, is a form of energy traveling through the air.
Back to the
wrecked car that is now in pieces. We pick up a piece of metal, which is now
simply a mass of iron, or maybe aluminum, with, perhaps, a few other metal s
mixed in. We pick up a piece of glass, which is silicon. We pick up a piece of
plastic, and know it is made of carbon and oxygen, maybe with a few other
constituents. All of these elements are much too small to see individuals, but
working together they form a solid piece called matter.
Now we take
our car pieces to a laboratory. It takes some pretty elaborate equipment, but
we separated and look at a few element atoms. We discover that each atom
consists of a positively charged nucleus and surrounding negatively charged electrons.
We also discover that the nucleus is actually made up of positively charged
electrons. The only real difference between our iron, aluminum, silica, carbon,
and oxygen atoms is the number of positive electrons in the nucleus!
The number
of laboratories in the world that can go farther begins to decrease, but we can
actually continue breaking down the wrecked car pieces. We find, for example, that the oxygen
nucleus is about five femtometers in diameter. I don’t know about you, but I
can’t think that small! I can think down to one millimeter, because a ruler is
divided to that extent. However, there are 1 billion femtometers in one
millimeter! (I can’t think that large either!) The electrons are only about one
hundredth of the size of the nucleus. Yet, now equipment exists to study the
properties of electrons, and it turns out they are made up of even smaller
particles. So far as I know, there is only one lab in the world that can study
these smaller particles by causing them to collide at near the speed of light.
When this happens, they are, basically, dissipated into energy!
Conclusion:
Einstein was correct and matter is nothing more and nothing less than organized
energy!
What about the so-called dark matter? Astrophysical
measurements and calculations during recent years indicate there is something
in the universe that can’t be seen or measured in any way. It has been labeled
“dark matter,” but what is it? How does it differ from solid matter?
Matter can be seen, felt, and measured, but is it really
solid? What is “solid” matter, anyway?
It has been concluded that matter is nothing but energy, but matter sure
feels solid! It feels solid simply because the energy is organized, and the
organization is controlled by a balance between attractive and repulsive
forces. For example, gravity is simply a convenient way to express the
attractive forces between bodies. We stay on the surface as a result of
repulsive forces between bundles of energy. If this balance were to disappear
we would either migrate to the center of earth or fly off into space. In either
case we would likely disintegrate into our component energy.
Returning to dark
matter, apparently, these attractive and repulsive forces do not exist. As a
result, there is nothing to reflect light and therefore nothing to see, either
visibly or with any instrument currently available. Were we to touch this dark
matter, our hand would pass through it and we would never know it was there.
Likewise, it could be constantly passing through us unknown. We do know there
are cosmic particles that pass right through the earth unchanged without having
any effect on it.
One can only conclude that dark matter may be no more and no
less than a collection of unorganized energy. It could be left-over energy from
the beginning, or it might be the result of some matter having been annihilated.
Thus, whatever its source and make-up, whether dark matter
matters depends on its role in the universe (and, of course, whether funding
agencies feel it important enough to provide scientists with the funds
necessary for its study).
The greatest questions are: 1. What is the source of all
this energy? 2. How would it have
appeared suddenly into nothingness? And, greatest of all, 3. How would this
energy have spontaneously become organized into our universe’s many forms of
matter?

WAS IT EVOLUTION?
(Excerpted from "Scripture versus Science: Reconciling God's Ancient Wisdom With a Modern world View")
Many of the
world’s biologists claim that the fact of evolution is settled. They hold firmly to
evolution being a provable fact. In another blog I have pointed out that there is no physical evidence of
an evolutionary process, let alone a testable hypothesis of how it happened.
Their conclusion is based primarily on two general observations. Similarities
between divergent species have long been considered an indication of a
relationship of some kind. Now that the human and many animal genomes have been
mapped, the striking similarities between the DNA of all animals is taken as
proof of evolution. The high correlation between the DNA of humans and primates
in particular has been taken as evidence of common ancestry. Let us consider
the DNA observations.
Jeremiah it told to "go to the potter's House." (Jeremiah 18:2), so let's do likewise. What do we see there? A
potter throws an appropriate quantity of clay onto a spinning disk and
begins to shape it into the desired form. As skilled fingers work, an urn, for
example, begins to take shape. If that isn't working right the potter may decide to make a cup instead. The process
remains exactly the same, but the slight changes create a different product. Only the quantity of clay used and
the finishing touches differ.
The finishing
touches are what make each product unique. Each piece of pottery is one of many, perhaps a group of containers or perhaps a group of gallon jugs. In all pieces the production process is identical. Whether a part of a generic group or a specific use group, however, the potter imparts a unique personality onto the piece. Every living organism, whether under the classification of the animal kingdom or Homo sapians has some degree of similarity. Likewise, every living organism is unique in some small detail. Humans are all basically of the same form, and at a larger scale we are even similar to all mammals. Two people may look similar, but there is always some difference
between them. Every individual on the earth is unique in some way.
As biological
scientists have unraveled the complexity of DNA, they have discovered that all
animals have a similar pattern, and human DNA differs only slightly from that
of primates. This has been used to “prove” that humans did not arise through intelligent design, but evolved from an ancestor common to the primates.
However, this proves nothing other than a person’s inability to consider the
option of intelligent design. If one applies a bit of logic, would it not make
sense to find that all animals have similar DNA? Why would a designer alter the
basic structure of a successful design? A potter does not redesign the entire
process when embarking on production of a new piece. Does a builder redesign
the basic structure for every new construction project? Would a scientist
design a new protocol for every potential research project? Of course not. No
matter how simple or complex a project may be, the starting point is the same
for all similar endeavors. Only the details are altered to fit the requirements
of the project at hand.
Despite the
claims of biological scientists, similarities in animal genomes do not prove
they were created in an evolutionary process. In fact, sections of the genome that
have been considered “junk DNA” have recently been found to be the instructions
for creating a unique individual, so our DNA is not so similar to primates as
scientists had previously assumed. It must be recognized that whether humans were formed through intelligent design via DNA manipulation
(supposedly evolution) or by some kind of spontaneous creation process,
similarities in the gene sequence would be logically expected.
As pointed out in another blog, a major
problem with the traditional evolution theory is that it requires a series of
mutations to explain the transformation of one species into another.
Theoretically, slow change is a possibility, but since any hypothesis of the
formation process is based on observations, we must consider the observation
that only very rarely do mutations result in a viable organisms. Mutations are
almost always fatal to the offspring. Any evolutionary
process should be supported by finding organisms with properties intermediate
between the assumed parent and offspring. This criticism is answered by
assuming that changes occurred rapidly, so few intermediate species existed
from which fossils would be formed. The problem here is that a series of nonfatal
mutations would have been required, and if single nonfatal mutations are rare,
a series of such mutations over a short period of time would be extremely
improbable, unless controlled through intelligent design.
To compound
the problem at hand, and to enable the reproduction system, similar evolution
had to happen simultaneously to a woman and a man; otherwise their children
would be some kind of hybrid and could not create human offspring that were duplicates
of themselves. On the other hand, if the genes were carefully adjusted to
form a human, would it not be a simple matter of changing the
Y-DNA that defines a man into the mitochondrial DNA that defines a woman?
Within either the plant or
animal kingdom, one would expect DNA commonality to increase with the degree to
which two organisms share similarities. It
should be expected that humans share some DNA characteristics with cows or elephants.This similarity should
not be used as proof of a common ancestor. It can be considered as
evidence of intelligent design. In reality, evolutionary changes by natural alterations of DNA to form
humans are infinitely improbable. When biological scientists insist that all
life forms are the result of an evolutionary process, they are actually
admitting that there is an intelligent designer in charge of things.
