IN OPPOSITION OR
IN HARMONY?
“Religion and science are
opposed…but only in the same sense
as that in which my thumb and
forefinger are opposed- and between
the two, one can grasp everything.”
Sir William Bragg

“Who can learn anything new and
not find it a shock?” John Wheeler
It is helpful to regularly review even
our most fundamental
understandings in light of our most
recent discoveries.
Religion and Science:
Two Sides Of One Coin
Warm summer evenings in Greece in the 4th century B.C.
Democritus¹: 460-370 B.C. “Atomic system” wandering
lights in the night sky, (GK. “planetes”, “wanderers”).
Stationary grains of sand on the sea shore, (“atomos”,
“atoms” meaning “indivisible” or “unbreakable).
Aristotle: 384-322 B.C. The father of science. Knowing
the physical world inexorable leads to knowing the
existence of God & His qualities. (“physika”, “physics”, Gk.
“of nature”, “to bring forth”). Four elements, each with
their unique place & duty in the universe² Everything held
in it’s place, whether fixed or in motion, by eternal
natural laws, ordained by God.

DARK MATTER & ENERGY OR
SPIRITUAL MATTER & ENERGY?
• Whatever one calls it, we now know that @ 96% of
the “Stuff”, mass¹ in the universe is not visible to us.
We only see the gravitational effects of 23%.
• Whatever one calls it, we now know that 73% is
energy¹ in the universe that is not visible to us. We
know that it is there because at scales larger than
galaxies it overcomes Gravity².
• It really is meaningless to try to distinguish between
physical & spiritual matter & energy. It is a
distinction without a difference. This makes them
the same⁴. It does not make either of them unreal.

Religion and Science:
Two Sides Of One Coin
A warm summer evening in Woolsthorpe,
Lincolnshire, England, 1665. Isaac Newton Jr. (1642 1727, noticed an apple fall from a tree. At arms length
the apple appeared about as big as the moon appeared
that evening¹. Newton wondered why the moon was not
also falling². His discoveries changed the world in many
ways! His discovery of the Gravitational Force ended the
age of materialism³ & randomness. There was more than
“atoms and the void.” God did not need myriad angels to
push the moon & planets around⁴. Similar natural laws
might govern everything, including mankind⁵.
Religion and Science:
Two Sides Of One Coin
1. Peter Abelard: 1079-1142 Si et non. The nature of
Canon, (Authority¹) & it’s limits.
2. William of Occam²: 1285-1349 Occam's two edged
Razor, (scalpel) : Canon + reason.
3. Galileo: 1564-1642 & Isaac Newton : (1642 -1727)
Canon + reason + Observation & experimentation.
4. Robert Boyle, 1627-1691: Experimental
epistemology.
5. John Locke: 1632-1704: Philosophical epistemology.
6. Immanuel Kant: 1724-1804: Pure reason.

Religion and Science:
Two Sides Of One Coin
1. 57 centuries vs. 3 centuries.
2. Special & Natural revelation*.
3. An apparent conflict between them about
“what and how” is resolved by Newton,
(1642-1727) before it became popular:
• The Principia: The Mathematical Principles of
Natural Philosophy, 1687: Discovering God’s
Laws neither limits Him, nor eliminates Him,
It gives us deep, profound insight into Him.
10
Religion and Science:
Two Sides Of One Coin
The division between physical objects & laws
and spiritual objects & laws is a myth,
unrecognized by God, & great scientists
throughout history! Notice how often symbols
of spiritual laws, i.e. “π”,(the compass) “²“, ”³”,
“r²”, etc. appear alone, and in combination,
within so many, so called “physical” laws,
“discovered” millennia after the “spiritual”
symbols and laws had been revealed!
11
Epistemology
What is Knowable?
• There are eternal, universal, unchanging,
objective Truths¹, (Facts)! Everywhere! Always!
• Three very different types of Truth (Facts):
1. Definitional: Bachelors are single because that is
how we define the word. Everywhere! Always!
2. Logical/Mathematical: 2 + 2 = 4! Everywhere!
Always!
3. Empirical/Existential: Water is H² O¹ & it’s triple
point is 0° C at one atmosphere of pressure!
Everywhere! Always!
12
Things aren't always
what they seem:
1. What goes up must come down?
2. The Bigger they are, the harder & faster they
fall?
3. Does the sun rise in the East & set in the
West?
4. Is the chair you are sitting on solid & still?
5. Are you sitting on it at all?
6. Are your feet on the floor?
7. Is grass green?
But there are eternal, universal, unchanging,
objective Truths, (Facts)! Everywhere! Always!
13
Objective vs. subjective truth:
Thinking, speaking & writing on this subject is often
muddled and/or unreasonable. Truth is not subjective if it
meets the criteria of slide # 11. Subjective truth arguments
are often the victim of circular reasoning. If Relativists claim
that all truth is subjective and therefore personal & relative,
than this set, “all truth” includes their own claims of universal
“subjective relativity” and the rest of humanity has no reason
to give any heed to it. Their arguments concerning their
universe being without objective truth says nothing at all
about my universe! If they have an argument about my
universe, (or our universe) that argument would need to be
objectively true. If they can objectively know this,
(Inductively reasoning from their subjectivity, first to mine,
then to universal subjectivity) at least one truth is objectively
14
knowable and other truth may also be knowable.
Objective vs. subjective truth:
This would defeat their argument of universal subjectivity! This
assertion is also demonstrably false! (see slide # 11) What I
know & how sure I am that I know it is the object as well as the
subject of epistemology. It is silly nonsense to dismiss as
“subjective truth,” truth claims that one has not yet subjected to
rigorous tests of epistemological responsibility: “Your belief that
a man walked on the moon is only your subjective truth because
I don’t know that it’s true? The Nazi holocaust was immoral is
only your subjective truth because not everyone agrees?” The
whole purpose of epistemology is to rigorously test and
determine if one can know things and how certain one can be.
To dismiss something as “subjective truth” is to beg the
question and to deprive oneself of both the process & the
product of knowing! This is surely one of the defining qualities
15
and one of the noblest attributes of humanity!
Epistemology
How can I know Truth?
“Some ideas are so bad, they are not even wrong.”
Enrico Fermi. “It is better to be wrong, than to be
vague.” Freeman Dyson.
1. Sense & Non Sense¹: “Canoes, pancake covered dog
houses, and ice cream that doesn’t have legs.”
2. Dogmatism & sorcery: Repeating things
authoritatively doesn’t make them true.
3. Magical/wishful thinking¹: Much of atheism and
materialism is magical and\or wishful thinking.
4. If you call a dog’s tail his leg²… your thoughts and
your words are muddled and wrong.
• Falsifiability: The truth claims of Christianity ³are
completely factual, testable, provable (Falsifiable).
16
Epistemology
How can I know Truth?
1. Can I appeal to authority? Relying on a source
that we trust is the oldest and still by far the
most common way of knowing or making sure.
2. Can I reason through it? Does 2+2=4?
3. Can I observe it?
4. Can I experiment and test it? (Can I make
certain it is true?)
5. Can I “feel it” or “know it in my heart”?
6. Can God tell me it is true? (Can He make me
certain It is true?)

Epistemology
How certain can I be?
Degrees of Certainty: Faith, Emotion, & Evidence.
1. Probable cause¹:
2. Preponderance of the evidence²:
3. Clear & Convincing:
4. Beyond a Reasonable doubt:
5. Beyond any doubt:
6. No genuine question of fact exists (Judicial notice):
Faith is not believing something or trusting some authority
against common sense or without evidence or some degree
of certainty. Faith is sticking to your evidence based
convictions, even when you are emotionally tempted to19
Epistemology
How certain can I be?
“Any measurement that you make (decision
that you come to) without knowledge of its
uncertainty is completely meaningless.” “A
measurement that doesn’t also indicate its
degree of accuracy is meaningless.”
“Knowing degrees of accuracy is critical to
so many things in our lives.” Dr. Walter

Can I reason through it?
TRUTH
• Deductive Reasoning: Large to small: •
• Example: All Mammals are warm
blooded. Humans are warm blooded,
•
therefore humans are mammals.
• Inductive Reasoning: Small to large:
• Example: . Humans are warm blooded.
All Mammals are warm blooded,
•
therefore humans are mammals.
• Sequential Reasoning:
• Example: Smoke is seen after fire. I see
smoke, therefore there has been fire.
• If the premise is false, the sentence is
non-sense, even if the conclusion
happens to be true².
ERROR
Example: Many men are
selfish. Bill is a man,
therefore Bill is selfish.
Example: I knew a kind
Christian. Bill is a
Christian, therefore Bill is
kind.
Post Hoc Reasoning¹:
Example: I saw a black cat.
Something bad happened,
therefore seeing a black
cat is bad luck. I went
outside when it was cold. I
got sick, therefore being
outside in the cold causes
30
sickness.
STATISTICAL SIGNIFICENCE
• Small sample error: One type of error in
inductive reasoning: “Crocodile Dundee” TV
scene in NY motel: “Yep, that’s what I saw.”
• Galileo's experiments:
• The speed of light: How closely are we
looking?
• The spontaneous generation of flies: How
closely controlled is our experiment?
• Climate Change: How long will it take to
know?
31
Relying on authority
Almost everything we believe to be true, we
learned from some “Authority”. Generally we believe
because of authority. Most personal experience,
(observation, reasoning & experimentation) confirms
or disputes what we previously believed or doubted
because of authority. The Real question isn’t “Have we
faith in authority?” It is What or Which authority have
we faith in, how much faith do we have in it, and how
much additional research, reasoning and/or
experimentation will we do to test or verify what
“Authority” has said?
32
TOLSTOY & BACON
“I know that most men, including those at ease with
problems of the greatest complexity, can seldom accept
even the simplest and most obvious truth, if it be such
as would oblige them to admit the falsity of conclusions
which they have delighted in explaining to colleagues,
which they have proudly taught to others, and which
have been woven, thread by thread into the fabric of
our lives.” Tolstoy
“The human understanding when it has once adopted
an opinion…draws all things else to support and agree
with it. And though there be a greater number and
weight of instances to be found on the other side, yet
these it either neglects or despises.” Bacon
33
Types & Tokens
Type: A person or thing symbolizing or exemplifying the
ideal or defining characteristics of something.
Type: The ideal or defining characteristics of something.
Token: One specific example.
Token: One specific, distinct, physical, person or thing.
A chair is one type of furniture. A table is another type of
furniture. A stool is a type of chair. A recliner is another
type of chair; perhaps the perfect, ideal, or complete
“type” of chair.
The chair you are sitting in is a token chair. The chair next
to you may be a token of the exact same type.
34
INTRODUCTION
Measurement Standards & degrees of uncertainty:
VECTORS & SCALARS:
A scalar has only magnitude and no direction.
A vector is a physical quantity that requires the
specification of both direction and magnitude.
35
Ordinal Set Theory
Mohamed Ali and superlatives:
Someone is always “The Greatest”.
In any defined group or set, for every measureable quality,
one member of that group is “most” or “best”.
If qualities can be summed, someone is the overall “greatest.”
Of all beings currently conscious, one of them is the greatest,
(using the Laws, Constants, Forces, & Elements most effectively
to bless & serve others).
That being is God.
For Christians that living being is Jesus Christ!
Agnostics & Atheists have simply not been persuasively or
36
effectively introduced to Him, Yet!

ATOMIC THEORY
If one enlarged the baseball until it was about the
size of the earth, an average Carbon-12 atom in that
baseball would be about the size of a baseball. If
one enlarged the now baseball sized atom again,
until it was about 2 miles, (3.5km.) in diameter, the
nucleus would be the size of a golf ball in the center
and the electrons would be grains of sand, two miles
away with nothing, that we know of, except the
forces, in between.
ATOMS
• Ordinary matter is made of atoms which are
composed of electrons, protons, & neutrons.
• The nucleus contains between 99.945-99.975 of
the total mass of an atom.
• Atoms have an atomic number, Z = element =
protons in their nuclei.
• N = neutrons in their nuclei.
• Σ = The sum of N +Z = A = the mass number. There
are several mass numbers of each element. These
are called isotopes.
ATOMS
• Electrons almost balance out the protons to make
atoms electrically neutral in charge. (Electrons
appear to be without internal structure & are part
of the Lepton family within the particle zoo.)
• Most matter is slightly positively charged most of
the time. That is why we can sit on a chair, can’t
walk through walls & don’t fall through the floor &
the earth.
• Protons & neutrons each contain three quarks, (⁺⅔
+ ⁺⅔ + ⁻⅓ = 1).
• There are six kinds of quarks, two of which (up &
down) make protons & neutrons.

We do not live in an (exclusively) material world!
We live in a Universe, with Eternal Laws,
Constants, Elements, (materials) and Forces.
• They are the Typical God: Eternal, unchanging,
omniscient, omnipotent, & omnipresent!
41
There Are many Universal
Laws, (Equations)!
The Five Equations that changed the world are a few
examples:
1. Gravity F = G x M₁ X M₂/d². Newton.
2. The 2nd Law of Thermodynamics: (Entropy)
ΔS ˃ 0. Clausius or ΔS = ΔQ/t.
3. Hydrodynamics: Constant = P/ρ + gz + v²/2. Bernoulli*.
4. Electromagnetic induction¹: (EM)
ΔX E = -∂B/∂T. Faraday-Maxwell. F = K x q₁ x q₂/d².
Coulomb.
5. Matter is energy: 𝑬 = 𝑴𝑪². Einstein
42
There Are Universal
Constants!
• There are hundreds of precise Fundamental
Constants in our universe. They must be EXACT:
• Never more. Never less.
• No where more. No where less.
• Never different. No where different.
• “Who can learn anything new and not find it a
shock?” John Wheeler
• It is helpful to regularly review even our most
fundamental understandings in light of our most
recent discoveries.

• There are 92 natural elements, distinct
atoms, in our universe. They each have
their own distinct atomic number and their
own distinct atomic weight.
• Never more. Never less.
• No where more. No where less.
• Never different. No where different.
53
There Are Universal
Elements!
• Paley¹ observed that if one discovered a watch among
iron ore, correctly set & keeping proper time, one
would know that a watchmaker had created it. (1802)
• Now that we know how God made the elements, 90 of
92 forged in the furnace of giant stars, not only are the
“creations” “Paley’s Watch”, but the ingredients used to
build the “Watch” are also “Paley’s Watch”.
• To discover something brilliantly, even exquisitely
designed, creatively and skillfully constructed, currently
operating with minutely tuned precision, and think it
had no Creator, is as Schopenhauer observed, “Not
merely mistaken, but stupid.” (1860)

argument for God’s existence is even more plainly

There Are Universal
Forces!
The True meaning of Omnipotence: Beyond passive
Laws that cannot be broken¹, there are powerful Laws,
Forces, that literally, physically force their influence upon
us! This is A fundamental misunderstanding of
disobedience! We do not ever break God’s laws, we
sometimes break ourselves against them! “Obedience” is
from a Greek word, ”hpakono”² through Latin, (ob oedire
“toward + hearing”) meaning “to listen”.

4. STRONG: Einstein, Oppenheimer, et. al. : ¹₁H + ¹₁H →
²₁H + °₁e + v. ¹₁H + ²₁H → ³₂He + ϒ. (followed by either)
¹₁H + ³₂He → ⁴₂He + °₁e + v x C², or ³₂He + ³₂He → ⁴₂He
+ ¹₁H + ¹₁H x C².

Gravitational Force
F = G x M₁ X M₂ \d².
• God uses gravity to hold many things in the universe in their
exact proper places, in a very complex interdependent dance.
• Man uses gravity to hold satellites in orbit with great skill &
exact calculations for a few years. To believe God did not
place the earth and moon into a much more precise orbit for
billions of years: Now that is an act of Blind faith*!
• Where did Newton get this knowledge? According to his
testimony, The Christian God revealed this to him! And a great
deal more! Newton was perhaps the greatest scientist who
ever lived. His Christian devotion is second to none. His
discoveries changed the world. Shall we ignore other things
he learned, and how he learned them? Is it better to have one
article, or continuing access to the Internet?

G = 6.6725985 x 10¯¹¹m³kg¯¹s¯².
• Sometimes we rebel and disobey gravity, injuring or killing
ourselves and/or others.
• Sometimes our disobedience makes our burdens greater and
our lives harder.
• The ‘Thou Shalt not’s’ in scripture protect us from these
errors¹.
• The lever, pulley & Wheel-barrow are examples of simple
obedience to God’s law of gravity that makes our lives easier².
• Satellites are an example of a higher order of obedience to
gravity, making possible many ‘miracles’ that seem magical to
those who do not know these laws or refuse to obey them³.

LARGE NUMBERS
& DIVERSE SCALES
“We are each made up of between 10²⁸ and 10²⁹
atoms. This ‘human scale’ is, in a numerical sense,
poised midway between the masses of atoms and
stars. It would take roughly as many human bodies
to make up the mass of the Sun as there are atoms
in each of us. But our Sun is just an ordinary star in
the galaxy that contains a hundred billion stars
altogether. There are at least as many galaxies in our
Observable Universe as there are stars in a galaxy.
More than 10⁷⁸ atoms lie within range of our
telescope.” There are @ 3 * 10²⁷ stars.

LARGE NUMBERS
& DIVERSE SCALES
“Living organisms are configured into layer
upon layer of complex structure. Atoms are
assembled into complex molecules; these
react, via complex pathways in every cell, and
indirectly lead to the entire interconnected
structure that makes up a tree, an insect or a
human. We straddle the cosmos and the
microworld-intermediate in side between the
Sun, at a billion metres in diameter, and a
molecule at a billionth of a metre.

It is actually no coincidence that nature attains
its maximum complexity on this intermediate
scale: Anything larger, if it were a habitable
planet, would be vulnerable to breakage or
crushing by gravity.”
“ We are vulnerable to viruses a millionth of a
metre in length, and the minute DNA doublehelix molecule encodes our total genetic
heritage. And it‘s just as obvious that we

“ A bit of gossip starting in Washington reaches New
York very quickly, even though not a single individual
who takes part in spreading it travels between these
two cities. There are two quite different motions
involved, that of the rumor, Washington to New York,
and that of the persons who spread the rumor. The
wind, passing over a field of grain, sets up a wave
which spread out across the whole field. Here again
we must distinguish between the motion of the wave
and the motion of the separate plants, which undergo
only small oscillations…

Φ OF WAVES I.
• Forced vibrations & resonance: Crystal shattered
by a human voice: In a tube open at both ends he
natural frequencies of vibration form a series in
which all harmonics are present and are equal to

Φ OF WAVES I.
• Vibrations of continuous systems:
If two or more waves are moving through a
medium the resultant wave equals the sum of
the displacements of the waves point by point.
Φ OF SOUND WAVES.
The limits of hearing are dependent on the
frequency of the tone & usually vary between 50Hz12,000Hz with 3300Hz being easiest to hear.
Φ OF SOUND WAVES.
• Ultrasound & other digital sound technologies:
The process of converting mechanical energy (sound)
into electrical energy & vice versa is called the
Piezoelectric effect.
