WHAT ARE
“... OVERSIGHTS”?

HUMOROUS... INSIGHTS
Into
FUNDAMENTAL “...
OVERSIGHTS”Let us start with some humorous insights, and some serious ones.
When thinking of serious... oversights in science and
mathematics there is a chess aphorism that comes to mind:
-
When
a beginner gives away his queen,
it’s a blunder.
-
When a grandmaster gives away his queen,
it’s an... oversight.
Humor has found use since time immemorial as a mnemonic and teaching device, and
perhaps even more as comic relief. Shakespeare is a constant reminder of how important
that last is. Humor has been found by the wise to be not only helpful, but
essential to aiding the process(es) of learning, growth and
evolution toward wisdom, and in science and mathematics there are so many... oversights and of such a serious nature that comic
relief will eventually be welcomed wholeheartedly. (Here, the ellipsis... has been added to the old aphorism to further
all those.)
Perhaps humor will help ease the current situation, since
scientists and mathematicians generally do not — or would not, if questioned —
credit that science and especially mathematics could be guilty of any truly
serious or prolonged... oversights. But we have
Newton’s Great... Oversight as a clear counter-example in the
“king” of sciences, physics, that for over 300
years scientists have held that lighter and heavier bodies — a la Galileo — fall
at the same rate, when Newton’s own theory clearly
predicts that they will fall at different rates (except at
Lagrangian points L4
or L5).
The falling rate difference is crucial
from the standpoint of the psychology and philosophy of science, but not from
the standpoint of changing theory itself.
Newton’s Great... Oversight should
provoke embarrassment, much soul and theory searching (looking for other...
oversights), and renewed appreciation of science itself, but no upheaval in physics theory that will
e.g. promote migration toward Einstein’s relativity.
But we have other clear
counter-examples — much more devastating ones — not only in
“the
queen of sciences”, mathematics, but in its
flagship,
Set Theory. We can peer into the psychology of mathematicians concerning one of the more important of these
Fundamental... Oversights (which see in
Mathematics; reiterates for overall emphasis but expands on some
of what follows in this section):
Relatedly, and more seriously:
But mathematicians do
systematically reject such derivations, such as subtracting 1 element at a time
from the set of all natural numbers Á 4 {1,2,3...}.
The reason this otherwise standard derivation from the standard axioms and rules
of inference is rejected is that the sets cardinality remains a0
as each element is removed, even when all the elements have been subtracted out
and all that remains is the empty set!

PERENNIAL... OVERSIGHTS
IN SCIENCE and MATHEMATICS
It is more than intriguing psychologically
that Sir Isaac Newton, of all people, not to mention every scientist
since, overlooked that Galileo’s lighter
and heavier bodies generally fall at different rates (with the fascinating
exception of... well, you can read about it in
Newton’s Great... Oversight); it is even somewhat terrifying.
Newton’s... oversight was certainly
important enough scientifically in its day. Newton and his contemporaries
should have applied the new “law” of gravity to the
same-falling-rate hypothesis of Galileo. It is very important and somewhat
terrifying that they did not do so. And, extremely important and even more
terrifying, this oversight has continued for over 300 years, even into the
beginning of the 21st Century.
But the far more grave source of terror that we all
should feel is... anger. Seriously, in just the last few years (here
nameless) leading scientists literally have become overtly angry
at the questioning of established scientific belief, especially such a
basic belief, when the case for the difference in falling rates was first
presented to them. This anger is far more terrifying than even great
oversights. Only grudgingly did some of them later permit the
equations and analyses to be presented and studied. Only grudgingly did
they then finally admit that the falling rate difference did actually
exist, but they generally disparaged the result saying things like “it’s
too small to be important.” When it was pointed out that physics
is proud of detecting the “infinitesimal” advance in the perihelion
of the orbit of Mercury... all further conversation came to an abrupt halt.
It is extremely unlikely that anyone will say that
the discovery of this... oversight of Newton — and unfortunately also of
every scientist since Newton to the beginning of the 21st
Century — terrifying though it is, is the apocalypse. The “infinitesimal”
advance in the perihelion of the orbit of Mercury could spell the
difference between Newton and Einstein, but the falling-rate-difference
question is just... Newton. It is fascinating from a historical perspective,
essential from a psychology of science and scientists perspective (see
below). It may be hoped — greatly — that it will help science give up
its unspoken intent to be the new one-true-religion (by one or another
variant of “killing the father and marrying the mother”), but it will provoke no revolution or shift of standard
scientific paradigm, in the sense of Thomas Kuhn.
Actually, that last needs qualification. Realizing
that lighter and heavier bodies fall at different rates will not really
improve e.g. rocket science. The falling rate differences are not critical
there, and are largely taken into account implicitly in the equations and
calculations that the computers carry out. We already knew by way of
Lagrange about Trojan asteroids, and about the possibility of putting
space stations at Trojan points. Astronomy will be affected rather more,
because there is a good chance that this result will yield inspiration to
reexamine the Lagrangian concept of Trojan bodies and their stability. New
possibilities will be looked at and for, such as ternary star systems,
currently thought to be unstable per Lagrange’s analysis. (See also
Figure 6a and
Figure 6b.) But, still, this does not constitute a “standard” paradigm
shift (if there is such a thing). The real paradigm shift — a true
apocalypse for some — will be a “meta-paradigm” shift, a conjoining of the
“science
wars” with “scientific
revolution”.
The “science wars” do not currently take science to
task for failing on its own terms. But, here, we will take a quick look at
the systemic nature of error and failure in science.

5.2 Approximation,
Extrapolation, and Error in Science
If the angular deviation of 2 straight lines from
parallel is non-zero but very small, few scientists will say that they
will not diverge eventually, if — and this is essential — if
the problem is stated in these terms. If we have an electronic device, few
scientists will say that it will operate correctly under all
conditions, again, if the problem is stated in these terms.
It must be emphasized that:
-
Just
because we can’t pragmatically measure a deviation within a limited
experimental context does not mean that outside of that context the
deviation will not become very great, even if it remains pragmatically
unmeasurable because it is outside of the
experimental context. Science produces beautiful flowers, but all
too often they are hot-house flowers.
When the position is put forward that lighter and
heavier bodies must interact gravitationally, and that there is an
asymmetry that means that the falling rates might in fact not be precisely
equal, many scientists respond that the rate difference is “so small...”,
some even that it is “so small it doesn’t really make any
difference”. This is not the most “scientific” attitude one can imagine.
Science is supposed to be interested in such small quantities if in
fact they are real, as the falling rate difference is. Scientists neglect
that when this rate difference is given enough time we can actually
begin to measure it, or at least notice its effects. Science should also
be interested in small differences even — especially — if they are
methodological artifacts; these, too, need to be studied and accounted
for.
We have just seen that standard Newtonian gravity
(the theory) is enough to at least derive equations that show that,
according to that same theory, the falling rate difference is — generally,
but not always — not zero. In conjunction, the astronomically known
existence of Trojan asteroids is visible, scientific proof that the
falling rate difference is in fact — generally — not zero. By
Newton’s theory of gravity:
-
If Galileo had held a 1 kg mass in one hand and a 2 kg in the other, 1
meter apart, and dropped them from the Tower of Pisa, at the instant of
release the lighter body and the Earth would have accelerated together
faster by approximately m/sec2
(ignoring, of course, all the usual: “gravitational anomalies”, wind,
buoyancy, electro-magnetic effects, etc.)
When such bodies have an
extended period of time to fall, as they do in orbit, the difference shows
up; the bodies behave as though the approximation of “fall at the same
rate” were incorrect, which it is if extrapolated sufficiently
far.
Approximation is a necessary convenience to science,
but scientists — with disappointing frequency — confuse their scientific
approximations with “Laws of Science”, which by definition do not allow
for any exceptions. They also confuse their “Laws of Science” with “laws
of Nature”.
E.g. we may have a
scientific inverse square force law, but this does not mean that all
forces in Nature are inverse square, or even that gravity is always
inverse square. Whether or not the “Laws of Science” are considered
“universal”, approximations — by definition — only hold in limited
contexts. The limits of these contexts are all too often ignored by
scientists.
When dropping “higher order terms” from a Taylor
series in a paper, for example, scientists rarely — or perhaps never —
give any indication that they have studied the limits or thresholds beyond
which those dropped terms would become large enough to be pragmatically
interesting. That they might remain a very small percentage of order terms
is not the essential issue. That the perihelion of the orbit of Mercury advances
even if “infinitesimally”, that the continents and asteroids drift
slooowly so that eventually our maps, predictions, and other
extrapolations are “wrong”, these are essential issues of
science, ones that are all too often ignored. The case of the difference
in falling rates of lighter and heavier bodies and their relation to
Trojan/Lagrangian points is an example of this.
Approximations are inextricably linked with abstract
reasoning, and abstract reasoning is the sword that science lives by... and
perishes by. Eventually we must realize that abstraction — by definition,
by its own Nature — is only capable of reasoning about an
infinitesimal part of the infinity of reality. It is a perennial error and
failing of science that we do not universally recognize and realize this.
Ignored is the warning of, of all people, Aristotle.
He warned that for logic to be and remain valid, every entity reasoned
about by that logic must be and remain identically equal to itself,
sometimes rendered as: A ≡ A. (He probably... overlooked... that this
requirement also extends to what we today term logical operators, but,
what the heck.) Since science and applied logic/applied mathematics are both/all in the
position that an abstraction can never be the thing from which the
abstraction was... abstracted, both/all are essentially invalid. They are also
both/all formally invalid, since A 4 A is a formal requirement of the
foundational logic of both mathematics and science, thanks to, of all
people, Aristotle.
-
Science can never truly be essentially —
or even formally —
valid on its own
terms, since the map of abstraction —
along with its abstract reasoning — can never really be the
territory of reality, can never really be more than infinitesimally
analogous to the territory, can never even map more than an infinitesimal
portion of the territory of reality, or even of its Nature, who thankfully
will keep on doing as She darn well pleases.

5.3 Newton’s... Oversight:
How?! Why?!
How could such a simple, obvious result — the
non-zero falling rate difference of lighter and heavier bodies and its
essential relation to Trojan points — be overlooked by “the genius who
discovered gravity”? The answer most likely lies in the character of the
Renaissance which was flowering during Newton’s life. We will forgo
descriptions of Newton’s genius and character, and of his role in this
rebirth, to focus on what was happening spiritually and intellectually in
his day.
Europe was beginning to throw off the suffocating
rule and stultifying authority and power of religion as it had come to be
practiced in the western world. Galileo had actually been in peril of his
life from the Inquisition, and many others had lost their lives — and
souls — to it. Aristotle, ironically a pagan Greek, and his teachings had
come to solidly represent, and underpin, this ostensibly religious rule,
this ostensibly spiritual authority and power.
The world was not then known for great wisdom, nor is it today. Because
Aristotle and his science represented the power that many were liberating
themselves from, including the budding European neo-intellectual and
neo-scientific communities, they found it “necessary” to find fault with
him, to dismiss him, even to depose him and his teachings. The work of
Galileo concerning falling bodies flew in the face of some of Aristotle’s
teachings, overthrew them, in fact, helping to hasten the waning of the
rule and of the authority and power of the church. It was far too soon to
think of questioning this new Golden Calf, Galileo and his new science,
which had helped drive out that Sacred Cow, or rather Sacred Bull,
Aristotle and his now old science. If Newton or his contemporaries had
questioned Galileo, even on this one point, even with overpowering
equations, to these newly self-established renaissance renegades,
themselves among them, it would have been tantamount to turning traitor to
their newfound salvation, traitor to their divinely inspired but still
importantly self-achieved liberation from ignorance and error, traitor to
this new life that was beginning to form in the world, life that they too
were conceiving and giving birth to, and that they too were, themselves.
There is still the question of why no scientists since Newton have
questioned the no-falling-rate-difference hypothesis of Galileo. Here we
will merely note that, if by the time of Newton Galileo had become a
demi-god, Newton himself — even today “generally recognized as the
greatest scientist who ever lived” — soon became all but God Himself,
almost within his lifetime.
If “He” didn’t question Galileo...

5.4 Questioning
Scientific Dogma
The importance of Newton’s... oversight, great or
not, can be judged somewhat by the
response of some (luckily not all) leading scientists to this formal
falsification of Galileo’s fundamental result: anger. Some scientists’ first
reaction is just that, overt anger, anger that science is being questioned, especially such accepted and fundamental results. One, at first
quite angry (“you shouldn’t...”), later admitted, after it
was insisted that going over the equations was in order, that there was indeed a
difference in the falling rates, but he dismissed it contemptuously as
“too
small to be important”. When it
was pointed out that the advance in the perihelion of the orbit of Mercury was
also very small, but was considered scientifically important none-the-less...
end of communication.
Another reaction was that of a science teacher whose students had shown her
the equations that they found of the PAIAS web site. We exchanged several
e-mails discussing the falling rate difference, and she admitted that the
falling rate difference seemed to be scientifically correct. But she finally pleaded:
“but is it all right if I tell my students that lighter and heavier bodies
do fall at the same rate?” When I reiterated that although they fall at
different rates, they do fall at approximately the same rate
for our usual purposes here on Earth, that satisfied her enough that our
correspondence ended.
These sorts of reactions should give us all pause
—
scientists and non-scientists alike. We are made aware, perhaps yet again, of the
stultifying effect of insistence on not truly questioning beliefs,
scientific or otherwise, even of implicit insistence. Science — like
religion — has accepted too much on “faith”. By the way, the original
(Biblical) meaning of “faith” in religion was not what it is today; it was
never any kind of willful ignorance (“we won’t look through your
telescope, because we have... faith”). It was rather a “let them who have
eyes see” kind of thing, or “you will perceive well the truth of reality,
and the truth will set you free”, from which we have sadly departed.
The very real falling rate difference was readily
accessible to Newton’s contemporaries through his theory of gravity (at
least post 1687), not to mention Newton himself, and it is incredible that
not only did they all miss it, but every astronomer and physicist since
has missed it, as well. Perhaps we should note again that the temper of
Newton’s times was one which was still not intellectually free of the
repressive affects of Aristotle’s... eccentricities, at least not free of
the uses to which they were put by those in power. Even after Copernicus
these remained quite powerful, even as they slowly waned. Today...
Guilt — or innocence — by association is a popular
and deadly fallacy. There was a (subliminally?) felt need to reject all
of Aristotle, even when he may have been right, since he was both a symbol
of the earthly and spiritual rule, authority and power of e.g. the church,
and a heavy club to beat down “heresies” that didn’t want to submit to
that rule, authority and power. The struggle was very much one of the
young Turks of scientific Theory
versus the old Greeks of religious
Theology. We can note with serious irony that
Theory and
Theology are actually
spelled the same, and the “Theo”
in each is the Greek word for “God”. And both of these tend to lead
to internecine — and even intranecine — warfare. The War of the Roses may
be over, but this “War of
the Theoses” continues even
today. A Sacred Cow may sometimes be attacked, but only if it is on
the other side of the fence. Galileo was on Newton’s side — and
today’s modern science’s side — of the fence, and therefore to be
“protected” from questioning, to be protected from “when wrong to be put
right.”
We are currently in need of a good dose of:
- “... when
wrong, to be put right.”

5.5 Our Aristotles, Our
Galileos
Galileo is hard to fault since he had no real chance
of measuring a falling rate difference of m/sec2
from the top of the Tower of Pisa (or rolling balls down a inclined
plane), and since he as yet had no theory from
which to derive it. Newton, however... and every physicist and astronomer
since, at least to the end of the 20th Century... Well, because
science is really still in its infancy, or more correctly, still being
conceived, perhaps we should continue to grace the situation with the
term... “oversight”. Blunder sounds “so... harsh”. If there are any
“scientists”, however, who would dare to maintain anything like “the
difference is so small, it’s scientifically negligible!”, we could
negligibly quote Galileo:
Relatedly, Aristotle has historically come through
this falling rate difference contretemps not all that well. His falling
rate thesis... well... it is mainly humorous to point out that he was 2/3
right. Perhaps we should allow that Aristotle, too, did not blunder, that
he, too... “oversaw”. And when we stop to think that we are still
teaching in our schools a 300+ year old... oversight, it is good to remember
that, of all people, Aristotle also said:
Perhaps Aristotle doesn’t
come out looking so bad. After all, we really can’t afford to go on
teaching science’s... oversights, nor can we afford to go on teaching our
future scientists to be angry when people point out and question... The
Emperors’ New Fall Line. And he was 2/3 right!
Here at the beginning of the new millennium, as we
try to put it right, let us hope that science will soon give up its
tacitly-implicitly promoted position of “all-but-omniscience” and
“all-but-infallibility” (both in the “objective” “practical” sense, e.g.
one that “justifies” “ordering” people’s lives), and its more explicitly
public stance of science-versus-the-subjective-world that can be
poetically rendered as:
Questioning Sacred Cows is still considered heresy,
even in today’s science, so we can guess how the scientists of Newton’s
time felt, both as heretics themselves, and as a new establishment. But
the Inquisition won to this extent, that those who later came to question
the new scientific dogma did so in imposed silence, and all too often
still do.

5.6
“Science Wars” and “Ablative Shielding”
(and Science’s Implicit Infallibility)
In the current “science wars”, the critics of science
tend to recount the philosophical, social-sociological, ethical, and even
political failings of science, all rejected by science as unscientific
bases for criticism (of science, at any rate). Scientists, in turn, tend
to recount the “scientific” failings of science’s critics (academics in
the “soft” social sciences and cultural studies, feminists, etc). But
still overlooked is the fundamental fact that science has a long history
of failing on its own terms, and on its own turf. Aristotle was a
modern scientist of his day, as was Ptolemy, and as of course were many
others. As these theorists and/or their theories fall into scientific
disfavor, the worker-bees of science kick these now unneeded drones out of
the hive into the cold of the winter of their discontent — or some such.
Like footsteps of the past in that journey of a thousand miles, they have served their purpose, that of
advancing science from whatever it was before to whatever it is that is
also about to be left behind. They are now an embarrassment, cut from the
team by a subtle variant of Occam’s Razor. Thus (the implicit
infallibility of) science is maintained.
The space program has endowed us with a special term
for this type of process. The early space capsules had heat shields of a
special design that would protect the capsule from the extremes of
re-entry temperatures and heat. These heat shields were made of a special
material composed with a large number of special potential “flakes”. Upon
re-entry, as the surface of the heat shield is heated by friction with the
atmosphere, these “flakes”, heated to extreme temperatures, will “take the
fall” and “take the heat”, away from the heat shield before it gets too
hot, and... away from the astronauts.
If this sounds social-political as
well as scientific, it should.
When science changes so much that the old paradigms
and their champions are too much of an embarrassment — people might start
questioning (the infallibility of) science as they did the infallibility
of religion — science, like so many others, practices a variant of
“ablative shielding” by casting out “flakes”, “fall guys”, who, “falling
from grace”, also “take the heat”... away from science. Thus, Aristotle,
Ptolemy, and many others were ejected from the pantheon of science, even
though they were leading “modern scientists” in their day. Kepler, on the
other hand, is still a close enough approximation to keep in the pantheon.
(Kepler (1571-1630) is lucky that the center of mass of the Sun is still
very close to the center of mass of the Solar System, or he’d be
outa here.)
Science deals with its critics in very much the same
way, and all too often with great, “righteous” anger. They are afraid of
any kind of shift that might... disenfranchise... them from their preeminent
position of power, a position and a power which the warnings of e.g. the
Bible unambiguously describe as a damnation (“... when He shall have put
down all rule and all authority and power”; check out 1st
Corinthians 15:24). Those who truly love science often feel an all too
actual terror at the current state of science’s... soul.
|
|
|
|
5.7 “Science Wars” and
“Scientific Revolution”
There is an impending shift in the relationship
between science and the world, somewhat like the “paradigm shifts” that
Thomas Kuhn wrote about in his “The
Structure of Scientific Revolutions” (University
of Chicago Press, 1962, 3rd Edition in 1996). The real
shift — and it will be a true apocalypse for some — will be a
“meta-paradigm” shift. There will be a conjoining of the “science wars”
with “scientific revolution”. The real revolution that this falling rate
result will encourage has to do with the terrors mentioned above. It is
not a source of terror that Newton’s law of gravity will be displaced and
replaced, and in any case it won’t be, at least not due to the result
presented here.
-
One source of the terror that will give impetus to a new and different
kind of scientific revolution is the one repeated so often here, that,
not only did Newton fail to note the rather obvious falling rate
difference that his own theory predicts, but every scientist since has
failed to, as well, including many brilliant ones. Another
source of the terror is the “righteous” anger that scientists express at
those who try to point out such... oversights. There is a pattern of...
oversights, and there is a corresponding pattern of anger.
-
This is science failing at its most fundamental levels.
-
This is science failing on its own terms.
The current heating up in the last few decades of the
millennia old “science wars” (a modern term for it) is still based mainly
on finding that science fails on philosophical-moral-ethical-social
grounds, e.g. regarding epistemology or “how we know what we know”, which
of course it does even though science rejects such grounds as...
“unscientific”. Add to this the terror we should all — especially
scientists — feel at the thought of people — especially ostensibly
competent scientists — getting angry when science is questioned, even when
questioned about such an accepted fundamental result.
The real revolution will be in world-community
awareness of this serious failure of science, and relatedly in our science
education, and we could say in meta-science, how we all — not just
scientists — do science. The questions are inescapable: If science has
overlooked something so theoretically obvious for over 300 years, and so
astronomically obvious for almost 100 years, what else is science...
overlooking?! What (Greek?!) fatal flaws is science burdened with,
and burdening our world community with?! Talk about “science wars”:
science failing on its own terms and its own turf...
There will be a meta-paradigm shift e.g. in our
communally accepting the actual, even the inherent, fallibility and
fragility of science. A subtly related idea is expressed in a recently
published book (this gets a bit complicated): In Chet Raymo’s review in
Scientific American (September, 2000) of Steve Fuller’s new book
Thomas Kuhn: A Philosophical History for Our Times (University
of Chicago Press, 2000), he has:
-
“The paradigms of normal science are not the ideal form of science, he
[Fuller] says, but rather ‘an arrested social movement in which the
natural spread of knowledge is captured by a community that gains relative
advantage by forcing other communities to rely on its expertise to get
what they want.’”
[Chet Raymo, quoting Steve Fuller]
It would be difficult for
science, as religion has also found, to maintain its status, to promote
its implicit “practically omniscient, practically infallible” image and
its explicitly “the only real way to go” image, if it admitted to...
oversights.
Community recognition of the falling-rate-difference...
oversight could very well help stimulate the already budding revolution of
how and why we do science in the larger sense. When we hold:
we will be far more likely
to insist on:
-
“when right, to be kept right;
-
when wrong, to be put right.”
We will find ourselves less
inclined to teach scientific jingoism or chauvinism to our children. We
will find that hypocrisy will make it impossible for anyone to win
the current “science wars”.
Science — and mathematics — still have many more
undiscovered... oversights. Discovery of these... oversights, or rather their
careful examination and the soul searching that will go with it, need not
make us sadder, but will help make us — both science and society — wiser.
If we don’t keep questioning accepted scientific beliefs, science will
literally die out, far more quickly and completely than the dinosaurs or
passenger pigeons, and perhaps take everyone else with it.

5.8 The Future of
Science and Its... Oversights
The science wars — and someday science itself —
will soon take a new turn. Not only critics, but lovers of science, as
well, will start taking the stance that...
Science must learn to come to terms with its...
oversights. It turns out that there are many, and some of them are far
more important than this albeit fascinating one, somewhat theatrically
referred to as “Newton’s Great... Oversight”. Science must also learn to
come to terms with its penchant for making... oversights and taking
sanctuary in denial, and even in “righteous” anger. This is accepted by
the community because of science’s reputation, a reputation that does not
include the possibility of any serious... oversights. Science must
learn that it is fundamentally fallible, that it can decidedly
fail, on its own terms, flagrantly, even in its fundamental tenets,
and for hundreds of years at a stretch, without noticing, and with anger
when there are attempts to question or “put right”. It is of telling
significance that... “oversights” will be easier for scientists to deal with
psychologically than “blunders”.
For Newton it can be considered a “great”... oversight,
but perhaps for other, lesser scientists it can be considered merely a
“normal”... oversight, an even more terrifying concept. In any case, dealing
with this oversight — the non-zero falling rate difference of lighter and
heavier bodies, and its consequences — will be useful in this regard,
since it is so obvious that no scientist since the time of Newton
should have missed it. It is easy to demonstrate both the falling rate
difference and its consequences in popular terms, without abstruse-arcane
or difficult mathematics. This will ease the way for the meta-paradigm
shift to take place, perhaps in less than a generation, a shift toward
transmuting... oversights into... insights.
