Although the Strong Force of QCD is a short range force while
Gravitation is supposed to be a long range force, they're surprisingly
similar from the viewpoint of "0 vs Infinity (Infinity coded as 1"
viewpoint.

Gravitation obeys classically:

1) F = Gm1m2/r^2

and so near the "origin" (the larger mass arguably) gravitation is
increases ("toward infinity").

The Strong (Gluon) Force of QCD, if the "origin" were located "at
infinity" or at the boundary of the Bag in the Bag model, would at
least piecewise be roughly approximated by (1) with the square possibly
a different positive power of r and with "attraction" replaced by
"repulsion", that is to say at the Bag Boundary there is infinite
repulsion away from the boundary.   Very close to the quark it is close
to 0, which is where the Unification Scale holds (see Howard Georgi's
paper "A unified theory of elementary particles and forces," Scientific
American April 1981, v. 244).

This fits in well with the Probable Influence/Causation (PI) theory in
which 0 and 1 correspond respectively to "0 versus infinity"
respectively, though the existence of a "Bag Boundary" suggests that a
microscopic/quantum "Bag" and a macroscopic Universe may be regarded as
different Universes with the former finite in length/width/breath when
viewed from the "perspective" of the second.   Arguably, a third
Universe "larger" than ours could view ours as having finite principal
radii.

Look up QCD as keyword on the internet, which brings up "too many
papers" on arXiv and over 80 papers in Front for the mathematics ArXiv.
The former truncates the number to 300 papers.

"Gluons" and "review QCD" bring up papers also in one or the other of
the above two sites.

PHYSICS EDUCATION: CRISIS OR DEATH?

http://www.guardian.co.uk/science/2005/nov/22/schools.g2
"But instead of celebrating, physicists are in mourning after a report
showed a dramatic decline in the number of pupils studying physics at
school. The number taking A-level physics has dropped by 38% over the
past 15 years, a catastrophic meltdown that is set to continue over
the next few years. The report warns that a shortage of physics
teachers and a lack of interest from pupils could mean the end of
physics in state schools. Thereafter, physics would be restricted to
only those students who could afford to go to posh schools. Britain
was the home of Isaac Newton, Michael Faraday and Paul Dirac, and
Brits made world-class contributions to understanding gravity, quantum
physics and electromagnetism - and yet the British physicist is now
facing extinction. But so what? Physicists are not as cuddly as
pandas, so who cares if we disappear?"

http://www.lewrockwell.com/orig6/ingdahl2.html
"But there has been a marked global decrease of students willing to
study physics, and funding has decreased accordingly. Not only that,
the best students are not heading for studies in physics, finding
other fields more appealing, and science teachers to schools are
getting scarcer in supply. In fact, warning voices are being heard
about the spread of a "scientific illiteracy" where many living in
technologically advanced societies lack the knowledge and the ability
for critical thinking in order to function in their daily
environment."

Harry Kroto: "The wrecking of British science....The scientific method
is based on what I prefer to call the inquiring mindset. It includes
all areas of human thoughtful activity that categorically eschew
"belief", the enemy of rationality. This mindset is a nebulous mixture
of doubt, questioning, observation, experiment and, above all,
curiosity, which small children possess in spades. I would argue that
it is the most important, intrinsically human quality we possess, and
it is responsible for the creation of the modern, enlightened portion
of the world that some of us are fortunate to inhabit. Curiously, for
the majority of our youth, the educational system magically causes
this capacity to disappear by adolescence.....Do I think there is any
hope for UK? I am really not sure."

"Physicien au CEA, professeur et auteur, Etienne Klein s'inquiète des
relations de plus en plus conflictuelles entre la science et la
société. (...) « Je me demande si nous aurons encore des physiciens
dans trente ou quarante ans », remarque ce touche-à-tout aux multiples
centres d'intérêt : la constitution de la matière, le temps, les
relations entre science et philosophie. (...) Etienne Klein n'est pas
optimiste. Selon lui, il se pourrait bien que l'idée de progrès soit
tout bonnement « en train de mourir sous nos yeux ». (...) Cette
perception d'une « science mortifère » se double d'une « culture du
ressenti », sorte de sésame passe-partout utilisé pour justifier
l'acquisition, l'évaluation ou le rejet des connaissances. « J'ai eu à
faire récemment à un jeune étudiant en sciences qui n'était pas
d'accord avec la théorie de la relativité d'Einstein pour une raison
étonnante : il m'a dit qu'il ne la sentait pas », indique-t-il en
riant à moitié. Au bout du compte, ce soupçon d'imposture permanente
débouche sur une idée simple qui fait des ravages : « En sciences
comme ailleurs, tout est relatif. » Dans ce contexte, la vulgarisation
est d'un maigre secours car « la pédagogie ajoute du bruit et augmente
la confusion »."

"L'Occident face à la crise des vocations scientifiques. Le mal
s'accroît, mais le diagnostic s'affine. Les pays développés, qui
souffrent, sans exception, d'une désaffection des jeunes pour les
filières scientifiques, pointent du doigt la façon dont les sciences
sont aujourd'hui enseignées. Trop de théorie, pas assez de pratique ;
des enseignements qui n'invitent pas au questionnement... (...) ...les
sciences physiques, grandes victimes de ce rejet collectif des jeunes
Européens, dégringolent (- 5,5 %)."

"PHYSICS IN TERMINAL DECLINE? In CEER's latest report, published 11
August 2006 and funded by the Gatsby Charitable Foundation, Professor
Alan Smithers and Dr Pamela Robinson show that the decline in physics
as student numbers fall and university departments shut is more
serious than is generally appreciated."

http://www.wellingtongrey.net/articles/archive/2007-06-07--open-letter-aqa.html
"I am a physics teacher. Or, at least I used to be. My subject is
still called physics. My pupils will sit an exam and earn a GCSE in
physics, but that exam doesn't cover anything I recognize as physics.
Over the past year the UK Department for Education and the AQA board
changed the subject. They took the physics out of physics and replaced
it with... something else, something nebulous and ill defined. I worry
about this change. I worry about my pupils, I worry about the state of
science education in this country, and I worry about the future
physics teachers - if there will be any. (...) UPDATE 2009:  After
much frustration I'm leaving teaching England in physics.  I've
started a side business in time management and am taking a break from
the profession."
