SYMPTOMS OF DEAD SCIENCE |
http://www.nyas.org/ebrief/miniEB.asp?eBriefID=687
"In particular, the Second Law of Thermodynamics dictates that entropy
in a physical system will increase as time passes. This has
ramifications on cosmological scales in the inflationary model of our
universe, which posits that there was an initial singularity and that
since the Big Bang, the universe has been expanding."
http://philsci-archive.pitt.edu/archive/00000313/
Jos Uffink: "This summary leads to the question whether it is fruitful
to see irreversibility or time-asymmetry as the essence of the second
law. Is it not more straightforward, in view of the unargued
statements of Kelvin, the bold claims of Clausius and the strained
attempts of Planck, to give up this idea? I believe that Ehrenfest-
Afanassjewa was right in her verdict that the discussion about the
arrow of time as expressed in the second law of the thermodynamics is
actually a RED HERRING."
Whether the law of entropy increase is a RED HERRING or not would be
a problem in a different world. In Einstein zombie world the universal
solution is: Who cares. Some can make money and career by applying
this law. Bravo! Cleverer scientists can show it is a RED HERRING.
Bravo again! Cleverer scientists will also be given some money.

A key symptom is that Pentcho does not misunderstand or
misrepresent a dead science. Motivations are left to the
reader's imagination. Suffice it to say, if it is moving,
Pentcho shoots at it.

Similarly, some Einsteinians fiercely teach that, in a gravitational
field, the speed of light is CONSTANT:
http://www.astronomynotes.com/relativity/s4.htm
"Prediction: light escaping from a large mass should lose energy---the
wavelength must increase since the speed of light is constant.
Stronger surface gravity produces a greater increase in the
wavelength. This is a consequence of time dilation. Suppose person A
on the massive object decides to send light of a specific frequency f
to person B all of the time. So every second, f wave crests leave
person A. The same wave crests are received by person B in an interval
of time interval of (1+z) seconds. He receives the waves at a
frequency of f/(1+z). Remember that the speed of light c = (the
frequency f) (the wavelength L). If the frequency is reduced by (1+z)
times, the wavelength must INcrease by (1+z) times: L_atB = (1+z)
L_atA. In the doppler effect, this lengthening of the wavelength is
called a redshift. For gravity, the effect is called a GRAVITATIONAL
REDSHIFT."
http://helios.gsfc.nasa.gov/qa_sp_gr.html
"Is light affected by gravity? If so, how can the speed of light be
constant? Wouldn't the light coming off of the Sun be slower than the
light we make here? If not, why doesn't light escape a black hole?
Yes, light is affected by gravity, but not in its speed. General
Relativity (our best guess as to how the Universe works) gives two
effects of gravity on light. It can bend light (which includes effects
such as gravitational lensing), and it can change the energy of light.
But it changes the energy by shifting the frequency of the light
(gravitational redshift) not by changing light speed. Gravity bends
light by warping space so that what the light beam sees as "straight"
is not straight to an outside observer. The speed of light is still
constant." Dr. Eric Christian
Other Einsteinians have read Divine Albert's writings more carefully
and accordingly teach that, in a gravitational field, the speed of
light is VARIABLE:
http://www.math.ucr.edu/home/baez/physics/Relativity/SpeedOfLight/speed_of_light.html
"Einstein went on to discover a more general theory of relativity
which explained gravity in terms of curved spacetime, and he talked
about the speed of light changing in this new theory. In the 1920 book
"Relativity: the special and general theory" he wrote: ". . .
according to the general theory of relativity, the law of the
constancy of the velocity of light in vacuo, which constitutes one of
the two fundamental assumptions in the special theory of relativity
[. . .] cannot claim any unlimited validity. A curvature of rays of
light can only take place when the velocity of propagation of light
varies with position." Since Einstein talks of velocity (a vector
quantity: speed with direction) rather than speed alone, it is not
clear that he meant the speed will change, but the reference to
special relativity suggests that he did mean so."
http://www.physlink.com/Education/AskExperts/ae13.cfm
"So, it is absolutely true that the speed of light is _not_ constant
in a gravitational field [which, by the equivalence principle, applies
as well to accelerating (non-inertial) frames of reference]. If this
were not so, there would be no bending of light by the gravitational
field of stars....Indeed, this is exactly how Einstein did the
calculation in: 'On the Influence of Gravitation on the Propagation of
Light,' Annalen der Physik, 35, 1911. which predated the full formal
development of general relativity by about four years. This paper is
widely available in English. You can find a copy beginning on page 99
of the Dover book 'The Principle of Relativity.' You will find in
section 3 of that paper, Einstein's derivation of the (variable) speed
of light in a gravitational potential, eqn (3). The result is,
c' = c0 ( 1 + V / c^2 )
where V is the gravitational potential relative to the point where the
speed of light c0 is measured."
http://www.blazelabs.com/f-g-gcont.asp "The first confirmation of a
long range variation in the speed of light travelling in space came in
1964. Irwin Shapiro, it seems, was the first to make use of a
previously forgotten facet of general relativity theory -- that the
speed of light is reduced when it passes through a gravitational
field....Faced with this evidence, Einstein stated:"In the second
place our result shows that, according to the general theory of
relativity, the law of the constancy of the velocity of light in
vacuo, which constitutes one of the two fundamental assumptions in the
special theory of relativity and to which we have already frequently
referred, cannot claim any unlimited validity. A curvature of rays of
light can only take place when the velocity of propagation of light
varies with position."......Today we find that since the Special
Theory of Relativity unfortunately became part of the so called
mainstream science, it is considered a sacrilege to even suggest that
the speed of light be anything other than a constant. This is somewhat
surprising since even Einstein himself suggested in a paper "On the
Influence of Gravitation on the Propagation of Light," Annalen der
Physik, 35, 1911, that the speed of light might vary with the
gravitational potential. Indeed, the variation of the speed of light
in a vacuum or space is explicitly shown in Einstein's calculation for
the angle at which light should bend upon the influence of gravity.
One can find his calculation in his paper. The result is c'=c(1+V/c^2)
where V is the gravitational potential relative to the point where the
measurement is taken. 1+V/c^2 is also known as the GRAVITATIONAL
REDSHIFT FACTOR."
Where is the truth? Is there a solution to the problem? Is the speed
of light in a gravitational field CONSTANT or VARIABLE? Of course
there is a solution. There is a solution to all problems in Einstein
zombie world. The solution is: Who cares.

The cleverest Einsteinian:
http://philsci-archive.pitt.edu/archive/00001743/02/Norton.pdf
John Norton: "Einstein regarded the Michelson-Morley experiment as
evidence for the principle of relativity, whereas later writers almost
universally use it as support for the light postulate of special
relativity......THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE
WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT
POSTULATE."
The most famous Einsteinian:
http://www.hawking.org.uk/lectures/dice.html
Stephen Hawking: "Both Mitchell and Laplace thought of light as
consisting of particles, rather like cannon balls, that could be
slowed down by gravity, and made to fall back on the star. But a
famous experiment, carried out by two Americans, Michelson and Morley
in 1887, SHOWED THAT LIGHT ALWAYS TRAVELLED AT A SPEED OF ONE HUNDRED
AND EIGHTY SIX THOUSAND MILES A SECOND, NO MATTER WHERE IT CAME FROM."

An international team of leading philosophers and physicists:
http://www.amazon.com/Relativity-Simultaneity-Routledge-Contemporary-Philosophy/dp/0415701740
"Einstein, Relativity and Absolute Simultaneity is an anthology of
original essays by an international team of leading philosophers and
physicists who, on the centenary of Albert Einsteins Special Theory of
Relativity, come together in this volume to reassess the contemporary
paradigm of the relativistic concept of time."
A distinguished member of the international team of leading
philosophers and physicists:
http://philosophy.ucsd.edu/faculty/ccallender/
"On Finding 'Real' Time in Quantum Mechanics" (draft) Absolute
Simultaneity. (Eds) W.L. Craig and Q. Smith. NY: OxfordUniversity
Press, 2007.
Craig Callender: "In my opinion, by far the best way for the tenser to
respond to Putnam et al is to adopt the Lorentz 1915 interpretation of
time dilation and Fitzgerald contraction.1 Lorentz attributed these
effects (and hence the famous null results regarding an aether) to the
Lorentz invariance of the dynamical laws governing matter and
radiation, not to spacetime structure. On this view, Lorentz
invariance is not a spacetime symmetry but a dynamical symmetry, and
the special relativistic effects of dilation and contraction are not
purely kinematical. The background spacetime is Newtonian or neo-
Newtonian, not Minkowskian. Both Newtonian and neo-Newtonian
spacetime include a global absolute simultaneity among their invariant
structures (with Newtonian spacetime singling out one of neo-Newtonian
spacetime's many preferred inertial frames as the rest frame). On
this picture, there is no relativity of simultaneity and spacetime is
uniquely decomposable into space and time."

The cleverest Einsteinian:
http://www.pitt.edu/~jdnorton/papers/companion.doc
Einstein's Special Theory of Relativity and the Problems in the
Electrodynamics of Moving Bodies that Led him to it.
John Norton: "Einstein's second postulate, the light postulate,
asserts that "light is always propagated in empty space with a
definite velocity c which is independent of the state of motion of the
emitting body." EINSTEIN GAVE NO JUSTIFICATION FOR THIS POSTULATE IN
THE INTRODUCTION TO HIS PAPER. ITS STRONGEST JUSTIFICATION came from
Maxwell's electrodynamics. That theory had identified light with waves
propagating in an electromagnetic FIELD and concluded that just one
speed was possible for them in empty space, c = 300,000 km/sec, no
matter what the motion of the emitter."
Divine Albert:
http://www.perimeterinstitute.ca/pdf/files/975547d7-2d00-433a-b7e3-4a09145525ca.pdf
Albert Einstein: "I consider it entirely possible that physics CANNOT
BE BASED UPON THE FIELD CONCEPT, that is on continuous structures.
Then nothing will remain of my whole castle in the air, including the
theory of gravitation, but also nothing of the rest of contemporary
physics."

"We are nearing the end of the "World Year of Physics", otherwise
known as Einstein Year, as it is the centenary of his annus mirabilis
in which he made three incredible breakthroughs, including special
relativity. In fact, it was 100 years ago yesterday that he published
the most famous equation in the history of physics: E=mc2. 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."
http://education.guardian.co.uk/universitiesincrisis/story/0,,2084784,00.html
Nobel laureate Harry Kroto: "The wrecking of British
science.....Thirty per cent of physics departments have either been
closed or merged in the past five years.....Do I think there is any
hope for UK? I am really not sure."

The most "critical" Einsteinian:
http://www.nyas.org/publications/UpdateUnbound.asp?UpdateID=41
Lee Smolin: "Then, about 30 years ago, something changed. The last
time there was a definitive advance in our knowledge of fundamental
physics was the construction ofthe theory we call the standard model
of particle physics in 1973. The last time a fundamental theory was
proposed that has since gotten any support from experiment was a
theory about the very early universe called inflation, which was
proposed in 1981......I should emphasize that this crisis involves
only fundamental physics....."
The hypocrisy of the most "critical" Einsteinian:
http://newhumanisteditor.blogspot.com/2007/04/whats-up-with-physics.html
"And finally, but by no means least, he [Lee Smolin] enters an
eloquent plea on behalf of the mavericks, the loners, the original
thinkers, the sceptics, the unusual and eccentric minds, who he
believes are needed to free theoretical physics from the impasse it
currently finds itself in. It is a plea to the institution of physics
- to physics-2 - to make room for such people, because without them
physics-1 is in danger of losing connection with the real world and
the strict control of empirical testing."
"The mavericks, the loners, the original thinkers, the sceptics, the
unusual and eccentric minds" die in oblivion after questioning
Einstein's false light postulate:
http://www.ekkehard-friebe.de/wallace.htm
Bryan Wallace: "Einstein's special relativity theory with his second
postulate that the speed of light in space is constant is the linchpin
that holds the whole range of modern physics theories together.
Shatter this postulate, and modern physics becomes an elaborate
farce!....The speed of light is c+v."

John Barrow: " Einstein restored faith in the unintelligibility of
science. Everyone knew that Einstein had done something important in
1905 (and again in 1915) but almost nobody could tell you exactly what
it was. When Einstein was interviewed for a Dutch newspaper in 1921,
he attributed his mass appeal to the mystery of his work for the
ordinary person: "Does it make a silly impression on me, here and
yonder, about my theories of which they cannot understand a word? I
think it is funny and also interesting to observe. I am sure that it
is the mystery of non-understanding that appeals to them...it
impresses them, it has the colour and the appeal of the mysterious. "
