I have not had any time for physics recently and expect this unfortunate

state of affairs will persist for awhile longer, but I did want to bring

forth a recent "behind the scenes" discussion between one individual

poster, and the moderators. That individual made the statement, which

which I could not agree more, that:

state of affairs will persist for awhile longer, but I did want to bring

which I could not agree more, that:

The "corruption of physics by mathematicians (not mathematics) has been

burgeoning for over 100 years with today's dismal lack of progress a

predictable result."

Again, this struck me very hard, and jostled me out of my present

hibernation, for I could not agree more.

Mathematicians in my view (and experience) have become the "crabs in the

barrel" of physics, dragging back and bullying any physicist (and there

is a sharp difference between a physicist and a mathematician) who tries

to advance forward without paying endless homage to some mathematical

hobby horse or another. A good, creative physicist trying to build new

wings onto our edifice of natural understanding must be willing more

often than not to take risky stabs in the dark based on informed

physical intuition, without any particular mathematical preconceptions,

and then to come back afterwards after the dust settles and sort out

what sort of mathematics he or she has wandered into or stumbled upon.

The insistence on constricted pedagogical pathways to discovery suggests

that we can get from "here to there" using only the tools which are

already within the scope of human knowledge, when much of our scientific

history shows that this is just not true. Talk about ignoring evidence!

I am often appalled a) not only at the complete lack of connection

between much of what I read in the physics literature and any sort of

direct intuitive feeling about nature, and even more so, b) the complete

willingness on the part of most participants to accept this state of

affairs without so much as a raised eyebrow.

Remember folks, physics is about nature -- not about mathematics. It

is, in essence, natural philosophy made precise and measurable. I can

churn out pages of mathematics as fast as anybody, but one always has to

be able to see and feel a connection to nature. And without an

underlying natural philosophy to guide the way, one is lost.

So there has been no advancement in 100 years? This obviates

general relativity and most of quantum mechanics to "dismal lack

of progress"? Even your own efforts...

We have finite lifetimes, even as a species. Manipulation of

what is known, by the "bridge building" by mathematicians is not

always a, how did Jesus say it, "vain repetition". It really

does direct us through spaces already known, so that "setting off

for novel investigation" is truly orthogonal to the solution

space of current theory.

The expectation that many mathematicians have that we appreciate

their particular ivory tower is annoying, but I don't believe

that alone is limiting our horizon.

"How do you shoot a purple elephant?"

"With a purple elephant gun."

"How do you shoot a pink elephant?"

Personally, I think a lot of people cannot see that it isn't

about elephants or guns. They just spend a lot of time figuring

out how to make purple elephants...

Welcome back to the real world. I could not have said it better

myself. Maybe you are now ready to take a real look at the Discrete

Fractal Paradigm. This summer I found that the full Kerr-Newman

solution of the Einstein-Maxwell equations gives 8.13 x 10^-14 cm for

the proton's radius and 1.67 x 10^-24 g for the proton's mass. Not

bad, huh?

100 years ago, 1908, Minkowski *invents* SpaceTime,

and then before he perfected it, died, leaving us with

a great idea, but a mathematical monstrosity that I'm

still trying to figure out, http://physics.trak4.com/

We have these two highly mathematical theories,

GR and QT (with nearly countless spin-off acronyms,

like QM, WM, QED, QFT ...) that have an excellent

empirical foundation, that's a lot of RED tape, so we're

*boxed in* mathematically.

Personally, I think we need to evolve our math to the

new challenges, as Newton did via calculus applied

to the Theory of Gravity, and that evolution may turn

out to be a simplification.

It is even worse than that. We already have started going backwards.

In my university (where I'm doing my PhD work in general relativity)

the physics students are conditioned by "mathematical physicists" into

believing that the principle of conservation of energy is "not valid

in general relativity" (without a proof, just on the authority of the

professor and one has to mention that this "general relativity" is a

particular kind of relativity in which the universe is believed to be

expanding and so obviously energy in it has to be created "somehow" to

counter the natural in relativistic gravitation reshift of photons,

the redshift due to the necessary time dilation in curved space in

which redshift per unit of distance must be 1/R where R is radius of

curvature of space since 1/R+d^2(proper time)/dtdx=0, where (t,x) is

the coordinate spacetime). So the matematicians to keep alive their

outdated hypthesis that the universe is expanding (while observations

turned out to be contradicting the expansion) are not only preventing

the publication of evidence contradicting the expansion but are also

corrupting the minds of physics students. It is probably too late to

do anything about it which must make the "crabs in the barrel" very

happy.

and what progress we had in general relativity, which is able to (i)

predict Hubble redshift in "Einstein's (stationary) universe" and

predicts the value of Hubble constant as observed (as c/R_E, where c

is speed of light and R_E is "Einstein's radius"), is able to (ii)

predict the ilusion of accelerating expansion and predict its value as

observed (as (dH/dt)/H_0^2=1/2), (iii) predict local quasars (as seen

by Halton Arp), (iv) predict average size of pieces of non luminous

matter (as ca. 2 m), (v) possibly predict the relation between the

redshift and angular diameters of galaxies as observed, (vi) predict

the Pioneer "anomaly" as observed (as c^2/R_E) and because of

mathematicians working "in the universe" none of those predictions of

genereal relativity got through to the public opinion because those

mathematicians who are responsible for math of general relativity were

unable to accept that thier model of the universe (so called the Big

Bang model) is not what is out there.

I cannot agree at all. The course of the last 60 years at least has been

one in which mathematicians are kept out of physics and in which the

standards of mathematics applied to physics are inadequate to deal with

the fundamental problems facing physics. Physicists, not mathematicians,

impose the philosophy that the physics consists only of experimental

predictions, not the validity of the arguments or of the assumptions.

Mathematicians, otoh, know that if a implies b, and b is true, you

cannot deduce a.

Indeed, but the blame lies with the philosophies of physics, not with

mathematicians.

I would say that it's related to a kind of philosophical revolution

that was perhaps started by Einstein: the idea was, I think, that when

physical intuition doesn't get you there, smart mathematical juggling

based on principles without focussing on a model can give physics

quite a boost (and so it did, at least the first years). Regretfully

the use of physical models has since been degraded, while I think that

the most succesful long-term approach is a double approach. For the

rest, I can't agree more with your posting!

The problem with math is of course such that the model it describes is

often not what is really out there. The classical illustration of this

fact is Newtonian gravitation. What Newton missed was "only" the

curvature of space. Otherwise it was (almost) perfect. So perfect that

till now many people refuse to accept the curvature of space as

physical fact and hope that some new discoveries (e.g. of some "dark

energy") make Einstein's gravitation invalid and so they don't need to

learn the physics of it. Ironicaly it applies mostly to mathematicians

who are trying to make snese of the so called "expanding universe"

while the universe is most likely stationary or at least there are no

observations yet that would contradict "Einstei's universe". At this

point I expect trouble with moderators but luckily what I have said

could be proved rather easily if the moderators were really interested

in physics more than in moderating. I've been working on "expandng

universe" since 1985 and I discovered a beautiful confirmation of

Einsteinian gravitation and the confirmation of strict conservation of

energy, that mathematicians who "work in the universe" for some reason

refuse to accept.

They also refuse to accept the fact that "Pioneer anomaly" is an

artifact produced by lazy astrophysicists who don't want to bother

with the understanding of Einstein's gravitation (since "dark energy"

is going too invalidate it soon, right?) and for the time being they

created a cow that they will be able to milk foever since if this

"anomaly" can't be explained with Einstein's gravitation (as they

maintain) it must be an "unexplained phenomenon" on which one may work

forever since the only sensible solution has been already rejected as

contradicting the hypothesis of "expanding universe" ("acidentally" he

photons show the same "dynamical friction" as Pioneers do but it must

be purely accidental since photons have their redshift declared to be

only because of "expanding space").

I would have to say that statement is "way over the top" and I don't

agree with it at all. I was actually quite "surprised" that you

posted this. ;-) Whilst we may have not had progress recently, there

has been an incredible amount of progress in physics over the last 100

years. Experimental physics gets exponentially more costly as we find

out more. Plus physics has progressed to the state where it is

impossible to describe adequately without mathematics.

Yes, David, this type of philosophical criticism does cast a long

shadow over these two 'triumphs' of 20th century theoretical physics.

But let's look a little closer.

First QM: we are not much further ahead in the study of atomic physics

than Sommerfeld in 1916 who just applied Planck's Proposal for

relativistic mass to Bohr's Keplerian model of the hydrogen atom.

Yes, I know someone will quote QED and tell me to how many decimal

places they can calculate the Lamb Shift but Ptolemy did a better job

than Galileo in predicting planetary movements; numerical agreement

with experiment is nice but insufficient if it does not provide

insight. Dirac himself came to admit this whole approach was deeply

flawed & in need of new foundational insights. These will be based on

new physical intuitions, not math deductions; the mathematicians have

had nearly 100 years to explore the math implications & are still

constructing their 'castles in the air'.

I'm not going to waste any time on GR - this is not an experimental

science but one limited to predicting cosmological numbers; as such it

contributes little more value to humanity than astrology. As I

described in my reply to Jay above, SRT is not about LT or Minkowski

'space-time' but Planck's relativistic mechanics, which were developed

to 'fit' crude experimental data. Theories about space itself are

simply metaphysics (like Clerk-Maxwell's aether) and should not form

the basis for an empirical science like physics, which used to be the

study of matter and change i.e. reality.

Thanks, Jay. As the poster who stimulated this thread I feel

obligated to contribute to it. My readings in the history of physics

lay the blame for the present mess in theoretical physics squarely at

the door of one of the heros of modern physics, namely: Max Planck.

Not only did he play the political game masterfully around the

beginning of the 20th century as private advisor on physics to the

Prussian Ministry of Education (who controlled most of the academic

professorships) but as editor of 'Annalen der Physik' he could promote

those who agreed with his personal (Platonic & math) viewpoint. Thus,

he was Einstein's earliest (& strongest supporter). As a

mathematician he was very good at 'back-tracking' through a theory

until he could propose a new equation that took the deductive theory

along a new direction, one whose results he knew were required by

experiment. This had nothing to do with philosophical or visual

models that had characterized the rapid evolution of physics in the

previous 200 years but was totally in the pure 'head-space' tradition

of creative math. His two most notorious examples of this technique

were his quantum suggestion for energy transfers between harmonic

oscillators to fit the experimental facts of the black-body spectrum

and his proposal to modify the invariant mass of a fast-moving body to

fit the experimental results of Kaufmann. The first suggestion

ultimately resulted in the quantum theory and the second relativistic

mechanics. Since both suggestions were purely mathematical and

without physical explanation then the foundations of these two new

theories of 20th century physics were 'built on sand' - the nearly 100

years of argumentation about the physical interpretation of these two

theories was then inevitable. How ironic that Planck subsequently

came to dislike the two major directions of theoretical physics that

his approach has 'hatched'. This style of doing theoretical physics

then became the norm as more & more students with a strong penchant

for mathematics were inducted into the physics profession to teach

these types of math theories. Any young student with an interest in

philosophy or visual model building was soon turned off by this

approach, accelerating the concentration of mathematicians in

theoretical physics, where today the incidence of these 'cuckoos' is

close to 100%. It is not surprising that not only has progress

stalled in theoretical physics but that the number of students

entering physics today has dropped precipitously. Unless this

situation is soon remedied then (irony of ironies) theoretical physics

will become just another activity of the math department.

Newton did not invent math to discover new physics. You have the cart

before the horse. Newton developed his innovative concepts first &

then used math to CALCULATE his results so that they might be compared

with observations. This would be like doing a telephone sampling

survey to calculate the average income of a country: asking everyone

takes too long & hardly changes the answer. In the case of

gravitation, the approximation of instantaneous effects between the

various planetary objects is sufficiently accurate compared to their

periods of rotation. Newton first had to invent the idea of universal

gravitation - that was his genius, not the calculus, which several

others were on the brink of inventing (vide - the Leibniz

contoversy). As Einstein recognized, inspiration precedes imagination

& then you do the math.

I cannot disagree with you more, Charles. Today, in the physics

departments around the world, there is an abysmal lack of interest in

both the philosophy and history of science. In my view, this is

because, like Jay, I see theoretical physics today almost totally

hijacked by the mathematicians. These individuals already have a

philosophy (Plato's Pythagoreanism) and do not wish to defend it.

Just like the Soviets (or the Catholics in the Middle Ages), it is

much simpler to silence one's critics than to defend one's own

position (the role of today's professional journal referees -

hopefully, not that of Google newsgroup moderators!)

You appear to suggest that the mathematicians in the physics

departments are not up to the standard of those left in the math

departments & if only these 'purists' would deign to do some physics

then the problems would disappear. Quite the contrary, this would

complete the hijacking of physics - these pure mathematicians have no

physical intuition whatsoever. The only good outcome is that it would

decelerate the progress of physics more rapidly to zero, so that they

could all get turfed out and we could get back to doing physics like

the giants of the 19th century.

Well, I've always felt that people who try to build new physical

theories on purely mathematical motivations are almost always doomed

to failure. And while such programs may lead to new and interesting

math, there's usually no physical content at all. Einstein's quest

for a unified field led to some fascinating new math, but no real

physics was discovered. Sometimes, I think string theory has led us

down a similarly mathematically-elegant, but void of physics dead

end. In the end, nothing beats a purely physical motivation for a

physical theory, as difficult as that can sometimes be.

Actually, Fred, I will retract any inferred agreement with the time

frame of 100 years, which was part of the original quote I reacted to.

As you know, the geometrization of gravitation in general relativity is,

in my view, the best that science has ever had to offer, and my own

natural philosophy regards this as the clear template for other

theoretical development. I am, as I have stated in other contexts, an

unrepentant proponent of Wheeler's geometrodynamic programme.

But certainly the last half century (with the notable exception of

electroweak theory) has been defined more by slogging through a morass

than by any groundbreaking new insights. QFT, as nice as it is, if

still an amalgamation of many threads, and the most coherent picture

that I have seen is that presented by Zee, in which quantum theory via

the path integral approach is, in essence, entails ever-more

sophisticated ways of playing with Gaussian integrals.

While all leads me to another thread I will start in a moment.

That requires individuals who are all three, mathematician, physicist,

String theory is motivated by metaphysics, not mathematics. It attempts

to deal with mathematical problems in qft, but rather one should look at

the mathematical structure of qft to see what it really means. I do not

see string theory doing that. It takes mathematical structure for

The concept of dark energy does not make Einstein's gravitation invalid.

It is just another word for Einstein's cosmological constant. The modern

concordance model is a solution of Einstein's field equation, i.e. it is

entirely within Einstein's theory of gravitation. It has flat space, but

it does not have flat spacetime.

Sure, his quest was based on real physics, but most of his attempts at

unification were more about tweaking the mathematics to see what would

happen rather than finding an actual physical motivation. SR

essentially began with questions about light, and GR with the

equivalence principle. After those successes, his approach seemed to

be to fiddle with the math and hope that something related to physics

would pop out. And I never said his quest was misguided, but that his

approach was basically flying blindly in a land of what if. For what

it's worth, I always felt that he probably came closest to physical

reality when he was working with Kaluza-Klein geometry.

His fundamental requirement was consistency. That should still be the

fundamental requirement. Consistency is demonstrated through

mathematics. If areas of physics are not consistent, we must adjust our

fundamental assumptions or postulates such that they better represent

physics. On cannot say the method is doomed to failure. Einstein had

already shown how successful it can be by producing both the special and

the general theories, plus his work on Brownian motion and the

photoelectric effect. He did not succeed with unification because he did

not take on board the quantum theory, and because qed was not available,

but one man can only do so much. It is not Einstein's failure, but

rather the failure of subsequent generations of physicists that they

have not appreciated or used Einstein's methods in the context of more

recent discoveries.

The real breakthroughs in physics have always been conceptual.

Maxwell was quite 'sloppy' in his math, Heaviside ignored his academic

critics & invented operator calculus, the delta function & vectors

(not bad, for an auto-didact) & Einstein was famous for his concepts

not his math. 'Proper standards' (in math) don't seem to have

contributed anything to the progress of physics in the past.

Your impled approach, Charles would rapidly empty out the physics

departments of all undergraduate students, leaving even more seats for

kids with only an aptitude for math. One can sympathize with Alfred

Nobel who refused to fund any prize for mathematics (although his

wishes have been subverted by the 'theoretical physicists') as he must

anticipated their lack of contributions 'to the benefit of mankind'.

You do me an injustice; all my degrees are in physics from a most

reputable English university; I suspect, Charles, that all of yours

were all in mathematics. Incidentally, I would agree with your

requirements but would totally reverse the order of their importance.

I am not holding my breath waiting for the 'fundamental issues' to be

solved by any mathematician (including all those string theorists).

I don't deny it. Mathematics is the study of concepts.

Not bad, but the delta function is usually credited to Dirac.

The standards of mathematics only need to be sufficient for the problem

in hand. QED is the first subject in physics in which divergences have

played an important role. The response of physics has been to continue

to ignore proper mathematical treatment of divergence, and to base

further theory on the errors in the sloppy treatment.

Not the physics departments, but I would make theoretical physics a

subject in which mathematical training is a prerequisite, and, instead

of teaching undergraduates the "shut up and calculate" interpretation,

telling them (as I was told) that if you try to think about why the laws

of quantum theory obtain, I would encourage mathematicians who want to

think about the whys of quantum theory rather than its application.

Agreed, creative mathematicians, philosophers, etc are all original

imagineers but philosophers try to ground their concepts in reality -

mathematicians are free to let their ideas float off into eternity, as

we've seen in physics this last 100 years.

True, but history doesn't always get it right. Dirac (first trained

in Bristol as an electrical engineer) actually credits the

'derivative' of the step function to Heaviside (another EE, who was

quite happy using pulses). Lorentz was notorious for taking ideas

from others without due creditation (e.g. the 'Lorentz' gauge invented

in 1867 by Ludwig Valentin Lorenz not Hendrik Antoon; the 'Lorentz'

transform, first pioneered by Voigt, improved by Heaviside & completed

in 1901 by Larmor).

The divergences in QED are the inevitable result of using calculus

throughout space including infinitely small separations between

interacting 'fields' (Dyson). As Dirac finally admitted, this lousy

math is an indication of a wrong theory. He wished he had never

started this whole rotten affair. Like Einstein, he died a very

frustrated man; both victims of obsessing on 'beautiful' (but wrong)

mathematics.

Almost fully agree on this one, except I wouldn't just be recruiting

kids with a math aptitude - I would seek out those with a real

physical intuition (more women) - like engineers and technologists

(the guys who really transform the world!) & don't over-expose them to

mathematics, it will surely stunt their imaginations.

Actually no; not for improving the lives of mankind, except for

Heaviside who proposed using the upper atmosphere for 'bending' radio

waves around the Earth: the technique needed for long-range wireless

communications. But then the dear academics refused to nominate him

for the Nobel in physics : "I mean, the fellow never even got a

degree, what would people think?".

Newton was not prepared to suggest any new ENTITY as the substance of

gravity; a very worthy approach (he just proposed a new universal

PROPERTY of matter). This conservative approach (Bill Ockham's) is to

be distinguished from the present penchant for inventing unobservable

'elementary particles' (e.g. quarks and 'strings') as new entities to

'explain' the world. I had hoped that we had learned Newton's lesson:

the world is not like chocolate cake but old (Greek) habits die hard.

The essence of 'quality' is the ordering of choices. Selecting new

physics undergraduates forces one to weigh varying personal strengths

differently. Unfortunately, math is easier to teach (deductive) and

far easier to examine (correct answers) so that selecting on math

scores alone becomes much more 'objective'.

On this last point we can agree 100%.

Well, Charles, after this 'minor' response I'm goint to call it a day

on this one. I've certainly enjoyed jousting with you on this topic

(one of my personal bugaboos) but I have more work to do (& time

really is of the essence). I'm sure you will (as moderator) have the

final say.

Good hunting, 'maxwell'.

I think we should recognise that the problems started with the divorce

of maths from physics, and really post war not 100 yrs, though the seeds

were sewn earlier, with the failure of interpretations of quantum theory

and the rise of quantum field theory.

It is the Lorenz gauge, and only mispelled and miscreditted by those who

Do not underestimate the worth of the summation convention, a simple

thing perhaps, but isn't it a measure of genius to notice something

simple that everyone else overlooks. Also, he discovered absolute

parallelism independently of Cartan, known as the best geometer in

Europe, and is one of only a few relativists to pay heed to

inconsistency between gr and cem.

True. They can be fixed by removing these infinitely small separations

from the theory. This is necessary, on physical grounds, to a theory of

particle interactions, which is as I have described on my website. It is

also necessary on mathematical grounds, else the theory is not defined.

If they actually did take a mathematical approach, the divergences would

not be allowed.

Yeah, but the theory is only a little bit wrong. This is the problem

with physicists thinking the underlying entities are fields, not

particles. That is in turn rooted in philosophical and interpretational

issues which they refuse to address.

The theory of gravitation with flat space is called "Newton's theory"

and it happens to be a wrong theory (inconsistent with observations).

conserved in gtr, while they can't be conserved only in curved

spacetime. If our spacetme happens to be flat (as the calculations of

redshift in stationary space suggest) then there is also global

is no reason to assume that spacetime isn't flat if rather simple

I agree that this issue should be considered in a more differentiate manner

indeed, 'Heaviside's step function' is commonly accepted - 'history' is

written by (wo)men => often not fair

this statement is a logical triviality on the one hand and wrong on the other

hand that accounts for the possible badness of human characters

most authors copied the error from Whittaker => why he took it wrong?

This depends on the degree of the vector calculus accepted those days -

why "few", isn't this inconsistency trivial?

a typical answer by someone who has characterized themselves as "someone who

has just invented tricks"

this is not to say that the Dyson equation ist not a most powerfull equation

Looking forward to see this on your website :-)

'beautiful' is independent of correct/wrong

But those ideas of 'non-particlecists' are supported by the failures of the
