Most of what is taught in high school physics today is stuff discovered
from 400 years ago, as discovered by Isaac Newton. I understand the need
to keep things simple for HS students to digest, and most of the physics
from 400 years ago is still basically the only stuff that we deal with
in everyday life. However, when modern physics is introduced in
university, a lot of students are surprised by how different physics is
at these extreme levels. Many are unable to grasp it and end up becoming
deniers about Quantum Mechanics, and especially Relativity.

With modern computer graphics equipment, it should be easier than ever
to visualize modern physics without going into explicit details about
its complex equations. Maybe it's about time that modern physics is
introduced into high schools, at a basic level, mainly to get them used
to the far out ideas that are beyond our everyday experiences, and
prevent more from becoming deniers? Relativity could be introduced into
the end of physics (mechanics) courses, while Quantum Mechanics could be
introduced into the end of chemistry courses? It shouldn't be a full
curriculum on these subjects, with experiments, etc., just a documentary
just to introduce them to the ideas that are modern physics.

Which makes it a great foundation on which to build further knowledge
and it is still relevant to the rest of the population in daily life.

People still drive too close and fast like they do not believe in basic
Newtonian physics such as momentum and kinetic energy.

Not sure that the physics and chemistry graduates are the problem here.

Most of the deniers study soft subjects or electrical engineering where
relativity must be lamentably taught based on the number of nutters who
still write in to Wireless World (it was much worse in the 1970's).

I disagree. Until you have a basic understanding of classical physics
introducing relativity and quantum mechanics without the mathematics
makes it into another just so story and prone to attack by deniers.

The thing that really needs to be communicated is that at relativistic
speeds common sense Galilean dynamics no longer works reliably.

The same is also true of Galilean dynamics in a rotating reference frame
as gunnery correction tables used by Northern powers in the Southern
hemisphere have demonstrated as recently as the Falklands War.

I could countenance teaching relativity as "the laws of physics are the
same for all observers in an inertial frame". One law is known to be
that electromagnetic radiation always travels in a vacuum at speed c.

Then derive the beautiful derivation of the relativistic transforms
using the mutual events of two metre rules AB and CD passing each other
at a speed v. That gets you the rules of the game with only high school
algebra (although admittedly quite a lot of it)

> http://www.mndaily.com/2012/11/19/physics-double-standard

I recall my own physics A level did include some basic discovery of
radioactivity, charge on an electron and the photoelectric effect for
which Einstein got his Nobel Prize. Nothing after 1920 though. And A
level chemistry did involve a handwaving explanation of tetrahedral SP3
orbitals but without the requisite mathematics to back it up.

All physics should be totally cut from any High School curriculum. And
luckily this goes right with the modern push to eliminate algebra and
geometry as well!

Nobody EVER uses any of this stuff once they graduate. Surveys have been
made and the overwhelming majority affirm they never used it again. What
does a modern citizen need with this kind of information? It's about like
teaching slaves to read and write. It can only end badly.

And while "modern" physics is even worse, having no utility even for
those employed in the field, It does have the advantage of training
students to blindly accept pronouncements and dogma from those in
authority without question. And obviously that is good.

Please tell me more about this. It is hard for me to conceive that
British forces defeated by German ships of of Coronel, and later
defeating German Forces at Falkland (WWI) would be unaware of Coriolis
forces. Naval gunfire in WWII in the Southern hemisphere also would have
been noticed.

I have noticed, in my career, that many engineers who took up
engineering as a good way of making a living rather than as an
interesting profession may have been insulated from real life situations.

That's already over.
There are no good physics teachers left for the smaller kids.
The (female) physics teacher at Feldkirchen, Austria,
would teach the littluns that iron (Ferrum) does not conduct
electricity. Too bad, if any of the kids had taken her teaching
seriously and tried to connect an iron wire to the mains plug.

It's better to have no physics than wrong physics.

They were not unaware of it. They were applying the correction with the
wrong handedness in the Southern hemisphere and so *doubling* the error!

http://encycl.opentopia.com/term/Battle_of_the_Falkland_Islands

The gunnery control software allegedly also had to be tweaked as a
matter of urgency in the second Falkland War against Argentina too. And
inbound French planes and Exocet missiles added to the hostiles list.

My A level physics teacher was a woman (inherited from the girls school
that combined to make a secondary school and sixth form college). She
was very good as was the head of maths and her understudy also women.
Back then women physics graduates were rarer than hens teeth.

Depends how wrong it is. Most physics as taught at school is slightly
wrong or at the very least a crude approximation to the real world.

xxein: I can agree with all that. But I wonder what physics will be
like 400 years from now.

I'm very sure the physic will not change, but our understanding of it
will.

What next? Pondering over whether to teach Relativity and Quantum
Mechanics to a two year-old 400 years from now?

We did work on special relativity in high school. This was 46
years ago. I have no idea what they do nowadays. You can't do much

Non-linear differential equations aren't high school. Same thing with
quantum mechanics. The math prevents more than a descriptive approach,
but you can introduce concepts.

Sam, as you have pointed out here many times, observation and experiment
has nothing to do with science. It's all about a democratic majority vote
and a "consensus". If enough national science foundations and agaencies
and science trade organizations agree on something (example AGW) then
clearly it is automatically true.

What physics courses did you take?

Ha! You imply that Einstein's science fiction, 'counterintuitive',
'far out ideas' are equivalent to 'observation and experiment'
They are not - they are false interpretations of observation
and experiment, which have possible theoretical interpretations
different from Einstein's science fiction spacetime.

I don't know how anyone can "still write to Wireless World" as no
magazine of that title has existed since 1984.

I do recall the excellent series of articles in that magazine by the
distinguished physicist Dr Scott Murray called "A heretics guide to
physics" where he demonstrates how physics has slid into the realm of
mysticism.

But the speed of light is only about 1ft per nanosecond. Feet and
nanoseconds are both everyday unit in this century. What is missing is
any explanation of why dimensions change other than because the maths
demand it to make the second postulate true.

Beckmann and Mandics pointed out the possibility that Lorentz transforms
could simply be equivalence formula, making up for inaccurate
electrodynamics by suitable deforming space and time to achieve the
correct result. Thus cries of "relativity works" in no way proves that
it is correctly based.

Essen makes the same point a different way:

"Science involves measurement and measurement requires a system of units
which need to be carefully chosen such that do not have duplication.
Consider now the simplest of all measurements, the measurement of
velocity v expressed as the distance d travelled in time t. The result
is expressed as v=d/t. It is possible to define units in any two of the
quantities in this expression. In practice the units of distance and
time are defined and velocity is measured in terms of those units. If
the unit of velocity were defined as well then the value v can be
expressed in two ways in terms of the unit of velocity and in terms of
units of length and time. Conflicting results could be obtained.
Only a unit of measurement can be made constant by definition.
Making the velocity of light have a constant value c even to observers
in relative motion is comparable to making a unit of measurement
duplicating the units already defined. The definition of the unit of
length or that of time must be abandoned. To meet Einstein's two
conditions it is convenient to abandon both.
The contraction of length and the dilation of time can now
be understood as representing the changes that have to be made
to make the results of measurement consistent. There is no
question here of a physical theory but simply of a new system
of units in which c is constant, and length and time do not
have constant units but have units that vary with v^2/c^2. Thus
they are no longer independent, and space and time are
intermixed by definition and not as a result of some peculiar
property of nature.... If the theory of relativity is regarded
simply as a new system of units it can be made consistent but
it serves no useful purpose" Essen

Try it. Assume I am a student. Assume you and me are in relative

runs slow. I will hold a similar view. Whose view is correct?
So natural question is whose clock is running slow? Or nobody’s?

So, get together and see who is REALLY smaller.
Get together, or get at rest w.r.t, each other, and see who has aged

With a pathetically outdated and willfully overloaded national energy

When Richard Feynman was still alive, he was the technical consultant
for a NOVA program about time. His presentation of a Fabry-Perot clock
clearly showed that light had to travel a longer distance in the moving
clock in a second than for a stationary clock. The ONLY mathematics
required is the Pythagorean theorem for right triangles. This clock
consists of two mirrors facing each other with a pulse of light bouncing
between them. The axis of the clock is normal to its direction of
motion. Because of this extra distance, the moving clock "ticks" more
slowly than a stationary clock.

To add to Feynman's presentation, add a moving Fabry-Perot clock with
its axis ALONG the direction of motion. For the two moving clocks
(perpendicular and parallel to the direction of motion) to tick at the
same rate, the spacing between the mirrors of the parallel clock must be
reduced. This can only be done if the moving unit of length in the
direction of motion to shrink. The physics drives the math--not the
other way around.

When I went to school, the speed on the hypotenuse of a right triangle
was sqrt(c^2 +v^2), not sqrt(c^2+v^2) = c.
Increase the speed v until it equals c and we then have sqrt(c^2+c^2)
= sqrt(2c^2) = 1.414 c, and that isn't c either.
The math for your (or Feynman's if indeed it was he that made it) impossible
claim does not exist.
Moreover, the Michelson-Morley experiment clearly shows no change
in time.
Why did Einstein say
the speed of light from A to B is c-v,
the speed of light from B to A is c+v,
the "time" each way is the same?

We'll add to that:
Why was Feynman stupid enough to believe it?

Proper time does not change in SR. But that is not the relief. What we
now have are two measurements for a single clock. Improper and proper
one. Since proper ticking of clock remains unchanged it should be
clear that improper measurements carry no meaning. They are clearly
apparent and wrong.
I don’t know about gas but there is no reason why SR is not
applicable. I have forgotten chemistry.
After referring a book I have a rough figure for the velocity of gas
molecules. It is too low, about 483 m/sec. at 300 K. So mass of gas
molecules will increase by a factor of 13^-13. What is the weight of
the gas? It is negligible and so relativistic effect is not
measurable.

"Lord Androcles, Zeroth Earl of Medway"
Feynman was not stupid. Misapprehension is in the head of some
"stationary" observers. For a Fabry-Perot clock of length L mounted
transversely to the motion, the mirror moves a certain amount D in the
time required for the light from one mirror to reach the other. Thus,
the distance traveled by the light pulse is sqrt(L^2 + D^2). That is
greater than L. Thus the moving clock runs slower although it does not
look that way to anyone riding along with the clock. In a stationary
clock, the distance the light has to travel is only L.

Think your "the speed of light from A to B is c-v, the speed of light
from B to A is c+v" carefully again. The light pulse always travels at
c, but the distance it travels from A to B is not equal to the distance
from B to A. Einstein also was not stupid.

First of all, I know what a Fabry-Perot interferometer is, but I've never
heard of a Fabry-Perot clock. The Fabry-Perot interferometer, as far as I
can see, has nothing to do with Einstein's light clock. I mean, yeah,
light reflects off two surfaces in both devices, but using a PF
Interferometer is just an unnecessary complication.

Wormly almost never posts his own original work so I tried to google from
where sam plagerized his post to see what the context was, but google
came up with nothing. It may be Wormley's original work! .Which would
explain the fuck up...

I think what is being talked about is Einstein's light clock, and not a FP
interferometer.

The whole Einstein's light clock thing is nothing more than a hypothesis
based on the premise that the speed of light is constant in all inertial
frames. It is not an experiment because no one has been able to
accelerate a light clock to relativistic speeds.

It's not about remembering the chemistry really. I just wanted to
expand the count of relatively moving reference frames. For the sake
of teaching me the great insight of time as measured by stationary and
moving manmade clocks, pretend the gas molecules have speeds in which
relativistic effect is significant. It's just a thought experiment.

Going back into reading mode where the self proclaimed experts pretend
to have won a scientific argument only by denigrating their opponents.
It's as if the Laws of Physics don't apply to the stupid ones. No
wonder no one signs up for Physics at any level of schooling. Sheldon
Cooper, of The Big Bang Theory, portrays the condescension that
worthless ill-qualified Reseachers and Teachers have resorted to. Per
the denigration, their arguments -- actually lack of -- simultaneously
become canonically worthless, in my personal moving frame of
reference.

It cannot be. If velocity of light is c in the moving compartment then
light velocity is source dependent and so more than c in the moving

Obviously the FP thing is just a way for Feynman to make a point. But you
just don't get around science enough Marvin. Never heard of a laser, I
take it? Never heard of any of the modern "atomic" clocks? Maybe after
you get an education...

But the interesting and important thing, is that the "light clocks" are
just a portion of a variety of "electromagnetic" clocks. Yes they are all
thought experiments, but they CAN be calculated by physics. And what is
interesting is that while MANY electromagnetic clocks behave in
Einsteinian fashion...NOT ALL DO! This is an important result, because
in science just ONE exception kills the ENTIRE theory. I won't tell you
who did this or where to find these calculations because no doubt all the
"strategic writers" would be activated using their anti-Tesla methods on
one more scientist. Screw HVAC and the donkey he rode in on. It's just
enough to know that these calculations exist.

Even more interesting, is that the slowing of electromagnetic clocks in
no way implies the slowing of biological clocks which is always
idiotically assumed!

As for you, study more physics.

It would be helpful if you actually said what you think a Fabry-Perot
clock is. As I said, I have studied the physics of a Fabry-Perot
INTERFEROMETER, but not a "clock". I am also familiar with Einstein's
"Light Clock" and the description of how the light clock demonstrates
time dilation and length contraction.

Atomic clock have nothing to do with relativistic effects. Not sure why
you're throwing lasers and atomic clocks into the discussion.

Sorry won't happen again. Don't have the time to waste. I'll need it to
study more physics and the non-relationship between atomic clocks and
relativistic effects.

Anyway, I never enter the "who is smarter than Einstein" contest here
online. Hence, I try to never discuss relativistic effects. Obviously, I

I had no idea you were an anti-SR crank.

True enough that no one has ever conducted an experiment to show length
contraction like they've validated time dilation, but given Maxwell's
equations, length contracts.

There was an experiment where they compared an atomic clock in a fast
moving airplane in flight with an atomic clock on the ground, to test
time dilation. They verified time dilation.

Are you under the misconception that the physics of the atomic clock is
based on special relativity? Good heavens no!

GIVEN the experimental results of the Michelson Morley experiment and
other duplicating efforts that found that the speed of light did not
change in a local inertial frame regardless of the speed, the direct
conclusion via the "Einstein's Time Clock" experiment is time dilation
and length contraction.

This conclusion is consistent with and can be reached by the
transformation between moving frames that holds Maxwell's equations
invariant. If you're going to reject SR, you reject Maxwell's equations
as well.

Nature doesn't care about my equations, true enough, but I care to make
my equations describe nature while the crank doesn't care about nature.

I've not heard a better explanation for the measured speed of light being
the same in all inertial frames.

Actually, the airplane experiment was to test GR and the slowing of time
in a gravitational well, and not a test SR. BenJ got me off track when he
brought up atomic clocks which has nothing to do with the subject. My
bad. I was trying to figure out why he even brought up atomic clocks.

An interesting argument for being closed minded and not listening, but it

As I keep pointing out the reason it is accepted is because the
philosophy underpinning physics is not interested in reality. It says
reality is beyond the human mind and allows them to advance any "theory"
without deference to physical discipline.

It is that philosophy which should be challenged rather than the
"nonsense" which it accepts. It is only nonsense in terms of a
"sensible" philosophy. A sensible philosophy says a cat cannot be both
alive and dead. That the most stable particle in the universe - the
electron - must have a precise position even though it is impossible to
determine where it is. Retrospectively we can determine how long the cat
has been dead and where the electron *was* but the new philosophy, which
replaces understanding with prediction, says retrospective measurement
is irrelevant as it does not aid prediction. It says as we cannot
observe an electron in transit we cannot assume it exists as a particle
- that we create it when we measure it - even that there are an infinite
number of parallel universes and that it only arrives where it does in
ours.

"An electron can be observed only when it interacts with matter or
radiation: therefore it is of no concern to physics while it is in empty
space". Dirac,

How can one argue with people who accept this stuff and pat themselves
on the back for being able to accept this stuff and sneer at people who
don't accept this stuff.

What worries me is that eventually the public perception of physics will
become "very clever - but absolute twaddle". It is all very well to say
"serves them right" but the public will not be discerning about which
bits of physics are twaddle and may even turn against science generally.

the dull and the ignorant; they too have their story.
Avoid loud and aggressive persons, they are vexatious to the spirit. If you
compare yourself with others, you may become vain or bitter; for always
there will be greater and lesser persons than yourself.
Enjoy your achievements as well as your plans. Keep interested in your own
career, however humble; it is a real possession in the changing fortunes of
time.
Exercise caution in your business affairs; for the world is full of
trickery. But let this not blind you to what virtue there is; many persons
strive for high ideals; and everywhere life is full of heroism.
Be yourself. Especially, do not feign affection. Neither be cynical about
love; for in the face of all aridity and disenchantment it is as perennial
as the grass.
Take kindly the counsel of the years, gracefully surrendering the things of
youth. Nurture strength of spirit to shield you in sudden misfortune. But do
not distress yourself with dark imaginings. Many fears are born of fatigue
and loneliness.
Beyond a wholesome discipline, be gentle with yourself. You are a child of
the universe, no less than the trees and the stars; you have a right to be
here.
And whether or not it is clear to you, no doubt the universe is unfolding as
it should. Therefore be at peace with God, whatever you conceive Him to be,
and whatever your labors and aspirations, in the noisy confusion of life
keep peace with your soul. With all its shams, drudgery, and broken dreams,
it is still a beautiful world. Be cheerful. Strive to be happy. -- Max

You say that your equations describe nature. But equations never
describe nature, they assume nature.
It is one thing to say that a particular experiment proves that c is
same in all frames and quite other to examine logic behind it.
In Hafele Keating experiment, both GR and SR effects are considered.
One of the critical site is,
http://thescientificworldview.blogspot.in/2011/02/time-dilation-and-hafele-and-keating.html

One can find little bit sense in what Lorentz said. He did not say

ether. So far as MMX is concerned, one conclusion could be that light
is ballistic.

We're moving along at near the speed of light as is, and supposedly
everything else is strictly moving away from us in every possible
direction. So, how can SR be objectively applied from any given point
of reference?

Relativity is at the end of modern college text books (and introduced in some high school texts). The problem is that a lot of our TEACHERS aren't interested. I got into a very heated exchange with my college professor over relativity. Essentially, she said it was "boring" and just a "repeat of subjects we covered with new equations", to which I stood on my desk, looked at the classroom, and stated that according to relativity, I am now aging slightly slower due to the fact that I am moving slightly faster than them.

The point was lost on my professor - we did an extra week of LRC circuits instead. :P

Modern physics should be introduced early. It's exciting, it's fresh, and most of all, it's relevant!

That is simply not so. One can do an experiment to find the position of a
mass falling in a gravitational field and describe its motion with

x = 1/2*g*t^2

There is no assumption made. The data is taken and an equation found to
describe the data.

Interesting website - many words but no content. I'd have to say, "not

Equations never describe nature because they cannot. For example
vector analysis was applied to describe hydrodynamics and assuming
similarity in ether, Maxwell applied these to electromagnetic fields.
However what you said is not wrong. I should have said, equations do
not describe basic concepts.

After reading the many comments in the thread, I would think it
useful, if for no other reason than to encourage inquiring minds to
learn more, to introduce high school students to some topics in
special relativity, such as the Lorentz transform, time dilation
and length contraction "observed" in cosmic muons and mass increase
experienced in ring particle accelerators... with emphasis on the
fact that the observations are observer dependent and real!

SR does not deal with reality. Predictions of SR results are purely

Tell that to the designers of circular particle accelerators that
wouldn't work if mass increase isn't taken into account.

That that to the cosmic muon that make it to the detectors on the
ground.

Tell that to the atomic clocks that "lost time" going around the
world.

You have failed to understand what Maxwell's equations were
indicating--that the speed of light is the same for all observers.

Though I am not a mathematician, I always loved it. To know the
difference between equations and concepts read “World of mathematics”

That was a fun book to read when I was a kid, as was George
Gamow's "One Two Three . . . Infinity".

Have you read Einstein's 1905 paper, "On the Electrodynamics
of Moving Bodies", and followed the mathematics?

Most colleges and universities have physics labs facilitating the
student learning physics for measuring physical phenomena. Even in
high schools.

Have you ever measured the speed of light?

Student understanding of time in special relativity: simultaneity and
reference frames
> http://arxiv.org/pdf/physics/0207109.pdf

This article reports on an investigation of student understanding of the
concept of time in special relativity. A series of research tasks are
discussed that illustrate, step-by-step, how student reasoning of
fundamental concepts of relativity was probed. The results indicate that
after standard instruction students at all academic levels have serious
difficulties with the relativity of simultaneity and with the role of
observers in inertial reference frames. Evidence is presented that
suggests many students construct a conceptual framework in which the
ideas of absolute simultaneity and the relativity of simultaneity
harmoniously co-exist.
