Conversion of Physics Students into Zombies |
Consider Problem 7 ("Seeing behind the stick"), p. 47 (solution on p.
54), in
http://www.courses.fas.harvard.edu/~phys16/Textbook/ch10.pdf
Any normal person, if "able to see a mark on the ruler that is less
than L units from the wall", will also be able to see a pawl released
by the back end of the stick and emerging from the mark so that no part
of the stick can move to the left of the mark anymore. Then the
absurdity implicit in Problem 7 would make the normal person abandon
the respective science (physics) forever.
Through natural selection, a small (ever decreasing) number of students
remain faithful to the respective science (physics) by being able to
see the mark and at the same time being totally unable to see any pawl
emerging from this mark, no matter how minute the observation is.
Abilities and inabilities of this type will allow those students to
become pemanent members of Einstein's cult one day.

This is just a variant of the train problem. The easy solution
is to consider the primed frame as the one that is actually
stationary, then apply the Lorentz transformation. (cf my
previous post.)

[smile] It's not that bad. All you need is someone who understands
Relativity.

I don't think that adherents to Einstein's Theory form a cult. It's
accepted because it works. Most criticism of it comes from the science
fringe, most of whom have not taken graduate physics courses and are
unaware of how Relativity explains things that other theories don't.
Until someone can show where it doesn't work, I don't think that any
scientist will reject Relativity. Every physicist that I know of
(including myself) admits that Relativity *could* break down one day,
but not today, since most critics can not demonstrate how it is wrong.

To Pentcho,
Keep up the good work! But none are so blind as those who do not want to
see!
As for me, I can't bring myself to read the nonsense relativistic textbooks
preach. It makes me sick! So I am glad that you bother to point out their
illogical reasoning for me.
For my part, I will continue to provide the correct explanation for the
various 'relativistic' phenomena mentioned in this newsgroup.
Thanks again,
Len.

Yet experimental evidence is in favour of the "illogical reasoning" og
relativity. Maybe nature does not care what you find illogical?

Yet experimental evidence is in favour of the "illogical
reasoning" og
relativity.
Name one experiment and the experimenter to back up your claim.
Experiments:
1881-1887 = Even though they didn't know it, Michaelson and
Moreley provided the first evidence of length contraction.
1938 = H E Ives and G R Stilwell showed that the relativistic
Doppler shift was correct and the one based on the aether
theory was not.
1941 = B Rossi and D B Hall showed time dilation predicted by
Special Relativity using muons.
1972 = J C Haefele and Richard E Keating showed time dilation
predicted by both Special and General Relativity using
cesium clocks on jet airliners.
1979 = J J Dykla showed that transverse motion generates Doppler
shift just as Special Relativity predicts. Aether theory
predicts no Doppler shift for transverse motion.
1610-1990 = Galileo, Newton, Bessel, Eotvos, Dicke, et al showed
that inertial mass is probably equivalent to gravitational
mass as General Relativity assumes. Most recent value is
by Adelberger (1990) at Abs[mI-mG]/mI < 10^-11.
1919-1973 = Several astronomical observatories including Greenwich,
Lick, Yerkes et al verified the deflection of light due to
mass predicted by General Relativity and not by Newton, using
solar eclipses.
1968-1991 = Several planetary probes have verified the retardation
of light predicted by General Relativity and not by Newton.
Best value was from Viking 2 (1979) on Mars at within 0.1% of
the prediction of General Relativity.
1970-?? = Observatories are continuing to collect evidence for
gravitational lensing predicted by General Relativity. Included
are Q0957+561 A and B, Q2237+031 (Einstein Cross) and many
others.
??-1992 = U S Naval Observatory with others including Arecibo,
Haystack, and Goldstone verified the precession of planetary
orbits predicted by General Relativity and not by Newton.
The observations also showed that Special Relativity is only
an approximation to General Relativity.
Those are just the ones I can list off the top of my head (and my
notes that I can find). Good books on Relativity will have more.

Observation:
http://www.britastro.org/vss/gifc/00918-ck.gif
At
http://www.britastro.org/vss/obj-aql.html
this (Aql V1493) is identified as Nova 1999-1. Novae typically
rebrighten somewhat after their initial phase even if they are
in a cycle, such as part of a binary system. No big deal.
Explanation:
http://www.ebicom.net/~rsf1/sekerin.htm (fig 3)
Not much of one. If he had used Relativity, he could have
cut to the conclusion without all the song-and-dance. That's
one reason physicists prefer Relativity.
His conclusion that it could be a binary certainly is consistent
with both Relativity and observation. So I don't see how Aql V1493
(Nova 1999-1) invalidates Relativity.
