At this point I should briefly state that,
since my work had been ignored for decades and none of it was in any college
or university course, I abandoned it. Thus, in its place, I needed to learn
Classical Electromagnetism. I began this study by asking “The Catt Question” http://www.ivorcatt.co.uk/cattq.htm
, previously called "The Catt Anomaly", an elementary question
about classical electromagnetic theory. It has nothing to do with any Catt
theories. Nobel Prizewinner
Brian Josephson wrote; "I've just been talking with Catt at the
college's alumni lunch today. He explained that the origin of the 'Catt
anomaly' was in the question of what happens when one charges a capacitor
rapidly. [Wrong. Cattq
is a request for clarification of a TEM wave - IC] It certainly is
the case that there will be a time delay in charging because of the finite
size of the capacitor and it is unfortunate if a paper pointing this out was
not accepted for publication anywhere other than Wireless World (which
incidentally, in the 1950s, published a letter from me on how to reduce
distortion in class D amplifiers). On the other hand, I cannot endorse the rejected
paper unconditionally as I have not seen the detail. Brian J. PS: Ivor
seemed unaware that we had met me before -- Forrest introduced him to me on
an earlier occasion when they were dining in Trinity through Ivor's Cambridge
MA [?]." - Brian Josephson 28/9/08 Forrest Bishop came to Trinity High Table
as the guest of the late Kurt Metzer. Forrest
Bishop and Brian Josephson previously agreed by email to meet at Trinity High
Table, and they dined together. On Brian's request, Forrest pointed out Ivor
Catt's back to Brian. Ivor was sitting at the other long table. Brian did not
then approach Ivor Catt, and they had never met before until last Sunday when
Brian introduced himself to Catt at an "alumni get-together". Brian
then being rather preoccupied, since it was in the middle of a magnificent
buffet lunch, they had a brief meeting, and Brian did not take up Ivor's
suggestion that they meet later that day. The article "Displacement
Current" is at "it is unfortunate if a paper pointing
this out was not accepted for Also see "Charging a
Capacitor" Wireless World had published material by my
team of researchers - Davidson and Walton - for a couple of years. I told the
then editor, the late Tom Ivall, that we also had
"controversial material". He said that they welcomed controversial
material. I replied that I doubted it. After discussion with my two
co-researchers, as a try-on, we boiled down one item of "controversial
material" to a two page article, "Displacement
Current" , which Brian now regrets could only be published in
"Wireless World". What is underlying the article is the new
information that "a capacitor is a transmission line". The
classical treatment of the capacitor has to be compatible with the classical
treatment of the transmission line, which it is not. At Trinity High Table a year or two ago, I
told May Chiao, deputy editor of "Nature Physics", that if she
published an article which contained the information; "A capacitor is a
transmission line," that would be the end of her editorial career -
certainly if the article also mentioned Displacement Current. I told her she
could however publish "A transmission line is a capacitor." Five
minutes later she said; "But a transmission line is a capacitor!" The May Chiao experience has to be
considered alongside the statement by Nobel Prizewinner
Josephson, above; " .... it is unfortunate if a paper pointing this out
was not accepted for She does not reply to my
letters . Also see "Maths and
Physics" , where Josephson shows us the smoking gun; the key factor
in the capture of science by mathematics. Ivor Catt @@@@@@@@@@ Comment by Forrest Bishop. The reason I consider this such an important
paper is twofold. First, the idea of displacement current led to the term in
Ampere's Law that allowed Maxwell to construct his electromagnetic wave
equation(s) and then furthermore, and this is important: supposedly that
enabled Maxwell to unify magnetism, electricity and light, and to predict
radio. This has come down to us as THE premier example of the Power & the
Glory of mathematical physics. Your (CDW) little paper pulls the rug right
out from under that pretension. Forrest Bishop. 30th September 2008 @@@@@@@@@@@@ Comment by Ivor Catt on Forrest's comments. The thread begins with what Heaviside
called "Maxwell's leap of genius" in formulating the concept of
Displacement Current. It was formulated in order to take the capacitor into
the fold fenced by Kirchhoff's
First Law ; "At any point in an electrical circuit that does not
represent a capacitor plate, the sum of currents flowing towards that point
is equal to the sum of currents flowing away from that point." The article "Displacement
Current" investigates Kirchhoff's Law at the point where the input
wire enters a capacitor. To satisfy the Law, Maxwell proposed a
pseudo-current leaving the capacitor plate equal to the input current, so
that the total current entering the point where wire connects to plate became
zero. He overlooked the fact that the input current first spreads out across
the capacitor plate, so that the extra Displacement Current, far from satisfying
Kirchhoff's Law, defies it by making more current leave this point, both
along the plate and across the space between the capacitor plates, than
enters this point down the input wire. Everyone since Maxwell, including
Heaviside, had until it was pointed out a century later in 1978 ,
also failed to notice the oversight. This oversight, since it was pointed
out, has been ignored by lecturers and text book writers. As Forrest notes, the spurious
"Displacement Current" is a field, or wave, in the space between
the capacitor plates. This generated the idea that light was electromagnetic,
because light was also a wave in space. The "Displacement Current" term
is a key term in Maxwell's Equations, which in turn are regarded as perhaps
the high point in the glory of mathematical physics. Feynman says that
Maxwell's Equations will be regarded historically as more important than the
American Civil War, which occurred in the same decade. Thus, as Forrest says,
the article "Displacement Current" has massive
ramifications. Ivor Catt 1st October 2008 . |
