Five "priceless gems" published by Citrus Press (Titusville, Florida)
Three science books by John Granville
Discovery of Motion (2007) John Granville
subtitled: An Introduction to Natural Philosophy (533 pages)
science
lover's "must have"
https://www.amazon.com/Discovery-Motion-Introduction-Natural-Philosophy/dp/1934242985/
https://www.bookfinder.com/search/?author=Granville&title=discovery+of+motion&lang=en
A perfect gift for any teenagers with an interest in science (but science nerds will want a copy for themselves)
- This book is sub-titled An Introduction to Natural Philosophy for good reason. The author begins by taking
the reader from a speculative "natural philosophy" of a caveman to the actual "natural philosophy" of the early Greeks. He
continues through the European Dark Ages bringing the reader to the present day where we use the word science
rather than natural philosophy. If you have never been previously exposed to complete explanations for
concepts like Zeno's Paradox then you will be in for a treat.
- I had read Zeno's Paradox more than a half-dozen times in other books, but those presentations now appear incomplete
because I never got the point. In later chapters Granville employs Zeno to support the idea of limits (the
on-ramp to calculus; don't worry, the math stays simple)
- Your inner-nerd will soar while you read about Granville's modern experiment which repeats Galileo's work at Pisa
(Granville only uses material which would have been available to Galileo with one notable exception: latex party balloons
and paperclips)
Comments:
- Richard Feynman once said "really good books were meant to be read twice". I feel that Discovery of Motion
is such a book.
- I have often lamented the passing of great explainers like Isaac Asimov and Carl Sagan while wondering "where
are their replacements?" John Granville is one such candidate and I find his writing style the correct mix of "meat and
potatoes". Like Asimov, Granville includes a lot of supporting material and is not shy about publishing mathematical equations
which you can skip if you desire, but I suggest you do not.
Æther Drift (2015) John Granville (84 pages)
(a.k.a. Ether Drift)
for serious consideration by all nerds
https://www.amazon.com/Aether-Drift-John-Granville/dp/1934242969/
comment: If you want to be intellectually stimulated for the tiny sum of $10 then buy this book. The only
descriptive phrase which comes to mind is "very high signal-to-noise ratio". The "dialog" between Simplicio and JG are reminiscent
of another great author
Nature hides her secrets in plain view (from the back cover)
This book is about a modern attempt to measure an æther drift. The tests were conducted between 2010 and 2013, but the
preparatory work goes back to much farther than that. Your might not find it extraordinary that someone would repeat a classic
old experiment, but you might well find the underlying reasons more than interesting ... and the results even astonishing.
In 1881, from April to August, A.A. Michelson conducted experiments to measure an æther drift relative to earth's motion in its
orbit about the sun. To virtually everyone's amazement he found no first order drift. The existence of an aether was thought to
be imperative to conduct light waves, and Michelson's results were simply beyond comprehension. There were other experiments, of
course, all yielding the same results.
G.F. FitzGerald and H.A. Lorentz developed a theory that objects "shrank" when moving through the aether, but the explanation
finally accepted (i.e. Einstein's Relativity theory) postulated the speed of light was the same regardless of the motion of any
reference coordinates. Maintaining the principle of relative motion required time and space to become variables, and the classic
function of an aether became incompatible ... and the aether was pronounced obsolete.
Be-that-as-it-may, this book reports an experiment that leaves little doubt an aether exists. Most astonishingly the theory is
neither beyond comprehension nor even obscure. In fact it's obvious! ... and pretty nearly imperative. For more than a century
this aether has been right before our eyes ... hidden in plain view. The thing we've all been missing is revealed in the
Preface, and PART II of the book fills in the details.
Chapters:
- PART I - THE EXPERIMENT
- The Granville Interferometer 1
- Theoretical Expectations
- Data & Data Reduction
- Test Results
- PART II - THE ÆTHER (or Aether, or Luminiferous Ether)
- Æther
- Photons 2
- Scientific Method I
- Scientific Method II
Subscripts:
- In order to repeat the Michelson-Morley experiment
they built their own interferometer employing modern electronics:
- an inexpensive Helium-Neon laser
- a photo diode detector
- a piezoelectric transducer behind one of the mirrors (modulated to minutely cycle the length of one light path)
- a stepper motor to slowly rotate the platform
- comment: my primary college education was as an Electronic Technologist so I found this part of the
book "delightful"
- partial quote from page-51: Photons are electromagnetic waves as they occur at visible (i.e. light)
wavelengths ...
{ skip a paragraph on antenna-length math from every RF engineer's handbook }
At the frequencies of light (~5x1014 Hz) antennas shrink, of practical necessity, to atomic
dimensions
{ more stuff is skipped over }
... the vibrating electron is a microscopic alternating current confined to atomic dimensions (i.e. the atom
acts like an antenna) and the electromagnetic waves are generated according to Maxwell's
equations.
Comments:
- so the colloquial definition of photon could be redefined to mean "a packet of EM energy whose wavelength is
less than the size of an atom"
- therefore, EM transmissions (Radio, TV, Wi-Fi) which employ a wavelength longer than that found in visible light, do not
involve photons, per se (but perhaps this is a forest-versus-trees thing)
- therefore, as soon as we use the word photon we are restricting the conversation to quantum mechanics (so the photon is
only a quantum particle)
- Einstein's 1905 paper on the photoelectric effect
mentions photons only because Einstein is dealing with quantum mechanical effects (discrete packets of energy waves; would
it be wrong to think wavicles?)
- Food-for-thought:
- consider a ray of light moving through plain glass; forget about photons as waves for a moment and only think about them
as particles; are they traveling between the atoms (captured then re-emitted) or is something else occurring?
- now consider a kilometer of inexpensive multi-mode
optical fiber. Here the word "mode" to means "path" and these can be of different
length (one path is straight down the middle while the longest path bounces off the reflective inside surface when the fiber
is bent, curved or coiled). The signal is transmitted as a single digital pulse (square wave) but is received as a smeared
out sign wave)
- now consider a kilometer of more expensive single-mode
optical fiber where light never reaches the inside surface but is gently
guided back to the middle due to a change in the incidence of
refraction. One might suppose that the photons are moving between the atoms (captured then re-emitted), but a better
theory (put forth in this book) is that atoms behave as antennas and the photons are guided along with almost zero loss
Concerning the Discovery of the Æther (2016) John Granville (64 pages)
for serious consideration by all nerds
https://www.amazon.com/Concerning-Discovery-AEther-John-Granville/dp/193424290X/
This
small book is dense with well written content supporting the author's hypothesis that the
luminiferous
aether is real. The author takes us on a brief excursion through European natural philosophy with stops at Descartes, Huygens,
and Maxwell who also believed aether was real. The journey continues through Michelson and Morley, who's famous failed experiment
proved that aether was not real (or at least could not be detected).
Chapters:
- The Æther Sea (or "Ether Sea")
- Gradient, Divergence & Curl (or Grad, Div and Curl)
- The Æther Mechanism (or "Ether Mechanism")
- Electrostatics
- Electromagnetism
- Inductance
- Electromagnetic Waves
- Matter & Mass?
Comment: many people today throw around phrases like "space-time", "vacuum energy", "zero-point energy",
"virtual particles", and "multiverse" never worrying about being labeled "crazy". By comparison, "a real ether" seems to be the
least weird idea of all.
Two FFT books by Anders Zonst
Understanding the FFT (1995/2000) Anders E. Zonst
Subtitled "A Tutorial on the Algorithm & Software for Laymen, Students, Technicians & Working
Engineers"
highly recommended for engineers
(both software and electronic), hackers and nerds
- Subtitled "A Tutorial on the Algorithm & Software for Laymen, Students, Technicians & Working Engineers",
weighs in at 180 pages. I wish I would have owned a copy of this book ten years earlier because I would have saved considerable
time and money.
- quote from page 2: "for now we may say that this transform, in its discrete form, provides a
mathematical tool of such power and scope that it can hardly be exceeded by any other development of applied
mathematics in the twentieth century"
- four chapters on DFT (Discreet Fourier Transform)
- six chapters on FFT (Fast Fourier Transform)
- ten appendices
- demo programs written in PC-BASIC (a generic term for: MS-BASIC, GW-BASIC, BASICA, QuickBASIC, QBasic, etc.) are sprinkled
throughout
- see next book description for demonstration software
Understanding FFT Applications (1997/2004) Anders E. Zonst
Subtitled "A Tutorial for Laymen, Students, Technicians, & Working Engineers"
highly recommended for engineers
(both software and electronic), hackers and nerds
- This first edition of this book (1997) is subtitled "A Tutorial for Laymen, Students, Technicians, & Working Engineers",
weighs in at 415 pages.
- This second edition of this book (2004) is subtitled "A Tutorial for Students, Technicians, & Working Engineers",
weighs in at 278 pages, and comes with a CD-ROM
- Demonstration software: Both books contain example programs
written in BASIC so that Fourier concepts can be more easily demonstrated to the student
Comment: I recently heard the following rumor about these two books: "someone had scanned them into PDFs then
were selling copies online for $10". This might be one reason why you can buy these books for less than $10 each online when the
back cover shows $29.95 and 34.95 respectively. Citrus Press (of Titusville, Florida) is owned an operated by a small group of
retired NASA engineers. Please help support them by
purchasing legal copies from Citrus Press and/or Amazon
