Dimensions Inbetween

"Yet I exist in the hope that these memoirs, in some manner, I know not how, may find their way to the minds of humanity in Some Dimensionality, and may stir up a race of rebels who shall refuse to be confined to limited Dimensionality." from Flatland, by E. A. Abbott -  Flat Land: A Romance of Many Dimensions

See: Analysis and Assessment of Gateway Process

There has been a lot of talk over the years about extra dimensions. It has never been totally clear to me how to define that rigorously and effectively. A matter dominated world,  it becomes scientifically accredited when it is repeated, or,  it has been falsified.

   

The concept of dimension is not restricted to physical objects. High-dimensional spaces occur in mathematics and the sciences for many reasons, frequently as configuration spaces such as in Lagrangian or Hamiltonian mechanics; these are abstract spaces, independent of the physical space we live in.

The thinking here in regards to the scientific explanation, is that in place of space-time, consciousness becomes capable. The brain,  in context of this article,  is functioning with regards to how consciousness amplifies it's use of energy?

The surface of a marble table is spread out in front of me. I can get from any one point on this table to any other point by passing continuously from one point to a "neighboring" one, and repeating this process a (large) number of times, or, in other words, by going from point to point without executing "jumps." I am sure the reader will appreciate with sufficient clearness what I mean here by "neighbouring" and by "jumps" (if he is not too pedantic). We express this property of the surface by describing the latter as a continuum. http://www.bartleby.com/173/24.html

The Question Regarding the Nature of Time

Discussions of the nature of time, and of various issues related to time, have always featured prominently in philosophy, but they have been especially important since the beginning of the 20th Century. This article contains a brief overview of some of the main topics in the philosophy of time — Fatalism; Reductionism and Platonism with respect to time; the topology of time; McTaggart's arguments; The A Theory and The B Theory; Presentism, Eternalism, and The Growing Universe Theory; time travel; and the 3D/4D controversy — together with some suggestions for further reading on each topic, and a bibliography. Time Markosian, Ned, "Time", The Stanford Encyclopedia of Philosophy (Spring 2014 Edition), Edward N. Zalta (ed.), URL = .

If we believe time to be in relation to space-time, then the parameters of our thinking have a distinction about how we look at time?

Time is often referred to as the fourth dimension, along with the spatial dimensions. Time

So you see, one is being selective about the parameters they give them self with which to regard time.

Investigations of a single continuum called spacetime bring questions about space into questions about time, questions that have their roots in the works of early students of natural philosophy. Time

If we are part and parcel, then what said that any idea of continuity can express itself. One would have to believe there is a perfect symmetry in existence that is expressed as an asymmetric example of such perfection, and maybe defined as the matters?

Immanuel Kant, in the Critique of Pure Reason, described time as an a priori intuition that allows us (together with the other a priori intuition, space) to comprehend sense experience.[60] With Kant, neither space nor time are conceived as substances, but rather both are elements of a systematic mental framework that necessarily structures the experiences of any rational agent, or observing subject. Kant thought of time as a fundamental part of an abstract conceptual framework, together with space and number, within which we sequence events, quantify their duration, and compare the motions of objects. In this view, time does not refer to any kind of entity that "flows," that objects "move through," or that is a "container" for events. Spatial measurements are used to quantify the extent of and distances between objects, and temporal measurements are used to quantify the durations of and between events. Time was designated by Kant as the purest possible schema of a pure concept or category. Time

All bold added for emphasis by me.

So, we may come to believe something about yourself that was not quite evident before until we acquiescent to the question regarding the nature of time as we have come to know them.

 If you come to believe there are limits in terms of the reductionist efforts regarding measure, so as to be limited in our perceptions, then what lies beyond, that what we may measure? Do you know how to measure a thought?

 But perhaps most significant is that all their observations are compatible with relativity. At no point does the time machine-simulator lead to grandfather-type paradoxes, regardless of the tricks it plays with causality. That’s just as Deutsch predicted. See: The Quantum Experiment That Simulates A Time Machine

How would you perceive Time Dilation. How would you then perceive Time Travel. How would you perceive time variable measure? Given the constraints of such a measure, we have come "to believe" something in science.

A Message from your Future Self.

I know if you are a scientist this does not equate to anything of value that can be assigned by any measure. So lets be clear here. So,  other then to say,  that any move toward identifying this aspect of self, it is always present and available to our observing, as a process of introspection. If you are going to say that such time travel does not exist in that forward sense, how would/could we really know?

So while there is not much given to the attribution of any real science here, I thought,  if given to such wondering of my mind, then what would happen to the arrow of time(well nothing since there is no real science)? How would this run in contradiction too, what science has to say about it? So if your a scientist how if possible could this ever be true?

The ability of our perception to see in advance would be to have our perceptions run backward in time and to see that this Future self, has an ability to see all that forgoes in the movement forward as to the soul's progressions. Show what it will become,  if it has the ability to see backward in time and to have the ability of to move forward in time.

The elusiveness of this perception of seeing,  from another perspective is intriguing to me.  This wondering is providing some background as to where and how we can recognize that future self.  What wisdom shall flow through back to this time in my life with which to provide incentive. Which is to provide meaning and to understand what I have become,  in that future time. Here in then lies attributes of the forgetfulness as too, what any future self shall see if each segment of the time/space allotted holds "a blanket over" each space time.

I have always argued that this ability of wisdom to be in all of us, then,  takes on new meaning here as I explore the nature and thoughts about this Future self. The Future self then,  is the Higher self. While I had attributed this to the archetypes with which we create, then how does our ability of mind to use metaphorical and subjective symbols too,  "send a message" to our now.

Movie Time Travel DEBUNKED

Will Quantum Gravity Get Us to the Stars?

The Foundational Questions Institute (FQXi) 2nd International Conference in Ponta Delgada, Azores. July 7-12, 2009. Topics include cosmology, astrophysics, gravity, quantum gravity, quantum theory, and high-energy physics. http://www.fqxi.org/

The Meduso-Anthropic Principle is a speculative theory by Louis Crane (1994). The theory develops Cosmological natural selection by leading cosmologist, Lee Smolin and suggests the development of the universe is similar to the development of Corals and Jellyfish. The Medusa generations alternate with Polyp generations. Similarly it is suggested, the Universe develops Intelligent life and Intelligent life produces new Baby universes. Our universe may also exist as a Black hole in a Parallel universe. Extraterrestrial life there may have created that black hole.

Bringing the Heavens down to Earth

If mini black holes can be produced in high-energy particle interactions, they may first be observed in high-energy cosmic-ray neutrino interactions in the atmosphere. Jonathan Feng of the University of California at Irvine and MIT, and Alfred Shapere of the University of Kentucky have calculated that the Auger cosmic-ray observatory, which will combine a 6000 km2 extended air-shower array backed up by fluorescence detectors trained on the sky, could record tens to hundreds of showers from black holes before the LHC turns on in 2007......Thus, hypothetically, the energy required to produce black holes is well within the range of the LHC, making it a "black-hole factory". As Stephen Hawking has taught us, these mini black holes would be extremely hot little objects that would dissipate all their energy very rapidly by emitting radiation and particles before they wink out of existence. The properties of the Hawking radiation could tell us about the properties of the extra spatial dimensions, although there are still uncertainties in the theory at this stage. See: here

 

We have been assured black hole production can be quite safe so we can deal with the idea  that such production quickly dissipates on the level with which we would and can make them?:)  So the level at which such an idea is presented would of course be as suggested as to say that this universe in all it's ability is at the level with which we can make black-holes useful?  Black holes of sufficient size.:) I find that really interesting,  just because we are here.

Getting Perspective on Time

Time has no independent existence apart from the order of events by which we measure it. — Albert Einstein

Currently with the new book written by Lee Smolin about Time, to me, it is a fundamental question about what arises, and,  on how we use time to measure. Also for me,  to ask what relevance time means,  as an emergent product for any beginning.

LEE SMOLIN- Physicist, Perimeter Institute; Author, The Trouble With Physics

Thinking In Time Versus Thinking Outside Of Time

One very old and pervasive habit of thought is to imagine that the true answer to whatever question we are wondering about lies out there in some eternal domain of "timeless truths." The aim of re-search is then to "discover" the answer or solution in that already existing timeless domain. For example, physicists often speak as if the final theory of everything already exists in a vast timeless Platonic space of mathematical objects. This is thinking outside of time. See: WHAT SCIENTIFIC CONCEPT WOULD IMPROVE EVERYBODY'S COGNITIVE TOOLKIT?

 A "scientific concept" may come from philosophy, logic, economics, jurisprudence, or other analytic enterprises, as long as it is a rigorous conceptual tool that may be summed up succinctly (or "in a phrase") but has broad application to understanding the world.

What ignited this question for me goes to a comment I wrote as to what I saw as a precursor to this question for Lee Smolin and others. Further to this, the lessons and explanation Sean Carroll gave toward how we look at time.

Darwinian evolutionary biology is the prototype for thinking in time because at its heart is the realization that natural processes developing in time can lead to the creation of genuinely novel structures. Even novel laws can emerge when the structures to which they apply come to exist. Evolutionary dynamics has no need of abstract and vast spaces like all the possible viable animals, DNA sequences, sets of proteins, or biological laws. Exaptations are too unpredictable and too dependent on the whole suite of living creatures to be analyzed and coded into properties of DNA sequences. Better, as Stuart Kauffman proposes, to think of evolutionary dynamics as the exploration, in time, by the biosphere, of the adjacent possible. See: Thinking In Time Versus Thinking Outside Of Time

While we then become cognoscente of the rules around which parameters have meaning in relation to Time, it was also important to understand that the idea of cross pollination of the sciences recognizes what is brought to the table.

"It is very good that Stu Kauffman and Lee are making this serious attempt to save a notion of time, since I think the issue of timelessness is central to the unification of general relativity with quantum mechanics. The notion of time capsules is still certainly only a conjecture. However, as Lee admits, it has proven very hard to show that the idea is definitely wrong. Moreover, the history of physics has shown that it is often worth taking disconcerting ideas seriously, and I think timelessness is such a one. At the moment, I do not find Lee and Stu's arguments for time threaten my position too strongly."- Julian Barbour

In regard to The Adjacent Possible I was well aware of the implication and parameters  around such thinking to realize that even while applying the trade,  Stuart, was traveling new ground. His thinking is encouraging the flexibility that I am talking about with regard the restrictions one places on them self. I encourage this kind of thinking so as to bolster the lull in scientific advancement to stimulate and foster the idealization of creativity that I think has become stagnate while  moving from one point in the measure to the next. Why Murray Gell-Mann's  move and his expertise is understood in context of new approaches. Simplicity and complexity.

Intent in the Actualized

 Remembering

Return to Home,
Safety seeking,
In my mind,
Continually speaking

Out of the sky,
Eyes Earthbound,
Stalagmite in open cavern,
Fertile lands all around.

The era of design,
Like a Justice Hall,
Women in bonnets,
Mennonite clothes,

In the Town of Williams,
Some time ago,
In the late eighteen hundreds,
Scenery I know.

by Platohagel

 Before I begin I just wanted to say I am deeply connected to the science today and what I am displaying now may not sit well with scientists.  Those who discount subjectivity as a part of our existence not tried and tested. This subjective existence\experience is real and very individual. How could you discount this from a point of a view of a scientist.  I thought they might say, but yes,  lived with responsibility and in a true validated sense?

So it was in this sense that one could consider the exercise that follows as a science fiction possibility that raises the questions about time and the relationship of the probability distribution of a possible future and the lived past. The present, in becoming, and in this case,  I wanted to look at the past.

The question is that we know that the world of subjective influences and experiences are deeply personal in that they become the life you have live. We work all day and we work all night in the virtual realities.You discover the Intent in the Actualized?

This distinction if not understood within the parameters of the subject entertained it would have lacked the understanding that our virtual reality within the confines of the parameters as being explicit in what we create would have been missed. I can talk about such a park and you might believe the context of such an example if I were to tell you that I was able to remember that at a very young age.

Can an individual experience the actualized past as if viewing a place in our history as part of that history. These questions had crossed my mind over 35 years ago as I explored the dream world. I tried to keep as much of this in poetic form dreaming as I was experiencing it. So I thought it would be nice to write it down in that form.

Now there are many reasons why this area of subjectivity was of interest to me. It was in that what I believed, that not only our footprints left an image in the sand, but our impressions of our life was in the footprints.

Two section variable capacitor, used in superhet receiver

Technically such excursions would have been of interest if I could track the ability by some means. So it was not beyond me to think that a tuning could take place by some individuals in helping to reconstruct the past  by going back in time. Not only by Carbon dating. But possibly by some other technical means as well in terms of a super heterodyne solution.

Now I am sure the idea of a fireman and a radio might be trigger in your mind. Aurora flickering in the sky and a son who goes to work on his Dad's radio?  You will find many references to time travel in this blog because of this idea I have had for a long time about our the ability each of has to visit the historical past as an Intent in the Actualized.

Frequency is a 2000 science-fiction film that contains elements of the time travel, thriller and alternate history film genres.

So the idea for me here was about creating a device that could tune into the past? Why then, is it we are not capable in consciousness as a virtual reality?

The Super Hero Versions

Miracles StudiosThrone Plates

To activate Thorne plates, the distance between each plate must be less than the width of an atom. The resulting wormhole will be equally small, so getting in and out might be difficult. To widen the portal, some scientists suggest using a laser to inject immense amounts of negative energy. In addition, Thorne believes that radiation effects created by gravitons, or particles of gravity, might fry you as you enter the wormhole. According to string theory, however, this probably won't happen, so it's scant reason to cancel your trip.

Miracles StudiosGott Loop

To take you back one year, the string must weigh about half as much as the Milky Way galaxy. You'll need a mighty big spaceship to make that rectangle.

Many scientists believe the big bang that created the universe left behind cosmic strings - thin, infinitely long filaments of compressed matter. In 1991, Princeton physicist J. Richard Gott discovered that two of these structures, arranged in parallel and moving in opposite directions, would warp space-time to allow travel to the past. He later reworked the idea to involve a single cosmic-string loop. A Gott loop can take you back in time but not forward. The guide to building your own:

Miracles StudiosGott Shell

This is a relatively slow method of time travel, and life inside the shell could become tedious.

In essence, a Gott shell is a huge concentration of mass. The shell's sheer density creates a gravitational field that slows down the clock for anyone enclosed within it. Outside, time rolls along at its familiar pace, but inside, it creeps. Thus the Gott shell is useful for travel into the future only. If you're planning a jaunt to the past using a Gott loop, you might want to bring along a Gott shell for the return trip. What to do, step by step:

Miracles StudiosVan Stokum Cylinder

The cylinder must be infinitely long, which could add slightly to its cost.

Mass and energy act on space-time like a rock thrown into a pond: the bigger the rock, the bigger the ripples. Physicist W. J. van Stockum realized in 1937 that an immense cylinder spinning at near-light speed will stir space-time as though it were molasses, pulling it along as the cylinder turns. Although Van Stockum himself didn't recognize it, anyone orbiting such a cylinder in the direction of the spin will be caught in the current and, from the perspective of a distant observer, exceed the speed of light. The result: Time flows backward. Circle the cylinder in the other direction with just the right trajectory, and this machine can take you into the future as well. How it works:

Kerr Ring

The Kerr ring is a one-way ticket. The black hole's gravity is so great that, once you step through it, you won't be able to return.

When Karl Schwarzschild solved Einstein's equations in 1917, he found that stars can collapse into infinitesimally small points in space - what we now call black holes. Four decades later, physicist Roy Kerr discovered that some stars are saved from total collapse and become rotating rings. Kerr didn't regard these rings as time machines. However, because their intense gravity distorts space-time, and because they permit large objects to enter on one side and exit on the other in one piece, Kerr-type black holes can serve as portals to the past or the future. If finding one with the proper dimensions is too much trouble, you can always build one yourself:

What Is Déjà Vu?

***

Déjà vu (French pronunciation: [deʒa vy] ( listen), literally "already seen") is the experience of feeling sure that one has already witnessed or experienced a current situation, even though the exact circumstances of the prior encounter are uncertain and were perhaps imagined. The term was coined by a French psychic researcher, Émile Boirac (1851–1917) in his book L'Avenir des sciences psychiques ("The Future of Psychic Sciences"), which expanded upon an essay he wrote while an undergraduate. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eeriness", "strangeness", "weirdness", or what Sigmund Freud calls "the uncanny". The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience has genuinely happened in the past.^[1]

 Scientific research

The psychologist Edward B. Titchener in his book A Textbook of Psychology (1928), wrote that déjà vu is caused by a person getting a brief glimpse of an object or situation prior to full conscious perception, resulting in a false sense of familiarity.^[2] The explanation that has mostly been accepted of déjà vu is not that it is an act of "precognition" or "prophecy", but rather that it is an anomaly of memory, giving the false impression that an experience is "being recalled".^[3][4] This explanation is supported by the fact that the sense of "recollection" at the time is strong in most cases, but that the circumstances of the "previous" experience (when, where, and how the earlier experience occurred) are quite uncertain or believed to be impossible. Likewise, as time passes, subjects can exhibit a strong recollection of having the "unsettling" experience of déjà vu itself, but little or no recollection of the specifics of the event(s) or circumstance(s) they were "remembering" when they had the déjà vu experience. In particular, this may result from an overlap between the neurological systems responsible for short-term memory and those responsible for long-term memory (events which are perceived as being in the past). The events would be stored into memory before the conscious part of the brain even receives the information and processes it.^{[citation needed]}

 Links with disorders

Early researchers tried to establish a link between déjà vu and serious psychopathology such as schizophrenia, anxiety, and dissociative identity disorder, and failed to find the experience of some diagnostic value. There does not seem to be a special association between déjà vu and schizophrenia or other psychiatric conditions.^[5] The strongest pathological association of déjà vu is with temporal lobe epilepsy.^[6][7] This correlation has led some researchers to speculate that the experience of déjà vu is possibly a neurological anomaly related to improper electrical discharge in the brain. As most people suffer a mild (i.e. non-pathological) epileptic episode regularly (e.g. a hypnagogic jerk, the sudden "jolt" that frequently, but not always, occurs just prior to falling asleep) it is conjectured that a similar (mild) neurological aberration occurs in the experience of déjà vu, resulting in an erroneous sensation of memory.

 Pharmacology

Certain drugs increase the chances of déjà vu occurring in the user. Some pharmaceutical drugs, when taken together, have also been implicated in the cause of déjà vu. Taiminen and Jääskeläinen (2001)^[8] reported the case of an otherwise healthy male who started experiencing intense and recurrent sensations of déjà vu upon taking the drugs amantadine and phenylpropanolamine together to relieve flu symptoms. He found the experience so interesting that he completed the full course of his treatment and reported it to the psychologists to write up as a case study. Due to the dopaminergic action of the drugs and previous findings from electrode stimulation of the brain (e.g. Bancaud, Brunet-Bourgin, Chauvel, & Halgren, 1994),^[9] Taiminen and Jääskeläinen speculate that déjà vu occurs as a result of hyperdopaminergic action in the mesial temporal areas of the brain.

 Memory-based explanations

The similarity between a déjà-vu-eliciting stimulus and an existing, but different, memory trace may lead to the sensation.^[5][10] Thus, encountering something which evokes the implicit associations of an experience or sensation that cannot be remembered may lead to déjà vu. In an effort to experimentally reproduce the sensation, Banister and Zangwill (1941)^[11][12] used hypnosis to give participants posthypnotic amnesia for material they had already seen. When this was later re-encountered, the restricted activation caused thereafter by the posthypnotic amnesia resulted in three of the 10 participants reporting what the authors termed "paramnesias". Memory-based explanations may lead to the development of a number of non-invasive experimental methods by which a long sought-after analogue of déjà vu can be reliably produced that would allow it to be tested under well-controlled experimental conditions. Cleary^[10] suggests that déjà vu may be a form of familiarity-based recognition (recognition that is based on a feeling of familiarity with a situation) and that laboratory methods of probing familiarity-based recognition hold promise for probing déjà vu in laboratory settings. Another possible explanation for the phenomenon of déjà vu is the occurrence of "cryptomnesia", which is where information learned is forgotten but nevertheless stored in the brain, and similar occurrences invoke the contained knowledge, leading to a feeling of familiarity because of the situation, event or emotional/vocal content, known as "déjà vu".

 Parapsychology

Some parapsychologists have advocated some unorthodox interpretations of déjà vu. Ian Stevenson and a minority of other researchers have written that some cases of déjà vu might be explained on the basis of reincarnation.^[13][14] Anthony Peake has written that déjà vu experiences occur as people are living their lives not for the first time but at least the second.^[15]

 Related phenomena

 Jamais vu

Main article: Jamais vu

Jamais vu (from French, meaning "never seen") is a term in psychology which is used to describe any familiar situation which is not recognized by the observer.
Often described as the opposite of déjà vu, jamais vu involves a sense of eeriness and the observer's impression of seeing the situation for the first time, despite rationally knowing that he or she has been in the situation before. Jamais vu is more commonly explained as when a person momentarily does not recognize a word, person, or place that they already know. Jamais vu is sometimes associated with certain types of aphasia, amnesia, and epilepsy.
Theoretically, as seen below, a jamais vu feeling in a sufferer of a delirious disorder or intoxication could result in a delirious explanation of it, such as in the Capgras delusion, in which the patient takes a person known by him or her for a false double or impostor. If the impostor is himself, the clinical setting would be the same as the one described as depersonalisation, hence jamais vus of oneself or of the very "reality of reality", are termed depersonalisation (or surreality) feelings.
Times Online reports (see semantic satiation):

Chris Moulin, of the University of Leeds, asked 95 volunteers to write out "door" 30 times in 60 seconds. At the International Conference on Memory in Sydney last week he reported that 68 percent of the volunteers showed symptoms of jamais vu, such as beginning to doubt that "door" was a real word. Dr. Moulin believes that a similar brain fatigue underlies a phenomenon observed in some schizophrenia patients: that a familiar person has been replaced by an impostor. Dr. Moulin suggests they could be suffering from chronic jamais vu.^[16]

 Presque vu (Tip of the tongue)

Main article: Tip of the tongue

Déjà vu is similar to, but distinct from, the phenomenon called tip of the tongue, a situation when someone cannot recall a familiar word or name, but with effort one eventually recalls the elusive memory. In contrast, déjà vu is a feeling that the present situation has occurred before, but the details are elusive because the situation never happened before.
Presque vu (from French, meaning "almost seen") is the sensation of being on the brink of an epiphany. Often very disorienting and distracting, presque vu rarely leads to an actual breakthrough. Frequently, one experiencing presque vu will say that they have something "on the tip of my tongue".

 Déjà entendu

Déjà entendu, (literally "already heard") is the experience of feeling sure that one has already heard something, even though the exact details are uncertain and were perhaps imagined.^[17][18]

 Reja vu

The feeling something that has happened or is happening will happen again, possibly in the near future, possibly in the distant future.

 In popular culture

 Film

Déjà vu provides a plot point in The Matrix, a 1999 science fiction-action film written and directed by Larry and Andy Wachowski. The protagonist, Neo, glances at a black cat and comments that he has just experienced déjà vu. Those with a knowledge of 'The Matrix' and its internal workings state that déjà vu means something within the Matrix was altered from its prior state and is referred to as a "glitch".
The 2006 science fiction film Déjà Vu revolves around a US federal law enforcement officer using an instrument called Snowhite to view the past 4 and a half days of anywhere in the world (limited radius as permissible by the program) in order to solve a murder and a terrorist bomb attack on a ferry that was being boarded by about 500 citizens and military members.

 Television

Déjà Vu was the third episode of the second season of Monty Python's Flying Circus, a British comedy program. Michael Palin plays a television host with the problem.^[19]
The concept is explored in the episode 119 of Garfield and Friends in the Orson's Farm segment.
The final episode of season 1 of Charmed, called "Déjà Vu All Over Again" sees Phoebe Halliwell reliving the same day over and over again at the hands of a demon named Tempus.^[20]
Déjà Vu is also a recurring plot element on Fringe. In the Season One episode, "The Road Not Taken", Olivia described the experience of déjà vu to Walter after she briefly experienced an alternate reality as the result of being a Cortexiphan subject. In the Season Two episode "White Tulip", Olivia experiences déjà vu while investigating the apartment of a time traveler who reset the timeline.
Déjà Vu is also a plot element in the "Mystery Episode" of the television series Supernatural where Sam Winchester wakes up in the same day as a result of being trapped in a time loop.

First came the heterodyne. The principle of "beats" or difference tones between simultaneous audio pitches was well known since antiquity, but Reginald Fessenden in 1901 was the first to apply the principle to radio transmissions [3]. Originally both radio frequencies were to be transmitted, received with two antennas, and combined in a detector. Later a local oscillator was substituted for one of the transmitter-receiver combinations and the heterodyne as we know it was born. Fessenden himself coined the term, from the Greek heteros (other) and dynamis (force).Who Invented the Superheterodyne?
