Standing on Giants... But Be Careful of Heights

 About a month ago, I wrote about the importance of “standing on the shoulders of giants,” in my note "Standing on the Shoulders of Giants: The Unsung Path to Innovation". My advice then was simple: when embarking on a new project or tackling a complex problem, follow the wisdom of Newton—find your giants, climb on their shoulders, and use the elevated view to dream bigger and contribute to humanity’s understanding.

Well, life has a funny way of teaching lessons, and after a recent event, my enthusiasm for climbing those metaphorical shoulders has waned. Sometimes, when you climb too high, you risk falling flat on your backside—painfully.



A Roller Coaster of Peer Review

As a member of several publishing boards, part of my job is determining whether a submitted paper deserves to grace the pages of an academic journal. Recently, I had to evaluate a paper on foundations of quantum mechanics, which, as you might imagine, had stirred up quite the debate among its reviewers. Two gave it positive, albeit superficial, reviews, while one reviewer passionately tore it apart, backed by meticulous analysis.

Now, quantum mechanics is close to my heart, so I dove in headfirst. The paper referenced Freeman Dyson, particularly his work Why is Maxwell’s Theory So Hard to Understand?”. Dyson, as many in the field will know, is no lightweight. The man’s a legend—he’s responsible for everything from Dyson spheres to eternal intelligence. If there’s a Mount Olympus for physicists, Dyson is sitting comfortably at the top.



But then things started to get interesting...

Enter Dyson's World of Confusion

As I waded through Dyson's work on Maxwell’s electrodynamic theory, I couldn’t help but admire his writing. He starts strong, with captivating lines like:

"The importance of Maxwell's work was not obvious to his contemporaries... For more than twenty years, his theory of electromagnetism was largely ignored. Physicists found it hard to understand because the equations were complicated. Mathematicians found it hard to understand because Maxwell used physical language to explain it.”

I was nodding along enthusiastically. Yes, yes! Physics and math not always seeing eye-to-eye—makes perfect sense.

Then, Dyson drops this gem about modesty (or the lack thereof):

"Modesty is not always a virtue. Maxwell’s modesty set back the progress of physics by twenty years. Mendel’s modesty set back biology by fifty years. If people make great discoveries, they should not be too modest to blow their own trumpets."

Ah! A philosophical nugget! And there I was, suddenly hit with an uncomfortable realization. I’d been too modest with my own work—my EEQT theory. Out of some misplaced humility, I even skipped presenting my own research at an international conference I helped organize. What was I thinking? As Dyson says, modesty sometimes just gets in the way of progress!

Physics or Philosophical Puzzle?

But just as I was patting myself on the back for learning this life lesson, Dyson took a turn into some rather strange territory.

"The conventional unit of electric field strength is the square root of a joule per cubic meter... a square root of a joule is not a unit of anything tangible... The unit of electric field strength is a mathematical abstraction.(...) It means that an electric field-strength is an abstract quantity, incommensurable with any quantities that we can measure directly.

Wait, what?

At this point, my brain started doing somersaults. Dyson wasn’t talking about some esoteric theory or the philosophical implications of physics—he was talking about electric field strength. This is something you can measure, right? I mean, you can feel a magnetic field pulling a compass needle, and the Lorentz force acts on charges in an electric field. These aren’t just abstract notions.

I was genuinely torn. Am I in the wrong universe? Has the physics I know and love been lying to me all these years? Maybe I should go back to elementary school physics or, as Dyson would suggest, just trust the giant and move on without asking too many questions. Perhaps, dear reader, you can help me untangle this mess?

The Verdict: A Paper with No Punch

Now, back to that quantum mechanics paper with the mixed reviews. After slogging through the Dyson-inspired bits, I realized the author had presented an entertaining read but brought nothing new to the table. It was like watching a well-acted movie with a plot you’ve seen a thousand times—pleasant, but no surprises.

Even though the author represented the Boeing Corporation (a bit of a giant themselves), I had to do the unthinkable. I recommended rejection. Sometimes, saying “no” is a duty, even when you’d rather say “yes.”

Lessons from the Fall

So, what have I learned from this strange journey through Dyson, modesty, and physics?

  1. Climbing on giants' shoulders is risky—you might see further, but the fall can be harder. Proceed with caution.
  2. Modesty isn’t always a virtue. Sometimes, it holds you back more than it helps.
  3. Not all giants are infallible. Even the best minds can baffle you, leaving you questioning your very existence—or at least your understanding of electric fields.

And with that, I’ll step off these lofty shoulders, bruised but wiser, ready to approach my next project with both caution and confidence.

P.S. 11-09-24 17:08 From yesterday's local newspaper:


A dog travels 160 km to find her owners

What was this dog measuring? Field energy density or field strength? And what kind of a field? EM field? Quantum wave function? Or some other "psi" field? I asked Grok how science explains these facts. Here is the answer I have obtained:

The phenomenon of pets, particularly dogs, traveling long distances to find their owners is indeed fascinating and has captured the interest of both scientists and animal behaviorists. Here are some of the scientific explanations and theories behind this:

  1. Scent Tracking: Dogs have an extraordinary sense of smell, estimated to be 10,000 to 100,000 times more acute than humans. They can potentially follow scent trails left by their owners, even over vast distances. This might involve not just direct scent but also familiar environmental smells that guide them.
  2. Magnetic Field Sensitivity: Some research suggests that dogs, like many migratory animals, might have a sensitivity to the Earth's magnetic field. This could help them navigate, similar to how birds, turtles, and other animals use geomagnetic cues for migration. This theory, however, is less proven in dogs compared to other species.
  3. Familiar Pathways and Memory: Dogs might remember routes they've traveled before or landmarks. If they've previously been to certain places with their owners, they could potentially retrace those steps. This requires a form of spatial memory, which dogs are known to possess.
  4. Behavioral Conditioning: Dogs are highly attuned to routines and patterns. If they've regularly traveled a certain route or have been to specific places with their owners, they might follow these familiar paths. This isn't navigation in the traditional sense but more of a behavioral pattern.
  5. Human Assistance: Sometimes, these stories involve some level of human intervention or coincidence, where the dog might have been picked up by someone and taken part of the way, or where the dog was following a general direction towards home and got help along the way.
  6. Instinctual Drive: There's an element of instinctual behavior where the bond between a dog and its owner can drive it to undertake such journeys. This isn't a scientific explanation per se but points to the emotional and psychological bond that might motivate such behavior.
  7. Environmental Cues: Dogs might use a combination of environmental cues like wind direction, sounds, and other sensory inputs that humans might not fully understand or recognize.
  8. Random Movement with Confirmation Bias: Some skeptics argue that not all dogs succeed in finding their owners, and those that do might be a combination of random movement and the human tendency to notice and report successful stories more than failures.

The scientific community doesn't have a definitive answer, and it's likely a combination of these factors rather than one singular explanation. Each case might involve different elements of these theories. The emotional drive to return home, combined with a dog's natural abilities, could lead to these remarkable stories of long-distance travel.

Remember, while these explanations provide a framework, each dog's journey could be unique, influenced by its individual experiences, health, determination, and perhaps a bit of luck.

I am not happy with this answer! Not happy at all. Wouldn't it be more important for humanity to study these kinds of phenomena instead of the "Higgs boson"?

  1. "It means that an electric field-strength is an abstract quantity, incommensurable with any quantities that we can measure directly."

    It all depends on what one means by direct measurement.

    Someone might think that we can directly measure only something that affects our senses (sight, hearing, touch, etc.) (light intensity, volume of sound, hardness, etc.)

    Someone else might think that we can directly measure everything that affects the apparatus that can give the result in numerical form.

    Dyson probably means that direct measurement is limited only to measuring energy (and possibly momentum). However, he rejects even the recognition of force measurement as a direct measurement, which is strange. (Old people can be odd.)

    1. My guess is that Dyson originally had something else in mind: electromagnetic potentials vs field strengths. Potentials are the first level - mathematically useful, sometimes even indispensable, but not observable, as they can undergo "gauge transformations". That would be similar to the two levels in quantum theory, where the phase of the wave function is also not directly observable and can be subjected to gauge transformations. But, as the text shows, while writing the article, he has changed his mind and wrote something hard to understand.
      There is some discussion of these issues here:

      https://physics.stackexchange.com/questions/137109/how-can-maxwell-theory-be-viewed-in-terms-of-two-layer-structure

      But it does not really helps with my confusion.

    2. "My guess is that Dyson originally ..."

      But he sees field stengths as not observable.

      I think he got confused....

    5. To measure energy density you need an instrument. To measure field strength, you need another instrument. That's all the difference.

  2. "Wait, what?"
    Exactly. Now you also have me scratching my head.
    The main question floating above it is, why did this giant of physics use energy to 'define' electric field strength, as energy itself is much more abstract than for example force, and relation to energy in the form of energy ~ (electric field strength)^2 is much more 'elusive' and mathematically based thing, than simple electric part of the Lorentz force, F = q*E?

    So, I'd definitely subscribe to your lesson #3, and just leave this giant's 'wise-acring' to himself. It seems that certain people, when they reach high places in tall white towers, tend to loose sight of where their feet are coming from. And unfortunately, more often than not, they are also greater impediment to genuine progress than their humbler counterparts which can easily get swayed by the perceived greatness of the giant. In the case of F. Dyson, I think the sad story of A. Wyler who Dyson invited to Princeton speaks enough by itself.

    1. Force is concrete but force per charge maybe not so much since what is charge. Charge might ultimately just be a multivector made from basis vectors thing which isn't exactly concrete.

  3. And, as far as I've been informed, the other giant in your series of posts, Newton, was even 'worse' than Dyson, degrading and using his fellow students, and stealing their work and works of others researchers as well, presenting that as his own achievements.
    I could have been incorrectly informed of course, so FWIW.

    1. Thanks. I read about Newton:
      "The inescapable truth is that Isaac Newton wasn't the flower sniffing, rosy individual our elementary teachers portrayed him to be. Cold and calculating, cunning and quick-tempered, he just was not a nice guy. Plain and simple"
