Grab La Realtà Non è Come Ci Appare: La Struttura Elementare Delle Cose Engineered By Carlo Rovelli Digital

be honest and up front, I only wanted to read more into Loop Quantum Gravity,

Say what! Well, it's the leading contender against String theory, It doesn't try to mash together the main problem area of gravity with quantum mechanics, but rather extends quantum mechanics as a granular geometric equation into the macro realm of what we understand as special relativity.


In other words, Reality is finite, quantifiable, and can be extrapolated from the underpinnings of the general field of quantum mechanics.


If you know anything about the underlying basis of string theory, this idea is both flabbergasting and simplistic.
And maybe, it's also correct,

I can't say for certain, and as far as I can tell, neither can the author.
Most of the book gives us a survey of the underpinnings of reality physics from the conceptualization of the atom through Einstein's reformulation of heat energy on the equilibrium of those atoms in their environmental matrices.
EMC squared

Spin Foam is the name of the minimum Planck distance that forces atoms into discrete and quantifiable distances between each other.
It's the reason why atoms don't just fall into singularities like black holes or crushed neutronium states under normal gravitic circumstances.
It's not merely probability shells and energy levels, but quantum loops that behave like bubbles forcing certain distances.
. . and therefore forcing Matter to behave the way it apparently behaves, . . making atomic structure.

The most interesting idea I'm getting from this is the idea of the Big Bounce, In other words, the cause of the great expansion once the Big Bang got lit, It reminds me a lot of how iron molecules make burp in the process of digesting fusion and cause a nova.
Only we're dealing with a quantum state that coaxes atoms into creation through special wave functions behaving like granular notations.
You know, like how light behaves like both a wave and a particle,

And beyond this, . . I'm completely lost. :

I don't know the math but this book is pretty decent on the conceptual side, The basics are commonplace and I was mainly into it for the later weird stuff,

But all in all Rovelli is a very, very good writer, Convincing. Clear.

It may not be the answer to the great question of our day and age, but he makes a very good case.
: OK, I give up because this is making me too angry,

The errors are multitudinous, egregious and recognisable by any physics final year undergrad worth the name.
The final straw was the claim that "particles don't exist when they are not interacting, " This notion is an obvious breach of conservation of energy and not supported by quantum theory, which states that insofar as conservation laws can be breached at all, there is a time limit.
It's given by the famous Heisenberg Uncertainty Principle and put simply, it says that the more energy you want to "borrow" the less time you can do so for.
The energy of entire particles is large in this context they can't cease to exist for long periods.
This is experimentally verified in accelerator experiments such as the Large Hadron Collider, where it's found that any time a particle emits another, or changes into one or more others, it takes a finite length of time but a ridiculously short one.
Different for different types of event, btw,

Anyway, I can't face any more of this right now instead of pointing out every error and misconceptiion I'm just going to have to draw a line and say: DO NOT READ THIS BOOK: It's full of falsities and misleading bullshit.
I finished it, for which I deserve five, The author used great illustrations, for which he deserves five,

However, I think the author should have described certain quantum ideas, like 'spin networks' and loops with more illustrations and longer chapters and more words rooted in common everyday language but on the other hand, my brain grasps liberal arts with ease while I flounder and drown in math conceptualizations, not to mention in solving highermath equations.
Maybe the author DID describe accurately those things,

The author has extensive notes, an annotated bibliography and an index, As far as I can tell, this is a fantastic book, The author certainly tried very very hard to make quantum mechanics understandable, Enlightenment à la Rovelli serves

, Divide the Dante into equal halves and fasten together with a good transdimensional adhesive to form asphere.
Be careful not to get any glue in the primum mobile, Set aside to dry.

. Stir the Lucretius, Galileo, Newton, Einstein and Heisenberg until thoroughly mixed, Add a little Anaximander to taste, Put in a warm place until it has risen,

. Add the Feynman path integral and the lattice approximation to the spacetime, Whisk into a spinfoam using a quantised volume operator, Make sure the fields are covariant,

. Pour the historical influences and the ἄπειρον into Canto XXXIII of the Paradiso, Squint

at the mathematical footnotes so that you intuitively grasp the significance of the formulas without actually reading them.
You may not get this right first time, but it is definitely worth the trouble, Wait for the enlightenment to take effect,


My girlfriend and I ordered this recently at the CERN cafeteria, I thought it was delicious, but in the interests of full disclosure I am forced to admit that my girlfriend was very disappointed.
She said it tasted of penguin and she was sure the spoon used to serve it had previously been used for the Joël Dicker.
I had no idea what she was talking about and ate her portion too,

I also have a serious review sitelinkhere, “ let's look at the Earth, then you'll see there are things that stand still and things that will sooner or later come to a standstill, that is, at the moment they happen to be moving from one place to another, there is stoppage and delayed stoppage, there are two if we consider only the Earth and the way we see it, but if we take the realm of the invisible where, let's say, he says, neutrons and protons and electrons and hadrons and leptons and quarks and bosons and superpartners bicker and so on and so forth where the series endlessly continuable as time passes because they too are only assembled out of something well, no matter, the point that here we see motion, the interruption or stoppage of which, how shall I say deferred forever, so that we have stoppage and motion, but behind both, and pay attention now, he says, there is that elusive, unfathomable gigasystem that determines what is it going to be, stoppage or motion, and beyond the world there are other worlds, every world perfectly conceals another world, of course, although the whole thing can also be expressed by saying that any one world is only a gateway, a secret door to billions of worlds.

László Krasznahorkai words of a drunk in Budapest in The World Goes On

“Hold Infinity in the palm of your hand
And Eternity in an hour.
” William Blake

When I was between the ages ofand, my family lived across the street from a cemetery.
No there are no extraphysical beings in this review, On warm, summer, prairie evenings, I would wander over and lay down in the grass to watch the sky.
This was a time when I had rejected the totality of the human race, The peace of the cemetery was welcoming, I saw a great deal, both above me and in my thoughts,

I recall the sparrow hawks circling overhead and then dropping from above at tremendous speeds to capture the unsuspecting insects that flew into the paths of the open jaws of the birds.
And I waited each time for the swoosh of the wind through their wings as they pulled out of their seemingly inevitable meeting with the earth.
I never lost the wonder of it,

And every night, the darkness came, or better, the light that pushed back the darkness came and I entered into a world of my imagination at its best.
I lay trying to imagine those two greatest enigmas for me having written off humanity infinity and eternity.
I had not yet heard of William Blake, but I was delighted when I first read Auguries of Innocence despite its religious overtones.


I would lie there for hours watching the sky roll by and becoming entranced with my own thoughts.
It was my childhood version of Zen, I was less concerned with finding an answer to my questioning and more taken by my state of mind.
I realized that I could never really imagine a universe that stretched on infinitely nor could I imagine one that had limits.
What could be beyond the limits

The same types of ideas arose around eternity, How could time stretch backwards and forwards without beginning or ending And what did that all mean anyway I lay there boggling my mind and thoroughly bewildering myself.
Interestingly, it never occurred to me that science could help with this, In the earlys, we learned nothing beyond seventeenth century science, and not much of that, Until recently, I never tried to grasp anything about Quantum Physics, Ive been more the poet than the scientist, Now I struggle with the most basic concepts, Carlo Rovelli is trying to help, He also wants to explain that he too has the heart of a poet, Im not sure.

So, what would Rovelli make of my childhood reveries Well, he would, and has, among many other things, explained to me that space and time, at least in my sense, do not do not really exist.
And, I suppose, that Blake had it wrong, There are particles and there are relationships between these particles but my concerns have been misplaced, Well, misplaced in any ultimate sense, I have immersed myself in enough Madhyamaka Buddhist thinking to be able to understand that I can distinguish conventional stuff from ultimate or absolute stuff and that the absolute stuff is not only unknowable but is not reality.
And of course, such ideas would seem at times to be where Rovelli and I part company, But then, maybe not. I do not even agree with his use of the word “reality”, His definition seems to meander,

Some quotes:

“And it is reliability that we need, not certainty, We don't have absolute certainty, and never will have unless accept blind belief, The most credible answers are the ones given by science, because science is the search for the most credible answers available, not for answers pretending to certainty.
”


“ parts of an indispensable grammar for understanding the world, This grammar has evolved, and is still in the process, ”


“water A wave is not an object, in the sense that it is not made of matter that travels with it.
The atoms of our body, as well flow in and away from us, We, like waves and like all objects, are events we are processes, for a brief time monotonous, . Quantum mechanics does not describe objects: it describes processes and events that are junction points between processes, ”


“What makes a subject hard to understand if it's something significant and important is not that before you can understand it you need to be specially trained in abstruse matters, but the contrast between understanding the subject and what most people want to see.
Because of this the very things that are most obvious may become the hardest of all to understand.
What has to be overcome is a difficulty having to do with the will, rather than with the intellect.
The reason there is so much "resistance of will" is because we wrongly assume that that which we are explaining resides in some foundation beyond us, be it God or the foundation of the physical world, namely,.
particles. We need to see that we and our surroundings are the foundations, and we describe these, we do not explain them just as we do not explain our consciousness rather, we are conscious.
”

I would like to agree with Rovelli on this last point, I really would, but I do not know that he has succeeded.
He has not completely, in my case anyway, been able to convert his formulas and numbers into language that I can totally grasp.
Too much of what he presents is in the form of metaphors, and until those metaphors become so deeply embedded in our daily speech, the are only metaphors.
I dont know that I can wait that long,

Where Rovelli has succeeded is in further eroding those metaphors of my past, I will no longer look at the night sky in search of limiting walls to the universe, I shall simply continue to wonder perhaps in cemeteries at night, and read, of course. .
