The strange physics of (raw) spaghetti

From Heisenberg’s Uncertainty Principle to Quantum Non-Spatiality

What you will find below is a (quite long) video of mine, told in my typical “macaronic English”!

In it, I will (try to) explain a number of things about Heisenberg’s Uncertainty Principle, Compton’s effect, Bohr’s Complementarity Principle, the Reality criterion of Einstein, Podolski and Rosen, the mysterious non-spatiality of quantum entities… and many other things as well.

The content of the video is not technically difficult. Actually, it’s pretty simple. However, conceptually speaking, it is also a little subtle.

But I can guarantee you that it’s worth the effort!

At the time I’m writing, there are just 4 comments below the video (on YouTube), which so far received 5,605 views; but they are certainly encouraging:

“Great”
“Very very good explanations! Thank you for making this fantastic video!”
“Very well explained”
“Great video! greetings from Zurich”

Let me reproduce below two brief excerpts taken from the video, just to stimulate your curiosity.

Praying and smoking


A novice asked the prior:
“Father, can I smoke when I pray?”
And he was severely reprimanded.
A second novice asked the prior:
“Father, can I pray when I smoke?”
And he was praised for his devotion.

“To pray and smoke” does not produce the same effect as “to smoke and pray.” Here the non-commutability is expressed through the order chosen for the verbs “to smoke” and “to pray,” in a sentence. If you switch the order of the verbs, you also change the perceived sense of the phrase. The verbs, in fact, indicate actions, that is, operations that we perform, which is the reason why their order in a sentence is sometimes so important. What we must understand is that in general the order with which we operate in reality affects the final result! To succesfully assemble IKEA furnitures, it is necessary to operate in exactly the sequence indicated in the instruction manual, if you want to get the desired result.


Space and Reality


Reality is not contained within space. Space is a momentaneous crystallization of a theatre for reality where the motions and interactions of the macroscopic material and energetic entities take place. But other entities — like quantum entities for example — “take place” outside space, or — and this would be another way of saying the same thing — within a space that is not the three dimensional Euclidean space.” [Diederik Aerts]

Our three-dimensional space, in which we live, with our macroscopic physical body, is a small theater, which cannot contain all of reality. Reality is much bigger than that: it cannot be all represented on this narrow three-dimensional stage. There are other venues out there, that can accommodate entities genuinely non-spatial in nature, such as electrons, protons, neutron, quarks… entities whose spatiality is of a very different kind, decidedly non-ordinary. But then, if the microscopic entities generally do not have a position in space, what exactly does this mean? How can we understand a process through which a physicist, under certain experimental conditions, is able to detect the spatial position of a microscopic elementary entity?


Here is the video: enjoy!

… and yes, if you liked it, you can share it, there are no contraindications :-)

…and by the way, recently I also wrote an article containing the (revised and slightly expanded) “transliteration’’ of the above video, which you can download here. This will offer you the possibility to retrace its contents in a form not only stylistically a bit more accurate, but also, perhaps, more suitable for the continuation of your reflection about its content.
