Where is escaped, the electron that until now hovered within the cathode ray tube of our TV?
It seems that this electron is really a joker, while it is heading towards the screen …
We can observe it while it appears in the “network” of pixels associated to our unit, and if it is perfectly comfortable and enjoys the journey, we can “eat our heart” there because we have no way to control – for wire and sign – its movements…
Oh yeah, you still know why… in fact we are hindered from being able to define its precise trajectory. The law is universal & no one is excluded. And the only thing sure is that this law is very democratic because each of us is aware of the uncertainty principle .
At least we can console ourselves with little something, waiting for a smile given by some genius of physics. There is an experiment, well known, that can comes in handy to study the displacement of this electron:
We have a cathode (device that emits electrons) that works a bit ‘as a launch pad from which a flow of electrons (also called cathode ray) comes out very quickly, thanks to the electric field therein.
Our litmus test will be the anode of a glass screen, positioned in front of the cathode. We will note straight away that its wall is illuminated immediately, and this happens precisely for effect of each individual electron there directed, following – mainly – a straight line.
Why, myself and Fry are saying mainly?
The probability of finding an electron in a frontal position (having as a benchmark the negative cathode) is very high, but some electrons – the most spiteful – opt to move sideways.
Niels Bohr might say that quantum mechanics (according to him being a complete science) can help us understand the behavior – kinda odd, let me say it – of this electron.
But in fact, what we know upon the electron is that:
- It spreads in space like a wave (while maintaining the heteronomy of particles!)
- Choose – almost arbitrarily – where to want to move
- If we would illuminate in a direct manner a hypothetical barrier toward which it should direct, and we choose one of the two holes applicated there previously, we could influence its movement. How? light is made up of elementary units called photons … And as everyone knows, if you could shoot a photon at a given time, you would see the “deformation” that influences and creates it in the space by its oscillatory pattern (defined by an alternate maximum and minimum point).
- Its exhaustive description is still a mirage
At this point it is possible to ask ourselves, what are the essential characteristics of reality independently of our ability (and the sensitive instruments available) of observation. And by our arbitrary saddled attributes to what we can observe. Well, this fairly problematic point is the subject of reflections from two schools of thought.
One observes it in a realistic way and what it proposed is the classic objective reality, in which the electron exist by itself, and the fact of wanting to detect the exact location is irrelevant to his presence.
The second one, on the heels of Bohr, question the reality to reveal its microscopic secrets, and to its electrons to tell something more than we know today.
in short, their range MUST become / or be as defined as possible!
And to you, which of the two is more sympathetic :-)?
Rather, please excuse this phrase, perhaps too familiar …
Which of these two possibilities seems more plausible?
It seems that, waiting to the next post, from now watching television will lead us to move our gaze and immagination to the lost electron research. Is it right?
