I see, charge is a class method and not an instance method. Well played universe creator.
Fuck I knew it was made with OOP
Nobody wants to covalent anymore.
Fine, I’ll do it myself
-ThelectronYou have to be bonded and that’s a whole bureaucratic mess.
This is why in general I prefer fission.
How about in specific? Or is it all relative?
Don’t most sub-atomic particles have the same charge and mass? Why just electrons?
You’d have to ask John Wheeler, which would be difficult since he died in 2008.
Just get the electron to ask him next time it goes back in time, duh
I would, but I only speak positronic.
Data?!
Nah, I only speak positronic. He thinks it.
The whole thing is an abstraction. The nucleus isn’t actually tiny ball shaped things mashed together, but rather cloudy stuff which would probably not be identical if we could actually see them. The quarks that make up protons and neutrons are considered elementary particles and identical, but they don’t move around much unless energy is used to split them.
The electron however is an elementary particle that moves outside of the nucleus and can move from one atom to another. So the hypothesis is that if we could follow one electron from the big bang to the end of the universe, and this electron could move both forwards and backwards in time, it would potentially be enough with just one.
It probably doesn’t hold up very well, but it’s an interesting thought experiment.

It’s one of those things which would be pretty much impossible to prove, but it holds well with the effects we currently see. Electrons can annihilate by colliding with positrons. But the collision we see could be a single electron changing from moving forwards in time to moving backwards in time. It holds that it’s the same particle in the equations by cancelling out the minus sign of the charge with the minus sign in the time. So while we see a collision, the electron would just see itself changing charge and start moving backwards in time instead.
It’s a beautiful hypothesis, and fills me with chills to think about the electron “experiencing” all of history an unimmaginable amount of times.
A big part of quantum mechanics is the fact that matter can show wave-like behaviour, which sort of breaks a bunch of “rules” that we have from classical physics. This only is relevant if we’re looking at stuff at a teensy tiny scale.
Someone else has already mentioned that electrons are a fair bit smaller than protons and neutrons (around 1840 times smaller) and this means they tend to have a smaller momentum than protons or neutrons, which means they have a larger wavelength, which was easier to measure experimentally. That’s likely why electrons were a part of this theory, because they’re small enough that they’re sort of a perfect way to study the idea of things that are both particle and wave, but also neither. In 1940, quantum mechanics and particle physics were super rapidly moving fields, where our knowledge hadn’t congealed much yet. What was clear was that electrons get up to some absolute nonsense behaviour that broke our understanding of how the world worked.
I like the results of some of the worked examples here: https://www.chemteam.info/Electrons/deBroglie-Equation.html , especially the one where they work out what the wavelength of a baseball would be (because that too, could theoretically act like a wave, it would just have an impossibly small wavelength)
TL;DR: electrons are smaller than protons/neutrons Smaller = larger wavelength Larger wavelength = easier to make experiments to see wave-like behaviour from the particle Therefore electrons were useful in figuring out how the heck a particle can have a wavelength and act like a wave
I detect you therefore you’re no longer a wave.
I like the way one of my university textbooks frames the particle wave duality thing: “A single pure wave has a perfectly defined wavelength, and thus an exact energy, but has no position. […] [Whereas a classical particle] would have a perfectly defined position but no definable wavelength and thus an undefined energy” ([1][2])
I am currently in my bed. I have a lot to do today, but I’m not sure how much I will get done because I don’t know how much energy have. Thus I conclude you are right and that I am clearly a particle.

Makes sense, why should I keep waving when you can see me now.
Maybe, because we can measure the number of protons and neutrons with an ion accelerator? I don’t know if the something similar can be done with electrons.

We are all one consciousness experiencing itself subjectively.
Life is just a dream, and we are the imagination of ourselves. Here’s Tom with the weather!
Sorry mate, Tom couldn’t make it, so here we have Bill.
Weather update: it’s raining rocks from outer space
What a boson.
To his credit, Wheeler did try to make a quantum leap. It just wasn’t coherent. If he had kept at it, I’m sure he would have had momentum.
This comment gave me spin
I’m glad you realized the gravity of the situation.
This thread indicates you might have a bit of a strange quark.
Still very charming, though.
All ups, no downs.
I’m out in left field trying to figure out what’s happening?
Shouldn’t be just electrons though - don’t all instances of any given type of subatomic particle have the same mass and charge?
So, if route all of the electricity in my house through my body, how far can I travel in time? What about a car battery’s worth?
Sorry, you need 1.21 jiggawats.
I’m going to have to modify my juicer.
Don’t forget to move 66 mph in the direction of the past. Or future, whatever floats your time boat.
What direction is southeast?
Yes.
One reason why that is probably not true is because there are less positrons but if it were true they should number the same as electrons, right?
But if electrons are moving along the same “time direction” as we are and positrons are moving in the opposite “direction” then wouldn’t we expect there to be less protons? As we can’t measure the protons that already “passed” us? And we would measure more electrons as a some/many/all of the existing electrons are traveling alongside us?
I think you may have put more thought into this than Feynman. But then he probably had someone waiting for him in bed…
I know! Horrible isn’t it? I just can’t help it, thinking about stuff is actually fun for me… so embarrassing!
It was more a joke about how Feynman had two great loves: physics and fucking. And probably fucking more than physics.
Ah I see ;) I also have two loves, but my gaming pc is too heavy to drag to bed…
Wait, I’m lost. What does it have to do with the amount of protons?
Positrons are different from protons. Both have a positive charge, but a positron is an elementary particle of a similar mass as an electron. They are rather rare in nature which OP was noting. Protons are made of three elementary particles, much heavier than positrons, and are, I imagine, present in nature in about the same order of magnitude as electrons.
positrons are just really far away
The higher dimensional abstractum of the electron emanates through the multiverse. Electron is.
