[@kamomilo3532]

That phrase itself is conceited in that it presumes that people are somehow beneath the almighty presence of the universe. There's no reason to place a hierarchy of values on the universe since we are in it, we're apart of it, we are made of it. Hairless apes isn't even an insult, its just a crude description of what we are. No different from calling space an "empty void". People just be doin what they do, if something doesn't make sense there's no reason to just go straight to shit status. For all we know we could be the way the universe is exploring itself or maybe our very existence is implicative of the universe and if we didn't exist neither would the universe. Not us specifically but life in general.

Yep. The “rules of the equation “ are the best we can do right now. The electron and proton (and all other “particles) are actually made of massless bits trapped by the Higgs field. These particles can’t get close because of the “Pauli exclusion principle “(another rule). Equations don’t mean they exist, but they just fit the data, so we have to deal with the math until we can do better. After all, we used to think the earth was the center of the universe!

This was the absolute best video I watched on quantum mechanics, and it solved all my confusions!

[@orri93]

I like your channel. When I was in University I took inorganic chemistry as a part of my B. S. degree in biochemistry. Because I have always been both a hobby and now a professional programmer I made a software to calculate and visualize the probability distribution of the e- in different orbitals for the H atom. Unfortunately I lost the code as this was some time ago :-) But watching this episode I was wondering, even if the distribution cloud of the proton is so small and there is very little probability that the e- will come close to it, the probability that the e- can end up inside the proton must be higher than zero, correct? If that is true, is it possible, though unlikely, that the electron could end up inside the proton and so that the negative charge would interact with the positive charge? Final question that I am most curious about, what would happen?

[@ArvinAsh]

Great question. Indeed this can happen. The wave extends to the inside of the nucleus. In large atoms, an electron can get absorbed into the nucleus, and would result in a change to a different element, or an isotope.

[@thedeemon]

Yes, higher than zero. Even better: for s orbitals the probability density is highest at the center! en.wikipedia.org/wiki/Hydrogen_atom#Visualizing_the_hydrogen_electron_orbitals The wave function already describes the whole state of the electron, it's not like the electron is a small ball that's sometimes here and sometimes there. The whole cloud is the electron, the wavefunction says it's a superposition of being at all those points, with different weights/amplitudes in that superposition, so in a sense that electron is already partly inside the nucleus all the time. Nothing more special happens, the shape of the electron's wavefunction in the hydrogen atom is already the result of the proton being there, result of the constant interaction. If you try to somehow squeeze that cloud to the proton size, localize the electron there, momentum for such wavefunction will be so high that it will very quickly expand back.

[@orri93]

@@ArvinAsh thank you for the answer and keep up the good work :-)

[@MrWildbill]

Great question and answer, this helped answer my question, so an electron wave can end up in the nucleus.

[@orri93]

​@@thedeemon I might be wrong, but I don't think you are correct about "the probability density is highest at the center". It has been so many years since I was playing around with the calculation in my C code (though I can remember it is not that complicated after taking basic math involving complex numbers - The code was less than about 100 lines). The problem with the visualization on the Wikipedia page you are refereeing to might be showing the surface of the "cloud" though I am not sure. If you look at Arvin Ash video again when he shows the graph for the Electronic Probability ( ψ^2 × r^2 ) by the distance from the nucleus (r) starting about 8:15 into the video, the graph starts from zero and then increase and peaks at 0.529 × 10^-10 m. But notice that the nucleus is so small compared to that peak. In the case of H atom the nucleus is just one proton so the size is 0.84-0.87 fm (or 0.84×10−15 to 0.87×10−15 m). You have a point about the electron not being a small ball and the cloud is in a superposition at all the posibilites. But what I asked about is if an interaction between the electron and the proton is theatrically possible. Because as I understand the quantum mechanism, an interaction would mean the collapse of the wave function for the electron or what I think is called decoherence. This is assuming that the electron and the proton are not entangled, correct? Or am I wrong about that? I am not saying you are wrong though because I don't know for sure, what the correct answer is. But your response made be think more about this and thank you for that. Respect.

When it does, the electron releases a photon of electromagnetic energy.

The problem for me came when he got to the Schrödinger Equation. I took college math through Diff EQ, and actually did better in that class than in any other, but it was long ago, and i just can’t “see it”.

one of the best explanations and intuitive graphics simulations I've seen, thanks for sharing.

Matter is braided waves, thank you for attending my TedTalk

10:28 - "This is definitive proof that our 3D model is likely correct". It's strange to have "definitive proof" that something is "likely".

[@MendTheWorld]

Strange, perhaps, but everything we encounter in the world, and all of our knowledge about it is inherently statistical (probabilistic) in nature. Anyone who claims certainty about _anything_ is exaggerating... but a “high probability” will be sufficient in nearly (ha-ha) all situations!

[@astroartie1872]

Actual proof of anything is relegated to the field of mathematics. In any other science we just have evidence (observations) that supports a theory (or, equivalently, a model) or rejects a theory. If a theory encounters evidence against it, the theory is wrong. It can either be fundamentally wrong, or it can be fixed with adjustments from new insights. Finding evidence in support of a theory, does not mean the theory is correct - all we can say is that we now have more evidence supporting it.

This may be one of the best video's I've ever seen on youtube. Thank you for explaining how Planck was fundamental to modern physics. I think I understood 40% of this video when watching without pausing.

Thanks for the historical overview of discovery!

[@drmichaelshea]

Humility is an indicator of true genius. Thank you. I would like to take these classes, but time is so limited!

[@acemanNL]

Have read all the comments. What can I say? Brilliant explanatory video!!! Thank you my friend!!! 😀

[@DanielleFormalejo]

Wonderful video! I've been trying to gain a conceptual understanding of the basis behind quantum mechanics, and this video provides for that perfectly!

[@royledford5673]

"Particle" and "wave" describe what electrons DO (relative to current conditions) not what they ARE. Electrons are minute packets of energy within an energy field that manifest according to demand. Max Planck nailed it over 100 years ago, "There is NO matter, as such". His entire statement of explanation that follows is the brilliant work of a beautiful mind.

[@Dante02d12]

Hey Arvin! Great video, as usual! I'm really struggling with the idea that an electron could be a cloud of probability. From what I understand, the wave function describes the positions the electron COULD take, but one electron would still be at one position. In fact, I see the orbitals (the "clouds" shown here) as 3D-shaped orbits. An orbit shows all the positions a planet CAN have, but the planet is still at a single place (although it's moving depending on laws of Nature of course). An electron has a single position, but we have no way to know where because measuring it means interefering with it, which changes its position. The pictures of the clouds were taken with hundreds of electrons. That means it shows all the positions of all the electrons, not all the positions occupied by a single one! The magic of quantum mechanics is its probabilistic nature, but this probabilistic nature still occurs on a massive amount of quantum particle. Or have we proven that a single quantum particle has multiple positions at the same time?

[@ArvinAsh]

Well, this is a great question, and gets at the heart of the central mystery of quantum mechanics. It helps if you don't think of the particle as a little marble. It is a wave. We can't really say that it is in all positions at once. In fact, we can't really say much about the particle other than the possible places we might find it if we measured it. We only know the probabilities of finding it at the location where we measure it. The equations don't tell us anything more.

[@HrishikGhosal]

​@@ArvinAsh what is the volume of the electron cloud?

[@mr.ramchandermishra2181]

I was searching on u tube for such content...finally find a good video....I guess nothing is beyond quantum mechanics nd spirituality....Quantum field has answers to all unsolved mystery...🥰

[@TNTsundar]

Great Video Arvin. Time well spent :)

[@ArvinAsh]

Glad you enjoyed it

[@gameoverwehaveeverypixelco1258]

If I'm looking at this right The wave function is like a person running around a small sphere and jumping at a certain frequency. The amount of jumps and height of the jump is the wave function. This might explains the double slit experiment, in its running and jumping around the sphere part of it gets thru both holes cause it's moving around the sphere so quickly part of it can get thru both. Maybe With a light photon that person running around the sphere Is carrying a torch that is pointed outwards as it moves around the sphere. Shining light in all directions. Maybe the frequency of the jumping and speed gives light colour. Or maybe with a laser the torch is only on on one side of sphere due to the frequency of jumps and speed. So it's highly directional, only on at one state of its running and jumping.

This is supremely high quality stuff. Congratulations.
