Summary:
Ask 10 physicists what a particle is: you'll get 10 different answers. Quantum mechanics showed via the Schrodinger equation, that quantum objects are not particles but waves smeared out in space, until the moment we measure it. They are described by a mathematical term called a wave-function. It doesn’t tell us where a particle is, but only the probability of where it might be if we measured it.
Is a particle a collapsed wave function? Maybe, but this is not a good description because we don’t know what wave function collapse means. Quantum mechanics shows that photons are a wave packet. This wave packet can be looked at as a kind of particle. Something similar can be done for describing other particles too.
The Schrodinger equation does not work when objects travel close to the speed of light. It does not account for special relativity. In the 1930’s scientists like Dirac found a modification that was compatible with special relativity. This led to quantum field theory, or QFT.
In quantum field theory, what we call particles are quantized waves in a field that spreads throughout spacetime. The idea of quantized fields was a necessary step in order to describe objects like photons and other fast moving objects that need to be treated according to special relativity. QFT is nothing but a theoretical framework that unites ideas from classical fields, special relativity and quantum mechanics.
The idea is this: you start with a field or analogously picture yourself a calm sea that stretches throughout all of spacetime. This is an empty field without any particles. Now imagine that there is a wave in the sea, this is a particle in our field. There is however at least one difference between the quantum field and our ocean, our ocean is not quantum.
For our ocean field to be quantum we have two requirements. First, the waves in our sea must have some discrete magnitude. This can be represented by the amplitude or height of the wave, like 1 meter, 2 meters, 3 meters and so on, nothing in between. Each meter corresponds to the number of particles in any one place. The second requirement is that there has to be some minimum energy state at all times. So we will say that the 1-meter waves represent this minimum energy state. This is called the vacuum energy. I
Then each extra meter of amplitude or height is a real particle. We can only create taller waves in increments of whole meters. The minimum aplitude is 1-meter waves. Each extra meter is then a real particle. But we can only create these taller waves if we have enough energy to reach the next meter. If there is not enough energy to reach at least 2 meters, no taller wave is created.
These one meter waves are from the quantum vacuum, they represent the non-empty minimal state. These quantum waves slosh around and, in some places, there might momentarily be enough energy to create a larger 2-meter wave or a particle. But then almost just as quickly as it’s formed, the particle vanishes again in the sea of fluctuations. These are analogous to virtual particles that come in and out of existence all around us, but are undetectable because they last for too short a time.
The quantum field is like the sea - it is the background on which waves appear and disappear. And just like energy can create waves in the sea, energy added to the field generates particles which we can observe.
If you expand this concept to other particles, we have to imagine other seas representing a different field for each fundamental particle that we know of, so there would be a sea representing the field for electrons, field for photons, field for quarks, etc.
What does “fundamental” in the word fundamental particles mean? It means that the particles of the standard model are the smallest particles from which we can construct the world around us. There is nothing, that we know of that is smaller that these fundamental particles are made of.
#quantumfieldtheory
#qft
As of now, the best description for a particle would be something like this:
A fundamental particle is an excitation in a quantum field that is constantly in flux. There are at least as many fields as there are particles in the standard model. Each particle can propagate in its field. The interactions of these fields and exchange of energy results in particle creation and annihilation. In the end, you should remember that this is just all math.

What do the Twistors of Roger Penrose and the Hopf Fibrations of Eric Weinstein and the "Belt Trick" of Paul Dirac have in common? It takes two complete turns to get down the "rabbit hole" (Alpha Funnel 3D--->4D) to produce one twist cycle (Quantum unit).
I stumbled upon this one right after watching your latest vid on neutrinos. Arvin, this has to be one of your top five. Wow! Because you touched upon questions that are close to my heart and made statements that resonated so very well with how I think about things. When you say something like 'but math is just a tool to describe reality' or 'we should not be too confident about quarks being the most fundamental', you so humbly put forward the limitations that we as humans have in describing the physical reality we inhabit. Let me assure you, this is NOT the way they are introducing these beautiful subjects in schools even now. The way things are presented is as if everything is known and we humans have mastered everything. Math is taught as if it is the end all and be all of the world. You made my evening. Cheers and a million thanks for your work.

I never understood before how particles can form momentarily in vacuum space until now. So its actually the chance additive effect of waves combining in the field to produce a virtual particle at a given space-time point. (or words to that effect. Thankyou.

I consider it a matter of interpretation. I don't exclude other ways of considering it. But it comes from the fact that a quantum field is never still, and since it is quantum its properties are not well defined. So sometimes you have extra energy somewhere in the field, and that is what causes the virtual particles. You can imagine this in different ways than additive waves. But it comes from a surplus energy at some point from the field and its unsteady vacuum state.

the extra energy is "old fashion perturbation theory", which Feynman ended. In the path integral approach: an initial state goes to a final state as a sum of all possible paths that conserve energy, momentum, etc: but energy can be negative or arbitrarily large in any sub-vibration, so that's a lot of paths, even if the initial and final states are just the empty vacuum. How that can't be "infinity" every time is a deep question addressed by the renormalization group equation, hopefully AA will make a video on that...the most difficult topic in rQFT.

Elementary particle, like electron, can be understood as a persistent closed flux of energy of electromagnetic oscillatons. Toroidal ring of homogeneous flux with radius r corresponding to reduced Compton wavelength {lambda/(2.pi) } = r. With mass m={h(trans)/c}.{1/r}, mass as a measure of real vacuum inertia to bending of energy flux (bending of Poynting vector). In a given referense frame. Bending {1/r} gives birth to mass. Or not, like for photon with no bending to ring, zero 1/r(infinity) Spherical symmetry of E, B stereosweep to spherical angle 4.pi gives impression of effective "stationary" field , atributed to elementary charge |e-|. In reality just mathematical construct, ratio of on ring centrifugal force in [N] and effective electric intensity E(effective) in [V.m^-1], i.e. N.m/V or J/V = [C]. |e-|={h(trans).c}/{r^2.Eo/(2.efactor)}. Eo/(2.efactor)= E(effectiv)=c.B(effect) r^2.Eo is invariant. So |e-| is invariant. |e-| = h(trans).pi/{pi.r^2.B(effect)}= h(trans).pi/Fio and Fio is magnetic flux quantum, known from superconductivity. Fio=h/(2.|e-|). Its inverse is Josephson constant, ratio of ring angular speed [Hz](energy flux with speed of light) and voltage [V] on a halfring E(effective).r.pi. Exactly like measured. Eo , Bo are estimated from mass density in the toroid. Toroid dimensions from electron magnetic momentum.

The best and simplest explanation about how everything fits together I ever heard. Well done. It got me thinking, the issue is always time. It is time that does not fit. 1.It seems like time does not exist in the quantum realm. 2.A photon experiences no time until interaction. 3.Delayed-choice quantum eraser, backwards in time. 4.Entanglement, time is not an issue. 5.Gravitational time dilation, the presence of mass and energy warp spacetime, mostly time. 6.The rate at which time passes depends on your frame of reference. 7.The universe doesn't care about the speed of light. Then it does not care about time either. The speed of light is constant for all observers, probably because time has nothing to do with it. Time ceases to exist in a black hole, a singularity is just a different form of quantum state. The inexplicably rapid inflation of the universe. As long as the baby universe was in a quantum stat there was no time, except maybe if viewed from the outside or from an another dimension. Conclusion. Time is an emergent phenomenon. You can not measure something without isolating it and interacting with it. Interaction means emergence in time. Any thoughts?

Fantastic. I love what we know. The math can be off-putting, but these demonstrations and explanations pull us novices along the nicely.
The visuals are hard due to the linearity of trying to draw this action, in the particle(?) form the field it would generate(?) would be radial and 360 deg spherical in all direction of its location/mass and travelling with a direction and velocity. Hence the first quantum drawing program is required. Great vid TY sir.

Love from India 😎😎
Great presentation - thank you Arvin! In my humble opinion, quantum field theory is currently the best approach to understanding of reality around us, but maybe it's all taking place in one multi-dimensional quantum field, not multiple fields. Those extra dimensions that we can't observe on our scale, are responsible for behaviors that appear weird to us in our observable three dimensions. In that multi-dimensional field, energy signatures we interpret as various particles propagate simultaneously, a little bit like radio waves of different frequencies propagate through space. Looking at the big picture, the universe is one big quantum field with small scale phenomena building the large scale image. I think the large scale landscape of the quantum field is responsible for behavior of the universe, not some "dark matter" or "dark energy" constructs we've invented. Quantum field does not have to be flat :-)

A fundamental particle is an excitation in a quantum field that is constantly in flux. There are at least as many fields as there are particles in the standard model. Each particle can propagate in its field. The interactions of these fields and exchange of energy results in particle creation and annihilation.

@@jaredf6205 - Wouldn't that be rather "virtual" particles in real fields? There are virtual photons, electrons, etc. but they belong to the electromagnetic field, electron field, etc. The difference is that gauge fields (bosonic fields) act as interactions between the fermionic ("material") fields: for example the electron and the proton (or two electrons, etc.) interact via the electromagnetic field (photon field, which is ironically not electromagnetically charged). As Dr. Gamma explains these fermions have "material" properties, so they can't be in the same place at the same time (unless they have opposite spin or similar, i.e. Pauli's exclusion principle) so the waves shown in the video better reflect the behavior of photons than anything else because they can add to each other in space and time, while electrons (for instance) can't unless in very specific ways (they do add up in time however because the double slit experiment applies to them but not in space).

I just have a lingering question in my head that I'm yet to see explained: I cannot picture how these evermoving waves in these fields, which are dynamic to the core, can form normal objects like a table, for exemple, that stands still, or even animals, that can move or stand still. This is my normal understanding of this: When I stand still the "waves" that form my body, I assume, are vibrating in a tiny space. Does that means that when I move, the energy that constitutes my body excites the fields right next to me, creating new waves, and the ones from where I was, no longer having my "energy", come back to their normal state of vacuum energy, which is instantly excited again by the energy of the waves from the air atoms? And that would mean that you dont have "atoms" per say, you're actually constantly creating and uncreating them while you move through space with the energy of your being. _______________________________________________ Spiritual reverie: And if that is true, dude, I'm a Christian, even if I try really hard not to connect this to the words in the Bible, I just can't. You see, the real name of God is YHWH, the sacred tetragrammaton, which is derived from the words: I am, I was and I will be, depending on the interpretation, or it means the verb "to be" itself. So when God told us that we have a divine spark in us, it means that we are the creation, but also we're literally in a constant act of creation of particles by the mere fact of breathing. It's a crude connection that I just made up right now, but a beautiful one, I think. *sorry for any English mistake, I'm not native.

If 'this' is true then you should be a Hindu. Sadly, it wouldn't matter what the truth is...you're going to find a way to curve fit it to your belief system regardless.
I'm so glad this channel exist. Keep on the good work.
Absolutely love your episodes. You speak to so may of us “lay-humans” about something so incredibly complicated yet convey it in a way easy and beautifully imaginative to understand. That’s genius. When I’ve tried to explain the collapse of the wave function by observation Ive used the 1st person shooter video game analogy. Hear me out, lol. If you think about it, if you look down at yourself right now, all you see of yourself is your limbs and torso. No upper chest, no neck, face. Just like many 1st person video games. What you see in “your reality” is akin to what “your character” sees in his/her reality, (what’s on the screen) (You just see both “real” and virtual realities at once being the controller of this avatar, obviously ) I tell a person to visualize your video game character walking up to a house. The house is now on your screen. You see it as does your make believe avatar. Now, spin your character 180 degrees. Ask “where did the house go”?? It’s there… but it’s not. When the video game character is spun away from the house, the “house” goes back into 0’s and 1’s on a hard drive. Waiting to be pulled up again by the processor being told to do so by a “consciousness.” Thus, in your subjective reality, is what’s behind you “not really particles”? Just a wave of probabilities and until you observe this fief of waves does the particles not need to “exists” until consciousness collapses the wave function? If someone is facing you, the “waves of reality” collapse behind you but ONLY in “their” reality and what’s behind them collapses in YOUR reality?? Is this what’s going on?? Just a pondering
great job luv the information and ur presentation
One of the very few videos that deserves to be put in the favorites list
thank you for a helpful video, I actually answered all the questions I had posted earlier by watching your videos on the higgs field and symmetry breaking, thx!
I mean, I know I’m a smart guy, but man, the amount of concentration it takes to follow this (I don’t have a math or physics background) is exhausting. Profoundly interesting stuff. This will be on my mind for weeks.
This was well-written and illustrated and the narration was clear and enjoyable. A+
Terrific presentation of wave particle duality and explanation of virtual particles. Well done!🤗
Best explanation I have ever seen! Thank you.
Excellent video, as always. Very interesting, informative and worthwhile video.
Thank you dear Arvin. You amazing and your voice is very easy on the ears. ❤
This far the best explanation and visualization of virtual particles. Since 2009, I never understood this better. Viva la Arvin!
First time here, very good stuff! Congrats on the good work.
Really great explanation and visuals. Well done!
this is such a good explanation it gave me chills
I hope to God there are people out there, much smarter than me, watching these same Arvin Ash videos with same awe and unfathomable reverence and that they will make a major leap in the understanding of what reality is.
Thank you. That was great and inspired me to do the course.
Thank u arvin glad to know all the chapters......Awesome teaching superb👏🏻👏🏻
Thank You for this Video, Arvin Ash.
