      Well that’s not exactly what he said. The strong nuclear force is still the strong force, but it is interaction between white particles due to them only being white on average, but fluctuating around that. It’s just like the Van der Waals force is really still the electromagnetic force, where charge neutral atoms are attracted because the distribution of charges fluctuates around the average

      ATOM.
      Atom = electron (active) + proton (passive). In simple atom, 99.9% of the space is empty,
      because the distance between electron and proton is 10^-10 m. But if one electron tied
      two protons, then the distance is 10^15 m. (closer to each other by as much as
      five orders of magnitude). The more complex the atom, the shorter the distance
      and its outer space tends to zero, while the inner field increases and becomes nuclear.
      All interactions (EM, nuclear, weak) are the result of the connection between electrons
      and protons and depend on the distance (and conditions) of interaction. These
      interactions obey Pauli's law: "There can be only one electron in an atom: simple or complex."

    Just for perspective, a proton weighs approximately 3.68x10^-27 pounds.
    20lbs of force pushing against this mass is about 5.42×10^27 times the mass of the proton.
    That's 5.42 _octillion_ times the mass of the proton pushing against it.
    The mass of the Earth is approximately 1.3 x 10^25 pounds.
    Imagine a person weighs 130 pounds (1.3 x 10^2)
    The forces pushing the proton are roughly equivalent to having 10,000 times the weight of the Earth pushing against a person. It's mind-boggling how much energy is contained in the nucleus. It's no surprise that nuclear reactions release so much energy.
    (In this example, I'm using pounds but in KG or grams the ratios would still be the same.)

    This is a great explanation, thank you Arvin. :)
    The question this leaves me with is why a nucleus only tends to be stable with a mixture of protons and neutrons.
    It's like there's a "sweet spot" in the ratio of how many protons and neutrons can make a stable nucleus for any given proton count, with a handful of less and less stable isotopes surrounding that preferred ratio, and then if the ratio is too far off the nucleus just isn't going to form in the first place.

    • @Mernom

It is the reason, of course, that nuclear fission, the splitting of the atom, releases the greatest energy known to humanity. It is still mind-blowing that everything, in the world around us, and also ourselves, we are all atomic matter, literally made of atoms!

    @jamesbond_007 2 года назад +4

    This is GREAT! Thanks for explaining this so clearly Arvin! After decades of thinking I understood this stuff, my eyes are finally opened that the strong force != strong nuclear force, and now I understand what mesons are for (at least one of their uses). I always suspected there was leftover (residual) strong force, and posited that it may be responsible for gravitational attraction. And I never knew that the net color charge neutrality was a requirement. And, I thought the gluon flux tube would continue to be reinforced by the creation of more gluons -- I did not know that quarks could appear from the separation energy trying to pull a quart out of a nucleon. It's an interesting parallel between the strong force keeping things together because the color charge is constantly changing within the nucleon, and the strong nuclear force keeping nucleons together by an analogous mechanism of meson exchange.

    Thanks for another great video. One of the things that I have never been able to wrap my head around is why neutrons decay into protons 14-15 minutes after they leave a nucleus and yet the proton will essential last for ever (at least as far as we know)? What is going on in a nucleus that allows neutrons to last essentially forever like a proton, that changes once they are free? I have read numerous answers but they tend to just gloss over it or go into deep math and gobbledygook, can you give a very high level explanation?

    • @ArvinAsh
      @ArvinAsh  2 года назад +26

      That's a great question which gets into quite complex QCD. But let me attempt to answer that in two way. The simplest answer is that a free neutron has more energy stored up in mass than does a proton plus an electron plus an electron antineutrino, which is what the neutrino decays into. A neutron, like all processes in nature, is always tending towards its lowest energy state, and so the lower energy state of the free neutron is to be in the form of a proton, electron and antineutrino. A bound neutron actually has slightly less mass than a free neutron. It becomes more stable in nucleus partly because of the mechanism I described in the video, which is due to the color charge interaction between nucleons.
      Here is the above stated in a slightly different way by another contributor: There is a subtle difference between the binding energy of one up and two down quarks as compared to the configuration of two up and one down quark. As a result, mass of a neutron is slightly higher than that of a proton so a free neutron “tries” to drop to this bigger binding energy configuration with emission of electron and antineutrino. The situation becomes more complicated in the case of a nucleus where inter nucleon interactions enter the game, so some configurations of neutrons and protons become stable.

      ​@@prich0382 Here we go again. A lot of other people have said the same thing in the comments. And Arvin has replied to many of them explaining why we call gravity a force nevertheless. To save you the trouble of searching through the comments for his explanation, I'm copying and pasting his reply below:

      In physics, every force can be described as a gauge theory, which is a form of geometry. Gravity is unique among gauge theories because it is universal - it applies to everything. This is different than electromagnetism for example, because the gauge theory, or geometry describing EM, applies only to charged particles. This leads to interpretations by people who may want to impress you as "gravity is pure geometry." But it is still a force. Stand on a scale, look at what the scale says - 180 lbs? That's a force. Drop a weight on your foot (don't actually do this). What do you feel? That's a force.
      Furthermore, we know that General Relativity is incomplete. GR breaks down at quantum scales. Most physicists believe that a more complete theory of gravity, which would also explain its mechanism as quantum scales, would show gravity to be no different than the other three forces. And so gravity is typically referred to as the "force" by nearly all physicists.

      ​@@ivoryas1696 Arvin has uploaded several videos about the Higgs Boson (which includes the related Higgs Field and Higgs Mechanism). As have several others. You probably remember: The Higgs Boson - dubbed the _God Particle_ - was a big deal a decade ago, though now it's just another boson in the Standard Model.
      In short, all the particles of the Standard Model-except photons and gluons-have mass because of the Higgs Boson, Higgs Field, and Higgs Mechanism. Without Higgs, they would be massless and flying around at the speed of light.
      That's why I consider it as one of the fundamental interactions, alongside Strong, Weak, Electromagnetism, and Gravity.
      Note that the photons and gluons don't interact with the Higgs field. Consequently they are massless, and do fly around at the speed of light.
      However, the mass due to Higgs is only about 1% of the mass of the atoms and molecules that make up everyday matter. The remaining mass is due to the Strong Force. When the quarks are held together by the gluons to form protons and neutrons, and those in turn are held together by the various mesons to form atomic nuclei, all that confined energy manifests as mass.

    1. You describe the strong force between quarks and the strong nuclear force between protons and neutrons as two different forces. Why do we not consider that this makes 5 fundamental forces (Strong, nuclear, weak, EM, gravity) rather than 4?
    2. Why do quark/anti-quark interactions neutralize rather than annihilate like other matter/anti-matter interactions?

    1. There's a distinction between "the strong force" vs "the strong nuclear force".
    2. 12:53 imperfect neutrality. (I have to re-watch to understand under what condition this imperfect neutrality occurs.)

    • @alwaysdisputin9930
      @alwaysdisputin9930 2 года назад +1

      Veritasium's video 'Your Mass is NOT From the Higgs Boson' says imperfect neutrality is due to quantum fluctuations. I think maybe what's happening is the gluon field is constantly changing with particles popping into & out of existence. The fluctuations cause the neutron/proton to lose it's whiteness which it hates & so it immediately fires gluons to change the colour in order to restore whiteness but this changes the colour elsewhere & so it's like when I do a Rubiks cube: I do 1 side but it messes up the other side. This leads to a billion gluons get fired all over the place & the energy from these gluons gives everything mass like if you have (this is from PBS:) a box full of particles bouncing around & you try & push the box but as you push a load of particles strike the inside wall of the box & this makes it really hard to push the box.

      ATOM.
      Atom = electron (active) + proton (passive). In simple atom, 99.9% of the space is empty,
      because the distance between electron and proton is 10^-10 m. But if one electron tied
      two protons, then the distance is 10^15 m. (closer to each other by as much as
      five orders of magnitude). The more complex the atom, the shorter the distance
      and its outer space tends to zero, while the inner field increases and becomes nuclear.
      All interactions (EM, nuclear, weak) are the result of the connection between electrons
      and protons and depend on the distance (and conditions) of interaction. These
      interactions obey Pauli's law: "There can be only one electron in an atom: simple or complex."

    Actually, the strong force holds quarts together, and it’s known exactly. The same is true for an atom and the electromagnetic force. The residual force is what holds nucleons together analogous to the residual of the electromagnetic force which holds atoms together forming molecules (chemistry). It’s a very complicated force which is still not exactly known. Now I do research in quantum chemistry, where we can calculate the interaction between atoms (essentially) exactly. The same framework needs to be attempted for nuclear interaction (lattice QCD is, but it’s an extremely hard problem)

      The 2 protons and 2 neutrons of a helium nucleus are packet pretty tightly. Makes me wonder if the flux tubes within each nucleon work like a subatomic version of the bonding orbitals between two atoms? In other words - in a water molecule, we can see the difference between how an H is connected to an O within the molecule itself (sp3 overlap with s to create a molecular orbital where the bonding electrons can reside in a lower energy state than if they were not bonded) vs. how H is connected to an O of a neighboring water molecule through hydrogen bonding. There appears to be a distinct difference in the two types of connections with Hydrogen bonding being the weaker of the two. And when we put enough heat energy into a pot of water - the weaker hydrogen bonds will break and the stronger molecular orbital bonds will stay intact and the boiling water will send off individual units of intact H2O molecules. So an H will feel the difference between its connection to an O in its own molecule vs its connection to an O of a neighboring molecule.
      So given the close proximity of a down quark in a proton to one of its own up quarks and a similar proximity of that same down quark to the up quark of the neutron right next door - how does it know to gluon flux tube with one and not the other and to meson exchange with the other but not flux tube? Is there a distinct difference "felt" by that down quark (much like the H in the water molecule) or in reality is it more like a molecular resonance structure where they diffuse out equally the gluon and meson interactions and form an energy equivalent grid much like how a resonance structure in an SO2 molecule doesn't favor one S-O bond over the other and we have 1 1/2 bond for each connection?

    10:30 to 11:11 diagram shows how a proton and a neutron interact with each other via the exchange of mesons anda again mesons are a combination of a quark and antiquark pair - we have a single proton up and a single neuton down at the bottom and time flows from left to right - keep in mind that colors must always be conserved: that is the 3 colors inside a proton or a neutron must be a combination of RED, BLUE and GREEN which combine to make a neutral color charge; let me clarify again that this is the same way that optical colors combine to make white color - to you color charge is just a METAPHOR to you
    From above diagram can say that you need of an electron to count with a NEUTRON due that with just the proton the neutron can not be at all- the neutron is the made from a proton and a neutron.
    If a quark and antiquark combine they just will cancel EACH OTHER at the instant.
    There is no cicle flow just left to right same as Penrose diagram wich is bottom to up side.
    RED and GREEN colors are PRIMARY colors while GREEN is a combination of YELLOW and BLUE so green is a SECONDARY color and still if you combine the 3 they will as well cancel each other.
    RED,GREEN and BLUE do make WHITE color in a television but not in real life - In real life red, yellow and blue form the white one and whene this 4 are brocken a rainbow is formed.

According to meson theory of neuclear forces, meson carrying no carge, and positive change as well as negative charge and they are converted into proton and due to proton-proton interaction energy is loss.... this is also the main reason why nucleus of atoms are able to stay together.

      I believe nucleons create mesons because they are highly energized, which is what "causes" most of the mass(e=mcc or e/cc=m) which is higher than an electron. Since they are so energized, bouncing around, sometimes it leads to stretching/mesons.
      BTW, i believe that Neutrons switch into Protons and back regularly by the exchange of mesons too.
      Also nucleon is not so simple as shown in the diagrams, it is more of a constantly changing stew of moving gluons, mesons, quarks and anti quarks all intermingled and changing constantly.

Or was this another simplification so that you didn't make people wonder about "where is the force of gravity"?
    Just curious.

    • @ArvinAsh
      @ArvinAsh  2 года назад +11

      In physics, every force can be described as a gauge theory, which is a form of geometry. Gravity is unique among gauge theories because it is universal - it applies to everything. This is different than electromagnetism for example, because the gauge theory, or geometry describing EM, applies only to charged particles. This leads to interpretations by people who may want to impress you as "gravity is pure geometry." But it is still a force. Stand on a scale, look at what the scale says - 180 lbs? That's a force. Drop a weight on your foot (don't actually do this). What do you feel? That's a force.
      Furthermore, we know that General Relativity is incomplete. GR breaks down at quantum scales. Most physicists believe that a more complete theory of gravity, which would also explain its mechanism as quantum scales, would show gravity to be no different than the other three forces. And so gravity is typically referred to as the "force" by nearly all physicists.

    Arvin and that Aussie are my Go-To's when I want to know more about science and the universe. Arvin's so good, they named a tray after him, the Ash Tray.

      Definitely not expecting to have such an Interaction on a physics channel, so I'll just leave like this: I hope whatever issues you're clearly dealing with eat you up until you mercifully end it all by downing a bottle full of your antidepressants.

    The amazing thing about all this is that as you "drill down" to what might be imaged to be a simpler world with fundamental partials, the clarity afforded by all this is not simpler or, "fundamental." It is more and more complex and not simpler and simpler. As I move to a greater understanding of all of this these fields and forces are incredibly complex, and nothing is getting simpler or more fundamental.
