Hey everyone, thanks for checking out this video! :) Just wanted to pin a couple of minor corrections here, based on your feedback: 1) I should have put “keV” instead of “KeV”. It’s like how kilogram is kg, not Kg. 2) I should have clarified that typically (Laplacian) ~ (d/dt) is called the heat equation or diffusion equation, whereas the term “wave equation” typically connotes (Laplacian) ~ (d2/dt2). *However*, that’s because we often use real-valued functions; when working with complex-valued functions, (Laplacian) ~ (d/dt) does indeed allow for wave solutions, because of the phase degree of freedom in the complex plane. The plane waves shown in this video are examples of that. But instead of just saying that S.E. for a free particle is a wave equation, I should have talked briefly about how the first time derivative requires that psi be complex, at which point this thing that looks like diffusion can actually get wavy. I hope that explanation clears things up. Please let me know if you have any more corrections for this video. I’m trying to always get better over time! :)

The Schrodinger equation is used to make predictions about the behaviour of matter and energy -- a syntropic process, teleological. Making predictions to track targets, goals and objectives is a syntropic process -- teleological. Teleological physics (syntropy) is dual to non teleological physics (entropy). Syntropy (prediction) is dual to increasing entropy -- the 4th law of thermodynamics! Alive is dual to not alive -- the Schrodinger's cat superposition. Being is dual to non being creates becoming -- Plato's cat. Thesis (alive, being) is dual to anti-thesis (not alive, non being) creates the converging thesis or synthesis (becoming) -- the time independent Hegelian dialectic or Hegel's cat (Fichte's cat). Schrodinger's cat is based upon Hegel's cat and he stole it from Plato (Socrates). The scientific method of asking primary questions to get answers is based upon the Socratic dialectic, which is also the Hegelian dialectic. Questions are dual to answers. "Philosophy is dead" -- Stephen Hawking. Stephen Hawking accepted the Schrodinger's car metaphor which is based upon metaphysics or philosophy, hence metaphysics is allowed in physics.

Can you explain what exactly means by "particle has slower all oscillating things"? Exact experimental observations, pls. While concept of asymptotic E(p) curve fits well with my understanding of reality, I cant get rid of feeling that mass increase and time slow might be some correct mathematical backside of wrongly interpreted phenomena.

We’ll get a glimpse of that while looking at it the differences between Klein-Gordon and Dirac. I’ll also do a vid on the Proca equation, not sure whether it’ll be before or after hydrogen part 3. But then we’ll have seen relativistic scalar, spinor, and vector fields. At that point it’ll be natural to get into Wigner’s classification, and we can start building toward the idea that all the particles are irreducible representations of the Poincaré group - that’s where the answer to your question is ultimately found.

Much that most in this video is right on-the-spot, there is a tiny detail that is not. In the metric system, all the dividing prefixes use a lowercase letter: d for deci-, c for centi-, m for milli-, etc. And, all the multiplying prefixes, an uppercase letter: D for deca-, H for hecto-, ... and K for kilo-. But it is not KeV, Km, or Kg that are written on the graphics in the video, but keV, km, and kg instead. A little detail but it should be corrected. Anyway, thanks for the video.

For real-valued functions, I totally agree. But for complex-valued functions, the first time derivative allows for wave solutions because of the phase degree of freedom in the complex plane. I should have clarified that in the video, because you’re right that typically “wave equation” connotes 2nd order in time.

Honestly I’m not sure about a book that focuses on graphical intuition. Unfortunately most of the physics books I know of are pretty dense with equations. But one book that stands out is Introduction to Elementary Particles, by Griffiths. He writes with such wonderful prose that the ideas become much more accessible, and there’s a good number of insightful figures in there too. It’s one of my favorite books of all time. If you’re already familiar with Maxwell’s equations and elementary optics, you’ll have a good mathematical foundation for learning the topics presented in that book.

I suggest you animate the right triangle showing how the mc^2 side stays constant while the pc side and the hypotenuse E change accordingly going from newtonian regime to ultra-relativistic to a massless particle (photon) with E = pc.

A nice didactic exercise Richard. I would say that from a top down view, which the physics student must develop in due course, the concise point IS made by about minute 4 when you indicate that the time operator is first order while the space operator is second. This only shows that the S equation is not "obviously covariant" , but neither are the nineteenth century Maxwell equations, although they turned out to be be so to the surprise of early writers. I think that a very important point missed is that there is no scale factor to the S. equation insofar as velocity, such as c, though h-bar appears to set a size scale. That c must appear in the relativistic kinematic equation you later display, and in the "SI version" of the KG relation, is key, and is roughly how any material particle is "aware" of a universal speed limit. best regards, D.

Well if it makes you feel better, this subject took many years for the geniuses of the world to figure out! Btw funnily enough, Schrodinger came up with a relativistic wave equation (that we now know as the Klein-Gordon equation), before Klein and Gordon. But Schrodinger, genius that he was, realized that the Klein-Gordon equation didn’t give the correct fine structure for the hydrogen energy eigenstates, so he fell back on his nonrelativistic equation since at least it was a very good approximation. Then Klein and Gordon published on the relativistic Schrodinger equation (which is what it’s sometimes called), so they got the credit. Problem is, KG predicted negative probability currents in some circumstances, and also requires a time derivative term as boundary conditions (these things are related). This went against the spirit of quantum mechanics at the time, which prompted Dirac to break geometry and take the square root of the energy-momentum-mass equation, thereby giving us a mathematical basis for interpreting spin and antimatter. We’ll go through that process in the upcoming videos.

Hi! I love your videos. I was wondering if you could give me some insight on whether the path of least action influences the evolution of an electron in a 1D potential.
@RichBehiel
@RichBehiel 11 ай бұрын
Yes, the principle of least action applies universally. Quantum physics can be formulated concisely by defining the Lagrangian density of a field, then applying the principle of least action to derive field equations as the conditions that minimize the action when integrating the Lagrangian density over spacetime. That’s another way of deriving the Schrodinger equation (although the Lagrangian approach is often used more in QFT, for the Klein-Gordon, Dirac, or Proca equations). That’s all coherent with the kind of quantum physics where we start with the Schrodinger equation and calculate wavefunctions. But it’s much easier to calculate wavefunctions than to work with path integrals, for example. So, often the principle of least action is invoked only implicitly, as something that gives rise to the conceptual machinery that we take for granted.

There is no self-consistent quantum theory of the electromagnetic field. There was none in the classical case, either, we are just not talking about the problems very much when we are teaching classical electromagnetism.

Actually I recognize the Schrodinger equation more as a heat equation than a wave equation. The model in my head had the wave equation with a second time derivative as well as a second spatial derivative but I sort of see how complex numbers might make the Schrodinger equation a wave equation too. I had to think about that one though and still do.

You’re right, the Schrödinger equation is kind of an ambiguous mix of both. I should have clarified that in the video. If psi were real, then it would be a heat equation for sure. Because the rate of change of the field would equal the laplacian, so the thing would diffuse out and settle down over time. But the complex phase and the i in the derivative, the SE has wave solutions because of the way the laplacian of the real part affects the imaginary part, etc., and that can go on waving forever. That’s actually why the SE must have a complex-valued psi.

Great question! If psi were real-valued, then yes, because the rate of change would be proportional to the laplacian, so the wavefunction would flatten out and then stop moving. But since psi is complex, the phase provides a degree of freedom, which accommodates wavy solutions. You bring up a good point here. That’s actually why the Schrödinger equation has to be complex-valued. I should have clarified that in the video tbh.

Ocean waves with longer periods carry more energy and travel faster. In contrast, light maintains a constant speed; the shorter the period, the more energy it exhibits during collapse. Therefore, it cannot be described as a wave, but an alternative term may be utilized.
@RichBehiel
@RichBehiel 11 ай бұрын
Good point! It would certainly be wrong to say that light is the same as an ocean wave. Whether the term “wave” is broad enough to encompass all wavy things, is a matter of semantics. The great thing about math is that the equations specify the behavior of the waves, so there’s no semantic ambiguity when doing calculations.

@14:30 We have pushed matter really, really hard and can't exceed c. *But you could look at an external push like that in that terms of Doppler Shift, and see that as v approaches c, the force of the push approaches zero. This is like pushing a car with just your own body: When it is stationary, you can brace yourself and push really hard, but when the car is going as fast as you can run, the force of your push goes to zero. So have we **_really_** pushed particles that hard? **_No!_* We are pushing the particles with electromagnetic waves travelling lengthwise down waveguides, so of course the particles cannot go any faster than the waves pushing them. Now, if the waves were propagating _transverse_ to particle velocity, we might see something quite different. In that case, _there is _*_no limit_*_ to the speed at which the wave crests will appear to propagate sideways, from the perspective of the particle!_ At this point, somebody will probably say something to the effect of 'But in the reference frame of the particle, electromagnetic waves always travel at exactly the speed of light.' Yes... and no. This gets into murky territory, where the *assumptions behind our theories* do not necessarily hold true, and we must resort to experiments to determine *what nature really says.*
@RichBehiel
@RichBehiel 11 ай бұрын
I see where you’re coming from, and it’s an interesting thought experiment! The only thing is, the energy of the electron increases and increases the more it’s pushed. In the example of pushing a car at running speed, there will come a point when the speed stops increasing, but so too will the kinetic energy stop increasing. So if the problem is just that light is not fast enough to push something faster than the speed of light, then we would expect there to be not only a speed limit, but also a kinetic energy limit, of about 255.5 keV in the case of an electron. The fact that electrons have been accelerated to half a million times that energy limit, is an indication that the electrons do indeed continue to be pushed with a tremendous amount of force.

If the wavefunction were real-valued then yes, you’d need a second-order derivative in time, since a first-order time derivative being proportional to the Laplacian would just settle and diffuse (heat equation). But when psi is complex-valued, a first-order time derivative being proportional to the Laplacian does indeed allow for plane wave solutions, due to the complex number’s ability to rotate in the complex plane.

Hi Richard, that was great! But I'm wondering, could we not just bung a factor of gamma on the momentum and walk away with a relativistic Schrodinger equation? I'm sure they would have tried this and failed and then switched to Dirac, but ?? thanks D
@RichBehiel
@RichBehiel 11 ай бұрын
Great question! I’ve never thought about that. Hmm. Well, gamma and momentum are interrelated, so if we put in a factor of gamma, it would implicitly be a function of momentum, so then momentum would be nonlinear. At that point we might as well go with Klein-Gordon (which btw is sometimes called the relativistic Schrodinger equation, because Schrodinger came up with it first, but was unsatisfied with it because it didn’t account for the fine structure of the hydrogen eigenstates). Dirac fixed that problem by linearizing the energy and momentum terms, which brought spin and antimatter into the equation. Anyway, another interesting feature of relativistic waves is that their phase oscillates, rapidly, even when the particle’s momentum is zero. The mc^2 rest energy term is twice the Newtonian momentum of a particle traveling at the speed of light, for a sense of perspective. So relativistic waves are oscillating super fast, while the Schrodinger equation for a particle at rest is just a constant, inert, lifeless complex number. So even far from the speed of light, there are qualitative differences between the two models.
