What is The Schrödinger Equation, Exactly?

[@upandatom]

You can learn quantum mechanics with brilliant if you like brilliant.org/upandatom/ Also, when I was 10 I asked my older brother to teach me to skateboard. The first thing he tried to teach me was to start moving from a stationary position. He had me stand on the back of the board with one foot so it tilted upwards, and then slam my other foot down at the front of the board and apparently that was meant to make it move forward. So on my first try I slammed my foot down too hard, the board slid out from under me as I was propelled forward and my face hit the hard pavement. I never skated again.

Interesting... sorry to hear about the face plant! But somehow I'm connecting it to the final bit of this blog post I just read yesterday: blog.interviewing.io/we-built-voice-modulation-to-mask-gender-in-technical-interviews-heres-what-happened/ ... relevant??? Also, I just want to let you know that I find the brilliant.org plugs jarring, and wish they either weren't there, or were more subtle, or something. I don't expect a change necessarily, just... thought I'd share one viewer's take. I pay for the ad-free version of KZbin, and the brilliant stuff feels like advertising... which I presume it is? :) ... and perhaps you genuinely want to support what they're doing, and that's fine, just... I dunno, letting you know. :)

[@upandatom]

Thank you for letting me know about how the brilliant ad sounded. It's my very first sponsored video so I'm still getting the hang of it. I do like brilliant a lot, but I'm disappointed to hear it stunned you. I'll work on making the ad reads more subtle or giving more warning or something.

Same for me, even if I have gotten my physics degree many years ago. Now I'm reading in a very relaxed mood mathematical papers and physics books. When I don't understand them I come back later, without pressure. Particle physics or General Relativity are indeed somewhat hard like pure mathematics.

[@gristly_knuckle]

I'm bad at math. I disagree that the Shrodinger Equation describes real meaning. It can't be performed. Everyone I don't see is really somewhere, and accidents aren't happening. In the same way a "quantum particle" must really have a position and a velocity, even if you can't see it. Perhaps every "quantum particle" has a corresponding "Satan square" which must have a position and velocity because it is a real object. It collapses into a Satan square only in your imagination.

[@PartialViewmusic]

@L. Kärkkäinen Well, that honestly is not a proper derivation of the Schrödinger equation. It assumes the time dependent wave function has a form as \Psi(x,t)=e^{i(kx-\omega t)} (This is latex code, plug it into an interpreter to more clearly see what I mean). This is called an ansatz and it works in order to derive an equation. However, there is no proper, real and strict mathematical proof of the Schrödinger Equation. Schrödinger simply postulated the equation. And so far it works, me as a third year nuclear physics student use it every other week to compute wave functions in the shell model of a nucleus. And it works and can be experimentally shown to work. But there is no proof. Pure mathematicians despise us physicists for using it since they always require proofs haha

Yes. That's exactly what it means. In the real world, there is no way to create an infinite potential capable of forcing the wave function to 0 at the boundaries of the box (much less the entire universe outside the box, which is what the problem sets up). What's amazing is that despite the fact that this example is non-physical, it can be used to produce excellent approximations of real experiments.

Yeah well ! according to Shroedinger your electron could be located ANYWHERE in the universe - and it would still belong to the atom to which it is said to belong.

Hi Peter, you would know either where it went approximately or where it is now, not both 😉. You choose.

Very well done Jade. Without overly extending the explanation as is and thus making it less comprehensible, I'd try to include brief allusions to the following with possibly links to further details:- The wave function itself - how and why it's form was chosen, i.e. why is it complex, what's its relation to Euler's identity, why did it need to be wave-like to begin with etc. A reminder on what k are w are and what they represent in the wave function. A reminder where the de Broglie relation comes from, the matter wavelength relation to momentum and how k fits into that and why. A quick work through the Schrödinger equation derivation you gave the briefest snapshot of - it is very good, clear and concise but may overwhelm those new to it, without an explanation of what is being substituted into where and when. A justification as to why squaring the wave function yields the probability function of finding the electron at each location.

[@ColinMill1]

When I was an undergraduate at Bristol in the early 1970s they thought it would be a good idea for physics and chemistry students to take all the first year courses from both departments. As a consequence we got quantum mechanics from the physicists at 9am and quantum mechanics from the chemists at 10am. Unfortunately the departments clearly never talked to one another and the physicists taught the time-dependent form while the chemists taught the time-independent form with neither of them acknowledging the existence of the other form!. Neither side thought it was a good idea to show that Newtonian mechanics can also be written in the Hamiltonian formalism (which I think should be obligatory to save the inevitable confusion of presenting a new physical concept in a new mathematical wrapper at the same time). Anyway, I guess it did me an indirect favour - on graduation I decided to do research in an area where quantum mechanics wasn't involved and I chose cloud microphysics - perhaps belatedly one of the hottest topics of our time (a back-water, however, in the 1970s)

[@david203]

When the Schrödinger equation is presented in just the right way (the Wigner transform), you can see clearly how it moves from describing QM states in very small isolated systems to describing Newtonian mechanics in large systems immersed in an environment with influences such as temperature and viscosity. This transition to classical mechanics can also be seen by the density matrix transitioning from having off-diagonal elements (the pure quantum states) to being a diagonal matrix (in the classical case).

Also that was the first time (in years of watching videos on the topic) that the reasoning/correlation behind the discrete energy levels and wavelength was made clear

[@anushkakulkarni2238]

She was awesomee ..Professor dave explains this very easily too

[@sushmitagautam5397]

Ma'am didn't know that Learning Quantum Physics is this much Fun.... until I saw ur video. A WONDERFUL TEACHER CAN MAKE ANYTHING INTERESTING. 🙂✌️😇

[@mikes4163]

Well, that's the first time I actually feel I understand a tiny bit about quantum physics - ie, what wave function actually means and it's connection with discrete energy levels. Super video.

[@cristiangamboa2037]

Thank you for explaining this to people like me, who are very interested in physics but have not have the chance to actually study physics in college.

[@paritoshattri672]

Actually its chemistry sis😂

[@sarthakgirdhar2833]

@@paritoshattri672 it's quantum mechanics. Attribute it to any subject, physics or chemistry. But there's something you must know; it's more physics than chemistry. Guess you are in class XI right now.

[@aventador444]

@@paritoshattri672 you do realise chemistry is basically applied physics which is essentially applied maths. At higher levels all 3 subjects merge and there is no longer really much separation between them.

Your enthusiasm made quantum easy.Thanks for such simple explanation 💗💗

You are phenomenal, it makes sense to me now. I couldn't ask for for more.

The Wave function doesnt tell you where the electron is likely yo be. It is the square of the wave function. The Wave function itself has no physical interpretación, and it's not just a detail. It's fundamental.

[@lorrinbarth1969]

Or, the wave function really is an electron and when measured the law of conservation of energy limits that measurement to one place. Otherwise, it would be infinite energy.

[@ajibadelasisi8569]

6 years ago, and your video is still applicable today. Simply legacy 👏. Also, thank you for your project attached to the video. It helped me understand the concept of "particles in a box" more.

You deserve way more subscribers btw our electrons are so cute

[@vsbvsb5872]

Quantum mechanics is not something that can be tamed by everyone....I gave up physics just because of this... But whenever I see your video I feel that even these concepts can also be mastered irrespective of how difficult they are..... That gives a positive energy..... So please keep uploading videos ..... and let your talent give hope to others who think Physics is hopeless for them....🙂🙂🙂👍🏽

[@ChanPrue]

For those of you trying to make it through the derivation, dPsi/dx is a partial derivative, meaning that omega and t are treated as constants. This is often shown as sigmaPsi/sigmax. P.S. Thank you for making a video that shows the math, and doesn't just say "...and that goes beyond the scope of this video"
