Great job!

We know that the normalization condition has to be obeyed, but how do we come to the conclusion that \phi and its \conjuagte have to approach 0 as the \lim\x tends to positive/negative infinity? Can you please explain the same.

But isn't the LHS of the schrodingers eqns a momentum operator on psi? How does that translate to total energy?

The wave. Function of particles bass no physical meaning.There is no waving here.However remember that particles are prophages as if they are waves.Hence the square of the wave function gives the probability of finding the electron at that point.But the wave function has no Physical meaning.

you are Rock sir, You helped me a lot in my Phsics course. Will You please make lectures on Perterbation theory and WKB approximation.

An example is the function f(x) = n on the interval [n, n+1/n^4). We then see that \int |f(x)|^2 dx = \sum_{n > 0} n^2/n^4, which is finite.

Thank you so much man I really like your lectures... And your complex variable course helped me pass my mathematical foundations course... Can you please try complete qm by May because i'd have an applied physics test then and your videos are the best study source I have 🙂

Perhaps, one would argue that state functions that do not have \lim_{ |x| \to \infty } f(x) = 0 are not physical.

Thank you.

Just a remark, just because \psi is square integrable, that does not mean that it converges to zero. It means that if the function is uniformly continuous, but otherwise not.

Excellent, but is the beginning of a series? Where is the next. Or was this the end. Hope not.

Great video, only one issue. In 10:52 where you substitute the partial time derivative by solving for it using Schröndiger equation. To get it from the equation we multiply by 1/ih and 1/-ih for the complex conjugate of Ψ (Ψ*). Βut it doesn't seem quite right. Can you please tell me what I'm missing? Thanks. Also consider where h=h-bar since my keyboard doesn't have that

Your video is clear cut as always and direct.

Einstein would disagree with all of this !

psi=e^(ix^5)/(x^2+1) violates the last part of your proof. Despite having an absolutely convergent integral with absolute value going to zero, the limit of the boundary conditions is non-zero.

What are the parameters that we obtain from the Schrodinger equation?

im gonna request a video on Hamiltonian systems :) Would be nice if you could give examples like how Kepler problem is a hamiltonian system and how the wave function is too.

This f is not continuous, but one can (using smooth step functions instead of normal step function) find a smooth function that has the property that f(x) converges to infinity as x goes to infinity but is still square integrable.

Do you think it is logical that if the future is unfolding relative to the atoms, if we look down at the individual atoms we will find probability? This is an invitation to see a theory on the nature of time! In this theory we have an emergent uncertain future continuously coming into existence relative to the spontaneous absorption and emission of photon energy. Within such a process the wave particle duality of light and matter in the form of electrons is forming a blank canvas that we can interact with forming the possible into the actual! The future is unfolding with each photon electron coupling or dipole moment relative to the atoms of the periodic table and the individual wavelengths of the electromagnetic spectrum. As part of a universal process of energy exchange that forms the ever changing world of our everyday life the ‘past’ has gone forever. At the smallest scale of this process the ‘past’ is represented by anti-matter annihilation with the symmetry between matter and anti-matter representing the symmetry between the future and the past as the future unfolds photon by photon. In such a theory the mathematics of quantum mechanics represents the physics of ‘time’ with the classical physics of Newton representing processes over a period of time, as in Newton’s differential equations. In my videos I explain how this process is relative to temperature and the phase changes of matter.

Although I only know basics physics, the explanation provided in this video gave a real understanding of the Schrodinger equation in less than 15 minutes.  I am simply left speechless.  Thank you so much for such an insightful video and for your genuine desire pass on your knowledge.

Please can somebody answer this?: We need the normalisation condition to be finite, therefore Ψ approaches zero and the time derivative of the normalisation condition is 0. But in order to assume that the normalisation condition holds true, we first need to prove that the time derivative is zero? HOW can we prove something, using the result we want from the proof which hasn't been proven? It contradicts. We can't assume the normalisation condition holds true and us finite so that Ψ------>0 when we haven't yet proven it works for all values of t.
