    Received most of my physics education in the Schroedinger lecture theatre in Dublin. You possibly should have mentioned his contribution to genetic science. Watson and Crick recognized his work as the foundation for their research and eventual discovery of the double helix as far as I remember.

      Of course, the origin Watson's realization of the double helix DNA structure was from a dream he experienced of two snakes entwining like the caduceus of Hermes. Let's just take a moment -- to realize that reality is weird.

    Gotta love a guy who can break down the beauties and the mind-bending eccentricities of both physics and physicists and also use the word baloney in complete context. It seems that the direction of physics the last fifty years has been to try to bury the unresolved contradictions in nonfalsifiable baloney like infinite multiple universes.

    Dirac showed an equivalence between Schrodinger's and Heisenberg's picture, but what few people noticed was that the Heisenberg picture equations (which look much like Hamiltonian mechanics) are actually weaker than Schrodinger's equation. Even if you solve the equation for the evolution of position/momentum time-dependent operators A(t) in Heisenberg picture, you can't directly extract the wavefunction, thus the probability distribution of the position/momentum of the particle, from it. That's because when you apply the time-dependent operator on a initial state, say A(t)psi(0), what you get is not A(0)psi(t) (what you usually get in Schrodinger's picture when you apply an operator), but instead U*(t)A(0)psi(t) (i.e. the inverse of the time-evolution operator applied to it). So, to get Schrodinger's result, you need to apply U(t) to it, but that requires finding what U(t) concretely is, which exactly means finding a general solution to Schrodinger's equation. I.e., even if you solve the Heisenberg equations you'd need to solve Schrodinger's equation, so it is a weaker theory. That's why Schrodinger's picture is more fundamental

    I like how you told that he had the insight into wave equation while on holiday with his lover (7:20). This makes sense to me. As an EE micro-chip designer, I woke up one morning with a lover, and thought of a new way to construct Programmable Logic Arrays (PLAs) using CMOS elements (FETs). My evidence is empirical and anecdotal, but I suggest that sex enhances creativity.

    Thanks for this new format of shortly introducing important physicists. I like it very much!
    An interesting point to me was the fact, that Schrödinger did not believe in the probabalistic interpretation of the wave function. When I first heard about that in school years ago, I came very fast to the conclustion, that this sounds like a rediculous statement on the level of a fundamental theory. Until today my opinion on that did not change.
    A funny anecdote I experienced, when I recently explained to a friend, who is not familiar with physics, that while measuring the physical state of a system, the wave function breakes down to a random (nearly) classic state and that it is (due to modern view) fundamentally not understandable, which state will appear. He startet laughing and said: "I just imagine a man coming home late to his wife. She is asking, where he has been and his answer is: This is fundamentally not understandable." xD I have found it interesting that also to people who are not involved to physics the probability interpretation sounds somehow unreliable.
    My biggest criticism on the probability interpretation would be that the measurement process, that is supposed to be probaballistic, can in principle not be described by the equation of motion of the theory, since it is a deterministic equation. Therefore the theory is not complete/consistent. I cannot understand why no physicist today seams to care in any way on this huge problem within the consistency of this whole concept.
    Well nearly no physicist ... it is calming to hear that at least the founders of the concept did care xD So thanks a lot for the video!:)

    What do you think Schrodinger's Wave Equation is waving?
    He states in his paper that he is JUST using waves and has nothing to do with material point particles. It is CERTAIN that Schrodinger was not building a statistical/probabilistic equation. His equation gave good answers for the spectral line frequencies, intensities, and Stark Effect polarization (without ANY need to invoke a probability or statistical explanation).

    Schrodinger's Cat - is no longer valid. As we now accept the existence of the "Multiverse" which instantly negates "Super Position" because that would only be relative to the so called Universe at the time of his writing this.
    This now punches above the concept that if the Multiverse is in effect real, then you would have to shift from "Super Position" up a gear to being "Hyper Position" which would only be the next logical step to take at this point. However mathematically hyper position would have to take the state of 0 and 1, up another level to, which for me would make sense to snatch 0 - 9. This then gets problematic because we cannot get our heads around the introduction of all the other numbers. Which Hyper Position is all about so where do? Or how do we get to use these other numbers and is it only limited to 0-9 or is it 0-360 degrees, which becomes mind boggling.
    My gut instinct is that it has always be 360 and there's the magic number of 9 in all of it which is why Tesla was going on about 3, 6, 9, being the divine numbers The nucleus of an atom remains in spin, the spin is 360 degrees, and hence why 0, and 1. is obsolete in. Because this new level of physics introduces not just spin, or phase rotation, but goes further to explain entanglement which many of us have been only wondering about.
    A ball of string could simply explain entanglement and the string theory then has credence automatically.
    This then throws up other issues which we haven't even considered and I for one have been grappling with Black Holes, and White Holes, and their specific roles in the Cosmos, and have come up with the theory which is that they are no more than simple elevators to allow us to go up and down the levels of a "Multiverse" if you pictured an onion and you cut through it, it would have layers and layers. The multiverse operates similarly.

He stirred my interest (which I retain today) by telling us the History. QM is still not a theory (it lacks an explanation) since it only has interpretations, some of which are stupid (like many worlds). The interpretations are just ways of getting around gaps - Schrodinger was right. What we need is a deeply penetrating brain - like Einstein's, to fill the gaps.
