   I think that the Schrodinger picture, which is the one that uses the wave function as a probability wave and the probability of one thing happening rather than another, that is a, I think, a misleading way of expressing the theory, though it does express the theory correctly and fully, but it's misleading in that it doesn't include an account of how the outcome comes about. So I favor using the Heisenberg picture, which is the other way around. It takes as fundamental, the observables of a physical system, exactly like classical physics does. And the state is a constant, therefore it doesn't, …

   In the summer of 1925, Verer Heisenberg developed the first consistent theory of quantum mechanics. The paper he wrote is cryptic even for experts. But inside we find four groundbreaking ideas that rewrote the rules of physics. In this video, I will walk you through these ideas, concepts, and calculations to show you exactly how Heisenberg created quantum mechanics. Quantum mechanics was created by Verer Heisenberg in 1925 with the publication of this paper. The content is hard to follow. Some sections lack continuity and some mathematical steps look like magic. The goal of this video is to ch…

   It was so much closer in a way to the things that physicists were comfortable with, that Schrodinger kind of won the day, at least, in that historical period. - Yes, ironic... There are several ironies about that period of about a year when everything happened. One of them is that the Heisenberg picture was originally called matrix mechanics, because Heisenberg expressed it as matrices, but he had never heard of matrices. Matrices were not covered in the mathematics for physics class in his day. - Right. - So other physicists had to tell him, "What you've just invented is matrices." And now I …

   Stability is maintained until a quantum jump occurs, an instantaneous leap between orbits where radiation is emitted or absorbed, governed by the relation E equals HC over lambda. This model provided the ultimate proof by accurately predicting the observed spectral lines of hydrogen. By successfully bridging classical mechanics and the burgeoning quantum realm, Bour's 1913 trilogy replaced chaotic collapse with a precise orderly blueprint of the atom, laying the foundation for modern physics. In 1921, Neils Boore's Institute became the Copenhagen Mecca, the epicenter of a scientific revolution…

   They said there's aspects of light, which is supposed to be a wave, which are particle-like. Einstein said that. There are aspects of particles like electrons that are wave-like. Louis de Broglie, following work by Niels Bohr and others, said that. And this whole thing coalesces almost exactly a hundred years ago in 1925 in the theory of quantum mechanics. And almost right at the same time, two different versions of it came out. Werner Heisenberg had his version called matrix mechanics. Erwin Schrodinger had his version called wave mechanics. They show that they were actually mathematically eq…

   Um so the idea of Heisenberg that is that you could still apply the Hamilton's equations and but only on on matrices which matrices which were non-comitative types of symbols as opposed to the ordinary commutative numbers. But even though uh at that stage you know you had complete replacement of even the mechanical uh laws by new laws of quantum physics. Um Heisenberg and Boore estimated that this type of theory was still an application of the old correspondence principle between classical physics and quantum physics. Here is what B said. The laws of Heisenberg are a precise formulation of the…

   This is the bold conceptual innovation that makes this paper the foundation of modern quantum mechanics. This weird multiplication rule made Heisenberg very uncomfortable. In the paper he wrote this multiplication rule is an almost necessary consequence of the frequency combination rules. He accepted what his theory was telling him but could not make sense of the meaning of these non-commutative objects. After his return from Helgoland, he expressed his concern to Max Bourne. What are these objects that obey these rules? Let me bring back the way the transition amplitudes are combined. Heisenb…

   Inspired by Latenburg, this idea was extended by Henrik Kramers who found a quantum theory of dispersion. Kramers and Max Bourne also discovered a mathematical relation between classical and quantum relations that was crucial for Heisenberg. Let's now dive into Heisenberg's famous paper. The key word is reinterpretation. Historians of science refer to this work as the unon paper. What everyone was searching for during the 1920s was a way to derive quantum equations to replace the equations of classical mechanics. Heisenberg built on the ideas of Einstein, Latenburg, Kmers, Bore and Bourne to f…

   So this just seemed like a radical departure from how we thought about kinematics, dynamics and probability from before the beginning of modern quantum theory. This is formalized by 1930 in Paul Dak's book um principles of quantum mechanics. Uh I won't tell you how old he was when he wrote that book because it would make everybody really really depressed. He was very very very young. Um and then John Vonoyman followed up two years later um with in the English translation mathematical foundations of quantum mechanics. But they basically told the same story. John vonan told it in a much more mat…

    Other times, as people like Albert Einstein and others began to, to find, they really, really had to describe aspects of light as if it was a collection of particles that traveled almost like miniature billiard balls. NARRATOR: Ultimately, the answer was a new kind of physics, quantum mechanics, which included an amalgam of ideas about both particles and waves. Its earliest formulation dates back roughly 100 years. This 1927 conference in Brussels is where the world's leading physicists met to discuss the newly formed theory. (people talking in background) NARRATOR: And there was a lot to disc…
