I didn't understand the whole animation thing, where a conditional wave function was illustrated, along with wave function collapse. I thought that in Bohm theory the great thing was that the universe includes the experiment AND the pointer device, so there IS NO environment. This means that there IS NO wave function collapse at any time. The pointer moves as part of the experiment, and shows the result without any decoherence. No?
That's right, the overall wave function always evolves according to the Schrödinger equation. But when you want to focus your attention on a subsystem only, you can define a wavefunction for it as shown. And right at 34:33 you can see how a collapse of this subsystem wavefunction comes about, not via a separate postulate like in standard QM but as a part of the overall dynamics. One of the humps of the subsystem wavefunction gradually vanishes because the horizontal green line does not cut the right blue blob of the overall wavefunction anymore.
It looks like most people here are more interested in the presentation style than the substance. Not that there was any substance. Bohmian mechanics is bullshit. ;-)
@@benli5777 I did. It does exactly the same as Copenhagen, except that it sends you five times around the block and once into the department for supernatural phenomena to fetch a mysterious and unmeasurable guide field. ;-)

Not an especially easy subject to discuss in your own language let alone in another. Well presented and described.
Yes, it was well presented bullshit. ;-)
Great talk!!
Really excellent talk.
Please, people hold your questions to the end. :/

@@BerndSchauderer So? I don't see what point you're making. Are you trying to say that Bohm's theory is right or wrong?
You don't understand bullshit? You are so good at producing it yourself all the time. ;-)
Excellent

The constant interruptions are so annoying. Let the guy talk
The audience is too intelligent to listen well.
I feel like I've wandered into a Kraftwerk songwriting session.
Ironically Schrodinger spoke English with no accent (British accent).

I suggest you carefully study Bohmian Mechanics 🙂

@@schmetterling4477 But not as a big and total bullshit as Copenhagen and that is the difference!
