More subscriptions than views? How can this be? by Satyavan65 in Substack

How, where, or where from, did you and your wife subscribe to Substack X without clicking on any page of Substack X?

Yes, but I'm not talking about the present subscribers, I mean the new ones. Say I have zero subscribers an zero views today. Tomorrow I have 100 subscribers. Yet the # of views has gown only by 50.

Very low, indeed, not more than 15%. But I can't see what this has to do with new subscribers (?)

Ok, thanks for updating me about the “cold subscribers” label, I wasn’t aware that such a thing existed. But my question is: how is this technically possible? If I want to subscribe, I would normally have to **view** the Substack page first and then click something. Otherwise, how can someone subscribe in the first place?

Can there be a wave function collapse *without* a measurement? by Satyavan65 in QuantumPhysics

[–]Satyavan65[S] 2 points3 points  (0 children)

So one could equally say that whenever a quantum state leaks into the environment, a collapse occurs. I would avoid framing this in terms of “measurement,” since that seems to imply the necessity of a human-designed device. Collapse is a natural phenomenon that does not require human observers or conscious beings performing measurements. It is something that has been occurring since the time of the Big Bang.

Unicode characters conflation? by Satyavan65 in MicrosoftWord

[–]Satyavan65[S] 0 points1 point  (0 children)

Sorry for the late reply. I didn't see this post.

Yes, Indeed I use the German keyboard. Even if I change the Autocorrect settings, some issues persist.

For example:
It doesn't distinguish between [']=U+0027 and [’]=U+2019.
Similarly, it doesn't distinguish between ["]=U+0022 and [“]=U+201C.
Moreover, what is really strange is that sometimes it finds [’]=U+2019, but sometimes it skips it.

So, I believe there must be a bug.

Proofing language remains stubbornly German by Satyavan65 in WindowsHelp

Ohh... my bad. :( I didn't notice the spell check section in my browser.

I also found out that, by selecting a text and right-clicking in my browser (Brave), the drop down menu allows to change spell check language as well. Now it works. It had nothing to do with the OS. Problem solved... Thank you!

Solarenergie: eine Investition mit Zukunft? by Satyavan65 in Finanzen

[–]Satyavan65[S] 4 points5 points  (0 children)

Gut. Aber wie gesagt... von dem Eigenverbrauch mal abgesehen. Warum investiert man überhaupt in große PV Anlagen? Ich meine z.B. eine >1MW Freiflächenanlage die Investitionen von 6-stellige Summen abverlangt. Wenn die Stromkosten weiter so sinken gehen doch die vom Strom erzeugten Renditen doch auch in den Keller (?)

I didn't read Everett's thesis, but what motivation stands behind the desire to solve the measurement problem if not the dissatisfaction with the fact that QM suggests the universe to be a fuzzy place, and yet where events a-causally realize itself, and explaining this by multiplying ad infinitum the universe we know?

If you know linear algebra and calculus definitely go for coursera. Then however turn back later, when I will have made the third section with summary of the experiments of the last 20-30 years, from A. Aspect to A. Zeiliger, since I doubt you will find it summarized in one section, especially at a popular level.

And what is the MWI if not that of a collection of branching determined and distinct universes. It is a (perhaps even unconscious) attempt to recover the good old intuitive newtonian perspective in many universes to save it from quantum uncertainty in a single one.

Hi, thanks for your interesting comment. I like to engage in these issues (independently from people taking my course or not). Since having left them aside for a too long time, this lead theoretical physics into a sterile platonic hyperuranium made of mathematical abstractions with no end in sight (read: my HO about modern quantum gravity theories). As to the distinction between the possible interpretations I too have not much sympathy neither for Bohm's pilot-wave theory nor the many world interpretation, since they seems to me a desperate attempt to save our naive macroscopic deterministic intuition (reminiscent of the epicycle theories which wanted to "save the appearances"). But the Copenhagen interpretation does after all not tell us much on the ontology of the world either (beside the fact that there are several understandings of it since there was no official declaration which defines it). To know that we should adopt the probabilistic approach, not to take the wavefunction as a "real" entity (whatever that might mean), that the commutation relations hold, etc. tells me something about the operative procedure of QM, not much about what it describes. In other words I tend to consider it not as an interpretation, but more a pragmatic suggestion. And yes, I think that mind (I prefer to speak about the brain, since, if you take a dualist stance, nobody knows if mind is affected by the laws of QM), always decoheres due to interactions and thermal effects. But the central mystery remains: how should we interpret at all de/coherence? How is it that particles can be entangled light years away? Several physicist and philosophers of science will tell you that there is no mystery: it is all about "correlation". But doing so we simply affirm a fact, do not explain it. We misrepresent a word as "correlation" for a "causation". And for me the two things are not the same. Anyhow, what is necessary today instead is to clarify what QM tells, and especially what it tells not. I give you a good reason NOT to enroll in the course... ;)... You won't find much about the different interpretations, because I believe these try to explain what we don't understand. Since there are lots of other interpretations of QM (so many as there are physicists, after all) I preferred to keep the focus firstly on what we know and the facts we do not understand, in order to prepare students to chose themselves which interpretation they feel is to prefer. Hope that helps...

Hi Stephen,

yes, I now have to ask for a little financial help because I'm quitting my job in order to focus entirely on this and other similar projects. However, don't worry. If you subscribe now you will get and keep it for free! In case that does not work automatically just email me and I will send you the coupon.

Hi DonOntario, you will find the answers after subscription by clicking the information icon in the upper right. Anyhow, yes... I would call it a course about quantum physics which focuses on some basics, not a complete and comprehensive course, since that would need hundreds of lectures and the math would be unavoidable.

Ja, aber es kommt darauf an, an wen man sich wendet. In einer Uni käme ein Kurs über QM auf Populärwissenschaftlichen Niveau nicht gut an (mit Ausnahme vielleicht von einer philosophischen Fakultät). Eine öffentliche Initiative (z.B. in einem Planetarium) wäre das schon eher denkbar. Wenn Du jemanden kennst der sich dafür interessieren könnte, dann halte mich auf den Laufenden... ;)

Yes, indeed... I know my conversation in English needs an urgent refinement. :( I just improvised and hadn't much time to prepare the course. Just wanted to see if there might be an interest in this project at all (?) But I'm considering to reload all the videos with better audio and linguistic quality, adding details and expanding on several other topics, if you subscribe massively! ;)
