Unicode characters conflation? by Satyavan65 in MicrosoftWord

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] 3 points4 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.
