Is 'Democracy' like 'Equality' ?
I understand that democracy is a rule of majority. It is inequality then.

What would be the most important thing than humans should try to achieve in priority in your opinion ?
I believe that such a thing does not exist. There are many different "bests", for different groups of people.

Which proven law does definition of imaginary number "i" follow?

Interpretations of QM
I think that the difference between physics and mathematics is that - paraphrasing Feynman - in physics we got a partner.

Is it a proven law? I think, this equation is incorrect. For example, x*log(x)→0 when x→0 and log(x)→-∞.

I'm with you here 100%. However, Isn't thinking about ontology another substitute for physics?

How does the light from distant stars get to our eyes?
Exactly. Thus, no contradiction.
-
How does the light from distant stars get to our eyes?
There is a big range between "only one direction" and "all directions". No photon emitted from the opposite side of a star reaches us. (Ignore BH and alike.)

He is right.

Schrodingers cat question
The "state of cat" is entangled with the "state of bomb" as well as with states of everything else the cat interacts with. To separate the "state of cat" from all this mess, one needs to sum up (integrate) this entangled state over all variables describing all other parts of the entangled system. The resulting "state of cat" is not a pure quantum state, but rather a mixed state with classical probabilities, something like "50% chance it is dead and 50% that it is alive." This is not unlike "50% heads and 50% tails" of a coin before we check it. Nothing paradoxical here.

Freshwater Mussels are important and in trouble
It might be useful to investigate, why it doesn't have these effects in the waters of Bonaire.

The Double Slit Experiment Reexplained.
The wave is not canceled. Its shape changes. Fewer particles appear in some areas while more particles appear in others. With the same total. There is a destructive and also a constructive interference.

Is a definition of Dirac delta function free? Which proven law does it follow?

Interpretations of QM
A historical analogy doesn't prove anything of course but can work heuristically. By analogy, no efforts to disprove classical mechanics or find where different interpretations of it could produce different results have brough a breakthrough. The breakthrough rather came from different developments, i.e., EM, thermal radiation, spectroscopy. By this analogy, I'd expect the next breakthrough to come from a different development as well. Cosmology? Something else?

Interpretations of QM
Aren't we in this situation for a few decades already? About 3 or more?

Definitions are not Free!
Which specific intuition does it contain? Then what does?
-
Definitions are not Free!
A procedure of following from intuition has to include intuition on one or more steps. Just like a procedure of following from axioms has to include the axioms on one or more steps.
-
Definitions are not Free!
Yes, it does. Otherwise, it does not "follow from intuition."
-
Definitions are not Free!
There is no "intuition" in this text.

Definitions are not Free!
How do you know that it follows from intuition? Whose intuition? How does a procedure of "following from intuition" work?

Freshwater Mussels are important and in trouble
Taking about invasives, or not. This plant has appeared in my yard about two years ago and grew taller than 2m by now. Evidently, very happy. Constantly blooming and making fruits. It is Noni, Noni | NCCIH (nih.gov), I am in Southern Caribbean, on an island with no lava flows since it appeared out of the ocean. How the Noni seed got to my yard? Perhaps via humans somehow, unknown to me. Is it invasive? I don't know. I hesitate to take a preventive measure...

Question about evolution
When the asteroid hit, today's Mexico and East Africa were not where they are now. They were much closer to each other, separated by only about 80 degrees of longitude. Anyway, the extinction event was global, affecting the entire planet, but differentially affecting different life lineages.

Yes. The official site mentioned above, has the following disclaimer on every page: (my emphasis)

Find optimum radian and diameter of convex mirror
A sketch of what it is you're talking about, for the starter. The original sketch does not correspond to what you say now.

Interpretations of QM
Maybe the issue is not QM but rather probability? Entropy is another statistical concept that causes lots of confusion.
