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.

Freshwater Mussels are important and in trouble
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.

Find optimum radian and diameter of convex mirror
Sorry, but not enough data given to solve this problem.

Find optimum radian and diameter of convex mirror
1. So, you didn't need an angle from the beginning? If you did, could you show that angle on your original sketch? 2. If it is a circular cylinder, then the curvature would be reciprocal of the circle radius. Maybe you're talking about a lens rather than a cylinder?

Interpretations of QM
I am familiar with the models. I just wanted to understand what is I still don't know. Maybe I do... Then my answer to is, No. This is regardless of waves, particles, strings, whatever.

Freshwater Mussels are important and in trouble
The same single study from 2008. The rest is what could happen, I'd like to know if these bad effects in fact occur. Any new data? Preferably by a larger study?

It's emotions. I'd like to see data about the damage they cause. Thank you.

Freshwater Mussels are important and in trouble
Yes, I know. We've discussed it almost a year ago.

Freshwater Mussels are important and in trouble
It perhaps is. Somebody put it together. I don't know of an official body which maintains such a list. Maybe @Lady of Elms does? Or @CharonY?

Interpretations of QM
To better understand this statement, or rather to understand it at all, may I ask if the computer in front of me exists in any meaningful ontological sense?

Freshwater Mussels are important and in trouble
A species I had issues with being on this list is lionfish. It has been discussed in the old thread and I would like to know if there are new data on that:

They define invasive as Perhaps Burmese python would eat farm chicken thus "directly threatening human industry."

Here is a long list: List of invasive species in North America - Wikipedia

The guy doesn't know that this particular thing would overturn anything 😉

Interpretations of QM
Not in his case. He in fact very much values efforts to fight diseases, hunger in Africa (he is from Germany), etc. This was my most effective argument so far. I told him, what if, for example, it will give us a way to get an unlimited energy from nothing?

Interpretations of QM
For example, a neighbor of mine, retired dentist, keeps asking, why do we spend money on origin of the universe and such. I came up with some answers, but he is not satisfied. What would you say? Why do you feel so?

Super sensitive single string hypothesis and extended periodic table
Why should they be multiplied rather than added? When the string doubles in the loop, shouldn't it negativity double as well?
-
The Nature of Time
No, I did not, Yes, I admitted that I don't know the answer. I didn't know it because I didn't think about it in detail. After that, @Markus Hanke and @swansont have answered more specifically.

Find optimum radian and diameter of convex mirror
What do you want to know about the curvature? See Curvature - Wikipedia

Integral Gives Different Answers on Polar Coordinates
The first stop: I think these limits are wrong.
-
Find optimum radian and diameter of convex mirror
I can't say because: 1) according to my calculations, the solution of the equation is about x=87 degrees 2) it is an angle rather than curvature But first you should check the assumptions leading to this equation.

A wave of what? (split from How does the light from distant stars get to our eyes?)
Hmmmmm... Not sure how that happened. 🤔 Maybe I should blame it on @Genady. He explained how to quote text selections, and I probably quoted the quotation in your post. 😶 Hmmmm... I quoted a quotation several times and it worked fine. Just like this one above, nested in each other. But you need to select the quotation completely. Perhaps if you select it partially it gets messed up.

What are you listening to right now?
I am listening to myself playing Aka Tombo on glockenspiel.
