The 2-halfday "Coral restoration" course for divers is very popular here for several years already. The baby corals are planted manually by happy divers and subsequently happily grow. It is inexpensive and fun. These corals will be killed eventually by the climate change just like others.

The idea of not using fire alarms in churches, mosques, and temples, because it was not in the tradition of earlier Muslims, Christians, and Jews, so it is more normal and better without the fire alarms.

Past failures tell you what not to do. Do things which you have never done in the past.

My practical suggestion is to realize that these are empty words. You already have left the past if you wanted or not. It is gone and cannot be changed. You move towards the future if you want or not. It is inevitable. Even a dead rock moves towards the future. Forget about slogans and consider the issues at hand.

Thank you. I have the same wish but can't do more than this as there is no overseas voting in Israeli elections.

Is MAGA a synonym of "Americans"? Who are "the Israelis"? I have an Israeli passport and many Israeli friends and relatives. We are "Israelis," and we have a very good understanding. Thousands of recent demonstrators against the reforms and the government have it, too.

A full video. Several of them. I can stop interfere and just tell you, that this answer is wrong and think of another one. Or I can suggest a mental experiment, like this: It could suggest the answer without more videos perhaps.

I just add information as if you make an experiment and get the result. My only evidence is a detailed explanation of what is happening, but that would ruin the puzzle.

I see. Yes, it is not what I thought it is. Sorry for that. Now I understand your answer. It is correct! +1

Yes. It is not so. It does not make sense. IMO, it was dead on arrival.

Hint:

It is heavy headed.

@exchemist, your answer is correct. +1.

Yes! +1

I assumed you did. I wanted to mention them for other readers.

Why does the hourglass not start rising right away?

Let's make this a bit more interesting. Consider a cylindrical glass and four identical balls packed into it compactly, as shown: How much water is needed to exactly cover the balls compared to the volume occupied by the balls?

However, if x is a complex number, there are many solutions. Not exact, though. One seems to be ~ (-0.28+0.46i), if my algebra is not mistaken.
