The Gaza Riviera ?
Good, and good to know. Thank you. Last year it was in the news a lot, this year - none. Btw, an OT question. How did you know that those Jews were Ashkenazy? P.S. Ah, the shtreimels. Were they from Neturei Karta - Wikipedia?

Where are the pro-Palestinian protesters that were so loud a year ago?

I didn't try a polar though...

I don't drink bear because of an allergy.

I thought that the word "truth" is just a shortcut for "true proposition", like in "The truth is that he was not there."

Is it possible to calm down individuals or large groups in post-conflict or conflict prone settings ?
One of such means is to get or to make a common enemy.

Are tangent points allowed in ruler and compass constructions?
No, I should not. Nevertheless, I've posted my solution of the Problem A in the beginning of the thread, here:

How to solve the equation?
Time to learn some LaTeX. E.g., \(d\sin(a)=\cos(a)~ da\)

When I've mentioned this metaphor to my neighbor, an experienced dentist, he replied that there is nothing wrong with the “north of the North Pole”: you just keep moving up.

But it is not. ...... What part of the following statement don't you understand? ..... Yes, but your second arc is wrong. ..... Did you read this statement: I don't need help in solving these problems!

This problem is not asking to find a midpoint of A and B. It asks to find a point C such that B is the midpoint of A and C. Anyway, here is a drawing according to your steps. It does not seem to work.

Gap between life and non-life (split from What if god...)
It does not matter.

They all support the chemical-physical view of life.

Maybe. Maybe not. Go ahead, investigate. When you have something, maybe there will be something to discuss.

It does not. Computer works with pseudo-random. Which is non-random.

Binary is the basis. Random/non-random. 0/1.

Problem A. Draw two arbitrary points on a sheet of paper. Call them point A and point B. Find the location of point C such that AB = BC. Use only compass. Here is the drawing:

No. I have explained what I wanted in the post which is two posts above this one. Here is what I have explained there:

I don't know how you got the problem you describe. I've never mentioned anything like that. I have mentioned two other problems earlier in the thread. Problem A: Problem B: Emphasis is on "compass only". No straightedge, no straight lines, nil, nada, niet! The question in the thread was NOT how to solve these problems. I've solved both of them. (Without drawing any straight lines.) My initial solution used a point where two circles constructed on an intermediate step, touch each other. I was not sure, if it is legitimate to rely on a point that was constructed this way. However, I've found a way how to construct such a point by constructing another circle which crosses the two tangent circles at the point where they touch each other. This shows that using a point where two circles touch is a legitimate shortcut of this a bit longer but definitely legitimate construction. So, the question in the title of the thread is answered. If you want to play with them, try the Problems A and B yourself. But remember, no straight lines are allowed.

1. I don't know which problem you are solving. 2. It should be easy to describe a construction in words if the circles and points are named. Let's try. a. Let's call the given circle, C1. b. You say to "Use an arbitrary radius that is slightly bigger than the radius of the given circle." I set the compass to some radius like that. c. "make 4 arcs with the compass from each quadrant." With the radius set in (b), I make circles C2, C3, C4, and C5 with the centers in A2, A3, A4, and A5, respectively. They intersect in several points with C1 and among themselves. d. "This will give you the center." Where is the center? The center of what?
