AI Thread Summary
The discussion revolves around identifying a figure responsible for the death of 25% of the world's population, framed as a riddle. The reference to Cain killing Abel in the book of Genesis is highlighted, suggesting that this act represents a historical interpretation of the question. There is debate over the use of present tense in discussing past events, with some participants finding it problematic. The conversation also acknowledges the complexity of language and interpretation in addressing the riddle. Ultimately, the thread engages with both literary and philosophical implications of the question posed.

Who is the person who kills exactly 25% of the population in the whole world?

Smells like a riddle. In the book of Genesis, when Cain killed Abel, he killed 1 out of 4 people (Cain, Abel, Adam, and Eve). This is your homework?
 
Yes, I like your answer, but it uses the present tense "kills". That would make Cain seem out of the question.
 
No, I disagree. Use of the present tense to indicate something that happened at a past time that you are talking about is a bit arty (frankly it gives me the pip) but not unreasonable. I like Jamesrc's question.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
