Absolute state of soientists here, what if someting goes wrong and you fall straight into hell? No idea what kind of retard would like to live in such a 'city'.

The real problem is that Venus has basically no hydrogen. So getting water is pretty fucking hard. The clouds of sulfuric acid are a lot sparser than popsci would have you believe.

1 atm on Venus is a bit too hot for humans, going up to where the temperatures are reasonable and it's no longer 1 atm.

Is it possible to have a regular sudoku grid (9x9) where normal sudoku rules apply, but where every possible three by three square inside the main grid has the digits from 1 to 9?

Yes, but Atheist would imply ethnic Russian Atheist not Jewish Atheist. It's just like how Jews call themselves White they want to pretend to be our friends and then call themselves Jews whenever White people are attacked or under threat.

I don't care what you think would imply, atheist jews are the synagogue of satan, the problem of the world is atheism in general no matter what religion they might or might not profess

>It's just like how Jews call themselves White they want to pretend to be our friends
Exactly, they don't have an ounce of Judaism in their life, otherwise they would never call themselves anything other than bnei Israel, those jews you see are all atheists, secular, humanists, etc. as deception, specially against non jews, is strictly forbidden in Judaism

In fact, rabbis have even warned jews decades before Nazi Germany to stop trying to behave like goyim, to stop intermarrying, to stop violating Judaism, yet they didn't listen

I met a librarian in a college near here, and asked her about these sites. She had not heard of them. I was a bit surprised but that was peanuts compared to her astonishment when I explained to her what they do.

It does matter or you will have to justify through magic why the incline makes any difference at all compared to ninety degree free fall where they would both travel at the same speed.
The easy way to identify this by looking at rotational energy in either bottle. The liquid bottle will use less rotational energy if the fluid is weakly coupled to the rotating internal surface of the bottle, but this coupling is dependent on the forces acting on the water which are directly related to gravity(ramp slope) and rotational speed(compounding rotation acceleration, ramp distance). As others have already mentioned, the rotation on the liquid is likely to be less perfect than the rotation of the solid so if the rotational energies are equal then there will be more losses on the liquid bottle, but you really have to be sure that the rotational energies are equal.
Suppose you have two cylindrical oxygen tanks and one is at half of the pressure of the other, which one rolls down a ramp faster?

>>14119030
Free fall, by definition, isn't an incline. An inclined surface is a smooth ramp with angle between 0 and 90 degrees, exclusive. Analytically, the motion of a cylinder rolling down the incline is a function of the coefficient of friction and the angle, true. But such values are fixed regardless of the mass, moment of inertia, etc. of the object rolling. As such, if you want a RATIO of velocities between two different cylinders, the coefficient of friction and angle drop out.

The bottles are filled, meaning turbulence doesn't exist. In other words the water can't swish around. Liquid water is denser than frozen water, as such the liquid water has more mass (and hence higher moment of inertia). So the question boils down to which object hits the bottom first: high moment of inertia or low moment of inertia? This is a trivial intro physics problem.

Quoted By:

I think the essential question is whether the liquid water sees enough friction for it to rotate significantly, and likewise whether the ice adheres to the bottle. If the ice is attached, and the water free, then the bottle with the ice acts with a higher moment of inertia.
