AI Thread Summary
A spinning disk cannot lift itself into the air without a mechanism to generate lift. To achieve lift, it would require additional structures, such as fins, akin to helicopter blades. The discussion also raises the question of whether a spinning disk can move in a chosen direction after achieving lift. The correlation between angular speed and advancing speed is not clearly defined in the conversation. Overall, the consensus is that fins or similar devices are necessary for a spinning disk to effectively lift and navigate.

Can a spinning disk lift itself in the air?

Can it, afterward, advance in a chosen direction?

If yes, what is the correlation between the angular speed of rotation and the advancing speed?
Does it need some "fins" to catch air, similar to the helicopter blades?Thank you very much.

Not without some method of producing lift.

I believe it would.
 
Thank you.
 
Thread 'Question about pressure of a liquid'

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
