What are relation between unique describe of world and covariant law?

AI Thread Summary
The discussion centers on the idea that individuals perceive and describe the external world uniquely based on their circumstances, whether stationary or in motion. This leads to the conclusion that the laws of physics remain consistent across different coordinate systems, a principle evident in General Relativity and, to a limited extent, in Classical Mechanics for inertial frames. The conversation raises questions about the relationship between unique descriptions of the world and covariant laws. It highlights how both theories of relativity challenge traditional notions of simultaneity and absolute motion. Ultimately, the perspective from which one views the world significantly influences their understanding of physical laws.

If we consider have an unique external world therefor all people who want to describe this, should portray one thing.

it seems logically that all people with different situation, either they are stationary or they move with constant speed or variable speed, describe world uniquely.

this condition leads to the laws of physics to be the same in all different coordinate system - in General relativity, we see this but in Classical mechanics, its true only for inertial coordinate system -

here arises a question, what are relation between unique describe of world and covariant law

Hi sadegh4137,

I think you've answered your own question: it depends on your point of view (your frame of reference).

Both theories of relativity up-end the ideas of simultaneity and absolute motion.
 
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...
