AI Thread Summary
A 1000 kg car moving at 10 m/s with an uncertainty of 0.001 angstrom/s raises questions about its position uncertainty according to the uncertainty principle. The discussion highlights that the uncertainty in position is negligible compared to the car's physical size, which is affected by stresses and elastic deformation. It emphasizes that both macrocosmic and microcosmic objects cannot exist in two places simultaneously. The comparison of quantum mechanical uncertainty with physical deformation illustrates the limits of applying quantum principles to everyday objects. Overall, the conversation underscores the distinct differences between quantum mechanics and classical physics in practical scenarios.

A Macrocosm thing, example a car, can be exist two different places in the same time ?

Why don't you work out an example. Suppose that you know that a 1000 kg car is moving at 10 m/s with a ridiculously low uncertainty of 0.001 angstrom/s. According to the uncertainty principle, what is the uncertainty in the position?

How do you think that quantum mechanical uncertainty in position compares with the uncertainty in the size of the car due to stresses and elastic deformation?

No. And neither can a "microcosm" thing.
 
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...
