I Magnetic dipole in vacuum near absolute zero

AI Thread Summary
A single atom in a vacuum at near absolute zero is expected to retain its magnetic dipole due to its intrinsic properties. The magnetic moment is determined by the atom's ground state and its total spin. Atoms with half-integer total spin will definitely exhibit a magnetic moment, even in the absence of external fields or interactions. There is curiosity about whether this phenomenon has been experimentally verified. Overall, the existence of a magnetic dipole in such conditions is supported by theoretical understanding.

TL;DR Summary
Will the magnetic dipole of a single atom in vacuum at near zero kelvin still exist?
Consider a single atom (or particle) in a vacuum (without electric, magnetic or gravitational field) at near zero kelvin (i.e., no photons or particles striking it). I am curious if it will still have a magnetic dipole? If there still is (which I believe), had this been shown experimentally?

Why would you think that the atom's magnetic moment will not exist near zero Kelvin? The atom will have the magnetic moment of its ground state. If it has a half-integer total spin, it will most certainly have a magnetic moment.

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...

Thread 'Time of flight measurement uncertainty'

Hello! I am generating electrons from a 3D gaussian source. The electrons all have the same energy, but the direction is isotropic. The electron source is in between 2 plates that act as a capacitor, and one of them acts as a time of flight (tof) detector. I know the voltage on the plates very well, and I want to extract the center of the gaussian distribution (in one direction only), by measuring the tof of many electrons. So the uncertainty on the position is given by the tof uncertainty...
