I think this is called spontaneous symmetry breaking.

The Fench/German/Japanese rover Idefix will explore the surface of Phobos before the MMX spacecraft lands.

Yes, but the initial condition of the system is not symmetric, because one side is up before the coin is thrown. There exists a "same-side-bias" of 50.8%. Source: https://www.mpi.nl/publications/item3674839/fair-coins-tend-land-same-side-they-started-evidence-350757-flips Where could the...

Please consider a 1 photon double-slit experiment, which is symmetric regarding left/right. If a photon is detected on the left side of the photographic plate, how can a deterministic process in a symmetric setup create an asymmetric result?

In the co-rotating frame, the centrifugal force does work, because the marble moves away from the Earth axis. It is compensated by negative work of Earth gravity.

No. Both, plus calculating to solve problems, are needed for successful lerning.

I don't know, but I found something related: https://mathworld.wolfram.com/EuclideanQuantumFieldTheory.html

Yes. To be more precise: For the free-falling observer, a nearby body on the ground has locally a coordinate-acceleration relative to the falling (=inertial) frame of approximately ##9.81 \ m/s^2## (for ##v<<c##). An observer in a locally free falling elevator-cabin can throw a ball an notices...

Yes. It is the unphysical first case ##K=-1## in posting #2, which is an Euclidean rotation in the ##xt## plane. ##\begin{pmatrix} x'\\ t' \end{pmatrix} = \frac{1}{\sqrt{1-Kv^2}} \begin{pmatrix} 1 & -v\\ -Kv & 1 \end{pmatrix}## ##\begin{pmatrix} x'\\ t' \end{pmatrix} = \frac{1}{\sqrt{1+v^2}}...

That's true, but I didn't claim that it is the same. With "4D-Euclidean metric" I referred only to the OP.

Given the assumptions in the paper "Nothing but Relativity", including group properties of a transformation (two boosts in one direction are equivalent to one boost of the same form), https://arxiv.org/abs/physics/0302045 the Lorentz transformation as physically relevant follows only for one of...
