I understand that Schrodinger's equation is an axiom of QM but that's not an excuse to not give at least a motivation for where it comes from, surely Schrodinger didn't just wake up one night with this equation in his head, right?

Yes, i found that studying QM the historical way (i.e. how QM concepts came about and developed historically) is the only way which makes sense to me.

The bladder contracts and the urine gets out, just as in the same way the water gets out when you push the piston of the pipette.

The bladder muscle (Detrusor muscle) is a smooth muscle, smooth muscles work differently from skeletal muscles, the bladder contracts and it stays contracted, actually, the new contracted state becomes the relaxed state, this ability to redefine the relaxed state is one of the unique properties of smooth muscle and is technically known as "plasticity" (microscopically this is due to rearrangement of myosin and actin cross-bridges), so the bladder stays like that until it becomes distended with urine again and the cycle repeats.
>Is it possible to train this muscle?
No because it is a smooth muscle, and smooth muscles are involuntary.
