This is an Einstein law.
And the towarišč solcnekot is a good proof.
Even though this schematic is from the number of stages the most complex I've tried
in my "towarišč" experimenters toolkit, it's the best sounding - at least to my taste.
As always it's up to you, to believe that. But you don't need to believe that,
just proove it by building it and trying the other alternatives.
Have a nice weekend !
