The D'Alembert equation for the mechanical waves was written in 1750. It is not invariant under a Galilean transformation.
Why nobody was shocked about this at the time? Why we had to wait more than a hundred years (Maxwell's equations) to discover that Galilean transformations are wrong? Couldn't we see that they wrong already by looking at the D'Alembert equation for the mechanical waves?
Am I missig something?
Thanks,
