 I find you very harsh.

No, that was not my intention.
But I had the idea, that mathematicians mainly think in terms of mathematics. But math and physics are not the same thing.
Poincaré was actually an extremly good mathematician.
And I was personally unable to understand most of his work.
But Poincaré wasn't my topic, anyhow, hence I noticed Poincare and tried to read a bit of 'Sur le dynamic d'electron' in  French.
Unfortunately I cannot speak French good enough, only a little bit.
His math is also way too difficult for me.
I have read a few papers about Poincare, hence I know a litle bit about his work from second sources. But that's more or less it.

The Poincaré equations in relativistic physics are magnificent.
They are true, they are beautiful, they are coherent.
Einstein, next door, is Laurel and Hardy.
