Ben non, des m=C3=AAmes =C3=A9quations ne peuvent d=C3=A9crire deux choses =
distinctes, une trajectoire et une transformation. Boire ou conduire, il fa=

C=E2=80=99est bien ce que je disais, les physiciens ne savent pas ce qu=E2=
=80=99est une transformation ponctuelle (https://fr.m.wikipedia.org/wiki/Af=
finit=C3=A9_(math=C3=A9matiques)). J=E2=80=99essaierai de trouver quelque c=
hose de plus simple ult=C3=A9rieurement.
