lorentz transformation and lorentz-einstein transformations

bernhard.rothenstein

I find in the literature of the subject:
Lorentz transformations and Lorentz-Einstein transformations. The use of one or of the other could lead to a difference in interpretation?
Thanks

I think most people loosely use them interchangeably.
In strict terms, saying simply LT is a misnomer (even though we all use it).
Lorentz meant a real physical change in the matter in order to avoid SR.
The L-ET is a change in the coordinate system in order to leave the matter unchanged, which is SR. I confess to still saying LT when I mean L-ET.
It's sort of like saying "I weigh 80 kilograms."
