mathematical structure such that:

 wow, thanks, this elaborated cretin is only a baccalaureate? ?  What the hell is he doing in science groups, annoying people.

Exactly.
He annoys everyone for the sake of annoying them.

What a piece of garbage. Thank you for this vital information

 It's not an information.
 Everybody knows that.
 It took me three months to explain to him what apparent velocity was in astrophysics.
It's actually very simple; it's a kind of Doppler effect. When a body approaches you very quickly, you have the impression of a greater speed, and vice versa if the body moves away. Apparent velocity is the speed measured from our perspective on Earth, which can be influenced by geometry, relativity, and other optical or physical effects.
Here, Vapp = v/(1 + cosµ.v/c)
It took him three months to understand.
That's when I realized he hadn't gone to school as a child.
But let's not say any more. I don't want to be mean.
