I'm trying to wrap my head around the concept. we use 3 rotations to transfer our regular cartesian coordinates (3 x,y,z unit vectors) to other 3 unit vectors. each rotation is associated with an angle. so far I'm good.
but now I saw in Landau's and Lifshitz's "mechanics" book this thing (picture attached).
I couldn't understand where omega is and what we are trying to do.
Is omega the rotation of the new system in the old system, or just some rotation vector who is constant in the new system that we are trying to express in the old system ? (so far that makes more sense since we got a result who is dependent only on Euler angles and their time derivatives)
