    so I'm kind of unsatisfied with my knowledge about left and right-handed coordinate systems. I keep finding these hand-rules as an explanation whereas I'd have to like something which actually gives me a motivation for the definition and also gives me a more mathematical definition. And maybe some intuition. E.g.

  • Rotation matrix between right- and left-handed systems, with an ...
    A is a right-handed system, and B is a left-handed system. Furthermore, after moving from a right- to a left-handed system, there is a further rotation. These two coordinate frames are illustrated in the image below. As can be seen, it appears that the axes in B are simply the negative of the axes in A.

  • Iterative methods for solving a linear system with many right-hand ...
    Block Krylov methods are designed for your situation, i.e., multiple right-hand sides. In general, you can use the Krylov subspace generated during the solution of one system to accele-rate the solution of another system with the same coefficient matrix. This procedure is known as Krylov subspace recycling.

  • Can a purely mathematical version of the right hand rule be given?
    The right hand rule is a common convention for describing orientation of coordinates, used throughout physics. It's also used in the definition of the cross product. Is it possible to give a purely mathematical definition of the right hand rule, which doesn't reference anyone's hand? What is unique about the right hand that the RHR captures?
