A pre-Jesus-like figure, likely possibly a mentor or competitor with Jesus.
He would have deserved a scene in Jesus Christ Superstar (1973).

Game of chance Updated +Created
The definition is not very precise, as in many games with random elements there is a mixture of both skill and luck.
So we just use the precise Non-deterministic game term instead for any game that has any random element beyond the control of the players.

Position and momentum space Updated +Created
One of the main reasons why physicists are obsessed by this topic is that position and momentum are mapped to the phase space coordinates of Hamiltonian mechanics, which appear in the matrix mechanics formulation of quantum mechanics, which offers insight into the theory, particularly when generalizing to relativistic quantum mechanics.
One way to think is: what is the definition of space space? It is a way to write the wave function such that:
  • the position operator is the multiplication by
  • the momentum operator is the derivative by
And then, what is the definition of momentum space? It is of course a way to write the wave function such that:
  • the momentum operator is the multiplication by
physics.stackexchange.com/questions/39442/intuitive-explanation-of-why-momentum-is-the-fourier-transform-variable-of-posit/39508#39508 gives the best idea intuitive idea: the Fourier transform writes a function as a (continuous) sum of plane waves, and each plane wave has a fixed momentum.
