Query: Magnetic Monopoles in (Noncommutative) Quantum Mechanics   We utilize the close relation between the complex space $\textbf{C}^2$ and
the real space $\textbf{R}^3$ to reformulate quantum mechanics in a manner
which allows to, either or both, describe magnetic monopoles and quantize the
underlying space, obtaining (noncommutative) quantum mechanics (with magnetic
monopoles).
