The Institute of Reproducing Kernels is dealing with the theory of division by zero
calculus and declares that the division by zero was discovered as 0/0=1/0=z/0=0
in a natural sense on 2014.2.2. The result shows a new basic idea on the universe
and space since Aristotelēs (BC384 - BC322) and Euclid (BC 3 Century - ),
and the division by zero is since Brahmagupta (598 - 668 ?).
