Where zero doesn’t mean nothing

By Njoroge Kinuthia

This is a subject that could have greatly interested the late Prof George Saitoti. But we hope that it will be of great interest to his students (not political students!). If you aren’t aware,  Saitoti’s doctoral dissertation focussed on the mathematical functions of zero. And although PointBlank doesn’t know what these functions are, it has got wind that a zero doesn’t necessarily mean naught. Just ask Airtel customer Ms Beatrice Kogei (mobile [phone]). Or, well, let’s just explain briefly.
