"Kairos is an ancient Greek word meaning the right or opportune moment (the supreme moment).
The ancient Greeks had two words for time, chronos and kairos. While the former refers to chronological or sequential time, the latter signifies a time lapse, a moment of indeterminate time in which everything happens." Wiki.

So MPJ has got out of nickel at the right or opportune time. And also got into lithium at the right or opportune time.. the supreme moment.

Hence the new name.

Good? Bad? the ancient Greeks were pretty smart, but it is still all Greek to me!.
