The Half-Life of Singapore Math

The time it takes for the bar model method, the heart and soul of Singapore math, to become a common feature in most math curriculums around the world, which implicitly means that it no longer holds the competitive edge over other developed nations in math education.

the half-life decay of plutonium-239 in a zinc-aluminum material lined caging

caged plutonium which is a transuranic material that has a half-life of 24,065 years, making it decay (into different elements) inside a zinc-aluminum hull (the aluminum delicates due to the radiation and thus might crumble depending on the weight of plutonium-239) but doesn't rust as easily due to the zinc coating
