In thermodynamics, the term Triple Point refers to a confluence of physical parameters such as temperature and pressure, under which a substance can exist in all three phases, i.e. gas, liquid, solid, so that very small changes in this equilibrium can transform it from one phase to another. Water, the most remarkable substance, has a triple point that we all are familiar with – it is the set of conditions found on the planet Earth. It can be said that life on Earth is a lucky consequence of the triple point of water.
And it can also be said that in one’s life, the term triple point may be ascribed to a confluence of circumstances, a crossroads of paths, a node of potentials and possibilities, in which very small nudges can make the whole thing evaporate, liquefy, or become solid.
