Perfect boiled eggs

The science and technique of boiling eggs.

So this is what I discovered: given that my burner is consistent in its heat output, given that I use the same pot each time, given that my tap water always comes out at around 40 to 45 degrees, and given that my apartment is at a relatively stable temperature year around, there is a precise volume of water I can use to hard boil an egg such that if I start it cold, bring it up to a bare simmer, then immediately shut off the heat, the water temperature will drop to below 170 degrees just as the central yolk temperature reaches 170 degrees, thereby guaranteeing that my egg will be perfectly cooked every single time.
