Once you know all your variables, you need to plug it into Williams' formula.
t = m * K * log(ywr * (Tegg - Twater)/(T - Twater))
t = time
m = mass
K = thermal conductivity of the egg
T = temperature between white and yolk
Tegg = egg temperature
Twater = water temperature
ywr = yolk-white ratio
Life used to be far less complicated. The chicken laid the egg, nobody cared if it was range free or organic and probably NO ONE ever thought boiling an egg required quantum physics!
ugh!
