Quantum Physics pays a Visit to the Kitchen

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

Yup.  That is the formula for a perfectly-boiled egg.  If you Google 'soft cooked egg' you will get about 5,570,000 results in .55 seconds.  Now there is this:

 

According to Science Alert - quantum physicist Charles D.H. Williams from the University of Exter has determined the precise way to cook and egg to perfection.  Lest you scoff there are many variables to finding the most sublime of soft or hard-cooked egg and Dr. Williams has nailed it.  The bottom line is that the perfect hard boiled egg should be boiled at 170.6 degrees F and a perfectly runny soft boiled egg requires 149 degrees F.  You can read the complete dissertation here.  I have to go now.  Quantum physics makes my head hurt.
