text: The so-called Sedov-Taylor solution  has become useful in astrophysics. For example, it can be applied to quantify an estimate for the outcome from supernova-explosions. The Sedov-Taylor expansion is also known as the Blast Wave phase, which is an adiabatic expansion phase in the life cycle of supernova. The temperature of the material in a supernova shell decreases with time, but the internal energy of the material is always 72% of E, the initial energy released. This is helpful for astrophysicists interested in predicting the behavior of supernova remnants.
