Question: Scaling Relations and Stellar Evolution Scaling relations provide insight and fast, "back of the envelope' analysis (ok, so yesterday's 'back of the envelope' is today's 'on the real estate of a smartphone screen'). Another description of this approach is 'dimensional analysis. Let's step through an example: derive an approximate relationship that links the mass of a star with its luminosity (the mass-luminosity relation).
