A physicist, an engineer, and a mathematician are in a hypothetical theater when the stage curtains catch fire. The physicist makes some measurements as to the volume of curtain, available air flow, chemical properties of the curtain, flow rate and thermal capacity of the water hose and water, formulating a precise equation for how much water is necessary to put the fire out when starting at a given time, and precisely puts the fire out. The engineer makes a few quick estimates as the the volume of fuel and air, uses that to estimate the amount of water needed, doubles it, and puts the fire out (with safety factor 2). The mathematician looks at the fire, looks at the fire hose, states: "The problem is solvable", and exits stage left.
