  "**The number decides.** The Reynolds number says which rule applies; the card prints it with every answer it depends on.",
  "**Power goes as the cube.** Twice the speed, eight times the power against drag; the card says so.",
  "**Range warned.** Pipe flow and settling use slow-flow rules; when the flow is too fast for them, the card says the answer is too high.",
  "**Drag area.** The drag coefficient times the front area, the one number a rider or a diver can change.",
  "**Four fluids at 20 °C.** Air, water, olive oil and honey, with published densities and viscosities.",
  "**Unsolved, said.** Whether the full equations always have smooth answers is an open problem; the card works only where answers are plain."
