First, assume a spherical cow on a frictionless plane in a vacuum. The classic simplifying assumption, finally drawn properly: a perfectly round cow with spots, a face and four stubby legs, radius dimensioned at 0.52 m (yes, we checked: 600 kg at 1000 kg/m³), drag none, moo negligible, and a red-pencil "close enough."

What you get

  • Front: Left-chest spherical cow, "Assume a Spherical Cow · μ = 0 · In a Vacuum"
  • Back: "ASSUME A SPHERICAL COW" over a spherical cow inside a dotted VACUUM boundary on a frictionless plane (μ = 0), with r = 0.52 m dimension, givens m = 600 kg, ρ = 1000 kg/m³, V = 0.6 m³, Drag = none, Moo = negligible, and "Fig. 18"
