Einstein: Think of time as a kind of invisible rope that pulls every frame of the building into a new shape. In equations, you’d start with the usual stress‑strain relation σ = Eε, but replace the constant E (Young’s modulus) with a function of time: E(t) = E₀·e^(–αt) to model material fatigue. Then, add a term for temporal deformation, like ε_time = β·ln(1+t), where β captures how the material remembers its past. Combine those in the elasticity tensor and solve the Navier–Cauchy equations in four dimensions—spatial plus time—and you’ll get a structure that flexes with the seasons of the universe, not just the weight of a roof. Just don’t forget the boundary conditions…they’re the real trick!

Einstein: Absolutely, foundations are like the first chapter of a good story; no matter how fancy the equations, you can't skip the ground truth. A solid footing, proper bracing, and a bit of good old engineering keep the building from slipping into a time warp.
