How to (not) organize a university
Mechanics Department: Lagrange's equations
Physics Dept: Schrödinger's equation
Theoretical Physics Dept: Einsteins's equation
Solid Mechanics Dept: Navier's elasticity equations
Fluid/Gas Dynamics Dept: Navier-Stokes/Euler equations
Electromagnetics Dept: Maxwell's equations
Hydraulics Dept: Wave equation
Chemical Reaction Eng. Dept: Convection-diffusion-reaction equation
Physical Chemistry Dept: Kohn-Sham equation
Industrial Economy Dept: Black-Schole's
Energy Dept: Heat equation
Structural Mechanics Dept: Beam and Plate equation
Nuclear Energy Dept: Neutron transport equation
Gas Kinetics Dept: Boltzmann's equation
Traditional model: one department - one equation.
A new paradigm is now emerging
With the development of a general methodology for solving differential equations during the last fifty years (the finite element method), the traditional model is now becoming obsolete and a new model building on interdisciplinary cooperation is emerging (e.g. Chalmers Finite Element Center).
