I_8_14 = 1/(2*pi)*sqrt(k/m)
I_10_7 = (G*m1*m2)/r^2
I_50_26 = q1*q2/(4*pi*epsilon*r)
thermal_diffusivity = k/(rho*Cp)
reynolds_number = rho*v*L/mu
wave_equation = d2u/dt2 = c^2*d2u/dx2
heat_equation = du/dt = alpha*d2u/dx2
navier_stokes = rho*(dv/dt+v*grad(v)) = -grad(p)+mu*laplacian(v)+f
maxwell_ampere = curl(B) = mu0*J+mu0*epsilon0*dE/dt
