First of all, it's not true that all important differential equations in physics are second-order. The Dirac equation is first-order. This is correct. However, physical evolution equations are second (in time) order hyperbolic equations. In fact, each component of Dirac spinor follows a second order equation, namely, Klein-Gordon equation.

Apr 30, 2012 · April 30, 2012. by Mini Physics. A second order differential equation is of the form ad2y dx2 +b dy dx + bdy dx + cy = f (x) a d 2 y d x 2 + b d y d x + b d y d x + c y = f ( x). f (x) f ( x) is called a source term or forcing function. The differential equation is called. a homogeneous equation IF f (x) = 0 f ( x) = 0.
