High Quality Content by WIKIPEDIA articles! In Hamiltonian mechanics, a canonical transformation is a change of canonical coordinates (q,p,t) > (Q,P,t) that preserves the form of Hamilton's equations (that is, the new Hamilton equations that result from the new Hamiltonian constructed by transformation may be simply obtained by substituting the old variables by the new ones), although it might not preserve the Hamiltonian itself. This is sometimes known as form invariance. Canonical transformations are useful in their own right, and also form the basis for the Hamilton–Jacobi equations (a useful method for calculating conserved quantities) and Liouville's theorem (itself the basis for classical statistical mechanics).
