Some applications of the Lambert W function to physics

Two standard physics problems are solved in terms of the Lambert W function, to show the applicability of this recently defined function to physics. Other applications of the function are cited, but not described. The problems solved concern Wienʹs displacement ^ law and the fringing fields of a capacitor, the latter problem being representative of some ^ problems solved using conformal transformations. The physical content of the solutions remains unchanged, but they gain a new elegance and convenience.
