Sneddon’s derivation using the method of characteristics is legendary for its clarity.
Originally published in the 1950s (and reprinted many times since), it remains a go-to resource for advanced undergraduates and beginning graduate students in mathematics, physics, and engineering.
Ian N. Sneddon was a renowned mathematician who made significant contributions to the field of mathematics, particularly in the areas of partial differential equations, integral transforms, and mathematical physics. He was a professor of mathematics at the University of Glasgow and wrote several influential books on mathematics.
