Reverse Polish Grows on Trees - Computerphile

Why use Reverse Polish Notation? How does it relate to trees in Computer Science? Professor Brailsford explains how RPN arises naturally, as a linearized form of a tree. For further research, the Prof suggests you seek out material on the topics of "Postorder Tree Traversal" and "Dijkstra's Shunting Yard" Correction: In the graphic at 06:30, on the illustration of the second tree, the A is incorrectly labelled as a C.
