This month's column deals with a problem often referred to as the "problem of Regiomontanus" and it is reputed to be the first maxmin problem of the modern age. 'At what point on the ground does a perpendicularly suspended rod appear largest (i.e., subtends the greatest visual angle)? It has been claimed that this was the first extreme problem in the history of mathematics since antiquity'. (orig.)
