A piano is as much a mathematical instrument as it is a musical instrument. The history and the various logics that have been applied to its tuning is a fascinating one. This blog introduces the some of the reasoning that has led us from the days of perfect harmony to a modern day tempered pragmatism. ![]()
Getting a refreshing geometrical bent to the algebraic problem of finding quadratic roots provides fertile ground for upper secondary students. This blog investigates geometric methods that were developed by the 17th century French philosopher, mathematician and Scientist Rene Descartes and the 19th century philosopher, essayist and mathematician Thomas Carlyle. This is great material for classroom investigations or project work. ![]()
Echoing the intent of some articles recently published in the Australian Mathematics Education Journal, we encourage the use of puzzles in the classroom as an effective pedagogical strategy. This blog traces our own experience of discovery and of being led to make connections between the problem at hand and some half-forgotten pieces of mathematical learning. We argue that students are likely to feel motivated just as we were, given the stimuli of suitable puzzles. ![]()
George Gamow’s book One Two Three…Infinity – Facts and speculations of Science published in 1947 by Viking Press and reprinted by Mentor Books for the New American Library in 1953, included a problem about a lost treasure. According to Gamow’s original story, there was a young and adventurous man who found, among his grandfather’s papers, a parchment that revealed clues to the location of a great treasure. According to the parchment, the treasure was buried on a certain island, and using two prominent trees and an old broken Gallows the exact location could be obtained. Alas the Gallows were gone, and despite the young man digging holes all over the island, the treasure remained hidden. While the authors in this blog have added their own colour to the story the original puzzle remains completely intact. Three separate proofs are given that show that the location of the Gallows was irrelevant to finding the treasure, but please don’t tell that young man. ![]()
