How Is A Mathematical Proof Like Frodo’s Journey InLord Of The Rings?

When people describe a story as being told in a “ by the numbers ” style , that ’s normally affect as bad . But in a talk at Oxford University the other day , scientist Marcus du Sautoy argued that a slap-up numerical proof is a lot like a chronicle . In fact , a really enceinte trial impression is like Frodo ’s journey in Lord of the Rings , from the familiar to the novel .

Du Sautoy explains :

“ A cogent evidence is like the mathematician ’s travelog . Fermat gazed out of the mathematical window and spotted this mathematical superlative in the space : the statement that his equation do not have whole - number solution . The challenge for subsequent generations of mathematician was to find a tract leading from the intimate territorial dominion that the mathematician has already navigated to this extraneous new land .

[ It ’s ] a bit like Frodo ’s adventures in Lord of the Rings . A proof is a verbal description of the journeying from the Shire to Mordor . Within the boundaries of the intimate landed estate of the Shire are the axioms of math , the self - evident verity about numbers — together with those suggestion that have already been rise . This is the setting for the beginning of the pursuance . The journeying from this home territory is then bound by the rules of mathematical subtraction , like the legitimate moves of a cheat opus , prescribing the steps you ’re countenance to take through this world .

At time , you ’ll make it at what looks like an impasse , and need to take that characteristic sidelong footstep , move sideways or even backwards , to find a way around . Sometimes , you need to wait around for new mathematical characters — like imaginary bit , or the calculus — to be create , so you could take that next whole step . The proof is the story of the trek , and the map chart the coordinates of that journey . The mathematician ’s logarithm . ”

you’re able to determine the whole event , which was livestreamed and recorded for descendants , over at Oxford University . Besides du Sautoy ’s 20 - minute talk , there are answer by author Ben Okri , mathematician Roger Penrose , and literary assimilator Laura Marcus , and an audience inquiry - and - reply school term .
