I must be a mathematical bod because I found that easy to follow. Seems to me that it is like music where apparently random notes and rhythms eventually come together in harmony and there is 'rightness' balance, synchronicity about it. Same thing applies to works of art, where the artist, unaware of mathematical principles, produces a masterpiece which is pleasing to the eye and later, a mathematician can explain why the choices, made by the artist for effect, nonetheless conform to established ratios and patterns.
I am hopeful that thanks to these open forums on t'internet, more people whose expertise and knowledge lie in other disciplines than mathematics, interact with the dedicated and highly trained maths bods, bringing new insights to the search for universal 'truths'. I am reminded of my honorary Aunt, a very clever lady who started as a machinist in a wool mill, became a pattern tester and ultimately, working from home when her children were small, devised and wrote the knitting patterns, working only from designer's drawings. She said it was EASY only basic mathematics (she started work at 14) and was always surprised that so few people could do it and no one seemed to understand her explanations. If you knitted Patons and Baldwins patterns back in the 50s and 60s then you have reason to be grateful to this fine woman.
