Steven Strogatz returns with his 8th post of the “math, from basic to baffling” series, this time focusing his articulate discourse on the concept of differential geometry.
It is a must read and will leave you a whole lot clearer on things like geodesics and shortest paths.
Loved the final paragraph, which I present below:
Sometimes when people say the shortest distance between two points is a straight line, they mean it figuratively, as a way of ridiculing nuance and affirming common sense. In other words, keep it simple. But battling obstacles can give rise to great beauty — so much so that in art, and in math, it’s often more fruitful to impose constraints on ourselves. Think of haiku, or sonnets, or telling the story of your life in six words. The same is true of all the math that’s been created to find the shortest way from here to there when you can’t take the easy way out.
Two points. Many paths. Mathematical bliss.
