Until Last year I have always associated Rails (Ruby on Rails) with quick prototyping of web apps, pragmatic programming etc..

However, My time with stochastics in the last few months has made me give it a new meaning.
In my new world, RAILS stands for Relentless Application of Ito’s Lemma. Stochastic Calculus, once one understands the basic framework , is nothing but RAILS, atleast in the financial world I guess.
