Re: Does Cauchy sequence ever occur in the real world or is it all the minds of mathematicians?

How can we teach Cauchy to engineers and computer scientists? They don't teach that in school, Maybe it's because ML and and ANNs don't do Cauchy sequnces. SGD: It's like getting a flat tire and fixing the problem by driving around the block a few times; maybe it will fix itself. The utility of Cauc...

Re: Are you ready for Brexit?

The term "BREXIT" is like certain parts of science; people use the term without knowing what it means, which is not necessarily a bad thing.

Re: American options with two free boundaries

Just saw this thread late. It turns out the double exercise boundary happens naturally for American options under negative interest rates. And you may use the integral formulation to solve the exercise boundary, using similar techniques as in the single boundary case (see Andersen an Lake for examp...

Re: Philosophy As A Way of Life

The world is continuous, but the mind is discrete.
