there is math in finance just as there is math in accounting but perhaps a bit more because risk and geometric growth are important components of finance; but that does not really mean it's quantitativeness implies some relationship with physics or Galileo or the physical sciences. finance and economics are social sciences and the study of human behavior is an important aspect of these fields which surely you know if you have been following the work of Kahneman and Tversky. I think people like Markowitz, Miller, Sharpe, Black, and Fama have made significant contributions to our knowledge of how the financial sector of the economy works. There have been some dead ends in financial research as there has been in any field, bubble theory being one of them. I don't think we will ever get to the end of the 2008 debate but we will learn a lot in the debate and your contribution is therefore of course a positive contribution. thank you.
