You can practice economics as a science. For example, the book "Critical Mass" by Philip Ball ( http://www.philipball.co.uk/index.php?option=com_content&view=article&id=15:critical-mass-how-one-thing-leads-to-another&catid=3:books&Itemid=4 http://www.philipball.co.uk/index.php?option=com_content&vie... ) includes a fair amount of economics from a thermodynamics perspective. However most of economics is not approached in this fashion and is more comparable to Axel Leijonhufvud's satire "Life Among The Econ" ( http://www.econ.ucla.edu/alleras/papers/life%20among%20the%20econs.%20leijonhufvud%201973.pdf http://www.econ.ucla.edu/alleras/papers/life%20among%20the%2... ).
