20:32 UTC Revision 1 . . . . Marcin BorkowskiI’ve been a fan of accounting for a long time now. My affair with bookkeeping started when I studied economics, and took a course in Financial accounting (not that I had any choice – it was a compulsory one). I was then exposed to the brilliant ideas of double-entry accounting, first codified by Luca Pacioli in the late XV century. As a mathematician, I cannot overestimate the fact that double-entry bookkeeping is in fact an abstract formalized system. What’s even more impressive is that the bookkeepers are the ones who do negative numbers right!
