Hi everyone! I’m James Matthew Miraflor, data science and complex systems enthusiast, graduate student currently finishing my MS in Computer Science (Scientific Computing) and MA Economics at the University of the Philippines Diliman, activist, and blogger.:-)

A mathematician, a theoretical economist, and an econometrician are asked to find a black cat (who doesn’t really exist) in a closed room with the lights off. The mathematician gets crazy trying to find a black cat that doesn’t exist inside the darkened room and ends up in a psychiatric hospital. The theoretical economist is unable to catch the black cat that doesn’t exist inside the darkened room, but exits the room proudly proclaiming that he can construct a model to describe all his movements with extreme accuracy. The econometrician walks securely into the darkened room, spends one hour looking for the black cat that doesn’t exits and shouts from inside the room that he has caught it by the neck.
From here.
