In universities, they have a subject called Political Science. What is scientific about politics exactly? I'd like to see the experiments carried out to prove political theory during a political science lecture. What scientific equations are there related to the field of politics? Do they work, could I construct the next ruling party of the UK with these political science equations?

Seriously, I'd like your thoughts, arguments for and against this subject, and, if possible, an answer to what makes politics a science?
