What does this 'machine' have to do with 'science'? Science is assuming that our reality works like one giant machine, like one huge super computer if you want. What it then does, is trying to figure out how this machine works (by conducting experiments etc - see your course on social research methods). The reason why Fukuyama says that 'there is no science of public administration' is because we should not view our social and political reality as a machine at all. And that is because... there are problems in the relation between principals and agents.
