Some formulae are given to aid understanding, but this is not one of those courses where you need a mathematics degree to follow it. The course will sharpen your ability to think critically and not take things for granted: in this age of uncontrolled algorithms and fake news, these skills are more important than ever. There will be mini-quizzes with feedback along the way to check your understanding.
