Markov Chains are wondrous little things that allow you to make arbitrary calculations at a future time and there’s a bunch of matrices involved.  Today we had a quiz on them and after the first few questions we hit one where for once there were actually numbers.  Not letters, honest to God numbers.  In a college math class, what nerve!  Needless to say we were all confused as shit, as each person reaches that point, we looked at each other, and looked at the paper staring at the ‘digits’ and said “numbers, what do I do with these?<– Interrobang should be here“  I wanted to raise my hand and say “none of these numbers contain a variable”.
