0:00.0	What's going on, everybody?
0:06.2	Welcome back to another episode of Iron Culture presented by Mass.
0:10.7	We only have one Eric today.
0:14.1	I'll let you decide if that's the best Eric, the worst Eric, your preferred Eric, but we've
0:18.6	only got one.
0:19.9	But that's okay, because I am joined by my colleague in arms at Mass,
0:25.8	not because he has big arms, but because he does have arms.
0:31.3	And he brings those arms to the table to welcome Dr. Zach Robinson.
0:37.0	And that is Dr. Mike Zerdos, Professor Mike Zerdos,
