Previous Episode: S2E9 - Project Daedalus

This episode really didn't stick the landing for us. David wants to know why anthropologists are building time machines just to test their pet theories. Zach teaches a class on time travel paradoxes, complete with examples involving a German child in the early 20th century. Not to poke fun, but if we designed ocular scanners, we would also put needles in the eyepieces.
