"Yeah, I was talking with—it's Chase, right?" Avram said, glancing down the table towards the guy that Pam had fingered earlier as being the one who'd made the map. "We were talking on the network about collecting some more data to make the map more accurate, anyway. If people want to volunteer to help survey the edges of town, that'd be cool. Bad news is that with no technical instruments for measuring electric fields, and not knowing where the sources are, and since the terrain around here is so uneven...I can only think of one method for figuring out the limits of the barrier and that method is gonna suck. Like I might be guilty of linear thinking there, someone else might come up with a better strategy," he admitted. He'd been turning over the problem in his head for awhile, but mathematicians weren't known for practicality and he was sure that there was some obvious method that he just wasn't seeing. "But people should probably assume that they're gonna get shocked if they volunteer, anyway. All the fun of measuring things, with the added bonus of pain, what's not to like?"
