One thing about Bent Sigurdsen: when he says he'll call back, you know he'll call back. By the clock it wasn't much more than an hour later-although it felt like several times that-when the telecom beeped. I hit the appropriate key, and Bent's face filled the screen. He was out of the lab, virtually the only time I'd ever been on the phone with him when he was elsewhere. The background looked to be a window-wall with a view of the Sound and Bainbridge Island in the distance.
