I know the idea of ones and zeros has been talked about before in both class and in the blog, though the only instance I can think of off the top of my head is regarding Roger Mexico being the in-between to Poinstman's ones and zeros. On page 410 the idea comes up again, this time relating to personal peace. "We live lives that are waveforms constantly changing with time, now positive, now negative. Only at moments of great serenity is it possible to find the pure, the informationless state of signal zero." There are several very interesting things about this quote, one of which is the continuation of the one-zero theme. Also, I find it really strange that he would say that serenity=informationless, like ignorance is bliss. It's also funny because Pynchon goes on to say "Closest to zero among them all, perhaps, was the African Enzian"...I'm not entirely sure what the significance is of Enzian being "at peace" but I feel like there must be something.

On a side note, I randomly came across this website while doing a search for 'signal zero'. It might be helpful for characters etc. especially for those without the companion? I haven't looked around much but I thought I'd let people know just in case, especially since there seems to be a lack of websites about Gravity's Rainbox http://gravitys-rainbow.pynchonwiki.com/wiki/index.php?title=GR_Alpha_Nav
