Math is hard

I finished a good scifi read on the long plane ride east. It was Nancy Kress's Probability Moon. Like many scifi writers, Kress has a theme to which she returns in most books. Her hot topic is evolution and human genetic change (natural or manipulated.) In this book, Earth people crossing the stars (she avoids violating relativity, don't worry) find a society where any violation, in thought or otherwise, against the societal moral code causes crushing headaches. So there is little crime, but also limits on diverse approaches to problem solving. The plot hinges on an anthropological study of these people that takes place in the middle of a war that Earth is losing. At the very end, when I was most tired, she got the most difficult in her use of quantam mechanics. But don't let that scare you, it wasn't that hard. Not as hard as this for example. If you really want some headaches check the related wiki.
