Anne is a "Strange Quark"

Wow! I won the “strange quark” (2nd place) award in a science writing contest, hosted by Three Quarks Daily, for blogging about the Mississippi River, floods, levees, and the illusion of control. As I wrote in the comments at 3QD: Wow! I never thought I’d actually win something for writing …

Anne in the news

Flooding along the Mississippi River Last week, I wrote a post for the Scientific American Guest Blog on “Levees and the Illusion of Flood Control,” about the ways that while levees around individual communities may be good, the systematic leveeing of entire waterways is a bad long-term strategy.

Snowmelt in the headwaters, combined with weeks of heavy rains in the middle reaches of the river basin, have pushed the system to its …

This divide is not so much a high point in the landscape, but a just-not-quite-as-low area.
