Kansas Is Flatter Than a Pancake

This was enjoyable:

The state is so flat that the off-the-shelf software produced a flatness value for it of 1. This value was, as they say, too good to be true, so we did a more complex analysis, and after many hours of programming work, we were able to estimate that Kansas’s flatness is approximately 0.9997. That degree of flatness might be described, mathematically, as “damn flat.”

Dunno, about 32 years ago I drove through KS on I-70. It had some rises and dips. Maybe I'm remembering eastern CO.

I want to see much ore of this kind of thing on HN!
