My very first post, about a web page published by the University of Wisconsin Madison Physics Department, has finally become obsolete.
Hurray!
After I contacted the chair of the department by email, I head back from the person in charge of the page. He explained the constraints placed on content by their intended audience, and I suggested they merely not mention bicycles or motorcycles at all. He agreed, and now there is one fewer source of bad motorcycle science on the internet.
Only a couple dozen to go.
