Mirror-image asymmetry: An introduction to the origin and consequences of chirality
by James P Riehl
appears in today's issue (No 14) of Chemistry & Industry, pp28-29.
Here's a snippet:
I was intrigued to learn that the historic Dutch windmills, like so many other things, owe their unanimous chirality to the fact that they were designed for right-handers. Conversely, the plane of the Wright brothers is achiral, as it has two propellers that are mirror-images of each other.
All in all this is a laudable effort by a long-serving practitioner of science to popularise his field, and a book that can enlighten chemists and lay people alike.
The review should show up here soon.

PS solution to the windmill conundrum: operating the windmill involves climbing up the blades and unfolding the sails. All Dutch windmills are built such that you can do that with your right hand.
