Modern Physicists and Sailing

Lubos Motl with his blog The Reference Frame prides himself to be a physicist, with special expertise in string theory. In his last post, he shows complete ignorance about the physics of sailing which puts him in the same league as the Stephen Hawking he is criticizing for being illiterate about basic physics of planetary climate.

How can it be that physicists of today, who are viewed by the physics community (like Hawking) or are viewing themselves (like Motl) as carriers of deepest insight into the deepest mysteries of physics, can be totally ignorant about basic simple physics?

PS Lubos accepts a comment from me on his post, a rare event, pointing to the new theory of sailing and flying I have developed with Johan Hoffman and Johan Jansson. It will be interesting to see if Lubos will read and learn, or if the material will be too difficult for him to grasp...
