I had lunch with David K. today at Hokkaido restau­rant in the heart of the Japan­ese dis­trict, near Rue St. Anne. The chefs are pretty pro­fi­cient in han­dling fire as they flash-cook your meal before your eyes. My favorite at the moment is Yak­i­udon, a deli­cious mix­ture of rice noo­dles, veg­gies and thin slices of steak.

David is a the­o­ret­i­cal physi­cist deal­ing with Super­sym­me­try, Par­ton Show­ers, String The­ory, and the like. Besides his pas­sions for physics, he is an expert on optics, imagery and the capac­ity and lim­its of soft­ware appli­ca­tions that cor­rect the many types of dis­tor­tions caused by cam­era lenses. This makes for great talk and per­haps even a good busi­ness model.
