Happy birthday and even happier physics-rich musical experimentation to beamjockey , the only ukulele player I know to have planted himself, supine, on the floor at the center of a geodesic dome in downtown Minneapolis, to enjoy the sounds his ukulele made in concert with said geodesic dome. Much happy physics, ballroom dancing, and good life to you in the next year!
And a belated birthday wish to a young man I've never met, buttonfish . I may never have met him, but I've seen his smile, and I know how loved he is, by mom, dad, and friends. May your year be filled with love and joy, little one.
