Photo challenge: Dancer on the door

On the Daily Post blog, Cheri Lucas Rowlands has invited WordPress users to share photos of doors as part of a photo challenge. For a break from my usual subjects, I’m joining in with a repost from 2010, just because.

Doors, Cheri writes, can be a source of beauty in the mundane, and in this case I love how an old building with a certain mournful, dilapidated charm was briefly transformed by an anonymous street artist into something quite magical.

Outbreaks of contagious laughter (and mewing)

Robert Provine’s book Laughter: A Scientific Investigation has a very interesting chapter on contagious laughter. This curious phenomenon has long been exploited in such items as laugh boxes and musical laugh records, as well as being central to laugh tracks (from Ancient Rome to modern TV) and churches of “holy laughter”.

Contagious laughter is, of course, also an everyday occurrence, spreading directly from person to person in normal interaction. But even this activity can become abnormal, when for instance instead of dying down it persists and spreads over a wide area, as happened in the Tanganyika laughter epidemic (though it wasn’t just laughter).
