Outbreaks of contagious laughter (and mewing)

May 10, 2014

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).

A word 3½ hours long

February 11, 2014

If you’d asked me as a child how long it would take to speak the longest word in the English language, I’d have guessed a couple of seconds. Antidisestablishmentarianism would have come to mind, as the longest word in my pocket Collins dictionary at the time, or supercalifragilisticexpialidocious if “made-up” words were allowed.

Later I met other odd giants, like pseudopseudohypoparathyroidism and pneumonoultramicroscopicsilicovolcanoconiosis with their unmistakeably medical morphemes. All these words (Mary Poppins aside) are known chiefly for being very long – but with a bit of practice you could voice any of them in a single breath.

They’re mere pipsqueaks compared with some chemical names, which are probably not words in a strict sense but are impressively massive all the same – especially the protein Titin, aka connectin, whose chemical name begins Methionylalanylthreonylseryl… and goes on like that for 189,819 letters. In this remarkable video, Dmitry Golubovskiy reads it in its entirety. It takes him just over 3½ hours:

I didn’t watch the whole thing. After a couple of minutes I skipped ahead a bit, then watched the finale. His beard visibly darkens over the course of the performance, and he looks decidedly dazed at the end. The flowers wilt suddenly at 2:09:21 in a cut that suggests a bathroom break, or maybe a breather for sanity’s sake.

Hat-tip to @emordino for the video.
