Over the years of working in IT, I have developed a phobia about cords. USB cables, power cords, headphones ... whatever. My heart starts racing and my breathing becomes labored whenever I have to deal with them. Why? Because they always end up tangled in ways that seem to defy common sense.
Once, at a former job, the power cord of my computer knotted itself (completely on its own) around the leg of my desk. When I pulled the desk out to retrieve a fallen object, the cord yanked the outlet out of the cubicle wall, which caused a short that, in turn, killed power to the first two floors of the library. As if that wasn't bad enough, the same thing happened two months later.
How can two cables lying peacefully under my desk one day end up in some sort of triple-bowline figure-eight double-hitch knot the next day? I have long suspected that evil little gnomes are responsible.
But I am pleased to learn that it doesn't just irritate me. An article from Science News Online reports scientists, prompted by similar frustrations, have conducted experiments that demonstrate surprisingly complex knots can arise in strings and cords after subjecting them to very little agitation.
By tumbling a string of rope inside a box, biophysicists Dorian Raymer and Douglas Smith have discovered that knots—even complex knots—form surprisingly fast and often. The string first coils up, and then its free ends swivel around the other coils, tracing a random path among them. That essentially makes the coils into a braid, producing knots, the scientists say.
This was not the first such experiment. The article explains:
For example, in 2001 Belmonte and his collaborators showed that a hanging chain ... tended to knot up when shaken. In 2006, a team led by physicist Jens Eggers of the University of Bristol in England got a ball chain to form knots by setting it on a vibrating dish.
Once again, science disproves superstition. But I'm still blaming the gnomes for stealing all my underpants.
One of the main reasons Amy and I moved to Seattle was for the climate of the Pacific Northwest. I had never known a life without four seasons before relocating, and I am constantly amazed at the difference a more temperate environment makes in overall quality of life. Not everyone can handle the rain and overcast skies throughout the winter, but to me, as long as I never have to feel the liquid on my eyeballs freeze in the winter or walk around the summer drenched in sweat and searching for air conditioning, I'll never leave.
