A book called Open Circuits had this strunning picture of a cable split down its width. The beautiful arrangement inside caught my attention and it got me thinking how Biologists might approach the problem of resolving its function. In other words, its obviously a cable but can you derive what the cable is used for?

The subject (a cable), while not biological, is a good demonstration precisely because we are not electrical engineers. This little mental exercise is a rip-off of “Can a Biologist fix a radio” but its still interesting none the less.
