Blog post: ajb: Assume spherical sheep in vacuum...

Scientists have now used GPS to uncover the rules that describe how sheepdogs are able to herd sheep.

Strömbom et al [1] have shown that there are surprisingly few rules here; in fact they suggest just two rules.

 

The sheepdog learns how to make the sheep come together in a flock.

Whenever the sheep are in a tightly knit group, the dog pushes them forwards.

 

The sheepdogs make the most of what is know as "selfish herd theory", that is the tendency of a given sheep to want to be near the centre of the flock when under threat.

 

There is a Welsh connection here. One of the authors, Dr. A. King is based at Swansea University, which is where I studied for my undergraduate degree.

 

Now, anyone know any good jokes about Welsh people and sheep? Can't say that I have herd many...
