Studying neuron reactions leads to directly implementable, and highly
useful, mathematical equations. All hail our flying droid overlords!

> Intriguingly, the algorithm doesn’t work nearly as well if any one

> and Brinkworth don’t know why. Because the parameters are in constant
> feedback-driven flux, it produces a cascade of non-linear equations

> system almost as complicated as the insect’s,” said O’Carroll. “That’s
> one of the fascinating things here. It doesn’t necessarily lead us to
> a complete understanding of how the system works, but to an
> appreciation that nature got it right.”
