Engineers use feedback loops — typically negative feedback is more useful, but positive feedback is needed for oscillators.

A very important concept in electronics is that of negative feedback. This is an extremely important concept to grasp, as great many electronic systems exploit this principle for their operation and ...

Maintaining perfect stability through negative feedback is a basic element of electrical circuitry, but it’s been a mystery how cells could do it — until now. Mustafa Khammash’s small Lego robot is ...

“The only way to discover the limits of the possible is to go beyond them into the impossible.” – Arthur C. Clarke Even worse: some of these laws go back decades with little to no effort to improve ...
