Long-distance electromagnetic telegraph systems from 1820 onwards [a] used two or more wires to carry the signal and return currents. It was discovered by German scientist C.A. von Steinheil in 1836–1837, that the ground could be used as the return path to complete the circuit, making the return wire unnecessary. [2]
The "local" Earth/Ground electrode provides "system grounding" [13] at each building where it is installed. The "Grounded" current carrying conductor is the system "neutral". Australian and New Zealand standards use a modified protective multiple earthing (PME [ 14 ] ) system called multiple earthed neutral (MEN).
Grounding (metaphysics), a topic of wide philosophical interest; Grounding, a strategy for coping with stress or other negative emotions; Grounding in communication, the collection of mutual knowledge, beliefs, and assumptions; "common ground" Ground (electricity), a common return path for electric current

The kite experiment is a scientific experiment in which a kite with a pointed conductive wire attached to its apex is flown near thunder clouds to collect static electricity from the air and conduct it down the wet kite string to the ground.
Besides being dark and mysterious, crows are extremely intelligent birds. So smart, in fact, that it might be a little bit scary. Even though their brains are the size of a human thumb, their ...
Ufer discovered that concrete had better conductivity than most types of soil. Ufer then developed a grounding scheme based on encasing the grounding conductors in concrete. This method proved to be very effective, and was implemented throughout the Arizona test site.
