Three freshman engineering students were sitting around talking between classes, when one brought up the question of who designed the human body. One of the students insisted that the human body must have been designed by an Electrical Engineer because of the perfection of the nerves and synapses. Another disagreed, and exclaimed that it had to have been a Mechanical Engineer who designed the human body. The system of levers and pullies is ingeniuos. The human body was designed by a Civil Engineer.
Mechanical engineers build weapons.
Civil engineers build targets. The wireless telegraph is not difficult to understand. The ordinary telegraph is like a very long cat. You pull the tail in New York, and it meows in Los Angeles. The wireless is the same, only without the cat.
