...Stream obtained by a gadget called the Geomagnetic Electrokinetograph. GEK is a steel box full of vacuum tubes which analyzes electrical information from two electrodes trailed behind the ship. When the ship is swung 90° in one direction and then 180° in the other direction, the electrodes interact with the earth's magnetic field and so measure the motion of the water in relation to the sea's bottom...
...like a great, complex metropolis. The individual citizens (atoms) are organized into intricate groups like the people of the city. Some groupings (e.g., the three-atom molecule of water) are as small and tight as families. Others are larger, like all the workers in one factory.
