The Thinker () is a bronze sculpture by Auguste Rodin, usually placed on a stone pedestal. The work shows a nude male figure of heroic size sitting on a rock with his chin resting on one hand as though deep in thought, often used as an image to represent philosophy.

There are various other versions, as well,
to cathodically protect metals that are exposed to sea water. A zinc disc attached to a ship's iron rudder will slowly corrode while the rudder stays intact. Similarly, a zinc plug attached to a propeller or the metal protective guard for the keel of the ship provides temporary protection.
With a standard electrode potential (SEP) of −0.76 volts, zinc is used as an anode material for batteries. (More reactive lithium (SEP −3.04 V) is used for anodes in lithium batteries ). Powdered zinc is used in
