Met`a*cen"ter or; Metacentre, n. Etym: [Pref. meta- + center.] (Hydrostatics)
Definition: The point of intersection of a vertical line through the center of gravity of the fluid displaced by a floating body which is tipped through a small angle from its position of equilibrium, and the inclined line which was vertical through the center of gravity of the body when in equilibrium.
Note: When the metacenter is above the center of gravity, the position of the body is stable; when below it, unstable.

Coffee dates back to the 9th century. Goat herders in Ethiopia noticed their goats seem to be “dancing” after eating berries from a particular shrub. They reported it to the local monastery, and a monk made a drink out of it. The monk found out he felt energized and kept him awake at night. That’s how the first coffee drink was born.
