Text: The hazelnut is the nut of the hazel and therefore includes any of the nuts deriving from species of the genus Corylus, especially the nuts of the species Corylus avellana. It also is known as cobnut or filbert nut according to species. A cob is roughly spherical to oval, about 15--25 mm (0.59--0.98 in) long and 10--15 mm (0.39--0.59 in) in diameter, with an outer fibrous husk surrounding a smooth shell. A filbert is more elongated, being about twice as long as its diameter. The nut falls out of the husk when ripe, about 7 to 8 months after pollination. The kernel of the seed is edible and used raw or roasted, or ground into a paste. The seed has a thin, dark brown skin, which sometimes is removed before cooking.

Meanwhile, at camp, Leo creates plans for a ship that would sail to Greece, and the Hephaestus campers decide to undergo the project, appointing Leo as their new counselor. With part of his memory returned, Jason realizes that he is a son of Jupiter, a hero from a Roman counterpart camp to Camp Half-Blood called Camp Jupiter somewhere near San Francisco, California.

Text: It is useful to note that the mass-center is a fixed property for a given rigid body (e.g. with no slosh or articulation), whereas the center-of-gravity may, in addition, depend upon its orientation in a non-uniform gravitational field. In the latter case, the center-of-gravity will always be located somewhat closer to the main attractive body as compared to the mass-center, and thus will change its position in the body of interest as its orientation is changed.

Question: is center of gravity and center of mass the same?
