Apsis

An apsis (Greek: ἁψίς; plural apsides /ˈæpsᵻdiːz/, Greek: ἁψίδες) is an extreme point in an object's orbit. The word comes via Latin from Greek and is cognate with apse. For elliptic orbits about a larger body, there are two apsides, named with the prefixes peri- (from περί (peri), meaning "near") and ap-, or apo- (from ἀπ(ό) (ap(ó)), meaning "away from") added to a reference to the thing being orbited.

A straight line connecting the pericenter and apocenter is the line of apsides. This is the major axis of the ellipse, its greatest diameter. For a two-body system the center of mass of the system lies on this line at one of the two foci of the ellipse. When one body is sufficiently larger than the other it may be taken to be at this focus. However whether or not this is the case, both bodies are in similar elliptical orbits each having one focus at the system's center of mass, with their respective lines of apsides being of length inversely proportional to their masses. Historically, in geocentric systems, apsides were measured from the center of the Earth. However, in the case of the Moon, the center of mass of the Earth–Moon system, or Earth–Moon barycenter, as the common focus of both the Moon's and Earth's orbits about each other, is about 74% of the way from Earth's center to its surface.

Apogee (disambiguation)

Apogee, or more formally apsis, is the point, in an elliptical Earth orbit, of greatest distance from the Earth. Ballistic apogee is the highest altitude in the trajectory of a projectile.

List of The Incredibles characters

The following is a list of fictional characters from the 2004 Disney/Pixar animated film The Incredibles and related media.

The Incredibles

Mr. Incredible

Robert "Bob" Parr (a.k.a. Mr. Incredible) (voiced by Craig T. Nelson), possesses tremendous strength and durability. He also has enhanced senses. He is married to Helen Parr, the superheroine known as Elastigirl, and they have three children together: Violet, Dash, and Jack-Jack.

Bob found forced retirement difficult, and often had to cheat his way out of the house on Wednesdays so that he could continue his superheroics. He was shocked to discover that his "Number 1 fan", Buddy Pine, had reformed himself as the villain Syndrome after Mr. Incredible had squelched Pine's wish to be his ward in an attempt to protect him, and it was not until Syndrome threatened the family's lives that Bob realized that his family was his "greatest adventure".

His red superhero suit, designed by Edna Mode, appears to have the same level of durability as Mr. Incredible himself. In his prime, Mr. Incredible drove a gadget-laden car, the Incredibile, not unlike the ones driven by James Bond or Batman. The silhouette of a newer version of the Incredimobile for the entire family is seen in the end credits, and makes a full appearance in the comic series.

Apogee (album)

Apogee is the second full-length album by stoner metal band Bongzilla. The album was released in May 2000 by Ritual Records, and re-released in 2004 by Relapse Records. It contains three songs recorded in the studio and four recorded at a live concert.
