  Plane (mathematics) - Wikipedia, the free encyclopedia
In mathematics, a plane is a fundamental two-dimensional object.
The topological plane, or its equivalent the open disc, is the basic topological neighbourhood used to construct surfaces (or 2-manifolds) classified in low-dimensional topology.
The topological plane is the natural context for the branch of graph theory that deals with planar graphs, and results such as the four color theorem.

 AllRefer.com - plane (Mathematics) - Encyclopedia
An example of a plane, or more exactly of a bounded portion of a plane, is the surface forming one face, or side, of a cube.
A plane is determined, or defined, by any of the following: (1) three points not in a straight line; (2) a straight line and a point not on the line; (3) two intersecting lines; or (4) two parallel lines.
For a given plane in space, a line can either lie outside and parallel to it, intersect the plane in a single point, or lie entirely in the plane; if more than one point of a straight line lies in the plane, then the entire line must lie in the plane.

A rocket-powered aircraft or rocket plane is an aircraft that uses a rocket for propulsion, sometimes in addition to jet engines.
The only rocket plane ever to be mass-produced was the Messerschmitt Me 163 in 1944, one of several German World War II attempts at rocket-powered aircraft.
The first truly successful rocket plane was the North American X-15, which was used for several years and eventually broke Mach 6.0.

The Oriental Plane is first mentioned, among English writers, by William Turner, "the father of English botany," in his "Herbal," printed at Cologne in 1568; and in 1596 John Gerard had it growing in his garden in Holborn, the history of his specimen being subsequently given by him in his "Herball" (1597), p.

To the student of philosophy the Plane must always be associated with the groves of the Academe, in which walked the earliest of the peripatetic philosophers.

Older planes are particularly susceptible to metal fatigue, caused by the gradual weakening of metal as it bends and twists during years of use.
The plane, a C-130 propeller plane that had been converted for use by the Forest Service, was built in 1957.

 Inclined Plane [encyclopedia]   (Site not responding. Last check: 2007-10-21)
An inclined plane is a ramp that reduces the force necessary to overcome the force of gravity when changing the elevation of mass in a gravitational field.
The ramp or inclined plane was useful in building early stone edifices, in roads and aquaducts, and military assault of fortified positions.
Detailed understanding of inclined planes and their use helped lead to the understanding of how vector quantities such as forces can be usefully decomposed and manipulated mathematically.

 Invariable Plane · Astrological definition of Invariable Plane · Astrology Encyclopedia
The Solar System possesses two fixed planes: that of the Solar Equator; and the Invariable plane - a central plane of the Solar System discovered by Laplace, which, passing through its center of gravity at a mean inclination of about 1°35' to the Ecliptic, is independent of the mutual perturbations of the planets.
As a result of this residue, the nodical line at which the orbit plane of each planet intersects the invariable plane, is displaced backward, in a precessional motion of the whole orbit plane.
The period of the orbital precession of the Ecliptic on the Invariable Plane is indeterminate, since the minimum inclination of the Ecliptic to that plane is 0°0'0".

By showing some of the symmetries of the projecive plane of order 3, we can see what some of the elements of the automorphism group of the space are.
Now that we have seen projective planes of orders 2, 3 and 4, we are curious as to what orders exist corresponding projective planes.
In the case of projective planes of order 9, there are four such non-isomorphic projective planes.

The selection of different planes is an expansive and diverse grouping.
While flying single engine Cessnas or Pipers is always a blast, some pilots may want to try out their wings with airliners that are more "high-tech." To this end, Laminar has included a nice selection of military planes, including VTOL jets like the Harrier.
Were you to try and take off from a smaller community airstrip using a large 747 or other jumbo jet, you would quickly discover why certain planes have a strict minimum on runway length.

 Making a LA plane? - Sawmill Creek
The key to success is a sharp iron and a reasonably well tuned bench plane, but if you are new to handplanes, I'd start with a good quality bench plane instead of a block plane, since you can get a bit more mileage out of it over a LA block plane.
Making LA wood planes is extremely difficult, this is why I mention that you may just want to make a regular bench plane instead if you aren't interested in buying a metal plane.
The plane body has a metal thread insert into which the bolt is screwed to hold the blade down.

Of course, to explain or work with ideas using the term plane, we must imagine objects with similar characteristics as planes, even though they may not be perfect.
These lines are parallel to each other because they are on the same plane (the surface of this piece of paper) and they are the same distances apart.
Note: This is not to say that you cannot draw lines that are not in the same plane and not parallel, but the lines we draw in our work usually are.

I decided to check the manifest of those killed on Flight 77, which informed me that there were  only 50 passengers and 6 crew listed.  Apparently, there were families who didn't want to list the names of their loved ones killed on the flights of 9/11.
Could it be that the plane deliberately targeted an area of the Pentagon where someone knew there wouldn't be as many people because of the construction?  But that still doesn't answer the question about why the lawn was not torn up.
