	What is a State Vector?
		A state vector is a set of data telling exactly where the shuttle is in its orbit in space.
		State vectors are as important to the ground support personnel as they are to the shuttle itself.
		The form of a state vector is just a way of identifying which set of orbit parameters is being used to define the orbit.

		First, he found that the orbits of the planets in our solar system are elliptical, not circular (or epicyclic), as had previously been believed, and that the sun is not located at the center of the orbits, but rather at one focus.
		Second, he found that the orbital speed of each planet is not constant, as had previously been thought, but rather that the speed of the planet depends on the planet's distance from the sun.
		In the case of gravity, Newton's law of universal gravitation states that the force is proportional to the inverse square of the distance:

	The influence of Orbit precision in the quality of ERS SAR Interferometry (Site not responding. Last check: 2007-10-21)
		The difference introduced by the interpolation should be minimized with the use of multiple state vectors equally spaced in time, which will ensure that every certain period the orbit data used is close to the satellite orbit, and that the errors due to propagation are cancelled.
		Images were processed using restituted and precise state vectors in the two modes of operation: propagating from one single state vector and propagating and interpolating multiple state vectors.
		When using multiple state vectors no obvious error is introduced by the interpolation although if their position differs too much from the real one the number of residual fringes can increase.

	*OPTIMIZATION
		Active orbitals are transformed to natural orbitals and the CI-vectors are counterrotated such that the CI states do not change.
		The inactive and secondary orbitals are transformed to Fock type orbitals (corresponding to canonical orbitals for closed shell Hartree-Fock).
		For RAS wave functions the active orbitals are only transformed within their own class (RAS1, RAS2, or RAS3) as the wave function is not invariant to orbital rotations between the classes.

	Pauli exclusion principle Summary
		There are five orbitals with n=2: a 2s orbital with n=2, l=0, m=0, containing two electrons; three 2p orbitals, of slightly higher energy, for which n=2, l=1, and m has the values -1, 0, and +1; each of these p orbitals may contain two electrons; six electrons may thus be accommodated in these p orbitals.
		There are nine orbitals with n=3: a 3s orbital with two electrons; three 3p orbitals of slightly higher energy that may contain a total of six electrons; and five 3d orbitals with n=3, l=2, and m has values of -2, -1, 0, +1, and +2.

	CelesTrak: "Orbital Coordinate Systems, Part I"
		Knowing that orbital element sets are generated by fitting observations to a trajectory based upon a particular orbital model is the second of our key aspects.
		A state vector is a collection of values (states) that if known, together with the state transformation rules (how the state vector changes over time), the state vector for any past or future time can be computed.
		Now, while state vectors are normally used with numerical integration models for highly accurate calculations, Keplerian orbital elements are used for the vast majority of orbital predictions.

	Orbital elements - Wikipedia, the free encyclopedia
		Further, when working with real satellites, there are many forces acting on the satellite which can cause small changes in any of the orbital elements.
		(Sometimes the epoch itself is considered an orbital element.) Other orbital parameters, such as the period, can then be calculated from the Keplerian elements.
		It is also possible to describe an orbit using just five elements at an epoch by making some assumption about the sixth element, such as specifying that epoch will only occur when the Mean anomaly is zero.

	Consciousness and Quantum Mechanics
		So, instead of describing the orbital state by the electron's position, each of these orbits is represented by a wave function, which is the mathematical description of the wave of possibility for the electron to appear.
		Thus, the state vector represents a potential for the particles to be found in any of the four possible states we can actually observe.
		In this case, we are forced to say that the cat is in a state similar to that of the atom: it is not actually dead or actually alive, but just in a state of being potentially both dead and alive.

	NSS 1740.14 - August, 1995
		Collision with orbital debris is a hazard of growing concern as historically accepted practices and procedures have allowed man-made objects to accumulate in orbit.
		NASA Management Instruction (NMI) 1700.8 states "NASA's policy is to employ design and operations practices that limit the generation of orbital debris, consistent with mission requirements and cost-effectiveness." The NMI requires that each program or project conduct a formal assessment for the potential to generate orbital debris.
		As required by NMI 1700.8, "Policy to Limit Orbital Debris Generation," the debris assessment covers two broad areas: the potential for generating debris during normal operations or malfunction conditions, and the potential for generating debris by collision with space debris (natural or human-generated) or orbiting space systems.

	Biology 750: UV / Visible Spectroscopy
		If light striking a molecule in State 1 has an energy equal to the difference in energy between molecular State 1 and State 2, there is a probability that a molecule will absorb a photon and jump to the higher energy state, State 2.
		Absorption of a photon of light has a high probability of occuring when the orientation of the electric vector of the light wave, E, is oriented in a direction which will induce a movement of an electron from one molecular orbital to another oribital of higher energy.
		Another way of stating this is to say that E is oriented along a Transition Dipole of the molecule.
