Spectral abscissa

In mathematics, the spectral abscissa of a matrix or a bounded linear operator is the greatest real part of the matrix's spectrum (its set of eigenvalues). It is sometimes denoted . As a transformation , the spectral abscissa maps a square matrix onto its largest real eigenvalue. (Wikipedia).

Teach Astronomy - Spectroscopic Binary

http://www.teachastronomy.com/ A spectroscopic binary occurs when the two stars are too close to be resolved by a telescope or when one member of the pair is too faint to be detected. The binary is observed in terms of a periodic Doppler shift of narrow spectral features, absorption lines

Refraction (1 of 5) What is Refraction? An Explanation

Refraction, A conceptual qualitative explanation. Refraction is the change in direction of a ray of light as it passes from one medium to another. The amount of refraction is determined by the index of refraction of the media and the angle of incidence. For light, refraction follows Snell
