... Among the objectives of Principal Components Analysis are the following. dimensionality reduction; љ . the determining of linear combinations of variables; љ . ... identification of groups of objects or of outliers. ... Finding a set of principal axes allows the objects to be adequately characterised on a smaller number of (artificial) variables. ... Reduction of dimensionality is practicable if the first new axes account for approximately 75 % or more of the variance. ...

Classroom Activity: Making a Rainbow . ... When white light from the Sun or a light bulb passes through a prism, the light splits into its component wavelengths. ... Red, blue, green colored filters - if possible, cut 1x4-inch pieces of the filters for each student . ... Many students have the misconception that filters somehow dye the light a certain color. ... Younger students can draw the rainbow and make up a mnemonic for remembering the order of the colors (such as, ROY G. BIV). ...

We present the numerical simulations for an electron-beam-driven and loss-cone-driven electron cyclotron maser (ECM) with different plasma parameters and different magnetic field strengths for a relatively small region and short time-scale in an attempt to interpret the recent discovered intense radio emission from ultracool dwarfs. ... A wide frequency band should therefore be covered by future radio observations. ...

GROUPS OF ALGEBRAIC TRANSFORMATIONS OF AFFINE VARIETIES FINAL REPORT FOR THE THREE YEARS KARINE KUYUMZHIYAN 1. ... The latter is an algebraic variety with the given field of rational functions and an infinitely transitive regular action of a group of algebraic automorphisms generated by unipotent algebraic subgroups. ... Quotient groups. ... Since over R there exist irreducible non-connected varieties, we cannot have even one-transitivity of any connected group of automorphisms. ...

... The material in "From Stargazers to Starships" meets several important requirements of the national standards. Pages cited below are from National Science Education Standards National Academy Press, Washington 1995. ... For example: the sections on astronomy not only describe calendars and sundials (including their construction), but also the astronomy of the ancient Greeks, including two different ways in which ancient Greeks estimated the distance to the Moon. ...

The three panels show different components of near-infrared background light detected by the Hubble Space Telescope in deep-sky surveys. ... When all the stars and galaxies are masked, the background signals can be isolated, as seen in the second and third panels. The middle one reveals intrahalo light from rogue stars torn from their host galaxies, and the panel on the right captures the signature of the first galaxies formed in the universe. ...

The notion of ions first arose in chemistry. In the 19th century it was well known that water in which salts were dissolved (or acids, or bases) conducted electricity, and that an electric current could separate such dissolved materials into their components. ... In 1898 Ernest Rutherford noted that the radiation seemed to contain two electrically charged components of opposite signs, steered by a magnet in opposite directions--positive "alpha rays" and negative "beta rays." ...
