Falla, David – School Science Review, 2012
The nature of light and how it is affected by gravity is discussed. Einstein's prediction of the deflection of light as it passes near the Sun was verified by observations made during the solar eclipse of 1919. Another prediction was that of gravitational redshift, which occurs when light emitted by a star loses energy in the gravitational field…

Chernin, A. D. – Quantum, 1992
Presents basic facts about quasars as most powerful sources of radiation in the universe. Describes in detail the mirages and illusions that quasars generate and methods for their interpretation. Includes the notion of the gravitational lens and its relationship to twin quasars and the apparent measure of a quasar's bright jet tail moving faster…

Silver, Edward A.; Lane, Suzanne – Research in Middle Level Education Quarterly, 1995
Compared mathematical performance of middle school students in low-income communities involved in the QUASAR project to those of a demographically similar school and of a nationally representative sample. QUASAR mathematics instruction emphasizes reasoning, problem-solving, and understanding. Quasar students outperformed NAEP's disadvantaged urban…

Harrington, Sherwood, Comp. – 1984
This information packet on quasars consists of an introductory paper, four articles from "Mercury," a journal of the Astronomical Society of the Pacific, and a bibliography. Methods used to measure distances in the universe and the nature of quasi-stellar objects (QSO's), the name preferred by many workers in the field, are discussed in…

Lawrence, John K. – Mercury, 1980
Describes the gravitational lens effect and the chance of observing it. The use of stars, galaxies, or quasars is recommended for alignment with an intervening lens mass. (Author/SA)

Gordon, Kurtiss J. – American Journal of Physics, 1980
Provides information on the calculation of the redshift to blueshift ratio introduced by the transverse Doppler effect at relativistic speeds. Indicates that this shift should be mentioned in discussions of whether quasars are "local" rather than "cosmological" objects. (GS)

Smith, Margaret Schwan; Stein, Mary Kay – Mathematics Teaching in the Middle School, 1998
Focuses on the selection and creation of mathematical tasks, drawing on QUASAR's research on mathematical tasks and experiences with teachers and teacher educators. Presents examples of task analysis and issues that teachers should reflect on. (ASK)

Shu, Frank – Mercury, 1983
Presents a condensed version of textbook account of cosmological theory and principles. Topics discussed include quasars, general and special relativity, relativistic cosmology, and the curvature of spacetime. Some philosophical assumptions necessary to the theory are also discussed. (JM)
