Possible definitions for xmases

Maes
Dutch painter. A native of Dordrecht, he went to Amsterdam c.1650 to study with Rembrandt. Before his return to Dordrecht in 1653 he painted a few life-size Rembrandtesque genre scenes. From 1655 to 1660 he painted smaller domestic scenes, usually of women spinning, eavesdropping, reading the Bible, or cooking. In 1673 he moved permanently to Amsterdam and devoted himself to portraiture, abandoning intimacy and the deep glowing colors characteristic of Rembrandt for elegance and cooler tones reminiscent of A. Van Dyck. He was a prolific painter and his portraits enjoyed great success.


maser
Device that produces and amplifies electromagnetic radiation in the microwave range of the spectrum. The first maser was built in 1951 by C. Townes. Its name is an acronym for "microwave amplification by stimulated emission of radiation." The wavelength produced by a maser is so constant and reproducible that it can be used to control a clock that will gain or lose no more than a second over hundreds of years. Masers have been used to amplify faint signals returned from radar and communications satellites, and have made it possible to measure faint radio waves emitted by Venus, giving an indication of the planet's temperature. The maser was the principal precursor of the laser.


mass
Quantitative measure of inertia, or the resistance of a body to a change in motion. The greater the mass, the smaller is the change produced by an applied force. Unlike weight, the mass of an object remains constant regardless of its location. Thus, as a satellite moves away from the gravitational pull of earth, its weight decreases but its mass remains the same. In ordinary, classical chemical reactions, mass can be neither created nor destroyed. The sum of the masses of the reactants is always equal to the sum of the masses of the products. For example, the mass of wood and oxygen that disappears in combustion is equal to the mass of water vapor, carbon dioxide, smoke, and ash that appears. However, A. Einstein's special theory of relativity shows that mass and energy are equivalent, so mass can be converted into energy and vice versa. Mass is converted into energy in nuclear fusion and nuclear fission. In these instances, conservation of mass is seen as a special case of a more general conservation of mass-energy. See also critical mass.

Celebration of the Eucharist in the Roman Catholic church. It is considered a sacramental reenactment of the death and resurrection of Jesus as well as a true sacrifice in which the body and blood of Jesus (the bread and wine) are offered to God. It is also seen as a sacred meal that unifies and nourishes the community of believers. The mass includes readings from Scripture, a sermon, an offertory, a eucharistic prayer, and communion. The rite was greatly changed after the Second Vatican Council, notably in the adoption of vernacular languages in place of Latin. See also sacrament, ...
