Featured Article: Alternative Energy

Alternative energy is a term for any nontraditional energy form, source, or technology differing from the current popular forms, sources, or technologies. Today, it is generally used in the context of an alternative to energy deriving from popular fossil fuels and thus includes energy derived from such environmentally preferred sources as solar, water power, biomass, wind, geothermal, ocean thermal, wave action, and tidal action.

The term alternative energy also is used for energy derived from sources and technologies that do not involve the depletion of natural resources or significant harm to the environment. As such, it is used synonymously with "renewable energy" and "green power." While by most definitions there is substantial overlap between energy forms, sources, and technologies that fit into these three categories, and alternative energy often is applied to energy without undesirable environmental consequences or with lessened environmental impact, the three terms also have been delineated differently.

Popular Article: Love

The Kiss by Francesco Hayez, 1859
Popularly, Love is any of a number of emotions and experiences related to a sense of strong affection or profound oneness. Depending on context, love can have a wide variety of intended meanings, including sexual attraction. Psychologists and religious teachings, however, define love more precisely, as living for the sake of another, motivated by heart-felt feelings of caring, affection, and responsibility for the other's well-being.

The ancient Greeks described love with a number of different words: Eros was impassioned, romantic attraction; philia was friendship; xenia was kindness to the guest or stranger. Agape love, which the Greeks defined as unconditional giving, became the keystone of Christianity, where it is exemplified in Christ's sacrificial love on the cross. Some notion of transcendental love is a salient feature of all the world's faiths. "Compassion" (karuna) in Buddhism is similar to agape love; it is represented by the bodhisattva, who vows not to enter Nirvana until he has saved all beings. Yet love encompasses all these dimensions, eros as well as agape.
