The following example shows the harmonic series for the fundamental pitch C. (Asterisked notes are noticeably out of tune with the tempered chromatic scale, which contains 12 equal semitones.)

health law: Termination of pregnancy: …was labeled by Congress as “partial-birth” abortion (a surgical abortion in which a late-term fetus is removed through the cervix). In a 5–4 opinion, the Supreme Court permitted Congress to entirely outlaw this procedure on the basis that Congress could determine that its use undercut medical ethics and that other…

Many fibres, such as PET, require that a hot-drawing step follow the spinning process fairly soon, or they will become brittle.…

ethnography: This method, called participant-observation, while necessary and useful for gaining a thorough understanding of a foreign culture, is in practice quite difficult. Just as the anthropologist brings to the situation certain inherent, if unconscious, cultural biases, so also is he influenced by the subject of his study. While…

particle accelerator: Colliding particles: More common yet have been particle-antiparticle colliders. An antiparticle has opposite electric charge to its related particle. For example, an antielectron (or positron) has positive charge, while the electron has negative charge. This means that an electric field that accelerates an electron will decelerate a positron moving in the same…

charge conjugation, in particle physics, an operation that replaces particles with antiparticles (and vice versa) in equations describing subatomic particles. The name charge conjugation arises because a given particle and its antiparticle generally carry opposite electric charge. The positive
