The isospin and strangeness determine this quantity for hadrons in a formula developed by Okubo and Gell-Mann. When this quantity (-5[1])equals (-5[1])zero, the Dirac equation reduces to the Weyl [vile] equation. Spontaneous symmetry breaking creates bosons with a zero value of this quantity according to Goldstone’s (-5[1])theorem. In a formula named for this quantity, Coulomb, asymmetry, and pairing terms are used to represent the liquid drop model; that (10[1])(*) “semi-empirical” formula is used to calculate the nucleus’s namesake “defect” in this (10[1])quantity. A Millennium (10[1])Prize problem involves determining whether Yang-Mills theory has a “gap” in this quantity. Kinetic energy equals momentum squared over 2 times this quantity. For 10 points, Albert Einstein stated (10[1])that what quantity equals (-5[1])energy over the speed of light squared? (10[4])■END■
