Planck Mass (mₕ)
The Planck mass, approximately 2.176434 × 10⁻⁸ kilograms, occupies a unique position in theoretical physics. Unlike particle masses, it is derived entirely from fundamental constants—Planck's constant, Newton's gravitational constant, and the speed of light. The Planck mass represents a mass scale where quantum mechanical and gravitational effects become comparable. Although enormous relative to subatomic particles (roughly the mass of a dust grain), it is considered "natural" in that it emerges from pure physics rather than empirical observation. In theoretical studies of black holes, quantum gravity, string theory, and early-universe cosmology, the Planck mass marks a boundary beyond which existing models require unification. It is a conceptual rather than practical unit, yet it provides a profound insight into the structure of physical law.
Gerah (Biblical Hebrew) (gerah)
A gerah, approximately 0.57 grams, is the smallest unit in the Hebrew weight system. 1 shekel = 20 gerahs Gerahs were used for minute quantities of precious metals or spices for ritual purposes. Biblical texts refer to gerahs in the context of sanctuary offerings and priestly duties. The gerah illustrates the fine-grained precision required for temple rituals and daily commerce in the ancient Near East.
