About these units
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.
Bekan (Biblical Hebrew) (bekan)
The bekan (or beka) is a half-shekel unit, approximately 5.6 grams. It appears in the Hebrew Bible as the required contribution for the census tax, symbolizing equality among contributors regardless of wealth. As a practical unit, the beka was useful for small-scale offerings, jewelry, and silverwork. Its precise half-shekel value made it easy to incorporate into the larger Hebrew weight structure. The bekan highlights how weights were intertwined with religious observance and communal obligations in ancient Israelite society.
