About these units
Atomic Mass Unit (u)
The atomic mass unit (u) is defined as exactly 1/12 the mass of a neutral carbon-12 atom, which makes it approximately 1.66053906660 × 10⁻²⁷ kilograms. This definition allows scientists to express atomic and molecular masses in a convenient, intuitive scale that aligns with the structure of the periodic table. By anchoring the unit to carbon-12, chemists and physicists gained a universal reference point that harmonizes molecular weight, relative isotopic abundance, and mass spectroscopy results. The atomic mass unit effectively normalizes the complexity of atomic masses into whole-number or near-whole-number values for most nuclei. In chemistry, u is indispensable for calculating molar masses, reaction stoichiometry, and isotopic compositions. It is also used across nuclear physics, astrophysics, and biophysics, demonstrating the universality of atomic-scale measurement.
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.
