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.
Tetradrachma (Biblical Greek) (tetradrachma)
A tetradrachma weighed about 17 grams, equivalent to four drachmas. It became one of the most widely circulated silver coins in the ancient world, especially under the Athenian empire. Athenian tetradrachms, often stamped with the iconic owl design, were standardized, highly trusted, and circulated across the Mediterranean as an international currency. Although now primarily of numismatic interest, tetradrachms are key archaeological artifacts, illuminating trade networks, political authority, and artistic expression.
