About these units
Neutron Mass (mₙ)
The neutron is slightly heavier than the proton, with a mass of 1.67492749804 × 10⁻²⁷ kilograms. This subtle difference has profound implications: it allows neutrons to undergo beta decay outside the nucleus, transforming into protons, electrons, and antineutrinos. Neutrons play a crucial role in nuclear reactions, especially in reactors and stars. Their ability to penetrate atomic nuclei (due to lack of electric charge) makes them highly effective in initiating fission or fusion processes. The neutron mass helps determine nuclear binding energy and isotopic stability, shaping the entire periodic table.
Scruple (Apothecary) (s.ap)
The scruple is an old apothecary unit equal to 20 grains or 1.2959782 grams, originating in ancient Greek and Roman medicine. Apothecaries used scruples for compounding herbal remedies, powders, and tinctures long before standardized metric systems were adopted. Its size made it ideal for preparing early pharmaceuticals where doses needed to be accurate but not excessively granular. Over centuries, the scruple appeared in medical recipes, early scientific writings, and even medieval charms and remedies. Although obsolete today, replaced by milligrams and grams, the scruple is vital for historians studying early medical texts, pharmacy records, and classical-era scientific practices.
