a glass thimble that birthed humans and held the universe's smallest impossible experiments

means A thin, finger-shaped glass tube, open at one end and rounded at the other, used in laboratories to hold, mix, or heat small amounts of a substance.

from A plain compound of two old, ordinary words doing extraordinary work. "Test" arrived in English from Old French 'test', meaning a small earthen pot — itself from Latin 'testum', a clay vessel or lid (a cousin of 'testa', a shell or potsherd). Alchemists used such a pot, called a 'test', to assay metals, so 'test' came to mean a trial or examination. "Tube" comes from Latin 'tubus', a pipe. Stitched together, the term names exactly what it is — a tube for testing — and entered scientific English in the 19th century as chemistry equipped its glassware.
