the energy to lift an apple one meter, named after a brewer who chased heat
means A joule is the standard scientific unit of energy or work, equal to the energy expended moving an object one meter against a force of one newton (or, more graspably, about the effort to lift a small apple one meter up).
from Named for James Prescott Joule, the 19th-century English physicist who—funded in part by his family's brewing fortune—obsessively measured how mechanical work turns into heat, famously paddling water to warm it by fractions of a degree. His experiments helped establish the conservation of energy, and the unit honors him. His surname is traditionally pronounced to rhyme with 'tool' or 'jewel,' a small phonetic argument that has never quite been settled.
