Newton's apple
Physics origin story
Newton's apple is the legendary fruit whose fall supposedly inspired Isaac Newton's theory of gravity.
The story—likely embellished—has Newton observing an apple drop and wondering why objects fall straight down rather than sideways.
The phrase now represents any ordinary event that triggers a profound scientific insight: That conversation was my Newton's apple moment.
