* Speed is a concept, not a tangible thing. We don't find speed like we find a new element or a new planet.
* Humans have always been aware of movement and the relative rates of movement. Even ancient people understood that some things move faster than others.
* The idea of speed as a measurable quantity evolved over time. Early civilizations likely had informal ways of comparing speeds (like comparing the speed of a runner to a horse).
Key milestones in the development of the concept of speed:
* Ancient Greece: Philosophers like Aristotle pondered the nature of motion and change.
* Medieval Era: Scholars developed the beginnings of kinematics (the study of motion), focusing on things like distance and time.
* 14th Century: The concept of instantaneous velocity (speed at a specific moment) was explored by mathematicians like Thomas Bradwardine.
* 17th Century: Galileo Galilei made major contributions to the understanding of speed and acceleration through his experiments with falling objects and inclined planes.
* 18th & 19th Centuries: Newton's laws of motion formalized the relationship between force, mass, and acceleration, further defining our understanding of speed.
In summary: While we can't say exactly when "speed" was "discovered," we can trace its development through history as a concept that evolved from simple observations to precise mathematical definitions.
