INTRO: One of Galileo Galilei’s many contributions to science was his understanding of relative motion – that the physics within a system do not depend on the speed at which the system moves relative to external systems, provided the original system is not accelerating. This idea would go on to form the foundations for Einstein’s Relativity Principle which required that the physics of the system does not depend on the inertial frame chosen to study it. Though subtly different, modern physics often conflates these ideas leading to conflicting resolutions to Galileo’s initial problem. Sebastián Murgueitio Ramírez argues that by distinguishing between an "internal" and "external" version of the principle, we can right this, clarify its original meaning and appreciate just how far ahead of his time Galileo truly was...
