Quote by Felix Alba-Juez
It is worth noting that a wrong folkoric definition of an Inertial Frame in the Popular Science literature (even in text books) reads that 'it is a frame in uniform motion'. We know very well by now that the idea of motion requires a frame of reference, so that such a definition of an Inertial Frame has no meaning whatsoever, confusing the reader because it tacitly reaffirms the idea of absolute motion -- when the goal of every didactic exposition of Relativity Theory should be precisely the opposite.
Summary
This quote highlights a misconception about the definition of an Inertial Frame, often found in popular science literature. It stresses that it is incorrect to define an Inertial Frame as a frame in uniform motion, as this definition implies the existence of absolute motion. However, the concept of motion requires a frame of reference, so this definition is inherently flawed and misleading. The author emphasizes the importance of clarifying and dispelling such misconceptions in order to promote a better understanding of Relativity Theory.
