4-10 October is  World Space Week. In this blog, we explore how the human race has viewed space through the ages – from medieval astronomical diagrams to modern cartoons. You can also watch the 1978 launch of space shuttle ‘Enterprise’ at Cape Canaveral and listen to Holst’s ‘Planets’ orchestral suite.

A “frame of reference” is a standard relative to which motion and rest may be measured; any set of points or objects that are at rest relative to one another enables us, in principle, to describe the relative motions of bodies. A frame of reference is therefore a purely kinematical device, for the geometrical description of motion without regard to the masses or forces involved. A dynamical account of motion leads to the idea of an “inertial frame,” or a reference frame relative to which motions have distinguished dynamical properties. For that reason an inertial frame has to be understood as a spatial reference frame together with some means of measuring time, so that uniform motions can be distinguished from accelerated motions.
