The meter, the second and the traditional base 10 are useful standards to communicate quantitative measurements, for instance of the radius of an explosion over time. However, these subjective units for space, time and numbers themselves obscure the scale-invariant similarity of physical phenomena, like the deep kinship between explosions of all sorts, from tiny laser-induced blasts to supernovae. Nature could not care less about the length of our feet and the number of our fingers. In this seventh episode we show that explosions provide a great example of the inherent indifference of Nature on our arbitrary subjective standards to measure and to count. We show that any explosion not only provides its own objective units, but also its own base for counting. After spending the last episodes freeing ourselves from subjective units, it is now time to do physics beyond base 10.
