Video of the day: Powers of ten

This video is proof positive that the entertainment sector is more important for human health, happiness and the spread of knowledge than the entire fringe therapy industry. It was spotted and posted to YouTube by a video director who works for a rock band (who I am not going to name because one can only take so many perverts and whackjobs infesting the search terms).

It’s not recent: it was made in the 1970s. However, the maths covered hasn’t changed an iota. Do you have trouble visualising exactly what Avogadro’s number (usually rendered as 1023) really means?
