I agree, well worth sharing. For me it bring back memories of a lecturer struggling to work out how to re wind the film when we wanted to see it again , and of the blank faces of a couple of my A level Physics students who could not add fractions even with the aid of calculators . Powers of 10 were just a leap too far. They had the advantage of being able to see it again by re wining the Beatmax version . Ahh true progress .
