HOWEVER, IT MOVES
What would Galileo think if he got on the space station? What would Newton face be if he saw in GeoGebra a function as a moving point? What would Leibnitz say if he had a symbolic calculator in his hands? What would Louis Daguerre or the Lumière brothers do with a Smartphone? What music would Bach do if he had a synthesizer? What about us, maths teachers?
