The Murray Darling Basin is a vast fertile region in the south-east of New South Wales. One of the world’s longest river systems, it is host to a thriving agricultural region and a fascinating human history. Intensive farming ever since the 1800’s is now taking its toll on the environment. If the region is to continue as an agricultural bowl then the issue of sustainable development needs to be addressed.

Sons et Phenomenes Vibratratoires
La physique de la musique nous emmene dans un voyage derriere la beaute et l’inspiration de la musique afin d’explorer ses principles scientifiques. Nous examinons une large gamme d’instruments, allant du violon classique au ‘didjeridoo’ et au synthetiseur pur illustrer les concepts et les formules des ondes sonores. L’oscilloscope a rayons cathodiques est largement utilise pour demontrer comment les notes musicales complexes sont construites a partir de formes d’ondes plus simples.
