Page viii - Pour comprendre la nécessité de modifier profondément les méthodes d'enseignement de la chimie, il suffit de comparer un cours de chimie et un cours de physique. Ces deux sciences ont un objet analogue; elles étudient toutes deux les phénomènes donnant lieu à des transformations de l'énergie, c'est-à-dire puissance mécanique, calorifique, électrique ou chimique. Dans l'enseignement de la physique, on ne parle que des lois des phénomènes naturels...
