Sometimes invention of new things are through mistakes. That maurice ward discovered an object that was unable to burn was due to his interest over the object that resist fire. But most times in our country Nigeria you hardly see a hair dresser who will put much attention to know the reason why the object was able to resist fire. This may be because of inferiority complex over what people will say. That is why,it is always good to build more courage when doing things than bringing yourself down. Thanks a lot,at least i have learnt something from this. Nice one
