In scientific Luganda, a scientific law is called etteeka lya sayansi or ennono ya sayansi. To apply a scientific law is what we call okunonooza and the entire process is called “ekinonoozo” which is “engineering”. The specialist who applies the laws of science to build systems or machines is called “omunonooza”, an engineer. Unlike ekigereeso kya sayansi, ennono ya sayansi is confirmed beyond reasonable doubt that it is valid in all situation and everywhere.
