From an engineering point of view, a scientific theory does not have to be true. It just has to be useful.
Hello John,
a bold statement ;-)
But it is true that for an engineer the priority is that it works, knowing how it works is a bonus, while for a scientist the last is the most important.
Being a (lonely) engineer working with scientist I sometimes try to explain the difference between a scientist and an engineer this way:
When a scientist builds a bridge it will collapse, but the scientist can perfectly explain why it collapsed. When an engineer builds a bridge it will not collapse, but the engineer will not have a clue why it does not collapse.
