That's completely wrong (sorry, I know, I was going to stop). Newton  
laws are definitely not obsolete - the only thing that happened to  
them is that bounds of their applicability area were refined.  
Moreover, there is no scientific theory that was obsoleted by  
something new - AFAIK even flogiston theory is still here.
