Its the difference between knowing that a process can be done by doing a sequence of actions and knowing how that process works.
For example, we know how fire can be made but once we start one apart from fanning it and putting it out, we can't really do much to manipulate the actual flame outside of specific conditions. To gain the knowledge to do so would be to bring in many great advances, I'm sure of that.
Again, it's not about the process. It's about the knowledge behind that process, because applying that knowledge to other things we can achieve so much more.
