I don't know if you've ever looked into what goes on physically in the combustion chamber or even just the turbopumps? We are far away from having the physics identified, let alone the math figured out. E.g., combustion instability is one of those phenomena where an engine explodes, but we don't understand what's going on (sure, sometimes it can be mitigated). Sounds pretty sciency to me.
