If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
No such thing.
For any given problem, once a possible solution is reached, do you expect to be able to check that solution against reality with further observations? If so, you have constructed a theory with experimental implications, and are doing Science. If not, you have derived the truth, falsehood, or invalidity of a particular statement from a core set of axioms, and are doing Math.
