Any nagging intruder who stops by with unsought advice will see them immediately. If an experiment works, you must be using the wrong equipment. An experiment may be considered successful if no more than half the data must be discarded to agree with the theory. No experiment is ever a complete failure. It can serve as a bad example.
Raw data is like raw sewage, it requires some processing before it can be spread around.
The opposite is true of theories. No experiment is reproducible 2. Anything can be made to work if you fiddle with it long enough. I believe there is a scientific method, or at least a method that serves me well. There will always be some kind of graph paper on which they fall in a straight line.
