Actually, Physics is just an extension of process of observation.
Theory - observation - more theory about the observation - observation and proof — more theory — more observation... until we are way out on a limb in the classical sense. The scientific process.
No, it really isn't.
Saying The First Law of Thermodynamics "proves" that matter can't be created nor destroyed is wrong. The First Law doesn't "prove" anything, and it doesn't explain anything. It's an observation. That's ALL.
Actually, Physics is just an extension of process of observation.
This statement is objectively false. Physics is a branch of science which uses some observations in a specific way as part of its discipline. There is much more to it than that, and the act of systematically organizing, understanding, and predicting are far more important elements of the discipline than simple observation. These are what differentiates physics from sitting on your couch watching TV.
If I accepted physics as just an "extension of observation" [and I most certainly won't] I would have to say that Mayan astronomers were "physicists." No. They were not. They were just people taking some basic measurements and using them to decide when to plant or worship gods. That's not physics.
The science that attempts to explain it is totally bizarre and strange and completely unexpected.
Says who? Some jag-off who writes crap like The Dao of Physics? "Totally bizarre and strange" and "completely unexpected" are subjective, editorial comments that mean nothing. They may comport with your ideas, but so what? What we know about physics is determined by careful observation, serious logic and rigorous mathematics. People who attempt to mystify it are charlatans and poseurs.
