ConservationOfEnergy

Good explanation http://www.entropylaw.com/entropyenergy.html

Complete with this great diagram of Joule's experiment to demonstrate conservation of energy

Something that strikes me as quite interesting here. Given that it's impossible to produce a perfectly efficient process for converting energy from one form to another. Conservation of energy is impossible to observe or demonstrate.

So what's the PhilosophyOfScience role of experimental evidence here, given CoE can't be observed?

• If we don't have confirming observations of the theory, this theory could never have arrived by induction from observation

• If we can't have empirically observe it, it's impossible to make falsifying observations, hence falsificationism is out (or CoE isn't a scientific hypothesis)
