The conservation of energy is not a statement about pure mathematics or logic, it is a statement about the physical world, so it's not surprising that historically its derivation has come from observation and experimentation. Nobody has ever been able to derive the conservation of energy from logic alone, and I very much doubt anybody ever will. In fact nobody has ever been able to derive ANY physical law from mathematics alone, unless you want to say that it's a physical law that 2 rocks plus another 2 rocks is equal to 4 rocks. * *>You're mistaken.* *BULLSHIT!* * > Look it up.
