We analyze the difference between classical mechanics and quantum mechanics. We come to the conclusion that this difference can be found in the nature of the observables that are considered for the physical system under consideration. Classical mechanics can only describe a certain kind of what we called ''classical observable.''

E. B. Makinson. The methods used to measure separately the electronic and lattice heat conductivities ? e and ? g in a metal are reviewed, and it is pointed out that care is necessary in interpreting the results in view of the underlying assumptions.
