2.2.2 Alloys

... This is pretty much an empirical law, it does not pay to justify it theoretically. Again, it is not possible to produce an alloy with a resistivity smaller than one of its components. If you have intermetallic compounds in your phase diagram, use Nordheim's rule with the intermetallic phases as XA a ...

... To fully reconstruct the path, we need an additional set of wires at right angles to the first set. The two sets of wires together (a grid) can be used to find the position from which the electrons were emitted, i.e. the position of the charged particle on a plane. A second grid of wires parallel to ...

Gibbs paradox

In statistical mechanics, a semi-classical derivation of the entropy that does not take into account the indistinguishability of particles, yields an expression for the entropy which is not extensive (is not proportional to the amount of substance in question). This leads to a paradox known as the Gibbs paradox, after Josiah Willard Gibbs. The paradox allows for the entropy of closed systems to decrease, violating the second law of thermodynamics. A related paradox is the ""mixing paradox"". If one takes the perspective that the definition of entropy must be changed so as to ignore particle permutation, the paradox is averted.
