Sol-Gel derived Ferroelectric Thin Films for Voltage Tunable Applications There are no physicists in the hottest parts of hell, because the existence of a 'hottest part' implies a temperature difference, and any marginally competent physicist would immediately use this to run a heat engine and make some other part of hell comfortably cool. This is obviously impossible. Richard Davisson That theory is worthless. It isn't even wrong! Wolfgang Pauli Science is facts; just as houses are made of stones, so is science made of facts; but a pile of stones is not a house and a collection of facts is not necessarily science. Henri Poincare (1854 - 1912) 109
