“The oxide superconductors, particularly those recently discovered that are based on La2CuO4, have a set of peculiarities that suggest a common, unique mechanism: they tend in every case to occur near a metal-insulator transition into an odd-electron insulator with peculiar magnetic properties. This insulating phase is proposed to be the long-sought "resonating-valence-bond" state or "quantum spin liquid" hypothesized in 1973. This insulating magnetic phase is favored by low spin, low dimensionality, and magnetic frustration. The preexisting magnetic singlet pairs of the insulating state become charged superconducting pairs when the insulator is doped sufficiently strongly.”

“In cold climates it will cost only half as much to heat a well insulated building as it will cost to heat a poorly insulated one. … the annual fuel saving will amortize in two years the addition cost expense of the insulation!”

“Engineers did not discover insulation: they copied it from these old soldiers of the prairie war.”

“Any system that insulates itself from diversity in the environment tends to atrophy and lose its complexity and distinctive nature”

“Bedroom insulation is unnecessary and restrictive of optimum summer sleeping comfort.”

“The centrally planned economics used to consider themselves well insulated against the economic ills of the rest of the world. This is no longer the case.”

“Anna accumulated things as a way of insulating herself against her own thoughts.”

“… don't read anything except what destroys the insulation between yourself and your experience…”

“We must talk about poverty, because people insulated by their own comfort lose sight of it.”

“Fame without the money to insulate you from it is one of the most wretched human conditions possible.”
