Ex Input:
An anharmonic oscillator exploiting this effect as a microelectromechanical system component was proposed by Serry, Walliser, and Maclay. Julian Schwinger has postulated that sonoluminescence arises due to this effect, and this effect requires that bag radius and mass are independent under a combination of the Skyrmion and MIT models, the chiral bag model of the nucleon. One setup for measuring it attached a polystyrene sphere to an atomic force microscope, and Lamoreaux used a torsional pendulum to achieve the first precise measurements of this effect. This force may produce pressures as large as an atmosphere at a separation of ten nanometers. For 10 points, name this effect arising from zero-point energy, described by the attraction or repulsion due to virtual photons between two close uncharged metallic sheets in a vacuum.

Ex Input:
One character in this novel receives news of her brother's death from her father while he uses a lathe. This novel's protagonist develops a friendship with Platon Karataev, a peasant he meets in a prisoner of war camp. Another character, Nikolai, is led to financial ruin after(*) losing 40,000 roubles to Dolokov. Andrei Bolkonski is wounded in battle following the end of his engagement to Natasha Rostova, who falls in love with the novel's protagonist. For 10 points, name this gargantuan Leo Tolstoy novel about Pierre Bezukhov set during the Napoleonic Wars.

Ex Output:
Literature


Ex Input:
Bruce Cork discovered the antiparticle partner for this particle in 1956, 24 years after James Chadwick discovered this particle itself in 1932. A free version of this particle has a mean lifetime of just under 15 minutes. A flavor change via a W boson from a down quark to an up quark causes this particle to decay, during which it produces an electron antineutrino, an electron, and another type of nucleon. The number of this particle in an atom determines the isotope of an element. For 10 points, identify this subatomic particle, slightly heavier than the proton, that has zero charge.
