PROBLEM: He adapted Joseph Blackburn's portrait d'apparat method for his works depicting a fat-looking woman with a blue book in Mrs. James Russell, Katherine Graves, an old elegant lady with a hint of a mustache in Mrs. Thomas Boylston, and a red-coated Samuel Adams. Influenced by John Smibert, his later historical works include The Death of the Earl of Chatham and The Death of Major Peirson. His The Boy with a Squirrel got him noticed, and he also painted a famous portrait of Paul Revere at his silver shop. FTP, name this American artist who depicted a dangerous incident occurring in Havana harbor in his Watson and the Shark.

SOLUTION: Fine Arts

PROBLEM: 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.

SOLUTION: Science

PROBLEM: This writer built upon work by John Grote and William James in distinguishing between "knowledge by acquaintance" and "knowledge by description". He also developed James' idea that the basic building block of everything was neither mind nor matter, his theory of neutral monism. In one of his works, he explained why he did not believe in God and immortality and did not believe Christ was the the best and wisest of men, and he also compared belief in God to belief in a celestial teapot. This thinker developed type theory to resolve a problem with Gottlob Frege's set theory, which he found to allow his paradox of the set of all sets that are not members of themselves. Name this author of Why I Am Not a Christian who worked with Alfred North Whitehead on Principia Mathematica.
