Context and question: The theoretical difficulties arise from the fact that all of the methods except the X-ray crystal density method rely on the theoretical basis of the Josephson effect and the quantum Hall effect. If these theories are slightly inaccurate though there is no evidence at present to suggest they are the methods would not give accurate values for the Planck constant. More importantly, the values of the Planck constant obtained in this way cannot be used as tests of the theories without falling into a circular argument. Fortunately, there are other statistical ways of testing the theories, and the theories have yet to be refuted.
Other than the X-ray crystal density method, other methods rely on what two effects?
Answer: the Josephson effect and the quantum Hall effect
Context and question: The most serious objection to regarding the Demoiselles as the origin of Cubism, with its evident influence of primitive art, is that "such deductions are unhistorical", wrote the art historian Daniel Robbins. This familiar explanation "fails to give adequate consideration to the complexities of a flourishing art that existed just before and during the period when Picasso's new painting developed." Between 1905 and 1908, a conscious search for a new style caused rapid changes in art across France, Germany, Holland, Italy, and Russia. The Impressionists had used a double point of view, and both Les Nabis and the Symbolists (who also admired Cezanne) flattened the picture plane, reducing their subjects to simple geometric forms. Neo-Impressionist structure and subject matter, most notably to be seen in the works of Georges Seurat (e.g., Parade de Cirque, Le Chahut and Le Cirque), was another important influence. There were also parallels in the development of literature and social thought.
Which technique did the Impressionists use to make their subjects simple forms?
Answer: double point of view
Context and question: In April 1979, young students protested against Bokassa's decree that all school attendees would need to buy uniforms from a company owned by one of his wives. The government violently suppressed the protests, killing 100 children and teenagers. Bokassa himself may have been personally involved in some of the killings. In September 1979, France overthrew Bokassa and "restored" Dacko to power (subsequently restoring the name of the country to the Central African Republic). Dacko, in turn, was again overthrown in a coup by General Andre Kolingba on 1 September 1981.
Who did General Andre protest against in April 1979?
