In 1938 Otto Hahn and Fritz Strassmann discovered nuclear fission with radiochemical methods, and in 1939 Lise Meitner and Otto Robert Frisch wrote the first theoretical interpretation of the fission process, which was later improved by Niels Bohr and John A. Wheeler. Further developments took place during World War II, which led to the practical application of radar and the development and use of the atomic bomb. Though the process had begun with the invention of the cyclotron by Ernest O. Lawrence in the 1930s, physics in the postwar period entered into a phase of what historians have called "Big Science", requiring massive machines, budgets, and laboratories in order to test their theories and move into new frontiers. The primary patron of physics became state governments, who recognized that the support of "basic" research could often lead to technologies useful to both military and industrial applications. Currently, general relativity and quantum mechanics are inconsistent with each other, and efforts are underway to unify the two.
Who discovered nuclear fission?
A: Otto Hahn and Fritz Strassmann

Rome's preoccupation with its war with Carthage provided an opportunity for Philip V of the kingdom of Macedonia, located in the north of the Greek peninsula, to attempt to extend his power westward. Philip sent ambassadors to Hannibal's camp in Italy, to negotiate an alliance as common enemies of Rome. However, Rome discovered the agreement when Philip's emissaries were captured by a Roman fleet. The First Macedonian War saw the Romans involved directly in only limited land operations, but they ultimately achieved their objective of pre-occupying Philip and preventing him from aiding Hannibal.
What peninsula was the kingdom of Macedonia able to be found in?
A: Greek peninsula

The Region of Île de France, including Paris and its surrounding communities, is governed by the Regional Council, which has its headquarters in the 7th arrondissement of Paris. It is composed of 209 members representing the different communes within the region. On December 15, 2015, a list of candidates of the Union of the Right, a coalition of centrist and right-wing parties, led by Valérie Pécresse, narrowly won the regional election, defeating a coalition of Socialists and ecologists. The Socialists had governed the region for seventeen years. In 2016, the new regional council will have 121 members from the Union of the Right, 66 from the Union of the Left and 22 from the extreme right National Front.
How many council members will they have in 2016 from the union of the Right?
A: 121

Copper's greater conductivity versus other metals enhances the electrical energy efficiency of motors. This is important because motors and motor-driven systems account for 43%-46% of all global electricity consumption and 69% of all electricity used by industry. Increasing the mass and cross section of copper in a coil increases the electrical energy efficiency of the motor. Copper motor rotors, a new technology designed for motor applications where energy savings are prime design objectives, are enabling general-purpose induction motors to meet and exceed National Electrical Manufacturers Association (NEMA) premium efficiency standards.
What does the acronym NEMA stand for?
A:
National Electrical Manufacturers Association
