Article: The first practical ICs were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon, whereas Kilby's chip was made of germanium.

Question: Noyce's IC was made up of what material?
Ans: silicon

Article: Other important sectors include medical research and technology, non-profit institutions, and universities. Manufacturing accounts for a significant but declining share of employment, although the city's garment industry is showing a resurgence in Brooklyn. Food processing is a US$5 billion industry that employs more than 19,000 residents.

Question: What is the annual revenue of the food processing industry?
Ans: US$5 billion

Article: In principle, the Planck constant could be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, and this is how its value was first calculated in the early twentieth century. In practice, these are no longer the most accurate methods. The CODATA value quoted here is based on three watt-balance measurements of KJ2RK and one inter-laboratory determination of the molar volume of silicon, but is mostly determined by a 2007 watt-balance measurement made at the U.S. National Institute of Standards and Technology (NIST). Five other measurements by three different methods were initially considered, but not included in the final refinement as they were too imprecise to affect the result.

Question: One other measure involved the molar volume of what element?
Ans: silicon

Article: In the 18th century, the Moroccan Sultan Moulay Ismail "the Bloodthirsty" (16721727) raised a corps of 150,000 black slaves, called his Black Guard, who coerced the country into submission.

Question: What did the Black Guard do?
Ans:
coerced the country into submission.
