Question: Thomas Edison began serious research into developing a practical incandescent lamp in 1878. Edison filed his first patent application for "Improvement In Electric Lights" on 14 October 1878. After many experiments, first with carbon in the early 1880s and then with platinum and other metals, in the end Edison returned to a carbon filament. The first successful test was on 22 October 1879, and lasted 13.5 hours. Edison continued to improve this design and by 4 November 1879, filed for a US patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires." Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," Edison and his team later discovered that a carbonized bamboo filament could last more than 1200 hours. In 1880, the Oregon Railroad and Navigation Company steamer, Columbia, became the first application for Edison's incandescent electric lamps (it was also the first ship to execute use of a dynamo).
Try to answer this question if possible: How long did Edison's light burn during his first successful test in 1879?
Answer: 13.5 hours
Question: Isabelle Stengers wrote that "Whiteheadians are recruited among both philosophers and theologians, and the palette has been enriched by practitioners from the most diverse horizons, from ecology to feminism, practices that unite political struggle and spirituality with the sciences of education." Indeed, in recent decades attention to Whitehead's work has become more widespread, with interest extending to intellectuals in Europe and China, and coming from such diverse fields as ecology, physics, biology, education, economics, and psychology. One of the first theologians to attempt to interact with Whitehead's thought was the future Archbishop of Canterbury, William Temple. In Temple's Gifford Lectures of 1932-1934 (subsequently published as "Nature, Man and God"), Whitehead is one of a number of philosophers of the emergent evolution approach Temple interacts with. However, it was not until the 1970s and 1980s that Whitehead's thought drew much attention outside of a small group of philosophers and theologians, primarily Americans, and even today he is not considered especially influential outside of relatively specialized circles.

Question: India's cotton-processing sector gradually declined during British expansion in India and the establishment of colonial rule during the late 18th and early 19th centuries. This was largely due to aggressive colonialist mercantile policies of the British East India Company, which made cotton processing and manufacturing workshops in India uncompetitive. Indian markets were increasingly forced to supply only raw cotton and, by British-imposed law, to purchase manufactured textiles from Britain.[citation needed]

Question: Yale has had many financial supporters, but some stand out by the magnitude or timeliness of their contributions. Among those who have made large donations commemorated at the university are: Elihu Yale; Jeremiah Dummer; the Harkness family (Edward, Anna, and William); the Beinecke family (Edwin, Frederick, and Walter); John William Sterling; Payne Whitney; Joseph E. Sheffield, Paul Mellon, Charles B. G. Murphy and William K. Lanman. The Yale Class of 1954, led by Richard Gilder, donated $70 million in commemoration of their 50th reunion. Charles B. Johnson, a 1954 graduate of Yale College, pledged a $250 million gift in 2013 to support of the construction of two new residential colleges.
Try to answer this question if possible: How much did the 1954 class donate for their 40th reunion?
