A ruptured duodenal ulcer caused kidney failure, and he declined to undergo the dialysis that might have prolonged his life for a few months. Feynman's wife Gweneth, sister Joan, and cousin Frances Lewine watched over him during the final days of his life until he died on February 15, 1988.

Mount Sunflower (Wikipedia) Mount Sunflower, although not a true mountain, is the highest natural point in the U.S. state of Kansas. At 4,039 feet (1,231 m), it is 3,300 feet (1,010 m) above the state’s topographic low point, which lies on the opposite side of the state. It is located between the communities of Kanorado and Weskan in Wallace County, less than half a mile (0.8 km) from the state border with Colorado and is near the lowest point in Colorado.

Richard Feynman (Wikipedia) Richard Phillips Feynman (/ˈfaɪnmən/; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin’ichirō Tomonaga.
