Q: Context_1 : Arthur Bruce McDonald, {'1': ", '2': ", '3': ", '4': "} (born August 29, 1943) is a Canadian astrophysicist. McDonald is the director of the Sudbury Neutrino Observatory Institute and holds the Gordon and Patricia Gray Chair in Particle Astrophysics at Queen's University in Kingston, Ontario. He was awarded the 2015 Nobel Prize in Physics jointly with Japanese physicist Takaaki Kajita. Context_2 : Brian David Josephson, {'1': ", '2': ", '3': ", '4': "} (born 4 January 1940), is a Welsh theoretical physicist and professor emeritus of physics at the University of Cambridge. Best known for his pioneering work on superconductivity and quantum tunnelling, he was awarded the Nobel Prize in Physics in 1973 for his prediction of the Josephson effect, made in 1962 when he was a 22-year-old PhD student at Cambridge University. Josephson is the only Welshman to have won a Nobel Prize in Physics. He shared the prize with physicists Leo Esaki and Ivar Giaever, who jointly received half the award for their own work on quantum tunnelling. Context_3 : Douglas Dean Osheroff (born August 1, 1945) is a physicist known for his work in experimental condensed matter physics, in particular for his co-discovery of superfluidity in Helium-3. For his contributions he shared the 1996 Nobel Prize in Physics along with David Lee and Robert C. Richardson. Context_4 : Takaaki Kajita ( , Kajita Takaaki ) is a Japanese physicist, known for neutrino experiments at the Kamiokande and its successor, Super-Kamiokande. In 2015, he was awarded the Nobel Prize in Physics jointly with Canadian physicist Arthur B. McDonald. Context_5 : Dr. Eric 'Davis' Earle (died 24 December 2016) was a Canadian nuclear physicist. A Rhodes Scholar, he worked at Chalk River and helped organize Sudbury Neutrino Observatory as part of the project team whose director, Arthur B. McDonald, won the 2015 Nobel Prize in Physics. Context_6 : Since 1901, the Nobel Prize in Literature (Swedish: "Nobelpriset i litteratur" ) has been awarded annually to an author from any country who has, in the words of the will of Alfred Nobel, produced "in the field of literature the most outstanding work in an ideal direction" (original Swedish: "den som inom litteraturen har producerat det mest framstaende verket i en idealisk riktning"). Though individual works are sometimes cited as being particularly noteworthy, here "work" refers to an author's work as a whole. The Swedish Academy decides who, if anyone, will receive the prize in any given year. The academy announces the name of the chosen laureate in early October. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895; the others are the Nobel Prize in Chemistry, Nobel Prize in Physics, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine. Context_7 : Aage Niels Bohr (] ; 19 June 1922 8 September 2009) was a Danish nuclear physicist who shared the Nobel Prize in Physics in 1975 with Ben Mottelson and James Rainwater "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection". Starting from Rainwater's concept of an irregular-shaped liquid drop model of the nucleus, Bohr and Mottelson developed a detailed theory that was in close agreement with experiments. Since his father, Niels Bohr, had won the prize in 1922, he and his father were one of the six pairs of fathers and sons who have both won the Nobel Prize and one of the four pairs who have both won the Nobel Prize in Physics. Context_8 : Reona Esaki ( "Esaki Reona", born March 12, 1925), also known as Leo Esaki, is a Japanese physicist who shared the Nobel Prize in Physics in 1973 with Ivar Giaever and Brian David Josephson for his discovery of the phenomenon of electron tunneling. He is known for his invention of the Esaki diode, which exploited that phenomenon. This research was done when he was with Tokyo Tsushin Kogyo (now known as Sony). He has also contributed in being a pioneer of the semiconductor superlattices. Context_9 : In particle physics, a massless particle is an elementary particle whose invariant mass is zero. The two known massless particles are both gauge bosons: the photon (carrier of electromagnetism) and the gluon (carrier of the strong force). However, gluons are never observed as free particles, since they are confined within hadrons. Neutrinos were originally thought to be massless. However, because neutrinos change flavor as they travel, at least two of the types of neutrinos must have mass. The discovery of this phenomenon, known as neutrino oscillation, led to Canadian scientist Arthur B. McDonald and Japanese scientist Takaaki Kajita sharing the 2015 Nobel prize in physics. Context_10 : Prof Albert Abraham Michelson (surname pronunciation anglicized as "Michael-son") FFRS HFRSE LLD (December 19, 1852 May 9, 1931) was an American physicist known for his work on measuring the speed of light and especially for the MichelsonMorley experiment. In 1907 he received the Nobel Prize in Physics, becoming the first American to win the Nobel Prize in a science. fact_1 : He was awarded the 2015 Nobel Prize in Physics jointly with Japanese physicist Takaaki Kajita. fact_2 : Takaaki Kajita ( , Kajita Takaaki ) is a Japanese physicist, known for neutrino experiments at the Kamiokande and its successor, Super-Kamiokande. Question: Arthur B. McDonald shared the Nobel Prize in Physics for 2015 with the Japanese physicist known for what type of work?

A: neutrino experiments
