Question: What field did the creator of the Plum pudding atomic model win a Nobel prize?

Context paragraphs:
Oxford Sandy and Black: The Oxford Sandy and Black is a breed of domestic pig originating in Oxfordshire.  Named for its colour, which is a base of sandy brown with black patches, the breed is also sometimes called the "Plum Pudding" or "Oxford Forest pig."  Related to the old Berkshire and Tamworth breeds, it is one of the oldest pigs native to Britain.

Biuku Gasa and Eroni Kumana: Biuku Gasa (27 July 1923 – 23 November 2005) and Eroni Kumana (?  – 2 August 2014) were Solomon Islanders of Melanesian descent, who found John F. Kennedy and his surviving "PT-109" crew following the boat's collision with the Japanese destroyer "Amagiri" near Plum Pudding Island on 1 August 1943.  They were from the Western Province of the Solomon Islands.

Rutherford model: The Rutherford model is a model of the atom devised by Ernest Rutherford.  Rutherford directed the famous Geiger–Marsden experiment in 1909 which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect.  Rutherford's new model for the atom, based on the experimental results, contained the new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the atomic mass of the atom.  This region would be known as the "nucleus" of the atom.

Nobel Prize in Literature: 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 framstående 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.

Christmas pudding: Christmas pudding is a type of pudding traditionally served as part of the Christmas dinner in the UK, Ireland and in other countries where it has been brought by British emigrants.  It has its origins in medieval England, and is sometimes known as plum pudding or just "pud", though this can also refer to other kinds of boiled pudding involving dried fruit.  Despite the name "plum pudding," the pudding contains no actual plums due to the pre-Victorian use of the word "plums" as a term for raisins.  The pudding is composed of many dried fruits held together by egg and suet, sometimes moistened by treacle or molasses and flavoured with cinnamon, nutmeg, cloves, ginger, and other spices.  The pudding is usually aged for a month or more, or even a year; the high alcohol content of the pudding prevents it from spoiling during this time.

Thomson problem: The objective of the Thomson problem is to determine the minimum electrostatic potential energy configuration of "N" electrons constrained to the surface of a unit sphere that repel each other with a force given by Coulomb's law.  The physicist J. J. Thomson posed the problem in 1904 after proposing an atomic model, later called the plum pudding model, based on his knowledge of the existence of negatively charged electrons within neutrally-charged atoms.

Plum pudding model: The plum pudding model is one of several scientific models of the atom.  First proposed by J. J. Thomson in 1904 soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model represented an attempt to consolidate the known properties of atoms at the time: 1) electrons are negatively-charged particles and 2) atoms are neutrally-charged.

Aage Bohr: 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.

J. J. Thomson: Sir Joseph John Thomson {'1': ", '2': ", '3': ", '4': "} ( ; 18 December 1856 – 30 August 1940) was an English physicist and Nobel laureate in physics, credited with the discovery and identification of the electron; and with the discovery of the first subatomic particle.

Ada Yonath: Ada E. Yonath (Hebrew: עדה יונת‎ ‎ , ] ) (born 22 June 1939) is an Israeli crystallographer best known for her pioneering work on the structure of the ribosome.  She is the current director of the Helen and Milton A. Kimmelman Center for Biomolecular Structure and Assembly of the Weizmann Institute of Science.  In 2009, she received the Nobel Prize in Chemistry along with Venkatraman Ramakrishnan and Thomas A. Steitz for her studies on the structure and function of the ribosome, becoming the first Israeli woman to win the Nobel Prize out of ten Israeli Nobel laureates, the first woman from the Middle East to win a Nobel prize in the sciences, and the first woman in 45 years to win the Nobel Prize for Chemistry.  However, she said herself that there was nothing special about a woman winning the Prize.
