Question: Ève Curie is the younger daughter of the physicist and pioneer in what fields?
Context: Ève Denise Curie Labouisse (December 6, 1904 – October 22, 2007) was a French and American writer, journalist and pianist.  Ève Curie was the younger daughter of Marie Skłodowska-Curie and Pierre Curie.  Her sister was Irène Joliot-Curie and her brother-in-law Frédéric Joliot-Curie.  Ève was the only member of her family who did not choose a career as a scientist and did not win a Nobel Prize, although her husband Henry Richardson Labouisse, Jr. did collect the Nobel Peace Prize in 1965 on behalf of UNICEF.  She worked as a journalist and authored her mother's biography "Madame Curie" and a book of war reportage, "Journey Among Warriors".  From the 1960s she committed herself to work for UNICEF, providing help to children and mothers in developing countries. Journey Among Warriors is a book of war reportage by the French-American journalist and writer Ève Curie, first published in 1943, in which the author described her experiences during her trip to Africa, the Near East, Soviet Union, China, Burma and India, where she traveled from November 1941 to April 1942. Mathilde Carmen Hertz (14 January 1891 – 20 November 1975) was a biologist, and was one of the first influential women scientists in the field of biology and a pioneer in the field of comparative psychology.  Working in Germany, her career started to unravel in 1933 due to her Jewish ancestry.  She was the younger daughter of the famous physicist Heinrich Rudolf Hertz. The Radium Woman: A youth edition of the life of Madame Curie is a biography of the scientist Marie Curie adapted for children by Eleanor Doorly from the 1937 biography by Ève Curie.  It was published by Heinemann in 1939 with woodcuts by Robert Gibbings as chapter headings. Paul-Jacques Curie (29 October 1855 – 19 February 1941) was a French physicist and professor of mineralogy at the University of Montpellier.  Along with his younger brother, Pierre Curie, he studied pyroelectricity in the 1880s, leading to their discovery of piezoelectricity and some of the mechanisms involved. Madame Curie is a 1943 biographical film made by Metro-Goldwyn-Mayer.  The film was directed by Mervyn LeRoy and produced by Sidney Franklin from a screenplay by Paul Osborn, Paul H. Rameau, and Aldous Huxley (uncredited), adapted from the biography by Ève Curie.  It stars Greer Garson, Walter Pidgeon, with supporting performances by Robert Walker, Henry Travers, and Albert Bassermann. Pierre Curie ( ; ] ; 15 May 1859 – 19 April 1906) was a French physicist, a pioneer in crystallography, magnetism, piezoelectricity and radioactivity.  In 1903 he received the Nobel Prize in Physics with his wife, Marie Skłodowska-Curie, and Henri Becquerel, "in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel". Rue Madame Curie is a street in Beirut, Lebanon.  The street, which is named in honor of Marie Curie, the Polish–French physicist–chemist, begins at Rue Badr Demachkieh in the Raouché neighborhood of the Ras Beirut district, running west–east through the Qoreitem-Snoubra neighborhood then, intersecting Rue Alfred Nobel and Rue Dunant before turning into Rue Marie Edde.  The street runs south of the Lebanese American University campus.  Le Bristol hotel is located on the street.  In 2008, the average residential apartment price on Rue Madame Curie was US$2,500/m. The Musée Curie (Curie Museum) is a historical museum focusing on radiological research.  It is located in the 5th arrondissement at 1, rue Pierre et Marie Curie, Paris, France, and open Wednesday to Saturday, from 1pm to 5pm; admission is free.  The museum was renovated in 2012, thanks to a donation from Ève Curie. The Ewa Reactor was Poland's first research nuclear reactor.  Its name was derived from the first letters of the Polish words: Eksperymentalny" (Experimental), Wodny" (Water), and "Atomowy" (Atomic) as a reference to Ève Curie.
Answer: crystallography, magnetism, piezoelectricity and radioactivity
