[EX Q]: Passage: Hilda Rix Nicholas (née Rix, later Wright, 1 September 1884 – 3 August 1961) was an Australian artist. Hilda Rix was born in the Victorian city of Ballarat. Her father was an education administrator and poet, her mother was a musician and artist. She studied under a leading member of the Heidelberg School, Frederick McCubbin, at the National Gallery of Victoria Art School from 1902 to 1905 and was an early member of the Melbourne Society of Women Painters and Sculptors. Following the death of her father in 1907, Hilda Rix, her only sibling Elsie and her mother travelled to Europe where she undertook further study in London and then in Paris. Her teachers during the period included John Hassall, Richard Emil Miller and Théophile Steinlen.
After travelling to Tangiers in 1912, Rix held several successful exhibitions of her work, with one drawing, Grande marche, Tanger, purchased by the French government. She was one of the first Australians to paint post-impressionist landscapes, was made a member of the Société des Peintres Orientalistes Français, and had works hung in the Paris Salon first in 1911 and again in 1913. The family evacuated from France to England after the outbreak of World War I. A period of personal tragedy followed, as Rix's sister died in 1914, then her mother in 1915. In 1916 she met and married George Matson Nicholas, only to be widowed the next month when he was killed on the Western Front.
Returning to Australia in 1918, Rix Nicholas once more took up professional painting, and held an exhibition of over a hundred works at Melbourne's Guild Hall. Many sold, including In Picardy, purchased by the National Gallery of Victoria. Following a period painting in rural locations in the early 1920s, Rix Nicholas returned to Europe. A 1925 exhibition in Paris led to the sale of her work In Australia to the Musée du Luxembourg, followed by an extensive tour of her paintings around regional British art galleries. There followed representation in other exhibitions, including at the International Society of Sculptors, Painters and Gravers, and the Royal Academy of Arts, both in London. Following the inclusion of several works in the 1926 Société Nationale des Beaux-Arts Spring exhibition in Paris she was made an Associate of that organisation.

[EX Q]: Passage: Bristol has two major institutions of higher education: the University of Bristol, a redbrick chartered in 1909, and the University of the West of England, opened as Bristol Polytechnic in 1969, which became a university in 1992. The University of Law also has a campus in the city. Bristol has two further education institutions (City of Bristol College and South Gloucestershire and Stroud College) and two theological colleges: Trinity College, and Bristol Baptist College. The city has 129 infant, junior and primary schools,17 secondary schools, and three learning centres. After a section of north London, Bristol has England's second-highest number of independent school places. Independent schools in the city include Clifton College, Clifton High School, Badminton School, Bristol Grammar School, Queen Elizabeth's Hospital (the only all-boys school) and the Redmaids' School (founded in 1634 by John Whitson, which claims to be England's oldest girls' school).
In 2005 Chancellor of the Exchequer Gordon Brown named Bristol one of six English "science cities",
and a £300 million science park was planned at Emersons Green. Research is conducted at the two universities, the Bristol Royal Infirmary and Southmead Hospital, and science outreach is practiced at We The Curious, the Bristol Zoo, the Bristol Festival of Nature and the Create Centre.The city has produced a number of scientists, including 19th-century chemist Humphry Davy (who worked in Hotwells). Physicist Paul Dirac (from Bishopston) received the 1933 Nobel Prize for his contributions to quantum mechanics. Cecil Frank Powell was the Melvill Wills Professor of Physics at the University of Bristol when he received the 1950 Nobel Prize for, among other discoveries, his photographic method of studying nuclear processes. Colin Pillinger was the planetary scientist behind the Beagle 2 project, and neuropsychologist Richard Gregory founded the Exploratory (a hands-on science centre which was the predecessor of At-Bristol/We The Curious).Initiatives such as the Flying Start Challenge encourage an interest in science and engineering in Bristol secondary-school pupils; links with aerospace companies impart technical information and advance student understanding of design.
The Bloodhound SSC project to break the land speed record is based at the Bloodhound Technology Centre on the city's harbourside. 
Question: What is the first name of the person whose photographic method of studying nuclear processes won him an award?
