At the start of January we wanted to do something on our Facebook page to raise awareness about all the problems Australia has been through in the last period. We were shocked at the situation there. For 2 weeks we researched and wrote more about Australian mathematicians and their work. In addition, each post has a link where you can donate for different charities and organizations. Things have changed a little bit since 4th of January when we started this project, but there is still a lot of work to be done. Also, the weather hasn’t been incredibly favourable neither. In this post we want to put together all the information we have discovered in those 2 weeks, including the mathematicians and where you can still donate to help.

She was also part of the team which developed a poverty line as part of the Henderson Inquiry into poverty in Australia and helped to introduce the double randomisation method of ordering candidates used in Australian elections. In June 2019, Harcourt was made an officer of the Order of Australia in recognition of her “distinguished service to mathematics and computer science through pioneering research and development of integer linear programming”.

**Mathematician #7: Geordie Williamson**

**Mathematicians #8: Szekeres family**

Donate #8: Currumbin Wildlife Hospital

George Szekeres (29 May 1911 – 28 August 2005) and Esther Szekeres (20 February 1910 – 28 August 2005) were Hungarian–Australian mathematicians.

The so-called Happy Ending problem is an example of how mathematics pervaded George’s life. During 1933, George and several other students met frequently in Budapest to discuss mathematics. At one of these meetings, Esther Klein proposed the following problem:

“Given five points in the plane in general position, prove that four of them form a convex quadrilateral.”

After allowing George, Paul Erdős, and the other students to scratch their heads for some time, Esther explained her proof. Subsequently, George and Paul wrote a paper (1935) that generalises this result; it is regarded as one of the foundational works in the field of combinatorial geometry. Erdős dubbed the original problem the “Happy Ending” problem because it resulted in George and Esther’s marriage in 1937.

**Mathematician #9: Alfred van der Poorten**

Donate #9: NSW Rural Fire Service

Alfred Jacobus van der Poorten (16 May 1942 – 9 October 2010) was a Dutch-Australian number theorist, for many years on the mathematics faculties of the University of New South Wales and Macquarie University. He was the author of approximately 180 publications in number theory, on subjects that included Baker’s theorem, continued fractions, elliptic curves, regular languages, the integer sequences derived from recurrence relations, and transcendental numbers. Some of his significant results include the 1988 solution of Pisot’s conjecture on the rationality of Hadamard quotients of rational functions, his 1992 work with Bernard Dwork on the Eisenstein constant, his work with Enrico Bombieri on Diophantine approximation of algebraic numbers, and his 1999 paper with Kenneth Stuart Williams on the Chowla–Selberg formula.

**Mathematician #10: Peter Jephson Cameron**

Donate #10: GIVIT, a national not-for-profit connecting those who have with those who need, in a private and safe way.

Peter Jephson Cameron FRSE (born 23 January 1947) is an Australian mathematician who works in group theory, combinatorics, coding theory, and model theory. He is currently half-time Professor of Mathematics at the University of St Andrews, and Emeritus Professor at Queen Mary University of London. Cameron specialises in algebra and combinatorics; he has written books about combinatorics, algebra, permutation groups, and logic, and has produced over 250 academic papers. He posed the Cameron–Erdős conjecture with Paul Erdős.

**Mathematician #11: Anne Penfold Street**

Donate #11: The World Wildlife Fund

Anne Penfold Street (1932–2016) was one of Australia’s leading mathematicians, specialising in combinatorics. She was the third woman to become a mathematics professor in Australia, following Hanna Neumann and Cheryl Praeger. She was the author of several textbooks, and her work on sum-free sets became a standard reference for its subject matter. She helped found several important organizations in combinatorics, developed a researcher network, and supported young students with interest in mathematics.

**Mathematician #12: Charles Edward Miller Pearce**

Donate #12: RSPCA

Charles Edward Miller Pearce (29 March 1940 – 8 June 2012) was a New Zealand/Australian mathematician. At the time of his death on 8 June 2012 he was the (Sir Thomas) Elder Professor of Mathematics at the University of Adelaide.

He is known for probabilistic and statistical modelling. Pearce published prolifically in the area of probabilistic and statistical modelling and analysis, with strong contributions being made in both theory and practice. His book with Dragomir addresses the fine points of the Hermite–Hadamard inequality. His applied interests included queuing theory, road traffic, telecommunications, and urban planning. With former student Bill Henderson, who followed him from Sheffield to Adelaide, he helped establish the successful Teletraffic Centre in the University of Adelaide. Publications are numerous and include three books, 23 book chapters, and over 300 research articles.
