# Professor Rowena Ball

## Contacts

I am an applied mathematician and physical chemist with broad research expertise in nonlinear and complex dynamical systems. My ARC Future Fellowship is entitled - “The charXive challenge and the clean coal quest: thermokinetic principles and methods for capturing and sequestering carbon dioxide." The next 50 years will be the era during which the world's fuels must be decarbonised. Endex thermoreactive principles, which I co-invented in the mid 1990s, are providing a novel technology for separating carbon from fuels and flue gases. I am developing a suite of Endex decarbonation technologies in collaboration with an industry partner, Calix Ltd, and with collaborators from Imperial College London, the University of Leeds, and CanMet Energy. Endex principles also underpin carbon capture from the atmosphere and have been used by nature for millions of years: the mechanism behind thermal decomposition of biomass is an Endex thermochemical oscillator that governs the distribution of carbon between the global solid black carbon reservoir and the atmospheric CO2 reservoir. My research is elucidating this mechanism.

### Research interests

***Student Scholarship available***

A full scholarship is available for an Indigenous student to undertake an MPhil or PhD research degree within my Mathematics Without Borders group at ANU, Canberra.

Choice of research topic is flexible, depending on the student's interests, background, and career aspirations. Possible research areas may include -

- Fluid dynamics simulations of smoke, in relation to Indigenous smoke-signalling codes and new management strategies for bushfires and cultural burning

- Tracing the origins and usages of mathematical transforms and other mathematical objects and processes through Indigenous and non-Western cultures

- Modelling aspects of the human neurophysiology of mathematical expression to help understand questions about the origins of mathematics, such as pattern recognition, cognition of cyclic phenomena, and numbers

- Truth-telling in mathematics history and cultures; tacking unbridled Eurocentrism and coloniality in mathematics

- Other exciting projects are under development

Get in touch if you would like to become a key contributer to this dynamic and rapidly expanding research program!

**Research Keywords:**

Mathematics Without Borders, Truth-Telling in Mathematics History, Decolonisation of STEM, Indigenous and Non-Western Mathematics, Emergence of life, Nonlinear and complex dynamical systems, Thermochemical instabilities and oscillators, Thermodynamic analysis, Railways and trains, Country pub lunches

What is mathematics? What is included in mathematics? Who gets to say? How and why did Western mathematics exclusively colonise minds and curriculums over the whole world? Should that situation continue unabated?

In this suite of research projects we investigate the mathematical knowledges of non-Western and Indigenous societies, truth-telling in mathematics history, vernacular mathematical practices, and neurology of mathematical expression.

http://anu.academia.edu/RowenaBall. Summary: Two published examples of incorrect and dangerous thermal runaway criteria are exposed. Stability theory has been used by chemical engineers to assay reactive thermal hazard for sixty years - why has this knowledge been completely ignored by the authors of those works? They claim to specify thermal 'safety' criteria but, to the contrary, they are seriously putting human lives at risk. - Plouffe, P, Gamage McEvoy, J, Ball, R et al 2012, 'Object-oriented simulation of an Endex reactor for separation of carbon dioxide from flue emissions', Computers in Chemical Engineering, vol. 40, pp. 213-222.
