Amplifying New Voices And Making Space For Alternative Knowledge Systems In Engineering Curricula – The Example Of Ubuntu, Anita Occhio, Fiona Caroline Saunders, Gladson Chikwa, Dawn Theresa Nicholson

Practice Papers

Engineering projects are ubiquitous; from developing COVID-19 vaccines to building new cities and developing climate change solutions. An inclusive approach to teaching engineers how to master the complexities of engineering project management is vital to the deliverability of sustainability and net zero initiatives (Hockings 2010). Yet, our engineering curricula remain deeply rooted in Western epistemology (Winter et al. 2022, Mbembe 2015). Arguably, this is an opportune time to consider decolonising our curricula. At a fundamental level, ‘decolonising the curriculum’ means introducing previously ignored voices, images, authors, theories and arguments into our teaching (Rogers et al. 2022). This is a challenge …

On The Mandelbrot Set For I**2 = ±1 And Imaginary Higgs Fields, Jonathan Blackledge

Articles

We consider the consequence of breaking with a fundamental result in complex analysisby lettingi2=±1wherei=√−1is the basic unit of all imaginary numbers. An analysis of theMandelbrot set for this case shows that a demarcation between a Fractal and a Euclidean object ispossible based oni2=−1andi2= +1, respectively. Further, we consider the transient behaviourassociated with the two cases to produce a range of non-standard sets in which a Fractal geometricstructure is transformed into a Euclidean object. In the case of the Mandelbrot set, the Euclideanobject is a square whose properties are investigate. Coupled with the associated Julia sets and othercomplex plane mappings, this …
