Science and technology are inseparable. In the context of modelling and simulation as a tool that researchers employ to uncover hidden truths in their subject matter, platforms are enablers that allow us to push the limits of precision, complexity and ultimately, scientific productivity. These platforms take the shape of physical or virtual representations of subsets of reality, allowing us to focus intellectual resources on that which is of most interest while cutting out the negligible.

A borehole radar survey conducted prior to the start of the mining process improves mine planning and ensures that less waste is mined. Borehole radar systems are the tools used to conduct these surveys. The technique has been used successfully to delineate reefs and other geological features in South African gold and platinum mines.

High performance computing (HPC), often referred to as supercomputing, is a technology area in the broader domain of information and communications technologies (ICTs). At the most basic level, the purpose of HPC is to enable computer software with demanding computational requirements to be executed in acceptable time frames. The pieces of software are typically aimed at solving research problems in the scientific and engineering world, but there are also many examples of commercial and industrial applications that utilise HPC. The matters of computational requirements and acceptable time frames often go hand-in-hand, which is simply demonstrated by the intuition that an increase in the number of processing cycles per second will yield results in less time than before. In HPC, the aim is thus to enable the solution of computational problems that are so large and complex that they could not be addressed feasibly by conventional techniques.

Mandated by the Department of Science and Technology, the Centre for High Performance Computing (CHPC) aims to enhance the computational research output of the South African scientific computing community. High profile projects in material science, astrophysics, oceanography, climatologies, bioinformatics, fluid dynamics, finite element modelling, astronomy, high energy physics and quantum computing modelling are currently utlising the CHPC computational infrastructure.

The CSIR has gained considerable experience in simulation visualisation within the recent past due to the prominence of its simulation work. One of the tools that has evolved considerably during this time is the Cyclops visualisation and visual analysis tool. The current version, Cyclops 2, has been under development since 2005.

The majority of people living in rural areas of developing and underdeveloped nations have not yet been able to take advantage of the internet revolution. This increasing gap between the technology-enabled sections of human society and the underdeveloped rural population has created a 'global digital divide'. Most of the research focus to date has been around improving connectivity in urban areas while rural areas often have very little or no connectivity options.

Physical scale modelling offers an attractive alternative to conventional numerical modelling for predicting the response of a geophysical system. Recent experimentation with modern potting and casting materials, such as various types of resins, has rekindled the interest in scale modelling. In particular, the use of transparent resins enables one to construct models that can be used primarily for demonstration purposes, but which can also serve as scale modelling and calibration facilities.
