Continuing with our Physics in Everyday Life series, in celebrating this year’s National Science Week, we bring you a mini-documentary on how physics can help us address energy, load-shedding, climate change and rural development challenges. We share how physics contributes to improving the nexus of Energy, Water, Climate and Food Security.In addition, understand how physics is improving the quality of life and sustainable development of our South African rural and previously disadvantaged communities by providing clean water, clean energy and supporting agriculture.
