About the Mahony Neumann Room Prize This prize, for outstanding contributions to the Australian Mathematical Society’s research publications, is fittingly named after the founding editors of those journals.…


Approximate solutions to one-phase Stefan-like problems with space-dependent latent heat

Stefan problems are a special type of partial differential boundary value problems, introduced around 1890 by the Slovenian physicist Josef Stefan [1].…


Watch: Ventilation and COVID-19

Experiments visualising the airflow when breathing, speaking and laughing, show that wearing a mask indoors can drastically reduce the risk of transmission of airborne particles.…


Watch: How do Sperm Swim?

The tail (flagellum) of the sperm does not simply push the body, but uses a rhythmical beating with pushing and fraying over a 4-beat pattern, as demonstrated in the video.…


Watch: How do Birds Fly in Strong Winds?

When navigating strong crosswinds birds adjust the angle of their body into the wind, whilst keeping their head fixed on the target destination, in order to maintain forwards motion.…


Watch: Underwater Robots based on the Loch Ness Monster

Current underwater vehicles are either difficult to manoeuvre making them unsuitable for sensitive work, or are extremely expensive. Gabe Weymouth and his team at the University of Southampton are designing new underwater robots based on the Plesiosaur – the dinosaur behind the legend of the Loch Ness Monster – which are much smaller, cheaper and more energy efficient.…
