Exploring the World of Non-Newtonian Fluids: A Journey with Professor Michael Cates

On Thursday 25 April, six Year 12 Physics students attended a thought-provoking lecture at the Royal Society by Professor Michael Cates from the University of Cambridge.

The lecture focused on "Bullet-proof Custard" and delved into the fascinating world of non-Newtonian fluids. Initially challenging, Professor Cates' explanations gradually made the topic more accessible, highlighting the relationship between stress levels, viscosity, and friction-dependent density. One intriguing example discussed was the application of Oobleck in chocolate making, demonstrating how non-Newtonian fluids retain their properties even when mixed with solid substances through processes like conching.

The lecture was both informative and enjoyable, providing valuable insights into theoretical and material physics.
