Making Waves
What conditions could cause geometric patterns to form on the surface of a liquid? Not just in a lab, but perhaps on the open sea as well? Hannah and Dara investigate!
What happens when you give water a really good shake? You might expect splashing, spilling and general aquatic chaos - but under exactly the right conditions, something much stranger can happen...
In this episode, Hannah Fry and Dara 脫 Briain dive into the world of 'Faraday waves': amazing geometric patterns that, in certain circumstances, will appear on the surface of a vibrating liquid. They discover how the renowned physicist Michael Faraday accidentally discovered this remarkable phenomenon in the 19th Century; debate whether they could ever occur in a swimming pool; and find out what on earth alligators have to do with it.
Along the way, the pair encounter eerie 鈥榮quare鈥� seas and learn about new ways satellites are helping us to understand the ocean鈥檚 wildest waves!
