Prepare yourself for bonus awesome content and watch Dr Karl pop up and introduce each chapter. There’s so much extra stuff, it’s like a book-within-a-book. Click on the hotspot links to access more information related to the topics in his latest book ‘Dr Karl’s Surfing Safari Through Science’. Among other things, Dr Karl asks: - Why can sharpening a pencil in space kill you? - What does a red sunset mean fine weather tomorrow? - How far would the Earth's viruses reach if you laid them end to end? - How can dead fish, and whales, keep swimming – after they’re dead? To experience the Dr Karl ‘holograms’ in augmented reality (AR), you’ll need the trigger images within the book. These are the front cover and the first page of each chapter. If you’d like a taster of the book without the entire stories, you can simply download the trigger images from the Help page within the application and access the augmented reality content by following the instructions. If you’re looking for the AR content for the previous book: ‘Dr Karl’s Random Road Trip Through Science’, don’t worry, it’s all still available through the app! Just look for the Random Road Trip footer in the app to access all that sciency goodness too! The Dr Karl App was developed by the awesome team at auggd.com. Videos were produced with support from the Media Room in the Faculty of Arts and Social Sciences, University of Sydney. The loading image of a Dr Karl shirt is by Luisa Brimble for frankie magazine. Thanks to you all.

About

Speak Dhurga

Features
Read full description

Speak Dhurga is one result of a years long collaboration project, Growing Yuin Languages. Contributors to this project include Merrimans Local Aboriginal Land Council, the Wallaga Lake Koori Village and Bermagui Communities, the Red Cross, Bega Valley Shire Council and teachers and students at Bermagui Public School. All spellings of Dhurga works and phonemes are taken from the Dhurga Dictionary and Learner's Grammar by Patricia Ellis, Kerry Boyenga and Waine Donovan. This app contains a mere snapshot of the language as described in this incredible dictionary. We acknowledge the original custodians of the land on which this app was built, the Brinja-yuin and Djiringanj people of the Yuin nation, and pay respect to their elders past, present and emerging who fought so hard to keep the Dhurga language alive. We also wish to acknowledge the traditional owners of the land on which you use this app.
