The best talk ever1!!!!! Hyperbolic Hyperbole

Rachel Bunder http://lca2018.linux.org.au/schedule/presentation/145/ In 2005 the sisters Christine and Margaret Wetheim started to build the hyperbolic crochet reef project. They wanted highlight the damage done to coral reefs due to global warming using craft as the launch pad. This has been a phenomenal success with more than 8,000 people participating in coral reefs projects around the world, including a Sydney reef in 2009. But what is meant by hyperbolic? How did crochet get involved? In this talk we see the highlights of the 2000 year history of hyperbolic geometry that led to mathematician Daina Taimina realising that she could crochet these objects. This talk was given at Linux.conf.au 2018 (LCA2018) which was held on 22-26 January 2018 in Sydney Australia. linux.conf.au is a conference about the Linux operating system, and all aspects of the thriving ecosystem of Free and Open Source Software that has grown up around it. Run since 1999, in a different Australian or New Zealand city each year, by a team of local volunteers, LCA invites more than 500 people to learn from the people who shape the future of Open Source.
