Our third annual pilgrimage to Sydney took us right back to Dr Karl's office. His brand new book, Dr Karl's Random Road Trip Through Science, features an Augmented Reality app with Dr Karl popping out of the book to share his wealth of wisdom. (If you've been listening to the show for a few years, this is certainly 'breaking the script' and is a definite 'purple cow'). We talk about a bunch of random scientific things Karl learnt this year, as well an injecting a nice amount of conspiracy theory too.  Check out more Dr Karl and grab his free AR app: https://drkarl.com/ Listen to our previous two episodes with Dr Karl: https://whatyouwilllearn.com/doctorkarl/ and https://whatyouwilllearn.com/drkarl-round2/ Hosted on Acast.
