Our timeless Lord of Science, Dr Karl Kruszelnicki, is back - in this, his 37th book. Once again, The Doctor's mission has been to interpret the beauty and the mystery of the scientific world around us - alerting us to the complexities and conundrums of the everyday. He transcends history and space in his unstoppable quest to unearth scientific truths: from the theories of time travel, movie audiences emitting chemicals, an exploration of the spleen and red-blood cells to Bitcoin, dirty data, immortal jellyfish and how hot tea cools you down. The Doctor is the most trusted science communicator of our time.
Dr Karl Kruszelnicki is the Julius Sumner Miller Fellow at the University of Sydney. He is a qualified medical doctor, engineer, physicist and mathematician. He consistently appears on the list of the Top 15 Most Trusted Australians, and has been named one of Australia's National Living Treasures.
