Theoretical physicist and science communicator Professor Jim Al-Khalili has taken a break from writing popular science books to write his first novel. Sunfall (£16.99, Bantam Press) is a science fiction thriller set in the year 2041, when the Earth’s magnetic field has started to die, leaving life on Earth vulnerable to threats from space.Scientists and engineers are thrown into a race against time to protect the Earth. All the science in the novel, from the futuristic technology to the apocalyptic event, are based on real science, as we understand it now.In this episode, Jim explains how the Earth’s magnetic field protects us, how being a scientist helped inform his writing, and why fiction can be a frontier for science communication.If you like what you hear, then please rate, review, and share with anybody you think might enjoy our podcast.You can also subscribe and leave us a review on your favourite podcast apps. Also, if there is anybody you’d like us to speak to, or a topic you want us to cover, then let us know on Twitter at @sciencefocus.Listen to more episodes of the Science Focus Podcast:How can we save our planet? - Sir David AttenboroughWhy is the magnetic north pole moving? - Ciaran BegganThere is no Plan B for planet Earth – Lord Martin ReesWhy AI is not the enemy – Jim Al-KhaliliIs there anybody out there? – Mike GarrettBuilding a base on the Moon, and crafting believable sci-fi – Andy WeirFollow Science Focus on Twitter, Facebook, Instagram and Flipboard See acast.com/privacy for privacy and opt-out information.

Do you believe in magic? – Gustav Kuhn

April 03, 2019 29:11 28.03 MB Downloads: 0

Abracadbra! Prestidigitation! We know that these words hold no intrinsic power, but when we hear them, we are instantly transported away to a land of magic and wonder; where the impossible becomes reality right before our eyes.So why, as rational human beings, are we instantly drawn to magic, and what makes us delight in seeing a rabbit pulled from a hat, despite knowing full well that we are being fooled into thinking it was never already there in the first place?Those are the sort of questions expert in cognitive psychology, magician, and author of Experiencing the Impossible: The Science of Magic (£20.00, MIT Press), Gustav Kuhn, is currently trying to solve at his Magic Lab at Goldsmith’s University.In this week’s Science Focus Podcast, he talks to sciencefocus.com editor Alexander McNamara about why we believe in magic, what actually happens in our brain when we watch tricks, and how understanding magic can help us make sense of a world filled with fake news and misinformation.Image © Getty Images See acast.com/privacy for privacy and opt-out information.
