Marcus Chown graduated from the University of London in 1980 with a first class degree in physics. He also earned a Master of Science in astrophysics from the California Institute of Technology. With much experience writing for magazines such as New Scientist, Chown has written a string of successful popular science books. His latest title is A Crack in Everything . Why black holes? I thought there was a fascinating, and largely untold, story about how black holes, once considered so ridiculous as to not even be the preserve of science fiction, have moved relentlessly into the centre of science over the past century. They evidently play some key but mysterious role in the universe, creating all we see around us and even explaining why we are here at all. But what that is nobody knows. What I am talking about is 'supermassive' black holes. There is one in the heart of every galaxy, and some have huge masses of tens of billions of times that of the sun. What they are doing there?
We've all got a favourite bit of technology that has been 'coming soon' for decades. Nicole Kobie takes us through the historical journey to the present for a range of such technologies from flying cars to robots (more detail in a moment). In each case these technologies seemed achievable many decades earlier, but the reality has been that making the dream real proved much harder than most envisaged (especially the inventors and investors). Kobie takes us through driverless cars, AI, robots, augmented and virtual reality (AR/VR), cyborgs and brain interfaces, flying cars, Hyperloops and smart cities. Many of these topics are much discussed, but it's really helpful seeing them all pulled together to get an overview of the way that we repeatedly get drawn into failed investments of time and money into a science fictional future without thinking enough about the practicalities of making it happen. My least favourite section was smart cities - I think most people (once Hype
