The Future of the Mind – Michio Kaku ***

Physicist Michio Kaku, an expert in string theory, might not seem the obvious person to take us on a tour of what the subtitle describes as ‘the scientific quest to understand, enhance and empower the mind.’ But Kaku is a very experienced science communicator and though I didn’t feel the same deep connection with, and love for, his subject as comes across in his physics-based books, there is certainly a lot to ponder in this reasonably chunky bit of scientific futurology.
Of all the great science popularisers – and I don’t hesitate to put him in that bracket – Kaku is the most deeply immersed in the science fiction tradition. For every example of a scientific idea he has a story to put it into context, which if you like SF, as I do, is a great asset. The only slight problem this makes for is that when Kaku extrapolates a piece of current technology into the future he tends to oversimplify the problems and goes far too far. So, for instance, an experiment where monkeys are led to feel the sense of touch from a remote sensor leads us to Kaku prompting an interviewee to say ‘I think this is the first demonstration that something like the [Star Trek, the Next Generation] holodeck will be possible in the near future.’ This is almost the definition of hyperbole. My suspicion is that physicists make better science fiction writers than futurologists.
Throughout the book we visit different aspects of the brain and the mind and how they might in the future be enhanced. This often involves finding out more about current brain conditions and injuries, as these have frequently resulted in discovering more about the workings of this most remarkable organ. Kaku quotes a mind-boggling example of a patient with a split brain. Without the usual connection of the corpus callosum, the left and right sides of the brain can hold different opinions and have different feelings. We hear of a patient whose left brain was atheist and right brain was a religious believer – a quite remarkable state of affairs. The ‘learning through damage and illness’ bit is necessary, but after a while, hearing about all these failings of the brain does get a little wearing.
Along the way we experience mind-to-mind communication, mind controlling machines, intelligence enhancement (though strangely with hardly any overlap with Smarter), artificial intelligence, disembodied minds and more. There’s a lot of good material here, but somehow I found reading it a little too much like hard work, rather than the feast of ideas we often get in one of Kaku’s books. Interesting, but not one of his best.

A (Very) Short History of Life on Earth - Henry Gee *****

In writing this book, Henry Gee had a lot to live up to. His earlier title  The Accidental Species was a superbly readable and fascinating description of the evolutionary process leading to Homo sapiens . It seemed hard to beat - but he has succeeded with what is inevitably going to be described as a tour-de-force. As is promised on the cover, we are taken through nearly 4.6 billion years of life on Earth (actually rather more, as I'll cover below). It's a mark of Gee's skill that what could have ended up feeling like an interminable list of different organisms comes across instead as something of a pager turner. This is helped by the structuring - within those promised twelve chapters everything is divided up into handy bite-sized chunks. And although there certainly are very many species mentioned as we pass through the years, rather than feeling overwhelming, Gee's friendly prose and careful timing made the approach come across as natural and organic.  There was a w

Michael D. Gordin - Four Way Interview

Michael D. Gordin is a historian of modern science and a professor at Princeton University, with particular interests in the physical sciences and in science in Russia and the Soviet Union. He is the author of six books, ranging from the periodic table to early nuclear weapons to the history of scientific languages. His most recent book is On the Fringe: Where Science Meets Pseudoscience (Oxford University Press). Why history of science? The history of science grabbed me long before I knew that there were actual historians of science out there. I entered college committed to becoming a physicist, drawn in by the deep intellectual puzzles of entropy, quantum theory, and relativity. When I started taking courses, I came to understand that what really interested me about those puzzles were not so much their solutions — still replete with paradoxes — but rather the rich debates and even the dead-ends that scientists had taken to trying to resolve them. At first, I thought this fell under

Regeneration - Paul Hawken **

This is a really big book. I don't mean big in the sense of important, but physically enormous for what it is - it's roughly the size of a children's annual, though a lot thicker. Interestingly, the format appears to be a Paul Hawken speciality - he did it with his previous title, Drawdown ,  though that was far less glossy. Paul Hawken's aim is to put forward a solution to climate change driven from humans rather than from the science. The tag line on the back of the book reads 'The climate crisis is not at science problem. It is a human problem.' And that itself is a problem. It's not that climate change isn't a human problem, but rather that it's both a human problem and a science problem - requiring human and science-based solutions. But the approach taken in this book is anything but scientific. It's a bit like saying the Covid-19 pandemic is a human problem, not a science problem. The pandemic is indeed a human problem, but if we'd tr
