The Demon Haunted World – Carl Sagan *****

An eloquent plea for reason and the scientific method when the media are pumping unexplained phenomena and X-Files fiction at us all the time. There’s nothing wrong at all with science fiction or fantasy, as long as we are aware that’s what it is – but Sagan points out just how easy it is for us to believe that the ‘truth is out there’ just because we want it to be.
Everything from presidents consulting horoscopes to witch burning and miracle cures come under Sagan’s logical but still human eye. Whether your demons are traditional or modern world alien abductors, spirit mediums or faith healers, he painstakingly shows that we are much more likely to invent the supernatural than to experience it for real.
Although Sagan goes on a bit, it’s a great counter to wide-eyed acceptance – as useful in business as it is in dealing with the unexplained. The cover asks ‘Are we on the brink of a new Dark Age of irrationality and superstition?’ and it’s a question anyone with an interest in science has to face up to.
Perhaps the only weakness Sagan doesn’t face is the scientists who have don’t take a scientific, rational view (‘let’s test this theory with experiment’) but instead refuse to even consider phenomena outside of their experience (‘There’s no point looking into it; it doesn’t exist.’) But we definitely need a few more sceptical works like this to put along the uncritical pap that TV companies regularly feed into our homes as ‘documentaries’.

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
