The science they didn’t teach you at school

We’ve got a new sister site, sciextra.com – it contains short pieces from our editor, Brian Clegg, on the science they didn’t teach you at school. The really interesting bits. The bits that make you go ‘Wow!’
It’s early days, but there’s new content going up every week. The material is a mix of short written pieces and videos. These videos don’t set out to be all hi-tech and broadcast quality. The aim is just to get the ideas across quickly and simply.
Please do click through and take a look at the site, but for a taster here’s one of the videos, answering the question ‘If time travel is possible, why aren’t we inundated with visitors from the future?’

On the Fringe - Michael Gordin *****

This little book is a pleasant surprise. That word 'little', by the way, is not intended as an insult, but a compliment. Kudos to OUP for realising that a book doesn't have to be three inches thick to be interesting. It's just 101 pages before you get to the notes - and that's plenty. The topic is fringe science or pseudoscience: it could be heavy going in a condensed form, but in fact Michael Gordin keeps the tone light and readable. In some ways, the most interesting bit is when Gordin plunges into just what pseudoscience actually is. As he points out, there are elements of subjectivity to this. For example, some would say that string theory is pseudoscience, even though many real scientists have dedicated their careers to it. Gordin also points out that, outside of denial (more on this a moment), many supporters of what most of us label pseudoscience do use the scientific method and see themselves as doing actual science. Gordin breaks pseudoscience down into a n

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
