Extraction to Extinction - David Howe ****

In this book, David Howe manages the near-impossible - making geology interesting. Usually, this is one of those dull, earnest sciences that it's hard to get too excited about. It might be a slight exaggeration, but for many of us, when you've seen one rock, you've seen them all. But Howe overcomes this issue with a combination of engaging storytelling and combining information about geology with how we humans have made use of them and the materials made from them - the book absolutely comes alive whenever we move from how the rocks were formed to how they have been used (and abused).

That storytelling element captured me from the first sentence: Howe had me at 'I was standing on Alderley Edge when I first wondered about it.' I admit that this is partly a matter of personal identification with the story. I too went to school in Manchester and explored Alderley Edge as a teen - I was a fan of Alan Garner, and even (not entirely licitly) ventured down the copper mines that Howe describes.

As far as the applications side goes, we tend to take for granted the availability of the raw materials extracted from the Earth that go to make up familiar objects, but as Howe takes us through the origin stories of brick and ceramics, copper, iron and steel, concrete, glass, aluminium, plastics and lithium and the rare earth elements, he both makes these everyday objects appear far more special and puts them into their context in the bigger picture of nature.

We then get the least satisfactory part of the book, where Howe takes us through the downside of our overuse of the Earth's resources and of the pollution and greenhouse gas production that results. It's not that these are unimportant issues, but they need a book in their own right to be as nuanced as the rest of the contents - having a couple of chapters on the subject just takes away from the rest of the book without being able to explore the issues properly. (There is, for example, no real mention of the need to balance out inconsistent sources like wind and sun, particularly somewhere like the UK, with storage and, almost certainly, nuclear.)

Things pick up again with the final chapter on the debated topic of whether we are now in the 'Anthropocene' epoch, where the reader is presented with the beguiling concept of future geologists finding layers in the Earth that correspond to what humans are doing at the moment. The only opportunity potentially missed here was to open up the debate as to whether this is a true epoch or a geological event.

Every now and then, usually when trying to be humorous, Howe's writing style becomes rather old fashioned - for example 'There appears to be a population of bevvy-swilling bozos who, wishing to show their strength by crushing flat their drained cans and then tossing them out of their car windows lend support to the Yorkshire proverb "Strong int'arm and thick in't head"' - but mostly I found this an enjoyable and thought-provoking read.

Roger Highfield - Stephen Hawking: genius at work interview

Roger Highfield OBE is the Science Director of the Science Museum Group. Roger has visiting professorships at the Department of Chemistry, UCL, and at the Dunn School, University of Oxford, is a Fellow of the Academy of Medical Sciences, and a member of the Medical Research Council and Longitude Committee. He has written or co-authored ten popular science books, including two bestsellers. His latest title is Stephen Hawking: genius at work . Why science? There are three answers to this question, depending on context: Apollo; Prime Minister Margaret Thatcher, along with the world’s worst nuclear accident at Chernobyl; and, finally, Nullius in verba . Growing up I enjoyed the sciencey side of TV programmes like Thunderbirds and The Avengers but became completely besotted when, in short trousers, I gazed up at the moon knowing that two astronauts had paid it a visit. As the Apollo programme unfolded, I became utterly obsessed. Today, more than half a century later, the moon landings are

Space Oddities - Harry Cliff *****

In this delightfully readable book, Harry Cliff takes us into the anomalies that are starting to make areas of physics seems to be nearing a paradigm shift, just as occurred in the past with relativity and quantum theory. We start with, we are introduced to some past anomalies linked to changes in viewpoint, such as the precession of Mercury (explained by general relativity, though originally blamed on an undiscovered planet near the Sun), and then move on to a few examples of apparent discoveries being wrong: the BICEP2 evidence for inflation (where the result was caused by dust, not the polarisation being studied),  the disappearance of an interesting blip in LHC results, and an apparent mistake in the manipulation of numbers that resulted in alleged discovery of dark matter particles. These are used to explain how statistics plays a part, and the significance of sigmas . We go on to explore a range of anomalies in particle physics and cosmology that may indicate either a breakdown i

Splinters of Infinity - Mark Wolverton ****

Many of us who read popular science regularly will be aware of the 'great debate' between American astronomers Harlow Shapley and Heber Curtis in 1920 over whether the universe was a single galaxy or many. Less familiar is the clash in the 1930s between American Nobel Prize winners Robert Millikan and Arthur Compton over the nature of cosmic rays. This not a book about the nature of cosmic rays as we now understand them, but rather explores this confrontation between heavyweight scientists. Millikan was the first in the fray, and often wrongly named in the press as discoverer of cosmic rays. He believed that this high energy radiation from above was made up of photons that ionised atoms in the atmosphere. One of the reasons he was determined that they should be photons was that this fitted with his thesis that the universe was in a constant state of creation: these photons, he thought, were produced in the birth of new atoms. This view seems to have been primarily driven by re
