When the movie Interstellar was released in 2014, I thought its depiction of a black hole was one of the most hauntingly beautiful scenes. And with input from prominent astrophysicist Kip Thorne, there was plenty of science to this piece of science fiction (see The Science of Interstellar). Amazingly, we only had to wait five more years for an actual image of a black hole – or really its event horizon – to be published. But these astounding images have been a long time coming. With Gravity’s Century, science writer Ron Cowen traces the story back to Albert Einstein and provides an accessible and compact overview of the century-long quest in physics to better understand gravity.
Judging by the title of this book, you might expect it to talk of 25 remarkable kinds of rocks and minerals. But in the preface, geologist and palaeontologist Donald R. Prothero makes clear that his book looks as much at famous outcrops and geological phenomena. Bringing together 25 readable and short chapters, he gives a wide-ranging tour through the history of geology, celebrating the many researchers who contributed to this discipline.
Asteroids and comets have a bad reputation. Looking back over the books I have reviewed, they usually come up in the context of impact and destruction. But there are other important reasons to study them and geologist and cosmochemist Natalie Starkey here steps up as their enthusiastic spokeswoman. Whether as frozen time capsules, possible vehicles dispersing the basic chemicals required for life, or even future mining quarries, Catching Stardust champions the importance of scientific research on these celestial objects.
The idea of an asteroid or comet impacting with planet Earth and causing a catastrophe for mankind has long been given a cold shoulder in scientific circles. But with the notion that the dinosaurs met their fate at the hand of a rather large space rock it does not seem so outlandish anymore. NASA has started monitoring near-earth objects, but is there really something we could do if one was heading our way? Astrophysicist and science writer Andrew May provides a delightful little primer on these questions with Cosmic Impact, injecting this oft-hyped topic with a healthy dose of realism.
Humans have been gazing at the stars since times immemorial. Once we understood what stars were, and that our planet together with others circled one such star, it was only a small step to think that there must be other planets outside of our Solar System. But only in the last 25 years have we been able to start finding these so-called exoplanets. Astronomer Donald Goldsmith here promises, and delivers, an introduction that even an astronomy novice such as myself could understand and thoroughly enjoy.
What an appropriately punny title. Indeed, the Voyager Golden Records have boldly gone where no records have gone before. A record with images, spoken greetings, everyday sounds, and classical, contemporary and world music intended as an interstellar hello. Writer, record collector, and self-professed astronomy geek Jonathan Scott here tells the story of one of the most unusual human artefacts to have ever been sent into deep space.
Our planetary neighbour Mars has long fascinated us, and the idea of there being Martian life holds a strong grip on our collective imagination. NASA and others are becoming serious about sending people to Mars. Before we do so, astronomy professor David Weintraub would like to give you this readable history of our fascination with the Red Planet and the research that tries to answer the question: is there life on Mars? (Admit it, you were crooning that David Bowie song there).
Starting your book blurb by asking why gazelles have legs rather than wheels is a suitably out-there question to immediately grab a reader’s attention. A more pertinent question then; why is all life based on carbon rather than silicon? In The Equations of Life, Charles Cockell takes the reader on a giddy tour down the organisational hierarchy of life – from sociobiology to subatomic particles – to show that nature is far more predictable and understandable than it might appear at first blush. His eloquent answer to above and other why questions? “Because physics is life’s silent commander”.
If you have used a compass, you will know our planet has a magnetic North and South pole. You might even be aware that the geographical and magnetic poles are not exactly in the same location. The magnetic poles have a tendency to wander with time. They can even swap places, and we have evidence of a long history of such geomagnetic reversals in the rock record. But how does this happen? And what would the consequences be if this happened today? Earth’s magnetic field offers protection against radiation from outer space, primarily from the sun, so if this field weakens or changes, what will happen to us and our electrical infrastructure? Join science journalist Alanna Mitchell as she explores this topic and delves into the history of electromagnetism.
