the-universe-in-100-key-discoveries-by-giles-sparrowThe Universe in 100 Key Discoveries, Giles Sparrow (Quercus 2012)

Possibly the best book I’ve ever read on astronomy: text and images complement each other perfectly. Even the solidness of the book was right. It’s a heavy book about heavy ideas, from the beginning of the universe to its possible endings, with everything astronomical in between.

And everything is astronomical, if it’s looked at right. The elements vital for life were cooked in stars before being blasted out by supernovae. We are star-stuff that has the unique privilege – so far as we know – of being able to understand stars.

Or trying to. This book was first published in 2012, so it’s inevitably out of date, but many of the mysteries it describes are still there. And when mysteries are solved, they sometimes create new ones. Even the behaviour and composition of a celestial body as close as the Moon is still impossible for us to explain. But sometimes it’s easier at a distance: the interior of the earth can harder to study than galaxies millions of light years away, as I pointed out in “Heart of the Mother”.

In every case, however, understanding depends on mathematics. Astronomers have been building models of the heavens with shapes and numbers for millennia, but the models had to wait for two things to really become powerful: first, the invention of the telescope; second, the development of modern chemistry and physics. Whether or not there is life out there, celestial light is full of messages about the composition and movement of the stars and other bodies that generate it.

But visible light is only a small part of the electromagnetic spectrum and modern astronomy probes the universe at wavelengths far above and below it. The more data astronomers can gather, the more they can test the mathematical models they’ve built of the heavens. The best models make the most detailed predictions, inviting their own destruction by ugly facts. But when predictions fail, it sometimes means that the observations are faulty, not the models. Cosmological models predicted much more matter in the universe than we can see. Is the gap accounted for by so-called “dark matter”, which “simply doesn’t interact with light or other electromagnetic radiations at all”? (ch. 98, “Dark Matter”, pg. 396)

Dark matter is a strange concept; so is dark energy. Astronomy may get stranger still, but the cover of this book is a reminder that human beings inhabit two kinds of universe. One is the universe out there: matter and radiation, moons, planets, stars, galaxies, supernovae. The other is the universe in here, behind the eyes, between the ears and above the tongue. The cover of this book offers a vivid contrast between the swirling complexity and colour of a star-field and the sans-serif font of the title and author’s name. But the contrast is ironic too. The stars look complex and the font looks simple, but language is actually far more complex and difficult to understand than stars.

Consciousness may be far more complex still. In the end, is the value of science that it expands consciousness, offering new physical and mental sensations of discovery and understanding? The powerful and beautiful images and ideas in this book could only have been generated by science, because the universe is more inventive than we are. But without consciousness, the universe might as well not exist. Without language, we’d never be able to try and understand it. Then again, the universe seems to have invented language and consciousness too.

Philip’s Guide to Seashells (sic), A.P.H. Oliver, illustrated by James Nicholls (various dates)

Number is all, as the Pythagoreans recognized more than two millennia ago, but number is more obvious in some places than others. When you leaf through this book, you’re leafing through a catalogue of mathematical possibility: the endlessly varying shapes, sculptings, colours and patterns of seashells are in fact governed by evolutionary changes in a few relatively simple variables. The black-spotted, drill-like spiral of Terebra sublata might look very different from the orange-tinged, flattened, scorpion-like Lambis crocata, with its seven curved spikes, but the two species descend from the same ancestor as every other shell on display.

From the same ancestor as shell-less land- and sea-slugs too. But readers should remember that this book is a morgue as well as a museum: rich and beautiful as the shells are, the living animals and their biology are richer and more beautiful still. The living animals are sometimes deadly too: the very beautiful cone-shells have killed humans with their stings.

But the shell remains when the animal is dead, and can be collected and studied in isolation. That’s why almost all of the book is devoted to the more or less snail-like univalves, with the more or less scallop-like bivalves given only a few pages at the end. Generally speaking, univalve shells are much stronger and much more durable. They’re also more varied in both architecture and patterning: anyone who’s played with cascading cellular automata will often find the designs on the shells of cowries and cone-shells startlingly familiar. But they were doing it millions of years before us.

The cowries have a sexual charge too, with their tight, pudendal slits: their generic name, Cypraea, is taken from a title of Aphrodite, the Greek goddess of love. The apertures of other genera gape and glisten even more suggestively, imitating the labia of every human race and many abhuman ones. Is that part of the appeal of shell-collecting? I don’t know, but it doesn’t have to be, because it doesn’t appear in every shell and can’t be seen when the shells in which it does appear are turned over.

And they look better like that: Cypraea caputdraconis (sic), or the dragon’s-head cowrie, looks like unzipped black jeans lying on its back, but like a black, silver-flecked jewel lying on its front. It’s found only on Easter Island too, which is one of the many interesting snippets you can pick up from the short descriptions accompanying each highly skilled illustration.

But the illustrations aren’t, alas, as highly skilled as they could have been: in the reflections on many of them you can see the wooden dividers in the window of the room in which they were painted. That might have been quirkily attractive once or twice, but repeated over and over it becomes irritating. It could have been avoided, or the artist could have set up other reflections: palms, sea-birds, clouds, and even the moon or stars, as though the shells were still lying on a tropical beach.

Fortunately, it affects only the shiny and relatively undistorting surfaces of genera like the cowries and it’s only a minor blemish in a beautifully designed and well-written guide to a fascinating subject. And as always, the scientific names can have an appeal all of their own: we’ve already seen Cypraea caputdraconis, but what about Conus thalassiarchus, the Sea-Lord Cone, or Cirsotrema zelebori, whose meaning I have no idea of?

The Cactus Handbook (Der Kakteen Führer), Erik Haustein, translated by Pamela Marwood (Cathay Books 1988)

This book reminds me of the Philip’s Guide to Seashells, because it carries the same important themes: cacti can look very different, but they descend from a single common ancestor and their shape and color are governed by evolutionary changes in a few relatively simple variables.

But there is one big difference between shells and cacti: the shells are dead and don’t change any more; the cacti are living and do. That means that there can be a startling contrast between the vicious spikes or blistering hairs of a cactus, intended to permanently deter, and its beautiful flowers, intended to periodically attract. Notocactus ottonis, for example, is a ridged ball of tough green flesh set with dozens of spikes; its flowers are a beautiful little fountain of yellow petals. Parodia sanguiniflora has even more spikes and even more beautiful flowers: a spray of scarlet petals around a golden heart of anthers and stigma. If the book was scratch’n’sniff, the contrast would because even sharper, because the flowers often smell attractive too.

All of that is adventitious from the human point of view, because the flowers and scent aren’t intended to attract us. But they do, and so do the strangeness and toughness of cacti, which is why a German author has written a highly detailed guide to plants from South and Central America. Some could probably never be grown in Germany, being far too large and demanding even for a specialist greenhouse; others can be grown anywhere with simple equipment.

And once again, as with any sufficiently detailed book about plants or animals, the scientific names have an appeal of their own: Mitrocereus fulviceps isn’t properly illustrated and perhaps could never live up to its name, which means something like “wax-cap tawny-head”, while the name Gymnocalycium horridospinum combines beauty and threat in the way the plant itself does. Its spines are indeed “horrid”, but beautiful violet-pink flowers sprout between them.

The cone-shells provide a similar contrast between beauty and deadliness, but you don’t actually see the deadliness of a cone-shell. However, you need a specialist vocabulary to describe both cone-shells and cacti properly, and both these books will help you acquire one. Being dilettantish, I haven’t put the effort in, but I know I should do, because it would help me to a deeper and richer appreciation of what I’m looking at.

restless-creatures-by-matt-wilkinsonRestless Creatures: The Story of Life in Ten Movements, Matt Wilkinson (Icon 2016)

A fascinating book about a fascinating thing: the movement of plants and animals. It’s also a very familiar thing, but it’s far more complex than we often realize. Human beings have been watching horses gallop for thousands of years, but until the nineteenth century no-one was sure what was happening:

The man usually credited for ushering in the modern study of locomotion is the brilliant photographer Eadweard Muybridge. […] His locomotory calling came in 1872, when railroad tycoon and former California governor Leland Stanford invited him to his stock farm in Palo Alto, supposedly to settle a $25,000 bet that a horse periodically becomes airborne when galloping. (ch. 1, “Just Put One Foot in Front of Another”, pg. 16)

To answer the question, Muybridge used a series of still cameras triggered by trip-wires. And yes, galloping horses do become airborne: “not when the legs were at full stretch, as many had supposed, but when the forelimbs and hindlimbs were at their closest approach.” However, Matt Wilkinson calls another man “the true founding father of the science of locomotion”: the French scientist Étienne-Jules Marey, who had been investigating movement using a stylograph. In fact, it was Marey who first proved that galloping horses become airborne (ch. 1, pg. 19). Muybridge’s photographs were dramatic confirmation and the two men began to collaborate.

Marey also pioneered electromyography, or the recording of the electrical impulses generated by moving muscles. Like the rest of modern science, biokinesiology, as the study of animal movement might be called, depends on instruments that supplement or enhance our fallible senses. It also depends on mathematics: there is a lot of physics in this book. You can’t understand walking, flying or swimming without it. Walking is the most mundane, but also in some ways the most interesting, at least in its human form. Bipedalism isn’t an everyday word, but it’s an everyday sight.

What does it involve? How did it evolve? And how important was it in making us human? Wilkinson looks at all these questions and you’ll suddenly start seeing your legs and feet in a different way. What wonders of bioengineering they are! And what a lot of things happen in the simple process of “just putting one foot in front of another”. Scientists still don’t understand these things properly: for example, they can’t say whether or not sport shoes are dangerous, “lulling us into a false sense of security, causing us to pass dreadful shocks up our legs and spine without our being aware of them” (ch. 1, pg. 29).

But there’s much more here than horse and human locomotion: Wilkinson discusses everything from eels, whales, pterodactyls, bats and cheetahs to amoebas, annelid worms, fruit-flies, zombified ants and the “gliding seed of the Javan cucumber Alsomitra macrocarpa”. He also discusses the nervous systems, genes and evolution behind all those different kinds of movement. This book is both fascinating and fun, but I have one criticism: its prose doesn’t always move as lightly and gracefully as some of its subjects do. Wilkinson mentions both Stephen Jay Gould and Richard Dawkins. I wish he’d written more like the latter and less like the former. If he had, a good book would have become even better.

journey-to-the-centre-of-the-earth-by-david-whitehouseJourney to the Centre of the Earth: A Scientific Exploration into the Heart of Our Planet, David Whitehouse (Weidenfeld & Nicolson 2015)

Can you touch anywhere on your body with your right hand? Replying quickly, you might say you can. But what about your right elbow? You can’t touch that with your right hand. Science is like that, because distant things are often easier to study and understand than close things. We have a good understanding of how stars work, for example, but not of how the earth’s magnetic field is generated.

And while we’ve been able to predict solar eclipses for millennia, we still can’t predict earthquakes or volcanic eruptions. Understanding the deep earth is difficult, so there are a lot of mysteries and conjectures in this well-written and compelling book about the interior of our home planet. Scientists have landed probes on Mars, millions of kilometres away, but the “deepest hole ever drilled on earth – the Kola Superdeep borehole in northern Russia” reached only 12,262 metres. That’s a mere pinprick by comparison with the radius of the earth. To get beyond that, scientists have had to study the shockwaves generated by earthquakes. The medium is the message: as the waves pass through or hit different regions and materials, they behave in different ways.

For example, when the Croatian scientist Andrija Mohorovičić (1857-1936) “studied the records from several seismometers” after an earthquake near Zagreb, “he realised that some of the shockwaves […] were being reflected back to the surface from a boundary region between the crust and mantle.” (pg. 82 of the 2016 paperback) The region is now called the Mohorovičić discontinuity. But that discovery was made before the First World War and deep geology hasn’t advanced very much in the intervening century. This book borrows the title of a Jules Verne novel published in 1864. If Verne came back to life, he would be pleased to see that his work is still popular, but he would be disappointed to see that the human race was no nearer reaching the centre of the earth.

Or would he? The American geologist Don Anderson says: “Almost everything known or inferred about the inner core from seismology or indirect inference is controversial.” (pg. 211) Deep geology is a difficult science, but that’s part of what makes it so interesting. Something else that makes it interesting is that the inner earth can visit catastrophes on the outer earth and the film of the life that clings there:

The big question is: can we see mass extinction events on the way up? Some scientists believe that we can by looking for the plumes [i.e., giant plumes of rising magma]. Such a thing is seen in the south-west Pacific near the Fiji Tonga subduction zone. It’s 700 km deep, has a structure consistent with a massive temperature anomaly and may be rising. It could render the earth uninhabitable for humans and it will reach the surface in an estimated 200 million years. (ch. 17, “Plumes”, pg. 146)

Asteroid impact and gamma-ray bursts are not the only catastrophes that threaten the continued existence of the human race. They may not even be the most likely. The film of life on the surface of the earth is fragile and one day it won’t be there any more.

But there’s also life deep inside the earth, living in conditions of extreme pressure, heat and darkness. We still know little about this “deep biosphere” and it may hold some big surprises. The rest of the deep earth almost certainly does. And the deep earth is just the beginning: as Whitehouse describes in chapter 26, there are “Other Worlds, Other Journeys” to come, including the even more extreme conditions at the heart of Jupiter, where the temperature is a “staggering 37,000 degrees C” and the pressure is “over ten times that found at the centre of the Earth.” (pg. 239)

Or so scientists estimate. Will scanners be invented to prove their theories? Will probes ever get there and find out for real? We can hope so. In the meantime, this book is an excellent introduction to the ideas, the pioneers and the modern researchers into mysteries that are right beneath our doorsteps. Whether it’s discussing diamonds, demons or “Double-D-Prime”, Journey to the Centre of the Earth is popular science that’s interesting, entertaining and informative all at once.

british-butterflies-by-david-dunbarBritish Butterflies: A History in Books, David Dunbar (The British Library 2012)

This isn’t a book about British butterflies, but a book about books about British butterflies. There have been a lot of them and David Dunbar does a good job of providing a comprehensive guide for collectors. He begins with the Insectorum sive Minimorum Animalium Theatrum (1634), the Theatre of Insects or Tiny Animals, which is based on a manuscript by Thomas Moffet. Was Moffet the father of Miss Muffet of nursery-rhyme fame? Maybe. He was certainly a pioneer of British entomology and “the original Latin edition of Insectorum Theatrum must be regarded as the cornerstone of any collection of early entomological books”.

If you want that cornerstone, you’ll have to be rich: it was listed for £4,141.72 at Abe Books in 2016. I would be happy with a facsimile myself. I used to own a facsimile of perhaps the most famous book discussed here: Moses Harris’s The Aurelian (1766). Dunbar discusses the original, mentions the facsimile, and reproduces some of Harris’s beautiful illustrations showing butterflies and moths with their food plants. He explains the book’s puzzling title too: “Aurelian” is an old word for a lepidopterist and comes from Latin aurum, “gold”, referring to gold spots or colours on a chrysalis (from Greek khrysos, “gold”). The metamorphosis of lepidoptera from ugly or strange larva to inert chrysalis to light-winged adult is a large part of their appeal. Lepidoptera can be like flying flowers and have attracted artists for millennia.

For example, Hieronymus Bosch gave “the wings of meadow browns and small tortoiseshells” to demons in his painting The Garden of Earthly Delights (c. 1490). There’s nothing as strange as that here, but there are a lot of illustrations: almost every page has something attractive or interesting to look at, as Dunbar traces butterfly books from the seventeenth century to the twenty-first. He discusses artists like F.W. Frohawk (1861-1946) and scientists like E.B. Ford (1901-88), but he concentrates on bibliography, not biography. You’ll have to look elsewhere to learn that butterfly-fanciers have a lot in common with orchid-fanciers: they can be strange and obsessive people.

But then butterflies are Ballardian: they combine beauty with strangeness. On page 111 you’ll find the beauty in the colours and patterns of the Large Heath buttery; on page 110 you’ll find the strangeness in a series of “line drawings of butterfly genitalia” from The Genitalia of the British Rhopalocera and Larger Moths (1941).

The genitalia look like spiky seed-pods or torture instruments for aliens. They are still best represented as line drawings, but photography has gradually begun to dominate butterfly books, as you’ll see here. I prefer paintings and drawings myself. There’s a magic to art that resonates with the magic of butterflies, and true art has survived better in natural history illustration than it has in many other places. And Dunbar even has space to discuss butterflies on cigarette cards and wall-charts. He knows his subject inside out and this book about butterfly books proves it.

Blind Descent by James M. TaborBlind Descent: The Quest to Discover the Deepest Place on Earth, James M. Tabor (Random House 2010)

When men climb mountains, they confront their own minds. There are psychological barriers to conquer as much as physical ones: fear, uncertainty, mental fatigue. But all those barriers, psychological and physical, are bigger in caving – and particularly in the caving described in this book. It’s about the quest to explore super-caves, the deepest and most dangerous places on earth.

As a result, they’re also the most challenging. Climbing a mountain doesn’t cut you off from the sun, stars and sky or from easy communication with the rest of the world. Super-caving does and that isolation alone is difficult to endure as days underground stretch into weeks and months. It isn’t alone, of course: there are also wet, cold, dirt and constant danger down there. Sometimes deafening noise too, as underground rivers pour over waterfalls or churn through huge tunnels. But super-caving won’t make you famous: it isn’t as photogenic as mountaineering and the two great cavers discussed here, the Ukrainian Alexander Klimchouk and the American Bill Stone, aren’t household names.

Perhaps they never wanted to be. Mountaineers move towards the sun, higher and higher into the light. Cavers move away from the sun, deeper and deeper into the dark. It would be interesting to compare the psychology of the two groups. Some people belong to both, of course, and Tabor points out that exploring a super-cave is like climbing Everest in reverse. Except that Everest doesn’t drown people. Super-caves do, because to explore them cavers often have to don scuba-gear and swim through flooded tunnels and highly dangerous sumps. In that setting, mistakes and accidents that mean little in open water often become deadly. Like motorcyclists and heroin-addicts, cave-divers will tend to know a lot of people who died young.

And fear of dying can cause it: it’s easy to panic when the risks are so high and the pressures so great. Cave-diving is one of the biggest psychological challenges that a human being can face. Alexander Klimchouk and Bill Stone beat the odds, but only one of them could win the race Tabor describes here: reaching the lowest point on earth. Stone sought it in Mexico, Klimchouk in the Republic of Georgia. According to Tabor, Klimchouk won the race, but I’m not sure how anyone can be sure of that. The highest point on earth is easy to identify, but how can anyone be sure where the lowest point is?

Geoscopes may eventually answer that question, but by the time we can peer deep into the earth using instruments, the depth-record set by Klimchouk’s expedition – 6,825 feet deep in Krubera Super-Cave – may have been far surpassed by a subterrene, or earth-invading equivalent of a submarine. If that happens, earth-explorers will face a new problem: not cold, but heat. Rocks are still solid at 6,825 feet and we still know very little about molten depths of the earth. That’s why earthquakes are still impossible to predict. Klimchouk and Stone haven’t made great advances in geology, but they wanted to be seen as scientist-explorers, not as explorer-adventurers.

They found adventure all the same and Tabor points out that they stand in the tradition of men like Roald Amundsen, Edmund Hillary and Neil Armstrong. That tradition is coming to an end: up till now, technology has assisted minds and muscles. In future, it will re-shape them. Humans will turn into superhumans. And perhaps that will mean the end of exploration and adventure. Blind Descent may be a record of one of the last great triumphs of the old human race. If so, it’s an appropriate record: intelligent, well-written and vivid. There are some breathlessness and journalistic licence too, but Blind Descent is a good book about great feats.

Moon Observer's Guide by Peter GregoPhilip’s Moon Observer’s Guide, Peter Grego (Philip’s 2015)

If you ask someone to name the most important inventions in history, two will often be overlooked: the microscope and the telescope. You could say that one lowered the floor of the universe and the other raised the ceiling: we suddenly became aware of wonders that had previously been too small or too far away for us to see.

Practically speaking, the microscope might seem by far the more important, because it’s taught us so much about life on earth, not least our own. But the continued existence of humanity may actually depend on the telescope. Geologists have discovered that the earth has repeatedly been struck by asteroids; astronomers may be able to spot the next one before it hits. Otherwise we may follow the dinosaurs, trilobites, eurypterids and countless other once-flourishing groups into extinction.

If you want to see what asteroids and other large rocks can do to a celestial body, Mother Nature has kindly provided us with a giant memento mori: the Moon. The biggest scars there are visible with the naked eye, but it took the telescope to reveal quite what they looked like and quite how pock-marked the lunar surface is. As Peter Grego writes:

All the Moon’s ringed basins, ‘walled plains’ and the overwhelming majority of craters visible through the telescope were formed by asteroidal impact. […] Copernicus was blasted out of the lunar crust about 800 million years ago by an asteroid measuring up to 10 km across. The 29 km diameter crater Kepler, 500 km to the west of Copernicus, was formed at around the same time. (“Lunar geology and the Moon’s features”, pp. 13-4)

Grego knows a lot about the Moon and this book is the fruit of more than thirty years of selenoscopy, dating back to his first “systematic observations” in 1982:

Since that time, through patient observing and recording, the lunar landscape has become to me a broadly familiar place, yet always full of wonder. Today only a sliver of moon is visible, and the eastern lunar seas and their surrounding craters provide a visual delight until the Moon sinks into the haze above the city and its image dims, shimmers and degrades. (pg. 5)

The city was Birmingham back in 2002. Cities aren’t just noisy, dirty and harmful to wildlife. They also deprive us of one of the greatest sights in nature: the night sky. Light pollution is silent, tasteless and physically harmless, but it deserves much more attention from conservationists. The Moon can be big enough and bright enough not to be wholly drowned by it, but it’s lèse-majesté against the Queen of the Night all the same.

It also makes life much harder for amateur astronomers. Then again, perhaps that increases the rewards. And the Moon isn’t confined to the night sky, of course: you can observe it in full daylight using nothing more than binoculars. Serious observation demands a telescope, however, and Grego devotes a full section to what’s available. Inter alia, he himself has a “150mm f/8 achromatic refractor with digital camcorder setup with a zoom eyepiece for afocal video photography” (ch. 5, “Recording Your Observations”, pg. 144). Digital imaging and enhancement are now routine: modern technology can get “startling results from a seemingly mediocre video sequence” (pg. 146), sharpening and focusing blurred images.

But Grego and his fellow selenographers are still doing what Galileo, Thomas Harriot and other early astronomers did centuries ago: drawing and sketching the Moon. There’s a good practical reason to do this, as recent science-news has confirmed: “drawing pictures of information that needs to be remembered is a strong and reliable strategy to enhance memory”. There is a lot of detail to learn on the Moon. It’s a fractal place: there are craters at every scale, from the microscopic to hundreds-of-kilometres wide and “it is estimated that the Moon’s surface is studded with more than 3 trillion (3,000,000,000,000) craters larger than a metre in diameter” (pg. 9).

So learning your way around the Moon is a fractal process: first you learn to recognize the giant features, like Copernicus, Kepler and the maria (seas), montes (mountains) and valles (valleys), then you begin to fill in the gaps, then the gaps between the gaps, then the gaps between those. Grego supplies maps and commentary to help you on your way:

The polygonal crater Timaeus (33 km) perches on W. Bond’s south-western wall and surveys across the plains of Mare Frigoris across to the Montes Alpes, 175 km to the south. Archytas (32 km) and Protagoras (21) are two sharp-rimmed but somewhat misshapen craters whose dark shadow-filled eyes keep watch over the northern approaches of Mare Frigoris. (ch. 4, “Moonwatching”, Day seven, pg. 87)

He’s never finished learning about the Moon, however, and neither will anyone else. It’s a life-long adventure and although the Moon might seem cold and unchanging, at least over a human life-span, there are rare events called TLP, or “Transient Lunar Phenomena”, to look out for. These are “apparent obscurations, glows or flashes on the Moon’s surface” that don’t have definitive explanations. Are rocks collapsing? Is sublunar gas leaking out? Might there even be life there after all?

Life is highly doubtful, but Grego notes that “lunar topography is virtually neglected by professional astronomers” (pg. 6), so amateurs still have the chance to make important discoveries. This book might help someone to do that, but the rewards of selenoscopy don’t depend on advancing science or using clever technology. Grego opens the book by asking “Why Observe the Moon?”, then quotes an excellent answer to that question from the French astronomer Camille Flammarion and his book Astronomy for Amateurs (1903). What Flammarion said more than a century ago is still true today:

From all time the Moon has had the privilege of charming the gaze, and attracting the particular attention of mortals. What thoughts have not risen to her pale, yet luminous disk? Orb of mystery and of solitude, brooding over our silent nights, this celestial luminary is at once sad and splendid in her glacial purity, and her limpid rays provoke a reverie full of charm and melancholy. (“Why Observe the Moon?”, pg. 4)

In fact, you could say that the Moon is a touchstone of human nature. Chimpanzees and gorillas may be almost identical to us in their genes, but they don’t talk, make art or gaze at the Moon in wonder. We still do and although we don’t usually worship the Moon any more, we may owe it our very existence. How important have the tides been in the evolution of life on earth? They provided a zone of transition for the emergence of plants and animals from the sea, and perhaps a Moon-less Earth would also be a Man-less Earth.

But the Earth could have Moon without Man if it’s struck by an asteroid of sufficient size. The scars on the Moon’s surface should be constant reminders of the vigilance that’s necessary and the technology that we still need to develop. But the Moon is memento mori in more ways than one. Asteroid strikes are pinpricks by comparison with what may have happened to the Earth in the remote past:

Now widely accepted to be the most likely origin of the Moon is the giant impact or ‘big splash’ theory. This theory suggests that a Mars-sized planet (around half the size of the Earth) smashed into the young Earth, disintegrating the impactor and the Earth’s mantle at the site of impact. A cloud of debris was splashed into near-Earth orbit, and the outer rings of this temporary ring of material coalesced to form the Moon. (ch. 1, pg. 21)

As Sir Arthur Conan Doyle’s great character Professor Challenger pointed out in 1913: there are “many reasons why we should watch with a very close and interested attention every indication of change in those cosmic surroundings upon which our own ultimate fate may depend”. The Moon should frighten as well as awe and enchant us, or we might not survive to be awed and enchanted. This book will help you understand all these aspects of the Queen of the Night.

I also hope that Grego will write a sequel to it one day: Moon Tourist’s Guide. We’re still on schedule for at least some of the future envisaged by Arthur C. Clarke in his novel A Fall of Moondust (1961), which was set in the mid-twenty-first century. A moon-cruiser called Selene may not be sailing in a basin of dust as “fine as talcum-powder” by then, but there may still be lunar tourism. If so, selenographers like Peter Grego will be able to see close-up what they’ve long surveyed from afar.

Volcano Discoveries by Tom Pfeiffer and Ingrid SmetVolcano Discoveries: A Photographic Journey around the World, Tom Pfeiffer and Ingrid Smet (New Holland 2015)

Volcano Discoveries is a dull title for a dazzling book. I would have called it Gods of Fire instead. Mountains are naturally awe-inspiring, but ordinary ones are like slumbering or watchful gods. Volcanoes are mountain-gods that come to life, spewing fire, breathing smoke, devastating the landscape and sometimes wiping out cities. And volcanoes have been worshipped, as this book describes:

For the Mayans, in an interesting parallel to the ancient Egyptians, the pyramid was a very special shape and a holy place that connected the world with the gods. In the mountainous regions of western Guatemala, the Mayans interpreted volcanoes as natural pyramids and, unless in eruption, climbing to their summits was their way to worship them. (“Guatemala: Volcanoes of the Mayans”, pg. 153)

In Italy, the fire-god Vulcanus gave his name first to one fire-mountain, in the Aeloian archipelago, then to all of them (“Vulcano”, pg. 50). In Hawaii, Pele is the volcano-goddess, appearing either as “a tall beautiful young girl or a bent, ugly old woman” (“Hawaii”, pg. 122). Gods, goddesses and demons are everywhere in the stories told about volcanoes. That’s why Gods of Fire would have been a much better title.

But the German volcanologist Tom Pfeiffer is presumably plugging his company VolcanoDiscovery. He supplies the photographs; the Belgian geologist Ingrid Smet supplies the text. His images and her words work well together, but there’s a collaboration in the images too, like the two aspects of Pele. Some of the images are fiery and full of action, as blazing lava fountains against starry skies or pours in blood-red rivers down a slope. Others are bleak: lifeless cones, grey ash-fields, black pavements of cooled lava.

The two kinds of image contrast very effectively, as the book tours every volcanic region of the world from Iceland to Indonesia. And while some images are spectacular, some are small. The huge snow-covered cone of Shishaldin, “in the Aleutian chain”, is spectacular (pg. 141), like the vast plume of smoke belching from Fuego de Colima in Mexico (pg. 149) and the churning lava lake of Marum in the Pacific (pg. 175). Small images include ferns growing in cooled lava (pg. 139); yellow crystals of sulphur around the mouth of a “fumarolic vent” (pg. 74); and a close-up of “Pele’s hair”, or “elongated lava strings that quickly cooled down and became glass” (pg. 126).

So there’s every scale, every stage of volcanic activity, and every kind of slope, steam-plume and smoke-cloud, plus lots of facts, figures and interesting asides in the texts. If you’re interested in volcanoes, the gods of fire are waiting here. If you can raise a glass of tequila to them, even better: “whereas volcanic soils are being used throughout the world to grow grapes for wine production, in Mexico they are used for cultivation of the blue agave – the plant from which tequila is distilled” (“Mexico”, pg. 143).
