Silverhair

Audiences around the world have been enchanted by James Cameron’s visionary , with its glimpse of the Na’vi on the marvelous world of Pandora. But the movie is not entirely a fantasy; there is a scientific rationale for much of what we saw on the screen, from the possibility of travel to other worlds, to the life forms seen on screen and the ecological and cybernetic concepts that underpin the ‘neural networks’ in which the Na’vi and their sacred trees are joined, as well as to the mind-linking to the avatars themselves.

From popular science journalist and acclaimed science fiction author Stephen Baxter, THE SCIENCE OF AVATAR is a guide to the rigorous fact behind the fiction. It will enhance the readers’ enjoyment of the movie experience by drawing them further into its imagined world.

Meticulously researched, simply told and appropriate for readers of all ages, this second volume (after 1999’s ) in Baxter’s trilogy brings to compelling life the complex culture of these giant creatures. It’s sixteen thousand years B.C., and woolly mammoths roam the earth, inhabiting the steppes of Beringia, the land bridge linking Asia and North America. Climactic changes have caused the steppes to recede, but humans, whom the mammoths call Fireheads, pose the greatest threat to their survival. Longtusk, whose coming-of-age story this is, must save the mammoths by spearheading an epic journey. Separated from his family, Longtusk is enslaved by the Fireheads, who make him a beast of burden. But a Dreamer (Neanderthal) woman foretells his future: Longtusk will die, along with the Dreamer who once saved his life and that of the Firehead matriarch, Crocus. Although Longtusk escapes his captors and finds a steppe that will support a small mammoth herd, years later Crocus and her people return, seeking to drive the mammoths away from their habitat. Longtusk embarks on a final heroic mission to save the mammoths and meet his fate. The book’s themes of ecological disaster, warfare and change resonate deeply with today’s concerns. When a mastodont tells Longtusk, "You and I must take the world as it is. [The Fireheads] imagined how it might be different. Whether it’s better is beside the point; to the Fireheads, change is all that matters," it’s clear that humans have not changed at all.

Transported to the Sky Steppe of Mars in the final, satisfying book in British author Baxter’s highly original Mammoth trilogy (), his engaging wooly characters face an abandoned and potentially lethal terraforming experiment left there by humans (aka “the Lost”). Matriarch mammoth Silverhair’s daughter, Icebones, awakens from an unnatural slumber to find herself in a land and time far from her native Pleistocene earth. The mammoths here have no knowledge of their ancient culture, such as the teachings of their mighty progenitor, Kilukpuk. Mammoth tradition says the Sky Steppe is “the Island in the sky where... mammoths would one day find a world of their own, free from the predations and cruelty of the Lost, a world of calm and plenty” yet whatever promise Mars once held is fading now as the changes made by human engineers are reversed under the assault of the red planet’s uncompromising weather and geology. Icebones’s companions, used to depending on the Lost for everything, can’t possibly survive alone. Their only hope is to cross half the world to reach the Footfall of Kilukpuk, a rich valley full of all the sweet grass and water the mammoths need. The journey is long and treacherous, but as the beasts’ great Cycle says, “The mammoth dies, but mammoths live on.” Baxter fills the tale with taut adventure and splendid settings, making it easy to suspend disbelief.

Time^st

The book begins at the end of space and time, when the last descendants of humanity face an infinite but pointless existence. Due to proton decay the physical universe has collapsed, but some form of intelligence has survived by embedding itself into a lossless computing substrate where it can theoretically survive indefinitely. However, since there will never be new input, eventually all possible thoughts will be exhausted. Some portion of this intelligence decides that this should not have been the ultimate fate of the universe, and takes action to change the past, centering around the early 21 century. The changes come in several forms, including a message to Reid Malenfant, the appearance of super-intelligent children around the world, and the discovery of a mysterious gateway on asteroid 3753 Cruithne.

First there were good times: humankind reached glorious heights, even immortality. Then there were bad times: Earth was occupied by the faceless, brutal Qax. Immortality drugs were confiscated, the human spirit crushed. Earth became a vast factory for alien foodstuffs.

Into this new dark age appears the end of a tunnel through time. Made from exotic matter, it is humanity’s greatest engineering project in the pre-Qax era, where the other end of the tunnel remains anchored near Jupiter. When a small group of humans in a makeshift craft outwit the Qax to escape to the past through the tunnel, it is not to warn the people of Earth against the Qax, who are sure to follow them. For these men and women from the future are themselves dangerous fanatics in pursuit of their own bizarre quantum grail.

Michael Poole, architect of the tunnel, must boldly confront the consequences of his genius.

The crowning achievement of any professional writer is to get paid twice for the same material: write a piece for one publisher and then tweak it just enough that you can turn around and sell it to someone else. While it’s specious to accuse Stephen Baxter and Arthur C. Clarke of this, fans of both authors will definitely notice some striking similarities between and other recent works by the two, specifically Baxter’s and Clarke’s .

The Light of Other Days

For Baxter’s part, the develops another aspect of ’s notion that humanity might have to master the flow of time itself to avert a comparatively mundane disaster (yet another yawn-inducing big rock threatening to hit the earth); Clarke, just as he did with ’s anti-gun ray, speculates on how a revolutionary technology can change the world forever.

Ironically, you’ll probably appreciate most after you’ve put it down. The prolific and acclaimed Stephen Baxter has always been praised for his imaginative and conscientious use of science, and is no exception. This collection of short stories will leave you ruminating for days over the sprawl of ideas, worlds, and life forms Baxter has woven together.

Filling in the gaps on Baxter’s ambitious, almost audacious, 10-million-year timeline called the “Xeelee Sequence,” is a collection of revised, previously published short stories that bridges together his popular novels set in this same “future history” — , , , and . Baxter’s universe is rotten with life, from strange tree-stump-like creatures with superfluid ice skeletons to dark matter “birds” to sentient beings composed of pure mathematics. And Baxter’s reverence for life’s beauty, for its voracious robustness, is hard to resist — especially when it comes to humanity and its tentative, eager rise. The cycling timeline follows humans as they come into their own as a star-faring race, from their first sporadic steps to their near dominance of the universe and beyond.

A race of microscopic beings, who were genetically engineered to survive on the turbulent mantle of a neutron star and who vividly remember their superbeing creators, prepare for the biggest family reunion in history.

Baxter connects the lives of George Poole in the present and Regina at the end of the Roman empire. George’s father has just died, and the picture of a girl, Rosa, comes to light in his effects. Rosa is the mysterious twin George never knew, and he becomes consumed with the desire to find her. Regina’s part of the story begins in Britain at the end of Roman rule and takes her through the western empire’s collapse to Rome itself. Back to the near-past: George’s sister, it develops, had been sent to the Order of Mary, Queen of Virgins, which has existed, hive-like, in Rome since the time of Regina, one of its founders. George is Regina’s descendant, and the order being rather a family affair, George arrives at many uncomfortable realizations as he learns more about it. Opening with an artificial anomaly discovered in the Kuiper Belt beyond Neptune and ending with disturbing extrapolation of humanity’s future, is a fabric of many slowly developed plot threads woven into a tight tapestry.

In humankind’s Third Expansion, the species has spread throughout the galaxy and assimilated all challengers but the mysterious Xeelee; in a 20,000-year stalemate, humans have kept them at bay in the galaxy’s center. Time travel (used by both sides to gather intelligence) creates numerous “drafts” of time lines, but apart from this uncertainty the endless war has brought about a strangely static human society. Soldiers and pilots are bred in vats near the Front and taught only war; few survive past their teens. When Prius, a young pilot, captures a Xeelee ship and takes it to the recent past for study, an innovative program is begun to develop new weapons technology. While Prius Blue (the pilot from the future time line, now stuck in this one) is sent to the Front, the younger Prius Red (from this time line) must travel throughout the solar system with an eccentric but brilliant scientist in a quest for knowledge needed for the anti-Xeelee weapon. Working with widely differing elements of society, Red learns many secrets he’d rather not know, adjusts to new knowledge, and grows into a leadership role: he heads up Exultant, the elite squadron tasked with deploying the new weapon. Even in a genre characterized by unfettered imagination, Baxter’s future universe is extraordinary in its depth, breadth, and richness of invention. Cutting-edge physics, subtle humor, time-travel paradoxes, and loopy twists combine to give readers a wonderfully original sci-fi experience. It can be read independently of , which is set in the same universe but mostly in the present age.
