Though difficult to make, hydrogen bombs are attractive to nations and militaries because their fuel is relatively cheap. Inside a thick metal casing, the weapon relies on a small atom bomb that works like a match to ignite the hydrogen fuel. Today, Britain, China, France, Russia and the United States are the only declared members of the thermonuclear club, each possessing hundreds or thousands of hydrogen bombs. Military experts suspect that Israel has dozens of hydrogen bombs. India, Pakistan and North Korea are seen as interested in acquiring the potent weapon. The big secret the book discusses is thermal equilibrium, the discovery that the temperature of the hydrogen fuel and the radiation could match each other during the explosion (PDF). World Scientific, a publisher in Singapore, recently made Dr. Ford's book public in electronic form, with print versions to follow. Ford remains convinced the book "contains nothing whatsoever whose dissemination could, by any stretch of the imagination, damage the United States or help a country that is trying to build a hydrogen bomb." "Were I to follow all — or even most — of your suggestions," says Ford, "it would destroy the book."
1) Mars doesn't have any life on it at all. And now, it's looking more likely that there could be bacteria living beneath the surface. 2) There would be enough of the chemical compounds we need to survive. 3) There's nothing poisonous to us on the surface. In fact, the surface is covered with perchlorates, which are highly toxic to humans, and the original Viking mission did not detect these. "It's no longer a simple matter," Robinson says. "It's possible that we could occupy, inhabit and terraform Mars. But it's probably going to take a lot longer than I described in my books."
The Golden Age science fiction publishing market was heavily geared toward magazines and short stories. And then suddenly, there was this huge demand for tons of novels. According to Andrew Liptak, this left many science fiction authors caught in a hard place: Many had come to depend on the large number of magazines on the market that would pay them for their work, and as readership declined, so too did the places in which to publish original fiction. The result was an innovative solution: repackage a number of preexisting short stories by adding to or rewriting portions of them to work together as a single story. This has its advantages; you get more narrative "payoff" with a collection of stories that also forms a single continuous meta-story than you do with a single over-arching novel — because each story has its own conclusion, and yet the story builds towards a bigger resolution. Fix-ups are a good, representative example of the transition that the publishing industry faced at the time, and how its authors adapted. Liptak says, "It's a lesson that's well-worth looking closely at, as the entire publishing industry faces new technological challenges and disruptions from the likes of self-publishing and micro-press platforms."
For example, in The Wages of Humanity, visitors from space demand the redistribution of Earth's wealth, and explain that runaway capitalism almost destroyed their civilization. In Taking Care of Gods, the hyper-advanced aliens who, billions of years ago, engineered life on Earth descend from their spaceships; they turn out to be little old men with canes and long, white beards. "We hope that you will feel a sense of filial duty towards your creators and take us in," they say. "I doubt that any Western sci-fi writer has so thoroughly explored the theme of filial piety," writes Rothman. In another story, The Devourer, a character asks, "What is civilization? Civilization is devouring, ceaselessly eating, endlessly expanding." But you can't expand forever; perhaps it would be better, another character suggests, to establish a "self-sufficient, introspective civilization." "At the core of Liu's sensibility," concludes Rothamn, "is a philosophical interest in the problem of limits. How should we react to the inherent limitations of life? Should we push against them or acquiesce?"
Her conclusion: readers tend to skim on screens, distraction is inevitable and comprehension suffers. Researchers say readers remember the location of information simply by page and text layout — that, say, the key piece of dialogue was on that page early in the book with that one long paragraph and a smudge on the corner. Researchers think this plays a key role in comprehension — something that is more difficult on screens, primarily because the time we devote to reading online is usually spent scanning and skimming, with few places (or little time) for mental markers.
Another significant problem, especially for college students, is distraction. The lives of millennials are increasingly lived on screens. In her surveys, Baron was surprised by the results to the question of whether students were more likely to multitask in hard copy (1 percent) vs. reading on-screen (90 percent). "When a digital device has an Internet connection, it's hard to resist the temptation to jump ship."
