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."
Cam Ranh is considered the finest deepwater shelter in Southeast Asia. North Vietnamese forces captured Cam Ranh Bay and all of its remaining facilities in 1975. Vietnam's dependence on Russia as the main source of military platforms, equipment, and armaments, has now put Hanoi in a difficult spot. Russia has pressed for special access to Cam Ranh Bay ever since it began delivering enhanced Kilo-class submarines to Vietnam. "Hanoi is invariably cautious and risk adverse in its relations with the major powers," says Carl Thayer. "The current issue of Russian tankers staging out of Cam Ranh pits Russia and China on one side and the United States on the other. There is no easy solution for Vietnam."
But for the first time in nearly half a century, that synchrony between economic growth and energy-related emissions seems to have been broken, according to the Paris-based International Energy Agency, prompting its chief economist to wonder if an important new pivot point has been reached — one that decouples economic vigor and carbon pollution. The IEA pegged carbon dioxide emissions for 2014 at 32.3 billion metric tons — essentially the same volume as 2013, even as the global economy grew at a rate of about 3 percent. Whether the disconnect is a mere fluke or a true harbinger of a paradigm shift is impossible to know. The IEA suggested that decreasing use of coal in China — and upticks in renewable electricity generation there using solar, wind and hydropower — could have contributed to the reversal.
As for the less expensive watches, perhaps they're around not so much to become a new major sales category for Apple, but rather to drive more iPhone sales. Meanwhile, the redesigned MacBook may signify a bigger change for the laptop industry than people realize: "We don’t need all those other ports, Apple says. We are living in a wireless world now, where we can connect most of our peripherals without cords." The new MacBook has also fueled speculation that Apple could be working on a more powerful tablet, something that could compete with Microsoft's Surface Pro line.
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?"
