The Power of Illusion


Book Description

A new collection of stories by the master of humorous science fiction adventure, including: The full-length novel, The Day the Machines Stopped¾and what happens, not just to civilization, but to humanity and its chances of survival when all the machines stop working at once? A man is captured by aliens who are investigating the Earth as a possible target for colonization. The aliens have science and technology far in advance of humans¾but, unfortunately for them, they have never developed the human art of bluffing. For the first time in book form, Anvil's stories of Richard Verner, who is called in to solve apparently insoluble problems, such as explaining why experimental missiles keep failing for no apparent reason, or locating a kidnapped judge, or even solving an inexplicable murder that's interrupting his vacation. And much more, in a generous volume of sardonically humorous science fiction. At the publisher's request, this title is sold without DRM (Digital Rights Management).

The Trouble With Humans


Book Description

Humans¾there's no understanding them, And no dealing with them either. Or even their planet. Pity the poor aliens, whose shape-changing ability should let them take over the planet Earth before the humans even know they're there-if it weren't for all that omnipresent pollution. Or consider another set of invaders, from a planet where the weather is always mild and the changing of the seasons is hardly noticeable. They land in force and their weapons are more powerful than those of the primitive humans-but they've never before had to deal with below-zero temperatures, flash floods or tornados-not to mention volcanoes. Then there were the aliens who noticed how belligerent humans were, and gave them the "gift" of TV-like devices which would show anything anywhere on Earth, which was sure to lead to war. Imagine how surprised the aliens were when the humans took the gadgets apart, improved them, and started spying on everything the aliens were up to, all over the galaxy. Humans don't make sense, they don't fight fair, and they're making aliens throughout interstellar space think seriously about pulling up stakes and moving to another galaxy!

Dynamic fracture


Book Description

From time to time the International Journal of Fracture has presented matters thought to be of special interest to its readers. In previous special issues (December 1980 and April 1981), Dr H.W. Liu as Guest Editor presented a series of review papers dealing with fatigue processes and characteristics in metals and non-metals. Continuing this policy, which is consistent with our stated objectives, a second review dealing with time depen dence in the fracture process, including the effect of material inertia but essentially excluding very strong shock effects in solids, has been assembled under the generic term "dynamic fracture". We hope that the ensuing state-of-the-art review will yield an instructive and timely product which readers will find useful. To assist us in presenting this subject, we have prevailed upon a well-known worker in dynamic fracture, Dr W.G. Knauss, Professor of Aeronautics and Applied Mechanics, California Institute of Technology to act as Guest Editor for this special double issue. On behalf of the editors and publisher, I wish to express our indebtedness to Professor Knauss and his invited authors for undertaking this special effort.
