 The Supercollider Was an Unreasonable Gamble`

Now particle physics in the United States is struggling to survive the d isaster of the Supercond ucting Supercollid er. The Supercollid er was a gigantic particle accelerator project that was canceled in 1 993 after about 3 billion d ollars had alread y been spent on it. The cancellation was a personal traged y for many of my friend s who had d evoted the best years of their lives to the project. But when I speak of the d isaster of the Supercond ucting Supercollid er, I d o not mean the can...

 AI View of AI, Scaling Wars

The artilects, as they have been conceived so far in this book, have been largely "nanoteched" creatures. But nanotechnology may be unnecessarily restrictive and far too large a scale to be suitable for advanced artilects. It may be possible that a "femtoteched" creature could be built. Such "femto-artilects" or "femtolects" as they will be called from now on, would be vastly superior to "nano-artilects" or "nanolects," thus setting the stage for a new "species dominance war" all over again. ...

 Life Favors a Cold, Expanding Universe

If, on the other hand, we live in an open universe, infinite in space and time and continuing to expand into a future without end, then life has to face a prospect of slow freezing {111} rather than quick frying. The universe grows constantly colder as it expands, and the supply of free energy is constantly dwindling. To many people this future of endless ice has seemed even more dismal than the future of cataclysmic fire. But the laws of cosmic ecology put these futures into a very differe...

In programmable matter, the same cubic meter of machinery can become a wind tunnel at one moment, a polymer soup at the next; it can model a sea of fermions [elementary particles], a genetic pool, or an epidemiology experiment at the flick of a console key. Ten times as large a simulation will simply require ten cubic meters of machinery, instead of one. Flexibility, instant reconfigurability, variable resolution, total accessibility, and handling safety make such programmable matter worth a ...
