What is time, and what is the right language to describe change, in a closed system like the universe, which contains all of its observers?

January 21, 2002 by Lee Smolin

Since the observers are inside the universe itself, we must formulate a “background-independent” quantum theory of gravity and cosmology , as well as the notions of time and change, to apply to a system with no fixed background, which contains all its possible observers–perhaps even one in which the laws themselves evolve as the universe does. Lee Smolin responds to Edge publisher/editor John Brockman’s request to futurists to pose “hard-edge” questions that “render visible the deeper meanings of our lives, redefine who and what we are.”… read more

Clottocytes: Artificial Mechanical Platelets

April 12, 2002 by Robert A. Freitas Jr.

Nanorobotic artificial mechanical platelets (“clottocytes”) may allow for complete hemostasis in as little as one second – 100 to 1000 times faster than the natural system and 10,000 times more effective in terms of bloodstream concentration. They could also work internally. Using acoustic pulses, a blood vessel break could be rapidly communicated to neighboring clottocytes, immediately triggering a progressive controlled mesh-release cascade.… read more

Deep Fritz Draws: Are Humans Getting Smarter, or Are Computers Getting Stupider?

October 20, 2002 by Ray Kurzweil

The Deep Fritz computer chess software only achieved a draw in its recent chess tournament with Vladimir Kramnik because it has available only about 1.3% as much brute force computation as the earlier Deep Blue’s specialized hardware. Despite that, it plays chess at about the same level because of its superior pattern recognition-based pruning algorithm. In six years, a program like Deep Fritz will again achieve Deep Blue’s ability to analyze 200 million board positions per second. Deep Fritz-like chess programs running on ordinary personal computers will routinely defeat all humans later in this decade.… read more

Parallel universes, the Matrix, and superintelligence

June 26, 2003 by Michio Kaku

Physicists are converging on a “theory of everything,” probing the 11th dimension, developing computers for the next generation of robots, and speculating about civilizations millions of years ahead of ours, says Dr. Michio Kaku, author of the best-sellers Hyperspace and Visions and co-founder of String Field Theory, in this interview by Editor Amara D. Angelica.… read more

What the Future Will Bring

June 15, 2005 by Ray Kurzweil

“Follow your passion,” Ray Kurzweil advised graduates in a commencement address on May 21 at Worcester Polytechnic Institute, one of the nation’s earliest technological universities. “Creating knowledge is what will be most exciting in life. To create knowledge you have to have passion, so find a challenge that you can be passionate about and you can find the ideas to overcome that challenge.” Kurzweil also described the three great coming revolutions-genetics, nanotechnology and robotics-and their implications for our lives ahead.… read more
