Greg Bear

Gregory Dale Bear (born August 20, 1951) is an American science fiction author. He has written about war across the galaxy, artificial universes, consciousness, and evolution.
Biography.
Bear was born in San Diego, California. From 1968 to 1973 he attended San Diego State University, where he received a Bachelor of Arts degree. In 1975, he married Christina M. Nielson, but they divorced in 1981. He remarried in 1983, to Astrid Anderson, the daughter of science fiction author Poul Anderson. They have two children, Erik and Alexandra. They live outside of Seattle, Washington.
Career.
Bear is often called a hard science fiction author because he uses many scientific details in his work.
Bear often answers major questions in contemporary science and culture with fictional solutions. For example, "The Forge of God" tries to explain the Fermi paradox. If the galaxy is filled with intelligences that could be very dangerous, young civilizations could only survive by staying quiet so nobody would notice them and attack. In "Queen of Angels" Bear examines crime, guilt and punishment in society. He does this by examining consciousness and awareness. Part of the novel is about highly advanced computers that begging to become intelligent and aware of themselves as they communicate with humans. In the two books "Darwin's Radio" and "Darwin's Children" he writes about the problem of overpopulation with a mutation the human genome making, basically a new series of humans. The books bring up the question of cultural acceptance of something brand new that cannot be stopped.
One of Bear's favorite themes is how observers effect or create reality. In "Blood Music" reality becomes unstable as the number of observers–trillions of intelligent single-cell organisms–gets higher and higher. Both "Anvil of Stars"–a sequel to "The Forge of God"–and "Moving Mars" propose a physics based on information exchange between particles, capable of being altered at the "bit level." (Bear has credited the inspiration for this idea to Frederick Kantor's 1967 treatise, "Information Mechanics.") In "Moving Mars" this knowledge is used to remove Mars from the solar system and transfer it to an orbit around a distant star.
"Blood Music" (first published as a short story in 1983, and expanded to a novel in 1985) has also been credited as being the first account of nanotechnology in science fiction. The short story described microscopic medical machines. He described DNA as a computer system that could be changed. In "Queen of Angels" and "Slant", Bear gives a detailed description of a near-future nanotechnological society. This historical sequence continues with "Heads"–which may contain the first description of a "quantum logic computer"–and with "Moving Mars". These books also show the historical development of self-awareness in AIs. One AI character called Jill is in all of these books. Bear was influenced by Robert A. Heinlein's self-aware computer Mycroft Holmes ("High-Optional, Logical, Multi-Evaluating Supervisor") in "The Moon Is a Harsh Mistress" when creating Jill.
More recent works, such as the two novels Darwin's Radio and Darwin's Children stick closely to the known facts of molecular biology of viruses and evolution. These books are about the impact of a strange disease that appears to make evolutionary transitions happen. Bear includes some very speculative ideas, but he wrote about them so carefully that "Darwin's Radio" gained praise in the science journal "Nature".
Bear, Gregory Benford, and David Brin wrote a series of three novels that take place before Isaac Asimov's famous "Foundation" series. Bear is named as the author of the second of the three books.
While most of Bear's writing is science fiction, he also wrote in other genres. Two of his early works, "The Infinity Concerto" and "The Serpent Mage"are clearly fantasies. These are now published together as one novel called "Songs of Earth and Power". "Psychlone" is horror. Bear called his story "Dead Lines" a "high-tech ghost story." He has received many accolades, including five Nebula awards and two Hugo awards for science fiction.
