Encyclopedia > Tau Zero

Tau Zero is a science fiction novel by Poul Anderson. The novel was based upon the short story "To Outlive Eternity" appearing in Galaxy Science Fiction in 1967. Science fiction is a form of speculative fiction principally dealing with the impact of imagined science and technology, or both, upon society and persons as individuals. ... Poul William Anderson (November 25, 1926 – July 31, 2001) was a prolific science fiction author of the genres Golden Age; some of his short stories were first published using the pseudonyms A. A. Craig, Michael Karageorge, and Winston P. Sanders. Poul Anderson also wrote fantasy such as the King...

The book is regarded as a quintessential example of so-called "hard" sci-fi, as its plot is guided by technology without any foray into the fantasy genre.

Tau Zero follows the crew of the starship Lenora Christine, a colonization vessel crewed by 50 men and 50 women--the first wave of the program, to be followed by additional colonists so as to firm up the settlement and avoid genetic drift. The ship is not capable of overcoming the light barrier and so is contrained by relativity, which limits it to two substantial engines, an accelerator and a decelerator. The decelerator becomes damaged during the trip, and so the ship is unable to slow down, careening helplessly towards light speed, or tau zero. Much of the book deals with the crewmembers' various reactions to the knowledge that they are being carried further and further into the future (because of the extreme time dilation caused by their ever-increasing velocity) and away from any possibility of contact with humanity. The book derives considerable power through descriptions of the changing and extreme time dilation's effects. Genetic drift is the term used in population genetics to refer to the statistical drift over time of allele frequencies in a finite population due to random sampling effects in the formation of successive generations. ...

Optimize Tau Isolation Cone Cut (1199 words)
At generation level, 1 prong tau has zero tau cone size, the truth is always: the tau's with generated 3 and 5 prong define tau cone size.
For generated 1 prong tau, want cone size to be as small as possible, the tau running track cone 5/visE with a cap 10 degree which is suggested by hadronic 3 and 5 prong generated tau's, is the best choice.
Since tau object is already isolated, so it is kind of narrow now, as it is said, isolation is about the objects outside tau object.
