Poul Anderson S Tau Zero Is An Outstanding Work Of Science Fiction, In Part Because It Combines Two Qualities That Are Often At Odds In This Genre An Interest In The Emotional Lives Of Its Characters And A Fascination With All Things Technological And Scientific In Tau Zero These Components Are Not Merely Fused They Work Together With A Remarkable Synergy That Makes The Novel Much Than Just A Deep Space Adventure StoryThe Novel Centers On A Ten Year Interstellar Voyage Aboard The Spaceship Leonora Christine, And It Opens With Members Of The Crew Preparing For Their Departure From Earth It Is An Especially Moving Departure Because They Know That While They Are Aboard The Ship And Traveling Close To The Speed Of Light, Time Will Be Passing Much Quickly Back Home As A Result, By The Time They Return Everyone They Know Will Have Long Since Died From Practically The Very First Page, Therefore, Tau Zero Sets The Scientific Realities Of Space Travel In Dramatic Tension With The No Less Real Emotional And Psychological States Of The Travelers This Is A Dynamic Anderson Explores With Great Success Over The Course Of The Novel As Fifty Crewmembers Settle In For The Long Journey Together They Are A Highly Trained Team Of Scientists And Researchers, But They Are Also A Community Of Individuals, Each Trying To Make A Life For Him Or Herself In SpaceThis Is The Background Within Which The Action Of The Novel Takes Place Anderson Carefully Depicts The Network Of Relationships Linking These People Before The Real Plot Begins To Unfold The Voyage Soon Takes An Unexpected And Disastrous Turn For The Worse The Ship Passes Through A Small, Uncharted, Cloudlike Nebula That Makes It Impossible For The Crew To Decelerate The Ship The Only Hope, In Fact, Is For The Ship To Speed Up As a novel to showcase ideas, it succeeds As a novel to showcase misogyny and thin characters in an attempt to bring real storytelling to hard SF, not so much.I ll talk of the good parts first I learned, or eventually recalled something that hadn t immediately made a connection to me right away but it should have.The word Tau has a dual meaning in the text One is Proper Time in Physics, and the other refers to coming full circle, both of which happens in the text.Reducing Tau to Zero means they re going faster and faster and faster to the theoretical maximum of speed, even to the point of traveling between galaxies within weeks They re already well and deep into the relative future by necessity of going so fast, making them realize that there s nothing left to lose because they ve left everything they ve known far behind.The end idea pushes them outside of the framework of an oscillating universe and gives them the opportunity to pick and choose from the cream of any galactic honeypot along any time because they re outside of the framework It s pretty damn cool, and even if the physics isn t accurate, the base concept that turned into the impetus of such an ambitious idea novel was striking and gorgeous It s both better and worse than Stephen Baxter s Ring, which, in hindsight, is an updated and expanded novel to do Tau Zero better than Tau Zero The Ring had a lot attention devoted to character, and although I can t say it was better, precisely, I can say that the development and progression into far time was a lot fascinating, especially with the Human Xeelee wars and the eventual grand scale exodus from this universe.Tau Zero was definitely a tighter novel, focusing on time and relative distances between stellar objects all the way to clusters of galaxies to the shifting of antimatter matter oscillations underlying the fabric of reality It was very fun to see Bussard Ramjets going far beyond their theoretical limitations, too, but I prefer Niven s treatments a LOT better Hell, I was thinking during most of this read that I preferred Neutron Star But by the end, Tau Zero pulled away from most of the similar SF pack by getting fantastical Sorry, I have a soft spot for Bigger, Kick Ass, and Mind Blowing concepts Though, in the end, I agree with the Hugo awards for 1970 This was a runner up, and Niven s Ringworld won Ringworld had Woo You can t go wrong with Woo And that leads me to the not so great in this novel It s not enough to ruin it for me, but I hated the treatment of women in it It s not much different from SO many novels of the day, granted, but this crap really grates on me It s like reading crappy sex scenes My eyes kind of glaze over and skim till the meat of the story comes back Tau Zero DID have story, too, an exploration of what it means to be cast adrift into deep time, losing their anchor to Earth and the possibility of ever meeting up with anything remotely like themselves ever again It went through despair and a great deal of military psychology and a heavy reliance on democracy committee speak rather than a strict authoritarian rulership, which makes sense if you re trying to appeal to an American public, and some of the best parts of it were the attempts to keep morale up.Unfortunately, the characters never did much for me I m SO SPOILED by modern SF and Fantasy.That being said, it was still a great idea novel So why am I reminding myself about The Number of the Beast by Heinlein Because his ideas were even better along weirdly similar lines, and a lot fantastical Possibly It s unfortunate that it also had some weird ass hangups and sophomoric fixations, too I ll never win Tau zeroPoul Anderson is a writer s writer, David Brin, Vernor Vinge and others swear by him and Vinge even dedicated his epic A Deepness in the Sky to him His influence on their work is fairly obvious, Anderson knew his science and was able to employ that knowledge to max effect in his fiction He was also a natural story teller who never neglected the human element in his sf stories.Tau Zero is I believe what veteran sf readers would call diamond hard sf where all the science in the book is based on real world science and its application in the narrative is entirely plausible So no teleportation, snarky robots, or little green men I have to admit a lot of the interstellar astronautics theory and other scientific details went whoosh right over my head, yet somehow Anderson always ensured that the story is never incomprehensible I also learned a lot about time dilation and relativity that I never knew before, which will undoubtedly make me the life of the next party I go to.The characters are fairly interesting people, led by a protagonist who is a pragmatism personified super stoic constable, but at least he is very articulate, not one of those cliche taciturn hero type In any case, given the short length of the novel 190 pages there is not all that much room to develop the characters, a lot of them seem to be defined by their personal quirks.For some reason this book reminds me of David Bowie s Space Oddity , not in specifics, as the story follows an entire starship crew not just one Major Tom However, there is a sense of thatPlanet Earth is blue and there s nothing I can dosort of loneliness and hopelessness among the crew through out most of the novel Even before the starship went out of control the crew never had any hope of returning home to the people they know due to the time dilation effect After things go pear shaped the damned thing can no longer decelerate let alone stop, heading to goodness knows where The final destination turned out to be truly awesome.A lot of people who ask for sf book recommendations in Reddit especially tend to stipulate that they don t want anything pre 70s, or even pre 80s due to the misconception that old sf books are outdated Their prerogative of course but it is a shame that they will miss out on older gems like this one.Now go take your protein pills and put your helmet on. If you re into stuff like this, you can read the full review.SFional Lorentz Transformations Tau Zero by Poul Anderson Consider a single light year is an inconceivable abyss Denumerable but inconceivable At an ordinary speed say, a reasonable pace for a car in megalopolitan traffic, two kilometers per minute you would consume almost nine million years in crossing it And in Sol s neighborhood, the stars averaged some nine light years part Beta Virginis was thirty two distant Nevertheless, such spaces could be conquered In Tau Zero by Poul Anderson.Yeah I m aware of the twin paradox and how Special Relativity alone doesn t account for the returning twin being younger at the time I remember wondering specifically whether one of the main criticism of Tau zero i.e that the crew of the ship should observe the universe as being slower relative to them while they re accelerating, not sped up as it is in the book was on the nose Not that most people think that special relativity is simple, but in fact it is even trickier than is apparent the first time you meet it. faster, faster, faster to the future or to deathfascinating ideas less than fascinating execution characters are often tedious, yet still manage to be surprisingly real and at times even moving overall dry, thoughtful, mournful, mind boggling a word that i probably use too frequently when writing about sci fi and, in the end, rather uplifting that said, this is sadly a somewhat forgettable experience and i just read it this year i think for something to really pop for me, i need the intricacy of ideas to be paralleled, to some extent, with depth of characterization and or complexity of narrative perhaps this is my bad. I m reading this book as moderator of a discussion on Sci Fi Aficionadoes this month No one has chimed in yet on the discussion It s a little lonely The reason I m bringing that up is because Tau Zero was the winner of our Time Travel theme, which has me a little bitbefuddled I mean, yes, they travel through time, but in the same direction as the rest of us At near light speed, so, you know, faster, or slower, or whatever But in one direction I guess that s time travel, but by that logic, every book that is in any way linear is about time travel.Note The rest of this review has been withdrawn due to the changes in Goodreads policy and enforcement You can read why I came to this decision here.In the meantime, you can read the entire review at Smorgasbook Poul Anderson doesn t understand Special Relativity very well an interstellar ramscoop spaceship can t carry on accelerating indefinitely, for all sorts of reasons His understanding of General Relativity is even worse Even if the Universe is cyclical, whatever would it mean to be outside the monobloc during the Big Crunch You d be outside the Universe.Well an SF writer s normal solution to problems like these is to add some sex and violence, and it works here too Sort of. According to James Blish, Tau Zero is the ultimate hard science fiction novel.For readers with a background in physics and math, there s certainly generous helping of science, for example Precisely because there is an absolute limiting speed at which light travels in vacuo likewise neutrinos there is an interdependence of space, time, matter, and energy The tau factor enters the equations If v is the uniform velocity of a spaceship, and c the velocity of light, then tau equals here the author provides the mathematical equation The closer that v comes to c, the closer tau comes to zero For non science types like myself, there s enough conceptual framework to understand what s going on with a rocket ship moving through space Two key points 1 traveling close to the speed of light, time bends So the universe and the people back on earth can age 100 years while the crew in the ship only age, say, 1 month 2 when the crew on board encounters an unexpected force field, the ship incurs damage, propelling it to move at greater and greater acceleration with no possibility of a return trip to earth.This is exactly what happens to the Leonora Christine and its crew of 25 men and 25 women on its mission to colonize a distant planet beyond our solar system If you can click into Poul Anderson s sf vision, Tau Zero makes for an exciting outer space adventure Here s some mostly non science stuff readers can look forward to ALL NATIONS UNITEDIn this future world, Sweden is the leading global power The crew is made up of a rainbow of nationalities, a true international crowd from countries such as Sweden, China, Russia, US, Germany, even a captain from Antarctica, And each of the 50 women and men aboard have expertise within the fields of science and technology ARTThose who have talent in the arts are provided with ample opportunity to express themselves Reymont the captain watches as molecular biologist Emma Glassgold sketches out a mural that will eventually be filled with forests and lakes Additionally, the rocket builders back on earth had the foresight to include aesthetic considerations all of the residential and recreational decks its a huge rocket ship, the size of a skyscraper are covered with a green material that s as springy as grass.GAMESThe crew can keep themselves in top shape by swimming in the pool or playing vigorous games like handball where, at low gee, players can virtually walk up the walls, making for spectacular play I bet it does I d like to see a film of handball played at low gravity NUDITY AND SEXWell beyond the 21st century, these fit, youthful women and men have little social inhibition about undressing and being in the nude Same goes for sex at least for starters MORALS AND RELATIONSHIPS I want a decent marriage, Glassgold said with a flick of anger, and as many children as God gives me But they will know who their father is It doesn t hurt if I don t play any ridiculous game of musical beds while we travel We have enough girls aboard who do Over time, relationships are formed and fidelity is expected In this way Poul Anderson presents two overarching dramas the scientific challenges encounters, especially the disruption in plans caused by the force field, and the unfolding dramas of romance and relationships among the men and women Keep in mind they are together in the Leonora Christine for years with the prospect of years to come After awhile, even a giant rocket ship can feel claustrophobic DISCOVERYAstronomers take this unique space travel opportunity to gather critical details about the universe heretofore unavailable gamma ray spectra among others Yet again an additional dimension of the novel appealing for those interested in the sciences DREAM AND HALLUCINATION There s an apparatus on board where one lies down, relaxes, and is hooked up to circuitry producing electronic stimulation to the brain to induce extraordinarily intense and lengthy dreams and hallucinations This practice is a way to effectively deal with the sensory deprivation as a consequence of years confined within a ship Thus, in this manner, many of the crew are able to retain their sanity I might add here there are no direct references in the novel regarding drugs quite a development recognizing the widespread use of a vast variety of drugs, both legal and illegal, currently very much part of daily life in countries like the US HUMAN NATUREMany are the reflections on human nature and humankind s place in the universe At one point, a crew member shares this thought A shipful of witches, devils, vampires, goblins, bogles, and spooks screaming their way down the sky toward the Black Sabbath Well, aren t we That s one way of looking at it however, I don t think I m giving away too much by saying Poul Anderson enjoys his sf stories complete with a number of space heroes Pick up a copy of Tau Zero and read all about it.American science Fiction author Poul Anderson, 1926 2001 Who can we trust with a monopoly of the planet killer weapons and unlimited powers of inspection and arrest Why, a country big and modern enough to make peace keeping a major industry but not big enough to conquer anyone else or force its will on anyone without the support of a majority of nations and reasonably well thought of by everyone In short, Sweden Poul Anderson, Tau Zero This CLASSY SF CLASSIC concernimg a cadre of colonists setting sail to colonize a compatible star using an interstellar Bussard Ramjet is a superior sample of Hard science fiction For those of you unsciencey non nerdy types who are unfamilar with what a Bussard Ramjet is, I have put together the following DETAILED explanation which should explain everything.make sense..great My overall rating is really based on balancing what I thought were some mind wrecking and very well described science fiction concepts with some pretty weak bordering on dull characters that prevented me from ever being truly drawn into the narrative tension of the plot I figured I would just lay out the good and the bad and let you take from it what you will.THE GOOD Poul Anderson does a phenomenal job of introducing and describing some REALLY, REALLY BIG IDEAS, mostly centering around relativity and the effect of high rates of speed on the subjective passage of time Two things I want to praise Poul Anderson for at the outset are 1 his knack for explaining clearly and understandably the scientific concepts surrounding relativity without bogging down the story and 2 proving that you can do hard SF in under 200 pages and still make the story feel EPIC in scope The basic plot concerns a prototype starship called the Leonora Christine that employs a Bussard ramjet and is intended to transport a crew of 50 colonists to a distant star system in the hopes of setting up a new colony I was curious about what a Bussard ramjet might look like and found the following picture that I thought I would share NERDY NOTE The red gas in the front is the hydrogen being collected from space that then gets compressed to the point where nuclear fusion occurs and creates the energy for propulsion that you see represented in the rear. So this propulsion system allows for travel at a high percentage of the speed of light which, as a result of special relativity, causes time dilation for the crew This means that while the crew will spend about 5 years on the journey, about 33 years will have passed on Earth.at this point if you have any LSD, it might be a good idea to take some Given the speeds that the ship travels at it takes a very long time to both accelerate and decelerate In fact, it is intended that the first 2.5 years of the journey will be spent speeding up and the last 2.5 years will be spent slowing down.I don t want to give away any spoilers so I will just say that things get very interesting and Poul Anderson takes the reader on an epic journey across time and space Big stuff, interesting stuff and very cool stuff For this aspect of the story 4.5 to 5.0 stars THE BAD The bad can really be summed up pretty easily The characters are weak, two dimensional and you never care enough about them to be sucked into the story when problems arise You have your crew from different backgrounds with various quirks and issues, none of which are very interesting or compelling However, since the book is less than 200 pages long I am willing to be forgiving than I would be if this was longer and I was forced to spend time with the crew in order to get to the good parts Plus, this really is an idea book and so I understand the characters being little than filler Still, they could have been done much better and so I give this aspect of the story 2.0 stars and a well deserved FACEPALM OVERALLOverall, I gave this 3.5 to 4.0 stars because I thought the awesomeness of the SF ideas than compensated for the weak characters, especially given how the book is under 200 pages Definitely worthy of the title classic and one I Highly Recommend Nominee Hugo Award for Best Science Fiction Novel 1971 Nominee Locus Award for Best Science Fiction Novel Four and half star for the idea of the book I imagine I would gave solid five star without second thought if I read Tau Zero when I had just started reading science fiction.The ending was perfect for me surprising although could be predictable Like good mystery novels, the ending of this book was not cheating the readers.I admit, if I seek a perfect read, this book is still not perfect The characters are mostly flat and the plot is or less predictable But how could you filled such a thin novel with many round characters The characters were squeezed into thin flat ones, reacting to the plot.
