4.0 out of 5 stars
Close and Distant Brothers, March 17, 2002
A standard illustration of the time-distorting effects predicted by Einstein's relativity equations is the traveling twin problem, where one twin remains on Earth while the other travels at near-light speed to some distant destination. Heinlein takes this textbook concept and adds two other ingredients to the mix: the twins are telepathic, and they are real people, in concocting this nice blend of great adventure and hard science.Tom and Pat are the twins in question, targeted by the Long Range Foundation as a potential communications pair on the first exploratory star-ships due to their telepathic ability to communicate over any distance at (truly) instantaneous speeds. Which one will go and which will stay forms the initial conflict of this story, and how the decision is made provides a strong base for filling in the character of each, along with some interesting psychological insights into the problems that face close siblings. While still on Earth, this section also allows Heinlein to throw in some of his typical comments about bureaucracies, government meddling, taxes, population control, and the non-democratic nature of families, all deftly folded into and directly contributing to the story line. Once the starship takes off, we find something of a more traditional adventure story, as we follow Pat on the starship and his meeting with the duties and responsibilities of ship-board life and the unforeseen hazards that the ship encounters at each of the stars it explores. In the meantime, Tom is rapidly aging on Earth, the link between the two becomes very fragile, and eventually Pat manages to establish a new telepathic link with his niece (and later his grand and great-grand niece). All necessary in order to continue the starship mission, for without being able to report the findings of the explorations, there is little point in continuing. As we move further and further out in time and space, we can see Pat grow as person, melded both by these external events and his own musings on the purpose of life and humanity, and it is this very growth that really provides the best portion of the 'entertainment'. Heinlein fully recognized that positing instantaneous communications (of any nature) was a violation of Einstein's basic theory, and rather than ignore it, he used it as a springboard to a new science that forms the basis for the ending of this book. It also allowed him to neatly finish off the story line of the two twins, but I found the ending not quite satisfying, a little too pat and quickly done (and with some gender-roles that would be considered decidedly non-politically correct today). Still, this is one of the best of his so-called 'juvenile' novels, both due to its great science and very solid characterization, couched in his typical, unforced American prose, and with enough 'meat' on its bones to engross any reader.

Telepathic twins go their separate ways - earth & the stars!, September 25, 2000
Time for the starsThis is a genuine science fiction story, where science has made something possible (interstellar travel, in this case) and the consequences on people is explored. Science fiction isn't often too thoughtful about that side of things, but this book goes some way to redressing that. It's an attractive book, one you'll want to read again. The characters are well developed and have depth, and the storyline is interesting. And here it is: the Long-range Foundation is an outfit that specialises in long range projects, surprise, surprise. And their latest venture is interstellar exploration and colonisation. But how to maintain contact? Radio is no good, since the signal from a ship which has travelled fifty light years will take fifty years to get back. But, the Long-range Foundation has discovered that twins are often telepathic, the "reception" doesn't fade with distance, and best of all, it is instantaneous! So, leave one behind, put one on the ship, and you have the perfect communication service! Or do you? Our heroes are Tom and Pat, to young twins who are tested and are discovered to be telepathic. So one goes, the other stays. The real story is ho they get on, where once they were inseparable, now they are divided by distance and time. Worse than that, the laws of relativity means that the earthbound one grows older faster - in the end, one is an old man, while the other has aged only a few years. How do they cope with a terrible wrench like that? But don't worry! This is not just a thoughtful consideration of a human problem, there's plenty of technology, alien worlds and aliens, tragedy, love even! You get to see earth society develop over fifty years or so, with all the changes that that brings about. This is a very enjoyable and readable book, and one that I would highly recommend.

5.0 out of 5 stars
Swift entertainment, February 8, 2001
This book goes to show you the different attitudes prevailing in SF compared between the fifties when this book was written and the ideas today. Today, if someone took the concept of twins being separated by relativistic effects (ie one ages faster than the other . . . go read a physics textbook for the equations) it'd be a massive complex novel detailing the cultural shock and changes, the emotional cost, and mostly have a really downer attitude about it, treating it, for the most part "realistically" whatever that's supposed to mean in science fiction. But that's now and we're talking about then. Here Heinlein takes two vastly different concepts, telepathy between twins and the travelling between the stars in ships moving at barely sub-light speeds. The focus here is on both SF adventure and what it means to leave everything you know and have not only your entire family grow old and die while you age much slower but have the whole world change (Heinlein's future slang is a gas), while you stay the same. It's a fun story, and the main character, the twin that goes, narrates his story somberly but still with a dash of zest in his voice, for all the regret he feels at being left behind, he's having a grand adventure and seeing things that no one else has ever seen. Not that it's all fun and games and a lot of things happen before the mission is over, some good and some bad. Like I said, it's a light story, you won't find anything totally deep here but it's all handled capably, as you'd imagine a master like Heinlein dealing with this . . . but please don't read it as a gender study guide and keep in mind that it was written in the fifties, when women weren't expected to do all that much. Asking permission from your husband for just about everything was the order of the day mostly . . . just don't let it bother you. Other than that, it's good solid fun, though the ending comes totally out of left field (unless I missed something), but it's a great example of the golden age of SF, when anything seemed possible. For those who want a slightly darker take on the same subject . . . go read Joe Haldeman's The Forever War and that should knock the depress-o-meter right off the scale. Still a good book though. They're both good. Read them both, now!
