The Worlds of Robert A. Heinlein is a collection of science fiction short stories by Robert A. Heinlein published in 1966. It includes an introduction entitled "Pandora's Box" that describes some of the difficulties in making predictions about the near future.

The prediction was originally published in Galaxy magazine, Feb 1952, Vol. 3, No. 5, under the title "Where to?" (pp. 13-22). Following the introduction are five short * "Free Men" (written c. 1947, but first published in this collection, 1966) * "Blowups Happen" (1940) * "Searchlight" (1962) * "Life-Line" (1939) * "Solution Unsatisfactory" (1940) In 1980, the entire contents of this collection, including "Pandora's Box" (further updated), were engulfed in Heinlein's collection, Expanded Universe.

Robert Anson Heinlein was an American science fiction author, aeronautical engineer, and naval officer. Sometimes called the "dean of science fiction writers", he was among the first to emphasize scientific accuracy in his fiction, and was thus a pioneer of the subgenre of hard science fiction. His published works, both fiction and non-fiction, express admiration for competence and emphasize the value of critical thinking. His plots often posed provocative situations which challenged conventional social mores. His work continues to have an influence on the science-fiction genre, and on modern culture more generally.
Heinlein became one of the first American science-fiction writers to break into mainstream magazines such as The Saturday Evening Post in the late 1940s. He was one of the best-selling science-fiction novelists for many decades, and he, Isaac Asimov, and Arthur C. Clarke are often considered the "Big Three" of English-language science fiction authors. Notable Heinlein works include Stranger in a Strange Land, Starship Troopers (which helped mold the space marine and mecha archetypes) and The Moon Is a Harsh Mistress. His work sometimes had controversial aspects, such as plural marriage in The Moon Is a Harsh Mistress, militarism in Starship Troopers and technologically competent women characters who were formidable, yet often stereotypically feminine—such as Friday.
Heinlein used his science fiction as a way to explore provocative social and political ideas and to speculate how progress in science and engineering might shape the future of politics, race, religion, and sex. Within the framework of his science-fiction stories, Heinlein repeatedly addressed certain social themes: the importance of individual liberty and self-reliance, the nature of sexual relationships, the obligation individuals owe to their societies, the influence of organized religion on culture and government, and the tendency of society to repress nonconformist thought. He also speculated on the influence of space travel on human cultural practices.
Heinlein was named the first Science Fiction Writers Grand Master in 1974. Four of his novels won Hugo Awards. In addition, fifty years after publication, seven of his works were awarded "Retro Hugos"—awards given retrospectively for works that were published before the Hugo Awards came into existence. In his fiction, Heinlein coined terms that have become part of the English language, including grok, waldo and speculative fiction, as well as popularizing existing terms like "TANSTAAFL", "pay it forward", and "space marine". He also anticipated mechanical computer-aided design with "Drafting Dan" and described a modern version of a waterbed in his novel Beyond This Horizon.
Also wrote under Pen names: Anson McDonald, Lyle Monroe, Caleb Saunders, John Riverside and Simon York.

An interesting, and sometimes entertaining, look into early Heinlein via some short stories.
-Pandora's Box discusses some of Heinlein's earlier predictions and how they failed or came true (most failed). Then he goes on (in footnotes at the end of the piece) to make updated predictions, most of which didn't come true or failed miserably. However, it works into his premise that science fiction writers aren't accurate predictors of the future, but rather entertainers who invent their own future.
-Free Men. A world where there is a repressive government. His main characters are part of the resistance movement. Inspiring to an extent.
-Blowups Happen. People caring for a "big bomb" that supplies power for a large part of the company. It's always on the verge of blowing up. Written early in WWII before nuclear power was harnessed. It's mostly about the psychological problems faced by people who are constantly nursing such a monster where a good portion of humanity will die if they mess up.
-Searchlight. A blind girl is lost on the moon and a unique solution for finding her.
-Life-Line. The "doctor" can predict a person's time of death. The Life Insurance companies are not thrilled. Interesting study in greed and "expert" blindness.
-Solution Unsatisfactory. Another WWII book that misses the atomic bomb, but comes up with another military use for radioactive material. As usual, it comes down to people and how they react to a doomsday weapon.

Heinlein always writes about people (which is the best way to make a story interesting). Science fiction that features "gee whiz" stuff always falls short of being interesting. That's why he's "the Dean".

Actually, this is a fast reread of a book I first read in the 60s. One outstanding story is "Solution Unsatisfactory" from 1940. Found it disturbing then and still find it powerful. Perhaps RAH's best short story.

Though it would be easy to dismiss this book, on first glance, as just another old collection of even older pulp-era science fiction stories, it's actually much more than that. These are early Heinlein stories, and not necessarily what I would cal his "best" work, but I found a couple of the stories in particular strangely disturbing. The highpoint, still, is the opening essay "Pandora's Box" in which Heinlein tackles the question of the SF author's ability to or intention to accurately predict the future. If you can find a copy of this book, read it for yourself while I'm off writing a more in depth look at it, but buckle up--you're in for a bumpy flight on a number of discrete levels.

This short collection of four stories and an easy is primarily concerned with the dangers of atomic weaponry.

Unfortunately this collection commits the cardinal sin of having good ideas handled in a deathly dull way.

Antique Sci-Fi...This book of various Heinlein short stories was printed in about '66. In his 1939 story, 'Solution Unsatisfactory', it's interesting to see Heinlein predict how America will get involved in World War II and how they'll use Atomic Energy. His other stories in this collection are also a chapter out of the history of Science Fiction. Saved from the recycle bin at Earthworks.

A set of short stories that are collectively, a bit hit and miss - I liked some, sorta skimmed the thers. That aside, you could say that Heinlein was a visionary, lots of the things he wrote about here would eventually come true in one way or another.

Worlds of Robert A. Heinlein is a nice little short story collection, though a bit inconsistent. These are reprints of some of his stories from the pulps, and he includes a short dissertation on the nature of science fiction, writing, and the future in his introduction, called Pandora's Box. I can see some of the roots of what I consider to be the essential elements of good writing described here - I always thought I'd come up with them on my own. Ah well. In this essay, Heinlein gives some of his predictions for what the future will be like in 50 years, and he was writing in 1966, so at this point one can tell how well he did as a prognosticator.


Interplanetary travel is waiting at your front door. Nowhere even close.
Contraception and control of disease is revising relations between sexes to an extent that will change our entire social and economic structure. Nailed it.
The most important military fact of this century is that there is no way to repel an attack from outer space. See #1.
It is utterly impossible that the United States will start a "preventive war." ROFL.
...the housing shortage will be solved...Still with us.
We'll all be getting hungry by and by. We'll all be getting obese, more likely in the U.S.
The cult of the phony in art will disappear. What an impossible dream.
...psychoanalysis will be replaced by 'operational psychology' based on measurement and prediction. Naw.
Cancer, the common cold, and tooth decay will all be conquered. Unfortunately, no.
...mankind will have explored the solar system, and the first ship to reach the nearest star will be abuilding. Sadly, our spacefaring days may be over.
Your personal telephone will be small enough to carry in your handbag. Wow! He had no idea.
He lists a few more, but nothing of consequence.

The first story, Free Men, is about the resistance movement in the U.S. after invasion by an undescribed foreign power. It ends abruptly and inconclusively, as if perhaps there was a larger story in mind never got around to penning. The only thing recognizable is the quote "You can't enslave a free man, the most you can do is kill him."

Blowups Happen is the story of how scientists deal with the difficult problem of keeping an atomic power plant running, when it could turn into an atomic bomb at any time, and when the entire economy of our nation depends on its continued operation. A little technical, yet hokey.

Searchlight is a cute short short about locating and rescuing a little girl - a piano prodigy - when her ship crashes on the Moon, using music.

Life-Line is the story of how Dr. Hugo Pinero discovers a scientific method to determine the date and hour of a man's death. This understandably upsets the life insurance companies, and begins a legal battle to prohibit him from doing business. Heinlein has some interesting things to say about the scientific method.

Solution Unsatisfactory might be regarded as an allegory, of sorts. It's a story in an alternate history, where the atomic bomb was never invented, and the path to a super weapon went a different direction, creating a radioactive dust which kills wholesale, and against which there is no effective defense. Some of this is about the "road not taken" by the U.S. after WWII, when we dropped the atomic bomb, but failed to anticipate the future proliferation of nuclear weapons, and the danger which they now pose when acquired by rogue states. Very thought provoking.

As I said, a bit inconsistent, but still a good read.

At least two of these were written just before World War II; at least one, “Blowups Happen”, was slightly edited “but not rewritten” to get the terminology of World War II correct, by “inserting words such as ‘Manhattan Project’ and ‘Hiroshima’”.

Except for “Solution Unsatisfactory” they’re all reprints; “Solution Unsatisfactory” was written pre-war, possibly just barely (“twenty-five years… since I wrote that story”), but was never published. It’s extremely interesting because Heinlein identifies several of the problems inherent in the United States introducing and using nuclear weapons, while going off in a completely different direction.

One of the most interesting aspects of this story is his treatment—or lack thereof—of President Roosevelt. It appears that his Roosevelt never ran for a third term; His President’s record included a term as Mayor (city unspecified) and then as Senator. Heinlein’s United States politicians honor their commitment to not enter the war, and limit themselves to providing aid to Great Britain.

This may have been merely an attempt at getting fictional characters into the leadership of the various nations; neither Stalin nor Hitler are around by the time the leaders of their countries enter the story. I’m not sure he saw Churchill in a leadership position at all.

On the other hand, he does identify the two poles of the post-nuclear world to be the United States and the Soviets, with the Soviets (if I’m reading it right—he calls them the Eurasian Union, but their leader was still Stalin) the second country to discover the secret.

He does not predict the strategy of Mutually Assured Destruction, although that’s possibly because his ultimate weapon is far easier to make than a nuclear bomb. Given a supply of uranium, it could be made in garage laboratories, not just by governments. But he also, somewhat surprisingly, doesn’t see the intercontinental ballistic missile.

I’m not sure he edited this story; he does use the term “World War II” but that was already a known term even before the start of the war overseas.

Among the other reprints, “Pandora’s Box” is interesting because it’s his predictions from about 1952, with his notes from the 1966 publication of this book. He’s very optimistic about interplanetary travel and life on other planets; he still clings to Malthusian predictions of hunger while recognizing that they seem to be late in coming. But “communism will vanish from the planet”, which is both very optimistic and, especially to the extent he was writing mostly about the Soviet Union, against the received wisdom of his time.

Other than that, two of the stories are interesting problem-solving vignettes: how to use atomic power for generating electricity safely; how to find someone lost on the moon. One is barely a story, about a revolutionary cell in post-tyranny America, and the other is an anti-adventure story about a physicist who discovers how to accurately predict any living being’s time and date of death, and what happens to the insurance industry.

An intriguing look into the mind of one of the legends of sci-fi writing.
This collection of short tales starts with 'Pandora's Box', possibly the most interesting piece in the book. It's an updated version of an older, non-fiction work wherein Heinlein predicts a variety of events/changes that would occur over the next fifty years up until the year 2000.
Some of these are preposterous, some hilarious and some just bizarre.
Almost all of these predictions have failed to come true, with the exception being his prediction about the reduction in size of mobile phones. Many have actually run completely opposite to his beliefs; such as his prediction that the housing shortage would be resolved.
Whether or not you take his prognostications seriously, they do display Heinlein's militaristic world-view which makes it somewhat surprising that while many are wildly incorrect, several others could be argued to have come true in some form or another.
As for the other works in the book, 'Searchlight' clocks in at a mere 3 pages and feels like a synopsis for a story that was never written, while 'Blowups Happen' & 'Solution Unsatisfactory' are so similar in tone and subject matter (military industrial, nuclear/atomic technology) that they subconsciously blend into each other. 'Free Men' treads a slightly different path but continues Heinlein's grim vision of the future.
A modest collection but perhaps worth it alone for Heinlein's weird and wonderful predictions.

I hadn't read any Heinlein before and was hesitant to jump into something as apparently demanding as Stranger in a Strange Land without having done so, as it doesn't sound that intriguing to me. This collection is billed on the cover as containing his greatest stories and that doesn't exactly make me want to read more because I found his collection a boring chore to get through. Many of the ideas simply didn't interest me, particularly the first story about men going crazy guarding an atomic bomb, and the last one about a radioactive dust used in war. But even when they did interest me, like the story of a man who makes a machine that can predict death, I didn't care for the writing. There's little action or engaging description and tons of dialogue. I rarely feel put off by presenting information through dialogue, but I also wasn't looking to read screenplays.

So yea, no more Heinlein for me for a bit. I have another collection I'll read eventually but that's a long way away. A full novel is doubtful.

This book has 5 sci-fi stories, plus an introduction.

The Good
The introduction is interesting - Heinlein talks about his old predictions and admits when he was wrong
"Solution Unsatisfactory" is a solid story that predicted WWII and atomic weapons pretty well

The Problems
Too much talking, not enough action
Stories are "hit and miss" - some are okay, others are boring
Feels old and slow compared to modern sci-fi

Should You Read It?
Only if you're a big Heinlein fan or studying sci-fi history.

If you're new to Heinlein, read his novels instead.

It was interesting to see sci-fi from the 40s...some if it was (as is all good sci-fi) quasi-prescient and still relevant today. The way writers of the past thought the future (that is now past to us) would play out is always a trip. That being said, there was nothing here to really recommend to readers in general, but folks who enjoy ollllld sci-fi might enjoy these stories.

Surprisingly relevant, given its age, and quite interesting. It seemed there was a bit of misogyny and racism that found its way into several of the stories, but considering the era it was written in I suppose that's to be expected.

If you're planning on knocking out the 750-page beast of "Expanded Universe", it is the first book that later became "Expanded Universe". Early stories, some quite enjoyable!
