The Man Who Sold the Moon- Delos D. Harriman had wanted to go to the moon for his
entire life. An eccentric millionaire, Harriman had made
his money on "crackpot investments", and decides that his last and greatest venture would be to own the moon.
Using a simple use of logic, that when you buy a piece of land you not only own everything below it, but above it as well, Harriman purchases all the land that the moon rotates above. Ironically, in the end he cannot realize his dream, because his fellow corporate investors fear that the
journey would kill him.
Let There Be Light - The physicist Archibold Douglas and M.L. Martin worked extremely hard to perfect a new kind of solar collector that would solve the world energy crisis. However, they soon find that no one is willing to buy their invention. Faced with this dilemna, Douglas outsmarts the energy companies by offering his invention to anyone that is willing to pay a small royalty.
Life Line- Through his new invention, Dr. Hugo Pinero perfects a way to find the exact date of a person's death. He soon finds himself overwhelmed with business. However, not everyone is happy about this. Life Insurance Companies are quickly on the way to bankruptcy. In the end, they find that the best and quickest way to take care of the problem is to kill Pinero, and destroy his machine.
Throughout all of Heinlein's stories the dialogue follows one consistent style.
His characters dialogue never lags, but instead always stays to the point. But Heinlein's
style is one that also avoids the trap that many science fiction writers fall
into, that of the preacher. Since many science fiction stories
contain some new idea or plan, the author will often time set aside several paragraphs
for that idea. The Short intermission states the idea, but takes away from the
story. Heinlen's use of dialogue avoids this.
Heinlein's short stories seem to have a "David versus Goliath" thread. In "Let There Be Light", Archibold and Mary have to face the corporations, in "The Man Who Sold the Moon", Harriman has to face his partners, and in "Life Line", Pinero must face the life insurance companies. In all of these cases it is a group trying to stop an individual from trying to achieve his dreams. This romantic quality is part of the reason that Heinlein has stayed one of Science Fiction's most beloved writers
