With all of the to-do over the Heinlein Centennial, the Wall Street Journal has a nice tribute by Taylor Dinerman available on-line.
Mr. Dinerman writes:
"The list of technologies, concepts and events that he anticipated in his fiction is long and varied. In his 1951 juvenile novel, "Between Planets," he described cellphones. In 1940, even before the Manhattan Project had begun, he chronicled, in the short story "Blowups Happen," the destruction of a graphite-regulated nuclear reactor similar to the one at Chernobyl. And in his 1961 masterpiece, "Stranger in a Strange Land," Heinlein--decades before Ronald and Nancy Reagan moved to the White House--introduced the idea that a president's wife might try to guide his actions based on the advice of her astrologer. One of Heinlein's best known "inventions" is the water bed, though he never took out a patent...
[One of Heinlein's characters says] "The power to tax, once conceded, has no limits; it contains until it destroys. I was not joking when I told them to dig into their own pouches. It may not be possible to do away with government--sometimes I think that it is an inescapable disease of human beings. But it may be possible to keep it small and starved and inoffensive--and can you think of a better way than by requiring the governors themselves to pay the costs of their antisocial hobby." As they say on the Moon, "TANSTAAFL!": "There Ain't No Such Thing as a Free Lunch!"
