- I can't really help you, except that I'm sure the "solution without
- a problem" characterization was current while I was at MIT, in the
- early sixties. Townes had just joined MIT in some capacity or other
- (Provost?) and, to give the undergraduates a thrill (I don't mean that
- in any demeaning way -- it WAS a thrill), they had him come in and
- guest-lecture one of the 8.031 (Physics--Electromagnetism) lectures.
-
- I may be getting this mixed up, but it seems to me that he almost made
- a point of not using the word "laser." Seems to me he called it an
- "optical MASER" (please don't ask me what an optical microwave was).
- So it's possible that the correct quote might have been something like
- "the optical MASER is a solution without a problem?"
-
- The other thing that comes to mind, and unfortunately I don't have an
- exact quote or reference, is a story by Jack Finney. The story's been
- anthologized several times. I think the title is "Such Interesting
- Neighbors." It's a sort-of-science-fiction story, Finney leaning more
- toward fantasy -- a recurrent theme of his stories is that you can
- travel into the past just by YEARNING for the golden days gone by.
-
- Anyway, the gist of the story is that WE, but not the narrator, soon
- catch on that the neighbor is a time-traveller from the future, who makes
- his living by "inventing" those common items from his time that are
- technologically feasible in ours. I think the story was written in the
- fifties.
-
- One of the things his neighbor invents is a handy little gadget for
- measuring distance. It's about the size of a flashlight, but it has a
- dial on the side. I guess he's describing it to the narrator as something
- he's about to build. He says "you turn it on, and a beam of light comes
- out -- a special KIND of light -- and you can read off the distance on the
- dial, in feet, inches, and fractions." The narrator says "But how will it
- work?" The neighbor replies, "On flashlight batteries."
-
- At the time I read, I remember thinking, "What bulls--t. A special KIND
- of light, that's nonsense."
-
- So, if Arthur C. Clarke invented the communications satellite, did
- Jack Finney invent the laser (or optical MASER)?
