Dear John: I'd like to say a word concerning Mr. Williams and the doppler effect. { refuse to speculate about the seriousness of the doppler effect at the velocity of light, because I don’t think the spaceship will reach this velocity, and say so in “On Atomic Jets,” which should appear in a future issue. But the doppler effect sure will make reception difficult, especially im the interstellar case. The bandwidth can’t be increased to allow for it; that would let in too much noise. Thus, the receiver has to be tuned to allow for the shifting fre- quency. Automatic frequency ‘control should take care of this. But, how do we find the signal in a hurry? We don’t, unless we know the relative velocity between transmitter and re- ceiver as well as the transmitter fre- quency.—J. J. Coupling. And they'd really have to be able to tune that receiver! What started out as microwaves would be coming in on the broadcast band! Dear Mr. Campbell: This is in response to both your recent editorial, “The Fallacy of Null-A,”’ and to Mr. Schott’s specula- tive thoughts on speculation, in the same issue. I am inclined not only to agree with your contention that all communication is of a “‘yes-no” na- ture—even though we do communi- cate tones and shades of meaning— and Mr. Schott’s assertion that “‘spec- ulation cannot be published”—but to add a correlation between the two: Because communication is Aristo- telian, speculation—or pure thought —cannot be published. For purposes of argument, let us define “‘published thought” as “al- most thought.” Almost, of course, means not quite. And thoughts are something that cannot quite be put into words, and still retain their origi- nal meaning. The process of changing pure thought, if it exists, and I believe it does, to black marks on a white page is a process which can never oper- ate at what a scientist would call one hundred per cent efficiency. 114 EComichooks.co im
