...universe, the Arecibo dish will be enormously sensitive, concentrating the signals that fall on more than 18 acres. It will work best with radio waves about two feet long, but Dr. Gordon believes it will also pick up the important data-rich 21-cm. waves that come from hydrogen in the distant parts of the galaxy...
...upper stages of the moon rockets will burn liquid hydrogen, and the rocket manufacturers who work with the stuff claim that they will soon have it under control. But no hydrogen-burning engine has yet flown, and skeptics abound who believe that this tricky and touchy fuel will cause disastrous difficulties before it is tamed...
...overlap. Unfortunately broadcasting networks on this channel will transmit radio waves on the frequencies between 608 and 614 megacycles per second. Radio astronomers find this portion of the spectrum very useful because it is roughly an octave below (half the frequency) of the 21-centimeter line of unionized hydrogen. If Channel 37 becomes nationwide, all astronomical work on that band will be forced to stop because the sensitive antennas of the scientist will be receiving Gunsmoke instead of the Milky...
...Clay Pigeon. When the chiefs stepped down, it was the scientists' turn. Dr. Edward H. Teller, one of the developers of the hydrogen bomb and strong advocate of intensive atmospheric test ing, told the Senate that "the signing was a mistake. If you ratify the treaty, you will have committed an enormously greater mistake." Teller's chief objection was that the U.S. would be un able to perfect an anti-ballistic missile. Though he admits that a workable system would probably cost an astronomic $50 billion, he declared: "Missile defense may make the difference between our national survival...
Working with Brookhaven's powerful Alternating Gradient Synchrotron, they slammed a stream of antiprotons into a bubble chamber full of liquid hydrogen. As the antiprotons hit the stationary hydrogen nuclei-which were also protons-they annihilated each other, giving off energy and filling the 20-in. chamber with a sudden splash of new, extremely short-lived particles...
