...things in science are impossible," said he. "but I do not believe that there is any great likelihood that even in four or five years from now there will be a really foolproof method of checking underground explosions down to, let us say, one kiloton [1,000 tons of TNT]. No matter how we proceed we cannot eliminate nuclear explosions of the tactical weapons size and perhaps not even some which can. serve as useful models for bigger explosions...
...kiloton is the equivalent in blast of 1,000 tons of TNT. The bomb that wrecked Hiroshima measured about 20 kilotons. In the strange vocabulary of nuclear weapons, a one-kiloton weapon is considered "small." A megaton is 1,000 kilotons, or the equivalent of 1,000,000 tons of TNT...
Terrorist bombs rocked Argentina last week, producing a crisis somewhat more serious than the many others President Arturo Frondizi has faced in his two-year regime. After TNT blasted an army intelligence major's home and killed his three-year-old daughter, Frondizi declared a state of "internal war"; police dragnets swept through the capital at night to knock on 1,400 doors and haul off 250 followers of ousted Dictator Juan Peron.

...boiling point: -252.7° C. at atmospheric pressure) that steel cracks on sudden contact. It must be elaborately refrigerated or it will flash into vapor. Even a small leak is highly explosive. The 150 gal. in Berkeley's chamber have the explosive power of 1,500 lbs. of TNT...
...There are intelligent buoys, which can be anchored at sea, and queried by radio for oceanographic and meteorological data. Other buoys sink to the bottom, where they can record currents, take pictures of their surroundings. They will be brought to the surface months later by a small charge of TNT exploded near by, which triggers their ballast-release mechanism...
