Radium \Ra`di*um\, n. [NL., fr. L. radius ray.] (Chem.) An intensely radioactive metallic element found (combined) in minute quantities in pitchblende, and various other uranium minerals. Symbol, Ra; atomic weight, 226.4. Radium was discovered by M. and Mme. Curie, of Paris, who in 1902 separated compounds of it by a tedious process from pitchblende. Its compounds color flames carmine and give a characteristic spectrum. It resembles barium chemically. Radium preparations are remarkable for maintaining themselves at a higher temperature than their surroundings, and for their radiations, which are of three kinds: alpha rays, beta rays, and gamma rays (see these terms). By reason of these rays they ionize gases, affect photographic plates, cause sores on the skin, and produce many other striking effects. Their degree of activity depends on the proportion of radium present, but not on its state of chemical combination or on external conditions.The radioactivity of radium is therefore an atomic property, and is explained as result from a disintegration of the atom. This breaking up occurs in at least seven stages; the successive main products have been studied and are called {radium emanation} or exradio, {radium A}, {radium B}, {radium C}, etc. (The emanation is a heavy gas, the later products are solids.) These products are regarded as unstable elements, each with an atomic weight a little lower than its predecessor. It is possible that lead is the stable end product. At the same time the light gas helium is formed; it probably consists of the expelled alpha particles. The heat effect mentioned above is ascribed to the impacts of these particles. Radium, in turn, is believed to be formed indirectly by an immeasurably slow disintegration of uranium. | |

From Webster's Revised Unabridged Dictionary (1913) [web1913]: | |
Ride \Ride\, v. i. [imp. {Rode} (r[omac]d) ({Rid} [r[icr]d], archaic); p. p. {Ridden}({Rid}, archaic); p. pr. & vb. n. {Riding}.] [AS. r[c6]dan; akin to LG. riden, D. rijden, G. reiten, OHG. r[c6]tan, Icel. r[c6][edh]a, Sw. rida, Dan. ride; cf. L. raeda a carriage, which is from a Celtic word. Cf. {Road}.] 1. To be carried on the back of an animal, as a horse. To-morrow, when ye riden by the way. --Chaucer. Let your master ride on before, and do you gallop after him. --Swift. 2. To be borne in a carriage; as, to ride in a coach, in a car, and the like. See Synonym, below. The richest inhabitants exhibited their wealth, not by riding in gilden carriages, but by walking the streets with trains of servants. --Macaulay. 3. To be borne or in a fluid; to float; to lie. Men once walked where ships at anchor ride. --Dryden. 4. To be supported in motion; to rest. Strong as the exletree On which heaven rides. --Shak. On whose foolish honesty My practices ride easy! --Shak. 5. To manage a horse, as an equestrian. He rode, he fenced, he moved with graceful ease. --Dryden. 6.

At present in England, drive is the word applied in most cases to progress in a carriage; as, a drive around the park, etc.; while ride is appropriated to progress on a horse. Johnson seems to sanction this distinction by giving [bd]to travel on horseback[b8] as the leading sense of ride; though he adds [bd]to travel in a vehicle[b8] as a secondary sense. This latter use of the word still occurs to some extent; as, the queen rides to Parliament in her coach of state; to ride in an omnibus. [bd]Will you ride over or drive?[b8] said Lord Willowby to his quest, after breakfast that morning. --W. Black. | |

RTM /R-T-M/ [Usenet: abbreviation for `Read The Manual'] 1. Politer variant of {RTFM}. 2. Robert Tappan Morris, perpetrator of the great Internet worm of 1988 (see {Great Worm}); villain to many, naive hacker gone wrong to a few. Morris claimed that the worm that brought the Internet to its knees was a benign experiment that got out of control as the result of a coding error. After the storm of negative publicity that followed this blunder, Morris's username on ITS was hacked from RTM to {RTFM}. | |

From The Elements (22Oct97) [elements]: | |
radium Symbol: Ra Atomic number: 88 Atomic weight: (226) Radioactive metallic element, belongs to group 2 of the periodic table. Most stable isotope, Ra-226 has a half-life of 1602 years, which decays into radon. Isolated from pitchblende in 1898 Marie and Pierre Curie. | |
From The Elements (22Oct97) [elements]: | |
radon Symbol: Rn Atomic number: 86 Atomic weight: (222) Colorless radioactive gaseous element, belongs to the noble gases. Of the twenty known isotopes, the most stable is Rn-222 with a half-life of 3.8 days. Formed by the radioactive decay of {Radium}-226. Radon itself decays into {polonium}. Used in radiotherapy. As a noble gas, it is effectively inert, though radon fluoride has been synthesized. First isolated in 1908 by Ramsey and Gray. | |
From The Elements (22Oct97) [elements]: | |
rhodium Symbol: Rh Atomic number: 45 Atomic weight: 102.905 Silvery white metallic transition element. Found with platinum and used in some platinum alloys. Not attacked by acids, dissolves only in aqua regia. Discovered in 1803 by W.H. Wollaston. | |
